Canadian Human Rights Tribunal to revisit Air Canada retirement age issue

first_imgTORONTO – The Canadian Human Rights Tribunal will be revisiting the issue of whether Air Canada was wrong to force some pilots to retire at age 60.A decision publicly released on Friday says the tribunal will hold another hearing to determine whether the airline had the right to force 45 pilots to retire at an age it deemed to be the industry standard.The decision says the case originally had 97 complainants, but 52 of them will not have their retirement age scrutinized by the tribunal.The issue of retirement age for Air Canada pilots has come up both at the tribunal and in federal court numerous times in the past decade.Two cases with different complainants, but similar arguments, were ruled upon by the tribunal, reviewed in federal court, then ultimately dismissed by the Federal Court of Appeal.The tribunal says the 52 pilots whose retirement dates were covered by the previous cases will not be included in the new hearing, but says it will hear arguments from the remaining 45 whose retirement dates fall outside of the timeline covered by the other cases.A lawyer representing the majority of the pilots expects the new tribunal hearing will get underway in early 2018.Raymond Hall said he welcomed the latest development in the highly complex case.“We’ve been at it for 12 years,” he said Friday in an interview. “It’s no small thing.”The new tribunal hearing will unfold against the complicated backdrop of both the two past cases as well as changes in federal law.In 2011, as part of an omnibus bill, the then Conservative government passed a law forbidding federally regulated companies such as Air Canada to enforce a mandatory retirement age on its employees. The law went into effect in December 2012.Prior to that legislation, the issue of retirement age at Air Canada had been hotly contested on at least two occasions at the tribunal.The first case, named the Vilven/Kelly matter after its two plaintiffs, challenged Air Canada’s imposition of a mandatory retirement age of 60 for pilots forced to stop working between 2003 and 2005.Despite an initially favourable ruling from the tribunal, the case was challenged in federal court and ultimately quashed by the Court of Appeal.The second case, dubbed Thwaites/Adamson, involved 70 plaintiffs who retired between 2005 and 2009.That, too, received contradictory rulings from the tribunal and federal courts before ultimately being dismissed by the Court of Appeal.In both cases, Hall sought leave to bring the cases before the Supreme Court of Canada, but that leave was denied.The third and most recent group of complainants, referred to as Bailie et al, had retirement dates ranging from June 2004 to February 2012.Air Canada and the Air Canada Pilots Association, which represents the thousands of people who man aircraft for the country’s largest airline, had filed a motion to dismiss the Bailey complaint.Their primary rationale, according to the decision, was the fact that the issues at hand had been rehashed before in the two previous cases.Adjudicator David Thomas wrote in the decision that this held true for the 52 pilots who had retired before 2010, but that the 45 who retired after that date had not yet had a chance to air their grievances.While describing the possibility as improbable, he conceded that there may have been changes in the industry during those years that would make the forced retirement discriminatory on the basis of age.“While I am sympathetic to the respondents’ arguments that it is ‘highly improbable’ that a meaningful change to the material facts affecting the normal age of retirement occurred during the short period after Dec. 31, 2009 until the last Bailie complainant reached the age of 60 in February of 2012, I have not been provided with satisfactory information that there were no changes in the industry,” he wrote. “…it is not the role of the tribunal to speculate whether certain evidence may or may not exist. The tribunal has no investigatory powers and has no material evidence before it for the younger complainants. It is the right and the obligation of the parties to present that evidence to the tribunal in a quasi-judicial forum.”-Follow @mich_mcq on Twitterlast_img read more

Eerie Easter

first_imgNearly a decade after the 26-year long civil war in Sri Lanka came to a long-awaited close, the people of the island nation were crudely jolted with a series of coordinated attacks on churches and luxury hotels on Easter Sunday. Other nationals killed in the dastardly attack include Indians, Japanese and of USA. In solidarity with Sri Lanka, other nations and world leaders extended their condolences the grieving nation. On a day of worship and cheer, memories of the civil war were wrenched back in a flash. Faraz Shauketaly, a prominent journalist, spoke about the Sri Lanka Civil War and its connection to Sunday’s attack, reiterating that in Sri Lanka, the ethnic conflict began approximately 40 years ago and finished 10 years ago. The 3-decade long war was perpetrated by mainly a group of terrorists who claimed to want independence in the northern part of Sri Lanka, is a tiny island, about 240 miles long and 140 miles wide. May 18, 2019, will mark the 10-year anniversary of the end of the nation’s civil war fought between the Sri Lanka government and its Sinhala Buddhist majority and the Tamil Tigers minority ethnic group. Warning of more attacks in Sri Lanka, US Secretary of State Mike Pompeo commented that the United States will keep fighting “radical Islamic terror” in the wake of the Sri Lanka attacks. This comment very easily labels the mishap with a colour and a community that is otherwise vulnerable on the global stage. These attacks come in line with notorious attacks on churches, the latest being the fire that ravaged Notre Dame. The leaders of Sri Lanka, however, showed remarkable grit and insisted that the national suffering must not become a political game.last_img read more

