Image: TechOn AR systems present a real field of view of a physical environment augmented by computer-generated imagery (CGI), thus combining the real world with the virtual. They are often interactive in real time and sometimes the images are three-dimensional. In Japan AR technologies are finding their way into digital signage applications and store windows, showcasing products and giving shoppers additional information on products. One example is Toppan Printing Co. Ltd., which has been testing a terminal resembling a vending machine in three Ito-Yokada supermarkets. In this system potential shoppers register on the Toppan website and receive a QR (Quick Reference) code. (The QR code is a relative of the barcode but consists of a pixilated rectangle rather than stripes.) The shopper presents the code to a camera on one of the terminals in the store, and then receives a sample product. When the sample product is held in front of the camera the terminal displays an image of the product with the description superimposed upon it.Furutanisangyou Co. Ltd. is using a non-real-time AR technology in a “Magical Mirror” system that allows shoppers to see how outfits would look on them without needing to try them on. A similar system, the “Virtual Mirror,” was demonstrated in the CEATEC JAPAN 2009 trade show in Tokyo by Germany’s Fraunhofer Institute.The Magical Mirror has a number of cameras, one of which captures an image of the shopper, which is then displayed on a high definition LCD. Images of selected clothes are then superimposed on the image of the person, with the system processing the digital images to make them fit the person’s image. The clothes shown in the composite image are available for sale in stores in the underground shopping mall where the system is located, and the image includes information on where the clothes can be purchased and what sizes are available. The Magical Mirror allows a shopper to “try on” up to six different items of clothing at the same time, even if they are sold at different locations, and this allows the shopper to see how combinations of clothes would look together before buying any of the items. “Magical Mirror.” Image: TechOn
Journal information: New Journal of Physics As the researchers explained, they intentionally removed the equal volumes constraint when developing their search method because it allowed them to design the algorithm in a new way: instead of directly minimizing the surface area of a structure, they maximized the polyhedra’s average isoperimeters (the perimeters shared by all adjacent polyhedra). While these two approaches are different, they are ultimately equivalent.The researchers used the new algorithm to explore several 3D structures made of between two and 64 polyhedra. Starting with a specific number of randomly arranged points in 3D space, the algorithm begins to move the points around. After each iteration, the algorithm calculates the new average isoperimeter, and based on the result either keeps or rejects the new configuration with a certain probability. After millions and sometimes billions of iterations, the points eventually form the vertices of multiple polyhedra that together form a 3D structure with very low surface area.As there is currently no way to prove what the most optimal space-partitioning structure is (with or without equal-volume cells), the researchers plan to continue searching a wide variety of structures of all types. Their best guess is that even more optimal structures exist, and they plan to use their algorithm to continue their exploration.The researchers also expect that the algorithm could generate other unique structures. One particularly interesting structure they discovered here is a 40-polyhedra structure that is more optimal than Kelvin’s structure but not quite as good as the Weaire-Phelan structure. This highly complex structure is also unusual in that it doesn’t belong to a category of structures called Frank-Kasper structures, which researchers have traditionally focused on for optimal space partitioning. The finding suggests that other optimal structures may also exist outside of this category. Although Kelvin’s problem wasn’t originally proposed to meet any practical need, optimal space partitioning now has a variety of applications. In the medical field, these concepts have been used to design strong, lightweight bone tissue replacements. Optimal space partitioning has also inspired architecture, with one notable example being the swimming venue built for the 2008 Beijing Olympics. The building, which is called the Water Cube, is based on the Weaire-Phelan structure.

