Scientists make holograms of atoms using electrons

first_img The scientists, Ymkje Huismans from the FOM-Institute AMOLF in Amsterdam, The Netherlands, and an international research team have published their study in a recent issue of Science Express.“What we have experimentally demonstrated is that it is possible to make holograms by taking an electron out of a molecule and, using a laser field, redirect the electron toward the molecule,” coauthor Marc Vrakking, of the FOM-Institute AMOLF and the Max Born Institute in Berlin, told PhysOrg.com.In their experiments, the scientists beamed an intense infrared laser light at an atom or molecule, which resulted in the atom or molecule becoming ionized and releasing an electron. The laser field causes the liberated electron to oscillate away from and toward the ion. Sometimes, an electron and ion collide, releasing a very short burst of radiation. Because the electron motion is fully coherent, meaning it always has the same phase, the scientists realized that they could apply holographic techniques to record information about the ion and electron. The key to holographic electron imaging is to observe the interference between a reference wave (which is emitted by the electron and doesn’t interact with the ion) and a signal wave (which scatters off the ion and encodes its structure). When the reference wave and signal wave interfere on a detector, the encoded information about the electron and ion is stored and can be viewed in the future. As the scientists explained, the result is a hologram of an atom produced by its own electrons.The researchers also developed theoretical models to simulate their measurements, confirming that the hologram had stored spatial and temporal information about the electrons and ions. By using the holographic structures to develop a new kind of ultra-fast photoelectron spectroscopy, researchers could be able to directly measure electron and ion movements on the attosecond timescale. This ability would be useful for understanding chemical reactions at the most basic level, particularly in molecules that cannot be easily studied by other methods. Scientists track electrons in molecules (PhysOrg.com) — While holography is often associated with artistic 3D images, it can also be used for many other purposes. In a new study, scientists have created holograms of atoms using laser-driven electron motion, which could lead to a new type of ultra-fast photoelectron spectroscopy. In the future, this type of holography could enable scientists to study the structures of molecules in a more direct way than before. This velocity map image shows the velocity distribution of ionized electrons, which are used to create a hologram of a Xenon atom. Image credit: Y. Huismans, et al. ©2010 Science.

Explore further Journal information: Nature Photonics More information: On-chip quantum interference between silicon photon-pair sources, Nature Photonics (2013) DOI: 10.1038/nphoton.2013.339AbstractLarge-scale integrated quantum photonic technologies will require on-chip integration of identical photon sources with reconfigurable waveguide circuits. Relatively complex quantum circuits have been demonstrated already, but few studies acknowledge the pressing need to integrate photon sources and waveguide circuits together on-chip8, 9. A key step towards such large-scale quantum technologies is the integration of just two individual photon sources within a waveguide circuit, and the demonstration of high-visibility quantum interference between them. Here, we report a silicon-on-insulator device that combines two four-wave mixing sources in an interferometer with a reconfigurable phase shifter. We configured the device to create and manipulate two-colour (non-degenerate) or same-colour (degenerate) path-entangled or path-unentangled photon pairs. We observed up to 100.0 ± 0.4% visibility quantum interference on-chip, and up to 95 ± 4% off-chip. Our device removes the need for external photon sources, provides a path to increasing the complexity of quantum photonic circuits and is a first step towards fully integrated quantum technologies.center_img In the quest to create a truly useful quantum computer, researchers focus on single areas of research that in the end can hopefully be taken together to reach the ultimate goal. In this new effort, the researchers sought a way to allow for observation of quantum interference on a single chip, and report that they have succeeded by creating what some have described as the most complex quantum circuit ever made.To allow for observing quantum interference, scientists have discovered, two virtually identical photons are needed, which means they need to be produced from two identical photon sources—no easy feat, but not impossible as the researchers have proven.The researchers built a chip that is able to accept a laser beam pumped directly into it—that beam is used as the basis for forming photon pairs by means of interaction with a piece of silicon. The quantum light produced was then combined using a beam splitter (which was also integrated into the chip). The path length of the photon beams was controlled by modifying the temperature of the waveguides which allowed for observing two-photon quantum interference. The team reports observations of “up to 100 ± 0.4% visibility quantum interference on-chip up and up to 95 ± 4% off-chip.”The team suggests their apparatus (basically, a quantum system on a chip) makes unnecessary the need for external photon sources creating a path towards a true quantum computer. They also note that what they’ve created has been achieved without resorting to reinventing fabrication methods—their system can use methods very similar, they say, to those for other CMOS devices, making bulk production relatively easy. They also suggest their device could very well pave the way to multiple photon pair sources which if developed to work together could allow for the construction of highly efficient devices.The team next plans to scale up their chip to allow for adding quantum processing tasks. (Phys.org) —A team made up of researchers from several countries has succeeded in creating a chip that allows for observation of the interference between silicon photon-pair sources. In their paper published in Nature Photonics, the team describes the nature of their chip, how it works and ways it might be used.

