Numerical Simulation of Permanent Magnet Method: Applicability to $j_{\rm C}$-Measurement in HTS Thick Film

Applicability of the permanent magnet method to the measurement of the critical current density in a high-temperature superconducting (HTS) thick film has been investigated numerically. A numerical code has been developed for analyzing the shielding current density in a HTS sample. By using the code, the permanent magnet method is numerically simulated. The results of computations show that the maximum repulsive force is roughly proportional to the critical current density for the case with a low critical current density. On the other hand, the proportional relation does not hold for the case with a high critical current density. In other words, there exists an upper limit of the measurable critical current density. Furthermore, it is found that the limit increases with the strength of the permanent magnet. This means that applicability of the permanent magnet method to a thick film can be considerably improved by means of a strong magnet.
Role of palmar dermatoglyphics in detecting precancerous lesions

Genetics play most important role in the determination of palmer dermatoglyphics. Oral submucous fibrosis (OSMF) is due to consumption of areca nut. Environmental and Hereditary factors causing OSMF may lead to peculiarities in the dermatoglyphic patterns. Dermatoglyphics can identify the disease at the earliest, and preventive measures can be instituted for subjects having OSMF, leukoplakia etc.3
Theoretical Interpretation of Polarized Light-Induced Supramolecular Orientation on the Basis of Normal Mode Analysis of Azobenzene as Hybrid Materials in PMMA with Chiral Schiff Base Ni(II), Cu(II), and Zn(II) Complexes

We have prepared hybrid materials of azobenzene and chiral Schiff base Ni(II), Cu(II), and Zn(II) complexes and investigated their linearly or circularly polarized UV (ultraviolet) light-induced supramolecular orientation with polarized electronic and IR spectra or CD (circular dichroism) spectra. The experimental FT-IR (Fourier transfer-infrared) spectra of azobenzene molecules were recorded at room temperature, and the results were compared with quantum chemical theoretical values using B3LYP, M052X, and M062X DFT (density functional theory) methods. The interaction of azobenzene with PMMA was simulated. Molecular geometry, vibrational wavenumbers, and thermodynamic parameters were calculated in all these systems. With the help of specific scaling procedures for the computed wavenumbers, the experimentally observed FT-IR bands were analyzed and assigned to different normal modes of the molecule. Most modes had wavenumbers in the expected range, and the error obtained was in general very low. Several general conclusions were deduced.
Preliminary sensory evaluation of salty crackers with grape pomace flour

Grape pomace, a by-product of winemaking, contains numerous chemical compounds with high nutritional value and potential benefits for human health, which enable its use for product enrichment in different industries from cosmetics to food. The aim of this study was to incorporate the grape pomace flour of the Touriga Nacional and Arinto grapes varietals from the Alentejo region of Portugal in a recipe for salty crackers, which were submitted to sensory evaluation by applying a hedonic test to 53 individuals. The results of the evaluation show a clear tendency of preference for the crackers with 10% of grape pomace flour, both in the Touriga Nacional and Arinto samples, which presented the highest result averages.
Integer Charge Transfer and Hybridization at an Organic Semiconductor/Conductive Oxide Interface

We investigate the prototypical hybrid interface formed between PTCDA and conductive n-doped ZnO films by means of complementary optical and electronic spectroscopic techniques. We demonstrate that shallow donors in the vicinity of the ZnO surface cause an integer charge transfer to PTCDA, which is clearly restricted to the first monolayer. By means of DFT calculations, we show that the experimental signatures of the anionic PTCDA species can be understood in terms of strong hybridization with localized states (the shallow donors) in the substrate and charge back-donation, resulting in an effectively integer charge transfer across the interface. Charge transfer is thus not merely a question of locating the Fermi level above the PTCDA electron-transport level but requires rather an atomistic understanding of the interfacial interactions. The study reveals that defect sites and dopants can have a significant influence on the specifics of interfacial coupling and thus on carrier injection or extraction.
IN VITRO ANTIOXIDANT ACTIVITY OF SARACA ASOCA ROXB. DE WILDE STEM BARK EXTRACTS FROM VARIOUS EXTRACTION PROCESSES

Antioxidant potential of various extracts i.e. ethanolic, hydroalcoholic and acetone prepared by different extraction methods (Soxhlet extraction, Ultrasonication extraction and Microwave assisted extraction) of stem bark of Saraca asoca Roxb. De Wilde was studied by using DPPH (1,1, diphenyl-2 picryl hydrazyl) in-vitro model. The highest IC50 value 193.88 µg/ml were showed by hydroalcoholic (ethanol 60%) extract prepared by soxhlet extraction method. The acetone extract prepared by ultrasonication extraction method exhibited the lowest IC50 value 97.82 µg/ml. The results indicate that the antioxidant property of the extract may be due to high content of phenolic compounds.
A Fuzzy Multi-Criteria Decision-Making Approach for Power Generation Problem Analysis

