Modeling Long-Term Creep and Physical Aging Behavior of Carbon/Epoxy Composites Based on Coupling Model
Authors: Yang Jiangyan , Ma Xiaofei , Wang Hui , Shang Fulin , Hou Demen
Published: January 2024

Our previous study observed a non-monotonic time-dependent deformation from the long-term isothermal tensile creep tests, indicating the significant influence of physical aging on viscoelastic behavior. In this work, a new physical mechanism-based thermo-rheological complex constitutive relation that combines Ngai’s coupling model and Schapery’s nonlinear viscoelastic framework is established. A piecewise function was used to represent the non-monotonic time-varying compliance, in which molecular cooperativity and the interaction between different relaxing units were considered. The strength of the interaction is presented by a coupling strength parameter. The effects of stress and temperature on the deformation are represented by not only two shift factors but also are associated with the coupling strength parameter, which is modeled as a function of the fictive temperature. The physical aging effect is also incorporated into the evolution of the fictive temperature. The proposed model was verified by a comparison of the experimental and finite element simulated results. Finally, the physical meanings of the model parameters and their correlation with the macroscopic deformation of the laminates were discussed.
Series NESs for Suppressing Strongly Forced Vibration
Authors: Du Ting-Kai , Ding Hu , Zhang Dong-Sheng , Chen Li-Qun
Published: January 2024

Improving the ability of nonlinear energy sink (NES) to suppress large vibrations under strong excitation has been widely concerned. Moreover, distributing NES to suppress multimodal resonances is also an issue that deserves more attention. This paper investigates the distribution strategy of the series NES in suppressing the vibration of a two-degree-of-freedom (2-DOF) system. Dynamic models are developed for two strategies: centralized and distributed series NES. The vibration reduction efficiency of these strategies is compared, and the approximate results obtained from the analytical analysis were verified using numerical methods. The research results indicate that distributing the series NES among different vibration sources can lead to improved vibration reduction performance. Moreover, the distributed vibration reduction strategy exhibits greater adaptability to different modes of primary system. Furthermore, while keeping the total additional weight of the NES unchanged, the effects of the series NES and 1DOF NES on vibration control were compared. The results demonstrate that, under large amplitude excitation, the series NES has a better vibration reduction effect than the 1DOF NES when using distributed NES to control the vibration of a 2-DOF system. Additionally, by studying the energy transfer between NES oscillators in series, the series NES with high stiffness asymmetry exhibits superior vibration reduction. The findings of this study contribute to the advancement of research on the NES control of strong excitation vibration and multi-mode structure vibration.

A simpler proof of Sternfeld’s Theorem
Authors: Dzhenzher S.
Published: January 2024

In Sternfeld’s work on Kolmogorov’s Superposition Theorem appeared the combinatorial–geometric notion of a basic set and a certain kind of arrays. A subset [Formula: see text] is basic if any continuous function [Formula: see text] could be represented as the sum of compositions of continuous functions [Formula: see text] and projections to the coordinate axes.

The definition of a Sternfeld array is presented in this paper.

Sternfeld’s Arrays Theorem. If a closed bounded subset[Formula: see text] contains Sternfeld arrays of arbitrary large size then[Formula: see text] is not basic.

The paper provides a simpler proof of this theorem.
Ontology Knowledge Map Approach Towards Building Linked Data for Vietnamese Legal Applications
Authors: Ngo Hung Q. , Nguyen Hien D. , Le-Khac Nhien-An
Published: January 2024

Today, every aspect of society’s activities is regulated by laws from the national and local levels. The increasing number of legal documents interwoven with each other also leads to difficulties in searching and applying in practice. In addition, later legal documents may change or invalidate previous legal documents. The construction of knowledge maps that involve one or a group of legal documents is an effective approach to represent actual knowledge domains. A legal knowledge graph constructed from laws and legal documents can enable a number of applications, such as question answering, document similarity, legal search, legal information retrieval, and legal argument claims. In this paper, we describe an ontology-based knowledge map approach for building a Vietnamese legal linked data from the source of about 325,000 legal documents. This study includes an integrated ontology to represent the legal knowledge from legal documents. This model integrates the ontology of relational knowledge and the graph of entities in the form of a concept graph. It can express the semantics of the content of a given legal document. In addition, this study also addresses potential legal applications, which can use the built linked data as a foundation resource of legal. We also highlight open challenges in the realization of knowledge graphs in a technical legal system that enables this approach at scale.
Correlation between the Total Dose of Follicle-Stimulating Hormone and Cumulative Live Birth Rate in Women Undergoing in Vitro Fertilization
Authors: Le Long Ho , Ho Ngoc Anh Vu , Duong Toan , Ho Manh Tuong , Vuong Ngoc Lan
Published: January 2024

