Abstract
We have found out that vacuum exposure of YBa2Cu3O7‒δ thin epitaxial films at 300 K for 24 hours decreases oxygen content and induces changes in their crystal structure depending on the films synthesis conditions. YBa2Cu3O7‒δ films on SrTiO3 (100) substrates were synthesized by pulsed laser deposition. The crystal structure was studied using XRD technique. Additional maxima of diffraction peak (005) before and after vacuum exposure indicate the presence of regions with different oxygen content; and the change in the shape of the rocking curves indicate a change in the crystallites orientation. After vacuum exposure, the oxygen deficiency δ in the films increased from ~0.01 to 0.6 for films with a crystallites size of 2-10 nm and from ~0.25−0.35 to 0.6 for crystallites size of 500−1000 nm. The appearance of a residual resistance after the superconducting transition in the dependence R(T) may be explained by the fact that oxygen loss mainly in the boundary regions of the crystallites takes place, so that their boundaries become dielectric, while the crystallites themselves remain superconductive. Based on the data of X—ray diffraction analysis, as well as resistive measurements, we have come to the conclusion about oxygen loss through grain boundaries in films with nanocrystallites of 2-10 nm in size, and also through structural defects in films with larger crystallites.

This paper presents a detailed study of the hysteresis properties of film structures based on bilayers of the (Cr-Mn)/Fe type. The temperature dependences of several parameters of the hysteresis loops of the Fe layers are determined for films varying in the composition and thickness of the Cr-Mn layer, as well as in the structure of buffer coatings. The compositional and temperature intervals of the existence of the antiferromagnetic ordering in the Cr-Mn layer and the related features of the temperature changes in the coercive force, its anisotropy in the plane of the films and the exchange bias field are established. The causal analysis of the established regularities is performed.
Patient Safety of Perioperative Medication Through the Lens of Digital Health and Artificial Intelligence
Authors: Ye Jiancheng
Published: May 2023

Perioperative medication has made significant contributions to enhancing patient safety. Nevertheless, administering medication during this period still poses considerable safety concerns, with many errors being detected only after causing significant physiological disturbances. The intricacy of medication administration in the perioperative setting poses specific challenges to patient safety. To address these challenges, implementing potential strategies and interventions is critical. One such strategy is raising awareness and revising educational curricula regarding drug safety in the operating room. Another crucial strategy is recognizing the importance of redundancy and multiple checks in the operating room as a hallmark of medication safety, which is not a common practice. Digital health technologies and artificial intelligence (AI) also offer the potential to improve perioperative medication safety. Computerized physician order entry systems, electronic medication administration records, and barcode medication administration systems have been proven to reduce medication errors and improve patient safety. By implementing these strategies and interventions, health care professionals can enhance the safety of perioperative medication administration and improve patient outcomes.
Exploring the spread and impact of health-related misinformation on Chinese and English social media during the COVID-19 pandemic: a comparative bibliometric study (Preprint)
Authors: He Yunfan , Liang Jun , Fu Wenguang , Liu Yongcheng , Yang Fangyu , Ding Shunjing , Lei Jianbo
Published: May 2023

BACKGROUND

Online health-related misinformation poses a serious threat to public health. As the coronavirus disease 2019 (COVID-19) pandemic aggravated the spread of misinformation, relevant research has surged.

OBJECTIVE

To systematically summarize Chinese and English articles regarding health-related misinformation on social media during the COVID-19 pandemic and quantitatively describe research progress.

METHODS

Using bibliometrics, we systematically analyzed and compared the characteristics of scientific articles in English and Chinese regarding article numbers, journals, authors, countries, institutions, funding, and research topics and compared changes in hot topics.

RESULTS

This study included 1,241 articles. Article numbers and citations surged during the COVID-19 pandemic (1.80 times and 2.94 times, respectively, compared to pre-pandemic data), but high-impact articles were lacking. The field lacked a core group of authors and collaborative networks. China was the country with the largest number of papers (n=265) and funds (n=284), but articles in English exceeded by far those in Chinese (1,078 vs. 163, respectively). Regarding article topics before and after the COVID-19 pandemic, the transformation from qualitative small-data analyses to quantitative empirical big-data research has been realized.

