In particular, participants who used VR tended to undershoot their targets by not reaching far enough, while those who used AR tended to overshoot their targets by reaching too far.&nbsp;<br> <br> This effect was noticeable immediately after using VR or AR, but gradually disappeared as participants readjusted to real-world conditions.<br> <br> “Our study explored how using mixed reality (MR) technologies, like virtual reality and augmented reality, affects our ability to perform everyday physical tasks once we return to the real world,” says&nbsp;<strong>Xiaoye Michael Wang</strong>, a research associate in the Faculty of Kinesiology &amp; Physical Education who co-authored the study with Professor&nbsp;<strong>Tim Welsh</strong>.</p> <p>“Specifically, we wanted to understand if the way our brains and bodies adapt to these digital environments changes how accurately we can move and interact with real objects after using VR and AR.”</p> <figure role="group" class="caption caption-drupal-media"> <div> <div class="field field--name-field-media-image field--type-image field--label-hidden field__item"> <img loading="lazy" src="/sites/default/files/styles/scale_image_750_width_/public/2024-08/Michael%20Wang%20and%20student%20embed.jpg?itok=cAldFsCe" width="750" height="500" alt="Researcher adjust a VR headset that is being worn by a student" class="image-style-scale-image-750-width-"> </div> </div> <figcaption><em>Research associate Xiaoye&nbsp;Michael Wang fits a VR display onto study participant Colin Dolynski (photo by Molly Brillinger)</em></figcaption> </figure> <p><br> The researchers say they were surprised by two findings: first, that movement patterns in VR and AR transfer to real-world movements; and second, by how quickly the effects of AR wore off compared to VR, with study participants readjusting to real-world conditions faster after using AR.</p> <p>The difference between VR and AR, they suggest, might be because people in AR can still see and interact with their actual surroundings, which helps them maintain a more accurate sense of depth and distance.<br> <br> “These findings are crucial because they highlight a potential challenge in transferring skills learned in VR or AR to the real world,” says Welsh. “As more industries and training programs adopt these technologies for skill development, it's important to understand how they might affect real-world performance.&nbsp;<br> <br> “For example, this could be relevant for training surgeons, pilots or even everyday skills like driving.&nbsp;Knowing the limitations and effects of VR and AR helps ensure these technologies are used effectively and safely.”<br> <br> The researchers will next be exploring how different types of VR and AR experiences, like those involving more complex or immersive scenarios, affect real-world performance. They’re also interested in seeing how training duration and individual differences such as prior experience with these technologies, influence adaptation and readjustment.&nbsp;<br> <br> “This research will help us better understand how to design VR and AR systems that minimize negative after-effects and maximize their potential for training and skill development,” Wang says.</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Fri, 30 Aug 2024 17:23:24 +0000 Christopher.Sorensen 309169 at Supermassive black hole mergers could be explained by dark matter: Study /news/supermassive-black-hole-mergers-could-be-explained-dark-matter-study <span class="field field--name-title field--type-string field--label-hidden">Supermassive black hole mergers could be explained by dark matter: Study</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2024-08/SupermassiveBinaryBlackHoles_crop.jpg?h=81d682ee&amp;itok=KsORTgPY 370w, /sites/default/files/styles/news_banner_740/public/2024-08/SupermassiveBinaryBlackHoles_crop.jpg?h=81d682ee&amp;itok=FWV7Vizw 740w, /sites/default/files/styles/news_banner_1110/public/2024-08/SupermassiveBinaryBlackHoles_crop.jpg?h=81d682ee&amp;itok=1OBxOsCR 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2024-08/SupermassiveBinaryBlackHoles_crop.jpg?h=81d682ee&amp;itok=KsORTgPY" alt="&quot;&quot;"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>Christopher.Sorensen</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2024-08-06T11:35:00-04:00" title="Tuesday, August 6, 2024 - 11:35" class="datetime">Tue, 08/06/2024 - 11:35</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item"><p><em>A visualization of two supermassive black holes in orbit around each other (image by NASA's Goddard Space Flight Center/Scott Noble;