Libyan deputy industry minister shot dead

first_imgTripoli – Assailants gunned down a Libyan deputy minister overnight, officials said on Sunday, in the first killing of a government member since the 2011 overthrow of dictator Moamer Kadhafi.Deputy industry minister Hassan al-Droui was shot dead during a to his hometown of Sirte, east of Tripoli, which was also Kadhafi’s hometown, security and hospital officials said.And in another sign of the instability plaguing the country, the toll from tribal clashes in the southern town of Sebha rose to 27 dead, with another 72 people wounded in the unrest. “Hassan al-Droui, the deputy minister for industry, was killed by unknown attackers overnight, during a visit to his native city of Sirte,” a security official told AFP.“Unidentified gunmen sprayed bullets on Mr. Droui in central Sirte,” the official said on condition of anonymity.A medical official at the city’s Ibn Sina hospital said Droui had suffered multiple gunshot wounds.The Libyan government denounced a “cowardly criminal act” and said in a statement it would “spare no effort to track down the perpetrators and prosecute them.”Droui was a former member of the National Transitional Council, the political arm of the rebellion that brought an end to Kadhafi’s 42-year rule.He was appointed deputy minister for industry by the transitional government’s first premier, Abdelrahim al-Kib, and kept his job when Prime Minister Ali Zeidan took office.Sirte, which lies on the Mediterranean coast about 250 miles (400 kilometres) east of Tripoli, was the last regime bastion to fall into rebel hands in the 2011 uprising during which Kadhafi was killed.Since the collapse of Kadhafi’s autocratic regime, Libya has been plagued by sporadic violence, including a string of assassinations targeting top army and security officials and the brief abduction of Zeidan.Deadly tribal clashesThe number of casualties from clashes between rival tribes in the southern town of Sebha and nearby Murzuq and Al-Shati rose to 27 dead and 72 wounded, a government statement said on Sunday.Fighting broke out in the area on Saturday pitting gunmen from the Arab Awled Sleiman tribe against tribesmen from the Toubou minority.Local sources said the clashes were sparked by the death on Thursday of a militia chief linked to Awled Sleiman, adding that the tribe accused the Toubou of murdering him.The Toubou are black oasis farmers by tradition who also live in southern Libya, northern Chad and Niger, who have repeatedly said they were being marginalised.A previous toll from the town’s local council had said that 19 died in the fighting and another 27 wounded.Fresh fighting broke out in Sebha on Sunday morning, witnesses reported.But in the afternoon the streets appeared to be calm, they said, adding that troops and policemen reinforcements were deployed in the town.The government said in a statement it sent reinforcements to secure residential areas and strategic installations in Sebha and that a “committee of elders” was trying to end the unrest.The fighting was the worst between the rival tribes since they struck a ceasefire agreement in March 2012 following deadly battles that killed at least 150 people and wounded 400 others.The Toubous have long complained of marginalisation by Libyan society, while Arab tribes have accused the minority of employing foreign fighters, particularly from Chad.The tribal clashes in Sebha could have a knock-on effect on production at several nearby oilfields in the mostly-desert south.Libya is currently struggling with a months-long oil crisis, which erupted when security guards at key oil terminals in the east shut them down, accusing the authorities of corruption and demanding a more equitable distribution of oil revenues.Oil Minister Abdelbari al-Arusi said last month that lost production from the blockades had cost Libya about $9.0 billion (6.6 billion euros) in revenues.last_img read more

