Updated Review of the Evidence Supporting the Medical and Legal Use of NeuroQuant and NeuroGage in Patients With Traumatic Brain Injury.

Over 40 years of research have shown that traumatic brain injury affects brain volume. However, technical and practical limitations made it difficult to detect brain volume abnormalities in patients suffering from chronic effects of mild or moderate traumatic brain injury. This situation improved in 2006 with the FDA clearance of NeuroQuant, a commercially available, computer-automated software program for measuring MRI brain volume in human subjects.

Determination of the ^{27}Al Neutron Distribution Radius from a Parity-Violating Electron Scattering Measurement.

Organo-Nanocups Assist the Formation of Ultra-Small Palladium Nanoparticle Catalysts for Hydrogen Evolution Reaction.

Ultra-small palladium nanoparticles were synthesized and applied as catalysts for a hydrogen evolution reaction. The palladium metal precursor was produced via beta-cyclodextrin as organo-nanocup (ONC) capping agent to produce ultra-small nanoparticles used in this study. The produced ~3 nm nanoparticle catalyst was then characterized via X-ray diffraction (XRD), transmission electron microscopy (TEM), ultraviolet-visible spectroscopy (UV-Vis), and Fourier transform infrared spectroscopy (FTIR) to confirm the successful synthesis of ~3 nm palladium nanoparticles.

Bereavement in Pakistan during the COVID-19 pandemic: Psychometric analysis of the Pandemic Grief Scale-Urdu Version (PGS-UV).

With nearly 4 million deaths worldwide, COVID-19 has resulted in a great loss of life. For many of the bereaved, the grieving process has been especially difficult due to COVID-19 spatial distancing procedures and the traumatic circumstances of this particular form of loss. Consequently, a large number of the world's bereaved are experiencing dysfunctional levels of grief.

Form Factors and Two-Photon Exchange in High-Energy Elastic Electron-Proton Scattering.

We present new precision measurements of the elastic electron-proton scattering cross section for momentum transfer (Q^{2}) up to 15.75  (GeV/c)^{2}. Combined with existing data, these provide an improved extraction of the proton magnetic form factor at high Q^{2} and double the range over which a longitudinal or transverse separation of the cross section can be performed.

Multidimensional, High Precision Measurements of Beam Single Spin Asymmetries in Semi-inclusive π^{+} Electroproduction off Protons in the Valence Region.

High precision measurements of the polarized electron beam-spin asymmetry in semi-inclusive deep inelastic scattering (SIDIS) from the proton have been performed using a 10.6 GeV incident electron beam and the CLAS12 spectrometer at Jefferson Lab. We report here a high precision multidimensional study of single π^{+} SIDIS data over a large kinematic range in Bjorken x, fractional energy, and transverse momentum of the hadron as well as photon virtualities Q^{2} ranging from 1-7  GeV^{2}.

Global plant diversity as a reservoir of micronutrients for humanity.

With more than two billion people suffering from malnutrition and diets homogenizing globally, it is vital to identify and conserve nutrient-rich species that may contribute to improving food security and diversifying diets. Of the approximately 390,000 vascular plant species known to science, thousands have been reported to be edible, yet their nutritional content remains poorly characterized. Here we use phylogenetic information to identify plants with the greatest potential to support strategies alleviating B-vitamin deficiencies.

Stop talking about it already! Co-ruminating and social media focused on COVID-19 was associated with heightened state anxiety, depressive symptoms, and perceived changes in health anxiety during Spring 2020.

Background: Social distancing presents a significant obstacle for relationships and threatens mental health. Identifying maladaptive, voluntary coping strategies may inform how to maintain interpersonal relationships and mental health during quarantine. Co-ruminating with peers on negative events, moods and fears has adjustment trade-offs of increasing depression and anxiety risk while also enhancing friendship quality.

Improved Λp Elastic Scattering Cross Sections between 0.9 and 2.0 GeV/c as a Main Ingredient of the Neutron Star Equation of State.

Strange matter is believed to exist in the cores of neutron stars based on simple kinematics. If this is true, then hyperon-nucleon interactions will play a significant part in the neutron star equation of state. Yet, compared to other elastic scattering processes, there is very little data on Λ-N scattering.

The times they are a-changin':Teaching and learning beyond COVID-19.

The COVID-19 pandemic has forced teachers to incorporate many changes to support student learning. In this paper, we present current research focusing on the impact of the changes brought by the pandemic on teachers. Specifically, we discuss the current state of teachers after working the frontline of the pandemic and changes that school leaders and policymakers should consider moving forward.

Point Absorber Limits to Future Gravitational-Wave Detectors.

