Epitaxial indium antimonide for multiband photodetection from IR to millimeter/terahertz wave
Authors: Tong Jinchao , Luo Heng , Suo Fei , Zhang Tianning , Zhang Dawei , Zhang Dao Hua 
Published: March 2022

Conventional photodetection converts light into electrical signals only in a single electromagnetic waveband. Multiband detection technology is highly desirable because it can handle multispectral information discrimination, identification, and processing. Current epitaxial solid-state multiband detection technologies are mainly within the IR wave range. Here, we report epitaxial indium antimonide on gallium arsenide for IR and millimeter/terahertz wave multiband photodetection. The photoresponse originates from interband transition in optoelectrical semiconductors for IR wave, and surface plasmon polaritons induced nonequilibrium electrons for a millimeter/terahertz wave. The detector shows a strong response for an IR wave with a cutoff wavelength of 6.85 μm and a blackbody detectivity of

at 0.270 THz (1.1 mm) at room temperature. The detection performance is an order of magnitude better while decreasing the temperature to 170 K, the thermoelectric cooling level. Such detectors, capable of large scale and low cost, are promising for advanced uncooled multiband detection and imaging systems.

Background
The increasing insecticide resistance of Aedes albopictus puts many countries in Asia and Africa, including China, at great risk of a mosquito-borne virus epidemic. To date, a growing number of researches have focused on the relationship between intestinal symbiotic bacteria and their hosts’ resistance to insecticides. This provides a novel aspect to the study of resistant mechanisms.

Methods/Findings
This study reveals significant composition and dynamic changes in the intestinal symbiotic bacteria of Ae. albopictus between the resistant and susceptible strains based on full-length sequencing technology. The relative abundance of Serratia oryzae was significantly higher in the resistance strain than in the susceptible strains; also, the relative abundance of S. oryzae was significantly higher in deltamethrin-induced Ae. albopictus than in their counterpart. These suggested that S. oryzae may be involved in the development of insecticide resistance in Ae. albopictus. To explore the insecticide resistance mechanism, adult mosquitoes were fed with GFP-tagged S. oryzae, which resulted in stable bacterial enrichment in the mosquito gut without affecting the normal physiology, longevity, oviposition, and hatching rates of the host. The resistance measurements were made based on bioassays as per the WHO guidelines. The results showed that the survival rate of S. oryzae-enriched Ae. albopictus was significantly higher than the untreated mosquitoes, indicating the enhanced resistance of S. oryzae-enriched Ae. albopictus. Also, the activities of three metabolic detoxification enzymes in S. oryzae-enriched mosquitoes were increased to varying degrees. Meanwhile, the activity of extracellular enzymes released by S. oryzae was measured, but only carboxylesterase activity was detected. HPLC and UHPLC were respectively used to measure deltamethrin residue concentration and metabolite qualitative analysis, showing that the deltamethrin degradation efficiency of S. oryzae was positively correlated with time and bacterial amount. Deltamethrin was broken down into 1-Oleoyl-2-hydroxy-sn-glycero-3-PE and 2’,2’-Dibromo-2’-deoxyguanosine. Transcriptome analysis revealed that 9 cytochrome P450s, 8 GSTs and 7 CarEs genes were significantly upregulated.

Conclusions
S. oryzae can be accumulated into adult Ae. albopictus by artificial feeding, which enhances deltamethrin resistance by inducing the metabolic detoxification genes and autocrine metabolic enzymes. S. oryzae is vertically transmitted in Ae. albopictus population. Importantly, S. oryzae can degrade deltamethrin in vitro, and use deltamethrin as the sole carbon source for their growths. Therefore, in the future, S. oryzae may also be commercially used to break down the residual insecticides in the farmland and lakes to protect the environment.

Published: March 2022

Purpose
During the COVID pandemic, many hospitals had to mobilize reinforcement healthcare workers, especially in intensive care (ICUs). We investigated the perceptions and experiences of reinforcement workers deployed to ICUs, and the impact of deployment on their personal and professional lives.

Methods
For this qualitative study, a random sample of 30 reinforcement workers was drawn from 4 centres participating in the larger PsyCOVID-ICU study. Individual semi-structured interviews were held, recorded, transcribed and analyzed by thematic analysis.

