Report: Scientists ‘teleport’ two photons Citation: Physicists Propose Scheme for Teleporting Light Beams (2009, July 14) retrieved 18 August 2019 from https://phys.org/news/2009-07-physicists-scheme-teleporting.html In their study, Changsuk Noh, M.J. Collett, and H.J. Carmichael from the University of Auckland in New Zealand, along with A. Chia from Griffith University in Queensland, Australia, and Hyunchul Nha from Texas A & M University at Qatar in Dohar, Qatar, have proposed a scheme for teleporting a beam of light, including its fluctuations over time. They hope to show that it’s possible that a physical object (e.g. a quantum field) in one location could emerge at another location in the same quantum state, so that any conceivable measurement would yield the same result in both locations. In contrast, previous teleportation schemes do not seriously consider reproducing certain elements, such as temporal fluctuations.In their proposal, the scientists investigate using a stream of photons that are evenly spaced, or “antibunched.” Detecting the individual photons in a stream that is spaced similar to the photon stream at the input would verify teleportation of the full quantum field. The scientists wanted to find the conditions under which this detection could occur. They discover that squeezing light – a technique used to enhance precision measurements – could allow for teleportation of a quantum photon stream if the squeezing is across a broad bandwidth. “I would say that the greatest significance of our study is at the level of clarifying fundamental principles,” Carmichael told PhysOrg.com. “The original proposal for quantum teleportation is conceptually simple since the quantum state considered is carried by a material object – a particle. Alice and Bob are both provided with similar particles; the state of Alice’s particle is destroyed and acquired by Bob’s. When this idea is transferred to the teleportation of light, one faces a fundamental change, because the state of no light (the vacuum) is also a quantum state, and there is an infinity of ‘objects’ (modes or frequencies of light) in this ‘no light’ state. Every one of these has to be reproduced in the same ‘no light’ state in the teleportation. Our paper clarifies the distinction and shows how to achieve the necessary reproduction.” Explore further This document is subject to copyright.

(PhysOrg.com) — Usually when physicists talk about quantum teleportation, they’re referring to the transfer of quantum states from one particle to another without a physical link. Now, physicists have investigated a slightly different form of teleportation, in which they teleport a quantum field, or an entire beam of light, from one location to another. This kind of “strong” teleportation is required for some quantum information applications, and could lead to the teleportation of quantum images. The scientists note that the squeezing levels are demanding, but further investigations into designing experiments could reveal more optimal methods. One of the biggest challenges for realizing the proposal, as Carmichael explained, is the requirement for high quality, flexible sources of squeeze light.“The technology to realize the scheme is, at the level of fundamentals, already in place; but there are serious challenges in making the technology good enough to carry out an experiment,” he said. “The main step required is to improve the source of squeezed light. Improvements in two directions are needed: first, to achieve higher levels of squeezing, and, second, to squeeze at a high level over a broad bandwidth in the range of frequencies of the input light.”If physicists can overcome these challenges, the ability to transport light beams could lead to many interesting applications. For instance, the researchers suggest that a multi-channel version – in which two or more beams are teleported in parallel – could be used to teleport quantum images. “Comunications systems of the current classical sort send information in a patterned sequence of light pulses – a sequence patterned in time, something like the teeth of a comb with the teeth missing in various places,” Carmichael explained. “Our method of teleportation is able to send such a patterned sequence of pulses…in principle, even when each pulse is in an exotic quantum state or when the state of the whole string of pulses is entangled (a quantum comb whose tooth takes on interrelated ‘quantum colors’). Previous ideas about how to do this require a matched pattern of squeezed light pulses and a matched pattern of measurement pulses, both required to execute the teleportation protocol. Thus, our proposal finds application wherever the transmission of such patterned pulse sequences is needed, e.g., in certain schemes for quantum computation on a register of qubits.”Most importantly, teleporting light beams likely offers yet undiscovered potential. “The greatest significance of our study will therefore hopefully be realized in the minds of readers who come to understand clearly what it means to teleport a quantum field (beam of light), and what the technical challenges are if the full power of this mode of teleportation is to be exploited,” Carmichael said.More information: Changsuk Noh, A.

