Abstract-This paper addresses the use of distributed coherent communication techniques across a wireless network of tactical radios to enable extended-range communications. Conventional tactical communication systems providing multikilometer terrestrial ranges utilize large and costly manpack or vehicular-mount radios. In this paper we discuss techniques for distributing the transmit functions coherently across a network of small, low-power squad radios to achieve similar ranges. We present a testbed implementation of these techniques and overthe-air demonstrations of coherent distributed transmit communications at 3.5 km standoff and 1.25Mbps data rates using radios operating with under 20dBm of transmit power each. *

Inpatient psychiatric facilities can face significant challenges in containing infectious outbreaks during the COVID-19 pandemic. The main objective of this study was to characterize the epidemiology, testing data, and containment protocols of COVID-19 in a large academic medical center during the height of the COVID-19 outbreak. A retrospective cohort analysis was conducted on hospitalized individuals on five inpatient psychiatric units from March 1 st to July 8 th , 2020. Demographic data collected include age, race, gender, ethnicity, diagnosis, and admission status (one or multiple admissions). In addition, a Gantt chart was used to assess outbreak data and timelines for one unit. Testing data was collected for patients admitted to inpatient psychiatric units, emergency room visits, and employees. 964 individuals were hospitalized psychiatrically. The study population included ethnically diverse patients with various mental illnesses. We also describe infection prevention strategies, screening, and triage protocols utilized to safely continue patient flow during and beyond the study period with a low patient and employee infection rate. In summary, our study suggests that early implementation of triage, screening, extensive testing, and unit-specific interventions can help prevent and contain the spread of COVID-19 in inpatient psychiatric units and help facilitate safe delivery of care during a pandemic.

Sociology of religion is the study of the relationship between religion and culture. Sociologists focus on the nature and structure of religious organizations and movements, leadership, the effect of religious commitment on individuals and social process or social change. Central to the discipline is the search for an adequate definition of religion and for a coherent explanation of the distinction between religious myth and social reality.

Background Health system science (HSS) encompasses both core and cross-cutting domains that emphasize the complex interplay of care delivery, finances, teamwork, and clinical practice that impact care quality and safety in health care. Although HSS skills are required during residency training for physicians, current HSS didactics have less emphasis on hands-on practice and experiential learning. Medical simulation can allow for experiential participation and reflection in a controlled environment. Our goal was to develop and pilot three simulation scenarios as part of an educational module for resident physicians that incorporated core and cross-cutting HSS domains.  Methods Each scenario included a brief didactic, an interactive simulation in small-group breakout rooms, and a structured debriefing. The case scenario topics consisted of educational leadership, quality and safety, and implementation science. Learners from four residency programs (psychiatry, emergency medicine, orthopedics, ophthalmology) participated January – March 2021. Results A total of 95 resident physicians received our curricular module, and nearly all (95%) participants who completed a post-session survey reported perceived learning gains. Emotional reactions to the session were positive especially regarding the interactive role-play format. Recommendations for improvement included participation from non-physician professions and tailoring of scenarios for specific disciplines/role. Knowledge transfer included use of multiple stakeholder perspectives and effective negotiation by considering power/social structures. Conclusions The simulation-based scenarios can be feasibly applied for learner groups across different residency training programs. Simulations were conducted in a virtual learning environment, but future work can include in-person and actor-based simulations to further enhance emotional reactions and the reality of the case scenarios.
