Measuring close proximity interactions in summer camps during the COVID-19 pandemic.

Policy makers have implemented multiple non-pharmaceutical strategies to mitigate the COVID-19 worldwide crisis. Interventions had the aim of reducing close proximity interactions, which drive the spread of the disease. A deeper knowledge of human physical interactions has revealed necessary, especially in all settings involving children, whose education and gathering activities should be preserved.

On-Demand LoRa: Asynchronous TDMA for Energy Efficient and Low Latency Communication in IoT.

Energy efficiency is crucial in the design of battery-powered end devices, such as smart sensors for the Internet of Things applications. Wireless communication between these distributed smart devices consumes significant energy, and even more when data need to reach several kilometers in distance. Low-power and long-range communication technologies such as LoRaWAN are becoming popular in IoT applications.

Practice systems for chronic care: frequency and dependence on an electronic medical record.

Objectives: To document the presence and functioning of different practice systems in a small sample of medical groups in Minnesota and to examine the relationship between the presence of practice systems and prior adoption of an electronic medical record (EMR).

Study Design: Descriptive study of the frequency of practice systems in 11 medical groups.

Methods: We recruited 11 medical groups for the study.