This is demonstrated by calculations showing that SMBHs continue to draw closer because of previously overlooked interactions with particles within the vast cloud of dark matter surrounding them.</p> <p>“We show that including the previously overlooked effect of dark matter can help supermassive black holes overcome this final parsec of separation and coalesce,” says Alonso-Álvarez, a post-doctoral fellow in the department of physics at 91Թ’s Faculty of Arts &amp; Science and the department of physics and Trottier Space Institute at McGill University, who is first author on the paper. “Our calculations explain how that can occur, in contrast to what was previously thought.”</p> <p>SMBHs are thought to lie in the centres of most galaxies. When two galaxies collide, the SMBHs fall into orbit around each other; as they revolve around each other, the gravitational pull of nearby stars tugs at them and slows them down, causing them to spiral inward toward a merger.</p> <p>Previous merger models showed that when the SMBHs approached to within roughly a parsec, they begin to interact with the dark matter cloud or halo in which they are embedded. These models indicated that the gravity of spiraling SMBHs throws dark matter particles clear of the system.</p> <p>The new model introduced by Alonso-Álvarez and co-authors&nbsp;<strong>James Cline</strong>, a professor at McGill University and the European Organization for Nuclear Research (CERN) in Switzerland, and <strong>Caitlyn Dewar</strong>, a graduate student at McGill, reveals that dark matter particles interact with each other in such a way that they are not dispersed.&nbsp;The density of the dark matter halo remains high enough that interactions between the particles and the SMBHs continue to degrade the SMBH’s orbits – clearing a path to a merger.</p> <p>“The possibility that dark matter particles interact with each other is an assumption that we made, an extra ingredient that not all dark matter models contain,” says Alonso-Álvarez. “Our argument is that only models with that ingredient can solve the final parsec problem.”</p> <p>The background hum generated by these colossal cosmic collisions is made up of gravitational waves of much longer wavelength than those&nbsp;first detected in 2015&nbsp;by astrophysicists operating the Laser Interferometer Gravitational-Wave Observatory (LIGO). Those gravitational waves were generated by the merger of two black holes, both some 30 times the mass of the Sun.</p> <p>The background hum has been detected in recent years by scientists operating the Pulsar Timing Array. The array reveals gravitational waves by measuring minute variations in signals from pulsars, rapidly rotating neutron stars that emit strong radio pulses.</p> <p>In addition to providing insight into SBMH mergers and the gravitational wave background signal, the new result also provides a window into the nature of dark matter. “Our work is a new way to help us understand the particle nature of dark matter,” says Alonso-Álvarez. “We found that the evolution of black hole orbits is very sensitive to the microphysics of dark matter and that means we can use observations of supermassive black hole mergers to better understand these particles.”</p> <p>For example, the researchers found that the interactions between dark matter particles they modeled also explains the shapes of galactic dark matter halos.</p> <p>“We found that the final parsec problem can only be solved if dark matter particles interact at a rate that can alter the distribution of dark matter on galactic scales,” says Alonso-Álvarez.</p> <p>“This was unexpected since the physical scales at which the processes occur are three or more orders of magnitude apart. That’s exciting.”</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Tue, 06 Aug 2024 15:35:00 +0000 Christopher.Sorensen 308819 at 91Թ Engineering student team wins international prize with sustainable wind turbine /news/u-t-engineering-student-team-wins-international-prize-sustainable-wind-turbine <span class="field field--name-title field--type-string field--label-hidden">91Թ Engineering student team wins international prize with sustainable wind turbine</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2024-08/UTWind1-crop.jpg?h=81d682ee&amp;itok=sOQkTF7Y 370w, /sites/default/files/styles/news_banner_740/public/2024-08/UTWind1-crop.jpg?h=81d682ee&amp;itok=JNr3Yjm4 740w, /sites/default/files/styles/news_banner_1110/public/2024-08/UTWind1-crop.jpg?h=81d682ee&amp;itok=ZtvH3fEL 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2024-08/UTWind1-crop.jpg?h=81d682ee&amp;itok=sOQkTF7Y" alt="&quot;&quot;"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>rahul.kalvapalle</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2024-08-06T09:44:46-04:00" title="Tuesday, August 6, 2024 - 09:44" class="datetime">Tue, 08/06/2024 - 09:44</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item"><p><em>From left to right: UTWind team members Robert Zhao,&nbsp;Joeun Yook, Micheal Jing, Dhara Patel, Alexis Terefenko, Justin Ding, Andre Li and Alex Chen (photo by Niels Adema)</em></p> </div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/tyler-irving" hreflang="en">Tyler Irving</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/our-community" hreflang="en">Our Community</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/faculty-applied-science-engineering" hreflang="en">Faculty of Applied Science &amp;

