Wireless Recording of Cortical Activity by an Ion-Sensitive Field Effect Transistor.

Wireless brain technologies are empowering basic neuroscience and clinical neurology by offering new platforms that minimize invasiveness and refine possibilities during electrophysiological recording and stimulation. Despite their advantages, most systems require on-board power supply and sizeable transmission circuitry, enforcing a lower bound for miniaturization. Designing new minimalistic architectures that can efficiently sense neurophysiological events will open the door to standalone microscale sensors and minimally invasive delivery of multiple sensors.

Coronavirus Disease 2019 in the Emergency Department: Establishing an Interprofessional Incident Command System.

Coronavirus disease 2019 was declared a national emergency in the United States on March 13, 2020, at which time the Children's National Hospital Emergency Department in Washington, DC, mobilized to develop and implement a unit-based Incident Command System. Anticipating that the unique and challenging nature of this pandemic might require a large interprofessional team, emergency nurses, emergency physicians, and emergency physician assistants were placed in traditional Incident Command System roles to provide an organizational framework for the ED response. This framework served multiple purposes but most importantly it helped to efficiently streamline and coordinate communications within the emergency department, with hospital leadership and with other hospital departments.

Enhanced magnetic transduction of neuronal activity by nanofabricated inductors quantified via finite element analysis.

Methods for the detection of neural signals involve a compromise between invasiveness, spatiotemporal resolution, and the number of neurons or brain regions recorded. Electrode-based probes provide excellent response but usually require transcranial wiring and capture activity from limited neuronal populations. Noninvasive methods such as electroencephalography and magnetoencephalography offer fast readouts of field potentials or biomagnetic signals, respectively, but have spatial constraints that prohibit recording from single neurons.

Light-induced displacement of PLASTID MOVEMENT IMPAIRED1 precedes light-dependent chloroplast movements.

Light-dependent chloroplast movements are an actin-dependent cellular response to changes in the light environment that help plants maximize photosynthetic potential and reduce photodamage. Over a dozen proteins are known to be required for normal chloroplast movements, but the molecular mechanisms regulating the transformation of light perception into chloroplast motility are not fully understood. Here, we show that in Arabidopsis (Arabidopsis thaliana) the actin-bundling plasma membrane-associated proteins THRUMIN1, PLASTID MOVEMENT IMPAIRED1 (PMI1), and KINESIN-LIKE PROTEIN FOR ACTIN-BASED CHLOROPLAST MOVEMENT1 (KAC1) interact through the 14-3-3 proteins KAPPA and OMEGA.

Relational security: The impact of facility design on youth custodial staffs' practices and approaches.

Background: Constructive relationships between staff and young people in custody are a vital component of a therapeutic youth justice approach, which extends to the maintenance of a safe and secure environment (i.e., relational security).

Using the novel functional purchase task to examine prescription stimulant drug effect preferences in college students.

Nonmedical prescription stimulant use (NMPSU) is a rising trend among college-age adults (18-25 years old). Survey research has identified several reasons for use, including enhancing cognitive, athletic, and social performance. Less is known about how relative reinforcing value differs based on the self-reported reasons for use.

Light-dependent phosphorylation of THRUMIN1 regulates its association with actin filaments and 14-3-3 proteins.

Light-dependent chloroplast movements in leaf cells contribute to the optimization of photosynthesis. Low-light conditions induce chloroplast accumulation along periclinal cell surfaces, providing greater access to available light, whereas high light induces movement of chloroplasts to anticlinal cell surfaces, providing photodamage protection and allowing more light to reach underlying cell layers. The THRUMIN1 protein is required for normal chloroplast movements in Arabidopsis (Arabidopsis thaliana) and has been shown to localize at the plasma membrane and to undergo rapid light-dependent interactions with actin filaments through the N-terminal intrinsically disordered region (IDR).

Validation of "Personal Protective Equipment Conservation Strategies Tool" to Predict Consumption of N95s, Facemasks, and Gowns During Pandemic-Related Shortages.

We sought to prospectively validate a model to predict the consumption of personal protective equipment in a pediatric emergency department during the COVID-19 pandemic. We developed the Personal Protective Equipment Conservation Strategies Tool, a Monte Carlo simulation model with input parameters defined by members of our emergency department personal protective equipment task force. Inputs include different conservation strategies that reflect dynamic reuse policies.

Beliefs related to health care incentives: Comparison of substance use disorder treatment providers, medical treatment providers, and a public sample.

This study surveyed substance use disorder (SUD) treatment providers, medical treatment providers, and a public sample about beliefs regarding health care incentives to explore differences among the groups and across health disorders for which research has demonstrated incentives improve outcomes. Six hundred participants (n = 200/group) completed the Provider Survey of Incentives. The study found between group differences for positive and negative beliefs.

Behavior-Analytic Approaches to the Management of Diabetes Mellitus: Current Status and Future Directions.

Diabetes mellitus is the seventh leading cause of death in the United States, requiring a series of complex behavior changes that must be sustained for a lifetime (e.g., counting carbohydrates, self-monitoring blood glucose, adjusting insulin).

Self-Winding Helices as Slow-Wave Structures for Sub-Millimeter Traveling-Wave Tubes.

We present a transformative route to obtain mass-producible helical slow-wave structures for operation in beam-wave interaction devices at THz frequencies. The approach relies on guided self-assembly of conductive nanomembranes. Our work coordinates simulations of cold helices (i.
