An mHealth Intervention to Improve Pre-Exposure Prophylaxis Knowledge Among Young Black Women in Family Planning Clinics: Development and Usability Study

Background Young Black women between the ages of 18 and 24 years are disproportionately impacted by HIV, yet they have a low self-perception of HIV risk and limited exposure to prevention strategies. Pre-exposure prophylaxis (PrEP) is a safe and effective biomedical HIV prevention strategy for those at risk for HIV infection, but uptake has been slow among cisgender women. Family planning clinics are a primary source of health care access for young women, providing an ideal opportunity to integrate PrEP information and care into existing clinic practices. Objective The aim of this study was to use a multistage, community-engaged process to develop a mobile health app and to evaluate the feasibility and acceptability of the app. Methods Using user-centered design, the In the Loop app was developed in collaboration with a community advisory board of young Black women. This study employed a multistage design, which included community-engaged app development, user testing, and evaluation of the app’s feasibility and acceptability. A pre- and postdesign was used to assess the impact of the app on PrEP knowledge immediately after app use. Descriptive statistics (eg, mean, SD, and percentage values) were used to describe the sample, and Wilcoxon matched-pairs signed-ranks test was used to detect changes in PrEP knowledge before and immediately after using the app. Results A total of 50 sexually active, young Black women, aged 18-24 (mean 21, SD 1.9) years, were enrolled in this study. Analysis comparing scores before and immediately after use of the app revealed a significant increase in PrEP content knowledge scores on a 7-item true or false scale (z=–6.04, P<.001). Overall, participants considered the In the Loop app feasible and acceptable to use while waiting for a family planning visit. The majority of participants (n=46, 92%) agreed that they would recommend In the Loop to friends to learn more about PrEP. Participants rated the overall quality of the app 4.3 on a 1-5 scale (1=very poor and 5=very good). Of 50 participants, 40 (80%) agreed that the app was easy to use, and 48 (96%) agreed that they found the information in the app easy to understand. Finally, 40 (80%) agreed that they had enjoyed using the app while waiting for their family planning visit. Conclusions Our findings suggest that young Black women waiting for family planning visits found the In the Loop app to be feasible and acceptable. This study demonstrates the value of engaging young Black women in the app design process. As family planning clinics are a primary source of health care access for young women, they provide an ideal setting to integrate PrEP information and care into existing clinic practices. Next steps in the development of the In the Loop app include implementing user-suggested improvements and conducting efficacy testing in a randomized controlled trial to determine the app’s impact on PrEP uptake.
A Tool for Long-Term Forest Stand Projections of Swedish Forests

The analysis of forest management strategies at landscape and regional levels forms a vital part of finding viable directions that will satisfy the many services expected of forests. This article describes the structure and content of a stand simulator, GAYA, which has been adapted to Swedish conditions. The main advantage of the GAYA implementation compared to other resources is that it generates a large number of management programmes within a limited time frame. This is valuable in cases where the management programmes appear as activities in linear programming (LP) problems. Two methods that are engaged in the projections, a climate change response function and a soil carbon model, are designed to complement other methods, offering transparency and computational effectiveness. GAYA is benchmarked against projections from the Heureka system for a large set of National Forest Inventory (NFI) plots. The long-term increment for the entire NFI set is smaller for GAYA compared with Heureka, which can be attributed to different approaches for modelling the establishment of new forests. The carbon pool belonging to living trees shows the same trend when correlated to standing volume. The soil carbon pool of GAYA increases with increased standing volume, while Heureka maintains the same amount over the 100-year projection period.
PWM Control Techniques for Single-Phase Multilevel Inverter Based Controlled DC Cells

This paper presents a single-phase five-level inverter controlled by two novel pulse width modulation (PWM) switching techniques. The proposed PWM techniques are designed based on minimum switching power loss and minimum total harmonic distortion (THD). In a single-phase five-level inverter employing six switches, the first proposed PWM technique requires four switches to operate at switching frequency and two other switches to operate at line frequency. The second proposed PWM technique requires only two switches to operate at switching frequency and the rest of the switches to operate at line frequency. Compared with conventional PWM techniques for single-phase five-level inverters, the proposed PWM techniques offer high efficiency and low harmonic components in the output voltage. The validity of the proposed PWM switching techniques in controlling single-phase five-level inverters to regulate load voltage is verified experimentally using a 100 V, 500 W laboratory prototype controlled by dspace 1103.
Influence of cyclic variance on The Performance of URANS for Pulsating Flow upstream of an Automotive Catalyst Monolith