Bumblebees found to do better in urban settings than in agricultural areas

first_imgCredit: CC0 Public Domain Journal information: Proceedings of the Royal Society B Bumblebees are generally considered to be one of the friendlier bees that people encounter. Despite their large, round size, they tend to elicit less fear due to their non-threatening behavior. And according to a study done by the team in Britain, they also appear to find more success in urban areas than they do in agricultural areas. They came to this conclusion by conducting an extensive field study.The study consisted of capturing queen bees in a local park and putting them into nest boxes where they laid eggs. The nest boxes were then placed at 38 sites between Basingstoke and London and monitored for approximately 10 weeks—the average lifespan of a bumblebee colony. Each colony received a visit once a week—at night when all members would be present. During each visit, the researchers counted all members of the colony and noted how much nectar and pollen had been stored. They also removed cuckoo bumblebees (other bee species that lay their eggs in bumblebee colonies) and gynes (males capable of reproducing).The researchers found that that bumblebee colonies in cities produced far more males and gynes than did those in agricultural areas. They also found that both city and village colonies had much higher populations than the agricultural colonies. Those colonies located in agricultural areas also tended to have more cuckoo bumblebee invasions.The researchers were not able to say for sure why the bumblebees appeared to do better in urban and village settings, but suggest it could be due to a variety of factors. Agricultural areas tend to have crops that only bloom for a short time, they note, and which are exposed to pesticides and other toxic chemicals. Cities and villages, on the other hand, have a wide variety of flowers that bloom at different times.

Samuelson et al. Lower bumblebee colony reproductive success in agricultural compared with urban environments, Proceedings of the Royal Society B: Biological Sciences (2018). DOI: 10.1098/rspb.2018.0807AbstractUrbanization represents a rapidly growing driver of land-use change. While it is clear that urbanization impacts species abundance and diversity, direct effects of urban land use on animal reproductive success are rarely documented. Here, we show that urban land use is linked to long-term colony reproductive output in a key pollinator. We reared colonies from wild-caught bumblebee (Bombus terrestris) queens, placed them at sites characterized by varying degrees of urbanization from inner city to rural farmland and monitored the production of sexual offspring across the entire colony cycle. Our land-use cluster analysis identified three site categories, and this categorization was a strong predictor of colony performance. Crucially, colonies in the two clusters characterized by urban development produced more sexual offspring than those in the cluster dominated by agricultural land. These colonies also reached higher peak size, had more food stores, encountered fewer parasite invasions and survived for longer. Our results show a link between urbanization and bumblebee colony reproductive success, supporting the theory that urban areas provide a refuge for pollinator populations in an otherwise barren agricultural landscape. © 2018 Phys.org This document is subject to copyright.

Genderbased colours in toys can spur harmful stereotypes

first_imgToymakers should avoid gender- labelling toys, and create items for both boys and girls in a wide range of colours, say scientists who found that children’s perception of what is appropriate for a gender can be easily manipulated. The study is also the first to show that a boy’s liking of blue and a girl’s preference for pink is not just a Western construct, but is also a phenomenon in urban Asian societies.The researchers from University of Hong Kong recruited 129 Chinese children aged between five and seven from two kindergartens in Hong Kong. Also Read – Add new books to your shelfFirst they assessed the children’s preference for pink versus blue by showing them cards and toys in these colours.Then the children were presented with yellow and green cards and toys.They were randomly divided into so-called label and no-label groups.Children in the no-label group were presented with coloured cards and toys which had no reference to a specific gender and these children consequently expressed no preference for a specific colour.However, preschoolers in the label group were told that yellow was a girl’s colour and green a boys’ colour, and corresponding gender differences emerged in the choices they made. Also Read – Over 2 hours screen time daily will make your kids impulsive Apart from randomly assigning children to these two groups, the children’s pre-existing preferences for yellow and green were statistically controlled, so the resulting difference between the groups speaks strongly to a causal effect of the gender labels.According to the researchers, the gender differences between preferred colours in children is noteworthy because it is so much more prominent than most other psychological differences between the sexes. “Our findings support the notion that gender-typed liking for pink versus blue is a particularly salient gender difference,” said Sui Ping Yeung from University of Hong Kong.”Moreover, our findings reveal that gender differences could be created merely by applying gender labels,” Yeung said.The findings, published in the journal Sex Role support previous research that highlighted the strong influence that gender labels such as “for boys” or “for girls” might have. Further, the observations are in line with gender schema theory that says that once children have learnt a specific gender identity, their behaviour will be guided by the standards set as being appropriate for their specific sex.These will guide them later in life on how they interact and adapt to their surroundings, for instance, when taking on chores around the house, such as cooking, cleaning or repairing things.last_img read more