(PhysOrg.com) — The first compliant products, that will use Sony’s TransferJet technology, will start appearing in products as early as the spring of this year. Its design will enable file swapping, between two devices, by bringing them within approximately 3cm of each other. The TransferJet technology was first demonstrated at the 2008 International CES in January 2008. Sony stated that TransferJet would run at 560Mbps but users would only be able to achieve transfer rates of up to 375Mbps after networking overheads. © 2010 PhysOrg.com More information: Sony’s technology highlights- www.sony.net/SonyInfo/technolo … transfer_jet_01.html Image depicts transferring photos between a Sony Cyber-shot DSC-TX7 and Vaio F-Series laptop.

Sony’s transceiver IC is the core of TransferJet short-range wireless technology. Transferring data between gadgets is as simple as bringing them together. Sony released the transceiver IC to the merchandise market in November 2009. There are two host interfaces on the transceiver IC. One interface will support PCI and Mini PCI, and other supporting SDIO. The data transfer rate for the PCI and Mini PCI interface (rev 2.3) is approximately 300 Mbit/s and a minimum of 100 Mbit/s for the SDIO interface (V .2.0).Sony is working on a resolution to resolve the slow speeds for SDIO Ver. 2.0, which has a max data transfer rate of 200Mbit/s. With SDIO Ver. 3.0 already standardized, which allows for a maximum data rate to 104Mbyte/s, Sony expects to have TransferJet support SDIO Ver. 3.0 sometime in 2011.
Adding to the cost and complexity of the project would be the actual connecting together of the individual parts, likely with fiber optics and a controller that would have to not only position the nodes on the network, but would have to account for time lags as well, and as much as 20 GB of data per second from each of the telescopes.Like the Large Hadron Collider project, most of those involved in the SKA project expect that if it’s completed as hoped, new discoveries will be made with it that no one as yet can possibly imagine. (PhysOrg.com) — Proving that a lot of little things can go a long way, a group of astronomers have revealed plans to build and install a radio telescope array out of thousands of small inexpensive dishes, spread out over thousands of miles of remote territory. Known as the Square Kilometer Array (SKA) the telescope would be the largest of its kind ever created, and would give scientists clues about the creation of the universe, help understand dark matter, or even maybe, perhaps, help receive signals from other intelligent life forms.The SKA, so named because of the collective size of the dishes that would make up the system, would be comprised of over 3000 relatively inexpensive dishes that when connected together, and coordinated with a new, as yet undeveloped supercomputer, would result in a single radio telescope capable of delivering 50 times greater sensitivity than anything currently operating. And if that’s not enough, it would also provide 100 times the resolution.The group, comprised of scientists from over twenty countries, expect costs to be in the neighborhood of $2 billion, with construction starting sometime in the next decade and completion in 2024.A site for the proposed telescope has not yet been chosen, though several countries are vying for selection and the scientific prominence and influx of international cash that would result. The problem is, there are few optimal sites, due to the fact that all of the dishes would have to be situated in a place so remote that no people, cars, phones or other noise making devices would be in the vicinity. Currently, the leading contenders appear to be a block of countries in southern African and Australian and New Zealand. This document is subject to copyright.

