Research team aims to enhance security of medical devices
Tamer Nadeem, Ph.D., the principal investigator of the VCU-based MedKnights project, explained that the project’s focus is on the Internet of Medical Things (IoMT). Nadeem and co-PI Irfan Ahmed, Ph.D., both associate professors in the VCU College of Engineering Department of Computer Science, recently received $600,000 from the NSF’s Office of Advanced Cyberinfrastructure to put together a framework to improve IoMT security. IoMT devices are used in a range of diagnostic, monitoring and therapeutic applications. IoMT includes patient monitors, ventilators, MRI machines — even “smart beds.” Ahmed cited the internet-connected insulin pump is a good example of an IoMT device. Internet connectivity allows for both monitoring and adjusting the dosage remotely — functions that require a high degree of security for patient privacy as well as safety. All IoMT devices are potentially vulnerable to ransomware, denial of service and other malicious hacker attacks. Nadeem points out that IoMT devices have a higher security requirement than traditional IoT devices such as smart doorbells and smart thermostats in homes. “The most important thing in the medical domain is privacy,” Nadeem said. “For IoT devices in your home, you wouldn’t care that much about privacy, but for medical devices, it is an essential thing. You wouldn’t want anyone to know what your health conditions are, or what problems you might have had.” The work of the MedKnights group is important, as the IoMT domain is expanding; there is growth in terms of types of devices, number of patients using them and number of IoMT vendors. Nadeem added that the COVID pandemic and accompanying quarantine and stay-home orders increased the focus of medical-technology providers on the possibilities of IoMT. “Talking to some of the medical-device providers, I’ve learned that they are considering a line of products where they can remotely monitor patients on those devices, and they also can configure those devices remotely,” Nadeem said. Security is a large concern for the new generation of devices, because the current IoMT devices have been hit hard by hackers, he said. Security is an issue that extends from the individual patient to the institution. “Statistics show there are a lot of ransom attacks being done on the health sectors during the pandemic,” Nadeem said. “That motivated us.” The MedKnights team’s preparation for taking on the dragon of malicious IoMT attacks includes building a “test bed,” an isolated hardware/software assembly that Nadeem says will mimic the internet-enabled hospital setting. “In the hospital environment, there’s set of rooms. Each room has a lot of medical devices; they could be wired, or they could be wireless devices,” he said. “But there is no way that we can do what we want to do in a hospital.” The test bed will incorporate IoMT datasets based on typical device behavior, traffic and known malicious attacks. Nadeem explained that MedKnights will explore vulnerabilities of various IoMT hardware and software by subjecting the elements of the IoMT test bed to a range of attacks. “We will try to see in real time how efficient our technologies to monitor or detect these attacks, then try to intervene if we notice any change in the activities on the network,” he said. “Now, if the attacks manage to get into the device, we would like to also to start to see whether we can monitor these devices and observe abnormality or any misbehavior.” Nadeem said the next step is to isolate the source of fishy activity in the test bed network and begin to reverse-engineer the malware. He explained the group will work on understanding the question by looking for the “hole” that created the vulnerability. Ahmed said the MedKnights will bring undergraduates into the project through DURI, the Dean’s Undergraduate Research Initiative at the VCU College of Engineering. High school students will have an opportunity to join the team through a similar program known as the Dean’s Early Research Initiative, or DERI. DURI and DERI are just two ways of getting younger scientists and engineers involved in actual research. “For the last couple of years, I’ve been contacted by local high schools to host a couple of their students during the summer,” Nadeem added. “The students were really excited about it. We came up with some nice ideas about how to extend that work to their classrooms. As we continue this project, we will reach out to the schools, because we would love having a couple of their students involved.”

