The Psychological Impact and Associated Factors of COVID-19 on the General Public in Hunan, China

Purpose This study aimed to assess the psychological impact of the COVID-19 pandemic among the general public in Hunan Province, China, which could help develop psychological interventions and mental health programs. Participants and Methods This online cross-sectional study recruited 571 participants through snowball sampling between February 2 and February 5, 2020. Data were collected through a general information questionnaire, the Public Emergency Psychological State Questionnaire, the Simple Coping Style Questionnaire, and the Public Disease Awareness on COVID-19 Scale. Results The total mean score of the public emergency psychological state of the sample was 0.27 (0.31) points, with only 5.78% of participants (n = 33) developing psychological distress. Avoidant coping style and disease awareness were weakly positively correlated (rs = 0.257, p < 0.01) and weakly negatively correlated (rs = −0.124, p <0.01) with psychological responses, respectively. There were significant psychological differences among the following variables: occupation, symptoms of fever or fatigue, discernment of the authenticity of COVID-19 information, and level of concern regarding COVID-19 (p < 0.05). Conclusion The COVID-19 pandemic appears to have had a minor psychological impact on the general population in Hunan Province. However, psychological health promotion in the general public is still required, especially for employees (such as company employees, migrant workers, and businessmen), individuals with COVID-19-like symptoms, limited discernment competence and unconcerned attitudes. Implications The initiatives for improving psychological health among the general public could focus on delivering COVID-19 knowledge and alleviating avoidant coping styles. Our findings could provide important insight for the development of psychological support strategies in China, as well as in other places affected by the epidemic.
Negligible hormonal response following dehorning in free-ranging white rhinoceros (Ceratotherium simum)

Private reserves and national parks in southern Africa are increasingly dehorning their rhinos. This study monitored changes in the faecal hormone metabolites of white rhinos subject to this procedure. The findings indicate that dehorning had a negligible impact on hormone metabolite profiles and that dehorning did not cause a long-term physiological stress response in rhinos.
The structural biology center at the APS: an integrated user facility for macromolecular crystallography

The Structural Biology Center (SBC) has developed and operates a sector (undulator and bending magnet) of the APS as a user facility for macromolecular crystallography. Crystallographically determined structures of proteins, nucleic acids and their complexes with proteins, viruses, and complexes between macromolecules and small ligands have become of central importance in molecular and cellular biology. Major design goals were to make the extremely high brilliance of the APS available for brilliance limited studies, and to achieve a high throughput of less demanding studies, as well as optimization for MAS-phasing. Crystal samples will include extremely small crystals, crystals with large unit cells (viruses, ribosomes, etc.) and ensembles of closely similar crystal structures for drug design, protein engineering, etc. Data are recorded on a 3000×3000 pixel CCD-area detector (optionally on image plates). The x-ray optics of both beamlines has been designed to produce a highly demagnified image of the sour.
Dynamic analysis of serum Ca-125 levels during neoadjuvant chemotherapy in patients with advanced epithelial ovarian cancer: a retrospective study

Ovarian cancer is the seventh most common cancer worldwide. The disease remains relatively asymptomatic in the early stages and hence majorities are diagnosed at a later stage. Major site of metastasis is peritoneal cavity. The 5-year survival of advanced stage carcinoma ovaray is less than 30% only. The main stay treatment of advanced ovarian carcinoma is primary debulking surgery and followed by adjuvant chemotherapy. With respect to factors like performance status of patient, general condition and operability there is an alternative approach of platinum-based chemotherapy followed by interval debulking surgery (IDS) also exist. CA-125 is the serum maker used for the diagnosis as well as post-treatment follow-up of ovarian cancer patients. There is a new system of response assessment criteria is widely accepted over the response assessment of advanced ovarian cancer patients who undergo neoadjuvant chemotherapy (response evaluation criteria in solid tumors (RECIST) version 1.1).
GENDER ROLES AND DIMENSIONS OF FAMILY FUNCTIONING AS PREDICTORS OF SUBJECTIVE WELL-BEING IN MEN AND WOMEN