The Seahawks Dont Stand A Chance Unless Russell Wilson Can Keep Up

The most anticipated matchup of the divisional round of the NFL playoffs might be the Atlanta Falcons’ No. 1 scoring offense against the Seattle Seahawks’ No. 3 scoring defense. But the game between the two teams may be decided when the ball is in Russell Wilson’s hand.When the two met in Week 6, the Seahawks edged the Falcons in Seattle, 26-24. But both teams have played a lot of football since then, and though Wilson has already led the Seahawks to eight playoff wins in his young career, he might not have enough talent around him to go into the Georgia Dome on Saturday and end the Falcons’ season.The most obvious change to either team has been the Seahawks’ loss of safety Earl Thomas; his five-year Pro Bowl streak ended when he missed five of the Seahawks’ last six regular-season games with injuries. With him patrolling the backfield, the Seahawks allowed just 16.4 points per game. In the Seahawks’ five regular-season games without him, opponents averaged 22.4 points, including 34 points in a home capitulation to the already-eliminated Arizona Cardinals.But as much as the Seahawks have missed Thomas, it is their offense that has struggled with explosiveness and consistency all season. The 26-6 final score of last week’s wild card game against the Detroit Lions might make it look as though the Seahawks are back to business as usual. But going into the fourth quarter the score was just 10-6.While the Seahawks’ offensive line earned praise for its dominant run-blocking performance against Detroit, it also allowed slumping Lions pass-rusher Ezekiel Ansah to register two sacks, as many as he tallied throughout the regular season. The Seahawks will have a much tougher task on Saturday when they face the Falcons’ Vic Beasley, who had 15.5 sacks in the regular season.Tailback Thomas Rawls set a franchise playoff rushing record against the Lions, but going into the rematch with the Falcons there’s little depth behind him. Christine Michael, the Seahawks’ top rusher in the first Atlanta game, now plays for the Green Bay Packers. Head coach Pete Carroll told reporters that C.J. Procise, who has been out since Week 11 with a shoulder injury, will be a game-time decision; fifth-round rookie Alex Collins would be the only option behind Rawls if Procise can’t go.Between Michael, tailback C.J. Spiller and receiver/returner Tyler Lockett, 43 percent of the Seahawks’ 333 total yards in Week 6 were produced by players no longer on the Seahawks active roster, and the Falcons still outgained them 362-333 in that game. Wilson targeted wideouts on just 43.2 percent of his attempts; according to Pro Football Reference’s charting, he attempted only two passes deeper than 14 yards all day. He threw no touchdowns.The lack of deep passing that day was partly by design, to keep opposing pass-rushers off the banged-up Wilson.“We’ve been careful in how we would expose Russ,” head coach Pete Carroll later told the team’s official site. “He was begging us to do more and all that, but we were trying to do the right thing by him, and he was doing phenomenal things just to play for the last two months.” But Wilson’s adjusted yards-per-attempt didn’t increase meaningfully after that interview.Though three rushing touchdowns got Seattle the points they needed to win in Week 6, they might not have happened if the Falcons hadn’t set them up: Ryan’s sack-fumble on his own nine-yard line led to the game’s first score; his interception near midfield set up the last one.Even then, it almost wasn’t enough. The Seahawks’ final go-ahead field goal still left Ryan and company with a 1:57 to drive for a game-winning score; a controversial fourth-down no-call sent them packing:Since that play, however, the Falcons spent the season improving — and proving themselves the better team.In Football Outsiders’ Weighted DVOA, which prioritizes recent performance, the Falcons are the No. 4-ranked overall team at 19.8 percent; the Seahawks are ranked 14th at 4.7 percent. While the Seahawks’ offense ranked 17th in both season-long (-2.7 percent) and weighted (-2.1 percent) DVOA, the Falcons’ defense rises from 27th (8.1 percent) to 22nd (5.6 percent) when recent games are more heavily weighted.Now Wilson will have go on the road and score more points against the improved Falcons than Ryan can score against the Seahawks’ struggling defense.Check out our latest NFL playoff predictions. read more

Carrick believes Mourinho nurtures young players

That’s the constant challenge though, isn’t it? That’s what everyone wants to see, that next one,” he added.“They say it’s getting harder. But that’s a challenge for us as a club and for English football – you might not get tens and twenties, you might get five or six players – but it’s got to keep happening.”“At the end of the day, the academies are there to produce players and to give kids a chance of getting in first teams. Especially at United; you can’t ignore the history and traditions,” he continued.“When people ask me: ‘What’s my role now [at the club]?’ That’s a big part of the club. You can’t just neglect the history of the club and what it stands for. And bringing players through is a huge part of that. It’s always been that one, two, three, four – more players in some eras.”last_img read more

Jamaicans Urged To Follow Guidelines In Voting Process

first_imgFacebook Twitter Google+LinkedInPinterestWhatsAppKINGSTON, Feb. 18 (JIS): With the General Election slated for February 25, Jamaicans are being encouraged to follow the necessary guidelines, to ensure that the voting process proceed as smoothly as possible.In an interview with JIS News, Public Education Officer at the Electoral Commission of Jamaica, Daynia Harper, said before the Election Day, persons should find out where they are to vote.“We encourage you to visit our website at ecj.com.jm and click on query voters’ list. It will ask you for your name and date of birth and after that we will prompt you about where you are to vote,” Ms. Harper said.She is also reminding voters to take along their voter identification card to the polling stations.“The voter’s ID card is the only identification card that is accepted on that day. However, if you do not have that card, you may still vote, but it will take a longer time for you to be able to cast your ballot,” she added.On arrival at the polling station, Jamaicans are being encouraged to join the line and wait until it is their turn to vote.Importantly, the use or display of cameras, cellular phones or any other image-capturing device is banned inside the polling station, and persons are being urged to turn off their cellular phones inside the polling stations.“Another thing you need to do when you get to the polling station, is to turn off and put away your cell phones. Do not attempt to use or display your cell phones or cameras or any kind of video recorders in the polling station,” Ms. Harper warned.If individuals attempt to use their cell phone or any smart device to do a recording, he or she will be asked to leave the polling station and will lose their chance to vote. In addition, voters must follow the instructions of the Presiding Officer in order for their ballot to be successfully marked and cast.“The Presiding Officer will show you how to fold your ballot and you will go behind the screen. You will mark your ballot with an ‘X’ for the candidate you wish to vote for and then you will refold your ballot in the exact way that the Presiding Officer has shown you. You will return with the ballot and you will dip your finger in the ink and watch as the Presiding Officer puts your ballot into the ballot box,” Ms. Harper said.Meanwhile, voters are encouraged not to try and influence any other voter to vote for a particular candidate. “If you show anyone your ballot, it will be taken from you by the Presiding Officer and marked as spoilt. You will, however, be given another chance to vote. But we encourage you – do not show anyone your ballot,” the Public Education Officer emphasised. Workers desirous of casting their ballots on Election Day are allotted time off from work to do so under the Representation of the People (Leave and Symbols) Regulations, 1944.They are allowed three hours, in addition to the normal meal hour, for voting purposes on a national and local election day.For more information about the voting process, persons may contact the Electoral Commission by calling toll free: 1-888-991-8683 or visit their Facebook page or follow them on Twitter @ecjamaica.