Expert Says Financial Technologies Can Help Address Climate Change
“Financial technologies offer great promise to tackle climate change and provide pathways for developing sustainable economies and lifestyles,” says Aparna Gupta, a professor of quantitative finance at Rensselaer Polytechnic Institute and co-director of the Center for Research toward Advancing Financial Technologies (CRAFT), the first-ever fintech research center backed by the National Science Foundation. CRAFT brings together industry partners and policy makers to conduct research that is relevant for industry and has potential for commercialization. Dr. Gupta says that blockchain technologies combined with smart contracts and Internet of Things (IoT) devices are set to transform property and casualty insurance that is subject to increasing threats from climate change. Similarly, distributed ledger technologies can be utilized for issuing innovative climate finance securities, such as green bonds and climate derivatives, by facilitating traceable, transparent, and standardized transactions. Regulatory readiness to support blockchain-enabled green bonds and other climate finance securities issuance is underway across the globe. Climate fintech is also set to play a pivotal role in increasing renewable power generation and accelerating the transition to clean energy, according to Dr. Gupta. Digital lending platforms use crowdsourcing models to provide debt financing for residential solar energy systems. Climate-conscious consumers can make spending decisions that minimize their carbon footprint through solutions such as using a credit card that allows them to round up their purchases and use the change for planting trees. In the investment management and advisory space, there is a growing recognition of the need for environmentally sustainable investing. Responding to this need, fintech startups are offering platforms for clean energy investments and enabling investors to construct low-carbon-impact financial portfolios. “Financial technologies innovations are poised to transform almost all aspects of financial services, and in doing so, offer great opportunities to address climate change challenges,” Dr. Gupta says. In addition to her leadership in fintech, Dr. Gupta is at the helm of a team of financial and renewable energy experts developing risk management tools to incorporate renewable energy into the energy market. They will set and standardize risk factors to make it easier for this critical industry to be both productive for investors and creators and systematized for users, similar to the rating system created for the bond market. Dr. Gupta also serves on the Climate Risk Working Group of the Financial Risk Manager Advisory Committee for the Global Association of Risk Professionals tasked with identifying the important climate issues for the training of future global risk professionals. Dr. Gupta is among the many experts and researchers at Rensselaer available to speak on this topic.
Metaverse...have you met AcceleRoute?
The Internet is a testament to the power of evolution. But there's a bigger picture looming. A discontinuity. Driven by a new breed of application environments including the Metaverse, multi-player gaming, VR and more. Will this drive the need for a "new Internet"? Many believe, as a minimum, networking will need a serious upgrade. Moore's Law can cover us for throughput for awhile, but latency is a different story. The speed of light creates the limit. No getting around that. There is only one solution. Park the services closer to the users. And that ushers in a new architectural paradigm in the form of Edge Data Centers. Those facilities will operate in global federations, serving tight geographies while hot-syncing with each other. A tidy solution. Job done, right? Not so fast. If people only cared about what and who is geographically close to them, we might be ok. Remember we need to park the services AND THE DATA close to the users. We're not talking about old slow data like websites, but the fast stuff like fast-twitch gaming, or VR, or avatar movements in the Metaverse. How can a byte in Tokyo stay in "white-hot" sync with a byte in London? Predictive caching, that's how. The new frontier. The geography-buster. Let's say you’re VR-interacting with someone across the planet, there will be a lag. It won't feel real. But what if the application servers use laws of physics to predict far-end movement for local render, with algorithms to reconcile laggy incoming real-position data. Done right, that might feel real. Take that example and scale it in all directions. That's the future. Can incrementally-evolved networks handle that? Its anybody's guess what the future of networking will look like but let's try anyway. Some believe this brave new application world will be the catalyst for significant infrastructure change. Not the " N+1" kind, but the "all-new" kind. The kind we thought we'd never need because incremental upgrades were getting it done. But that was before the Metaverse discontinuity. AcceleRoute is a forward-thinking next-generation network architecture designed for this category of challenge. All-new thinking. Designed from the ground up around a bufferless core architecture, AcceleRoute achieves network throughput and latency on a scale not seen before. Bufferless means no hops. Essentially an endless supply of instantly provisioned virtual direct links, each with as much dynamic bandwidth as needed at any point in time. Incorporating novel paradigms like network fusion and expansion by constellations, AcceleRoute can scale to new orders of magnitude, all while embracing absolute simplicity for network control and management. An infinitely-expandable network, based on new principles, that can glue CPUs/DPUs/GPUs to globalized data with one seamless fabric. Perhaps a full AcceleRoute solution won't be required, but it’s likely the pursuit of network optimizations will be relentless. AcceleRoute represents 2 decades of invention embodied by 36 patents with over 700 claims and more on the way. That's a massive starting position for anyone playing the long game.
As data breaches soar, how will security evolve?