Background: Follicle-stimulating hormone (FSH) is widely used during assisted reproductive therapy to facilitate the development of multiple follicles. In turn, the number of oocytes retrieved has been shown to relate to the live birth rate. This retrospective study investigated the correlation between the total FSH dose used and the cumulative live birth rate in individuals who had undergone in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI).

Methods: This retrospective study included women undergoing IVF/ICSI using a gonadotropin-releasing hormone antagonist protocol who had a regular menstrual cycle and an expected normal response to ovarian stimulation. Cumulative live birth rate was defined as the first live birth following the use of all fresh and frozen transfers of embryos derived from one stimulated IVF/ICSI cycle.

Results: The analysis included 7,130 stimulated cycles in 6,517 individuals (9,138 transfers). The mean age, antral follicle count, and anti-Müllerian hormone level were [Formula: see text], [Formula: see text], and [Formula: see text][Formula: see text]ng/ml, respectively. The mean total FSH dose, total number of oocytes retrieved, and total FSH dose per oocyte retrieved were [Formula: see text] IU, [Formula: see text], and [Formula: see text] IU, respectively. There was a significant negative correlation between the total FSH dosage and the cumulative live birth rate in women aged [Formula: see text] years ([Formula: see text], 95% confidence interval [−0.14, −0.08]; [Formula: see text]) and in those aged [Formula: see text] years ([Formula: see text], 95% confidence interval [−0.11, −0.02]; [Formula: see text]).

Conclusions: The cumulative live birth rate decreased as the total FSH dose increased. These findings suggest that physicians may wish to avoid prescribing a high dose of FSH in women undergoing IVF/ICSI who are predicted not to have a poor response.

Authors: Zhou Bowen , Ding Ning
Published: January 2024

Large Language Models (LLMs), exemplified by GPT-4, have transcended traditional boundaries in language processing, demonstrating remarkable capabilities in understanding and generating nuanced text. Crucially, these models are pioneering a paradigm shift in Artificial Intelligence (AI) applications — from solving narrowly defined problems to navigating complex, real-world scenarios. Such a shift is based on a simple and fundamental principle: LLMs can process any data that can be serialized and tokenized, enabling them to engage in multifaceted reasoning and utilize diverse tools. This capability positions LLMs to operate effectively in broader, more intricate contexts, marking a leap in AI’s practical applicability and potential.

Published: January 2024

Cloud computing is an on-demand availability of computing resources. The current cloud computing environment uses different algorithms for its security; RC4 is one of them. However, due to the serial implementation of RC4 over cloud computing, the process of encryption and data transmission is badly affected by the factors of poor latency. This research is proposed to cover this factor by implementing a parallel RC4 algorithm in a cloud computing environment. The parallel RC4 model has been developed in web-based architecture relevant to the cloud computing environment. The method processed data simultaneously in four parallel pipelines encrypted through the RC4 algorithm. The proposed method used RC4 algorithms’ parallel implementation to encrypt and decrypt the data. The proposed method increases the efficiency of data encryption and decryption and transmission over a cloud environment using four pipelines at once. These four pipelines receive data and encrypt them using a key and then merge those four streams into a single cipher. These four pipelines enhance the speed of communication over cloud and solve the latency issue majorly. Data sending from node devices to cloud servers is divided into four equal streams and then encrypted using RC4 distinctly but parallel. Then after the roaming, the data are again first combined and then decrypted using the RC4 algorithm. The sample data sets are evaluated on the criteria of the starting time and ending time of the encryption and decryption of data. Results show that the proposed method is able to enhance the speed of the whole process up to average 3.7% due to the implementation of parallel technique and had reduced the time notably. The future work on this research involves enhancement of security process of RC4 algorithm since it can be breached easily.