Govt retains control over lower courts

first_imgThe government has issued a gazette notification on the conduct of lower court judges, keeping provision for various measures to be taken in consultation with the Supreme Court.The president or the ministry or the division concerned has been defined as the proper authority to take such measures, according to the much talked about gazette on ‘Bangladesh Judicial Service (Discipline) Rules 2017’ issued on Monday.Rules of control and discipline for of the lower courts have been defined in the article 116 of the constitution in which the focal point is the president who is supposed to apply such authority in consultation with the Supreme Court.Such constitutional provision has been reiterated in the rules framed for the first time since separation of the judiciary from the executive. The rules came into effect immediately with the issuance of the gazette notification on Monday.Briefing the media about the gazette at a programme, law minister Anisul Huq obliquely blamed former chief justice Surendra Kumar Sinha for the delay.Issuance of the rules became a bone of contention between the government and the then chief justice. Once the government sent the draft of the rules to justice Sinha, he returned it, terming it incompatible. Eventually, the law minister finalised the rules after consultation with the acting chief justice Md Abdul Wahhab Miah.The president or the ministry or the division concerned will try to determine through primary investigation if certain matters would require thorough investigation when any member of the judicial service would be posted on deputation, said the rules.If the allegations are proved to be true through primary investigation, the authority proper will take steps for thorough investigation following consultation with the Supreme Court.The process to determine authenticity of allegations or prosecution against an official of the judicial service could not be initiated without giving him/her opportunity to defend or without consultation with the Supreme Court, according to the rules.The rules said the authority proper will be able to suspend an official of the judicial service during filing of a departmental case or any stage of the case, following consultation with the Supreme Court. Final order on the departmental case must be issued on completion of the investigation within one year of the suspension, the rules added. If the allegations are proved to be true, punitive measures should be taken in consultation with the Supreme Court.On 2 December 1999, the Appellate Division of the Supreme Court handed down its judgement with a 12-point directive while disposing of the Masdar Hossain case on separation of judiciary from the executive. The directives included framing of rules on the lower court judges’ discipline.After the recent tug-of-war between the government and the Supreme Court, the law ministry finally issued the gazette notification of the rules.last_img read more

There and back again Extending optical storage lifetime by retrieving photon echoes