CONCLUSIONS

With the maturity of natural language processing technology, in-depth mining of massive user-generated content has become a hot spot. The outbreak of the COVID-19 pandemic has prompted the research focus to shift from misinformation-related health problems to social problems involving the sources, content, channels, audiences, and effects of communication networks. Using artificial intelligence technology like machine learning to deeply mine large amounts of user-generated content on social media will be a future research hot spot.
Associations between Net Gastrointestinal Alkali Absorption, 24-Hour Urine Lithogenic Factors, and Kidney Stones
Authors: Ferraro Pietro Manuel , Taylor Eric N. , Asplin John R. , Curhan Gary C.
Published: May 2023

Background

It is not clear whether kidney stone formers have an abnormal handling of alkali and acid precursors in the gut, which might affect urine composition and ultimately stone formation. In this study, we aimed to investigate the determinants of net gastrointestinal alkali absorption and its associations with key urinary parameters in a large group of stone formers and non–stone formers.

Methods

Data were collected from three independent cohorts with at least one 24-hour urine collection. We explored potential determinants of net gastrointestinal alkali absorption and the association between net gastrointestinal alkali absorption, urinary parameters, and stone former status. Finally, we estimated the proportion of the association between urine parameters and stone former status explained by differences in net gastrointestinal alkali absorption.

Results

The analysis included 6067 participants (1102 men and 4965 women; 698 and 1804 of whom were stone formers, respectively). Average net gastrointestinal alkali absorption values were consistently lower in stone formers across the three cohorts (from −15.0 to −4.9 mEq/d). Age was directly associated with net gastrointestinal alkali absorption, whereas body mass index and net endogenous acid production were inversely associated. Net gastrointestinal alkali absorption was inversely associated with supersaturation for calcium oxalate, uric acid, and renal net acid excretion and directly associated with supersaturation for calcium phosphate, urine pH, and citrate. The odds of being a stone former was 15% (13%–17%) lower per 10 mEq/24 hours higher net gastrointestinal alkali absorption. Differences in net gastrointestinal alkali absorption explained a modest amount of the differences between stone formers and non–stone formers for supersaturation for calcium oxalate (6.3%) and a sizable amount for supersaturation for uric acid (15.2%), urine pH (38.3%), citrate (26.2%), and renal net acid excretion (63.4%).

Conclusions

Kidney stone formers have lower net gastrointestinal alkali absorption, and this explains differences in urine composition and the likelihood of stone formation.

Published: May 2023

Background

Uromodulin is a protein made only by the kidney and released in urine, circulating in polymerizing and nonpolymerizing forms. This protein's multiple functions include inhibition of stone formation in the urine. The physiological determinants of uromodulin production are incompletely understood.

Methods

We investigated changes in uromodulin levels and key factors governing its production and release in urine and serum. We performed an experiment to determine whether water loading, a common intervention to prevent stone formation, will alter the rate of uromodulin production. During a 2-day period, 17 stone forming participants and 14 control participants were subjected to water loading (day 1) and normal fluid intake (day 2). Uromodulin levels were measured on timed hourly collections in urine and plasma during the period of the study.

Results

Water loading increased urinary uromodulin secretion (33±4 versus 10±4 μg/min at baseline, P < 0.0001) in stone formers and control participants. Despite high urine volumes, most participants maintained relatively stable urinary uromodulin concentrations. Native Western blots for polymerizing and nonpolymerizing uromodulin suggest that polymerizing uromodulin was the predominant form at higher urinary flow volumes. Urine flow rates and sodium excretion were significant correlates of urinary uromodulin production. Water loading did not affect serum uromodulin levels, which were also not associated with urinary uromodulin.

Conclusions

Water loading increases the secretion of polymerizing urinary uromodulin. This increased secretion reduces the variability of urinary uromodulin concentrations despite high urine volumes. Serum uromodulin levels were not affected by this treatment.
Rip Van Winkle: el héroe improductivo
Authors: Garduño Moreno Juan Gabriel , Gómez-Pezuela Reyes María del Carmen
Published: May 2023

A doscientos años de la publicación de la obra de Washington Irving, Rip Van Winkle (1820), la caracterización del protagonista que más ha prevalecido es la de un individuo perezoso, despreocupado e improductivo. A lo largo de la obra, el personaje es retratado como alguien que muestra poco interés en ocuparse en algún trabajo que le proporcione beneficios económicos. Presionado por las expectativas de la sociedad que lo conminan a conducirse como un “buen marido”, Van Winkle elude sus obligaciones domésticas y opta por vagabundear en una montaña cercana. En este artículo se propone una lectura del relato a la luz de algunas claves del pensamiento del filósofo Byung-Chul Han, concretamente las concernientes al concepto de vita contemplativa, cuya exposición se desglosa en El aroma del tiempo (2015) y La sociedad del cansancio (2017). El análisis ilumina una faceta distinta del personaje y lo muestra como un hombre sensible, inclinado a adentrarse en un estado contemplativo. Se concluye que la actitud de Van Winkle hacia la vida expresa un rechazo ante la inevitable llegada del progreso y simboliza la inefable permanencia de un mundo que se resiste a cambiar ante la inminente urbanización provocada por la industrialización. En tal sentido, su conducta representa una dura crítica hacia el imperativo de la productividad dentro del contexto de la sociedad norteamericana de principios del siglo diecinueve.