Subjective well-being (a positive attitude towards life and positive affectivity) as an important indicator of mental health attracts a lot of attention in the field of positive psychology. For the sake of improving mental health, research was mainly focused on identifying factors related to it. So far, findings indicate there is a need for a better understanding of the characteristics of both individual and family environments. To that end, the aim of this study was to examine gender differences and what contributes to the subjective well-being of men and women. The study examined gender roles, masculinity and femininity, aspects of family functioning, education and the number of children. The sample included 1417 respondents who are married or in a relationship (586 men, 802 women), and the following questionnaires were used: a shorter versions of the Subjective Well-Being Scale, the Masculinity and Femininity Scale and the Family Functioning Scale, as part of the larger PORPOS2 battery. The results showed that masculinity and femininity, and adequate communication in the family are important indicators of a positive attitude towards the life of both genders. Masculinity and satisfaction with communication play a significant role when it comes to the positive affectivity in both men and women. The level of cohesiveness also plays an important role in the subjective well-being of men, and the number of children is a negative predictor of both dimensions of subjective well-being in women. Based on these results, we can conclude that a better understanding of the subjective well-being of men and women requires a more focused approach, which can be important in both research and psychotherapeutic work.
Demand for Imported Staple Food Commodities in the Kingdom of Saudi Arabia

This research empirically estimated the demand for imported staple food commodities in the Kingdom of Saudi Arabia using dated data of 38 years (1980 to 2017) sourced from Food and Agriculture Organization and United Nations Conference on Trade and Development databases. The collected data covered the consumer price index; import quantities and expenditures of fifteen staple food commodities. The collected data were analysed using descriptive statistics and linear expenditure system almost ideal demand system (LES/AIDS) model. The empirical evidence showed the diversification on food spending to be very low as one commodity (barley) had a dominant influence on the consumers’ budget expenditure. Furthermore, it was observed that the dietary diversity of consumers is low. Income effect had strong influence than the substitution effect in determining the demand for the selected imported commodities. It also showed that as consumers’ income increase and consumers’ diversify their diets, the consumption of non-staple foods rather than the staple foods would increase. Therefore, the study recommends that people should be encouraged to engage in optimal dietary diversification in order to enhance their diet nutritional quality and health status. However, since almost all of the commodities are important given that they fulfilled the needs of the people, especially the poor who face tight budgetary constraints. Thus, it becomes imperative for the policymakers to enhance their home-grown economy so as enhance the economy, foreign exchange reserve and protect the health status of the country population.
Diversity in Education and Organization: From Political Aims to Practice in the Norwegian Police Service

Police agencies implement a variety of strategies for recruiting, promoting and retaining police officers with diverse backgrounds. Changes have however been difficult to attain. We expand research on representative bureaucracy by investigating diversity perspectives in a case study of the Norwegian Police Service (NPS). Using mixed-methods we investigate the diversity perspectives of ethnic minority and majority students and employees in the NPS, focusing on the interplay between educational and work experiences, recruitment practices and diversity policies. We found that ethnic minorities were still underrepresented, and their cultural competence was not fully recognized by other students, teachers, colleagues and leaders. Interview and field-work findings were corroborated by surveys among NPS employees documenting that competence development was perceived as the least emphasized justification for diversity management. Despite focusing on a single case, the NPS, we argue that the processes we describe may be operating also in other multicultural societies.
Impact of upper mantle convection on lithosphere hyperextension and subsequent horizontally forced subduction initiation

Abstract. Many plate tectonic processes, such as subduction initiation, are embedded in long-term ( >100 Myr) geodynamic cycles often involving subsequent phases of extension, cooling without plate deformation and convergence. However, the impact of upper mantle convection on lithosphere dynamics during such long-term cycles is still poorly understood. We have designed two-dimensional upper-mantle-scale (down to a depth of 660 km) thermo-mechanical numerical models of coupled lithosphere–mantle deformation. We consider visco–elasto–plastic deformation including a combination of diffusion, dislocation and Peierls creep law mechanisms. Mantle densities are calculated from petrological phase diagrams (Perple_X) for a Hawaiian pyrolite. Our models exhibit realistic Rayleigh numbers between 106 and 107 , and the model temperature, density and viscosity structures agree with geological and geophysical data and observations. We tested the impact of the viscosity structure in the asthenosphere on upper mantle convection and lithosphere dynamics. We also compare models in which mantle convection is explicitly modelled with models in which convection is parameterized by Nusselt number scaling of the mantle thermal conductivity. Further, we quantified the plate driving forces necessary for subduction initiation in 2D thermo-mechanical models of coupled lithosphere–mantle deformation. Our model generates a 120 Myr long geodynamic cycle of subsequent extension (30 Myr), cooling (70 Myr) and convergence (20 Myr) coupled to upper mantle convection in a single and continuous simulation. Fundamental features such as the formation of hyperextended margins, upper mantle convective flow and subduction initiation are captured by the simulations presented here. Compared to a strong asthenosphere, a weak asthenosphere leads to the following differences: smaller value of plate driving forces necessary for subduction initiation (15 TN m −1 instead of 22 TN m −1 ) and locally larger suction forces. The latter assists in establishing single-slab subduction rather than double-slab subduction. Subduction initiation is horizontally forced, occurs at the transition from the exhumed mantle to the hyperextended passive margin and is caused by thermal softening. Spontaneous subduction initiation due to negative buoyancy of the 400 km wide, cooled, exhumed mantle is not observed after 100 Myr in model history. Our models indicate that long-term lithosphere dynamics can be strongly impacted by sub-lithosphere dynamics. The first-order processes in the simulated geodynamic cycle are applicable to orogenies that resulted from the opening and closure of embryonic oceans bounded by magma-poor hyperextended rifted margins, which might have been the case for the Alpine orogeny.
Parameterization of the Collection Efficiency of a Cylindrical Catching-Type Rain Gauge Based on Rainfall Intensity