The nose cone was made from recycled polyethylene terephthalate, or PET plastic, which is more sustainable than using new material,” Ding says.</p> <p>“We gathered plastic pop bottles from around campus, including the student-run Hard Hat Café,” says third-year mechanical engineering student <strong>Elena Sloan</strong>, the other co-lead of the mechanical and manufacturing team. “We then cut these bottles into strips and extruded them through a heated nozzle to make 1.75 mm diameter filament, which we could use in our 3D printer.”&nbsp;</p> <p>Once the turbine was complete, it was disassembled and packed into four bags of checked luggage for the flight to the Netherlands. The team’s first stop was Delft, where their turbine underwent testing in a wind tunnel at Delft University of Technology’s Open Jet Facility.&nbsp;</p> <p>The testing showed that the team was able to harvest about 36 per cent of the available energy at a wind speed of 8.5 metres per second, a solid, but not outstanding result.&nbsp;</p> <p>From there, the team members took a three-hour train ride across the country to Groningen, where they gave their technical presentation, followed by the awards ceremony.&nbsp;</p> <p>“We didn’t really expect to win best overall, but we thought we had a decent chance at winning for the most sustainable design,” says&nbsp;<strong>Dhara Patel</strong>, incoming co-president of UTWind and a second-year electrical engineering student.&nbsp;</p> <p>“When we found out we didn’t win that award, we were pretty devastated, but it was a complete shock to then find out that we won the whole competition – our mouths just hung open for a while.”&nbsp;</p> <blockquote class="instagram-media" data-instgrm-captioned data-instgrm-permalink="https://www.instagram.com/p/C9Iwnd-sWIk/?utm_source=ig_embed&amp;utm_campaign=loading" data-instgrm-version="14" style=" background:#FFF;

We’d like to take on that challenge, and ultimately put one on our own campus buildings to generate clean wind power.”&nbsp;</p> <p>Patel was a high school student when UTWind won their first competition in 2022, and says reading about their success was one of the things that inspired her to study engineering at 91Թ. The team she eventually came to co-lead now includes more than 50 engineering students as well as some from the Faculty of Arts &amp; Science.</p> <p>Students are divided into five sub-teams: aerodynamics, mechanical and manufacturing, control systems, power systems and sustainability.&nbsp;</p> <p>The team members say they’re energized by their win, and have big plans for next year.</p> <p>“We’ve learned so many lessons – before, during and after the contest,” says <strong>Robert Zhao</strong>, UTWind's other incoming co-president and an undergraduate student in the department of physics.</p> <p>“But our competitors have also learned those lessons, and there are more of them than ever before. We need to improve our winning design, making it more robust and more mature to better defend our title.”&nbsp;</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Tue, 06 Aug 2024 13:44:46 +0000 rahul.kalvapalle 308924 at Pharma companies sponsored over a million events for U.S. health professionals in a single year: Study /news/pharma-companies-sponsored-over-million-events-us-health-professionals-single-year-study <span class="field field--name-title field--type-string field--label-hidden">Pharma companies sponsored over a million events for U.S. health professionals in a single year: Study</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2024-07/GettyImages-172960226-crop.jpg?h=81d682ee&amp;itok=Ru_QljpE 370w, /sites/default/files/styles/news_banner_740/public/2024-07/GettyImages-172960226-crop.jpg?h=81d682ee&amp;itok=hk3CLZmG 740w, /sites/default/files/styles/news_banner_1110/public/2024-07/GettyImages-172960226-crop.jpg?h=81d682ee&amp;itok=4HG6pEUA 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2024-07/GettyImages-172960226-crop.jpg?h=81d682ee&amp;itok=Ru_QljpE" alt="doctor handing over a signed prescription"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>rahul.kalvapalle</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2024-07-18T13:01:47-04:00" title="Thursday, July 