first_img © 2014 Phys.org , Physical Review Letters “For this reason, research on quantum optical memories attracted a lot of attention,” Akimov told Phys.org. “Current investigations of photon echoes have concentrated primarily on atomic vapors and rare earth crystals with long storage times, which are crucial for implementation of robust light-matter interfaces. However,” he noted, “light-matter coupling is weaker in these systems, so operation speed is not as fast as it could be in semiconductors. For example,” he illustrated, “efficient optical excitation in atomic systems is possible with optical pulses longer than one nanosecond, which slow down the operation speed by three orders of magnitude as compared to our protocol – and for rare earth crystals the pulse duration should be even longer.”In contrast to classical storage, quantum memory forbids measurement of the optical field during saving and retrieving processes. “In other words,” Akimov said, “storage of non-classical quantum light – such as squeezed light or a single photon – should occur without knowing which optical fields have been stored and retrieved, because otherwise the quantum state would be irreversibly destroyed during the measurement procedure. However, our protocol allows quantum storage since transfer between optical excitation and spin excitation does not require state measurement.” In other words, the new protocol transfers a quantum superposition between optically coupled states (optical excitation) and the other pair of states coupled by a magnetic field (spin excitation). In this process no measurement takes place – just the transformation between different excitations.Regarding the quantum well, the researchers specifically concentrated on an n-doped CdTe/(Cd,Mg)Te quantum well where storage time increased from picoseconds to tens of nanoseconds. The structures were grown by Prof. Grzegorz Karczewski and Prof. Tomasz Wojtowiczin the Institute of Physics, Polish Academy of Sciences in Warsaw using molecular beam epitaxy. (CdTe/(Cd,Mg)Te is a cadmium telluride compound in which some of the cadmium is replaced by magnesium.) “The cadmium telluride semiconductor quantum well structure is a model proof-of-principle system for extending the photon echo delay,” Akimov told Phys.org. “In such two-dimensional structures, the carriers are confined in one direction; this results in well-defined spin-level system and clean selection rules for optical transitions. Secondly, n-type doping of barriers with donors provides excess electrons in the quantum well which, again, are responsible for long-lived spin excitations.”That said, while using cadmium telluride quantum wells enabled very clean experiments on the ensemble of trions to be performed because their optical transitions are well isolated spectrally, the researchers had to maintain weak optical pulse intensity to prevent interactions between weakly localized trions. “In order to increase the efficiency and to achieve longer delays for photon echoes it is necessary to try different type of semiconductor nanostructures which can be also based on other compounds.,’ Akimov explained. “One of such candidates is the ensemble of quantum dots where the electrons and holes are localized much more strongly in all three dimensions. This is in contrast to quantum wells where strong confinement is present only along one direction.”Finally, Akimov noted that in semiconductors there are two types of fundamental optical excitations: excitons (electron-hole pairs bound by Coulomb interactions) and trions – charged excitons consisting of an exciton bound with an excess electron or hole. “A trion is a three-particle complex, and after its decay there’s always an excess carrier left,” he explained. “In our case, we deal with excess electrons which possess spin 1/2. Therefore, in contrast to excitons, it is possible to save information about optical excitation in the spin of the excess electrons left after trion recombination. This transformation is only possible when an external magnetic field is applied, since it allows us to mix the electronic states in the proper way.” The most salient advantage of quantum well structures is that exciton and trion resonances are spectrally well separated – meaning that picosecond laser pulses let the researchers address only the optical transition from excess electron to trion.For all of these seemingly daunting challenges, the researchers’ key insight was to study photon echoes emitted by trions in semiconductor nanostructures subject to an external magnetic field – and by then using a transient four-wave mixing (FWM) technique to measure magnetic-field-induced long-term photon echoes, they were able to show that photon echoes can be retrieved from excess electron spin ensembles. (Transient four-wave mixing belongs to time-resolved coherent spectroscopy based on non-linear optics, whereby interactions between two or three optical pulses in medium produce fourth optical field in the signal) “We used ultrashort optical pulses with duration of about one picosecond,” Akimov explained, “because efficient optical excitation in semiconductors is possible on the order of 0.1-1ps.” In addition, he said, the experiments had to be performed at extremely low temperatures – about two degrees above absolute zero – in order to keep the system robust against interactions with phonons (collective excitations, similar to quasiparticles, in a periodic, elastic arrangement of atoms or molecules in condensed matter, such as solids and some liquids), as well as to suppress other relaxation mechanisms which could lead to irreversible dephasing of optical and spin excitations and thereby loss of coherence. “From an experimental point of view,” he added, “our primary challenge was combining four-wave mixing with ultrashort picosecond pulses and external magnetic fields at low temperatures.”The current study demonstrates that photon echoes can be retrieved from the spin system on the timescale of 10-100 ns. “However,” Akimov said, “this time delay is still too short for practical applications. In order to solve this problem we need to extend the decay time of spin excitations.” There are two possible reasons for decay of spin excitations: dephasing of spins and irreversible spin relaxation through decoherence – that is, due to interaction with the environment. “The first point can be addressed by means of spin resonance techniques using dynamic decoupling,” he explained, “which is an approach largely the same as photon echo but based on periodic excitation of the spin ensemble with microwave pulses which lead to spin echoes. In that way it will be possible to keep the spin ensemble of excess electrons free of dephasing, and timescales up to tens or even hundreds of microseconds may be achieved. However, irreversible spin relaxation is more difficult to solve – but there are several attempts to reduce hyperfine interaction between nuclear and electron spins. One of the solutions would be to use compounds with isotopes carrying zero nuclear spin. In this case storage times in the milliseconds can be available.”In fact, Akimov added that the scientists plan to investigate extending the timescale of photon echoes further into the microsecond and millisecond range. “We’ll test other nanostructures, such as quantum dots with strong trion localization, and will search for new materials with suppressed spin excitation decay. In addition,” he said, “we’ll use spin resonance techniques in order to eliminate spin dephasing in the ensemble of excess electrons.”Akimov also mentioned applications beyond optical memory. “While most applications are related to optical memories where the optical information should be saved and released on demand,” he said, “there’s another fundamental aspect: Our studies combine optical and spin phenomena, and in this sense it’s very interesting to explore our approach for monitoring the time evolution of combined optical and spin excitations.”A unique feature of photon echo experiments is the dephasing which already occurs at the initial stage directly after excitation with the first pulse, where the sequence of two linearly polarized pulses create comprehensive spin distribution for excess electrons without net spin polarization. While each of the electrons has a certain well-defined spin, the ensemble spin polarization, or average spin, is zero – and the information about the optical pulses, such as polarization and interpulse delay, is encoded in the spins of excess electrons. “This differs from conventional techniques,” Akimov pointed out. “For example, in well-established pump-probe experiments the non-zero spin polarization in the system is first induced by a circularly polarized pump pulse, and then the evolution of the spin in time is probed.” The scientists therefore believe that their approach based on photon echoes in a magnetic field constitutes an interesting platform for fundamental spin studies.Along these exploratory lines, Phys.org asked Akimov if, given that storage times of seconds or longer might be possible by further exploiting the hyperfine interaction between electrons and nuclei in quantum dots, quantum wells and self-assembling quantum dots might at some point be combined in a single quantum system that emulates human short- and long-term memory. “I think we are still far from that,” he replied. “In order to achieve this goal it would be necessary to establish a net of such quantum dot ensembles, analogous to cells, which would communicate between each other.” He added that while he does not exclude such possibility, he emphasizes that such a quantum system would very complex and would contain and integrate far more than a simple set of quantum nanostructures. “Several challenging issues such as communication between different ensembles have to be addressed, and for that it is necessary to accomplish directed and selective coupling of light at the nanoscale in and out of the cells. Accordingly, realization of such a network would need integration of photonic crystals or waveguide layers which can be based on semiconductors. Nevertheless,” he concluded, “this is a special area of research which deserves a lot of attention.” This document is subject to copyright.