Currently cow milk is not readily digested and absorbed by human infants, so for those mothers who choose not to breastfeed or who are unable, the only current alternative is formula. Many argue that infant formula is inadequate in providing the full nutrients an infant needs. Human milk contains numerous proteins as well as human lysozyme (HLZ), which is a key in fighting bacteria and boosting an infant’s immune system.With this in mind, Li and his team introduced human lysozyme and other human proteins into the embryos of Holstein cattle and then placed these embryos into surrogate cows. In this recent study, printed in Public Library of Science One, the researchers state that it was cloning technology used to introduce the human genes into the cows DNA. When these genetically modified cows started lactating, the milk they produced contained HLZ as well as other human proteins such as lactoferrin and lactalbumin which also help to boost an infant’s immune system. A purification process was then used to increase the fat content and milk solids, as well as make the milk taste closer to that of human breast milk. It is the researcher’s hope that one day we will be able to purchase this genetically modified cow’s milk in grocery stores.Protestors against the cloning and genetic modification of animals worry about the animal welfare, as well as the possible danger of exposing infants to this genetically modified milk. In one of the experiments in this study, of the 42 calves born, ten died not long after birth and the other six died within months. Health problems are not uncommon in genetically altered animals and they suggest this be taken into consideration before suggesting infants consume this milk. © 2010 PhysOrg.com
The orbit histories of giant planets in one of the simulation with ﬁve initial planets. Image credit: arXiv:1109.2949v1 [astro-ph.EP] (PhysOrg.com) — A new study published on arXiv.org shows that, based on computer simulations, Jupiter, Saturn, Uranus and Neptune may not have been the only gas giants in our solar system. According to David Nesvorny from Colorado’s Southwest Research Institute, our current solar system could never have happened without the existence of a fifth planet. More information: Young Solar System’s Fifth Giant Planet? arXiv:1109.2949v1 [astro-ph.EP] arxiv.org/abs/1109.2949AbstractRecent studies of solar system formation suggest that the solar system’s giant planets formed and migrated in the protoplanetary disk to reach resonant orbits with all planets inside 15 AU from the Sun. After the gas disk’s dispersal, Uranus and Neptune were likely scattered by gas giants, and approached their current orbits while dispersing the transplanetary disk of planetesimals, whose remains survived to this time in the region known as the Kuiper belt. Here we performed N-body integrations of the scattering phase between giant planets in an attempt to determine which initial states are plausible. We found that the dynamical simulations starting with a resonant system of four giant planets have a low success rate in matching the present orbits of giant planets, and various other constraints (e.g., survival of the terrestrial planets). The dynamical evolution is typically too violent, if Jupiter and Saturn start in the 3:2 resonance, and leads to final systems with fewer than four planets. Several initial states stand out in that they show a relatively large likelihood of success in matching the constraints. Some of the statistically best results were obtained when assuming that the solar system initially had five giant planets and one ice giant, with the mass comparable to that of Uranus and Neptune, was ejected to interstellar space by Jupiter. This possibility appears to be conceivable in view of the recent discovery of a large number free-floating planets in interstellar space, which indicates that planet ejection should be common.

When using just the four giant planets, every simulation found that they were too large and ended up destroying each other. In the simulations where they did manage to make it in one piece, the rocky planets such as Mars and Venus, were instead destroyed. According to his results, the current solar system structure would have a very low probability of occurring if it started with only four rocky planets and four gas planets.After running these simulations, Nesvorny decided to add a fifth large planet into the mix. With the addition of this large planet, results found that the odds of our current solar system increased significantly.The most successful simulations show that Jupiter, Saturn, Uranus, Neptune and a fifth planet, similar to that of Neptune or Uranus, started out all tightly packed and orbiting some 15 times further from the sun then our planet Earth. The lighter planets are sent out further by Jupiter and Saturn. A close encounter with Jupiter then ejects this mysterious fifth planet out of the solar system.Recent discoveries of free-floating planets in interstellar space show that the ejection of planets could have been common, according to the study. ‘Hot Jupiter’ planets unlikely to have moons This document is subject to copyright.

