    Aims: The authors sought to explore the psychological distress of teachers during COVID-19 pandemic and their preference for psychological intervention. The overarching goal was to gain insight on how to build an effective psychological support system for teachers during and after the pandemic. Methods: The mental health condition of teachers (N = 18,521) was assessed online by using a questionnaire consisting of standard instruments PHQ-15, GAD-7, PHQ-2, PC-PTSD, and additional ...

    In the present paper, studies of the effects of metal ion (Y+, Ag+) implantation on the tribology and moisture resistance of r.f.-sputtered MoS2 films are reported. The scratch test indicates an improved film-substrate adherence. This is mainly attributed to the mixing interface which was caused by metal ion implantation. The tribological test results indicate that metal ion implantation improves the wear life of the sputtered MoS2 films in an atmosphere of 60–70% relative humidity (RH) ...

    The spectral characteristics of variable selection are particularly important for wetland vegetation mapping. In the present study, we combined soil salt and water content with spectral data collected in the Ebinur Lake Wetland National Nature Reserve (ELWNNR) in Western China to understand the effects of soil salt and water content on plant spectra. The results showed the following: (1) the distribution of plants reflect the macroscopic response characteristics of plants on water and ...

    Accurate estimates of grass biomass can provide valuable information about the productivity and functioning of rangelands and grassland ecological resource utilizing more reasonable. In order to improve the biomass quantitative analysis with hyperspectral remote sensing data, a field experiment was carried out in Gannan rangelands, Gansu province. To achieve this objective, fresh grass aboveground biomass and hyperspectral canopy reflectance were collected at four types pasture in august ...

    The binary europium complex EuL3 (L=4-tert-butylbenzoate) and ternary europium complexes EuL3TTA0.1 (TTA=2- thenoyltrifluoroacetone), EuL3DBM0.5 (DBM=dibenzoylmethane) and EuL3phen0.5 (phen=1, 10-phenanthroline) were synthesized. The poly(methyl methacrylate) (PMMA) or copolymer of methyl methacrylate (MMA) with acrylic acid (AA) composites doped with europium complexes were prepared by radical in-situ polymerization. The influences of the europium complexes, ligands, ...

    Software maintenance is assuming ever more a crucial role in the lifecycle of software due to the increase of software requirements and the high variability of software environment. Common approaches of studying software maintenance are to consider them as a static by-product of software operation and only the maintenance cost is covered. In this paper, software maintenance policies are studied with the consideration of software reliability and risk. An optimization model is defined to ...

    The smooth surface of the metallic nanostructure is essential for the propagation of surface plasmon polaritons. In this paper, we present a novel method to fabricate the metallic nanopatterns with ultra-smooth surface on various substrates. By using a silica film as the sacrificial layer, we show that the prefabricated metallic nanopatterns produced by electron beam lithography and film deposition can be hydrolyzed and transferred onto a designated substrate. The ultra-smooth surface ...

    Region of Interest (ROI) is the key basis of visual features extraction in lip-reading process. In this paper, we discussed the ROI processing method and explored its impact on recognition accuracy with the comparison of four kinds of processed ROIs obtained by using four basic image processing methods: gray-scale normalization, difference enhancement, edge enhancement and image segmentation. Then recognition tasks for speaker-independent lip-reading were carried out by the aid of ...

    The aim of this study was to investigate the attitudes of Chinese community members and psychiatrists towards forensic psychiatric assessments. A questionnaire designed to record attitudes toward the current forensic psychiatric assessment procedures and the disposal of mentally ill offenders was developed and distributed via a mobile App. A total of 134 community members and 132 psychiatrists voluntarily completed the questionnaire. Most of responders agreed that the department of ...

    the model, predicting fatigue life of ductile iron, based on SVM (Support Vector Machine, SVM) has been established. For it is easy to fall into local optimum during parameter optimization of SVM, DE (Differential Evolution algorithm, DE) algorithm was adopted to optimize to improve prediction precision. Fatigue life of ductile iron is predicted combining with concrete examples, and simulation experiment to optimize SVM is conducted adopting GA (Genetic Algorithm), ACO (Ant Colony ...

    In this paper, based on 16-day 250m MODIS product suits, using residual trend method, the effects of Restoring Grazing to Grassland Project in Maqu grassland was evaluated. Firstly, some regression models between NDVI in different stage and synchronous meteorological data were constructed. Then using above models we can predict NDVI value without the project and analyze the residual trend of actual NDVI and simulative NDVI from 2000 to 2006. Finally, the effect of restoring grazing to ...

    This paper describes the investigation of the electrochemical behaviour of cadmium ion transfer across the water/nitrobenzene (w/nb) interface facilitated by 2.2'-bipyridine using semi-differential cyclic voltammetry. The transfer mechanism has been studied. Expressions for the peak current, peak potential and half-wave width under different conditions are given: (1) is related to equals 3.52 RT/nF and ep is directly proportional to (2) is not only dependent on cMw* but also on cLnb*. ...