High-quality optical resonant cavities require low optical loss, typically on the scale of parts per million. However, unintended micron-scale contaminants on the resonator mirrors that absorb the light circulating in the cavity can deform the surface thermoelastically and thus increase losses by scattering light out of the resonant mode. The point absorber effect is a limiting factor in some high-power cavity experiments, for example, the Advanced LIGO gravitational-wave detector.

Chloride intracellular channel 4 (CLIC4) expression profile in the mouse medial prefrontal cortex and its regulation by ethanol.

Background: Chloride intracellular channel 4 (CLIC4) is a multifunctional metamorphic protein for which a growing body of evidence supports a major role in the brain's molecular and behavioral responses to ethanol (EtOH). Although key to understanding the functional biology underlying this role, little is known about the cellular and subcellular expression patterns of CLIC4 in brain and how they are affected by EtOH.

Methods: We used qRT-PCR to assess Clic4 mRNA expression in the medial prefrontal cortex (mPFC) of C57BL/6J mice in the absence and presence of acute EtOH exposure.

Teaching during a Pandemic: United States Teachers' Self-Efficacy During COVID-19.

The COVID-19 pandemic had significant implications on schools during 2020, with districts moving to all virtual instruction during the spring and facing the debate of how to return safely to school in the fall. With these decisions, teachers, schools, and districts faced many challenges when providing face-to-face, hybrid, and virtual teaching. The purpose of this study was to explore how the new teaching approaches and requirements have impacted teachers' self-efficacy, specifically instructional and engagement efficacy.

Spirituality Influences Emotion Regulation During Grief Talk: The Moderating Role of Prolonged Grief Symptomatology.

A growing body of research demonstrates that religion greatly affects people's adjustment to loss. However, little is known about the influence of religiosity on emotion regulation during grief. The present study attempts to fill this void in the literature by examining the predictive relationship between variables assessing facets of religiosity and emotion regulation during an interview about loss in a sample of bereaved adults.

The Psychometric Properties of the Stress and Anxiety to Viral Epidemics-6 Items: A Test in the U.S. General Population.

Many individuals around the world are suffering from psychological distress due to the COVID-19 outbreak. The aim of this study is to explore the validity and reliability of the English version of Stress and Anxiety to Viral Epidemics-6 (SAVE-6), which measures the anxiety response of the general population to the viral epidemic. A cross-sectional web-based study with self-reporting measures was conducted.

Chaotic Entanglement: Entropy and Geometry.

In chaotic entanglement, pairs of interacting classically-chaotic systems are induced into a state of mutual stabilization that can be maintained without external controls and that exhibits several properties consistent with quantum entanglement. In such a state, the chaotic behavior of each system is stabilized onto one of the system's many unstable periodic orbits (generally located densely on the associated attractor), and the ensuing periodicity of each system is sustained by the symbolic dynamics of its partner system, and vice versa. Notably, chaotic entanglement is an entropy-reversing event: the entropy of each member of an entangled pair decreases to zero when each system collapses onto a given period orbit.

Deep Exclusive Electroproduction of π^{0} at High Q^{2} in the Quark Valence Regime.

We report measurements of the exclusive neutral pion electroproduction cross section off protons at large values of x_{B} (0.36, 0.48, and 0.

A Fading Affect Bias First: Specific Healthy Coping with Partner-Esteem for Romantic Relationship and Non-Relationship Events.

The Fading Affect Bias (FAB) is the faster fading of unpleasant affect than pleasant affect. Research suggests that the FAB is an indicator of general healthy coping, but it has not shown consistent specific healthy coping via differential relations of the FAB to individual differences across event types. Although previous research did not find specific healthy coping for the FAB across romantic relationship events, these researchers did not include non-relationship control events.

Risk factors for dysfunctional grief and functional impairment for all causes of death during the COVID-19 pandemic: The mediating role of meaning.

The COVID-19 pandemic, coupled with significant social changes due to legislative and public health requirements, has changed the way in which people experience grief. We examined whether dysfunctional grief symptoms, disrupted meaning, risk factors, and functional impairment differed between people bereaved from COVID-19 and from other natural or violent causes in this same period. A sample of 409 participants (67.

Perineuronal Nets and Metal Cation Concentrations in the Microenvironments of Fast-Spiking, Parvalbumin-Expressing GABAergic Interneurons: Relevance to Neurodevelopment and Neurodevelopmental Disorders.

Because of their abilities to catalyze generation of toxic free radical species, free concentrations of the redox reactive metals iron and copper are highly regulated. Importantly, desired neurobiological effects of these redox reactive metal cations occur within very narrow ranges of their local concentrations. For example, synaptic release of free copper acts locally to modulate NMDA receptor-mediated neurotransmission.