18, 2024 - 13:01" class="datetime">Thu, 07/18/2024 - 13:01</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item"><p><em>(photo by&nbsp;fluxfoto/Getty Images)</em></p> </div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/rebecca-biason" hreflang="en">Rebecca Biason</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/breaking-research" hreflang="en">Breaking Research</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/research-and-innovation" hreflang="en">Research and Innovation</a></div> </div> <div class="field field--name-field-subheadline field--type-string-long field--label-above"> <div class="field__label">Subheadline</div> <div class="field__item">A new study from 91Թ’s Lawrence Bloomberg Faculty of Nursing examines the scale of industry-sponsored events targeting health professionals</div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>Research led by the 91Թ’s Lawrence Bloomberg Faculty of Nursing is shedding light on the scale of pharmaceutical industry-sponsored events that target health professionals responsible for prescribing medications.</p> <p>Promotional events attended by prescribers such as physicians and nurse practitioners are a key component of marketing campaigns for new drugs and devices. But there is little transparency around their scope and extent.</p> <p>In a bid to increase transparency on industry-prescriber interactions, researchers led by Assistant Professor <a href="https://discover.research.utoronto.ca/4441-quinn-grundy"><strong>Quinn Grundy</strong></a> examined data from the <a href="https://openpaymentsdata.cms.gov/">Centers for Medicare and Medicaid Services (CMS) Open Payments</a>, a public database of payments made by drug and medical device companies to medical professionals.</p> <p>Their study, <a href="https://jamanetwork.com/journals/jama-health-forum/fullarticle/2820408">published in <em>JAMA Health Forum</em></a>, found that there were over 1.1 million industry-sponsored events in the U.S., one of the world’s biggest pharmaceutical markets, in 2022 alone. The top 10 products&nbsp;– based on number of sponsored dinner events&nbsp;– were the focus of over 16,000 dinners sponsored by seven companies.</p> <p>“Identifying over one million of these events in one year alone – and their tendency to be for specific products – should give us pause and indicate that we need to understand the prevalence of these events from a systems perspective, considering their impact on prescribing practices,” says Grundy, who is also the director of the World Health Organization (WHO) Collaborating Centre in Governance, Accountability, and Transparency in the Pharmaceutical Sector.</p> <p>Grundy notes that there is already&nbsp;a large body of evidence&nbsp;on the relationship between payments and physician prescribing outcomes. Receipt of industry payments, including low-value payments for food and beverage, is often associated with physicians prescribing higher quantities of promoted and higher-cost drugs, such as brand name drugs over generics.</p> <p>The Open Payments database was established under the Affordable Care Act in 2012 in the hopes of creating greater transparency around the relationships between clinicians and the pharmaceutical and medical device industries.</p> <p>Using the database, researchers were able to examine records of payments from pharmaceutical and device companies to clinicians for food and beverage and to link these across matching variables to identify – and quantify – in-person sponsored events for specific products. Excluding conferences and virtual events, the numbers indicated that these industry-sponsored events were quite widespread, across various states.&nbsp;&nbsp;</p> <p>What this shows, Grundy says, is that while individual health professionals may only attend a few of these events, pharmaceutical companies are sponsoring hundreds of them nationwide.</p> <p>“When you think of the number of events and the number of health professionals attending these events, what emerges is a picture of a campaign that is able, at a national scale, to amplify perspectives about a promoted drug that are likely favourable to the sponsor,” says Grundy.</p> <p>The study did not reveal a particular pattern in terms of the types of products that were more likely to be promoted using industry sponsored events. However, there was evidence that two of the top 10 products, both mental health-oriented drugs, had more events for nurse practitioners than physicians, indicating their importance as prescribers in the pharmaceutical market.