Awareness of data breaches is growing but not nearly at the pace of the problem itself. Indeed, the total number of data compromises jumped 68% in 2021 to an all-time high, impacting more than 293 million people, according to the Identity Theft Resource Center. Also, as more people work from home and embrace Internet of Things devices, individuals can be as vulnerable to hacks and phishing as big corporations and governments, perhaps more so, given that the top three breached data attributes in 2021 were name, social security number and date of birth, the center reported. Bringing a multifaceted perspective to data security challenges is NJIT’s Kurt Rohloff, an academic researcher and entrepreneur who conducts research for the federal government. Rohloff, director of NJIT’s Cybersecurity Research Center, is co-founder and chief technology officer of Duality Technologies, a startup offering data security through homomorphic encryption. His government work includes projects for the Defense Advanced Research Projects Agency of the U.S. Department of Defense and the National Security Agency. Questions that Rohloff can answer include: How has data security evolved? Which tactics fail and why? What’s the economic impact of data breaches? What’s the future of data security?

The Metaverse will change everything!
It will change how we interact. How we consume information. How we have fun. What devices we use. And underlying all of that is networking. And that will change too. "IT infrastructure that powers the Internet will need major upgrades to bring the Metaverse from theory to practice, according to Raja Koduri, SVP and GM of Accelerated Computing Systems and Graphics at Intel. “(The metaverse will) need several orders of magnitude more powerful computing capability, accessible at much lower latencies across a multitude of device form factors. To enable these capabilities at scale, the entire plumbing of the internet will need major upgrades.” Metaverse quality of experience will be intimately tied to networking performance, and latency will be key. Delivering an "instantaneous" Metaverse experience will require a next generation physical network that is designed to deliver highly predictable end-to-end bandwidth with ultra-low latency. "Zero-hop" network designs such as AcceleRoute can achieve this through a bufferless architecture that delivers latency approaching that of direct links while eliminating congestion in the network core.

How to network virtually: What newcomers in Canada need to know
Newcomers to Canada already faced an uphill task of adjusting to their new life and starting a career in Canada, but COVID-related restrictions made things even harder. However, after an initial period of adjustment, virtual networking and remote job interviews have become the norm. Now, even with COVID-19 restrictions easing and people getting vaccinated, some aspects of the “new normal” are expected to continue for the foreseeable future. Due to its relative convenience, virtual networking will likely remain a popular means of building professional connections. This article covers key aspects of how to network virtually and the things you need to know about virtual networking for professional success as a newcomer in Canada. Advantages of virtual networking Start building your Canadian network before you land Before the COVID-19 pandemic, networking was mostly done in-person, which meant that newcomers to Canada could only start building their network after arriving in the country. However, with virtual networking, newcomers have the opportunity to start building their network well in advance of their arrival in Canada. You can start attending virtual networking events or meeting people for online coffee chats while preparing for your move. It can take months to cultivate meaningful professional relationships, so the sooner you start, the better prepared you’ll be to enter the Canadian job market when you land. Opportunity to look beyond your city One major disadvantage of in-person networking is that it geographically limits the people you can meet. With virtual networking, you can connect with experts or professionals, regardless of where they live. If you’re still preparing for your arrival, this gives you a chance to speak to people in different cities and figure out where the best job opportunities are for your industry in Canada. You can also learn about different job markets within Canada and plan your career path based on insights from a more geographically diverse set of people. The convenience of networking from home Attending events and networking meetings is time-consuming. By networking virtually, you can save the time it would take you to travel to the event venue or meeting place. This means that you can accommodate more coffee chats in a day and build your network faster. Many newcomers find it much easier to network from the comfort of their homes, compared to the unfamiliar and chaotic environment of a coffee shop. Since you are the person requesting the meeting, it is expected that you’ll be paying the bill for coffee during in-person meetings. These amounts can quickly add up and might impact your budget, especially if you’re meeting several people each week. In most cases, virtual meetings are also more convenient for the professionals you’re meeting, so your acceptance rate for virtual coffee chats may be higher than for in-person meetings. Easier to follow up and stay in touch Once you’ve made a connection and had an introductory meeting, it is important that you stay in touch with your new contact. However, as your network grows larger, it can become challenging to follow up with everyone on a regular basis—especially if you’re doing these meetings in-person. It’s much easier to stay connected and engage virtually over follow up coffee chats, emails, or social media. This will allow you to follow up more often and build stronger, more meaningful connections. How to build your network virtually as a newcomer in Canada Whether you’re looking to network or find a job, it is important that you keep your LinkedIn profile up-to-date. Your Linked In profile will likely be the first thing