Results
Thirty interviews were performed from April to May 2021 (22 nurses, 2 anesthesiology nurses, 6 nurses’ aides). Average age was 36.8±9.5 years; 7 participants had no ICU experience. Four major themes emerged, namely: (1) Difficulties with integration, especially for those with no ICU experience; (2) lack of training; (3) difficulties with management, notably a feeling of insufficient communication; (4) Mental distress relating to the unusual work and fear of contaminating their entourage.

Conclusion
Healthcare workers deployed as reinforcements to ICUs at the height of the pandemic had a unique experience of the crisis, and identified important gaps in organisation and preparation. They also suffered from a marked lack of training, given the stakes in the management of critically ill patients in the ICU.

Published: March 2022

Background COVID-19 has spread around the world. Although symptoms in children are often mild, children remain at risk of developing severe or critical forms of COVID-19, especially those with underlying or comorbid medical conditions.
Objective To evaluate the association between comorbidities and severity of COVID-19 in pediatric patients.
Methods A systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. We used PubMed and Google Scholar to locate observational studies that involved children with RT-PCR-confirmed COVID-19 with comorbidities and compared them with controls without comorbidities. Studies must also involve children with severe COVID-19 and provide the risk of severe COVID-19 in children with and without comorbidities as outcome. We performed a meta-analysis to estimate the pooled odds ratio (OR) of severe COVID-19 in children with vs. without comorbidities.
Results We included 41 observational studies with a total of 285,828 pediatric COVID-19 patients, comprising 9,754 patients with comorbidities and 276,074 controls. The comorbidities indentified included obesity, congenital malformations, neurological disease, and genetic syndromes. Children with comorbidities had a significantly higher risk of developing severe COVID-19 compared to those without (pooled OR 4.07; 95%CI 2.31 to 7.19; P<0.00001).
Conclusion The presence of comorbidities increases the risk of severe COVID-19 in children.

Published: March 2022

Perennialism is a learning theory that maintains the purity of traditional teachings, and rejects modernization that rejects human life. Gadgets are products resulting from the modernization that is happening at this time. In fact, Gadgets were created to make it easier for humans to communicate between each other, but the fact is that technological advances are still being misused by some groups of people, so that they can have quite a fatal impact on these users. This research method is descriptive qualitative. This type of research is literature or literature research. Literature research is a type of research that collects data sources based on reference materials such as books, journals, articles and other scientific works. The results of this study indicate that gadgets are not a basic requirement for elementary school children, and intense supervision from parents is also needed on this problem.

Authors: Kartal F. , Kişioğlu Y. 
Published: March 2022

Abstract
This study addresses the determination of the fatigue life and its failure locations of the vehicle cylindrical LPG fuel tanks using both experimental and finite element analysis (FEA) methods. The experimental investigations performed as an accelerated fatigue tests are carried out using a hydraulics test unit in which the cylinders are internally pressurized by hydraulic oil. The LPG cylinders are subjected to repeated cyclic pressure varying from zero to service pressure of the tank. The FEA modeling of these tanks are developed in three dimensional (3D) using non-uniform geometrical parameters and nonlinear material properties. These models are also subjected to zero-based high cycle fatigue pressure load considering the stress life approach. The FEA modeling process is also simulated in non-homogeneous material conditions. Therefore, the fatigue life performance and failure location of the cylindrical LPG fuel tanks are predicted and compared to the experimental results.
Kurz und lang, Spreu und Weizen, Arsch und Mond – Volcnant und Walther
Authors: Herweg Mathias 
Published: March 2022

Abstract
Walther’s von der Vogelweide aggressive stanza against an, otherwise unknown, Volcnant or Wîcman (L 17,25) opens up the lasting tradition of artistic polemics and ›peer-bashing‹ in German Sangspruchdichtung. Henceforth, the agonal rivalry between artists becomes the favourite field of a particularly harsh polemic.
The article examines the pioneer’s text with regard to the split (or doubled) role of the singer who adopts two grammatical persons (which seems also to be crucial for Walther’s disputed authorship), to the metaphorical structure and to the discursive as well as generic references of the text. The singer in the text is boasting himself by constructing and simultaneously destructing an aggressively ridiculed counterpart. This, however, is not to be understood in biographical terms, but in genuinely poetological and professional ones: Walther claims his unsurpassed competence (meisterschaft) in all registers and varieties of an art that ranges far from well-tempered courtesy up to the most exquisite scolding. Scharpfer sanc is not an antithesis but a subset of courtly art and poetry.
The Health and Retirement Study: Contextual Data Augmentation
Authors: Dick Christopher 
Published: March 2022