</p> <p>In 2021, the first data on industry payments to prescribing nurses was released in the U.S. Grundy says this was an important and positive step towards transparency (Canada lags behind in this regard: there is currently no data or mechanism that requires pharmaceutical or device companies to report payments to physicians or nurse practitioners).</p> <p>This study, funded by the Greenwall Foundation’s <a href="https://greenwall.org/making-a-difference-grants">Making a Difference Grants</a> program, is part of a multi-phase project that aims to analyze the new data on industry payments to advanced practice nurses in the U.S.</p> <p>Grundy says she hopes the research “sparks some conversations in professional circles about how to interact with industry in ways that are in the best interests of population health” – and leads to more research on best practices in prescribing.</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> <div class="field field--name-field-add-new-story-tags field--type-entity-reference field--label-above"> <div class="field__label">Add new story tags</div> <div class="field__items"> <div class="field__item"><a href="/news/tags/lawrence-bloomberg-faculty-nursing" hreflang="en">Lawrence Bloomberg Faculty of Nursing</a></div> </div> </div> Thu, 18 Jul 2024 17:01:47 +0000 rahul.kalvapalle 308469 at 91Թ welcomes federal budget's investments in research and innovation /news/u-t-welcomes-federal-budget-s-investments-research-and-innovation <span class="field field--name-title field--type-string field--label-hidden">91Թ welcomes federal budget's investments in research and innovation</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2024-04/UofT92722_EV-Chem-Lab-3-crop.jpg?h=f1476387&amp;itok=HBdmIp-2 370w, /sites/default/files/styles/news_banner_740/public/2024-04/UofT92722_EV-Chem-Lab-3-crop.jpg?h=f1476387&amp;itok=kHbG7xWq 740w, /sites/default/files/styles/news_banner_1110/public/2024-04/UofT92722_EV-Chem-Lab-3-crop.jpg?h=f1476387&amp;itok=1C-52aR1 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2024-04/UofT92722_EV-Chem-Lab-3-crop.jpg?h=f1476387&amp;itok=HBdmIp-2" alt="woman working in an EV lab at 91Թ Scarborough campus"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>Christopher.Sorensen</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2024-04-16T14:39:56-04:00" title="Tuesday, April 16, 2024 -

"Now, for the first time, we’ll be able to measure that, whereas people have been extrapolating it before."</p> <figure role="group" class="caption caption-drupal-media align-center"> <div> <div class="field field--name-field-media-image field--type-image field--label-hidden field__item"> <img loading="lazy" src="/sites/default/files/styles/scale_image_750_width_/public/2023-12/5_Drout_Magellan-crop.jpg?itok=jVp5lV8H" width="750" height="563" alt="&quot;&quot;" class="image-style-scale-image-750-width-"> </div> </div> <figcaption><em>Assistant Professor Maria Drout with the Magellan Telescope at Las Campanas Observatory (photo by Tom Holoien/Maria Drout)</em></figcaption> </figure> <p>Drout and her colleagues propose that these newly discovered stars will eventually explode as hydrogen-poor supernovae.

These objects are at the stage immediately before they become double-neutron-star or neutron-star-plus-blackhole systems that could eventually merge.</p> <p>“Many stars are part of a cosmic dance with a partner, orbiting each other in a binary system. They’re not solitary giants but part of dynamic duos, interacting and influencing each other throughout their lifetimes,” says&nbsp;<strong>Bethany Ludwig</strong>, a PhD student in the David A. Dunlap department of Astronomy &amp; Astrophysics&nbsp;and third author on the paper. “Our work sheds light on these fascinating relationships, revealing a universe that is far more interconnected and active than we previously imagined.</p> <p>“Just as humans are social beings, stars too, especially the massive ones, are rarely alone.”</p> <figure role="group" class="caption caption-drupal-media align-center"> <div> <div class="field field--name-field-media-image field--type-image field--label-hidden field__item"> <img loading="lazy" src="/sites/default/files/styles/scale_image_750_width_/public/2023-12/4_ObservingLasCampanas.jpg?itok=3tzQLP6z" width="750" height="563" alt="&quot;&quot;" class="image-style-scale-image-750-width-"> </div> </div> <figcaption><em>(Left to right):&nbsp; Bethany Ludwig, Anna O’Grady, Maria Drout and Ylva Götberg (all authors on the paper) at the Magellan Telescopes at Las Campanas Observatory in Chile (photo by Ylva Götberg)</em></figcaption> </figure> <p>As stars evolve and expand to become red giants, the hydrogen at the outer edges of one can be stripped by the gravitational pull of its companion star – leaving a very hot helium core exposed.