Authors: Yao Jianping , Tran Son N. , Garg Saurabh , Sawyer Samantha
Published: January 2024

Deep learning (DL) plays an important role in modern agriculture, especially in plant pathology using leaf images where convolutional neural networks (CNN) are attracting a lot of attention. While numerous reviews have explored the applications of DL within this research domain, there remains a notable absence of an empirical study to offer insightful comparisons due to the employment of varied datasets in the evaluation. Furthermore, a majority of these approaches tend to address the problem as a singular prediction task, overlooking the multifaceted nature of predicting various aspects of plant species and disease types. Lastly, there is an evident need for a more profound consideration of the semantic relationships that underlie plant species and disease types. In this article, we start our study by surveying current DL approaches for plant identification and disease classification. We categorise the approaches into multi-model, multi-label, multi-output, and multi-task, in which different backbone CNNs can be employed. Furthermore, based on the survey of existing approaches in plant pathology and the study of available approaches in machine learning, we propose a new model named Generalised Stacking Multi-output CNN (GSMo-CNN). To investigate the effectiveness of different backbone CNNs and learning approaches, we conduct an intensive experiment on three benchmark datasets Plant Village, Plant Leaves, and PlantDoc. The experimental results demonstrate that InceptionV3 can be a good choice for a backbone CNN as its performance is better than AlexNet, VGG16, ResNet101, EfficientNet, MobileNet, and a custom CNN developed by us. Interestingly, there is empirical evidence to support the hypothesis that using a single model for both tasks can be comparable or better than using two models, one for each task. Finally, we show that the proposed GSMo-CNN achieves state-of-the-art performance on three benchmark datasets.
Intent-Oriented Dynamic Interest Modeling for Personalized Web Search
Authors: Bai Yutong , Zhou Yujia , Dou Zhicheng , Wen Ji-Rong
Published: January 2024

Given a user, a personalized search model relies on her historical behaviors, such as issued queries and their clicked documents, to generate an interest profile and personalize search results accordingly. In interest profiling, most existing personalized search approaches use “static” document representations as the inputs, which do not change with the current search. However, a document is usually long and contains multiple pieces of information, a static fix-length document vector is usually insufficient to represent the important information related to the original query or the current query, and makes the profile noisy and ambiguous. To tackle this problem, we propose building dynamic and intent-oriented document representations which highlight important parts of a document rather than simply encode the entire text. Specifically, we divide each document into multiple passages, and then separately use the original query and the current query to interact with the passages. Thereafter we generate two “dynamic” document representations containing the key information around the historical and the current user intent, respectively. We then profile interest by capturing the interactions between these document representations, the historical queries, and the current query. Experimental results on a real-world search log dataset demonstrate that our model significantly outperforms state-of-the-art personalization methods.

A Mg-In Alloy Interphase for Mg Dendrite Suppression
Authors: Lee Brian C. , See Kimberly A.
Published: January 2024

Mg metal batteries have attracted much attention as an alternative to Li-ion technology due to the high abundance and volumetric capacity of Mg metal. Further, early reports show that Mg is less prone to dendritic growth compared to Li, thereby improving the safety and long-term reversibility of Mg metal anodes. However, dendritic growth of Mg can be observed in various conditions, causing cell shorting and capacity loss. Herein, we report a chemically-formed Mg-In alloy interphase that suppresses nonuniform Mg growth during electrochemical reduction. Ex-situ X-ray diffraction shows that upon reduction, Mg alloys into the Mg-In interphase with no evidence of Mg deposition on top of the surface during initial cycles. Interestingly, further reduction results in Mg depositing underneath the interphase, which confirms Mg mobility through the interphase. However, the alloying reaction is kinetically limited, leading to significant Mg deposition on top of the interphase at high current densities. Thus, alloys on Mg can affect deposition morphologies, but are limited by the kinetics of Mg conduction through the alloy.