Journal information: Science African elephants produce “infrasounds,” which are low-frequency (<20 Hz) vocalizations capable of travelling up to 10 kilometers. Their frequency is usually too low for them to be audible to the human ear.A new study by an international team of voice scientists and biologists has cleared up the mystery of how these infrasounds are produced. The researchers studied the excised larynx of an elephant that had died of natural causes and tried to use it to create infrasounds in the laboratory.The study, led by voice scientist Christian Herbst of the University of Vienna, Austria, aimed to settle the long-standing question of whether elephants make infrasounds in the same way that humans and many other mammals produce sounds, by air flowing across the vocal folds to create vibrations, or through active contractions of the muscles. Scientists can study the process in humans by inserting cameras into the larynx and observing what happens when different sounds are made, but this method is not possible in living animals such as elephants.The research team excised the larynx within a few hours of the elephant’s death in a Berlin zoo, and they froze it and transported it to the University of Vienna’s Department of Cognitive Biology laboratory. They tested the larynx by adjusting the vocal folds to a position used for vocalizations (called a phonatory position) and blowing streams of humidified warm air through it to simulate the action of the elephant’s lungs. The larynx produced infrasounds virtually indistinguishable from those produced by living elephants.The results demonstrated that muscular activity is not required to produce infrasounds, and that they are produced by the flow of air, a type of vocalization known as myoelastic-aerodynamic or flow-driven mode. If elephants produced infrasounds through active muscular contractions, in the same way as a cat’s purr is produced, the larynx would not have produced the sounds with the brain absent. The research does not, however, prove that elephants never use active muscular contractions to produce any sounds.Myoelastic aerodynamic vocalization is the method used in humans (producing frequencies of about 50 to 7,000 Hz) and many other mammals, including echo-locating bats (100,000 Hz or higher). The researchers also found other features of the elephant larynx that matched “nonlinear phenomena” in other species, such as screaming in humans. In nonlinear vocalizations the vibration is chaotic rather than periodic. The paper was published on 3rd August in Science. Researchers solve mystery of long elephant pregnancy Explore further (Phys.org) -- Mammals produce sounds in two ways, either via the flow of air over vocal folds (vocal chords), as in humans and many other mammals, or via active muscular contractions as in the cat’s purr. Until now no one has been sure how elephants produce their lowest tones, but a new study has solved the mystery. More information: How Low Can You Go? Physical Production Mechanism of Elephant Infrasonic Vocalizations, Science, 3 August 2012: Vol. 337 no. 6094 pp. 595-599. DOI: 10.1126/science.1219712ABSTRACTElephants can communicate using sounds below the range of human hearing (“infrasounds” below 20 hertz). It is commonly speculated that these vocalizations are produced in the larynx, either by neurally controlled muscle twitching (as in cat purring) or by flow-induced self-sustained vibrations of the vocal folds (as in human speech and song). We used direct high-speed video observations of an excised elephant larynx to demonstrate flow-induced self-sustained vocal fold vibration in the absence of any neural signals, thus excluding the need for any “purring” mechanism. The observed physical principles of voice production apply to a wide variety of mammals, extending across a remarkably large range of fundamental frequencies and body sizes, spanning more than five orders of magnitude.

Washing your hands in hot water may be pointless as scientists have found that cold water is equally effective at killing germs. Researchers also found that washing even for 10 seconds significantly removed bacteria from the hands.”People need to feel comfortable when they are washing their hands but as far as effectiveness, this study shows us that the temperature of the water used did not matter,” said Donald Schaffner, professor at Rutgers University in the US. In the study, high levels of a harmless bacteria were put on the hands of 21 participants multiple times over a six-month period before they were asked to wash their hands in 60-degree, 79-degree or 100-degree water temperatures using 0.5 millilitre (ml), 1 ml or 2 ml volumes of soap.

While the study indicates that there is no difference between the amount of soap used, more work needs to be done to understand exactly how much and what type of soap is needed to removeharmful microbes from hands, researchers said. “This is important because the biggest public health need is to increase hand-washing or hand sanitising by food-service workers and the public before eating, preparing food and after using the restroom,” said Jim Arbogast, co-author of the study published in the Journal of Food Protection.

Those guidelines currently recommend that plumbing systems at food establishments and restaurants deliver water at over 37 degrees Celsius for hand-washing, they said. Schaffner said the issue of water temperature has been debated for a number of years without enough science to back-up any recommendation to change the policy guidelines or provide proof that water temperature makes a difference in hygiene.

