Evolution of magnetic loss with annealing temperature in FeSiAl/carbonyl iron soft magnetic composite

ABSTRACT The evolution of magnetic loss of FeSiAl/carbonyl iron powder cores annealed at different temperatures was investigated. The experimental results reveal that the magnetic permeability of FeSiAl/carbonyl iron core increases as the annealing temperature increases, but it almost remains constant when annealing temperature higher than 650°C. The magnetic loss of the core first decreases with the increase of the annealing temperature, reaches a minimum at about 640°C, and then starts to increase with further annealing temperature increasing. It is found in loss separation that both hysteresis loss and excess loss decrease with the increase of annealing temperature before 640°C, which can be attributed to the reduction of effective anisotropy caused by stress relief. However, the eddy current loss increases with annealing temperature increasing when it is higher than 650°C, which may be the result of the degradation of the surface insulation layer caused by the high temperature annealing.
Associations between Serum Betaine, Methyl-Metabolizing Genetic Polymorphisms and Risk of Incident Type 2 Diabetes: A Prospective Cohort Study in Community-Dwelling Chinese Adults

Previous studies have explored associations between betaine and diabetes, but few have considered the effects of genes on them. We aimed to examine associations between serum betaine, methyl-metabolizing genetic polymorphisms and the risk of type 2 diabetes in Chinese adults. This prospective study comprised 1565 subjects aged 40–75 without type 2 diabetes at baseline. Serum betaine was measured by high-performance liquid chromatography tandem mass spectrometry. Genotyping of methyl-metabolizing genes was detected by Illumina ASA-750K arrays. Cox proportional hazards model was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). During a median of 8.9 years of follow-up, 213 participants developed type 2 diabetes. Compared with participants in the lowest quartile of serum betaine, those in the highest quartile had lower risk of type 2 diabetes, adjusted HRs (95%CIs) was 0.46 (0.31, 0.69). For methylenetetrahydrofolate reductase (MTHFR) G1793A (rs2274976) and MTHFR A1298C (rs1801131), participants carrying 1793GA + AA and 1298AC + CC had lower risk of type 2 diabetes. Interactions of serum betaine and genotype of MTHFR G1793A and MTHFR A1298C could be found influencing type 2 diabetes risk. Our findings indicate that higher serum betaine, mutations of MTHFR G1793A and A1298C, as well as the joint effects of them, are associated with lower risk of type 2 diabetes.
Measuring business process innovations among tourism enterprises in the Czech Republic: a PLS-GLM approach

The Czech Republic has experienced momentous tourism expansion in recent years. Nevertheless, there is a lack of empirical investigation about this development. Innovations are an essential factor for the sustainable development of the tourism industry in the Czech Republic. The paper expounds on the effect of technical and process innovations among the tour and travel companies in the Czech Republic. The study surveyed 96 travel and tour operators aged 18-40 working in the various small, medium, and large travel agencies to determine their perceptions towards innovation in their respective travel businesses. A two-phased statistical process that combined PLS-SEM and GLM examined the responses of the individuals. It revealed that technical innovation had a robust and positive relationship with corporate profitability. Process innovation remains a grey area for Czech travel businesses. The study builds upon the Process Innovations in Colombia's Tourist Enterprises or PICTE framework to induct critical insights for travel agencies and tour operators to provide these businesses a way forward and make them more competitive and sustainable. It has been observed that tourism businesses that were not early adopters of disruptive technologies became vulnerable to market mechanisms. Therefore, the relevance of this study is further accentuated. COVID-19 has accelerated the climate of VUCA (volatility, uncertainty, complexity, and ambiguity) among Czech tour and travel operators, many of whom winded up or downsized operations. Many of these firms were in the medium and small segments. In light of the present situation, it becomes imperative that travel service providers invest in modern technologies and ensure the same diffusion among the staff. The paper gave the strategies towards human resource mapping and digital transformations for the best interest of the tourism industry. Future studies are recommended to focus on longitudinal measures towards understanding innovation propensities among small and medium-sized businesses. Mixed method studies are encouraged to comprehend the corporate dynamics of change management.
Sex Moderated Mediation of the Musculoskeletal Fitness in Relationship between High-Intensive Interval Training Performing during Physical Education Classes and Cardiorespiratory Fitness in Healthy Boys and Girls