The performance of sodium-ion batteries critically depends on the cathode materials used, making it essential to explore and optimize suitable candidates. Among them, O3-structured NaNi0.33Fe0.33Mn0.33O2 has emerged as one of the most promising cathode materials due to its outstanding electrochemical properties. However, there still exists a knowledge gap regarding the detailed synthesis conditions and the comprehensive performance of the full cell using this material. In this study, we investigated the influence of synthesis temperature, time, and sodium content on the electrochemical performance and charge-discharge kinetics of O3-structured NaNi0.33Fe0.33Mn0.33O2, prepared via the PVP-gel combustion method. Through systematic analysis, we elucidated the impact of these synthesis parameters on the material’s properties and battery performance. The results revealed that the optimized conditions led to a cathode material with superior electrochemical performance, exhibiting enhanced capacity with 139 mAh g−1 at 0.1 C and 96 mAh g−1 at 10 C. Additionally, a full cell using the optimized cathode material was studied, showing promising performance. This research sheds light on the significance of synthesis parameters in tailoring the electrochemical properties of O3-structured NaNi0.33Fe0.33Mn0.33O2 for sodium-ion batteries. The insights gained from this study hold valuable implications for the further development of practical sodium-ion battery cathode materials.

Authors: Naskar Pappu , Saha Ankita , Biswas Biplab , Banerjee Anjan
Published: January 2024

This review depicts the various designs of different current collectors for rechargeable batteries, which are either commercially available or have commercial prospects. The functions of current collectors are vividly discussed along with the fundamental properties, i.e., good electrical conductivity and chemical cum electrochemical stabilities under the battery operating window. Based on the required properties, metal or alloy substrates have the best credentials for suitable current collectors; but the anodic corrosion is a bottleneck for them. Therefore, non-metallic current collectors, mainly graphitic substances, could be envisaged, which have low mechanical strength and high cost. Hence, the low cost and robust metallic current collectors with corrosion-protective modifications would be the mostly acceptable. Herein, we elaborate state-of-the-art design and development strategies of current collectors for (i) lead acid batteries, (ii) alkaline batteries, (iii) Li-ion batteries, (iv) Li-metal batteries, (v) Li-sulphur batteries, (vi) metal ion batteries beyond the Li-ion chemistry, (vi) flow batteries and (vii) metal-air batteries. Relative to the electrode active materials and electrolytes, the research and developments (R&D) on current collectors are truly limited. However, to keep the available know-how on current collector technology under a single umbrella, we demonstrate a holistic view that essentially covers the entire spectrum of today’s rechargeable battery market.

Authors: Priyanka  , Bansal Sonia , Kaur Preet
Published: January 2024

Moisture Content determination inside the grains is essential for grain processing activities including harvesting, storing, inspecting, and transporting. In this paper, microstrip and metamaterial embedded patch sensors were developed to determine the moisture content and mean relative error (MRE) of rice, wheat, and pulse. The sensors were simulated in HFSS, prototypes were fabricated and the measurement was done using VNA and anechoic chamber. The Microstrip sensor was operating at a frequency of 5.2 GHz and the metamaterial-embedded sensor was operating at 4.5 GHz. Calibration equations were obtained by using the values of reflection coefficients and moisture content ranging from 11.76% to 25%. For analyzing the efficacy of designed sensors, predicted moisture content (PMC) and actual moisture content (AMC) have been compared and the lowest mean relative error has been determined. The analysis shows that the metamaterial embedded sensor has better sensitivity and accuracy than the microstrip sensor. The lowest mean relative error in moisture prediction for metamaterial sensor was 1.07% for rice, 1.13% for wheat, and 1.47% for pulse respectively. A comparison of the proposed metamaterial embedded sensor with earlier designed sensor in literature was also presented in this work and it was found that the proposed sensor had more accuracy and sensitivity than earlier designs.

Published: January 2024

This study conducted in-depth research on the limitation problem of mass transfer of gas molecules on the surface of the photoelectrode to the efficiency of photoelectrochemical water splitting. Experimental results reveal significant differences in the dynamic characteristics of bubbles and mass transfer mechanisms during bubble growth under different pH conditions. As the pH deviates from 7.0 (vs RHE), the reaction rate increases, the bubble nucleation voltage decreases, and the terminal rising velocity increases significantly. During the rapid growth phase of bubbles, the mass transfer coefficient reaches its peak, accounting for only 1% of the entire evolution cycle. In a neutral environment (pH = 7.0), the transient mass transfer coefficient reaches a maximum at approximately 1 s of bubble growth, while in an alkaline environment (pH = 12.0), it reaches a maximum at around 0.1 s. In strongly alkaline environments (pH = 13.0), the PEC reaction rate and mass transfer rate increase, resulting in the highest gas production efficiency. The mass transfer coefficients were improved by about 72.4% and 42.8% (vs Ag/AgCl) and by about 22.2% and 33.3% (vs RHE) in the strong alkaline environment relative to the strong acid environment (pH = 1.0) and the neutral environment, respectively.
Immunohistochemical and ultrastructural characterization of the inner ear epithelial cells of splitnose rockfish (Sebastes diploproa)
Authors: Kwan Garfield T. , Andrade Leonardo R. , Prime Kaelan J. , Tresguerres Martin
Published: January 2024