Back in the day, royal dynasties were big believers in marrying “within the family” to keep bloodlines pure. Indeed, the practice was pretty commonplace among ruling families throughout Europe — even up to the last century.(That’s right: Great Britain’s Elizabeth II is the third cousin of her husband, Prince Philip.)Queen Elizabeth II and Prince Philip disembark from a British Airways Concord.But when it came to misguided procreation, the Spanish Habsburgs took the prize. No less than nine out of eleven royal marriages that were consummated during the years they were in power — from 1516 to 1700 — were incestuous. The reason behind the unbridled breeding? A bit of background.The Habsburgs, originally of German and Austrian descent, had been ruling various regions of Europe from the 1500s to the mid-1700s, when the dynasty endedThe Hapsburg family.The Spanish branch began when Philip I of Burgundy (a region which included parts of present-day Belgium, France, Luxembourg, and the Netherlands) tied the knot with Joanna of Castile, the female heir to the throne of what’s now a large portion of Spain, in 1496. That was the easy part. It would take decades of fierce fighting before Philp I could ascend to the throne in 1506.Concerned the crown that the family had fought so hard to attain might be taken away decades down the road, the Spanish Habsburgs decided to find spouses within their family to keep the monarchy intact.Charles V (1500 – 1558), Holy Roman Emperor from the Hapsburg HouseBeyond the obvious “ick” factor, there were serious repercussions that stemmed from the wanton inbreeding. For one thing, sixteen generations of incest lead to exceptionally high rates of miscarriages, stillbirths, and neonatal deaths (just half of the Habsburg children survived to the age of ten). And then there were the genetic defects that afflicted the family over the years.Most obvious was an unfortunate feature, which become known as the “Habsburg Jaw.” (In medical terms, a condition known as “mandibular prognathism,” characterized by a long chin and jutting lower jaw that creates a pronounced underbite, and sometimes an abnormally large tongue.)Philip IV of Spain.If bad enough, it can interfere with speech and can even make it difficult to fully close one’s mouth. Just a quick Google search of Habsburg family portraits reveals how the disfigurement progressed through generations.It’s said that when the first Habsburg ruler, Charles V, arrived in Spain in 1516, he couldn’t fully close his kisser, which prompted one smart-alecky peasant to shout, “Your majesty, shut your mouth! The flies of this country are very insolent.”Charles V of Spain’s Habsburg jaw.Charles II, the last Habsburg ruler of Spain, who took the throne in 1665, was equally doomed. Little wonder: His father, Philip IV, married his own sister’s daughter. (That made him Charles’s father and great-uncle.)Cruelly nicknamed El Hechizado (Spanish for “the hexed one”), Charles had a lower jaw so pronounced he struggled to speak -— or at least be understood — or even eat solid food, and his oversized tongue caused him to drool.Portrait by an unknown painter of Charles II in his later years.He was also short, lame, impotent and mildly retarded (he didn’t speak until he was four and couldn’t walk until he was eight).A French ambassador who traveled to Spain to suss out the king for a potential marriage observed, “The Catholic King is so ugly as to cause fear and he looks ill.”Poor, ill-fated Charles was unable to produce heirs, which brought the Hapsburg rule to an end. He would die in 1700, just days before his 39th birthday.Charles II in his twenties.The Habsburg women would suffer the same fate as the men. However, in his book Danubia: A Personal History of Habsburg Europe, author Simon Winder points out, quite correctly, that the Habsburg males could at least conceal their deformities behind beards. Alas, the women were not as lucky.One of the most famous Habsburg femmes, Marie Antoinette, considered a beauty in her day, escaped the family curse…almost.The French queen reportedly had a “projecting lower lip,” which gave her a somewhat pouty, though not unattractive, appearance.Read another story from us: The Fateful Role Ravens Played in Cursing one of Europe’s Oldest Royal DynastiesThough it might be noted, the queen had an entirely different set of problems to contend with.
