Effects of Physical Activity and Circadian Rhythm Differences on the Mental Health of College Students in Schools Closed by COVID-19

Purpose: Since the prolonged sequestration management that was implemented in order to achieve lower infection and mortality rates, there has been a surge in depression worldwide. The correlation between the physical activity level and the detection rate of a depressed mood in college students should be of wide concern. A large number of studies have focused on the association between physical activity levels and a negative mood, but circadian rhythm differences seem to be strongly associated with both physical activity levels and mental illness. Therefore, this paper will examine the correlation between physical activity levels, circadian rhythm differences, and mental health levels in college students. METHODS: Data were collected through a web-based cross-sectional survey. In June and December 2022, questionnaires were administered to college students from three universities in Anhui, China. In addition to socio-demographic information, measures included the International Physical Activity Questionnaire-Short Form (IPAQ-SF), Morning and Evening Questionnaire-5 Items (MEQ-5), and Symptom Check List90 (SCL-90) scales. Correlation analysis was used to understand the relationship between physical activity and circadian rhythm differences in the three aspects of college student’s mental health. RESULTS: The analysis of the data led to the conclusion that 28.4% of the 1241 college students in this survey had psychological disorders. The physical activity level of male students was higher than that of female students, but the risk of having depressive tendencies was higher in female students than in male students. There was a significant negative correlation between the physical activity level and scl-90 scores (p < 0.01), which indicates that higher physical activity levels are associated with higher mental health. Circadian rhythm differences and scl-90 scores were significantly positively correlated among college students (p < 0.01), and night-type people had a higher risk of mental illness than intermediate-type and early-morning-type people. CONCLUSIONS: During the period of closed administration due to COVID-19, school college students experienced large and high levels of negative emotional phenomena due to reduced physical activity and public health emergencies. This study showed significant correlations between both physical activity levels and circadian rhythmicity differences and the degree of mental health of college students.
High Drug Resistance Levels Compromise the Control of HIV Infection in Pediatric and Adult Populations in Bata, Equatorial Guinea

A lack of HIV viral load (VL) and HIV drug resistance (HIVDR) monitoring in sub-Saharan Africa has led to an uncontrolled circulation of HIV-strains with drug resistance mutations (DRM), compromising antiretroviral therapy (ART). This study updates HIVDR data and HIV-1 variants in Equatorial Guinea (EG), providing the first data on children/adolescents in the country. From 2019–2020, 269 dried blood samples (DBS) were collected in Bata Regional Hospital (EG) from 187 adults (73 ART-naïve/114 ART-treated) and 82 children/adolescents (25 HIV-exposed-ART-naïve/57 ART-treated). HIV-1 infection was confirmed in Madrid by molecular/serological confirmatory tests and ART-failure by VL quantification. HIV-1 pol region was identified as transmitted/acquired DRM, predicted antiretroviral susceptibility (Stanfordv9.0) and HIV-1 variants (phylogeny). HIV infection was confirmed in 88.1% of the individuals and virological failure (VL > 1000 HIV-1-RNA copies/mL) in 84.2/88.9/61.9% of 169 ART-treated children/adolescents/adults. Among the 167 subjects with available data, 24.6% suffered a diagnostic delay. All 125 treated had experienced nucleoside retrotranscriptase inhibitors (NRTI); 95.2% were non-NRTI (NNRTI); 22.4% had experienced integrase inhibitors (INSTI); and 16% had experienced protease inhibitors (PI). At sampling, they had received 1 (37.6%), 2 (32%), 3 (24.8%) or 4 (5.6%) different ART-regimens. Among the 43 treated children–adolescents/37 adults with sequence, 62.8/64.9% carried viruses with major-DRM. Most harbored DRM to NNRTI (68.4/66.7%), NRTI (55.3/43.3%) or NRTI+NNRTI (50/33.3%). One adult and one child carried major-DRM to PI and none carried major-DRM to INSTI. Most participants were susceptible to INI and PI. DRM was absent in 36.2% of treated patients with VL > 1000 cp/mL, suggesting adherence failure. TDR prevalence in 59 ART-naïve adults was high (20.3%). One-half (53.9%) of the 141 subjects with pol sequence carried CRF02_AG. The observed high rate of ART-failure and transmitted/acquired HIVDR could compromise the 95-95-95-UNAIDS targets in EG. Routine VL and resistance monitoring implementation are mandatory for early detection of ART-failure and optimal rescue therapy selection ART regimens based on PI, and INSTI can improve HIV control in EG.
EXPERIMENTAL AND THEORETICAL ASSESSMENT OF A DEVICE USED FOR EVALUATION OF BLAST AND FRAGMENTATION EFFECTS