The inner ear of teleost fish regulates the ionic and acid-base chemistry and secretes protein matrix into the endolymph to facilitate otolith biomineralization, which is used to maintain vestibular and auditory functions. The otolith is biomineralized in a concentric ring pattern corresponding to seasonal growth, and this calcium carbonate (CaCO3) polycrystal has become a vital aging and life-history tool for fishery managers, ecologists, and conservation biologists. Moreover, biomineralization patterns are sensitive to environmental variability including climate change, thereby threatening the accuracy and relevance of otolith-reliant toolkits. However, the cellular biology of the inner ear is poorly characterized, which is a hurdle for a mechanistic understanding of the underlying processes. This study provides a systematic characterization of the cell types in the inner ear of splitnose rockfish ( Sebastes diploproa). Scanning electron microscopy revealed the apical morphologies of six inner ear cell types. In addition, immunostaining and confocal microscopy characterized the expression and subcellular localization of the proteins Na+-K+-ATPase, carbonic anhydrase, V-type H+-ATPase, Na+-K+-2Cl−-cotransporter, otolith matrix protein 1, and otolin-1 in six inner ear cell types bordering the endolymph. This fundamental cytological characterization of the rockfish inner ear epithelium illustrates the intricate physiological processes involved in otolith biomineralization and highlights how greater mechanistic understanding is necessary to predict their multistressor responses to future climate change.

Published: January 2024

Unauthorized access to hazardous substances poses a serious threat to public health. Typically, these substances, such as chemicals, are housed within warehouses or laboratory facilities, making strict control over any unauthorized entry. The control can be achieved through various measures, including access control systems, registration systems, remote inspection and surveillance, and personnel checks. Given its essential significance, the security of surveillance system data transmission plays a critical role. On the one hand, authorized entities must be capable of detecting any malicious data interception, and on the other hand, confidential information must remain safeguarded when an eavesdropper is identified. To address transmission security, we have developed a quantum-communication-based system for transmitting surveillance imagery of the hazardous chemical storage area entrance. This system effectively thwarts eavesdropping and data tampering during transmission, thereby enhancing the security of conventional monitoring systems.
Unraveling the Phylogenetic Relationships and Taxonomic Status of a Puzzling Freshwater Mussel Genus Inversidens (Bivalvia, Unionidae) through Multilocus Phylogeny and Mitochondrial Phylogenomics

Published: January 2024

Accurate phylogenetic reconstructions are crucial for comprehending the evolutionary histories, reproductive traits, and ecological habits of organisms. The subfamily Gonideinae of freshwater mussels is currently thought to include eight tribes. However, due to inadequate taxon sampling and molecular data, the assignment of the freshwater mussel genus Inversidens at the tribe level has been unstable. Additionally, the lack of phylogenetic data has hindered efforts to understand the basic biology and implementation of conservation efforts of Inversidens rentianensis, an endemic species to China. Here, we first present the complete mitochondrial genome of Inversidens rentianensis and offer a detailed description of its anatomical morphology. Based on DNA sequence data from five genes (COI, ND1, 16S rRNA, 18S rRNA, and 28S rRNA) and complete mitochondrial genomes, we investigated the phylogenetic position of Inversidens using various analytical methods. Both the concatenated five-gene and mitogenome datasets strongly supported that Inversidens classified to the tribe Gonideini in Gonideinae and formed a basal clade within the tribe Gonideini. Molecular dating analysis suggested that Inversidens originated during the mid-Cretaceous era (102.73 Mya, 95% highest posterior density HPD=72.22‐137.03 Mya) and underwent diversification in the Late Paleogene era (37.92 Mya, 95% HPD=20.39‐60.59 Mya). Moreover, based on the Quantitative Assessment of Species for Conservation (QASCP), Inversidens rentianensis is ranked as second priority, providing valuable insights for its management and conservation efforts. Taken together, this study provides a comprehensive understanding of the systematic position and evolutionary history of Inversidens within the currently accepted subfamily Gonideinae classification framework. These findings establish a solid foundation for future investigations on the ecology, reproductive behavior patterns, and conservation biology of this taxonomic group.

