Differentiating neural sensitivity and bias during face-emotion processing in youth: a computational approach.

The ability to interpret face-emotion displays is critical for the development of adaptive social interactions. Using a novel variant of a computational model and fMRI data, we examined behavioral and neural associations between two metrics of face-emotion labeling (sensitivity and bias) and age in youth. Youth and adults (n = 44, M age = 20.

All-Electrical Driving and Probing of Dressed States in a Single Spin.

The subnanometer distance between tip and sample in a scanning tunneling microscope (STM) enables the application of very large electric fields with a strength as high as ∼1 GV/m. This has allowed for efficient electrical driving of Rabi oscillations of a single spin on a surface at a moderate radiofrequency (RF) voltage on the order of tens of millivolts. Here, we demonstrate the creation of dressed states of a single electron spin localized in the STM tunnel junction by using resonant RF driving voltages.

Synthesis of SiO@Ag Nanocomposite for Investigating Metal-Enhanced Fluorescence and Surface-Enhanced Raman Spectroscopy.

SiO@Ag nanocomposite (NC) has been synthesized by the chemical reduction and Stӧber method for Metal-enhanced fluorescence (MEF) of Rhodmine 6G (R6G) and Surface-enhanced Raman spectroscopy (SERS) of Malachite green (MG). As-synthesized SiO@Ag NC indicated SiO nanosphere (NS) and Ag nanoparticle (NP) morphologies. The SiO@Ag NC was high quality with a well-defined crystallite phase with average sizes of 24 nm and 132 nm for Ag NP and SiO NC, respectively.

Data-driven prediction of the shear capacity of ETS-FRP-strengthened beams in the hybrid 2PKT-ML approach.

A new approach that combines analytical two-parameter kinematic theory (2PKT) with machine learning (ML) models for estimating the shear capacity of embedded through-section (ETS)-strengthened reinforced concrete (RC) beams is proposed. The 2PKT was first developed to validate its representativeness and confidence against the available experimental data of ETS-retrofitted RC beams. Given the deficiency of the test data, the developed 2PKT was utilized to generate a large data pool with 2643 samples.

Electric-Field-Driven Spin Resonance by On-Surface Exchange Coupling to a Single-Atom Magnet.

Coherent control of individual atomic and molecular spins on surfaces has recently been demonstrated by using electron spin resonance (ESR) in a scanning tunneling microscope (STM). Here, a combined experimental and modeling study of the ESR of a single hydrogenated Ti atom that is exchange-coupled to a Fe adatom positioned 0.6-0.

Double-Resonance Spectroscopy of Coupled Electron Spins on a Surface.

Scanning-tunneling microscopy (STM) combined with electron spin resonance (ESR) has enabled single-spin spectroscopy with nanoelectronvolt energy resolution and angstrom-scale spatial resolution, which allows quantum sensing and magnetic resonance imaging at the atomic scale. Extending this spectroscopic tool to a study of multiple spins, however, is nontrivial due to the extreme locality of the STM tunnel junction. Here we demonstrate double electron-electron spin resonance spectroscopy in an STM for two coupled atomic spins by simultaneously and independently driving them using two continuous-wave radio frequency voltages.

Examining the Relations Between Children's Vagal Flexibility Across Social Stressor Tasks and Parent- and Clinician-Rated Anxiety Using Baseline Data from an Early Intervention for Inhibited Preschoolers.

Early behavioral inhibition (BI) is a known risk factor for later anxiety disorder. Variability in children's parasympathetic nervous system (PNS) functioning may provide insight into the substantial heterogeneity in anxiety outcomes for children high in BI. However, gaps persist due to an over-reliance on static measures of functioning, which limits our ability to leverage PNS functioning to identify risk for anxiety.

Examining teachers' behavioural intention for online teaching after COVID-19 pandemic: A large-scale survey.

Recently, the coronavirus disease 2019 (COVID-19) pandemic has led to rapid digitalisation in education, requiring educators to adopt several technologies simultaneously for online learning and teaching. Using a large-scale survey ( = 1740), this study aims to construct a model that predicts teachers' extensive technology acceptance by extending the Technology Acceptance Model (TAM) with their technological pedagogical content knowledge (TPACK) and innovativeness. TAM has been a valuable tool to measure the adoption of new technology in various contexts, including education.

Our goals for this commentary include synthesizing the articles, highlighting common themes, and suggesting future research initiatives involving measurement, developmental, and cultural considerations.