A classroom chart displaying what is thought to be the earliest known version of the periodic table of elements has been discovered in a University of St. Andrews chemistry lab. Experts have dated the chart, found in a storage area in the Scottish university’s School of Chemistry, as being printed between 1879 and 1886.A massive clean-up of the lab began in 2014. Dr. Alan Aitken was reportedly clearing out chemicals, equipment, and laboratory paraphernalia that had accumulated since 1968 when he found a fragile periodic table that flaked upon handling, says the University of St Andrews.Periodic Table washing treatment. Photo by University of St. Andrews“Suggestions that the discovery may be the earliest surviving example of a classroom periodic table in the world meant the document required urgent attention to be authenticated, repaired and restored,” said St. Andrews in a press statement.Russian chemist and inventor Dmitri Mendeleev made his famous disclosure on periodicity in 1869. The newly unearthed table was rather similar, but not identical to Mendeleev’s second table of 1871. However, the St. Andrews table was clearly an early specimen.Dmitri MendeleevThe St. Andrews statement said: “The table is annotated in German, and an inscription at the bottom left – ‘Verlag v. Lenoir & Forster, Wien’– identifies a scientific printer who operated in Vienna between 1875 and 1888. Another inscription – ‘Lith. von Ant. Hartinger & Sohn, Wien’ – identifies the chart’s lithographer, who died in 1890.”Working with the University’s Special Collections team, the University sought out advice from international experts following the table’s discovery in 2014. Following in-depth investigations, no earlier lecture chart of the table appears to exist.Mendeleev’s periodic table from his book ‘An Attempt Towards a Chemical Conception of the Ether’.Professor Eric Scerri, an expert on the history of the periodic table based at the University of California, Los Angeles, dated the table to between 1879 and 1886 based on the represented elements. For example, both gallium and scandium, discovered in 1875 and 1879 respectively, are present, while germanium, discovered in 1886, is not.Prof David O’Hagan, former head of chemistry at St. Andrews, told the BBC: “The discovery of the world’s oldest classroom periodic table at the University of St. Andrews is remarkable. The table will be available for research and display at the university and we have a number of events planned in 2019, which has been designated international year of the periodic table by the United Nations, to coincide with the 150th anniversary of the table’s creation by Dmitri Mendeleev.”St. Andrews University. Photo by rob bishop / St Andrews University CC BY-SA 2.0Every effort is being made to preserve the chart.St. Andrews said, “In view of the table’s age and emerging uniqueness it was important for the teaching chart to be preserved for future generations. The paper support of the chart was fragile and brittle, its rolled format and heavy linen backing contributed to its poor mechanical condition. To make the chart safe for access and use it received a full conservation treatment.”Dmitri Mendeleev in 1897.Mendeleev was born in a village in Siberia. He made many contributions to science.A fellow scientist said of him: “A chemist of genius, first-class physicist, a fruitful researcher in the fields of hydrodynamics, meteorology, geology, certain branches of chemical technology (explosives, petroleum, and fuels, for example) and other disciplines adjacent to chemistry and physics, a thorough expert of chemical industry and industry in general, and an original thinker in the field of economy.”Mendeleev found that, when all the known chemical elements were arranged in order of increasing atomic weight, the resulting table showed a recurring pattern, or periodicity, of properties within groups of elements.Read another story from us: Mysterious Canines in Texas have DNA of Red Wolves – Thought to be ExtinctIn his 1871 version, he left gaps in places where he believed unknown elements would find their place. Mendeleev predicted the likely properties of three of the potential elements. The subsequent proof of many of his predictions within his lifetime brought fame to Mendeleev as the founder of the periodic law.