A Static-Dynamic Hypergraph Neural Network Framework Based on Residual Learning for Stock Recommendation
Authors: Hao Jianlong , Liu Zhibin , Sun Qiwei , Zhang Chen , Wang Jie
Published: January 2024

Stock ranking prediction is an effective method for achieving a high investment return and plays a crucial role in investment decisions. However, previous studies have overlooked the interconnections among stocks or have solely relied on predefined graphs for stock relationship information. The predefined graphs may not capture all possible relationships and may not be suitable for describing dynamic relationships. To address these issues, we propose a Static-Dynamic hypergraph neural network framework based on Residual Learning (SD-RL). Compared with traditional methods, SD-RL has the following advantages. (1) Stocks are no longer treated as isolated entities; instead, their static and dynamic relationship information is taken into account. (2) Leveraging the data-driven methodology, SD-RL autonomously learns both the static graph and dynamic hypergraph through dedicated graph learning and hypergraph learning modules, respectively. (3) By employing residual learning, various latent relationship information flows are mined, which enhances the stock embedding’s capacity to capture trends. Extensive experiments on the real data verify the effectiveness of our proposed methods.

Authors: Stemmer Shlomo M. , Gomes Cintia , Cardonick Elyce H.
Published: January 2024

Desmoid fibromatosis (DF) is a rare and locally aggressive neoplasm. We present a case of a 28-year-old previously healthy multigravida who noticed a lump in her abdomen near the umbilicus two months before becoming pregnant. It underwent rapid growth during pregnancy, causing pain and discomfort. Targeted ultrasound of the area showed an irregular mass measuring 0.9×1.7×1.4 cm. The origin of the mass was unclear, suggesting a connection with the intra-abdominal contents. An MRI done three weeks later revealed a subcutaneous ovoid mass measuring 3.0×2.3×3.0 cm, which was significantly larger. Due to pain and rapid growth, surgical resection was done at 25 weeks of pregnancy. Histopathological examination revealed a desmoid tumor. The patient had an uneventful recovery and term vaginal delivery without complications. Hence, our case serves as evidence that DF tumors can be surgically managed during pregnancy with minimal to no complications.

Using Nafion212 membrane and TEOS solution as raw materials, Nafion212/SiO2 composite membranes were prepared. In the in situ sol‐gel reaction process, a series of Nafion/SiO2 composite membranes were prepared by varying the reaction temperature and reaction time. The effects of different modification schemes on Nafion/SiO2 composite membranes were studied using SEM, EDS, TEM, TGA, XRD, and mechanical tensile experiments, among other methods. The results show that Nafion/SiO2 composite membranes prepared at 3°C exhibit a well‐separated phase structure and excellent water retention properties, with a water uptake of 29.23% and a swelling ratio of 24.25%. These membranes also demonstrate outstanding physical and chemical performance, with a maximum tensile stress of 13.6 MPa and an elongation at a break of 270%. At 110°C, the proton conductivity of the Nafion/SiO2 composite membrane reaches 0.172 S/cm, meeting the requirements for high‐temperature proton exchange membrane fuel cells.

