At Monday’s City of Fort St. John Committee of the Whole meeting, members of the North Peace Gymnastics Association made a presentation to City Council. Aside from talking about the role of the club within the community, the future of the organization was also discussed.The club is looking for a temporary facility where it can carry on its usual activities. In particular they would require a structure that has at least 4,000 square feet of gym space, although more would be preferable as programming was previously maxed out at 6,000.A ceiling height of 18 to 20 feet would be needed for safe use of a trampoline and uneven bars. Washrooms and changing rooms for male and female members would also be needed.- Advertisement -As for where things stand currently, the City admitted the fate of the gymnastics club gym is unknown as the insurance company has not reviewed the site. There is also no timeline as to when the process will be completed.“Does the City intent to rebuild or repair the building which housed the gymnastics club? I don’t think we know yet,” Mayor Lori Ackerman said. “I’m not sure if the insurance has even taken a look at things because a report has not come to Council yet.”Ackerman added the City will work with the gymnastics club as much as possible moving forward and will keep them informed once it’s determined what will happen to the gym, as well as potential temporary solutions.Advertisement
APTN National News HAMILTON–A group of protestors occupying an Enbridge pipeline pumping station near Hamilton have been served with a court injunction ordering them to leave the site.The group has been given two hours to vacate the premises, said Melissa Elliott, a Tuscarora woman from Six Nations who is acting as spokesperson for the protest.Elliott said the protestors, who have locked themselves to the gates of the station, are currently discussing their next move.“Those talks are happening right now,” said Elliott.The five-day long protest has stalled worked by Enbridge in their Westover terminal for phase one of their Line 9 project which aims to bring tar sands oil to the east.Protests in support of the Hamilton area action are also planned across the country Tuesday as part of the “Sovereignty Summer” campaign spearheaded by an alliance between Idle No More and the Defenders of the Land.Protests are planned in places like Vancouver, Edmonton, Sarnia and Toronto, along with other locations.

Ole Gunnar Solskjaer confirmed that Antonio Valencia will retain the captain’s armband at Manchester UnitedThe Ecuadorian full-back was officially named the United captain in the summer following Michael Carrick’s retirement from playing football.Although, amid struggles for form and fitness, Valencia’s place in the United team has been in doubt with just seven appearances across all competitions this season.But interim coach Solskjaer, who’s won both of his opening games in charge at United, made it clear that Valencia is still the skipper.Maguire says United need to build on today’s win George Patchias – September 14, 2019 Harry Maguire wants his United teammates to build on the victory over Leicester City.During the summer, Harry Maguire was referred to as the ultimate…“I told you he’s the captain and, when he’s properly fit and playing, he’ll wear the armband,” said Solskjaer on the club website.“He’s going through a couple of tough sessions now to get him ready for the busy period coming up.”When you look at Antonio, there are not many better right-backs going forward with his abilities so, yes, you’ll see him wearing his armband.“United will be taking on Bournemouth on Sunday at Old Trafford with Solskjaer hoping to make it three wins out of three.