High-intensive interval training (HIIT) is indicated as a means of improving cardiorespiratory fitness (CRF) and musculoskeletal fitness (MSF). The relationship between CRF and MSF was examined too. Little is known about gaining CRF from HIIT independence of MSF in adolescents. Therefore, this study is aimed at investigating whether MSF mediated the relationship between HIIT and CRF and whether sex moderate this relation. The study sample included 122 individuals (45 boys, 77 girls) 16.12 ± 0.38 years of secondary school age. Participants were assigned to the HIIT intervention or control groups. The intervention lasted 14 minutes during one physical education lesson per week for ten weeks. Outcome and potential mediator were residual changes calculated from pre- and postintervention results of MSF components: handgrip (HG), sit-ups (ABS), sit-and-reach (FL), vertical jump (VJ), and Harvard step-test representing cardiorespiratory fitness (CRF). MSF index (MSFI) was calculated as a construct, agglomerating all MSF, and tested its usefulness. HIIT significantly impacted CRF in boys and girls (B = 2.32, p = 0.032; B = 2.28, p = 0.005, respectively). The impact of the HIIT program on the ABS and FL was observed only in girls. The moderation effect of sex was confirmed. Significant effect of HIIT on CRF decreased (Bdirect < Btotal) and was no significant after including FL (B = 1.46, p = 0.62)—complete mediation, but no ABS (B = 2.97, p = 0.001)—partial mediation. CRF was mediated by changes in ABS (B = 2.28, p < 0.001) and FL (4.18, p < 0.001). MSFI was not mediating; its usefulness was limited. HIIT is an effective tool in the development of CRF in both sexes. MSF played a limited role in the relationship between HIIT and CRF. It suggested different mechanisms in both sexes: girls who performed better to the HIIT had better values of FL and ABS, but not boys. HIIT intervention involved modifications in ABS or FL, which also influenced the increase of CRF.
Exploring Risks Associated With Bullying Perpetration Among Hispanic/Latino Adolescents: Are They Similar for Foreign-Born and U.S.-Born?

Previous research indicates that racial and ethnic minority adolescents show an increased risk for bullying involvement. However, research on racial and ethnic differences in bullying has mainly focused on the differences between Whites and African American adolescents in the U.S.A. Research on the bullying perpetration of foreign-born students is scarce. To fill this gap in the literature, this study utilizes the immigrant paradox to compare the prevalence rates and correlates of bullying perpetration between foreign-born and U.S.-born Hispanic/Latino adolescents. Data from the Health Behavior in School-Aged Children, 2009 to 2010 cohort study in the United States were used. The sample included 1,451 Hispanic/Latino adolescents from which 287 were foreign-born (Mage = 13.32, SD = 1.68; 55% girls) and 1,164 were U.S.-born (Mage = 13.05, SD = 1.68; 51.4% girls). Self-report questionnaires were administered to measure bullying involvement, substance abuse, befriending deviant peers, physical fight, demographic variables, and family characteristics. Findings showed that foreign-born adolescents did not differ from U.S.-born Hispanic/Latino adolescents (9.8% vs. 9.9%) regarding bullying perpetration. In addition, logistic regression analyses revealed that only bullying victimization was a common correlate for bullying perpetration across both groups. For foreign-born Hispanic/Latino adolescents, only befriending deviant peers was significantly associated with bullying perpetration. For the U.S.-born group, alcohol use and physical fights increased the odds of bullying perpetration. Implications for future research (e.g., the significance of the intersection of race, ethnicity, and socioeconomic class) and practice (e.g., the need to foster a positive school climate) will be discussed.
Removal of paraquat from aqueous solutions by plant extracts as an ecofriendly approach

Abstract Paraquat is a very water-soluble herbicide widely used in agricultural and nonagricultural lands. The removal of paraquat from polluted water is very essential. Hence, three experiments were arranged separately to investigate the ability of plant extracts include Aloe vera, Portulaca grandiflora, kalanchoe daigremontiana, Sedum rubotinctum, Brassica rapa var. rapa, Helxine soleirolii, Brassica oleracea var. capitata, Crassula ovate, Aptenia cordifolia, Tradescantia albiflora to the removal of paraquat (PQ) from water. In the 1st experiment, High-performance liquid chromatography was used to determine the removal rate of PQ by using plant extracts. In the 2nd and 3rd experiments, PQ solutions were subjected to plant extracts treatments and then spray on the leaves of littleseed canarygrass (Phalaris minor) under greenhouse and field conditions, respectively. In general, the results of these experiments revealed that all plant extracts resulted in higher PQ removal from water compared to control. The maximum removal of PQ was observed at pH 11, 25 °C, 30 Min, and 0.2 mL in the presence of plant extracts. In the presence of P. grandiflora, C. ovate, k. daigremontiana, A. cordifolia, H. soleirolii, Aloe vera, S. rubotinctum, B. oleracea var. capitata, B. rapa var. rapa, and T. albiflora plant extracts, PQ removal from water increased to 68.34%, 65.45%, 63.97%, 59.81%, 59.29%, 55.44%, 52.06%, 50.34%, 48.86%, and 46.44% under normal conditions and 79.71%, 78.61%, 78.00%, 75.83%, 74.66%, 72.12%, 71.57%, 71.02%, 69.35%, and 68.73% under optimum conditions, respectively. Results of the 2nd and 3rd experiments were demonstrated a decrease in PQ performance on littleseed canarygrass control. It can be concluded that plant extracts can reduce the residual of PQ in water bodies.
Retrospective Cohort Analysis of the Effect of Antimicrobial Stewardship on Postoperative Antibiotic Therapy in Complicated Intra-Abdominal Infections: Short-Course Therapy Does Not Compromise Patients’ Safety