Despite the numerous contributions available in the literature about the wind-induced bias of rainfall intensity measurements, adjustments based on collection efficiency curves are rarely applied operationally to rain records obtained from catching-type rain gauges. The many influencing variables involved and the variability of the results of field experiments do not facilitate the widespread application of adjustment algorithms. In this paper, a Lagrangian particle tracking model is applied to the results of computational fluid dynamic simulations of the airflow field surrounding a rain gauge to derive a simple formulation of the collection efficiency curves as a function of wind speed. A new parameterization of the influence of rainfall intensity is proposed. The methodology was applied to a cylindrical gauge, which has the typical outer shape of tipping-bucket rain gauges, as a representative specimen of most operational measurement instruments. The wind velocity is the only ancillary variable required to calculate the adjustment, together with the measured rainfall intensity. Since wind is commonly measured by operational weather stations, its use adds no relevant burden to the cost of meteo-hydrological networks.
Light-Load Efficiency Optimization for an LCC-Parallel Compensated Inductive Power Transfer Battery Charger

Wireless power transfer (WPT) techniques have gained wide acceptance across a range of battery charging applications such as cell phones, cardiac pacemakers, and electric vehicles. In a wireless battery charging system, a constant current/constant voltage (CC/CV) charging strategy, regardless of the variation of the battery load which may roughly range from a few ohms to several hundred ohms, is typically adopted to ensure the safety, durability, and performance of the battery. However, system efficiency drops significantly as the load increases in CV mode, especially at very light-load conditions. This paper proposes an efficiency optimization method for an LCC-parallel compensated inductive power transfer (IPT) battery charging system without the help of any additional power converter and control method. The equivalent circuit and resonant conditions of the LCC-parallel compensation topology are firstly analyzed to achieve the load-independent CV output at a zero phase angle (ZPA) operating frequency. Over the full range of CV charging mode, the efficiency of the LCC-parallel resonant tank circuit is analyzed and optimized. An IPT battery charger prototype with 48 V charging voltage and 1 A charging current is implemented. A measured DC–DC transfer efficiency of greater than 90.48% is achieved during the whole CV charging profile.

The wide application of information technology and network technology in automobiles has made great changes in the Human-computer interaction. This paper studies the influence of Human-computer interaction modes on driving safety, comfort and efficiency based on physical interaction, touch screen control interaction, augmented reality, speech interaction and somatosensory interaction. The future Human-com-puter interaction modes such as multi-channel Human-computer interaction mode and Human-computer interaction mode based on biometrics and perception techno-logy are also discussed. At last, the method of automobile Human-computer interaction design based on the existing technology is proposed, which has certain guiding significance for the current automobile Human-computer interaction interface design.
Identification of crucial genes mediating abdominal aortic aneurysm pathogenesis based on gene expression profiling of perivascular adipose tissue by WGCNA

Background With a mortality rate of 65–85%, a ruptured abdominal aortic aneurysm (AAA) can have catastrophic consequences for patients. However, few effective pharmaceutical treatments are available to treat this condition. Therefore, elucidating the pathogenesis of AAA and finding the potential molecular targets for medical therapies are vital lines of research. Methods An mRNA microarray dataset of perivascular adipose tissue (PVAT) in AAA patients was downloaded and differentially expressed gene (DEG) screening was performed. Weighted gene co-expression networks for dilated and non-dilated PVAT samples were constructed via weighted correlation network analysis (WGCNA) and used to detect gene modules. Functional annotation analysis was performed for the DEGs and gene modules. We identified the hub genes of the modules and created a DEG co-expression network. We then mined crucial genes based on this network using Molecular Complex Detection (MCODE) in Cytoscape. Crucial genes with top-6 degree in the crucial gene cluster were visualized, and their potential clinical significance was determined. Results Of the 173 DEGs screened, 99 were upregulated and 74 were downregulated. Co-expression networks were built and we detected 6 and 5 modules for dilated and non-dilated PVAT samples, respectively. The turquoise and black modules for dilated PVAT samples were related to inflammation and immune response. MAP4K1 and PROK2 were the hub genes of these 2 modules, respectively. Then a DEG co-expression network with 112 nodes and 953 edges was created. PLAU was the crucial gene with the highest connectivity and showed potential clinical significance. Conclusions Using WGCNA, gene modules were detected and hub genes and crucial genes were identified. These crucial genes might be potential targets for pharmaceutic therapies and have potential clinical significance. Future in vitro and in vivo experiments are required to more comprehensively explore the biological mechanisms by which these genes affect AAA pathogenesis