The abundance of different energy sources such as coal, natural gas, and crude oil are in the Africa region, yet one of the lowest electric energy per capita consumption. Different factors have been attributed to this abysmal energy failure in the literature, leading to her slow economic and industrial advancement. These factors include poor maintenance of power generation infrastructure and lack of policy continuity, among others. The purpose of this article is to prioritize these power generation problems for proper budgetary allocation by managers of electric power. The fuzzy VIKOR technique is presented for the evaluation and ranking of these power generation problems. The analysis showed that poor maintenance is the most critical challenge of bedeviling power generation in Nigeria. The Fuzzy VIKOR produces the same result as the classical VIKOR used previously in resolving the problem. The proposed technique addresses the challenge of uncertainty and subjectivity by applying linguistic variables in the decision-making process, which the classical VIKOR is incapable of handling.
Climate Transition Risk, Profitability and Stock Prices

We investigate whether climate transition risk is reflected in the financial performance and cross-section pricing of publicly-traded European and US firms. Using a firm-level carbon risk score (CRS) that assesses the vulnerability of a firm’s value to transition to a low-carbon economy, we find that firms with the lowest transition risk exposures perform better financially, and that European firms are more sensitive to transition risks than US firms. We also find that stocks with low exposure to transition risk offer greater returns to investors, consistent with the fact that stock prices of firms do not adequately reflect underlying climate transition risk. Relative financial performance of less vulnerable firms and underreaction effects to transition risk decreased after COP21.
Investigation of the hepatic development in the coculture of hiPSCs-derived LSECs and HLCs in a fluidic microenvironment

Interactions between the different liver cell types are critical to the maintenance or induction of their function in vitro. In this work, human-induced Pluripotent Stem Cells (hiPSCs)-derived Liver Sinusoidal Endothelial Cells (LSECs) and Hepatocytes-Like Cells (HLCs) were cultured and matured in a microfluidic environment. Both cell populations were differentiated in Petri dishes, detached, and inoculated in microfluidic biochips. In cocultures of both cell types, the tissue has exhibited a higher production of albumin (3.19 vs 5.31 μg/mL/106 cells in monocultures and cocultures) as well as a higher inducibility CYP450 over monocultures of HLCs. Tubular-like structures composed of LSECs and positive for the endothelial marker PECAM1, as well as a tissue more largely expressing Stabilin-2 were detected in cocultures only. In contrast, monocultures exhibited no network and less specific endothelial markers. The transcriptomic analysis did not reveal a marked difference between the profiles of both culture conditions. Nevertheless, the analysis allowed us to highlight different upstream regulators in cocultures (SP1, EBF1, and GATA3) and monocultures (PML, MECP2, and NRF1). In cocultures, the multi-omics dataset after 14 days of maturation in biochips has shown the activation of signaling related to hepatic maturation, angiogenesis, and tissue repair. In this condition, inflammatory signaling was also found to be reduced when compared to monocultures as illustrated by the activation of NFKB and by the detection of several cytokines involved in tissue injury in the latter. Finally, the extracted biological processes were discussed regarding the future development of a new generation of human in vitro hepatic models.
Temporal vs. spatial variation in stress-associated metabolites within a population of climate-sensitive small mammals

ABSTRACT Temporal variation in stress might signify changes in an animal’s internal or external environment, while spatial variation in stress might signify variation in the quality of the habitats that individual animals experience. Habitat-induced variations in stress might be easiest to detect in highly territorial animals, and especially in species that do not take advantage of common strategies for modulating habitat-induced stress, such as migration (escape in space) or hibernation (escape in time). Spatial and temporal variation in response to potential stressors has received little study in wild animals, especially at scales appropriate for relating stress to specific habitat characteristics. Here, we use the American pika (Ochotona princeps), a territorial small mammal, to investigate stress response within and among territories. For individually territorial animals such as pikas, differences in habitat quality should lead to differences in stress exhibited by territory owners. We indexed stress using stress-associated hormone metabolites in feces collected non-invasively from pika territories every 2 weeks from June to September 2018. We hypothesized that differences in territory quality would lead to spatial differences in mean stress and that seasonal variation in physiology or the physical environment would lead to synchronous variation across territories through time. We used linear mixed-effects models to explore spatiotemporal variation in stress using fixed effects of day-of-year and broad habitat characteristics (elevation, aspect, site), as well as local variation in habitat characteristics hypothesized to affect territory quality for this saxicolous species (talus depth, clast size, available forage types). We found that temporal variation within territories was greater than spatial variation among territories, suggesting that shared seasonal stressors are more influential than differences in individual habitat quality. This approach could be used in other wildlife studies to refine our understanding of habitat quality and its effect on individual stress levels as a driver of population decline.
The Role of Milk Protein and Whey Permeate in Lipid-based Nutrient Supplements on the Growth and Development of Stunted Children in Uganda: A Randomized Trial Protocol (MAGNUS)

