Abstract
Background

Trans women have also been shown to experience disproportionately poor outcomes in physical and mental health. Although it is common to talk about the violence against trans people, little is still known about mental health outcomes and experiences of suicidality among trans women, particularly in developing countries. This study aims to investigate risk factors and associations with mental health, suicide ideation and suicide attempts among trans women in the largest metropolitan area in Brazil.
Methods

We surveyed 763 adult trans women living in São Paulo between May 2017 and July 2019. Multivariate regression models were used to investigate the associations with K10 score classification (logistic) and suicidal ideation/suicide attempt (ordinal logistic).
Results

Over one quarter of trans women had been diagnosed with anxiety in the past, and close to one in five trans women had received a diagnosis of depression. More than two in five trans women had moderate to severe psychological distress. More than half of all participating trans women reported having previously either experienced suicidal ideation or attempted to take their own lives. In multivariate regression, moderate to severe psychological distress was correlated with homelessness, income, current sex work, use of stimulant drugs, history of physical abuse, depression diagnosis and access to mental health treatment. Suicidal ideation and suicide attempts were correlated with race, living arrangements, marital status, current sex work, history of sexual violence, depression and PTSD diagnoses, access to mental health treatment and psychological distress.
Conclusions

This study showed that there is a clear association between mental health conditions, lack of treatment for these conditions and suicidality among trans gender women. This is the largest published empirical study of trans women’s mental health outcomes and related socioeconomic risk factors in Brazil and, to our knowledge, one of the largest worldwide.

Abstract
Background: Previous studies discuss the positive predictive value through whether the bacteria are coagulase-negative staphylococci. The view may need to be updated. The aim was to evaluate the positive predictive value of different bacteria species isolated from cerebrospinal fluid cultures and discuss the rationality to view coagulase-negative staphylococci as a group.Methods: This retrospective cohort study recruit all adults with positive cerebrospinal fluid cultures sampled by lumbar puncture 2012-2020 in the Department of Neurosurgery. The exposure was bacteria species, and the outcome was positive predictive value. An episode was defined as a patient with one bacteria. When episodes with a bacteria species reached five, the bacteria species was analyzed specifically. The positive predictive value was defined as the incidence of isolated-bacteria-related infected episodes. The isolated-bacteria-related infected episode was defined as the patient was with clinical features of bacterial meningitis, and the improvement was related to sensitive antibacterial agents. Then the differences of the positive predictive value of different bacteria in all specific bacteria species, coagulase-negative staphylococci, and non-coagulase-negative staphylococci bacteria were calculated, respectively. The results were statistically significant when P-value <.05.Results: 1180 episodes from 1133 patients with 79 bacteria were studied; the positive predictive value was 54.3%. The bacteria included 67 bacteria species, ten bacteria genus, viridans streptococci, and unclassified coagulase-negative staphylococci. Twenty-four specific bacteria species were analyzed. The range of positive predictive values of them was 29.4%-100.0% (P<.0001). The positive predictive value for Enterobacter aerogenes, Pseudomonas aeruginosa, Enterobacter cloacae, and Klebsiella oxytoca was the highest, while the positive predictive value for Staphylococcus cohnii was the lowest. Moreover, 767 (65.0%) were with coagulase-negative staphylococci, the positive predictive value was 46.4%, and the range was 29.4%-85.7% (P=.0020); 413 (35.0%) were with non-coagulase-negative staphylococci bacteria, the positive predictive value was 69.0%, and the range was 40.0%-100.0% (P<.0001).Conclusions: This study suggests that the positive predictive value of different bacteria species is different. It is more reasonable to discuss the positive predictive value of bacteria isolated from cerebrospinal fluid cultures through the bacteria species rather than whether they are coagulase-negative staphylococci.Trial registration: This is a retrospective study without interventions on participants.