Abstract
The Health and Retirement Study is an amazing resource for those studying aging in the United States, and a fantastic model for other countries who have created similar longitudinal studies. The raw amount of information, from data on income, wealth, and use of health services to employment, retirement, and family connections on to the collection of clinical biomarkers can be both empowering and overwhelming to a researcher. Luckily through the process of engagement with the research community and constant improvement, these reams of data are not only consistently growing in a thoughtful and focused direction, they are also explained and summarized to increase the ease of use for all. One of the very useful areas of the HRS is the Contextual Data File (CDF), which is the focus of this review. The CDF provides access to easy-to-use helpful community-level data in a secure environment that has allowed researchers to answer questions that would have otherwise been difficult or impossible to tackle. The current CDF includes data in six categories (University of Michigan Institute for Social Research. 2017. HRS Data Book: The Health and Retirement Study: Aging in the 21st Century, Challenges and Opportunities for Americans. Ann Arbor: University of Michigan. Also available at https://hrs.isr.umich.edu/about/data-book, 17): 1. Socio-economic Status and Demographic Structure 2. Psychosocial Stressors 3. Health Care 4. Physical Hazards 5. Amenities 6. Land Use and the Built Environment. Each of these areas have allowed researchers to answer interesting questions such as what is the impact of air pollution on cognition in older adults (Ailshire, J., and K. M. Walsemann. 2021. “Education Differences in the Adverse Impact of PM 2.5 on Incident Cognitive Impairment Among U.S. Older Adults.” Journal of Alzheimer’s Disease 79 (2): 615–25), the impact of neighborhood characteristics on obesity in older adults (Grafova, I. B., V. A. Freedman, R. Kumar, and J. Rogowski. 2008. “Neighborhoods and Obesity in Later Life.” American Journal of Public Health 98: 2065–71), or even what do we gain from introducing contextual data to a survey analysis (Wilkinson, L. R., K. F. Ferraro, and B. R. Kemp. 2017. “Contextualization of Survey Data: What Do We Gain and Does it Matter?” Research in Human Development 14 (3): 234–52)? My review focuses on the potential to expand contextual data in a few of these areas. From new data sets developed and released by the U.S. Census Bureau, to improved measurements of climate and environmental risk, there are numerous new data sources that would be a boon to the research community if they were joined together with the HRS. The following section begins by breaking down the opportunity provided by community or place-based data before moving on to specific recommendations for new data that could be included in the HRS contextual data file.
Co-immobilization of glucose oxidase and catalase in porous magnetic chitosan microspheres for production of sodium gluconate
Authors: Liu Youcai , Zou Pengpeng , Huang Juan , Cai Jun 
Published: March 2022

Abstract
In the process of immobilizing the enzyme, the overflow of enzyme and the decrease of enzyme activity are very serious. In order to improve the stable binding between enzyme and carrier, a kind of porous magnetic chitosan microsphere with appropriate pore size was successfully prepared by adjusting the size of pore-forming agent in this paper. The rough porous structure is favorable for the adsorption of enzyme and the catalytic action of enzyme on substrate. The results showed that when the pore size of the microspheres was at 790.15 ± 250.91 nm, the protein loading and enzyme activity of GOD could be increased effectively, which could reach 58.28 ± 2.64 mg/g and 16.93 ± 0.14 U, respectively. The co-immobilization of CAT and GOD eliminated the harmful by-product H2O2 in time and effectively solved the problem of continuous deactivation of GOD in the reaction process. When the mass ratio of PMCSM/GOD/CAT was 100/6.02/10.96 (mg/mg/mg), the relative enzyme activity of GOD reached the highest (133.32 ± 0.68%). The thermal stability and pH stability of the enzyme were greatly improved after co-immobilization. The relative enzyme activity of PMCSM@GOD@CAT was 57.27 ± 3.04% at 60 °C, while that of free GOD was only 28.76 ± 4.10%. The relative enzyme activity of PMCSM@GOD@CAT was above 63% at pH 5–10, while the relative enzyme activity of free GOD was only 4.98 ± 0.72% at pH 10. The yield of sodium gluconate from 50 mL 250 mg/mL glucose catalyzed by PMCSM@GOD@CAT loading 60.2 mg GOD was 96.19 ± 0.79% at pH 6.0 and 30 °C, and the reaction lasted 6 h. The relative enzyme activity of PMCSM@GOD@CAT remained 69.77 ± 0.78% after repeated use for 10 times. After 30 days of storage, PMCSM@GOD@CAT maintained its initial activity of 76.52 ± 1.41%. The immobilized process studied in this paper provides a theoretical basis for the production of sodium gluconate by double enzyme directly catalyzing and lays a certain foundation for the application of immobilized enzyme in the future chemical industry and food industry.
Estimation of the viscosity for Ag–In and In–Sb liquid alloys using different models
Authors: Živković Dragana 
Published: March 2022