Credit: Opsomer and Vandewalle. ©2016 IOP Publishing In 1887, Lord Kelvin asked how space could be partitioned into 3D structures of equal volume in a way that minimizes the total surface area of each structure. It must be possible to tightly pack many of these structures together with no gaps in between them—in other words, they must be “space-filling” structures. Each structure can take on a variety of complex 3D shapes, or “polyhedra,” either as a single polyhedron or a combination of multiple smaller polyhedra of various types. The challenge is to figure out what particular types of polyhedra to use in order to minimize the outer surface area of the entire structure. Kelvin’s best solution to this problem was a single polyhedron called a “tetrakaidecahedron,” which has 14 faces: six squares and eight hexagons. Since this is the shape obtained when cutting the corners off a 3D diamond shape, it can also be thought of as a truncated octahedron.Although Kelvin’s solution stood for more than a century, in 1994 Denis Weaire and Robert Phelan at Trinity College Dublin used numerical simulations to discover a more optimal space partition. Weaire and Phelan’s solution is made of eight polyhedra of two different types, though both types have the same volume: six of Kelvin’s tetrakaidecahedron and two dodecahedron (which has 12 faces). Together, these eight polyhedra make up a 3D structure that has 0.3% less surface area than Kelvin’s single tetrakaidecahedron. The Weaire-Phelan structure has remained the most optimal solution to Kelvin’s problem for the past 22 years. Now in the new study, physicists Eric Opsomer and Nicolas Vandewalle at the University of Liége in Belgium have developed a new algorithm for finding space-filling composite polyhedral structures with minimal surface area. Using the new method, they discovered that a novel 3D structure made of 24 polyhedra has an even lower surface area than the Weaire-Phelan structure. The 24 polyhedra are of two different types: some have 12 faces and some have 16 faces. Unlike the Weaire-Phelan structure, in which the two different types of polyhedra have equal volumes, the 12- and 16-faced polyhedra here have significantly different volumes. For this reason, the new structure doesn’t satisfy Kelvin’s original requirement for equal volumes. “Unfortunately, it is not a ‘true solution,’ since equal volume cells are a requirement for the original Kelvin problem,” Opsomer told Phys.org. Nonetheless, the structure is still interesting for other reasons. “These results may lead to the discovery of structures with potential implications for material physics, medical research, and other areas,” Opsomer said.

Patrick Semansky 70 Mayors Reject Trump Food Stamp Proposal, Saying It Puts… by NPR News Bobby Allyn 8.22.19 3:22pm The Trump administration’s proposal to push millions of people out of the federal food stamp program would punish some of the country’s neediest, including children, seniors and people with disabilities, according to mayors of 70 American cities who have sent a letter to an administrator for the Supplemental Nutrition Assistance Program.Under a new rule proposed in July by the Agriculture Department, more than 3 million people would lose their food assistance. The mayors say the move would also hurt their local and regional economies.The change to SNAP is aimed at plugging what critics say is a loophole that allows states to give benefits to people whose savings and other assets the Trump administration says should make them ineligible for food stamps.Anti-poverty groups view the shift as part of a broader push by the Trump administration to peel people off government assistance. Republicans who back the move say the new rules are needed to curb abuse of federal safety net programs.Through the change, the Trump administration aims to cut spending by some $2.5 billion a year. Agriculture Secretary Sonny Perdue has pledged the plan will also preserve “the integrity of the program.” But dozens of mayors counter that shaking up the eligibility requirements will exact a toll on some of the nation’s most vulnerable people.”This proposal will put children’s health and development at risk by removing their access to healthy school meals; and harm our economy by reducing the amount of SNAP dollars available to spur regional and local economic activity,” wrote the city leaders, in a letter sent from the U.S. Conference of Mayors.The mostly Democratic mayors who signed the letter come from around the country, from Fremont, Calif., to Houston and from Edina, Minn., to Philadelphia.”Our nation cannot remain globally competitive if our children do not have enough to eat; if our citizens do not have access to affordable health care; if housing and other basic needs are priced out of reach; and if adults who are willing and able to work cannot find jobs that will help them support their families,” the mayors wrote.The majority of the people who receive SNAP are children, the elderly or people who struggle with a disability. Government statistics show that the average monthly benefit per person is $135 a month.Federal food assistance is a pathway out of desperate circumstances, the mayors argue.”SNAP is not only a critical resource in the fight against hunger and food insecurity, but also lifts people out of poverty,” their letter states.Since the new federal rule has been open to public comment, more than 4,000 people have weighed in on the proposal, with many strongly opposing the Trump administration’s move.”It’s horrifying to think that millions of people will not have food stamps! I encourage the American government to act for the people that need a hand up from desperate situations,” wrote Kala Nyx.”I am a 55 year old white male from rural Texas,” wrote Johnny Dotson, who said he has known many families who have depended on SNAP. “You should be ashamed of yourselves if you believe it is ok to make children go hungry for ANY reason. You may think there will be so few children negatively affected it would be worth the cost, but you are wrong.”Others, like Joal Devendorf, embraced the Trump administration’s proposed move.”We should close loopholes such as the SNAP loophole. Temporary Assistance is fine; ongoing dependence is not,” he wrote.The mayors, meanwhile, are fretting about how the overhaul to food assistance will impact their regions’ local economies, saying those who receive benefits spend more money in their communities, as part of a “multiplier effect” that boosts overall economic activity, including job creation.Citing the USDA’s own statistics, the mayors wrote, “during times of economic downturn, every additional $5 dollars in SNAP benefits generates up to $9 dollars of economic activity.”The Agriculture Department did not immediately respond to a request for comment. The department can move forward with the new rule in about a month, after the 60-day public comment period ends on Sept. 23.Copyright 2019 NPR. To see more, visit NPR.