ABSTRACT Stunting is associated with cognitive impairment and later chronic disease. Previous trials to prevent stunting have had little effect, and no trials seem to have provided larger amounts of energy and high-quality proteins to already stunted children. We aimed to assess the effects of milk protein (MP) and whey permeate (WP) in large-quantity lipid-based nutrient supplements (LNS-LQ), among stunted children, on linear growth and child development. This was a randomized, double-blind, 2-by-2 factorial trial. Stunted children aged 12–59 mo from eastern Uganda (n = 750) were randomly assigned to receive 100 g LNS-LQ with or without MP and WP (n = 4 × 150) or no supplement (n = 150) for 3 mo. The primary outcomes were change in knee-heel and total length. Secondary outcomes included child development, body composition, anthropometry, and hemoglobin. Micronutrient status, intestinal function, and microbiota were also assessed. Our findings will contribute to an understanding of the role of milk ingredients and LNS in linear catch-up growth. This trial was registered at www.isrctn. com as ISRCTN13093195.
Media exposure predicts acute stress and probable acute stress disorder during the early COVID-19 outbreak in China

Background The COVID-19 has led to unprecedented psychological stress on the general public. However, the associations between media exposure to COVID-19 and acute stress responses have not been explored during the early COVID-19 outbreak in China. Methods An online survey was conducted to investigate the relationships between media exposure to COVID-19 and acute stress responses, and to recognize associated predictors of acute stress responses on a sample of 1,450 Chinese citizens from February 3 to February 10, 2020. Media exposure questionnaire related to COVID-19 was developed to assess media exposure time, media exposure forms and media exposure content. The Stanford Acute Stress Reaction Questionnaire (SASRQ) was used to measure acute stress responses, including continuous acute stress symptom scores and the risk of probable acute stress disorder (ASD). A series of regression analyses were conducted. Results Longer media exposure time and social media use were associated with higher acute stress and probable ASD. Viewing the situation of infected patients was associated with higher acute stress, whereas viewing the latest news about pandemic data was associated with lower odds of probable ASD. Being females, living in Hubei Province, someone close to them diagnosed with COVID-19, history of mental illness, recent adverse life events and previous collective trauma exposure were risk factors for acute stress responses. Conclusions These findings confirmed the associations between indirect media exposure to pandemic events and acute stress responses. The governments should be aware of the negative impacts of disaster-related media exposure and implement appropriate interventions to promote psychological well-being following pandemic events.

Thromboprophylaxis with rivaroxaban in patients with malignancy and central venous lines (TRIM‐Line): A two‐center open‐label pilot randomized controlled trial

Central venous catheter (CVC) insertion is an important risk factor for venous thromboembolism (VTE) among patients with cancer. Routine use of primary thromboprophylaxis in this patient population is not currently recommended. We sought to assess the feasibility of conducting a randomized controlled trial (RCT) assessing the safety and efficacy of rivaroxaban (10 mg daily) to prevent VTE complications in this patient population.
Pulse wave velocity, carotid intima media thickness and flow-mediated dilation in Takayasu arteritis: a systematic review

Introduction Takayasu arteritis (TA) is a chronic vasculitis associated with an increased cardiovascular risk. The measurement of pulse wave velocity (PWV), carotid artery intima-media thickness (CIMT) and flow-mediated dilatation (FMD) are generally used for evaluating the cardiovascular risk. The application of these measurements to TA patients remains undetermined. Material and methods Clinical studies that reported the PWV, CIMT and FMD levels in TA patients, which were published prior to 2021, were summarized using PubMed. Results Fifteen studies were eligible. Overall, in TA patients, the PWV and CIMT levels were significantly higher and the FMD levels were significantly lower compared to controls. Part of the studies showed that the disease activity of TA was significantly associated with the PWV, CIMT or FMD levels. Conclusions The PWV, CIMT and FMD measurements could be useful for evaluating the cardiovascular risk in TA patients. Further studies to determine the proper use of these measurements are warranted.
Mapping open knowledge institutions: an exploratory analysis of Australian universities