Published: July 2021

Abstract
With reference to the limitations of YOLOv3 in recognizing symbols on Zhuang pattern, such as slow detection speed, unable to detect small object, and inaccurate positioning of bounding box, we propose a new model: Earf-YOLO (Efficient Attention Receptive Field You only look once) in this paper. In EarF-YOLO, we present an attention module: CBEAM (Convolution Block Efficient Attention Module) at first, which provides feature maps from channel and spatial dimensions. In CBEAM module, a local cross-channel interaction strategy without reducing dimensionality is used to improve the performance of the convolutional neural network. Besides, we put forward the SRFB (Strength Receptive Field Block) structure. During its training, more branch structures will be generated to enrich the feature space of the convolutional block. During its prediction, the multi-branched structures will be reparametrized and fused into one main branch to improve the performance of the model. Finally, we adopt some advanced training techniques to improve the detection performance. Experiments on the dataset of Zhuang patterns and the COCO dataset show that the Earf-YOLO model can effectively reduce the error of the prediction box and the ground-truth box, and decrease the calculation time. The mAP value of this model on the dataset of Zhuang patterns and on the COCO dataset reaches 82.1 (IoU=0.5) and 62.14 (IoU=0.5) respectively.

Abstract
Aqueous aluminum-ion batteries (AAIBs) are potential candidates for large-scale energy storage devices for their advantages of high energy density, resource abundance, low cost, safety, and environmental friendliness. Due to various redox procedures, good reversibility, and high discharge potential, the aqueous aluminum-manganese oxide battery has drawn wide attention, while the critical issues induced from slow kinetics and undesired soluble Mn2+ lead to slow charging, poor rate capability, and low energy density. However, there is very limited progress for performance improvement via conventional chemical or physical modification approaches. To overcome these challenges, an efficient photo-regulation strategy has been proposed in terms of direct radiating visible light on the cell during the galvanostatic charging and discharging. The efficient separation and transmission of photoelectrons in the photo positive electrode dramatically improves the dynamics, and fast charging and enhanced rate performance could be achieved. Photo-oxidation behavior can effectively promote the conversion of soluble Mn2+, thus further enhancing the energy density of the as-assembled aluminum-manganese battery. Furthermore, a photo-conversion efficiency of up to 1.2% has been acquired. Based on the photo-regulation strategy, the mechanism of the photoelectrochemical coupling system has been understood, which opens a promising route for achieving photoelectrochemical batteries with high energy density and fast charge.
Major Effective-damping Reduction Achieved by Metallic Coating on YIG Thin Films

Published: July 2021

Abstract
Since its discovery, yttrium iron garnet (YIG) has been object of great interest because of its peculiarly low magnetic damping. Magnetic materials with reduced damping promote microwave power efficiency, longer magnon lifetime and longer spin-wave propagation. Owing to research on charge-to-spin current conversion, the control of magnetic damping in ferromagnetic thin films has recently been achieved by inducing charge current on adjacent metal layer with strong spin-orbit coupling (SOC). We report damping reduction in metallized YIG thin films (YIG/Ag/Ni) without the need of applied charge current and suggest that the origin of this unexpected effect is a strengthening of the FMR uniform mode in the YIG layer, due to frequency- and phase-locking that result from self-synchronization mediated by nonzero spin densities transiting the metallic layers.

Abstract
Improvement of glucose and insulin sensitivity remains an unmet medical need in diabetes management, in which the underlying cause of type 2 diabetes(T2D) was not well addressed by current treatment. We report the findings of a randomized, double-blind, placebo-controlled, phase 3 clinical trial (NCT03173391) to evaluate the efficacy and safety of dorzagliatin, a dual-acting glucokinase (GK) allosteric modulator, which enhances the GK activity in T2D patients in a glucose dependent manner, and has demonstrated its effects in blood glucose control through improvement of glucose sensitivity in T2D patients. Eligible drug-naïve T2D patients (n=463) were randomly assigned to dorzagliatin group or placebo group in a 2:1 ratio for a 24-week double-blind treatment, then followed by a 28-week open-label treatment with dorzagliatin in all patients. The primary efficacy endpoint was the change from baseline in the glycated hemoglobin (HbA1c) level at week 24. Safety was assessed throughout the trial. At week 24, the change from baseline in HbA1c was -1.07% in the dorzagliatin group and -0.50% with placebo (ETD, -0.57%; 95%CI, -0.79 to -0.36; P<0.001), and the effects sustained through 52 weeks. Improvement of β-cell function was demonstrated by an increase of HOMA2-β in dorzagliatin group over placebo group (2.56 vs -0.72; 95% CI, 0.44 to 6.11; P<0.05) at week 24. The incidence of adverse events(AEs) was similar between the two groups during the 24 weeks and most AEs were mild during 52 weeks. There were no severe hypoglycemia events and drug related serious adverse events. The incidence of hypoglycemia was 1 of 310 patients (0.3%) in the dorzagliatin group during the 24 weeks. There was no body weight gain during the study period. In drug-naïve T2D patients, dorzagliatin demonstrated fast onset and sustained glycemic control with a good safety and tolerability profile for 52 weeks.
SARS-CoV-2 spike protein 13-mer subdomain corresponds to the drug-binding domain of glutamyl-propyl-tRNA synthetase 1 and is targetable by halofuginone
Authors: Benoit Lora , Shenoy Vinayak , Meykler Simon , Mohseni Ali 
Published: July 2021