This is most unfortunate. Religion is private and in social life our only philosophy is to serve the people,” he added. Banerjee said the 2019 Lok Sabha election is “not a fight between Trinamool and BJP. It is a fight between Bengal’s rich tradition and culture on one side and the Centre’s extortion on the other.” Also Read – Lightning kills 8, injures 16 in stateHe alleged that BJP has looted the country in the past five years. “You will not hear a single word from them on note ban which was implemented to stop black money and terrorism. BJP does not say anything on the hasty implementation of GST either, along with farmer suicides and why 2 crore people lost their jobs. They only talk on religion to incite one community against the other,” the Trinamool Youth Congress president stated. Banerjee urged people to cast their votes in favour of party nominee Manas Bhuniya. “Undivided Midnapore had played a major role in the freedom movement. In 2019, the district will play a major role in driving out the Modi government. On May 23 when the ballot boxes will be opened, people will see that Trinamool Congress has bagged 42 out of 42 seats,” he said. He also urged people to visit the polling stations early and exercise their franchise.
Worried that your son or daughter sleep more even during final exams week? If so, take heart. According to a study, students who sleep for eight hours are more likely to perform better. “Better sleep helped in final exam performance, which is contrary to most college students’ perceptions that they have to sacrifice either studying or sleeping,” said Michael Scullin, Assistant Professor at Baylor University’s College of Arts and Sciences. Also Read – Add new books to your shelfFor improvement in academic performance, a student does not have to be an ‘A’ grade, the researchers said. The findings showed that whether a student was an A, B, C, or D student before their final exam, sleeping eight hours was associated with a four-point grade boost. “It is worth noting that one student who had a D-plus grade before the final but slept more than eight hours for a week during finals week remarked that it was the first time her brain worked while taking an exam,” Scullin said. Also Read – Over 2 hours screen time daily will make your kids impulsivePoor sleep is common during finals as students cut back on sleep, deal with more stress, use more caffeine and are exposed to more bright light, all of which may disrupt sleep. Fewer than 10 per cent of undergraduates maintain the recommended average of 8 hours a night or even the recommended minimum of 7 hours, the researchers said. In the study, the students were given extra points if they met “the 8-hour Challenge” – averaging eight hours of sleep for five nights during final exams week. The participants included undergraduate interior design students and students in upper-level psychology. They wore sleep-monitoring wristbands for five days for accurate results.
Making resolutions and scheduling actions for New Year is something that everyone aspires for. But, the real challenge is in keeping up the momentum to achieve the goals. Chaotic routines, dwindling will-power or plain laziness tend to succumb to these at some point or the other. However a few steps might help you to achieve the goals you have set for yourself in 2019. Experts list some ways to keep up with your New Year resolutions: Trick your brain and start by familiarising your mind with your resolutions by visualising them. Write down your goals and stick them at some corner you visit often like your bedroom walls or office cubicle. These work as perfect reminders which we often require. This will make you feel more inclined towards your goal without positioning it as a threat to your habits. Also Read – Add new books to your shelfRecharge your spirits and boost yourself with some pep talk by listening to self-help podcasts. When routine wears you down, escape it with motivational and inspirational sessions on podcast platforms. From health to career goals, you will find a countless number of topics on how you can set realistic goals and achieve them. Also, Set practical and achievable goals keeping in mind your budget. Ensure the goals are specific and measurable for example, ‘I want to lose 5 Kgs’ is a better-defined goal which you can work towards than ‘I want to have a figure like some Bollywood actress’.