An alternative to traditional momentum pendulum devices is sought to better resolve the time response to blast and fragmentation and protect the instrumentation from damage when positioned closely to the source of the blast. Evaluation concepts based on the use of strain gages have been used for some time in the scientific community. However, those devices either produce extensive parasitic oscillations or they are restricted for use in a close proximity to the source of the blast and during a short time only. An alternative design is suggested and analysed that can extend the record time to tens of milliseconds and can be used both in close proximity and at relatively large stand‐off distances from the source of the blast. The device employs conventional strain gauges that are safely protected from the blast and fragmentation. Numerical analysis points to the way to minimise the system oscillations, which was partly implemented in the present system.
Depression detection in social media comments data using machine learning algorithms

Depression is the next level of negative emotions. When a person is in a sad mood or going through a difficult situation and it is not leaving him and giving him pain continuously and he is unable to bear it anymore, that situation is called depression. The last stage of depression occurs in suicide. According to the World Health Organization (WHO), Currently, 4.4% of people in the world are currently suffering from depression. In 2021, fourteen thousand people committed suicide all over the world and the rating of suicide is increasing day by day. So, our study is to find depressed people by their comments, posts, or texts on social media. We collected almost 10,000 data from Facebook posts, comments, and YouTube comments. Data mining and machine learning (ML) algorithms make our work easier and play a big role in easily detecting a person’s emotions. We applied six classifiers to predict depression non-depression and found the best accuracy on a support vector machine (SVM).
Formalizing a Two-Step Decision-Making Process in Land Use: Evidence from Controlling Forest Clearcutting Using Spatial Information

In this paper, we examine a particular case of land use pattern: forest management activities facing an uncertainty related to spatial information signals received. We investigate the combination of two well-known theoretical approaches, the Blackwell theorem and entropy analysis, in providing a decision support framework for decision makers. We examine the uncertainty related to the information signals received within a decision support context and compute the optimal actions. Drawing on satellite imagery as an additional source of information provided by French spatial data infrastructure (SDI), we illustrate our approach through a clear-cutting control case study. The control of clear-cutting is a central issue in forest management. In order to perform an efficient control operation, uncertainty regarding the decisions to be taken needs to be minimized. Reducing uncertainty in a decision-making context related to forest management provides greater opportunities for improving productivity and for saving time and money. The results show that the information structure through the SDI signals has the most significant information power. Moreover, a maximum of two information structures can be compared when applying the Blackwell theorem. However, while using the entropy approach, a comparison of several information structures can be performed.
A Psychometric Investigation of Racial Trauma Symptoms Using a Semi-Structured Clinical Interview With a Trauma Checklist (UnRESTS)

The term racial trauma is used to describe the cumulative distressing and traumatizing effects of racism in all of its forms, and it closely resembles the construct of posttraumatic stress disorder (PTSD). This investigation aims to increase our understanding of racial trauma by comparing the characteristics of those with a clinically-relevant diagnosis of racial trauma to those without, based on the findings of a clinical semi-structured interview and symptom checklist for assessing racial trauma, the University of Connecticut Racial Ethnic Stress and Trauma Survey (UnRESTS), administered to a diverse group of adults (N = 97). This paper extends prior work on racial trauma by examining the correlations between racial trauma and validated self-report measures of discriminatory distress, controlling for racialization. We examine the correlation between a clinically-relevant diagnosis of racial trauma and racial/ethnic identity. We also compare racism-related PTSD symptoms in those with and without racial trauma to inform clinical assessment. Finally, we examine the factor structure of racial trauma symptoms using the 24 items from the UnRESTS PTSD symptom checklist and compare these to current DSM-5 models. The structure of racial trauma symptoms differed from the DSM-5 4-factor model, as do other PTSD models in the research literature. Clinical and research implications are discussed.
Market Integration and Price Transmission Analysis of Onion in Wholesale Markets of India