Advertisement In Game 3 of the Western Conference Finals last night, the Thunder humiliated the Warriors 133 – 105. The Warriors trail in the series 2 -1. The Warriors now await the NBA league office’s decision whether Draymond Green will be suspended for Game 4 for his viral low blow on Thunder Center Steven Adams in the second quarter.Green’s now infamous groin kick has been seen on social media on a continuous loop in GIF and Vine form since it happened. The debate is raging whether he should be suspended.After the game, Green told reporters the shot wasn’t intentional. The media and fans appear to largely disagree. In The Herd today, Colin said Green shouldn’t be suspended. He gave two primary reasons:1.) It’s very hard to prove intent. Green probably kicked Adams intentionally, but no one can prove it. 2.) Steven Adams wasn’t severely hurt and won’t miss the next game.The Green kick on Adams happened while the two big men were battling in the post. Post play in the NBA is physical by nature. Contact is expected. The kick may have been intentional, but it occurred where a lot of physical contact is common.If Russell Westbrook gets his legs taken out while attempting a dunk on a fast break, it’s different. That type of contact for a perimeter player isn’t common in the flow of the game. There’s also a risk of serious injury.If Green kicked a star player, as opposed to a marginal player like Adams, Colin would favor a suspension.“There’s a difference between robbing a 7-11 and robbing a bank. Robbing a bank is a federal crime, and kicking Steven Adams is different than kicking Kevin Durant if he continued to play, but wouldn’t be the same player in the series.”Former NBA league executive Stu Jackson joined The Herd today to discuss the Green incident. Jackson served as the NBA Vice President of Basketball Operations from 2007 to 2013. His responsibilities as Executive VP included handing down player discipline and suspensions.He went inside the NBA’s internal decision making process in levying suspensions. Jackson said the ultimate decision regarding Green will be made by NBA Commissioner Adam Silver. His decision may differ from the the recommendations of league executives.He recalled instances where former NBA commissioner David Stern vetoed his recommendations for punishment.“Most times I would take a recommendation to David Stern, and he would say, ‘Yes, let’s go with it, just tell me when it’s going to be announced.’ In case he needs to respond. But there were those times he would basically tell me over the phone ‘Are you out of your mind?’ I would respectfully respond and tell him all of the reasons why I arrived at the decision, and he would say, ‘We’re not doing that.’”In making the ultimate decision regarding Green, Commissioner Silver has to consider more than the act, including sponsors and television contracts. Jackson noted, “A commissioner of a professional sports league has many other things to consider other than the world of discipline on the floor. It’s his right to do that. He has to weigh his concerns from a broadcast standpoint against what the rules are.”
It’s been a rough year for Louisville basketball with the unexpected firing of former head coach Rick Pitino in connection with the ever expanding pay for play scandal. They took another gut punch last night in an improbable loss to Virginia in ACC play.With the Cardinals leading by by 4, 66-62 with .9 seconds left in the game, Virginia’s Ty Jerome was fouled shooting a three and made two of his three free throws. On the ensuing in bounds, Louisville turned it over on an inbound violation, giving UVA one last chance.With .9 seconds still on the clock, DeAndre Hunter banked in a buzzer beater three to cap the improbable comeback. Virginia deserves credit, but Louisville blew this one in epic fashion.Watch the unraveling:
Intel Corp agreed to buy Altera Corp for $16.7 billion as the world’s biggest chipmaker seeks to make up for slowing demand from the PC industry by expanding its line-up of higher-margin chips used in data centers.By combining with Altera, Intel will be able to bundle its processing chips with the smaller company’s programmable chips, which are used, among other things, to speed up Web-searches.Intel said on Monday it would offer $54 per share for San Jose, California-based Altera, a 10.5 percent premium to Altera’s close on Friday.Altera’s shares were changing hands at $51.83 in early trading, while Intel’s were up marginally at $34.48.The deal price is unchanged from Intel’s unsolicited offer that sources had said Altera rejected in April.The transaction is the third big one in the highly fragmented chip industry this year. In the industry’s biggest-ever deal, Avago Technologies Ltd agreed last week to buy Broadcom Corp for $37 billion.Altera’s programmable chips will allow Intel to increase the computational capability of its Xeon server chips, which could be under attack post the Avago-Broadcom merger, Summit Research analyst Srinivasan Sundararajan told Reuters.NXP Semiconductors NV set off the latest round of deals in March when it agreed to buy Freescale Semiconductor Ltd for $12 billion.Beyond PCsIntel’s deal for Altera is its biggest since it bought security software maker McAfee in 2011 for $7.7 billion.It also underscores Intel Chief Executive Brian Krzanich’s determination to expand beyond chips for PCs, the company’s mainstay. Intel slashed nearly $1 billion from its first-quarter revenue forecast in March, saying that small businesses were delaying upgrading their computers.Personal computer shipments fell 5.2 percent in the first three months of this year, extending three years of decline, according to research firm Gartner.Net revenue from Intel’s PC group increased just 4 percent in 2014, generating about 62 percent of total revenue, while revenue in its data center group increased 18 percent, providing just over a quarter of overall revenue.The deal will also help Intel become more involved in the so-called Internet of Things – the concept of connecting ordinary household devices to the Internet.The New York Post reported on Thursday that Intel and Altera had restarted talks.Up to Friday’s close, Altera’s shares had risen 41.3 percent since the Wall Street Journal reported on March 27 that the two companies were in talks. Intel’s shares rose 14.6 percent.J.P. Morgan Securities LLC and Rothschild Inc are financial advisers to Intel.

