AbstractLight‐emitting field‐effect transistors (LEFETs) are emerging optoelectronic devices able to display simultaneously electrical switching as transistors and electroluminescence emission as light emitting diodes. Lead chalcogenide colloidal quantum dots (CQDs) allow achieving light emission in a very broad spectral range, covering the near‐infrared (NIR) and the short‐wavelength infrared (SWIR) regions, which cannot be reached with other solution‐processable materials. Therefore, the use of lead chalcogenide CQDs as active layer in LEFETs opens the possibility for very narrow and switchable light sources in the NIR and SWIR range. The recently reported, first fully solid‐state lead chalcogenide (PbS) CQD based LEFET shows an electroluminescence (EL) quantum efficiency of 1.3 × 10−5 at room temperature and of about 1% below 100 K. To overcome the limits of a previous report, an active material comprising two sequentially deposited layers is designed, the first of PbS CQDs displaying n‐type transport and the second of polymer‐wrapped semiconducting carbon nanotubes displaying p‐type dominated transport. With this double layer system, LEFETs displaying a well‐balanced ambipolar transport, charge carrier mobility of about 0.2 cm2 V−1 s−1 for both electrons and holes, and EL external quantum efficiency reaching 1.2 × 10−4 at room temperature are obtained.

Published: February 2022

AbstractAcid–base transport is integral to many important interfacial reactions in various fields of chemistry, but its theoretical foundation is lacked. Herein, a common acid–base transport model is established owing to the success in deriving buffer transport equations. This model is applicable to most buffer systems by flexibly integrating the transport equations in terms of buffer components, and is verified through the model relationships of buffer transport limiting current by using hydrogen evolution reaction experiments. Based on model calculations, two diagram approaches are proposed to depict the dynamic pH response and aid buffer operation optimizations. The model and methods allow us to quantify the rate‐limiting effect of acid–base transport on interfacial reactions and to precisely control the effect through medium regulations. Furthermore, the model has laid the foundation of dynamic pH effect on species transformation and process mechanism, which can be of wide interest in the chemistry encompassing interfacial reactions.

AbstractIntroductionThis longitudinal study determined if social cognitive variables influence physical activity in girls stratified on the basis of maturity status.MethodsParticipants attended South Carolina public schools (Mage in 5th grade = 11.1 years) and included a cohort of 529 girls who provided physical activity data in the 5th grade and in 6th and/or 7th grade. The measure of maturity status was age at peak height velocity (APHV) estimated from maturity offset when the children were in the 5th grade. The Earlier Maturity (EM) group included girls whose APHV was one standard deviation or more below the mean APHV for the full sample. All other girls were placed in the Later Maturity (LM) group. Physical activity was assessed at each time point via accelerometry. Social‐cognitive variables were assessed at each time point by a questionnaire measuring self‐efficacy, enjoyment, competence, appearance, fitness, and social motives for physical activity. Growth curves for the total, Earlier Maturing, and Later Maturing groups assessed relationships between physical activity over time and time‐varying social cognitive variables.ResultsPhysical activity was lower in the Earlier Maturing group and was positively associated with self‐efficacy and enjoyment motivation in the total group. These relationships were observed in the 5th grade and maintained through 7th grade. In the Later Maturing group, we observed positive relationships between physical activity and self‐efficacy, enjoyment and competence motivation.ConclusionsStrategies to increase confidence, skills, and enjoyment of physical activity may only be effective for promoting activity among later maturing girls.
The apathy, gait impairment, and executive dysfunction (AGED) triad vascular variant

Published: February 2022

AbstractApathy, gait disturbances, and executive dysfunction (AGED) often occur together. Although they can arise independently, the presence of one might portend another. This recognition suggests the possible etiology. We focus on the most common, the vascular. We explain the AGED vascular mechanism through the ambibaric brain concept. The brain contains two complementary blood pressure systems: One high in the primitive brain (brainstem, basal ganglia, and thalamus) and a low‐pressure system in the Homo sapiens brain (cerebral hemispheres). Hypertension inflicts the most damage on the primitive brain. The frontal systems connect to the basal ganglia, then the thalamus and back to the cortex. Many connections converge on the primitive brain where they are damaged by vascular disease. We need methods of determining optimal, individual blood pressures. Although the AGED triad can result from other causes, it should first signal a vascular etiology, the most prevalent, treatable, and preventable one.