The present study was done in seven major onion wholesale markets in India, namely Pimpalgaon, Lasalgaon, Solapur, Pune, Bangalore, Hyderabad and Indore to explore the interdependence of wholesale prices amongst Indian onion markets. The study was conducted in all India perspective and the study period involves the seventeen years data of onion wholesale prices (January 2004 to December 2020). The study was majorly based on the prices of onion obtained through secondary source. These data were collected from various portals such as FAO, NHRDF, Agmarknet and NHB. The current study employs co-integration analysis of wholesale monthly onion prices in selected marketplaces to determine the degree of market integration. The Trace and Maximum Eigen-value tests results showed that the onion prices in India moves together in the long run equilibrium. As a result, it may be stated that India's onion markets are well-functioning. The direction of information flow was determined by using Granger Causality test. It was found that in few markets pairs, price transmissions were bi-directional whereas between Bangalore and Pune market, no transmission was found. The study reveals that Lasalgaon market is dominating in terms of price determination. The empirical study also recommends keeping a careful eye on diverse market behavioural patterns, since "news" in one market might have an influence on other markets due to the numerous interdependencies.
Multi-watt laser operation and laser parameters of Ho-doped Lu_2O_3 at 212 μm

We present spectroscopic investigations and the first laser operation of Ho:Lu2O3. Laser operation was obtained with two different setups at room temperature: In a 1.9 μm diode pumped setup a maximum output power of 15 W was achieved. With a Tm-fiber laser pumped setup the maximum output power was 5.2 W and the slope efficiency was 54% with respect to the absorbed pump power. Absorption measurements revealed absorption cross sections of up to 11.7 · 10−21 cm2 at 1928 nm. In the 2.1 μm range a maximum emission cross section of 4.5 · 10−21 cm2 at 2124 nm was determined, which remains the highest gain peak even for high inversions. The fluorescence lifetime of the 5I7-manifold was found to be 10 ms.
Factor Investing and ESG in the corporate bond market before and during the COVID-19 crisis

The objective of this paper is to illustrate the factor investing space in credit before and during the COVID-19 crisis and is an extension of our prior practitioner analysis on both the new alternative credit factors and the ESG integration in credit. We use monthly credit excess return in the EUR denominated Investment Grade bond universe for regression analysis and factor picking. ESG was making its way to becoming a mainstream factor within the Investment Grade universe and when the COVID-19 stress hit the financial markets, it displayed a “hedge-like” behavior. Better ESG leading to lower cost of capital has been documented previously, however the realization of this feature in a stress environment is worth investors’ attention.
A detailed study of the Lynds 1551 star formation region

The results of an optical spectroscopic and photometric study of the star formation region Lynds 1551 and the young stellar object IRS 5 and a high-resolution spectroscopic study of the Herbig-Haro (HH) objects associated with the outflow from this region are reported. The results further establish IRS 5 as the source of the reflected light in the region. Spectral studies suggest that the spectrum of IRS 5 is dominated by the light from an accretion disk analogous to those characterizing objects of the rare class of FU Orionis objects. Analysis of high and medium resolution spectra of the optical jet emanating from IRS 5 strongly suggest that the jet HH objects are the bow shock interfaces between two winds coming from the IRS 5 region. The high-velocity wind is inferred to have a velocity of 440 km/s, and is identified as the stellar wind. High-density clumps in the stellar wind shock a lower-density, but much more pervasive second wind which has an inferred velocity of about 160 km/s. 69 references.
Intersex child’s parents’ negative experiences – case study