Reduction in Sporadic Norovirus Infections Following the Start of the COVID-19 Pandemic, 2019-2020, Philadelphia.

Introduction: Norovirus infections are common in the USA and worldwide. Detection of norovirus in fecal samples is now common in routine tests for enteric pathogens using molecular methods. We observed a change in positivity rates for norovirus after the beginning of the coronavirus disease 2019 (COVID-19) pandemic in our laboratory and performed a more detailed analysis of testing results.

Computational Modeling of Attentional Impairments in Disruptive Mood Dysregulation and Attention-Deficit/Hyperactivity Disorder.

Objective: Computational models provide information about cognitive components underlying behavior. When applied to psychopathology-relevant processes, they offer additional insight to observed differences in behavioral performance. Drift diffusion models have been successfully applied to investigate processing efficiency during binary choice tasks.

The Clinician Affective Reactivity Index: Validity and Reliability of a Clinician-Rated Assessment of Irritability.

Irritability is impairing in youth and is the core feature of disruptive mood dysregulation disorder (DMDD). Currently, there are no established clinician-rated instruments to assess irritability in pediatric research and clinical settings. Clinician-rated measures ensure consistency of assessment across patients and are important specifically for treatment research.

Airway smooth muscle cells are insensitive to the anti-proliferative effects of corticosteroids: The novel role of insulin growth factor binding Protein-1 in asthma.

Airway remodeling in asthma manifests, in part, as enhanced airway smooth muscle (ASM) mass, due to myocyte proliferation. While the anti-proliferative effects of glucocorticoid (GC) were investigated in normal ASM cells (NASMC), little is known about such effects in ASM cells derived from asthma subjects (AASMC). We posit that GC differentially modulates mitogen-induced proliferation of AASMC and NASMC.

Group Effects on Individual Attitudes Toward Social Responsibility.

This study uses a quasi-experimental design to investigate what happens to individual socially responsible attitudes when they are exposed to group dynamics. Findings show that group engagement increases individual attitudes toward social responsibility. We also found that individuals with attitudes toward social responsibility are likely to change their opinions when group members show more positive attitudes toward social responsibility.

A new approach involving a multi transducer ultrasonic system for cleaning turbine engines' oil filters under practical conditions.

The purpose of this paper is to provide a green technology that can clean turbine engine oil filters effectively in ships using ultrasound, with ultrasonic devices having a frequency of 25kHz and different powers of 300W and 600W, respectively. The effects of temperature, ultrasonic cleaning times, pressure losses through the oil filter, solvent washing, and ultrasonic power devices were investigated. In addition, the cleaning efficiency of three modes (hand washing, preliminary washing and ultrasonic washing) were compared to assess their relative effectiveness.

Adaptation to Externally Driven Change: The Impact of Political Change on Job Satisfaction in the Public Sector.

This article uses a quasi-natural experiment to investigate the adaptation of job satisfaction to externally driven political change in the public sector. This is important because democratic government bureaucracies often experience changes in leadership after elections. The analyses are based on data drawn from a large longitudinal data set, the British Household Panel Survey.

Capillary compared to venous blood sampling in clozapine treatment: patients׳ and healthcare practitioners׳ experiences with a point-of-care device.

Underuse of the antipsychotic clozapine for schizophrenia is an impediment to improving outcomes for patients. Because of its possible severe side effects, including granulocytopenia or even agranulocytosis, clozapine treatment entails regular WBC monitoring, which can be a major drawback for patients and practitioners. The HemoCue WBC DIFF system is a point-of-care device using capillary blood sampling which provides WBC counts with differentials, including granulocytes.

Dynamics of serum testosterone during the menstrual cycle evaluated by daily measurements with an ID-LC-MS/MS method and a 2nd generation automated immunoassay.

Background: Testosterone concentrations in normally cycling women are assumed to be elevated around the time of ovulation. The clinical relevance of changing testosterone concentrations during the menstrual cycle, however, is unclear. Poor performance of current direct immunoassays for testosterone at low concentrations confounds this issue.

Salivary testosterone in female-to-male transgender adolescents during treatment with intra-muscular injectable testosterone esters.

Introduction: In our hospital, female-to-male (FtM) transgender adolescents from the age of 16 are treated with two- or four-weekly intra-muscular injections of testosterone-esters. Some patients treated with four-weekly injections have complaints of fatigue and experience mood swings towards the end of the inter-injection period, which calls for an evaluation of the time-course of testosterone levels between injections. Evaluation of salivary testosterone is a practical approach for sequential measurements.