Journal information: Nature Photonics Explore further Schematic presentation of the main mechanisms responsible for magnetic-field-induced stimulated photon echoes (SPE). The whole process comprises three steps: 1. pulse 1 creates the optical excitation (initialization—conversion of the optical field into a material excitation); 2. pulse 2 performs a transformation of the optical excitation into the spin system (storage); 3. pulse 3 stimulates the photon echo (readout). Optical pulses are circularly polarized. (A) Transfer of optical coherence into electron spin coherence (Sx and Sy components). The efficiency is maximum for t12=p/wL. (B) Creation of spectral spin fringes for electrons and trions (Sz and Jz components). This mechanism is most efficient for t12=2p/wL. The spectral spin gratings for electrons and trions are shown in (C) at the moment of creation by the second pulse (t=t12=2p/wL) and in (D) after trion recombination and before arrival of pulse 3 (t>>t12+T1).

In turn, this induced stimulated photon echoes with high bandwidth on submicrosecond timescales that exceeded optical excitation lifetime by a factor exceeding three orders of magnitude. Moreover, the scientists state that the ability to address all three spin components –parallel and perpendicular to applied magnetic field – as well as the energy level structure of localized trions being identical in quantum wells and self-assembled quantum dots make their approach “highly appealing” for future memory device applications and may lead to the fabrication of semiconductor nanostructure-based optical memories.Dr. Ilya Akimov discussed the paper that he, Doctoral Student Lukas Langer and their co-authors from Dortmund, St-Petersburg and Warsaw published in Nature Photonics, starting with the main challenges in devising a new experimental approach to stimulated photon echoes by transferring the information contained in the optical field into a spin system, where it is decoupled from the optical vacuum field. “A photon echo can be considered as a flash of light initiated in a medium after a sequence of two or more optical pulses,” Akimov told Phys.org. “Properties of the photon echo pulse – that is, intensity, optical coherence and phase – are identical to the properties of the initial pulse; therefore this phenomenon can be used to store information in all-optical systems.” Photon echoes because they occur in structures which rapidly dephase optical excitation in response to the first pulse, but with the second pulse reverse the dephasing process. Akimov pointed out that the timescale at which photon echoes can be observed is determined by the period during which optical excitation coherence is preserved. “This is why photon echoes are coherent,” he explained. “If scattering processes are suppressed, optical excitation coherence is limited by its lifetime as governed by intrinsic properties of the materials. Nevertheless there is a general rule that the more efficient light-matter interaction, the faster decay into the ground state will be observed – for example, faster spontaneous emission due to the optical vacuum field. Here we have a dilemma,” he noted. “On the one hand, we’d like to excite the medium quickly with the shortest possible pulse, which requires strong light-matter interaction. However, this limits the timescale at which the photon echoes can be observed.” The opposite is also true: To observe long-lived photon echoes, materials with weak light-matter coupling are needed – and although semiconductor systems belong to materials with strong light-matter interaction, it’s possible to extend photon echo decay if the optical excitation is transferred into the spin excitation and then recovered back to the optical excitation – that is precisely what Akimov and co-authors have accomplished. Quantum holograms as atomic scale memory keepsake “In order to achieve this goal,” he said, “we’ve used semiconductor quantum wells with excess electrons.” (A quantum well is a thin layer which can confine quasiparticles – emergent phenomena that occur when a microscopically complicated system, such as a solid, behaves as if it contains weakly interacting particles in free space – in the dimension perpendicular to the layer surface.) What’s key is that the spin excitation coherence time of such electrons decays three orders of magnitude more slowly than the lifetime of optical excitations. “In our protocol the first pulse leads to optical excitation in semiconductor quantum well; next, after dephasing of the optical excitation the second pulse transfers optical excitation into the electron spin excitation; and finally – even after a long delay, which can be 1,000 times longer than the delay between the first and second pulses – we apply the third pulse.” This third pulse transforms spin excitation back to optical excitation and initiates rephasing, so that resulting photon echoes are retrieved from the spin ensemble – and therefore the third pulse can be associated with the readout of optical information previously saved by the optical-to-spin transformation induced by the second pulse.”The unique feature of photon echoes is that they contain the information about the first optical pulse,” Akimov pointed out. “Therefore, photon echoes can be used for information technology optical memory applications. Moreover, it’s possible to perform not only classical light storage but to use photon echoes for realization of quantum optical memories.” This is essential, he stresses, for the development of quantum information and communication systems which use the laws of quantum mechanics to significantly enhance the speed and capacity of future computers.

That being said, optical storage is a complex process that depends largely on the material being used to convert, store and retrieve this information in a controllable, consistent manner – a process especially prone to short optimal memory times when implemented in certain semiconductor quantum structures. Recently, however, scientists at Technische Universität Dortmund, Germany in collaboration with Saint Petersburg State University, Russia and Institute of Physics in Warsaw, Poland demonstrated magnetic-field-induced long-lived stimulated photon echoes1 – coherent optical phenomena in which resonant excitation of a medium by short optical pulses results in a delayed coherent optical flash response – in the electron–trion system, allowed the bidirectional coherent transfer of quantum information in a semiconductor between optical and spin excitations. (Trions are excitations comprising three charged quasiparticles – emergent phenomena that occur when a microscopically complex system, such as a solid, behaves as if it contained different weakly interacting particles in free space.)last_img read more