Intersexualism is often treated as a secret in medical and family systems. According to the thesis that intersex body is pathological and requires immediate surgical and hormonal regulation, intersex persons are subject to the process which involves rapid production of normative masculinity or femininity through invasive clinical practices. The goal of the study was to diagnose the experiences of parents of an intersex child with searching for support during the treatment for both the child and themselves. The study was conducted by means of individual semi-structured interview. The results are presented as a case study. It was shown that parents do not always receive the necessary social and medical support, and their children are treated as sensations and pathologies, regardless of the fact that empathy and acceptance are critical for making the right treatment-related decisions.
Hierarchical surface rough ordered Au particle arrays and their surface enhanced Raman scattering

A simple, effective, and low-cost method is presented to fabricate an ordered Au particle array with hierarchical surface roughness on an indium tin oxide substrate based on an ordered alumina through-pore template, induced by solution dipping on colloidal monolayer, using an electrochemical deposition strategy. The array consists of periodically arranged and isolated Au microparticles, which show nanoscaled surface roughness. Importantly, this hierarchically rough particle array exhibits strong surface-enhanced Raman scattering effect using rhodamine 6G as probe molecules, associated with its surface geometry. Such structure could be useful, e.g., in sensors, biotechnology, and nanodevices.
Antibiotic Resistance of Helicobacter pylori in Patients with Peptic Ulcer

Background and Objectives: To determine the antibiotic resistance rate of H. pylori among patients with peptic ulcer. Materials and Methods: A cross-sectional monocentric study was conducted from January to December 2021 among patients aged from 16 years with gastrointestinal symptoms and esophagogastroduodenoscopy. Gastric mucosa biopsies were collected at the edges of the ulcer or at lesion sites for H. pylori culture. Five antibiotics (amoxicillin (AMX), clarithromycin (CLR), metronidazole (MTZ), levofloxacin (LEV), and tetracycline (TET)) were selected for antibiotic susceptibility testing. Results: One hundred and twenty-five patients were included, and the sex ratio was 0.6. Their mean age was 47.3 ± 14.2 years. All of the participants had gastritis, and 24.0% had duodenitis. A total of 21.6% of patients had a duodenal ulcer, and 12.8% had an antral ulcer. A total of 40 specimens have grown in H. pylori culture. The proportion of resistance to AMX, CLR, MTZ, LEV, and TET was 27.5%, 50%, 67.5%, 35%, and 5%, respectively. The proportion of multidrug resistance was 22.5%. The proportion of double resistance to AMX + CLR was 20.0%, AMX + MTZ was 15.0%, AMX + LEV was 2.5%, CLR + MTZ was 32.5%, and TET + MTZ was 5.0%. Conclusions: Our research results show that the treatment with MTX-TET or LVX-AMOX has the highest sensitivity rate. Therefore, practitioners should refer to these regimes to eradicate H. pylori in patients with gastric and duodenal ulcers. The reports on H. pylori eradication from different geographic areas show heterogeneous results. Therefore, continuous monitoring of antibiotic resistance of H. pylori in each population is very important. Having evidence helps clinicians to treat patients most effectively, reduce treatment costs, and limit the rate of antibiotic resistance.
Pricing of Equity Indexed Annuity under Fractional Brownian Motion Model

Fractional Brownian motion with Hurst exponent is a good candidate for modeling financial time series with long-range dependence and self-similarity. The main purpose of this paper is to address the valuation of equity indexed annuity (EIA) designs under the market driven by fractional Brownian motion. As a result, this paper presents an explicit pricing expression for point-to-point EIA design and bounds for the pricing of high-water-marked EIA design. Some numerical examples are given to illustrate the impact of the parameters involved in the pricing problems.
The association between adverse childhood experiences, self-silencing behaviours and symptoms in women with fibromyalgia