Background: Recent evidence suggests that short-course postoperative antibiotic therapy (PAT) of intra-abdominal infections is non-inferior considering clinical outcomes. The aim of this study was to compare the outcome of short vs. long PAT in complicated intra-abdominal infections (cIAIs) without sepsis. Methods: We performed a single center-quality improvement study at a 1500 bed sized university hospital in Bavaria, Germany, with evaluation of the length of antibiotic therapy after emergency surgery on cIAIs with adequate source control during 2016 to 2018. We reviewed a total of 260 cases (160 short duration vs. 100 long duration). The antibiotic prescribing quality was assessed by our in-house antimicrobial stewardship team (AMS). Results: No significant differences of patient characteristics were observed between short and long PAT. The frequency of long PAT declined during the observation period from 48.1% to 26.3%. Prolongation of PAT was not linked with any clinical benefits, on the contrary clinical outcome of patients receiving longer regimes were associated with higher postoperative morbidity. AMS identified additional educational targets to improve antibiotic prescribing quality on general wards like unnecessary postoperative switches of antibiotic regimes, e.g., unrequired switches to oral antibiotics as well as prolongation of PAT due to elevated CRP. Conclusion: Short-course antibiotic therapy after successful surgical source control in cIAIs is safe, and long-duration PAT has no beneficial effects.
Numerical Investigation into Lateral Behavior of Monopile Due to Scour Enhanced: Role of State-Dependent Dilatancy

The removal of soil during scouring is crucial to the lateral resistance of piles in bridges of railways or highways. In this process, dilatancy of the interface soil induces variation in normal stress, which in turn influences the interface soil lateral resistance. Due to the lack of analysis in previous studies in terms of cohesionless soil state (i.e., relative density and stress level) in remaining soil after scouring, it is difficult to simulate the properties and behavior of interface soil. The objective of this study is to explain the change of the sand state at the compression interface after scouring, quantify the stress-strain characteristics of the pile during this period and eventually present the prediction p-y curves of the lateral service capacity. The state-dependent constitutive model for saturated sand is employed, combined with the 3D finite element simulation, and the state development of the remaining soil is exhibited. The enhancement of dilation and stress relief of the remaining shallow horizon eventually gives rise to the reduction of the lateral resistance. In addition, the remaining overburden soil surrounding the pile restricts the interface soil, enlarging the normal stress and strengthening the deep horizon. Then, the friction angle considered the influence of state-dependent changes is used to quantify the hyperbolic p-y curves.
Automatic Fungi Recognition: Deep Learning Meets Mycology

The article presents an AI-based fungi species recognition system for a citizen-science community. The system’s real-time identification too — FungiVision — with a mobile application front-end, led to increased public interest in fungi, quadrupling the number of citizens collecting data. FungiVision, deployed with a human-in-the-loop, reaches nearly 93% accuracy. Using the collected data, we developed a novel fine-grained classification dataset — Danish Fungi 2020 (DF20) — with several unique characteristics: species-level labels, a small number of errors, and rich observation metadata. The dataset enables the testing of the ability to improve classification using metadata, e.g., time, location, habitat and substrate, facilitates classifier calibration testing and finally allows the study of the impact of the device settings on the classification performance. The continual flow of labelled data supports improvements of the online recognition system. Finally, we present a novel method for the fungi recognition service, based on a Vision Transformer architecture. Trained on DF20 and exploiting available metadata, it achieves a recognition error that is 46.75% lower than the current system. By providing a stream of labeled data in one direction, and an accuracy increase in the other, the collaboration creates a virtuous cycle helping both communities.
Modeling allelic diversity of multiparent mapping populations affects detection of quantitative trait loci