CFD predictions using the URANS equations have been compared to phase-averaged and instantaneous PIV pulsating flow fields in a planar diffuser upstream of a catalyst monolith. URANS qualitatively capture the velocity and vorticity fields, in particular the spatial and temporal evolution of the main vortices in the diffuser during the acceleration phase of the cycle. However, they over-predict vortex intensity and hence its residual strength at the beginning of successive pulses. Instantaneous PIV measurements show there is a significant cycle-to-cycle variation in the position and structure of the vortices within the diffuser. This serves to "diffuse" the phase-averaged vortex strength. Alternative simulation techniques such as LES or DNS will be needed if the cyclic variation is to be correctly predicted as this will affect conversion efficiency.
A Review of the Role of Workplace Spirituality and Organizational Citizenship Behavior in Enhancing Corporate Sustainability: An Underpinning Role of Stern and Dietz’s Value Model

Organizations are under pressure to explore innovative sustainability practices that will enable organizations to handle the deteriorating issues of biodiversity and social inequality. Stern and Dietz’ model offered a set of values with which organizations can create sustainability. This study’s main purpose was to explore how Stern and Dietz’ model underpin the various dimensions of workplace spirituality and organizational citizenship behavior to accomplish corporate sustainability. To achieve the objective of the study, the previous literature was reviewed to construct a conceptual framework. This conceptual model is comprised of three phases egoistic, social altruistic, and biospheric. Based on prior literature, various dimensions of workplace spirituality and organizational citizenship behavior were underpinned to accomplish corporate sustainability. Even though this concept sets out basic guidelines. However relevant knowledge should be regarded in order to reconcile these steps in different instances. This article provides a systematic review of the Stern and Dietz value model to achieve various aspects of organizational sustainability. A constructive framework was developed to create corporate sustainability by incorporating workplace spirituality and organizational citizenship behavior into the context of the Stern Dietz’ value model. Theoretical and practical implications are also discussed in this study.
Subgroup Analysis in Pulmonary Hypertension-Specific Therapy Clinical Trials: A Systematic Review

Pulmonary hypertension (PH) treatment decisions are driven by the results of randomized controlled trials (RCTs). Subgroup analyses are often performed to assess whether the intervention effect will change due to the patient’s characteristics, thus allowing for individualized decisions. This review aimed to evaluate the appropriateness and interpretation of subgroup analyses performed in PH-specific therapy RCTs published between 2000 and 2020. Claims of subgroup effects were evaluated with prespecified criteria. Overall, 30 RCTs were included. Subgroup analyses presented: a high number of subgroup analyses reported, lack of prespecification, and lack of interaction tests. The trial protocol was not available for most RCTs; significant differences were found in those articles that published the protocol. Authors reported 13 claims of subgroup effect, with 12 claims meeting four or fewer of Sun’s criteria. Even when most RCTs were generally at low risk of bias and were published in high-impact journals, the credibility and general quality of subgroup analyses and subgroup claims were low due to methodological flaws. Clinicians should be skeptical of claims of subgroup effects and interpret subgroup analyses with caution, as due to their poor quality, these analyses may not serve as guidance for personalized care.

Time-Correction Model Based on Diverter Speed for a pVTt Gas Flow Primary Standard

The volumetric primary standard with a constant volume (pVTt) determines the flow rate from the rate of change of gas density in the defined measuring volume. The key element of the measuring system that uses the flying start–stop method is a diverter. This paper presents a time correction model that adapts the correction according to the diverting speed implemented in our pVTt system developed for flow rates smaller than 12mgmin−1. A detailed study of the diverter’s effects on the effective collection time and two methods for determining the time correction are presented. One is based on the ISO 4185 standard and the other on measurements of the dynamic pressure upstream of the diverter. A set of correction time measurements were made at different diversion speeds to define the correction model at a flow rate of 9mgmin−1. The results show very good agreement between the measurements with both methods and the defined correction model. Additional measurements were made at smaller flow rates and the results indicate the independence of the time correction from the measured flow rate.
HY.POWER - A Fuel Cell Car Boosted with Supercapacitors