AbstractBackgroundThe Omicron (B.1.1.529) SARS‐COV‐2 variant has raised serious concerns because of its unprecedented rapid rate of spreading and the fact that there are 36 mutations in the spike protein. Since the vaccine‐induced neutralizing antibody targets are the spike protein, this may lead to the possibility of vaccine‐induced humoral immunity escape.MethodsWe measured the neutralizing activity in vitro for Omicron and compared this with wild type (WH‐09) and Delta variants in human and monkey sera from different types of immunity. The monkey sera samples were collected at 1 and 3 months post three‐dose inactivated (PiCoVacc) and recombinant protein (ZF2001) vaccination. Human sera were collected from 1 month post three‐dose inactivated vaccination.ResultsIn inactivated vaccine sera, at 1/3 months post three‐dose, geometric mean titers (GMTs) of neutralization antibody (NAb) against the Omicron variant were 4.9/5.2‐fold lower than those of the wild type. In recombinant protein vaccine sera, GMTs of NAb against Omicron were 15.7/8.9‐fold lower than those of the wild type. In human sera, at 1 month post three‐dose inactivated vaccination, GMTs of NAb against Omicron were 3.1‐fold lower than those of the wild type.ConclusionThis study demonstrated that despite a reduction in neutralization titers, cross‐neutralizing activity against Omicron and Delta variants was still observed after three doses of inactivated and recombinant protein vaccination.

Published: February 2022

ABSTRACTDegenerative lumbar disease is a common condition in which progressive deterioration of the structures in the spine causes severely incapacitating pain and disability. Conservative management, including passive or active physical therapy, activity modification, and medications (eg, anti‐inflammatory medications, oral and injectable steroids, opioids), may provide relief. However, when conservative management is unsuccessful or patients experience symptoms for an extended period of time, they may require spine surgery. Surgeons use a variety of techniques to perform lumbar fusion procedures with instrumentation, including open, percutaneous, minimally invasive, and robotic‐assisted with navigation. The accuracy of pedicle‐screw placement varies according to the technique used, and accuracy rates are high after robotic‐assisted with navigation procedures. In addition, robotic‐assisted spine procedures result in fewer infections than non–robotic‐assisted spine procedures (P = .04). Perioperative nurses should understand basic lumbar spine anatomy, steps completed during robotic‐assisted lumbar spine surgery, and the nursing considerations for patients undergoing this type of procedure.

The role of depressive symptoms between neighbourhood disorder, criminal justice contact, and suicidal ideation: Integrating an ecological stress model with General Strain Theory
Authors: Oh Gyeongseok , Connolly Eric J. 
Published: February 2022

AbstractBackgroundWhile much literature has examined the independent effect of perceived neighbourhood disorder on criminal behaviour and/or mental disorder, comparatively little is known about the role of depressive symptoms on these associations over time.AimsOur aim was to examine whether depressive symptoms mediate association between perceived neighbourhood disorder, future criminal justice contact, and future suicidal ideation.MethodsWe grounded this research in primary arguments derived from General Strain Theory (GST). Data were drawn from structured self‐reports in surveys of over 2000 young adult participants from the Children of the National Longitudinal Survey of Youth, who are the offspring born to the women from the National Longitudinal Survey of Youth 1979. Information on neighbourhood disorder and depressive symptoms were used from the 2012 data collection period, while information on criminal justice contact and suicidal ideation were drawn from the 2014 period. Structural equation modelling was used to examine both direct and indirect pathways between neighbourhood disorder, depression, contact with the justice system, and suicidal ideation from 2012 to 2014.ResultsDepressive symptoms were found to partially mediate the effect of perceived neighbourhood disorder on future criminal justice contact, with the strength of this effect varying across categories of race/ethnicity. The association between perceived neighbourhood disorder and suicidal ideation was fully mediated by depressive symptoms.Conclusions and implicationsOur findings are consistent with an ecological stress framework integrated with arguments from GST to understand the associations between neighbourhood disorder, criminal justice contact, and severe mental illness. Future research is needed on gender and racial/ethnic pathways. The reported findings suggest that, in addition to neighbourhood improvements, ready access to mental health services could not only reduce the risk of suicide but support safer communities.