Citation: Scientists reach milestone in 3-D laser writing in bulk silicon (2017, October 18) retrieved 18 August 2019 from https://phys.org/news/2017-10-scientists-milestone-d-laser-bulk.html Researchers fabricate 3-D silicon structures with a focused infrared laser More information: Margaux Chanal et al. “Crossing the threshold of ultrafast laser writing in bulk silicon.” Nature Communications. DOI: 10.1038/s41467-017-00907-8 Journal information: Nature Communications The researchers expect that the results will open the doors to 3D laser writing for silicon photonics applications, as well as for studying new physics in semiconductors.The scientists, Margaux Chanal et al., from institutes in France, Qatar, Russia, and Greece, have published their paper “Crossing the threshold of ultrafast laser writing in bulk silicon” in a recent issue of Nature Communications.In previous attempts at ultrafast laser writing in bulk silicon, scientists found that femtosecond lasers simply weren’t capable of structurally manipulating the bulk silicon, even when the laser energy was increased to the highest pulse intensity technologically possible. In the new study, the researchers found that, fortunately, there is no physical limit that prevents ultrafast laser-induced structural manipulations of bulk silicon. Instead, they found that the laser energy has to be delivered in the medium in an abrupt way in order to minimize losses from nonlinear absorption. This finding revealed that the problem of all past efforts arose from the laser’s small numerical aperture (NA), which refers to the range of angles over which focused laser light can be delivered. The researchers calculated that, in order to achieve the desired results, it would be necessary to obtain extreme NA values that have so far not been realized in this area.In order to reach these extreme NA values, the researchers borrowed a technique from advanced microscopy called solid-immersion microscopy. The idea is similar to the commonly used liquid-immersion microscopy, in which a small drop of oil is placed on the slide. As oil has a larger refractive index than air, the oil reduces the amount of optical refraction (bending of light) as the light travels between the slide and the microscope lens. This, in turn, increases the NA and the associated microscope’s resolution (the NA for a microscope measures the range of angles over which light is collected rather than delivered). The difference with solid-immersion microscopy is that a solid material with a high refractive index is used instead of a liquid. (Phys.org)—It has taken more than 20 years, but researchers have demonstrated for the first time that femtosecond lasers can be used to structurally manipulate bulk silicon for high-precision applications. Since the late ’90s, researchers have been using the ultrashort pulses of femtosecond lasers to write into bulk materials with wide band gaps, which are typically insulators. But until now, precise ultrafast laser writing has not been possible for materials with narrow band gaps, such as silicon and other semiconductors. © 2017 Phys.org This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. In the new study, the researchers used silicon spheres as the solid-immersion medium. They found that, when focusing the laser at the center of a sphere, they could completely suppress refraction and greatly increase the NA. The extreme NA values allowed the laser pulses to achieve sufficient ionization to break chemical bonds in the silicon, which in turn causes permanent structural changes in the material.”The in-depth understanding of the physics of the interaction and propagation of ultrashort laser pulses in low-band-gap semiconductors, like silicon, enabled us to solve this long-standing problem and achieve controlled material structural modifications, appropriate for applications,” coauthor Stelios Tzortzakis, at the Texas A&M University at Qatar, FORTH, and the University of Crete in Greece, told Phys.org. “Even more, the localized energy deposition in the medium results in out-of-equilibrium phases with extreme thermal and pressure gradients that can enable the creation and study of new states of matter, previously unreachable in laboratory environments.” In the future, the researchers plan to further push the boundaries of this approach by borrowing another microscopy technique called 4-Pi arrangement. This concept involves crossing multiple laser pulses with extreme NA values at the centers of spheres, which may lead to even greater possibilities in ultrafast laser writing in bulk silicon and other semiconductors.”3D laser writing applicable to silicon may drastically change how things are designed and fabricated in the important field of silicon photonics,” said coauthor David Grojo at CNRS/Aix-Marseille University in France. “Silicon photonics is seen as the next revolution of microelectronics using light at the chips level for ultimate speed data processing. However, it remains today a 2D world because of the planar lithographic methods used for fabrication (SOI technology). With our method we can envision the equivalent of a 3D printer for rapid prototyping of any innovative architecture. This will make possible for silicon photonics specialists to design things in 3D that must represent a real booster for the emergence of disruptive technologies and new concepts.” Experimental setup of using 60-femtosecond laser pulses for laser writing in silicon.