people see when they connect with you. Unlike a resume, which is customized for each job, your LinkedIn profile should be generic and should highlight all your skills, experiences, and certifications. Be sure to use a professional headshot and grab people’s attention with a compelling headline. Use LinkedIn’s advanced search filters to find new connections based on their organization, job title, and other criteria. Always personalize your LinkedIn connection request messages. You can also increase your visibility and promote your personal brand by being active on LinkedIn. Post, share, and engage with relevant content to get noticed by other professionals. Interact over social media As a newcomer, LinkedIn is not the only social network you can use to build a network. You can also find professionals you’d like to connect with on Twitter and initiate a conversation. Depending on your industry, Instagram and Facebook groups might be useful platforms for networking—but make sure your profile is professional! Clubhouse is another app where you can virtually meet and share ideas with like-minded people, listen to expert speakers, and ask questions. If your initial interactions go well, ask for a follow up coffee chat to take the conversation forward. Online networking platforms and virtual events Due to the ongoing COVID-19 pandemic, most networking events have moved to a virtual setting. Virtual networking platforms bring together people from similar industries and give you an opportunity to start making connections. Events hosted by industry associations are a great place to meet other professionals in your field. You can also find virtual networking events for different industries and interests on websites like Eventbrite and Meetup. Arrive webinars and workshops are also a great place to learn from and connect with experts. Leave a positive impression on others attending the networking session by behaving professionally and asking intelligent questions. Virtual coffee chats Online coffee chats (also called informational interviews) using tools like Zoom, Google Meet, and Webex, are a great way to build your network virtually. Once you’ve connected with someone on LinkedIn or at a virtual networking event, ask if they’d be open to a one-on-one meeting. Virtual coffee chats give you an opportunity to introduce yourself to established professionals in your industry, showcase your skills, and position yourself as an ideal candidate for future job openings. You can also seek recommendations on other people you should add to your network. If you’re looking for information about a specific organization, role, or industry, informational interviews can be particularly helpful. Be sure to do your research beforehand and have a list of questions ready. Reactivate your existing network As a newcomer, you’ll have to start building your network from scratch in Canada. However, there might be others in your network who are already in Canada. Speak with your friends and family to find out who you might already know here. You can also use LinkedIn to find alumni from your school or colleagues from your previous organizations who’ve since moved to Canada. Leverage your existing network to get introductions to other people in your industry or for job referrals. How do you effectively network virtually? Do your research. Learn what you can about the person you’re meeting beforehand and customize your questions accordingly. Going in prepared will make it more likely for you to get the information you’re looking for, and to make a good impression. Do check your technology. Make sure your internet connection, microphone and camera are in perfect working order before your virtual meeting. Take some time to familiarize yourself with the video call platform prior to your meeting. Always keep your camera on during meetings and if there’s noise in your background, put yourself on mute when the other person is talking. Do be professional. Go in with a list of topics you’d like to discuss and don’t ask personal questions. Be punctual and dress the way you would for in-person networking meetings. Create an appropriate work setting and keep your desk and background distraction-free. If you don’t have a dedicated workspace, apply a professional virtual background in your video call tool. Do be authentic and offer value. Express genuine interest in what people have to say and learn from their experience. Find ways to help the people you’re meeting—it’s a great way to demonstrate your skills in practice! Don’t skip the small talk. In Canada, small talk is a cultural practice, so make sure you allocate some time for it while creating your meeting agenda. It’s also a great way of breaking the ice and getting to know people you’re meeting and relate to them outside of their professional life. Don’t mistake your elevator pitch for a sales pitch. Your elevator pitch is a brief 30 second introduction meant to capture the other person’s interest. Highlight your skills, strengths, and achievements, but don’t oversell yourself. Don’t interrupt or multitask. Appreciate the fact that someone has taken the time to talk to you and pay attention to what they have to say. It’s rude to interrupt or check your phone when someone else is speaking. It can be very distracting, and more importantly, it gives people the impression that you aren’t interested in what they have to say. Be sure to put your phone on silent during networking meetings. There might be other distractions around you at home, such as children or pets, so find a quiet place for meetings. Don’t forget to follow up. If you’re meeting several new people every week, it can be hard to keep the conversation going with all of them. However, regular follow up is the best way to maintain professional relationships. Keep track of all your virtual meetings and create a realistic follow up schedule. Virtual networking has made it easier and more convenient for newcomers to expand their professional networks. As a newcomer to Canada, there are many online platforms and events you can leverage to start building your personal brand and growing your network virtually一even before you come to Canada.