AbstractUm die Wärmeübertragung bei der Kondensation von Wasserdampf zu intensivieren, wurden neuartige Wärmeübertrager‐Rohre mit zweifachen Oberflächenmodifikationen entwickelt: Außenseitig wird das Rohr hydrophob beschichtet, um eine verbesserte Tropfenkondensation zu erzielen; innenseitig wird die Turbulenz durch den Einsatz eines Drallrohrs intensiviert. Das Kondensationsverhalten auf der Außenseite eines modifizierten Einzelrohrs wird experimentell untersucht. Die Ergebnisse zeigen eine signifikante Intensivierung des Wärmeübergangs.
The linear Lasso: A location model approach
Authors: Fraser D. A. S. , Bédard Mylène 
Published: February 2022

AbstractWe use location model methodology to guide the least squares analysis in the Lasso problem of variable selection and inference. The nuisance parameter is taken to be an indicator for the selection of explanatory variables, and the interest parameter is the response variable itself. Recent theory eliminates the nuisance parameter by marginalization on the data space and then uses the resulting distribution for inference concerning the interest parameter. We develop this approach and find that primary inference is essentially one‐dimensional rather than n‐dimensional, inference focuses on the response variable itself rather than the least squares estimate (as variables are removed), computation is relatively easy, a scalar marginal model is available, and ineffective variables can be removed by distributional tilt or shift.

Published: February 2022

AbstractObjectiveSatisfaction with normative life domains has been proposed as an important factor in the persistence of anorexia nervosa (AN). Initial evidence from a cross‐sectional study indicated that individuals with AN reported lower satisfaction with normative life domains than individuals without an eating disorder. As an important next step in understanding causal relations, the present study used a longitudinal design to examine whether an improvement in AN symptoms is paralleled by an increase in satisfaction with normative life domains from baseline to follow‐up and whether relatively low satisfaction with normative life domains at baseline is related to less improvement in AN symptoms.MethodsDuring baseline and at 1‐year follow‐up, adolescents with AN (N = 69) completed the Brief Multidimensional Students' Life Satisfaction Scale to measure satisfaction with normative life domains (e.g., friendships, school experience). Furthermore, eating disorder symptoms and BMI were measured.ResultsImprovement in eating disorder symptoms, but not in BMI, was paralleled by an increase in satisfaction with normative life domains. Relatively low satisfaction with normative life domains at baseline was not prospectively related to less improvement in eating disorder symptoms or BMI at follow‐up.DiscussionOur findings provide initial evidence that satisfaction with normative life domains is a malleable factor which fluctuates with symptom severity in AN. The results of this exploratory study point to the relevance of examining whether targeting satisfactory engagement with specific life domains optimizes treatment effectiveness.Public SignificanceWe explored whether an improvement in anorexia nervosa symptoms from start of treatment to 1‐year follow‐up would be paralleled by an increase in satisfaction with normative life domains. Improvement in eating disorder symptoms (but not BMI) was indeed related to a concurrent increase in satisfaction with normative life domains. These preliminary results point to the promising possibility that targeting satisfactory engagement with specific life domains may potentially enhance treatment effectiveness.

