Objective: Peritraumatic dissociation (PD) and coping strategies (CS) around the time of trauma are significantpredictors of acute and long-term posttraumatic symptomatology (PTS), but it is unclear howthey relate to each other. The aim of this study was to examine their association using a nationwide, representativesample following the September 11 attacks in the United States (N = 3,134). Method
This paper shows how a channel sounder can be built with National Instruments (NI) Universal Software Radio Peripheral (USRP) equipment, featuring onboard FPGA processing and utilizing open-source tools. Compared to other USPR-based channel sounders, our design eases the requirements on the data link between the USRP and the host, limits the measurement data size, and increases the signal-to-noise
Cities have been wildly successful over recent years in positioning themselves at the center of the global conversation on climate change. For example, the Intergovernmental Panel on Climate Change (IPCC) recently convened the Cities & Climate Change Conference (CitiesIPCC) in Edmonton, Alberta. The conference — hosted by a city that once advertised itself as Canada’s oil capital — brought tog
In December 2015, more than 190 nation-states adopted the Paris Agreement at the 21st Conference of the Parties to the United Nations FrameworkConvention on Climate Change (UNFCCC). This widely celebrated event hasspurred great enthusiasm among experts concerned with the globalresponse to climate change. Since then, considerable progress has beenachieved on the international level, especially at t
BACKGROUND: Transmission of coronavirus disease 2019 (COVID-19) can occur through inhalation of fine droplets or aerosols containing infectious virus. The objective of this study was to identify situations, patient characteristics, environmental parameters, and aerosol-generating procedures (AGPs) associated with airborne severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus.METHODS:
Loss of appetite and negative energy balance are common features of endotoxemia in all animals and are thought to have protective roles by reducing nutrient availability to host and pathogen metabolism. Accordingly, fasting and caloric restriction have well-established anti-inflammatory properties. However, in response to reduced nutrient availability at the cellular and organ levels, negative ene
Navigation with terrestrial wireless infrastructure is appealing to overcome geometrical limitations of satellite navigation for users in environments with limited sky views. However, terrestrial signals are also prone to multipath that can result in angular and range estimates that are not representative of actual transmitter-receiver geometry. In this paper, some of these propagation effects are
Realistic prediction of the near-future response of Arctic Ocean primary productivity to ongoing warming and sea ice loss requires a mechanistic understanding of the processes controlling nutrient bioavailability. To evaluate continental nutrient inputs, biological utilization, and the influence of mixing and winter processes in the Laptev Sea, the major source region of the Transpolar Drift (TPD)