Abstract The search for quantitative trait loci that explain complex traits such as yield and drought tolerance has been ongoing in all crops. Methods such as biparental quantitative trait loci mapping and genome-wide association studies each have their own advantages and limitations. Multiparent advanced generation intercross populations contain more recombination events and genetic diversity than biparental mapping populations and are better able to estimate effect sizes of rare alleles than association mapping populations. Here, we discuss the results of using a multiparent advanced generation intercross population of doubled haploid maize lines created from 16 diverse founders to perform quantitative trait loci mapping. We compare 3 models that assume bi-allelic, founder, and ancestral haplotype allelic states for quantitative trait loci. The 3 methods have differing power to detect quantitative trait loci for a variety of agronomic traits. Although the founder approach finds the most quantitative trait loci, all methods are able to find unique quantitative trait loci, suggesting that each model has advantages for traits with different genetic architectures. A closer look at a well-characterized flowering time quantitative trait loci, qDTA8, which contains vgt1, highlights the strengths and weaknesses of each method and suggests a potential epistatic interaction. Overall, our results reinforce the importance of considering different approaches to analyzing genotypic datasets, and shows the limitations of binary SNP data for identifying multiallelic quantitative trait loci.
In0.53Ga0.47As MOSFETs with 5 nm channel and self-aligned source/drain by MBE regrowth

In0.53Ga0. 47As MOSFETs with 5 nm channel and self-aligned source/drain by MBE regrowth Uttam Singisetti InGaAs has been extensively studied as a potential channel material for sub22nm gate length VLSI MOSFETs because of its low electron effective mass (m∗) hence high electron velocity (υ). At 22 nm gate lengths, a maximum 1 nm EOT dielectric and 5 nm thick channel with strong vertical confinement are required for low subthreshold swing and low drain induced barrier lowering (DIBL). Most reported InGaAs MOSFETs and HEMTs have typically ≥ 10 nm channel thickness. The source/drain (S/D) junctions must be very shallow (∼ 5 nm) with abrupt vertical and lateral profiles, yet extremely low (∼ 50 Ω − μm) source access resistance and consequently very low (∼ 1 Ω − μm) contact and ( ∼ 400 Ω/ ) sheet resistivities are required to minimize degradation of the drive current (Id) and transconductance (gm). Such parameters are difficult to achieve in InGaAs by ion implantation of the n source/drain, particularly if an InAlAs bottom confinement layer is used. Source/drain contacts must also be self-aligned to the gate, yet there is no known equivalent of self-aligned silicides in III-V materials. This dissertation addresses these requirements and shows InGaAs MOSFETs with
Regulation of the Receptor Tyrosine Kinase AXL in Response to Therapy and Its Role in Therapy Resistance in Glioblastoma

The receptor tyrosine kinase AXL (RTK-AXL) is implicated in therapy resistance and tumor progression in glioblastoma multiforme (GBM). Here, we investigated therapy-induced receptor modifications and how endogenous RTK-AXL expression and RTK-AXL inhibition contribute to therapy resistance in GBM. GBM cell lines U118MG and SF126 were exposed to temozolomide (TMZ) and radiation (RTX). Receptor modifications in response to therapy were investigated on protein and mRNA levels. TMZ-resistant and RTK-AXL overexpressing cell lines were exposed to increasing doses of TMZ and RTX, with and without RTK-AXL tyrosine kinase inhibitor (TKI). Colorimetric microtiter (MTT) assay and colony formation assay (CFA) were used to assess cell viability. Results showed that the RTK-AXL shedding product, C-terminal AXL (CT-AXL), rises in response to repeated TMZ doses and under hypoxia, acts as a surrogate marker for radio-resistance. Endogenous RTX-AXL overexpression leads to therapy resistance, whereas combination therapy of TZM and RTX with TKI R428 significantly increases therapeutic effects. This data proves the role of RTK-AXL in acquired and intrinsic therapy resistance. By demonstrating that therapy resistance may be overcome by combining AXL TKI with standard treatments, we have provided a rationale for future study designs investigating AXL TKIs in GBM.
Intuitive anger in the context of crime and punishment

ABSTRACT Anger is a key emotion in terms of understanding public responses toward crime: it is frequently mobilized in public discourses and is elicited by specific incidents. This study focuses on intuitive anger: a rapidly emerging negative emotional response that eschews principles of punishment but nevertheless contributes to punitiveness. This study uses facial electromyography to measure intuitive anger, and assess its effect on punitiveness drawing on data collected among university students in Canada (N = 87). The study’s repeated-measures experimental design allows for testing the hypotheses that: (i) individuals will experience greater intuitive angry responses when making punitive decisions for purported ‘stereotypical criminals’ and that (ii) anger will appear early in the decision-making process, and lead to more punitive decisions. The results of crossed-multilevel regression models provide evidence of the manifestation of anger within half of a second of individuals’ engagement in punitive decision-making. Intuitive anger follows principles that are central to intergroup relations, although it was not found to be predictive of rapid punitive decisions. The findings are discussed in terms of the moral and social implications of intuitive anger in the context of punitiveness toward crime.