Importance of skincare for men

first_imgIt’s not only women who need skincare products to maintain their skin and avoid future problems such as wrinkles, acne and roughness, men too need the right treatment for their skin. Using organic face oils and under eye creams can do the trick.Experts talk about the importance of men’s skin care:4Men’s skin is generally oilier than that of majority of women which leads to acne issues. Hence, using face gels helps to prevent the same and is highly recommended. Facial gels also help you avoid pigmentation and blemishes. Also Read – Add new books to your shelf4Men’s skin has a tougher tone and dark patches as they shave regularly. Just using an after shave is not enough. Again, using a simple facial gel or organic face oils post a shave is highly recommended. 4Men with their their stressful work regime are prone to puffy eyes and eye bags that can be cured by under eye creams made specifically for their harsh skin. 4It is a known fact that their skin tans easily as compared to women and hence using day creams with SPF is a must for men on a daily basis. This is not a cosmetic procedure but simply a health measure for the skin. 4 Men’s skin needs hydration too. Skin dehydration is a major problem that leads to breakouts and dry patches. Hydrating sheet masks are the solution to this common issue. Using sheet masks may sound feminine but are made for men too. These are an important night routine to let the skin breath and avoid dryness.last_img read more

Elon Musks Las Vegas Tunnel Plans Are Worrying Monorail Officials

first_img 3 min read Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right. This story originally appeared on Engadget August 2, 2019 Planning documents, obtained by TechCrunch, are revealing much about how Elon Musk’s proposed Las Vegas loop would work. The Boring Company is charged with building three tunnels: one for pedestrians and two for passenger “sleds,” stretching across the Las Vegas Convention Center Campus. The two vehicle tunnels will be filled with a fleet of autonomous Tesla-based EVs that can carry up to 16 people at a time.There are concerns, however, that the tunneling work required to build Musk’s loop is running too close to the adjacent Las Vegas Monorail. As TechCrunch reports, Monorail officials have lobbied for more oversight and raised objections over tunnels running close to the Monorail’s support pillars. Given the tight tolerances involved, it’s likely that a small amount of disruption could shut the elevated railway down.The Las Vegas Convention Center is a sprawling complex with around 3.2 million square feet of exhibit space across its numerous halls. In short order, a new building, with an additional 1.4 million square feet of space will be added, with construction underway on Elvis Presley Boulevard. That expansion — dubbed “Phase Two,” is expected to open in 2023, followed by an expensive renovation of the existing buildings.If you wanted to talk from the front door of the South Hall to the new building, you’ll be traveling almost a full mile. That half-hour walk each way is hardly ideal for trade show visitors trying to cover so much ground in a short space of time. And so the organization began looking for people movers that could shrink that distance, with Musk’s loop standing out as an early contender.The plans suggest a route that runs from the Phase Two building, through the central parking lot of the LVCC, ending at the back of the South Hall. At ground level, small subway-like entrances would filter down to a mezzanine, below which you’d find the two platforms. What isn’t clear, right now, is how the pods would get out of each other’s way when they reach the terminus at each end with no turning space.At this point, the suggestion is that the self-driving passenger sleds will be based on Tesla’s electric vehicles. But according to comments made Boring Company official Jane Labanowski, these vehicles will have a human driver, or at least an operative. That’s likely to increase the price and cost of riding, at least if things don’t change between now and the proposed project deadline of January 2021.These preliminary documents are clearly not exhaustive architectural plans, and so we can’t draw too many conclusions from them. But, if the system is as simple as a manned Tesla vehicle running through a tunnel, then the finished project could be quite underwhelming. And expensive, compared to the cost of, say, simply marking one of the nearby roads exclusively for shuttle buses that go back and forth between the halls.