Abstract
Since its emergence, SARS-CoV-2 has been the subject of intense investigation. Early sequence analysis identified a unique 13 amino acid region (13-mer) nested within the receptor-binding domain (RBD) of the spike protein that directly interacts with the ACE2 receptor. Blasting with the 13-mer identified a highly conserved segment in propyl-tRNA synthetase enzymes. Comparison with the human analogue, glutamyl-propyl-tRNA synthetase 1, showed a high level of identity with its drug binding domain, which is targeted by halofuginone, a drug recently shown to block SARS-CoV-2 infection in vitro. In silico experiments predicted a high affinity interaction between halofuginone and the 13-mer. In vitro addition of halofuginone effectively inhibited binding of recombinant S1 monomer to ACE2. Accordingly, it appears that halofuginone inhibits viral infection by preventing correct interactions between spike protein and ACE2. These findings indicate that viral entry can potentially be drug-targeted and support the application of halofuginone in mitigation of COVID-19.
The impact of ambient pressure and tunnel inclination angle on the smoke transport in a subway tunnel
Authors: Chen Guang 
Published: July 2021

Abstract
The subway tunnel will be built in the plateau where the pressure is relatively low, and the tunnel will tilt at a certain angle due to topographic factors. In order to investigate the smoke transport characteristics of moving subway trains caught fire under different ambient pressures and different tunnel inclination angles, three-dimensional full-scale calculation models of subway trains, two stations and one tunnel are established, and three different environmental pressures (50kPa, 75kPa, 100kPa) and three different tunnel inclination angles (− 1.5 °, 0 °, + 1.5 °) are simulated. The IDDES turbulence model based on kω-sst RANS combined with the overset grid technology is used to simulate the subway train movement and the detailed flow field. The velocity and temperature distribution characteristics and smoke concentration field are studied in detail. The soot density of smoke and temperature increases with reduced ambient pressure due to the weakening of air entrainment and the decreased air density and the influence of ambient pressure on smoke diffusion decreases with the increase of pressure. The longitudinal airflow induced by the stack effect under the negative inclination angle of the tunnel is helpful to prevent the flowing back of smoke.

The Role of Ethnicity in Expression, Prevalence, and Severity of Generalized Anxiety Disorder and their Overlap with Depressive Symptoms: Epidemiological Evidence from a Rapidly Developing Middle Eastern Country
Authors: Khaled Salma M. , Zolezzi Monica 
Published: July 2021

Abstract
IntroductionQatar is a small but high-income Middle Eastern country with a large influx of migrants each year. However, the impact of changing population structure and urbanization on prevalence of generalized anxiety symptoms remains unexplored to date. Materials & MethodsA total of 2,640 participants interviewed by phone using the Generalized Anxiety Disorder (GAD-7) and the Patient Health Questionnaire (PHQ-2). Bivariate and multinomial logistic regression analyses were conducted to explore the associations of ethnicity (Arab versus Non-Arab) with severity and symptom profile of GAD and overlap with depressive symptoms. ResultsThe point prevalence of mild, moderate, and severe symptoms were 13.4% (95% CI: 11.9 – 15.0), 2.7% (95% CI: 2.0 – 3.5), and 0.9% (95% CI: 0.6– 1.4), respectively. Arab ethnicity was associated with mild GAD (OR=1.78, p=0.009) and moderate-to-severe GAD (OR=2.36, p=0.044). Relative to non-migrants, migrant types were not significantly associated with mild or with moderate-to- severe GAD. Interactions between depressive symptoms and ethnicity were evident and statistically significant for the association with mild GAD versus no GAD (OR=0.34, p=0.003). ConclusionsEthnicity moderated the association of depression symptoms and GAD severity, with potential implications for early screening and community intervention.