While the movement for open research has gained momentum in recent years, there remain concerns about the broader commitment to openness in knowledge production and dissemination. Increasingly, universities are under pressure to transform themselves to engage with the wider community and to be more inclusive. Open knowledge institutions (OKIs) provide a framework that encourages universities to act with the principles of openness at their centre; not only should universities embrace digital open access (OA), but also lead actions in cultivating diversity, equity, transparency and positive changes in society. This leads to questions of whether we can evaluate the progress of OKIs and what are potential indicators for OKIs. As an exploratory study, this article reports on the collection and analysis of a list of potential OKI indicators. Data for these indicators are gathered for 43 Australian universities. The indicators provide high-dimensional and complex signals about university performances. They show evidence of large disparities in characteristics such as Indigenous employment and gender equity, and a preference for repository-mediated OA across Australian universities. We demonstrate use of the OKI evaluation framework to categorise these indicators into three platforms of diversity, communication and coordination. The analysis provides new insights into the Australian open knowledge landscape and ways of mapping different paths of OKIs.
Growth and Partial Reduction of Sm2O3(111) Thin Films on Pt(111): Evidence for the Formation of SmO(100)

We investigated the growth and partial reduction of Sm2O3(111) thin films on Pt(111) using low energy electron diffraction (LEED) and scanning tunneling microscopy (STM). We find that the Sm2O3(111) films are high quality and grow in a defective fluorite structure wherein the Sm cations adopt a hexagonal (1.37 × 1.37) lattice in registry with the Pt(111) surface, while oxygen vacancies are randomly distributed within the film. STM measurements show that Sm2O3(111) film growth on Pt(111) occurs by the Stranski-Krastanov mechanism, in which a single O–Sm–O trilayer initially forms, followed by the growth of well-defined, multilayer islands. The Sm2O3(111) films undergo partial reduction during annealing at 1000 K in ultrahigh vacuum. LEED and STM provide evidence that a fraction of the Sm2O3 in the first layer, closest to the Pt(111) substrate, decomposes to produce well-ordered domains of rocksalt SmO(100) during reduction, and that Sm2O3 from the third and higher layers concurrently spreads onto the first.
Sequential treatment of chronic obstructive pulmonary disease concurrent with respiratory failure by high-flow nasal cannula therapy.

OBJECTIVE To analyze the efficacy of sequential treatment with high-flow nasal cannula (HFNC) in chronic obstructive pulmonary disease (COPD) concomitant with respiratory failure. METHODS A total of 100 COPD patients concomitant with respiratory failure requiring invasive mechanical ventilation from June 2019 to May 2020 in our hospital were enrolled and then divided into two groups according to the random number table, with 50 in each group. Pulmonary infection control window (PIC) was used as a switching point for sequential ventilation. The control group (CNG) received non-invasive positive pressure ventilation (NIPPV), while the study group (SG) underwent HFNC. The efficacy, complications and 48 h reintubation rate of the two groups were statistically analyzed. The respiratory parameters, diaphragmatic parameters, diaphragmatic excursion during quiet breathing (DEq), diaphragmatic rapid shallow breathing index (D-RSBI), COPD score (CAT), 6-min walk test (6 MWT) score (Borg), General Comfort Questionnaire (GCQ), sputum viscosity, and serum factors were observed before intubation and after 48 hours of intubation. RESULTS The overall response rate (94.00%) in SG was higher than that in CNG (80.00%) (P < 0.05); SG had lower RR, PaCO2 and D-RSBI at 48 hours after extubation and higher PaO2/FiO2 and DEd than CNG (P < 0.05); SG exhibited lower CAT and Borg at 48 hours after extubation and higher GCQ score than CNG (P < 0.05); SG had lower sputum viscosity at 48 hours after extubation than CNG (P < 0.05); SG showed lower ET-1, NLR and NT-proBNP levels at 48 hours after extubation than CNG (P < 0.05). CONCLUSION HFNC sequential therapy is effective and safe in the treatment of COPD concomitantly with respiratory failure. It can improve respiratory function and diaphragmatic function, reduce dyspnea and fatigue, reduce sputum viscosity, regulate serum factors, and make patients enjoy higher comfort.

Effects of schistosomes on host anti-viral immune response and the acquisition, virulence, and prevention of viral infections: A systematic review

Although a growing number of studies suggest interactions between Schistosoma parasites and viral infections, the effects of schistosome infections on the host response to viruses have not been evaluated comprehensively. In this systematic review, we investigated how schistosomes impact incidence, virulence, and prevention of viral infections in humans and animals. We also evaluated immune effects of schistosomes in those coinfected with viruses. We screened 4,730 studies and included 103. Schistosomes may increase susceptibility to some viruses, including HIV and Kaposi’s sarcoma-associated herpesvirus, and virulence of hepatitis B and C viruses. In contrast, schistosome infection may be protective in chronic HIV, Human T-cell Lymphotropic Virus-Type 1, and respiratory viruses, though further research is needed. Schistosome infections were consistently reported to impair immune responses to hepatitis B and possibly measles vaccines. Understanding the interplay between schistosomes and viruses has ramifications for anti-viral vaccination strategies and global control of viral infections.
