Taking SD-WAN QoS to the Next Level
Backhauling traffic to a corporate data center has been a defacto approach for ensuring full security treatment across all users and applications. But QoS took a hit when services started moving to the cloud. Michael Cooney, Senior Editor at Network World describes how SD-WANs have provided a solution for that in his article entitled "Fannie Mae’s journey to SD-WAN means less reliance on MPLS and VPNs." In that article, Ken Reddick, Director of Network Engineering at Fannie Mae says “What we are moving to is a cloud-edge environment where user traffic is now sent directly where it needs to go without hitting the data center, and what that has brought us is a four-fold increase in network performance and cut latency by 50%.” SD-WANs are providing a valuable new approach for delivering optimal connectivity between end-users and cloud services, however QoS is still ultimately determined by the underlying physical networks. To take QoS to the next level will require a next generation physical network that is designed to deliver highly predictable end-to-end bandwidth and ultra-low latency. Network designs such as AcceleRoute achieve this through a bufferless architecture that eliminates congestion in the network core. Low latency bandwidth can be dynamically scaled up or down in real-time based on traffic load. Networks such as AcceleRoute provide an ideal underlay network option for SD-WANs by delivering consistently superior service levels regardless of traffic and geography For more information about AcceleRoute, contact: Lesley Gent Director Client Relations, InventionShare™ lgent@InventionShare.com (613) 225-7236, Ext 131 Or visit our website at www.InventionShare.com
Georgia Southern University saw a significant increase in grant and contract funding awarded to its faculty for research in the 2020 fiscal year. Georgia Southern faculty and staff received 144 awards totaling $10.7 million, which represents nearly a 67% increase over the previous year. The University received $6.4 million in FY2019 and $5.6 million in FY2018. This year marks the first time that faculty-led research at Georgia Southern broke the $10 million threshold. Vice Provost for Research Christopher Curtis, Ph.D., praised the faculty for their achievements. “These are highly competitive awards from the state, the federal government and private enterprises,” he said. “To grow our research portfolio in a national environment of diminishing funding is truly remarkable and a testament to the intellectual firepower and creativity of our professors. Georgia Southern is a Public Impact Research university, which means that the success of these researchers will be felt well beyond the confines of the University and will extend across the region.” Faculty engage in research that contributes significantly to the University’s $1.4 billion economic impact on the coastal region and that makes Georgia Southern a leading Public Impact Research university in the Southeast. The Allen E. Paulson College of Engineering and Computing, the College of Science and Mathematics and the Jiann-Ping Hsu College of Public Health each received over $2 million in sponsored awards in FY2020.

Environment-Friendly Compound Shows Promise for Solar Cell Use
A widespread transition to solar energy will depend heavily on reliable, safe, and affordable technology like batteries for energy storage and solar cells for energy conversion. Nikhil Koratkar, an endowed professor of mechanical, aerospace, and nuclear engineering at Rensselaer, has dedicated much of his research to exploring ways to make a wide-range of batteries more efficient, affordable, and safe. In research published in Advanced Functional Materials, Koratkar and a team of engineers, material scientists, and physicists demonstrated how a new material — a lead-free chalcogenide perovskite — that hadn’t previously been considered for use in solar cells could provide a safer and more effective option than others that are commonly considered. “The National Academy of Engineering has defined 14 grand challenges; one of those is to make harvesting energy from the sun cheaper and more widespread,” Koratkar said. "That’s the motivation of this work, to come up with new materials that could rival the efficiency of silicon, but bring down the cost of manufacturing solar cells, and that is the key to achieving this goal.” Koratkar is available to talk about this recent discovery, and his broader expertise and research in energy storage.
A record number of female candidates are running in 2020
It’s been a full century since the 19th Amendment was passed in the United States, giving women the right to vote. This year, women are not only casting their ballots - they're appearing on them in record numbers. A record number of women are running for Congress this year, boosted in part by a surge of Republican women seeking office in a party struggling to regain lost ground with female voters. The influx adds to the advances female candidates — mostly Democrats — made in the 2018 midterm election that helped reshape the makeup of Congress. It also has echoes in the presidential race, based on voting patterns from two years ago and Democrat Joe Biden’s lead in polls over President Donald Trump among female voters. Biden has vowed to pick a woman as running mate. As of July 1, 574 women had filed to run in primaries for U.S. House seats, topping the record 476 from two years ago, according to data compiled by the center. Another 58 women filed to run for the Senate, compared with 53 in 2018. In all, that’s a 20% increase in women making congressional bids. July 13 – Providence Journal It is an impressive number and one every American should be proud of. But there are a few questions that still need to be asked. With close to 220 GOP women vying for a seat in Congress – has the party that traditionally does not have the support of women voters finally changed its course? Are female candidates motivated by the need to change when it comes to key issues like health care, the environment, and the economy? If you are a journalist looking to cover the increased number of females running for elected office this November – then let our experts help.