That technology is now on its way to commercialization, thanks in part to $5 million in new federal funding from&nbsp;<a href="https://www.sdtc.ca/en/" rel="noopener" target="_blank">Sustainable Development Technology Canada</a>.</p> <p>“Windows are the weakest energy link in any building,” says Kherani,&nbsp;a professor in the department of material science and engineering in the Faculty of Applied Science and Engineering&nbsp;who is&nbsp;jointly appointed&nbsp;to the Edward&nbsp;S. Rogers Sr. department of electrical and computer engineering.</p> <p>“Think of heat escaping in the winter months and heat entering the cool, ventilated space during the summer months," says Kherani, who&nbsp;co-founded 3E Nano in 2015.&nbsp;</p> <p>Kherani explains that a&nbsp;window’s resistance to heat flow is measured by the R-value, which increases based on its ability to prevent heat from flowing into or escaping from a building. Currently, 3E Nano windows –&nbsp;in prototype as well as in pre-alpha deployment –&nbsp;rate R8 and higher.</p> <p>"This compares remarkably to an average window&nbsp;whose R-value lies in a range from R1 of a single pane, to R3, a dual pane.”</p> <p>How was 3E Nano able to achieve this breakthrough? In its simplest configuration, the 3E Nano coating comprises a nano-thin metallic film sandwiched between two sapphire-like nano-thin films. This three-layered&nbsp;stack is opaque to certain wavelengths of light, but not others. As a result, the coating can control the flow of light entering and leaving the building over three parts of the solar spectrum: the visible, the near-frequency infrared and the mid-frequency infrared.</p> <p>Both near-infrared light&nbsp;–&nbsp;which accounts for almost half of the sun’s total energy&nbsp;–&nbsp;and mid-infrared light can be reflected away. This keeps the sun’s heat from penetrating indoors, but it also keeps room heat inside the building from escaping through the windows,&nbsp;achieving low emissivity. At the same time, natural visible light is allowed through the window to the interior, reducing the need for artificial interior lighting.</p> <p>Kherani believes 3E Nano’s coating&nbsp;is poised to become a mainstream product.&nbsp;He credits the industry experience of 3E Nano’s team with&nbsp;a critical pivot in the research.</p> <p>“Combining earth-abundant aluminum and nitrogen results in a coating material similar to sapphire in its optical and structural properties,” he says. “The stability and multi-functional character of the sapphire-like structure is suited to low-cost, high-volume manufacturing.”</p> <p>The coating is applied by sputter deposition&nbsp;–&nbsp;a process which hurls argon atoms into an aluminum target in a vacuum system, knocking the aluminum atoms like billiard balls into a lightweight polymer substrate.</p> <p>After adding nitrogen gas, the resulting chemical reaction forms a colourless film only tens of nanometres thick (approximately one-thousandth of the thickness of a hair strand). This&nbsp; combined with a nano-thin silver layer results in a robust coating that can be tuned for optical and electrical properties.</p> <p>Kherani and his team envision other aspects of the perfect window as integrated functionalities ranging from metamaterial structuring to dynamic systems that maintain ideal temperatures and daylighting (the practice of placing windows so that sunlight can provide effective internal lighting) within buildings.</p> <p>“In the lab, we’ve created a metamaterial that retains low emissive and solar-control properties but has high transparency in the gigahertz range critical for communication –&nbsp;nature-inspired with near-invisible hexagonal honeycomb patterns,” Kherani says.</p> <p>“Professor Kherani has his eye on sustainability solutions that remain scalable,” says&nbsp;Professor&nbsp;<strong>Deepa Kundur</strong>, chair of the department of electrical and computer engineering. “His startup 3E Nano is a shining example of how industry can shape and direct research, and he’s given 3E Nano every chance at a positive impact in the green marketplace.”</p> <p>Kundur also points out that it's because of researchers like Kherani that&nbsp;<a href="/news/u-t-among-top-10-research-organizations-cited-global-innovators" rel="noopener" target="_blank">91Թ was recently named a top-10 research institution for global innovation</a>.</p> <p>Kherani is encouraged by 3ENano's&nbsp;progress and optimistic about the company’s ability to help transform the building sector, which ranks a close second to transportation in energy-related carbon dioxide emissions.</p> <p>“Although the shortest distance from point A to point B is a straight line, finding that straight line is not a simple matter," he notes.&nbsp;"On the other hand, we are in a promising place today, and we can clearly see where we need to be.”</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Thu, 16 Mar 2023 21:15:00 +0000 siddiq22 180809 at Can restricting blood flow to athletes' limbs while training boost performance?