Researchers suggest coal ash and tailings dam disasters could be prevented

first_img © 2019 Science X Network More information: J. Carlos Santamarina et al. Why coal ash and tailings dam disasters occur, Science (2019). DOI: 10.1126/science.aax1927 Iron mining produces a waste product known as tailings. Tailings are typically dumped into man-made ponds, which are more often than not dammed up to prevent them from oozing downhill when it rains. Similar ponds are constructed to contain coal ash waste produced by coal power plants. Besides representing a pollution problem, the ponds are also mudslide hazards. The researchers point out that thousands of people around the world have been killed by such mudslides over the past century. They suggest it is time that governments engage more fully with those building and maintaining such ponds.The researchers note that mudslides from tailings or coal ash occur when the dam holding the material gives way. Many people believe that the reason such dams give way is because of the pond contents and what happens to them. Evidence of liquefaction of pond materials is almost always in evidence along mudslide routes. But prior study has shown that liquefaction almost always happens after the dam gives way, not before. Instead, the researchers suggest that the major reason for most of the disasters is failure to follow best engineering practices in building and maintaining the dams.One of the biggest problems, the researchers point out, is that proper action is not taken during heavy rain causing overflow, which puts excess stress on the dam. Another problem is layering on the bottom of such ponds that result in deposits with different hydromechanical properties—this usually leads to weaknesses in the system. Also, cementation can loosen sediment structures, which can also weaken the system. And problems can also develop when material is compressed near the dam. They note also that preexisting weaknesses in the foundation of the dam can lead to failure later, and so can piping erosion or mineral buildup.The researchers conclude by suggesting more attention to such ponds, because the mudslides that can result when they fail appear to be far more preventable than many in the field have suggested.

Frequent school changes hurt kids math scores

first_imgStudents who change schools frequently are at risk of lower math scores and have a harder time managing their behaviour and attention in the classroom than students who stay in the same school, says a new study.Children who experienced fewer school transitions over a five-year period, demonstrated greater cognitive skills and higher math achievement in early elementary school, relative to their counterparts who changed schools frequently, showed the findings of the study. Also Read – ‘Playing Jojo was emotionally exhausting’All the children in the study were from low-income families in Chicago. “Simply stated, frequently changing schools is a major risk factor for low-income children’s school success,” said the study’s lead author Allison Friedman-Krauss from New York University.Data for the study came from 381 children (52 per cent girls) enrolled in the Chicago School Readiness Project. On average, children in the study scored in an acceptable range on standardised math tests in fourth grade.  However, children who moved frequently were predicted to score, on average, 10 points lower than their peers who did not change schools frequently, the authors wrote. Also Read – Leslie doing new comedy special with Netflix“Although moving once or twice may not be extremely detrimental to the development of children who are already at risk, moving almost every year during elementary school increased the probability that students would face more difficulty in the long run,” study co-author C Cybele Raver, professor of applied psychology at New York University noted. This suggests the need for policies at the state, district and school levels to prevent school changes and to support students, families and teachers when children do change schools,” Raver pointed out. The study was published in the American Psychological Association’s journal Developmental Psychology.last_img read more

Some 36 of smartphone owners and 35 of tablet ow

first_imgSome 36% of smartphone owners and 35% of tablet owners search for product or service information on the device while watching TV, according to new research by US-based Parks Associates.In a new report, released ahead of the Connections connected home conference in Las Vegas next week, the market research firm said that consumers are increasingly using mobile devices and second-screen apps as alternatives to traditional remote controllers and interactive programming guides.Citing second screen apps for shows like Glee and Breaking Bad, Parks Associates said that over one-third of device owners now regularly use apps to search for show-related information or to check listings.“Younger viewers are driving this change in viewer habits. Over 25% of millennials (aged 18-30) with a smartphone engage in second-screen activity at least weekly while watching TV. Further, almost 20% of these millennials access pay TV programs via their service provider on their smartphone, a rate 1.6 times higher than the general smartphone population,” said Parks Associates senior research analyst Heather Way.last_img read more