Published: January 2024

Introduction. The use of thyroid hormone supplementation (THS) for donor optimization has not been standardized and remains an area of academic investigation and clinical interest. The purpose of this study is to investigate the impact of THS supplementation on heart transplant recipient outcomes. Methods. Adult heart transplant recipients in the UNOS database recorded from January 1, 2000 to June 30, 2022 formed the study cohort. Simple comparisons were made with t‐tests or chi‐squared tests. Logistic regression models were used to predict 30 day and 1 year survival. Accelerated failure time models were employed to analyze time to death and time to rejection. Results. The cohort consisted of 46,542 heart transplants, of which 28,911 (62%) received THS prior to organ procurement. In adjusted models, donor THS was associated with a reduction of 11% in the odds of death within 30 days (OR = 0.89; p = 0.048); however, this relationship did not extend to one year post‐transplant survival (OR = 1.00; p = 0.968). After a sex‐based analysis, 30‐day survival benefit was seen only in male‐to‐male donor‐recipient pairings (OR for death = 0.82; p = 0.007). Overall survival and post‐transplant rejection was also improved in the male‐to‐male group (HR = 0.94; p = 0.002 and HR = 0.96; p = 0.048) and the female‐to‐female group (HR = 0.87; p = 0.003 and HR = 0.90; p = 0.013). There was no associated survival benefit with THS in sex mismatched groups. Conclusion. THS in donors is associated with improved 30‐day post‐transplant survival and overall survival after OHT in sex‐matched donor‐recipient pairs. Further study is warranted.

Published: January 2024

Background. Vancomycin‐resistant Enterococci (VRE) is a global health problem and responsible for healthcare‐associated infections (HAIs) in patients with prolonged hospital stay, severe underlying disease, and previous broad‐spectrum antibiotic therapy. These bacteria can cross‐resist and transfer drug‐resistant genes to other potentially pathogenic bacteria. Therefore; this study was aimed to determine the gastrointestinal colonization rate of VRE, its antimicrobial susceptibility profile, and associated factors among hospitalized patients. Methods. Prospective cross‐sectional study was conducted using stool samples from 223 patients admitted to different wards at Hawassa University Comprehensive Specialized Hospital, from April 1 to June 30, 2021. Patients admitted to the hospital for more than 48 hours for various medical conditions were included. Sociodemographic and clinical characteristics were collected using a structured questionnaire. Fecal specimens were cultured on Enterococci selective media. Enterococcus species were identified using their growth and mannitol fermentation properties. Vancomycin resistance was screened using both the Kirby–Bauer disk diffusion method and a vancomycin E‐test strip. Data were entered and analyzed using SPSS version 25. Descriptive and logistic regressions were used to determine the frequency and association of factors with the VRE colonization rate. A p value of <0.05 was considered statistically significant. Results. A total of 223 fecal specimens were collected and processed, and 141 (63.2%) them were positive for Enterococci. The predominant species was E. faecalis 65 (46.1%) followed by E. faecium 76 (53.9%). In this study, the gastrointestinal colonization rate of VRE was 15 (6.7%) and all the species belong to E. faecium. Study participants who had no formal education (AOR = 4.26, 95% CI: 1.01, 18.06), hospitalized patients for >2 weeks (AOR = 4.10, 95% CI: 1.08, 15.57), and those who had a history of treatment with vancomycin (AOR = 4.77, 95% CI: 1.26, 18.09) were more likely to be colonized with vancomycin‐resistant Enterococci. More than 95% of Enterococci isolates were susceptible to linezolid, whereas 70.2%, 63.1%, 56.7%, and 53.9% were resistant to tetracycline, erythromycin, penicillin, and ampicillin, respectively. Among the total Enterococci isolated, 141 (54.6%) were multidrug resistant. Conclusions. In our study, high proportion of vancomycin‐resistant Enterococci was found. Previous exposure to antibiotics and hospital stay were significant factors for VRE gut colonization. The isolated Enterococci showed variable degrees of resistance to commonly prescribed antibiotics which leads to a worldwide problem multidrug resistance. Therefore, periodic surveillance on antimicrobial resistance pattern, adhering to rational use of antibiotics, and implementing infection prevention protocols may reduce colonization by VRE.
A Case Study on Preservation Conditions and Influencing Factors of Shale Gas in the Lower Paleozoic Niutitang Formation, Western Hubei and Hunan, Middle Yangtze Region, China