Set different virtual desktop wallpapers on Windows 10 by Martin Brinkmann on August 25, 2016 in Software – Last Update: July 05, 2017 – 4 commentsMicrosoft implemented native virtual desktop support in the company’s Windows 10 operating system that allows users to use multiple virtual desktops to divide programs on to them.The feature is not entirely new though, not even on Windows, as Microsoft offered a program called Virtual Desktop Manager for its Windows XP operating system.The functionality has not changed much since then, and the core difference is that the new implementation is native which means that users don’t have to install software to use virtual desktops on their computer.But the native implementation is rather limited when it comes to what you can do with it. You cannot set different wallpapers for each desktop for instance, and there is no option to select to load a different desktop on system start.Virtual Desktop EnhancerVirtual Desktop Enhancer is a free program for Windows 10 that extends the functionality of Microsoft’s virtual desktop implementation. It leaves the core functionality untouched, but adds features to it that users may find useful.Some of the features become available right away. You may use the keyboard shortcuts ALT-0 to ALT-9 for instance to switch between virtual desktops.While Windows 10 supports shortcuts by default, it does not switch with shortcuts to open a particular virtual desktop right away.Windows-Tab opens Task View that you may use to switch between virtual desktops.Windows-Ctrl-Left and Windows-Ctrl-Right switches to the previous or next virtual desktop.Windows-Ctrl-D creates a new virtual desktopWindows-Ctrl-F4 closes the active virtual desktopSo, the new Alt-key combination enables you to switch between desktops quickly, which is beneficial if you use more than two. The shortcut is easier to use also on top of that, so that it may work out better for you even if you only use one or two.Another feature that the program adds to Windows 10 is that it displays the number of the active virtual desktop in its icon. You may need to configure Windows to display that icon at all times though before that becomes useful.The two features that are not available right away are setting different desktop wallpapers for each virtual desktop, and selecting the start desktop that gets loaded when you boot Windows.Both options are only configurable in the settings file that sits in the program’s root directory. Open it in a plain text editor, and edit the features under General or Wallpapers.To switch the desktop that gets loaded on start, simply change the number after DefaultDesktop= to its number.Wallpapers are a different beast though. You may add solid colors using hex codes by using this format: 0xFF0000You may also add paths instead that point to local images which will then be loaded as the wallpaper for the selected virtual desktop.The program is offered as an exe file that you can run, or as an AutoHotkey script that you may run if you have the software installed on your device.You may check out the official thread on Reddit for further guidance and direct feedback.|Closing WordsIf you work with Windows 10’s native virtual desktop feature, you may find Virtual Desktop Enhancer useful as it adds several to the bare bones functionality of the feature.Some users may prefer third-party alternatives that offer better functionality than Windows 10’s native integration. There is nSpaces for instance which offers features such as password protection, Dexpot, and a whole array of other virtual desktop managers.Now You: Do you use virtual desktops?Summary12345 Author Rating4 based on 8 votes Software Name Virtual Desktop EnhancerOperating System WindowsSoftware Category PersonalizationLanding Page https://github.com/sdias/win-10-virtual-desktop-enhancer/releases Advertisement