Bowel or fecal incontinence, according to the Mayo Clinic, “is the inability to control bowel movements, causing stool (feces) to leak unexpectedly from the rectum. Also called bowel incontinence, fecal incontinence ranges from an occasional leakage of stool while passing gas to a complete loss of bowel control. Common causes of fecal incontinence include diarrhea, constipation, and muscle or nerve damage. The muscle or nerve damage may be associated with aging or with giving birth.” Dr. Satish Rao is a seasoned gastroenterologist and an expert in digestive health, particularly the brain-gut connection. Rao, a professor of medicine at the Medical College of Georgia at Augusta University, recently offered a Q&A on the topic of fecal incontinence with the journal Gastroenterology & Hepatology. What is the prevalence of fecal incontinence in the adult population? Surveys have indicated a prevalence of approximately 9% to 10% in the United States. A recent study reported a 14% prevalence, although this study was Internet-based and, thus, may not have included many elderly patients, as they may not be as computer-savvy as younger patients. It is safe to say that one in seven Americans currently suffers from fecal incontinence. Prevalence appears to be equal in men and women, although women outnumber men almost three to one when it comes to gastroenterology clinic visits and health care-seeking. Men may be too embarrassed to bring the issue of fecal incontinence to the attention of a physician, but when asked about it, they will admit and discuss it. Also, extracting information from a patient about fecal incontinence depends on how the question is asked. Asking patients whether they have daily leakage vs whether they ever have had leakage or have had leakage in the past month will elicit different responses that a clinician may interpret differently. It is important to remember that leakage is not a physiologic event that a healthy adult should have at any time, even once a month or once a year. Not having the capacity to control bowel evacuation or having leakage unaware of its occurrence signals an abnormality. What are notable risk factors for fecal incontinence? In women, pregnancy can be a risk factor, particularly if giving birth involves pelvic tissue damage, such as injury inflicted by forceps use or the unfortunate occurrence of a significant tear. Neurologic or back injuries are other common risk factors. Also, chronic diarrhea can progress to fecal incontinence owing to severe irritation of the rectum or irritants in stool. Further, any condition that changes the ability of rectal capacity can result in fecal incontinence. These circumstances can include surgery or radiation to the rectal area. Hear from a patient and learn more about Rao's research using magnetic stimulation to treat fecal incontinence. What treatment modalities are currently available? Simple, conservative treatment consists of educating patients about fecal incontinence and instructing them to avoid precipitating events. For example, although many people love to have a meal followed by a cup of coffee and a walk, such a sequence of activities is ill-advised for an incontinent patient: the meal provokes a gastric-colonic response, coffee is a powerful colonic stimulant, and exercise also stimulates motility. This triad creates the perfect storm for a stool leakage or accident while the patient is out on the after-dinner walk. Antidiarrheal therapies can be very effective but only in approximately 15% to 20% of patients. Another treatment is biofeedback, which can correct muscle weakness using behavioral techniques. Biofeedback provides resolution in approximately 50% to 70% of patients. The traditional model of office-based biofeedback requires that the patient make 6 or even up to 10 visits to a specialty clinic. This may mean that some patients must drive very long distances to an appropriate care facility that is staffed with trained personnel or physical therapists. This scenario presents a significant challenge for many patients, which is increasingly being recognized by health care professionals and researchers. Good devices for home-based biofeedback have been scarce; however, such a device was recently approved by the US Food and Drug Administration. The research center at Augusta University has tested it in a clinical trial setting and found it to be quite effective as a home biofeedback treatment. Dextranomer is another treatment modality. It involves injection of small beads of dextran polymers into the anorectal region. The beads form a protective cuff or a buffer to stop stool leakage. Another treatment modality is sacral nerve stimulation using the Medtronic InterStim system. The patient is outfitted with a pacemaker-like device with wires that continuously stimulate the sacral nerves that control stool events. In the case of a torn muscle, suturing the torn ends to reduce the size of the anorectal opening is usually useful for women postpartum, although the effect may not be sustained in the long term. What emerging treatments and research should clinicians be aware of? One emerging treatment developed at