Fuel cell cars are generally accepted as very promising approach to the solution of future environmental and energy issues. In order to reduce emissions, improve urban air quality and in view of the declining oil reserves hydrogen/methanol made from renewable sources such as biomass or solar must be the future fuel. Without fuels made from renewable sources the contribution of EV and HEV to the solution of environmental problems is of second order. Fuel cells (FC) can exhibit the highest energy density of all electrochemical energy storage and conversion devices; therefore the FC is well suited to provide sufficient energy for vehicles with a high range. However FCs are limited in power density and are not capable of energy recuperation. Therefore it appears to be straightforward to combine the FC with a second, high power, intermediate storage device such as supercapacitors (SC, electrochemical Double-Layer Capacitors will be called supercapacitors throughout this paper) or a high power battery. The implementation of a second storage device allows reducing the size and cost of the FC and provides extra power during acceleration, improving driving comfort. With a booster device the FC can operate most of the time at moderate power, which increases its efficiency and thus results in fuel savings. Finally, depending on the actual driving mode, recuperation of braking energy will also contribute to fuel savings. The question as to whether a short term storage device is needed and whether a capacitor or a battery is the optimum choice for the intermediate storage device will be answered in the future most probably on a cost basis /1, 2/. For HY.POWER technology platform presented in this paper, capacitors were considered to be the better choice. Recuperation of braking energy is a main argument for using a second storage device combined with a fuel cell. Fuel consumption of a HEV varies depending on the driving cycle and the weight of the vehicle. Figure 1 shows the fuel consumption for several American, European and Japanese driving cycles. It is evident that during urban cycles more fuel is consumed than on the high way. The fuel consumption was calculated for a small (750 kg) and a large (1500 kg) car and does not vary significantly with the weight of the car. The corresponding theoretical fuel savings potential with energy recuperation are also shown in Figure 1. Recuperation energy of up to 20 % can be used for an urban driving cycle with many stop-and-goes.
Detecting Large Explosions With Machine Learning Models Trained on Synthetic Infrasound Data

Explosions produce low‐frequency acoustic (infrasound) waves capable of propagating globally, but the spatio‐temporal variability of the atmosphere makes detecting events difficult. Machine learning (ML) is well‐suited to identify the subtle and nonlinear patterns in explosion infrasound signals, but a previous lack of ground‐truth data inhibited training of generalized models. We introduce a physics‐based method that propagates infrasound sources through realistic atmospheres to create 28,000 synthetic events, which are used to train ML classifiers. A simple artificial neural network and modern temporal convolutional network discriminate synthetic events from background noise with >90% accuracy and, more importantly, successfully identify the majority of real‐world explosion signals recorded during the Humming Road Runner experiment. ML models trained entirely on physics‐based synthetics advance explosion detection capabilities and make ML more viable to related fields lacking training data.

Non-Alcoholic Components in Huangjiu as Potential Factors Regulating the Intestinal Barrier and Gut Microbiota in Mouse Model of Alcoholic Liver Injury

Different alcoholic beverages and drinking patterns might exert divergent impacts on alcoholic liver disease (ALD) progression. Whether the abundant non-alcoholic components (NAC) in fermented wine could alleviate ethanol (EtOH)-induced adverse influences on the liver remains unknown. Hence, the chronic ALD mouse model was established to compare the effects of Huangjiu (a typical fermented wine) and EtOH feeding on the liver, intestinal barrier, gut microbiota, and intestinal short-chain fatty acids (SCFAs) content. Although Huangjiu intake led to slight hepatic steatosis, it mitigated oxidative stress, inflammation, and intestinal damage relative to EtOH intake. In comparison with EtOH feeding, Huangjiu significantly improved the intestinal barrier integrity and reduced hepatic lipopolysaccharide levels by up-regulating the expression of intestinal tight junction proteins (ZO-1 and occludin) and antimicrobial activity peptides (Reg3β and Reg3γ). The administration of Huangjiu NAC partially restored alcohol-induced gut microbiota dysbiosis via recovering the abundance of Lactobacillus, Faecalibaculum, and Akkermansia. Moreover, mice receiving Huangjiu showed higher SCFAs levels (such as acetic acid and butyric acid) than those receiving EtOH. Huangjiu consumption resulted in lower hepatotoxicity than pure EtOH, at the same alcohol dose. The NAC in Huangjiu might attenuate the progression of ALD by regulating intestinal barrier function and microbiota-meditated gut ecology.
Unwinding on the Weekend from Work-Related Stress: Moderating Effect of Weekday Psychological Stress on the Relationship between Increased Recovery Experience and Reduction of Psychological Stress on the Weekend

Recovery is described as a process that is in contrast to the process whereby the psychological stress response increases. Recovery experiences refer to specific experiences that promote recovery and represent psychological attributes including relaxation. This preliminary study tested the hypothesis that levels of psychological stress before the weekend have a moderating effect on the relationship between an increased recovery experience during the weekend and a reduction of psychological stress from workdays to the weekend. Of 270 Japanese teachers who were invited to participate, 181 completed questionnaires on the psychological stress response before, on the psychological stress response and the recovery experience during the weekend. Data from 7 part-time teachers and 38 teachers who were not stressed at all before the weekend were excluded; therefore, data for 136 participants were ultimately analyzed. Results of hierarchal regression analysis indicated that increased relaxation was associated with an increased reduction in psychological stress response during the weekends in participants with high levels of psychological stress before the weekends. This moderating effect was not observed for other recovery experiences. Considering the psychological stress response is important for research on recovery experiences during weekends.