Published: February 2022

AbstractObjectiveJust‐in‐time adaptive interventions (JITAIs), momentary interventions delivered at identified times of risk, may improve skill utilization during cognitive‐behavioral therapy (CBT‐E) for bulimia‐spectrum eating disorders (BN‐EDs). JITAIs may be especially helpful for individuals with self‐regulation deficits, including emotion regulation deficits and elevated impulsivity.MethodParticipants (N = 55 with BN‐EDs) received 16 sessions of CBT‐E with electronic self‐monitoring and were randomized to receive JITAIs (JITAIs‐On) or not receive JITAIs (JITAIs‐Off). Baseline Difficulties in Emotion Regulation Scale (DERS) and UPPS‐P Impulsive Behavior Scale (UPPS‐P) total scores were examined as moderators of baseline to post‐treatment change in binge episodes, compensatory behaviors, and Eating Disorder Examination (EDE) global score using repeated measures ANOVAs.ResultsEmotion regulation difficulties significantly moderated compensatory behavior change (F[1, 51] = 4.31, p = .04, ηp2 = 0.08) such that individuals with emotion regulation deficits demonstrated greater improvements in the JITAIs‐On condition. Impulsivity moderated change in binge episodes (F[1, 51] = 8.94, p = .004, ηp2 = 0.15) and compensatory behaviors (F[1, 51] = 7.83, p = .007, ηp2 = 0.13), such that individuals with high impulsivity showed greater improvement in the JITAIs‐On condition. Neither DERS nor UPPS‐P scores moderated EDE global score change.DiscussionJITAIs appear particularly beneficial for facilitating skill use during treatment for BN‐EDs for individuals with self‐regulation deficits, yielding improved treatment outcomes.Public Significance StatementReminders to use therapy skills that are delivered via smartphone as an individual goes about their daily life may improve treatment response among individuals with bulimia nervosa who have difficulty coping with emotions or who tend to act impulsively. Results from this study indicate that individuals with these difficulties benefitted more from cognitive‐behavioral therapy when it was accompanied by in‐the‐moment reminders to use therapeutic skills, which may facilitate long‐term recovery.Clinical Trials.gov Registration NumberNCT03673540.
What is next for cases in teaching and learning evaluation? A call to action

Published: February 2022

AbstractWe take this final article to reflect on the “case” made for the use of cases in teaching and learning in evaluation. We provide an overview of what has been learned about teaching and learning with cases through this volume and discuss what counts as good case teaching and learning based on the other articles. This article identifies the critical importance of context in evaluation practice and shares our belief that there is no way we can adequately prepare future evaluation practitioners for their work without using cases in teaching and learning evaluation. We share the future efforts of the Case Collaborative, including the development and dissemination of a case repository for instructors of evaluation. We end by reflecting on how we can get new evaluators to think like professional, seasoned practitioners and providing a call to action to our readers.

AbstractGold nanoparticles associated with DNA, RNA, proteins, oligonucleotides, and peptides are useful in therapies and drug delivery. The present article mainatins that gold nanoparticles play a tremendous role in remedying cancer and fatal diseases. A mathematical model is proposed for the two‐dimensional motion of the couple stress nanofluid consisting of gold nanoparticles under the application of peristaltic propulsion and electroosmosis mechanisms in an asymmetric microchannel. The effects of radiation with slip boundary have been employed. The governing equations are simplified under the assumptions of low Reynolds number and long wavelength and the Poisson‐Boltzmann equation is solved under Debye–Hückel linearization. Analytical solutions for the velocity of fluid motion, nanoparticle temperature, stream function, pressure gradient, are evaluated and analyzed graphically under the effects of various physical parameters. It is notable from the analysis that raising the Brinkman number boosts the nanoparticle temperature and heat transfer coefficient which validate the physical model and analysis. Moreover, it is noticed that sphere‐shaped gold nanoparticles enhance the temperature as compared to other geometries of nanoparticles. The present study results may assist in developing the technology, smart micropumps, drugs, and device for hemodialysis and other health care applications.

AbstractObjectiveStress‐related symptoms are associated with significant health and economic burden. Several studies suggest Nx4 for the pharmacological management of the stress response and investigated the underlying neural processes. Here we hypothesized that Nx4 can directly affect the stress response in a predefined stress network, including the anterior cingulate cortex (ACC), which is linked to various stress‐related symptoms in patients.MethodsIn a randomized, placebo‐controlled, double‐blind, crossover trial, 39 healthy males took a single dose of placebo or Nx4. Psychosocial stress was induced by the ScanSTRESS paradigm inside an MRI scanner, and stress network activation was analyzed in brain regions defined a priori.ResultsUsing the placebo data only, we could validate the activation of a distinct neural stress pattern by the ScanSTRESS paradigm. For Nx4, we provide evidence of an attenuating effect on this stress response. A statistically significant reduction in differential stress‐induced activation in the right supracallosal ACC was observed for the rotation stress task of the ScanSTRESS paradigm. The results add to previously published results of Nx4 effects on emotion regulation.ConclusionsOur results strengthen the hypothesis that Nx4 modulates the stress response by reducing the activation in parts of the neural stress network, particularly in the ACC.Trial registration: NCT02602275; ClinicalTrials.gov