Virtual Reality-Based Surgical Simulations Could Make Patients Safer
Suvranu De, the director of the Center for Modeling, Simulation, and Imaging in Medicine at Rensselaer, has dedicated more than a decade of research to making surgery safer by developing virtual reality-based surgical training simulations that closely mimic the optics and haptics a surgeon may encounter in the operating room. A new $2.3 million grant from the National Institute of Biomedical Imaging and Bioengineering of the National Institutes of Health will further his research in this space, by supporting the development of a collaborative virtual reality-based surgical simulation environment that allows medical professionals to practice technical, cognitive, and interpersonal skills as a team. “People will be wearing head-mounted displays, and they will be immersed in a virtual operating room working on a virtual patient as a team,” De said. “We want to have an expert team in the operating room focused on the treatment of a patient, and not just a team of experts.” Conceptually, this approach is similar to crew resource management practiced by aviation pilots, which has led to a significant reduction in aircraft accidents. The Virtual Operating Room Team Experience (VORTeX) simulation system will provide realistic distractions, interruptions, and other stressors that medical professionals may encounter in an operating room. Traditionally, this type of simulation training has required mannequins, instructors, and a dedicated space, as well as significant coordination and resources. In contrast, the VORTeX system will be both distributed and asynchronous – allowing participants to join the simulation from different locations, and instructors to review the simulation and provide feedback at their convenience. Machine learning algorithms will be used to crunch the data and provide feedback to participants, who will be able to return to the virtual environment to review their performance. De is available to discuss how this type of virtual training is developed and implemented.
A New Kind of "Zoom" Science Lesson
With the end of the school year just around the corner and numerous COVID-19 restrictions still in place for the foreseeable future, many parents are worried. Summer camps in Pennsylvania are beginning to open—but with limited capacity. So, what are working caretakers to do with their kids all day? Villanova University professor of chemistry Marta Guron, PhD, and six of her students have created informative science lessons that bring learning and fun together in a virtual environment. In a typical year, Dr. Guron gathers a group together who volunteer their time by visiting local elementary schools to perform hands-on science experiments with fourth-graders, fifth-graders and sixth-graders. When in-person lessons were no longer an option due to the pandemic, the Villanovans adapted their strategy. Though finals are over and Villanova's campus remains empty, six dedicated undergraduate and graduate students are still finding time to go virtual with their lessons. In the following video, Dr. Guron and the Villanova students use PowerPoint, plastic containers, water and their choice of "solids" to talk about density. The supplies for this outreach program are typically provided by Villanova, but in light of everyone being "stuck at home," Dr. Guron encouraged the grade school students to experiment. "If there is something that you don't have at home, it's OK to try to replace different things. For example, some students, when they added different solids, they might have added a penny or a piece of wood. But others might have a bead or something else. It doesn't... much matter." She adds, "Please make sure you talk to your mom and dad before you take anything out!" Some other experiments the team has done include assessing symmetry in crystals, making the gooey, Double Dare-inspired "gak," building a fruit battery, investigating sound and studying capillary action in flowers. Dr. Guron is grateful that her students were still interested in the project, even after the end of a particularly unusual semester. "I thought it was awesome that these students all volunteered time and effort after their final exams were over because of their dedication to the program and to the kids. We are truly a community of helpers."
Twelve students in the Doctor of Physical Therapy (DPT) program at Georgia Southern University were awarded scholarships totaling more than $17,000 from the Savannah American Business Clubs (AMBUCS). “This is a recognition of the dedication we have to AMBUCS and helping others in our community,” said scholarship recipient and AMBUCS student leader Alexandra Adams. “Most of us are paying for our education with loans, and the scholarship helps relieve some of the financial burden that comes with pursuing a graduate degree. I am very thankful that AMBUCS has considered me for this scholarship the past two years.” The organization has hosted a League of Exceptional Bowlers on Saturdays for more than 50 years. The DPT students join the Savannah AMBUCS league to assist bowlers with physical and intellectual disabilities to promote an inclusive and competitive environment. In addition to the hands-on experiences, DPT students have the opportunity to interact with different members of the community. “It shows our commitment to the inclusion of our community and our passion for encouraging movement for everyone, despite their limitations, to increase their quality of life,” Adams said. “The program reinforces our classroom training, as well as, enhances our communication skills with others. Each member of our DPT program gets as much of a benefit from attending AMBUCS as the bowlers do.” A century-old membership organization dedicated to helping people with disabilities, the Savannah AMBUCS awards scholarships to students pursuing careers in the allied health professions and who volunteer with AMBUCs.