first_imgSponsor Advertisement It was just another day when JPMorgan et al threw everything they had at the precious metals to prevent them from blowing sky highAs I stated in ‘The Wrap’ yesterday morning just minutes before my 5:20 a.m. Eastern time filing deadline…”It remains to be seen whether these rallies [in gold and silver] continue in London…or get stepped on before New York opens…”With the benefit of 20/20 hindsight, it’s easy to see that virtually all the excitement was over by 9:20 a.m. BST in London.  There was a vertical price spike at 1:00 p.m. BST, twenty minutes before the Comex open…but it got hammered flat in pretty short order.  The rally after the London p.m. gold fix at 10:00 a.m. Eastern time wasn’t allowed to get too far, either.Gold closed at $1,701.30 spot…up $7.90 on the day.  Net volume was pretty enormous…around 190,000 contracts, so it should be obvious that gold’s attempt to rally well over the $1,700 price mark was not going unopposed…and that JPMorgan et al were going short against all comers.It was virtually the same story in silver…and the price pattern was virtually identical, as you can see from the Kitco chart below.  Silver closed at $32.71 spot…up 44 cents from Wednesday’s close.  Volume was very heavy as well…around 57,000 contracts.The dollar index opened on Wednesday night in New York at 81.20…and then declined in fits and starts down to about 81.07 at 8:00 a.m. in New York.  Then at precisely that moment…the moment that both gold and silver began to spike higher at 1:00 p.m. in London…the dollar index turned on a dime, reaching its 81.42 zenith about 9:40 a.m. in New York…and by 11:00 a.m. Eastern that entire gain had reversed itself.  The dollar index closed at 81.12…down about 8 basis points from Wednesday.If you check the above gold and silver charts, you will note that all the major price activity in New York in both gold and silver happened precisely between those two times.  Hardly a coincidence, I’m sure.The gold stocks gapped up…and after a bit of sag, worked their way slowly higher for the rest of the day.  The HUI finished on its high tick…up 2.67%.The silver stocks were mostly up on the day…but there were a few red arrows amongst the green ones.  Nick Laird’s Silver Sentiment Index closed up another 1.44%.(Click on image to enlarge)The CME’s Daily Delivery Report showed that 5 gold and 157 silver contracts were posted for delivery within the Comex-approved warehouse system on Monday.  In silver, the big short/issuer was the Bank of Nova Scotia…and to no one’s surprise I’m sure, JPMorgan was the biggest long/stopper with 93 contracts in its proprietary [house] account…along with 46 contracts in its client account.  The link to yesterday’s Issuers and Stoppers Report is here.The CME’s preliminary volume report for yesterday shows that only 1,103 silver contracts remain open in September.  That’s almost a 50 percent drop since Monday.There were no reported changes in either GLD or SLV…and the U.S. Mint didn’t have a sales report, either.Wednesday was another active day over at the Comex-approved depositories.  They received 926,750 troy ounces of silver…and shipped 1,116,483 troy ounces of the stuff out the door.  Here’s the link to that activity.Nick Laird sent me his “Transparent PM Holdings” chart very late last night…and it’s definitely worth looking at.  As Nick pointed out…”it’s still hitting new highs day after day.”(Click on image to enlarge)I have the usual number of stories for you today…and the final edit is yours.Well, it was just another day when JPMorgan et al threw everything they had at the precious metals to prevent them from blowing sky high…as the volume figures were enormous, especially in gold.Today we get the jobs report at 8:30 a.m. Eastern…and as I say every month at this time, it will be interesting to see how gold reacts to this data…or is allowed to react.  I’ve noticed in the past…that there are times that ‘da boyz’ will soften up the price in advance of the jobs numbers, especially if they’re particularly bad, so that when the gold price does pop at 8:30 a.m….the precious metals have a hole to dig themselves out before turning positive on the day.  That may [or may not] be what went on in the precious metals market earlier today.  We’ll see.We also get the Commitment of Traders Report as well…and I’ll be waiting at the keyboard at precisely 3:30 p.m. Eastern time, which is when they post it on the CFTC website.  I’ll have that data in tomorrow’s column.As I mentioned two paragraphs ago, both gold and silver came under some selling pressure in Far East trading on their Friday.  The lows in both gold and silver were in around 1:00 p.m. Hong Kong time…and are continuing to rally now that London has been open for a bit more than two hours.  It will be interesting to see how long that lasts, or is allowed to last.  Gold volume is already very high…around 35,000 contracts and, like yesterday, silver’s volume is at 12,000+ contracts once again.  The dollar index is down about 20 basis points, gold is down about six bucks…and silver is down 50 cents as I hit the ‘send’ button at 5:18 a.m. Eastern time.With the exception of palladium, the other three precious metals are still well into overbought territory…especially silver.  Based on that, it will be interesting to see if JPMorgan et al can, or will, engineer another sell-off in the near future.  Here’s the 6-month silver chart.(Click on image to enlarge)With gold and silver shares roaring higher, there’s still an opportunity to either readjust your portfolio, or get fully invested in the continuing major up-leg of this bull market in both silver and gold…and I respectfully suggest that you take a trial subscription to either Casey Research’s International Speculator [junior gold and silver exploration companies], or BIG GOLD [large producers], with all our best [and current] recommendations…as well as the archives. Don’t forget that our 90-day guarantee of satisfaction is in effect for both publications.Today is another day where I look forward to the 8:20 a.m. Comex open with great interest.  Enjoy your weekend…and I’ll see you here tomorrow. Aben Resources (TSX.V: ABN) is a Canadian gold and silver exploration company with a focus on developing properties in the Yukon. The Company’s flagship project is its 100% owned Justin Gold Project located 35 kilometres southeast of the Cantung Mine and has an all season road running through its claims. A phase one drill program was carried out in 2011 on the 18,314 acre Justin Project in which a significant new greenfields gold discovery was made at the property’s POW Zone. The Company intercepted 60 metres of 1.19 g/t gold in hole JN11009 at a vertical depth of 113 metres. Additionally, a new high grade silver-copper zone was discovered at the Kangas Zone with hole JN11003 returning 1.07 metres of 7320 g/t silver (234 oz/ton) and 3.52% copper near surface. As a result of these discoveries on the Justin Project, Aben acquired 14,274 additional acres of mineral tenure in the immediate vicinity of the project to facilitate a more aggressive work program this upcoming season. The Company has four other prospective Yukon and NWT projects in its portfolio along with a seasoned management and geological team. Aben’s chairman, Ron Netolitzky, is credited with exploration success on numerous properties including three Western Canadian gold and silver projects which became producing mines.