This study isolated and identified Bacillus amyloliquefaciens B1 from Carcinoscorpius rotundicauda by carrying out the 16S rRNA sequence analysis, reconstructing the phylogenetic tree based on the Environment for Tree Exploration (ETE3) v3.1.1 belonging to the GenomeNet. By an indirect competitive enzyme-labeled immunoassay, B1 could produce tetrodotoxin (TTX) in MRS was more highly than LB media. After purification, TTX producing ability in B1 could be detected in ELISA assay, high performance liquid chromatography (HPLC). The gel permeation chromatography and gas chromatography were applied to determine the molecular weight of EPS and the concentration of glucose in EPS. The results indicated the highest molecular weight of exopolysaccharides (EPS) estimated 1.33 × 106 Da consisted of glucose (150.09 µg/g). TTX yield was proportional to EPS production in the bacterium. The antimicrobial activities of EPS were determined by agar well diffusion method. Diameter of inhibition zone (mm) of Bacillus amyloliquefaciens EPS on the test microorganisms. The EPS could inhibit against Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa ATCC 27853, Escherichia coli ATCC 25922, Vibrio parahaemolyticus ATCC 17802 and Micrococcus luteus ATCC 10240. In silico prediction, TTX might interact with Bacillus amyloliquefaciens via the extracellular domain of noncanonic ABC-type transporter from gram positive bacteria. TTX might also interact with peptidase S54, mistic, metal binding protein of Bacillus subtilis and tryptophan-rich sensory protein of Bacillus cereus. This study provides the understanding of TTX producing Bacillus amyloliquefaciens B1 isolated from Carcinoscorpius rotundicauda.

Pluronic F-127 (PF-127) hydrogel is a versatile biomaterial with promising applications in drug delivery, tissue engineering, and regenerative medicine. PF-127 has antiadhesive activity that prevents bacterial adhesion by creating a hydrated layer on the bacterial surface. This property makes PF-127 suitable for preventing implant-associated infections. In this study, we aimed to evaluate the antibacterial properties of PF-127 using field isolates of Staphylococcus aureus (Gram-positive bacteria) and Escherichia coli (Gram-negative bacteria) and compare them with different antibiotic standards. The antimicrobial potential was assessed using disk diffusion assays with four standard concentrations (20%, 25%, 30%, and 40%). The test microorganisms were inoculated on agar plates, and sterile filter paper disks infused with PF-127 hydrogels were placed alongside standard antibiotic disks. After incubation, the inhibition zones were measured to determine antimicrobial activity. Our results showed that PF-127 lacked intrinsic antimicrobial activity against S. aureus and E. coli at the tested concentrations. In conclusion, PF-127 hydrogel is a promising neutral carrier hydrogel system for loading antibiotics and antimicrobial compounds. Its unique properties, such as biocompatibility and thermo-responsive behaviour, combined with its antiadhesive activity, make it an ideal candidate for various biomedical applications.

Published: May 2023

Suicide is the last stage of depression, and antidepressants (ATDs) are drugs created with the aim of preventing the disease from advancing to more critical stages. However, in 2004, a study conducted by the Food and Drug Administration (FDA) found an association between the use of ATDs and increased risks of suicidal behavior/ideation in users. Thus, several studies were carried out to find out whether this statement is still plausible, as new antidepressants were created during this period and, in addition, ATDs are still the gold standard treatment in the most severe forms of depression, in this sense, the analysis of its risk-benefit is of fundamental importance. This study is an integrative literature review, described from 2012 to 2022, using the following databases: PubMed and VHL. The objective of the research was to describe whether the use of antidepressants is associated with a higher risk of suicide in patients. Among the results found in the analysis of 23 articles, 5 drugs were found that were related to a greater probability of developing suicidal behavior/ideation. However, venlafaxine showed a connection with self-cide much better than the others, and in a qualitative sense, it was the drug with the most evidence. Therefore, the study was not so conclusive due to difficulties in analyzing secondary data. Most of the data collected require greater methodological rigor, moreover, none of the surveys covered a difference between population groups, other than age, showing low variety in the studies.