Use of Smartphones in Class: Examining the Relationship Between M-Learning Readiness, Cyberloafing, Nomophobia and Addiction Variables

The aim of this study is to examine the relationship between pre-service preschool teachers' mobile-learning (m-learning) readiness, cyberloafing, nomophobiaand smartphone addiction variables. The study was carried out using 306 pre-service preschool teachers undergoing education at state-run universities in two different cities in Turkey. The most critical conclusion of the study is that the smartphones used by pre-service preschool teachers both for m-learning and for cyberloafing in class have an impact on nomophobia and smartphone addiction. In the study, the effects of smartphone usage on both the learning environment and the individual were discussed in accordance with the proposed model. Suggestions for the use of smartphones were made in line with the study's conclusions.
Spray Synthesis of Photonic Crystal Based Automotive Coatings with Bright and Angular‐Dependent Structural Colors

It is a challenge to prepare photonic crystal (PC) automotive coatings via spraying colloidal solutions because the fast fabrication tends to produce amorphous photonic crystals with faint colors. Here, a two‐step spraying process followed by thermal curing is developed to prepare waterproof PC coatings with bright, uniform, and angular‐dependent structural colors. The solvents in PC paint are studied to achieve a quick formation of liquid PC intermediate, which transformed into a highly crystalline PC coating. Thanks to the narrow and intense reflections, the as‐made coatings present colors with high saturation, including the red/yellow/green/blue colors achieved by tuning the particle size, and many spectral/non‐spectral colors via the mixing of base colors. Meanwhile, patterned or fully covered PC coatings with good chemical and mechanical stability can be prepared on different substrates, where the shiny colors changing with the viewing angles or the surface curvatures offer a new choice for personalized automotive coatings.
Predicting Individuals’ Experienced Fear From Multimodal Physiological Responses to a Fear-Inducing Stimulus

Emotions are experienced differently by individuals, and thus, it is important to account for individuals’ experienced emotions to understand their physiological responses to emotional stimuli. The present study investigated the physiological responses to a fear-inducing stimulus and examined whether these responses can predict experienced fear. A total of 230 participants were presented with neutral and fear-inducing film clips, after which they self-rated their experienced emotions. Physiological measures (skin conductance level and response: SCL, SCR, heart rate: HR, pulse transit time: PTT, fingertip temperature: FT, and respiratory rate: RR) were recorded during the stimuli presentation. We examined the correlations between the physiological measures and the participants’ experienced emotional intensity, and performed a multiple linear regression to predict fear intensity based on the physiological responses. Of the participants, 92.5% experienced the fear emotion, and the average intensity was 5.95 on a 7-point Likert scale. Compared to the neutral condition, the SCL, SCR, HR, and RR increased significantly during the fear-inducing stimulus presentation whereas FT and PTT decreased significantly. Fear intensity correlated positively with SCR and HR and negatively with SCL, FT, PTT, and RR. The multiple linear regression demonstrated that fear intensity was predicted by a combination of SCL, SCR, HR, FT, and RR. Our findings indicate that the physiological responses to experiencing fear are associated with cholinergic, sympathetic, and α-adrenergic vascular activation as well as myocardial β-sympathetic excitation, and support the use of multimodal physiological signals for quantifying emotions.

"Supermarket Column Chromatography of Leaf Pigments" Revisited: Simple and Ecofriendly Separation of Plant Carotenoids, Chlorophylls, and Flavonoids from Green and Red Leaves.

A simple and ecofriendly procedure was developed in order to prepare extracts from red and green leaves. This procedure enables the separation of yellow, green, and red band pigments and optimizes the previously reported baking soda “supermarket column”. The same extract also led to a novel and colorful potato starch column, which can efficiently separate β-carotene, xanthophylls, chlorophylls a and b, and flavonoids. Thus, two simple and attractive “supermarket columns” are presented that may be implemented either in university or high-school practical classes. The challenges associated with separation of these pigments, which have diverse physical and chemical properties, will improve the expected learning outcomes of these activities.