Voice teachers and singers are facing an avalanche of questions while planning how to return to “normal operations” as restrictions ease from the COVID-19 pandemic. Singers generally expel more breath and saliva than normal talkers, so are their social distancing requirements different than most? If public health officials require six feet of separation at all times, how does a choir practice and perform? If voice lessons have to be done remotely, how can tone and pitch be properly evaluated via an internet connection? These are just some of the dilemmas facing voice teachers and music professors. “We are highly concerned in the arts related to how we deal with teaching when we return to campuses, classrooms and studios, particularly with singing,” said Allen Henderson, executive director of National Association of Teachers of Singing (NATS) and professor of voice at Georgia Southern University. “Singers are what we might call super-emitters — in terms of what is expelled in a breath. What kind of precautions do we need to take?” To help start answering such questions, Henderson and NATS organized a webinar called “A Conversation: What Do Science and Data Say About the Near-Term Future of Singing?” It is scheduled for Tuesday, May 5, at 5 p.m. He said within 24 hours of the webinar’s announcement, more than 2,000 people had signed up. “I was able to secure one of the major researchers on aerosolization of viruses,” Henderson said. “I suspect there will be a lot of higher education arts administrators in attendance and the information shared will be used widely in formulating responses to the unique problems of teaching music when reopening occurs.” Henderson noted that when the country shut down, the process was fairly quick and uniform. As organizations such as universities make plans to return to ‘normal’ operations, leaders will likely have to develop their own plans unique to their settings. “It will be complicated, and it’s about what protocols institutions and individuals have in place in regard to testing and contact tracing so that there’s a sense that we are creating as safe an environment as possible,” Henderson said. “Our job is to arm our colleagues with the best possible science-based information we can.” To learn more about the upcoming webinar, simply visit the story attached:
Forecasting demand of any product for industry, manufacturing and even retail is already a difficult task. And now, amid a global pandemic that has seen some industries grind to a halt while others ramp up to keep up - means that measuring expectations about demand is key to corporate survival during these trying times. We have not experienced a global pandemic like the coronavirus in last 100 years. The sheer increase in demand for everyday necessities like toilet paper, sanitary wipes and bottled water is putting undo stress on a lean global supply chain. It is testing the agility of many retailers and consumer packaged goods (CPG) companies as they attempt to ramp up manufacturing facilities and logistical operations while struggling to keep up with consumer demand. Business executives are looking to data, analytics, and technology for answers on how to predict and plan for the surge and, ultimately, the decline in consumer demand. It is significantly easier to shut down facilities than it is to quickly boost production and capacity. The biggest unknown is whether there will be a delayed economic recovery or a prolonged contraction. Regardless of the outcome, retailers and their CPG suppliers will need to think ahead and be prepared to act quickly.

As the global pandemic touches almost all parts of the United States – it is essential that the public receives only accurate and definitive information from credible and expert sources as news, media and information reaches million of people across the country. An invisible enemy is killing thousands and forcing people worldwide to cower behind closed doors. Unfounded conspiracy theories and miracle “cures” abound on social media. Politicians and pundits send mixed messages about how to protect yourself. Who you gonna call? - Bedford Gazette, April 14 As the coronavirus rampages, the public increasingly is turning to experts in academia and government -- the educated, experienced “elites” that many Americans had tuned out. The Coronavirus 2019 (COVID-19) situation is certainly new to all of us. As guidance from the CDC changes and instructional methods transition, there are experts at Georgia Southern who can help to answer questions such as: How should we best address this pandemic as a nation? How should we best address this pandemic individually? What does it mean to “flatten the curve?" What is the economic impact of COVID-19? How do you best manage employees virtually? Why are grocery stores having trouble keeping inventory on their shelves? Should we prepare for a lapse in groceries and goods? What contributes to the fear and panic in disasters and pandemics? What do educators, parents and students need to know to prepare for online learning in the K-12 and college settings?