Published: July 2021

Abstract
The importance of water recovery and reuse is increasing day by day. Therefore, the use of advanced technologies is applied for the treatment and recovery of textile wastewater. The fact that ceramic membranes are resistant to the challenging characteristics of textile wastewater makes the use of ceramic membranes useful. Within the scope of this review, general information about the textile industry and treatment techniques are mentioned, as well as the properties of ceramic membranes and textile wastewater treatment. In the literature review made in this study, recent studies on the production of ceramic membranes and laboratory applications have been compiled. However, it has been observed that although the real-scale studies are relatively higher in industries such as the food and petrochemical industry, it is rather limited in the textile industry.

Published: July 2021

AbstractKitchen waste from hotels and homes is one of the major problems for urban and rural environment and could be one of the best sources of renewable energy by producing biogas through anaerobic digestion. A research work was undertaken to assess the methane potential of kitchen waste at different total solids (TS) content. Kitchen wastes such as spoiled rice, brinjal, potato, papaya, tomato, fish and poultry parts etc., which are easily decomposed, were selected for this study. Batch experiments were set up under ambient temperature. Kitchen waste was added to the batch digester at different TS content (5, 7, 10, 12 and 15%) and sealed for 146 days until the gas production stopped. Substrate characteristics were analyzed before and after the anaerobic digestion. The highest methane yield was 78.12 L/kg VS at 15% TS content followed by 12, 10, 7 and 5%. Different kinetic parameters were determined using a logistic model and the model showed a good fit with the experimental results. After modelling using Minitab®, the optimum TS content for kitchen waste was found to be 14.90%.
User Experiences of the NZ COVID Tracer App in New Zealand: Thematic Analysis of Interviews
Authors: Tretiakov Alexei , Hunter Inga 
Published: July 2021

Background
For mobile app–based COVID-19 contact tracing to be fully effective, a large majority of the population needs to be using the app on an ongoing basis. However, there is a paucity of studies of users, as opposed to potential adopters, of mobile contact tracing apps and of their experiences. New Zealand, a high-income country with western political culture, was successful in managing the COVID-19 pandemic, and its experience is valuable for informing policy responses in similar contexts.

Objective
This study asks the following research questions: (1) How do users experience the app in their everyday contexts? and (2) What drives the use of the app?

Methods
Residents of New Zealand’s Auckland region, which encompasses the country’s largest city, were approached via Facebook, and 34 NZ COVID Tracer app users were interviewed. Interview transcripts were analyzed using thematic analysis.

Results
Interviews ranged in duration from 15 to 50 minutes. Participants ranged in age from those in their late teens to those in their early sixties. Even though about half of the participants identified as White New Zealanders of European origin, different ethnicities were represented, including New Zealanders of South Pacific, Indian, Middle Eastern, South American, and Southeast Asian descent. Out of 34 participants, 2 (6%) identified as Māori (Indigenous New Zealanders). A broad range of careers were represented, from top-middle management to health support work and charity work. Likewise, educational backgrounds ranged broadly, from high school completion to master’s degrees. Out of 34 participants, 2 (6%) were unemployed, having recently lost their jobs because of the pandemic. The thematic analysis resulted in five major themes: perceived benefits, patterns of use, privacy, social influence, and need for collective action. Benefits of using the app to society in general were more salient to the participants than immediate health benefits to the individual. Use, however, depended on the alert level and tended to decline for many participants at low alert levels. Privacy considerations played a small role in shaping adoption and use, even though the participants were highly aware of privacy discourse around the app. Participants were aware of the need for high levels of adoption and use of the app to control the pandemic. Attempts to encourage others to use the app were common, although not always successful.

Conclusions
Appeals to civic responsibility are likely to drive the use of a mobile contact tracing app under the conditions of high threat. Under the likely scenario of COVID-19 remaining endemic and requiring ongoing vigilance over the long term, other mechanisms promoting the use of mobile contact tracing apps may be needed, such as offering incentives. As privacy is not an important concern for many users, flexible privacy settings in mobile contact tracing apps allowing users to set their optimal levels of privacy may be appropriate.