Augusta University’s Clinical Research Center is called translumbosacral neuromodulation therapy (TNT). TNT is similar to TAMS and involves the fecal delivery of magnetic energy through an insulated coil to the lumbosacral nerves that regulate anorectal function. The pulses generated are of the same strength as those of magnetic resonance imaging. The team at Augusta University’s research center has shown that TNT mechanistically improves nerve function and substantively improves stool leakage. A sham-controlled study and long-term study are currently underway at Augusta University and Harvard University’s Massachusetts General Hospital. These studies are being sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases. A multicenter study sponsored by the National Institutes of Health that the team at Augusta University also is involved with is the FIT (Fecal Incontinence Treatment) trial. This randomized study compares biofeedback with dextranomer injection. Also, as mentioned, tools are becoming available for home biofeedback that should allow many more affected patients to receive treatment because they can do so in the comfort of their own home. The research center at Augusta University is working on a novel home biofeedback protocol for the treatment of constipation and fecal incontinence. Thus, novel noninvasive tools are emerging for fecal incontinence. The repertoire of current and emerging tools holds the promise of improved outcomes for patients with fecal incontinence. Rao is also the founder of the Augusta University Digestive Health Center.

Kelley expert: Olympics could be targeted by hacktivists, others seeking to embarrass Beijing
Scott Shackelford, associate professor of business law and ethics at Kelley, IU Cybersecurity Risk Management Program chair and director of the Ostrom Workshop Program on Cybersecurity and Internet Governance, said the high-profile diplomatic breach leading up to the games — including the boycott led by the United States – “means that the games could be targeted by hacktivists and other groups seeking to embarrass or otherwise harass Beijing.” Scott Shackelford “There are always issues associated with the Olympics given that they are a target-rich environment for criminals seeking to target athletes and spectators alike,” Shackelford said. “Beijing’s harsh data localization, cybersecurity, and cyber sovereignty laws also raises human rights concerns for athletes and reporters attending the games.” He also noted that ironically while the Olympic games generally often coincide with a peaceful break from ongoing geopolitical tensions, this might not last long. “Witness the Russian invasion of Crimea three days after the 2014 Sochi games concluded,” he said.

Ask an Expert: Are airline concerns over 5G technology warranted?
Airlines around the world announced they were grounding planes this week as the rollout of 5G technology was set to begin. Major providers AT&T and Verizon halted their 5G rollout plans amidst the airlines’ claims that the technology would render a large swath of their aircraft unusable. Dr. Steven Holland, an associate professor at Milwaukee School of Engineering, helps sort out the validity of the airlines’ claims and explain why they are so concerned. Dr. Holland is an expert in electromagnetics, antennas and microwave/radio frequency circuits. “5G wireless systems promise transformational increases in wireless internet speed and connectivity. A key to the higher network speeds is increased 5G radio frequency spectrum usage. While reduced speed 5G has been operational in parts of the US for several years, new 5G frequency spectrum was set to become operational in early December 2021 and offer significantly higher network speeds. “However, rollout was delayed one month when the FAA raised warnings that 5G towers operating in this new spectrum could interfere with airplane radar altimeters, which operate at frequencies just above this new 5G spectrum. Altimeters are critical instruments in modern aircraft that measure a plane’s altitude, and thus potential interference could be disastrous. “While the altimeter and 5G frequency bands do not overlap, they are relatively close together, and the altimeter standards were set decades ago when the radio spectrum was far less crowded. As a result, the altimeter circuitry was not designed to operate in the vicinity of systems like the 5G towers that will transmit radio signals so close to the altimeter frequency range. “Due to limited testing, the FAA and FCC were not able to determine conclusively if the interference concern is warranted before the month-long delay expired in early January, and so an additional two-week delay was instituted. This brings us to today, January 19th – and still no conclusion has been reached by the FCC and FAA. To avoid further rollout delays, today several wireless carriers deployed the new 5G operating band on their networks except for those towers near airports. More extensive testing is needed to determine whether 5G interference is truly a risk to the altimeter systems.” Dr. Holland is available to speak with media about 5G technology and how it can impact aircraft.