The cuffs remain inflated for a brief period of about five minutes before being released for about five minutes, allowing for normal blood flow to resume through the limb. The process is repeated three to four times.&nbsp;</p> <p>Researchers have speculated that if IPC improves the muscle’s ability to tolerate lack of oxygen supply, then perhaps this feature could be beneficial for prolonging exercise performance.&nbsp;</p> <p>“Several studies have shown IPC to improve exercise performance, but there is little evidence as to&nbsp;why,” says O’Brien, who explored the question&nbsp;in his master’s thesis. “I wanted to fill in some of the gaps.”&nbsp;</p> <p>While most of the studies had measured the effects of IPC on lower body exercises such as running or cycling, O’Brien was interested in investigating the effects of IPC on arm cycling exercise. He was also curious to see whether it might be useful for supramaximal intensity exercise – where the participants exercise as hard as they possibly can for the entirety of the test as opposed to pacing themselves.&nbsp;</p> <p>“I theorized that if IPC works for upper body exercise, it may be useful for unique populations such as para-athletes or paddlers to help enhance their performance,” he says. “I was also interested in whether IPC was useful for supramaximal intensity exercise as most of the studies had investigated IPC during endurance exercises.”&nbsp;</p> <p>O'Brien also wanted to investigate whether IPC works due to the placebo effect, a phenomenon whereby a treatment works due to the psychological expectations that it will work, as some researchers have speculated.</p> <p>Working under the supervision of Professor&nbsp;<strong>Ira Jacobs</strong>, O’Brien recruited 18 athletic participants who completed three 45-second-long sprints using an arm cycle ergometer on separate visits to the lab. The first sprint served as a control trial, where the participants did not receive the IPC treatment, and instead lay passively for 30 minutes before exercise. During the other two visits, the participants completed their sprint after receiving either IPC (five minutes applied to both arms four times) or the placebo treatment. The placebo treatment consisted of the same protocol as the IPC trial, only at a low cuff pressure that did not interfere with their blood flow. The participants were told that the placebo treatment was also expected to enhance their performance through a similar mechanism to the high pressure treatment despite there being no actual benefit.&nbsp;</p> <p>“We found that the average power outputs generated by the participants in our study were significantly higher after both the IPC and placebo treatments compared to the control trial,” says O’Brien. “However, the power outputs were not different between IPC and the placebo condition.”</p> <p>While this result can be seen as an indication that IPC is in fact a placebo effect, O’Brien believes it is more likely that the changes in performance were due to the order that the participants completed the trials.&nbsp;</p> <p>“Because the arm ergometer exercise was foreign to our participants, and the participants completed the control trial first, we believe that the second and third sprints were improved due to a learning effect rather than a performance enhancing effect of the IPC or placebo conditions,” he says. “This was supported through our statistical analyses as well as our lack of evidence of changes in the physiological variables such as oxygen consumption, heart rate, muscle blood flow or blood chemistry.”</p> <p>While the study did not find clear evidence of a performance enhancing effect of IPC, these findings help to add information on the growing research area of ischemic preconditioning and exercise performance, says O’Brien.</p> <p>“Research in this area has been active for over a decade, however much is still unknown about how IPC works in relation to exercise,” he says. “Our study is a small but important contribution toward building an improved understanding of the nuances of how IPC influences exercise performance.</p> <p>“In the end, we hope to help illuminate the effects that this treatment has on exercise to help support athletes of all capabilities to achieve their full potential.”&nbsp;</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Thu, 15 Dec 2022 17:58:12 +0000 Christopher.Sorensen 178427 at A night of big ideas: Celebrating 50 years of the Connaught Fund at 91Թ /news/night-big-ideas-celebrating-50-years-connaught-fund-u-t <span class="field field--name-title field--type-string field--label-hidden">A night of big ideas: Celebrating 50 years of the Connaught Fund at 91Թ</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2022-11-30-Big-Ideas-at-U-of-T---Connaught_Polina-Teif-22-Edit.jpg?h=afdc3185&amp;itok=aALu6s5p 370w, /sites/default/files/styles/news_banner_740/public/2022-11-30-Big-Ideas-at-U-of-T---Connaught_Polina-Teif-22-Edit.jpg?h=afdc3185&amp;itok=oCS_6RTR 740w, /sites/default/files/styles/news_banner_1110/public/2022-11-30-Big-Ideas-at-U-of-T---Connaught_Polina-Teif-22-Edit.jpg?h=afdc3185&amp;itok=_xaVd1sq 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2022-11-30-Big-Ideas-at-U-of-T---Connaught_Polina-Teif-22-Edit.jpg?h=afdc3185&amp;itok=aALu6s5p" alt="view of the stage during the roundtable"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>mattimar</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2022-12-12T14:15:26-05:00" title="Monday, December 12, 2022 -