Researchers have found that practicing what is known as a “dual n-back” exercise can lead to improvement in working memory, which is what people rely on to temporarily hold details in their mind like phone numbers and directions. The “dual n-back” is a memory sequence test in which people must remember a constantly updating sequence of visual and auditory stimuli. The study published in the Journal of Cognitive Enhancement suggests it is possible to train the brain like other body parts – with targeted workouts. Also Read – Add new books to your shelf”People say cognitive training either works or doesn’t work. We showed that it matters what kind of training you’re doing,” said lead author Kara Blacker who was with Johns Hopkins University in Baltimore at the time of the research.”This one task seems to show the most consistent results and the most impact on performance and should be the one we focus on if we’re interested in improving cognition through training,” said Blacker, now a researcher at the Henry M. Jackson Foundation for Advancement of Military Medicine Inc in Maryland. Also Read – Over 2 hours screen time daily will make your kids impulsiveThe researchers decided to compare directly the leading types of exercises and measure people’s brain activity before and after training.First, the team assembled three groups of participants, all young adults. Everyone took an initial battery of cognitive tests to determine baseline working memory, attention and intelligence. Everyone also got an electroencephalogram (EEG) to measure brain activity. Then, everyone was sent home to practice a computer task for a month. One group used one leading brain exercise while the second group used the other. The third group practiced on a control task.The training programmes compared are not the commercial products available to consumers, but tools scientists rely on to test the brain’s working memory.Everyone trained five days a week for 30 minutes, then returned to the lab for another round of tests to see if anything about their brain or cognitive abilities had changed.The researchers found that the group that practiced the “dual n-back” exercise showed a 30 per cent improvement in their working memory. That was nearly double the gains made by the group working with the other common task, known as “complex span”. The dual n-back group saw squares flashing on a grid while hearing letters. They had to remember if the square they just saw and the letter they heard were both the same as one round back. As the test got harder, they had to recall squares and letters two, three and four rounds back. The other test, called “complex span,” also involves remembering items in a sequence, but they do not need to continually update the items in their mind.”The findings suggest that this particular task is changing something about the brain,” said study co-author Susan Courtney, Professor at Johns Hopkins University.

From brochures to invoices, color adds interest and gives you a professional edge. There are many routes you can take to add color to your printing options: inkjet, color laser, solid ink, personal printer or workgroup printer. For the most flexibility within your company, a networkable color printer is the ticket, and that usually translates to a color laser. We’re going to browse through a variety of colorful options, including a couple of multifunctions as well as a solid-ink offering from Xerox.The cost of running a printer is something to consider. The $1,759 (all prices street) Kyocera Mita FS-C5020N, for example, may not be an absolute speed demon, but it features a superefficient toner system that keeps your cost per page down. A toner-save feature like the Brother HL-2700CN offers is a smart way to extend the life of your consumables. The Lexmark C760n lets you designate which users are allowed to print in color–an easy way to conserve your color toner.Memory is important for users who throw large files at their color printers. A good chunk of built-in memory will keep the printer from getting brain freeze when you toss a graphics-heavy brochure at it. Most printers over $1,000, like the Lexmark C760n, come with 128MB RAM that can be upgraded if necessary. The C760n, for instance, maxes out at 512MB.At the lower end of the cost spectrum is the Brother HL-2700CN. It skims in at $500 with print speeds of up to 8 pages per minute in color and 31 ppm in monochrome. That’s pretty affordable for a network-ready color laser printer. For about $400, the Samsung CLP-510N gives you slightly slower speeds of up to 6 ppm in color and 25 ppm in monochrome; its built-in automatic duplexing is a nice extra.Printer speed involves more than just pages per minute–there’s also the time it takes to get the first page out. That’s where the $899 Xerox Phaser 8500/N flexes its solid-ink muscle. It can get the first color page out in less than 6 seconds, compared to 19 seconds for the Brother HL-2700CN. Solid ink technology also tends to produce very vivid colors and fast speeds overall.When your needs go beyond printing, a multifunction could be right up your alley. The $800 Epson AcuLaser CX11NF covers faxing, scanning and copying as well as printing. One trade-off for all that functionality is speed. Color speeds top out at 5 ppm. Compare to the $999 Hewlett-Packard LaserJet 2840, which comes in at 4 ppm in color and also comes stocked with direct digital photo printing. The Canon ImageClass MF8170c multifunction features high-quality flatbed scanning for $899.Lasers still can’t quite beat specialty inkjets when it comes to photo printing, but their speed and the cost of consumables make them a good choice for companies that focus on brochures and business documents. Throw in networking capability, and you get a versatile solution that will handle the needs of your small office or workgroup–and make your business more colorful.