Entanglement entropy production in Quantum Neural Networks
Authors: Ballarin Marco , Mangini Stefano , Montangero Simone , Macchiavello Chiara , Mengoni Riccardo
Published: May 2023

Quantum Neural Networks (QNN) are considered a candidate for achieving quantum advantage in the Noisy Intermediate Scale Quantum computer (NISQ) era. Several QNN architectures have been proposed and successfully tested on benchmark datasets for machine learning. However, quantitative studies of the QNN-generated entanglement have been investigated only for up to few qubits. Tensor network methods allow to emulate quantum circuits with a large number of qubits in a wide variety of scenarios. Here, we employ matrix product states to characterize recently studied QNN architectures with random parameters up to fifty qubits showing that their entanglement, measured in terms of entanglement entropy between qubits, tends to that of Haar distributed random states as the depth of the QNN is increased. We certify the randomness of the quantum states also by measuring the expressibility of the circuits, as well as using tools from random matrix theory. We show a universal behavior for the rate at which entanglement is created in any given QNN architecture, and consequently introduce a new measure to characterize the entanglement production in QNNs: the entangling speed. Our results characterise the entanglement properties of quantum neural networks, and provides new evidence of the rate at which these approximate random unitaries.
Linear optics and photodetection achieve near-optimal unambiguous coherent state discrimination
Authors: Sidhu Jasminder S. , Bullock Michael S. , Guha Saikat , Lupo Cosmo
Published: May 2023

Coherent states of the quantum electromagnetic field, the quantum description of ideal laser light, are prime candidates as information carriers for optical communications. A large body of literature exists on their quantum-limited estimation and discrimination. However, very little is known about the practical realizations of receivers for unambiguous state discrimination (USD) of coherent states. Here we fill this gap and outline a theory of USD with receivers that are allowed to employ: passive multimode linear optics, phase-space displacements, auxiliary vacuum modes, and on-off photon detection. Our results indicate that, in some regimes, these currently-available optical components are typically sufficient to achieve near-optimal unambiguous discrimination of multiple, multimode coherent states.

Authors: Alfonso Santiesteban Daniel , Abreu Blaya Ricardo , Árciga Alejandre Martín Patricio
Published: May 2023

This research is devoted to a fundamental system of equations in Linear Elasticity Theory: the Lamé-Navier system. The Clifford algebras language allows us to rewrite this system in terms of the Euclidean Dirac operator, which at the same time suggests a very natural generalization involving the so-called structural sets. We are interested in finding some structures in the solutions of these generalized Lamé-Navier systems. The flexibility involved in the consideration of arbitrary structural sets suggests that this system leads to a wide range of systems of partial differential equations that could be of mathematical interest as well as in the context of Physics.

Tibetan pigs are a locally bred domestic pig breed originating from the
Tibetan Plateau in China. They can be categorized into four distinct
groups based on their geographical locations: Sichuan Tibetan pigs,
Tibetan pigs from Tibet, Yunnan Tibetan pigs, and Gansu Tibetan pigs.
This study aimed to explore population diversity, genetic structure and
selection signals among Tibetan pigs in four Chinese national nature
reserves. The results show that there is different observed
heterozygosity among Tibetan pig populations (0.1957-0.1978). Ratio of
runs of homozygosity (Froh) calculation of four Tibetan pig populations
by runs of homozygosity (ROH) revealed the presence of inbreeding within
the population (0.0336-0.0378). Analysis of the genetic structure
demonstrated distinct population stratification among the four Tibetan
pig populations, with each showing relatively independent evolutionary
directions. Furthermore, the selection signals predominantly involved
processes such as DNA repair, immune regulation, muscle fat deposition,
and adaptation to hypoxia. In conclusion, this study enhances our
understanding of the genetic characteristics of Tibetan pig populations
and provides a theoretical reference for the conservation of resources
across different populations of Tibetan pigs.
Skill versus inequality
Authors: Arda Özalp Leyla , Özalp Hüseyin
Published: May 2023

This paper explores empirical evidence for a connection between income inequality and skill (advanced-level educated workers share) using panel data methods that take into account cross-section dependency and heterogeneity. To assess the income inequality associated with skill, we run a data set for 24 developed the Organisation for Economic Co-operation and Development (OECD) countries from 1995 to 2018. In order to determine the stationary characteristics of the variables, we employ the Cross-Sectionally Augmented Im, Pesaran and Shin (CIPS) test approach. Following this, we employ Westerlund (2007), and Gengenbach, Urbain, and Westerlund (2016) Panel Cointegration tests, and then the Panel Dynamic Ordinary Least Squares (PDOLS) estimator. Our empirical test results conclude that there is a relationship between inequality and skill in the long-run and the PDOLS estimator findings show that as the skill level in employment increases, inequality decreases. In addition, according to the findings, this negative relationship is more pronounced in the United States, whereas it is more moderate or not valid in European countries. The results obtained are primarily consistent with the framework presented by Acemoglu (2002, 2003). These findings constitute one of the main contributions of the study in terms of supporting Acemoglu?s (2003) thesis that the skill premium is more pronounced in the United States.