Meteor mobile and app speed test for Android

first_imgMeteor: mobile and app speed test for Android by Martin Brinkmann on March 03, 2017 in Google Android – Last Update: March 03, 2017 – No commentsMeteor – App Speed Test is a free application for Google Android devices that tests the mobile connection speed and indicates how well popular apps will run with those speeds.Most mobile benchmark applications do the same thing: they test the ping, upload and download speed, and may use several servers for that located in different regions of the world.While that is great for a quick rundown on the devices connectivity at that point in time, the usefulness of many of these benchmark applications ends there.Meteor – App Speed Test reviewMeteor – App Speed Test is a great looking benchmark application for Android. It looks like any other app of its kind on start — if you forget about the design for a moment — but you will notice that it has more to offer quickly.Note: the application shares anonymized signal and speed data with OpenSignal. You can disable that with a tap on Menu > Settings, and a tap on the on/off button next to data contribution.First thing though is the usual speed test. Meteor tests the download and upload speed of the mobile connection, and the ping to a nearby server. The results are listed in the application’s interface afterwards.You find the new app performance section listed on the same page after the speed test. There you find listed popular applications, YouTube, Spotify, Facebook, Waze and more, and how they will perform under the given network conditions.Not all of the apps are installed necessarily on the device. In fact, you may get the same apps listed even if none of them are installed on the device. You may add more apps however from a list of 16 apps. The additional apps include Chrome, WhatsApp, Twitter, Amazon, or Skype to name a few.The app highlights the projected performance, e.g. very good or awesome, right there on the test results page. You may tap on any application name however to display detailed information.If you tap on YouTube for instance, the performance for several of the video streaming site’s stream qualities are listed there so that you know which work well, and which may not work as well. This can be useful if you want to know if one of the supported applications, and one of the quality options of a given application, works when the device is connected to the network you tested.The application displays tests on a world map, and as a history. You can check those out at any time.Other benchmarking apps for Android that you may be interested in are Network Tester, 3D Mark, or GeekBench.Closing WordsMeteor – App Speed Test is a great looking application for Android that lets you run connection benchmarks, and informs you about how well certain apps and quality settings of those apps will work under those network conditions.Now You: Do you run speed tests to benchmark network performanceSummary12345 Author Ratingno rating based on 0 votes Software Name Meteor – App Speed TestOperating System AndroidSoftware Category InternetLanding Page https://play.google.com/store/apps/details?id=meteor.test.and.grade.internet.connection.speed&hl=en Advertisementlast_img read more

Keep antigay law Section 377A urges Singapores Catholic Church

Moreover, He suggested it would lead to further demands for equal marriage or same-sex adoption. ‘I pray that we will not walk the slippery path of no return’, the Archbishop wrote.‘Will the Church be forced to accept the promotion of homosexual values and lifestyles in our schools?’ he asked. And ‘let transgender persons use bathrooms for those of the opposite sex’.Debate continuesThe incendiary remarks come as debate over Section 377A continues to rage in the city-state.More than 40,000 LGBTI rights supporters have signed an online petition to repeal the law. Meanwhile, about 100,000 people have signed a petition maintain the rights-abusing law.A Singapore disk jockey filed a legal challenge against Section 377A of the city-state’s Penal Code last week.

Gran Solaris hotel project at Cancun Hotel Zone temporarily suspended

first_imgCancun, Q.R. — After weeks of protests, the mayor of Cancun has agreed to suspend the hotel construction project at Playa Delfinis until all paperwork is reviewed.The municipal president of Benito Juárez, Remberto Estrada Barba, clarified that the suspension of the Gran Solaris Cancún project is the result of an appeal for review filed by two councilors and does not represent in any way, a sanction to the developer Villas Solaris S de RL de CV.The mayor pointed out that his decision to suspend the project also derives from the dissatisfaction of citizens regarding the hotel project that, if built, would consist of 450 rooms within a lot of 18,844.31 square meters located next to Playa Delfines at kilometer 19.5 of Boulevard Kukulcán.He specified that the constancy of land use and the construction license, both issued by the Municipal Department of Ecology and Urban Development (SMEyDU) of Benito Juárez, will be verified.“It is not a sanction. It is simply a review filed by two councilors of this Honorable Cabildo for a review of the land use and the construction license that was issued at the time. The review will be to thoroughly verify each of the processes that have been given, while emphasizing that we are listening to the request of many citizens,” he said.He said that his government is in favor of investment through real estate development, however, he stressed that it has to be sustainable and legal.“Effectively we continue arguing that we are in favor of construction, of development, as long as it is compatible with sustainable development and as long as it complies with all current regulations, existing in each of the laws,” he said.The government of Remberto Estrada insisted that there is no ecological damage by the project, and that they will monitor both the work and the project so that it in no way affects the integrity, access and services of Playa Delfines, which is and will continue to be public.He explained that “any investment project that complies with the legal framework and respects the environment, is welcome to Cancun for the benefits it generates in economic, employment and greater attraction of tourists.”He specified that in recent dates, “Some sectors have been expressing concerns and doubts about the Gran Solaris and that a lot of information has been spilled, some inaccurate, some partial and out of context, and a part totally alien to the truth.”City Council stated that to clear up doubts, they decided to request a suspension of the construction license in order to review the status of the project.In a statement, the city said “We believe it is appropriate for the authority to review again, and in detail, the municipal authorizations and their due compliance by the individual, as an exercise of transparency for the benefit of all.”He clarified that this suspension should not be taken as the closure of the project, since if it is confirmed that the project is in compliance with the law, the suspension will be lifted and the work will continue.City Council says the hotel is set for review on December 13.Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on WhatsApp (Opens in new window)last_img read more