Abstract
The results of the estimation of the viscosity for Ag – In and In–Sb liquid alloys are presented in this paper. Different theoretical models for viscosity determination, according to the Moelwyn–Hughes, Iida –Ueda –Morita, Kozlov– Romanov– Petrov, Hirai, Seetharaman – DuSichen and Kaptay, have been applied in the process of viscosity calculation at different temperatures – for the Ag– In alloys in the range 1073 – 1273 K and for the In–Sb alloys in the range 873 – 1073 K. The results for both systems, obtained using different models, were compared mutually and with available literature experimental data. The models, mostly capable to predict appropriate viscosity data for investigated binary systems, were defined.

Published: March 2022

Abstract
“Order – order” kinetics was studied by means of “in situ” and quasi-residual (REST) resistometry in bulk and thin films of L10-ordered FePd and FePt intermetallics. Substantial effect of magnetic ordering on the activation energy for chemical ordering was revealed in FePd. A discontinuous change of ordering dynamics was detected in FePt between 800 and 830 K. The results are consistent with the data of Fe* diffusion in FePt multilayer examined by means of nuclear resonant scattering in grazing-incidence geometry (GINRS). Monte Carlo (MC) simulations of “order –order” processes in L10-ordered bulk FePd and FePt and nano-layered FePt have been carried out using Glauber dynamics with vacancy mechanism of atomic jumps. Multi-timescale “order – order” relaxations observed in the bulk were predominated in nanolayers by a reorientation of the initial z-variant L10 superstructure into a mixture of x- and y-variants.

Authors: Riethmueller J. , Dehm G. , Affeldt E. E. , Arzt E. 
Published: March 2022

Abstract
The performance of thermal barrier coatings (TBCs) in jet engines is strongly influenced by thermal and mechanical properties of the bond coat. In this investigation two different types of Pt-modified diffusion coatings developed for application as oxidation protection or as a bond coat in TBC systems were studied with respect to their microstructure and mechanical properties. The microstructural analyses based on different microscopy techniques and X-ray diffraction measurements revealed distinct differences between the two coatings: the coating aluminized by a gas phase process consisted solely of a (NiPt)Al phase, while the coating fabricated by pack-cementation consisted mainly of the two phases (NiPt)Al and Al2Pt, leading to a higher strength in comparison with the single-phase coating. In contrast, the ductility determined with 3-point bend tests between room temperature and 700 °C was clearly better for the single-phase coating. Additionally, the substrate curvature of coated sheets was measured to gain some information about coating stresses.
Phase transformations of iron nitrides at low temperatures (< 700 K) – application of mechanical mixtures of powders of nitrides and iron
Authors: Leineweber Andreas , Aufrecht Jochen , Mittemeijer Eric Jan 
Published: March 2022

Abstract
Annealing at low temperatures (T < 670 K) of mixtures of iron nitride powders and iron powder is shown to induce phase transformations through nitrogen transfer between different powder particles. This nitrogen transfer occurs via loose mechanical contact points between different powder particles; nitrogen transport via the gas phase can be excluded. Unique scientific possibilities offered by this type of phase transformation studies are discussed.