ABSTRACT Poor adult health has consistently been associated with Adverse Childhood Experiences (ACEs). The process is not fully understood but is likely to involve a complex interaction of biological and psychosocial factors. Early life stress can affect the developing brain resulting in long-term hyper-responses to stress and raised inflammatory biomarkers. Women with fibromyalgia syndrome (FMS) frequently report ACEs and also self-sacrificial behaviours whereby they repress their own needs and emotions to preserve personal relationships. This behavioural profile (termed self-silencing) may develop following ACEs but has not previously been considered in the context of FMS. This study examined whether self-silencing mediates the link between ACEs and FMS symptoms. Women with (N = 539) and without (N = 184) an FMS diagnosis completed measures of Silencing-the-Self, health symptoms and ACEs. Number of ACEs and symptom levels were significantly associated in both groups. One aspect of self-silencing, care and self-sacrifice (putting others needs before your own) mediated the association between ACEs and symptoms in the FMS group only. Externalised self-perception (judging oneself according to perceived external standards) was negatively associated with symptoms but presented no mediating effects. Results present preliminary new information to explain the association between ACEs and FMS. Recognition of the factors which underlie symptomology is important in understanding the condition and supporting patients.
The use of an intrauterine balloon in preventing adhesion recurrence after hysteroscopic adhesiolysis: a feasibility study

Abstract We aimed to evaluate the feasibility of a heart-shaped intrauterine balloon as antiadhesion method immediately after hysteroscopic adhesiolysis in terms of surgeon’s and patient’s experience. This feasibility study was performed at the Ghent University Hospital (Belgium) from 2018 to 2020. A heart-shaped intrauterine balloon was inserted in 10 women immediately after hysteroscopic adhesiolysis and left in place for 7 days under antibiotic prophylaxis. Insertion and removal of the balloon was easy in 7 women out of 10 (5-point Likert scale), and successful in all cases. The median pain score during balloon wearing on a visual analogue scale (VAS) was 1.7 (IQR 1.0–4.2). Seven out of 10 women were satisfied (5-point Likert scale). Eight out of 10 women would probably or certainly recommend the procedure to a friend (5-point Likert scale) and would use the balloon again. The heart-shaped intrauterine balloon as antiadhesion method is feasible in terms of surgeon’s and patient’s experience. Designing a proper Randomised Controlled Trial (RCT) is worth the effort. Clinical trial registration: https://clinicaltrials.gov (NCT03446755). Initial release on 27th February 2018. IMPACT STATEMENT What is already known on this subject? Intrauterine adhesion (IUA) reformation is high and different methods to prevent this subsequent to an operative hysteroscopy have been assessed. The use of antiadhesion gel, acting as a mechanical barrier, may decrease the occurrence of IUAs compared to no treatment or placebo. A heart-shaped intrauterine balloon is another example of a mechanical barrier. A small number of studies, of varying quality and with heterogeneous results, have been performed. A proper RCT, comparing the intrauterine balloon to no treatment or placebo, is needed. What the results of this study add? The heart-shaped intrauterine balloon as antiadhesion method is feasible in terms of surgeon’s and patient’s experience. What the implications are of these findings for clinical practice and/or further research? Designing a proper RCT is worth the effort.
KOLMOGOROV-SMIRNOV- AND CRAMÈR-VON MISES TYPE TWO-SAMPLE TESTS WITH VARIOUS WEIGHT FUNCTIONS

For the general two-sample problem we introduce modifications of the Kolmogorov-Smirnov- and Cramèr-von Mises test by using various weight functions. We compare these modified tests with the classical Kolmogorov-Smirnov- and Cramèr-von Mises tests as well as with the Lepage test for location and scale alternatives including the same shape and different shapes of the distributions of the X- and Y-variables. The power comparison of the tests is carried out via Monte Carlo simulation assuming short-, medium- and long-tailed distributions as well as distributions skewed to the right. It turns out there is mostly a considerable gain of power by applying these modified versions of the Kolmogorov-Smirnov- and Cràmer-von Mises tests. On the basis of the power results an adaptive test is proposed which takes into account the given data set.