Published: May 2023

Improved β-cell function seems to be essential for better glucose homeostasis after Roux-en-Y gastric bypass but is less studied after sleeve gastrectomy (SG). We evaluated the effects of SG on β-cell function in obese patients with diabetes (DM group) and without (Control group) in response to both oral and intravenous glucose stimulation. The DM group demonstrated impaired insulin sensitivity and insulin response to glucose before surgery. The insulin sensitivity index of both groups significantly improved after SG. In addition, the insulin response to glucose (early insulinogenic index in OGTT and AIRglu in IVGTT) increased in the DM group but decreased in the Control group. As a result, β-cell function improved significantly in both groups after SG since the disposition index (DI) increased in both. However, the DI of DM group still can’t restore to the level of Control group up to 1 year after SG. Our results support that both obese patients with and without diabetes could benefit from SG in β-cell function. For obese patients at risk of or have been diagnosed with diabetes, interventions should be recommended early to preserve or restore β-cell function, and SG could be an effective choice. Further studies are needed for long-term effects.
Chinese and Javanese Traders in the Frame of Social Relations
Authors: Nihayah Hamhij Durroh
Published: May 2023

The purpose of this study is to explain the social relations of Chinese and Javanese ethnic traders in traditional markets. The research was conducted in Kangkung Market, Bumi Waras District, Bandar Lampung City. Social relations between Chinese and Javanese ethnic traders in the Kangkung market are reflected in several activities carried out, namely social relations in the market and outside the market. Relations outside the market still show the social distance that is more influenced by ethnicity, but relations in the market seem closer. Service to customers does not care about ethnic differences. In general, Javanese and Chinese can coexist well, both benefitting from each other socially and economically. However, ethnic differences between the two still exist and develop in the community which is enough to affect the social relations of the two ethnicities in daily life.
The Environmental Policy of the USA in the Framework of the Kyoto Protocol and Paris Climate Agreement Before Biden's Administration
Authors: Ayvaz Zehra , Ramadhan Jelang
Published: May 2023

Despite different kinds of “habitat” research (Moon, Mars, etc.) has accelerated, the Earth is still actually the only habitat for living creatures. However, due to developments in the last century, our world has faced various environmental problems and dangers like climate change. So, countries carry out national and international efforts to minimize and prevent these hazards. One of the countries that researches these problems is the United States. The fact that the United States, the most powerful actor in the international system, has not shown sufficient interest in environmental and climate change issues and that US domestic policy has largely had an impact on these issues, contributed to preparing this study. The paper used qualitative research design by emphasizing literature study and a descriptive method to measure the trend in perceiving climate change from the perspective of the US policy. So, in this study, the US Environmental Policy will be discussed in the context of the Kyoto Protocol and the Paris Agreement before Biden's Administration which resulted in Washington cannot take a clear stance on environmental and climate issues due to dilemmas in leadership change and domestic politics.

The number of retail pharmacies in Balingasag, Misamis Oriental have increased due to the promising economic development of the municipality. Despite customers having wide alternative options to choose, service quality-implementation by respective pharmacies have perhaps executed inconsistently leading to a poor outlook of the stores service. The main objective of this study is to assess the service quality and performance efficiency of pharmacies surrounding the central area of the municipality of Balingasag using Analytical Hierarchy Process (AHP).  We discuss in this paper the analysis of criterion prioritization through expert judgments, identify retail pharmacies with high and low performance efficiency of service quality. Criteria considered in formulating the AHP architecture is based on the retail service quality scale of Dabholkar et al. (1996) including workplace hygiene, understanding, accessibility, reliability, guidance, policy, and problem – solving. Based on experts’ judgments using pairwise comparison, different performance indicators have been evaluated: the most prioritized criterion among the seven (7) criteria is ‘problem-solving’ with a criterion weight of 0.22 while the least prioritized criterion is ‘accessibility’ with a criterion weight of 0.05. Empirical evaluation integrated with the obtained criterion weights showed that among ten (10) retail pharmacies; nine (9) pharmacies have good performance quality, while the remaining pharmacy have an acceptable performance in service quality implementation. The result of this study gives emphasis that ‘problem-solving’ criterion in the implementation of service quality should be strengthened by retail pharmacies to subsequently improve its service quality performance and competitive positioning.