The Niutitang Formation of the lower Cambrian (Є1n) is a target reservoir of shale gas widely developed in China’s Middle-Upper Yangtze region, with the characteristics of being widely distributed, having a big thickness and highly organic carbon abundance. However, the exploration and research degree are relatively low. Based on extensive core sample, experimental test results, drilling, and field outcrop surveying, the shale gas generation capacity, gas content, and gas composition are discussed. The preservation conditions of shale gas are then systematically analyzed from the aspects of tectonic movement, fault development, structural style, and thermal evolution degree. The results show that the organic-rich shale with a thickness ranging from 40 to 150 m developed in the mid-lower part of the Є1n Formation, with the TOC content values ranging from 0.4% to 14.64%. While it has unfavorable characteristics of a high thermal evolution, with Ro values ranging from 1.92% to 5.74%, a low gas content and a high nitrogen content (70% wells). The Є1n shale gas has complex preservation conditions. The Є1n Formation has good roof-to-floor conditions, but after the main gas generating peak of the Є1n shale during the Jurassic–Cretaceous, the most intensive tectonic activity of the Yanshan movement resulted in poor preservation conditions (faults developed and cap rock fractured). The huge faults extended to the surface are formed due to tectonic movement in an extensional environment, and the structural style and development are the main factors affecting the preservation conditions of the Є1n shale gas. Additionally, the high thermal evolution of the Є1n shales also has a certain impact on the preservation conditions. Therefore, the stable area far from large faults (>2.0 km), with weak local tectonic activity and tectonic deformation, is the favorable area for shale gas preservation in the Є1n Formation.

Background. Despite the high prevalence of intimate partner violence (IPV) against women in India (33%), there are persistently low rates of disclosure and help‐seeking amongst survivors. The aim of this study was to explore both coping strategies employed by survivors and the perceived barriers and facilitators to seeking support from informal and formal resource networks. Methods. We conducted semistructured, in‐depth qualitative interviews with thirty‐five women survivors of IPV in Goa, India, in secure, private locations, utilizing flipcharts and vignettes to elicit deeper insights into efficacies of support resources. The data were transcribed, translated, and analyzed utilizing qualitative content analysis. Results. The most common coping mechanisms cited by survivors involved passive resistance, such as self‐distraction, keeping quiet during violent outbursts, and leaving the home temporarily. Generally, survivors sought support from informal support networks (the natal family, in‐laws, neighbors/community members, and close friends) before approaching formal support structures (medical/legal professionals, professors, police, and nongovernment organizations). In fact, informal structures were often facilitators of formal help‐seeking. Survivors sought help at various stages of their marital relationship. Primary deterrents to help‐seeking included the normalization of IPV by survivors and providers alike, resulting in the stigmatization of disclosing experiences of IPV and ostracism of survivors and close relatives; another barrier was a general lack of awareness of existing support resources. Conclusion. Our findings reveal that there are numerous barriers to help‐seeking and shortcomings of support resources. Survivors’ evaluations of support resources reveal that robust, community‐level, and meso‐level structural changes are required to promote help‐seeking behaviors, including the destigmatization of IPV amongst providers and broader society and raising awareness of available support resources.

Aims. This study aimed to explore workload whether Nursing Activities Scores on one shift could predict workload for the next shift. Method. This was a retrospective observational exploratory study of cross-sectional design carried out in a postoperative and intensive care unit at a local, nonprofit hospital in Norway. Data were collected from the hospital’s internal database from January 1st to June 30th, 2016. Results. A total of 2,695 patients and 5,916 Nursing Activities Scores were included. The model could predict a 55.1% to 66.9% variation in Nursing Activities Scores for the next shift. When the number of patients was added, the model explained up to 80% of the variation. Conclusions. The Nursing Activities Score can be used to predict nursing workload from one shift to another and as an instrument for managers to adjust their staffing requirements. Implications for Nursing Management. Nursing Activities Score assessing nursing workload for all patients in a unit can support the resource planning with accuracy for nurse staffing.

Therapy resistance and metastatic progression are primary causes of cancer-related mortality. Disseminated tumor cells possess adaptive traits that enable them to reprogram their metabolism, maintain stemness, and resist cell death, facilitating their persistence to drive recurrence. The survival of disseminated tumor cells also depends on their ability to modulate replication stress in response to therapy while colonizing inhospitable microenvironments. In this study, we discovered that the nuclear translocation of AXL, a TAM receptor tyrosine kinase, and its interaction with WRNIP1, a DNA replication stress response factor, promotes the survival of HER2+ breast cancer cells that are resistant to HER2-targeted therapy and metastasize to the brain. In preclinical models, knocking down or pharmacologically inhibiting AXL or WRNIP1 attenuated protection of stalled replication forks. Furthermore, deficiency or inhibition of AXL and WRNIP1 also prolonged metastatic latency and delayed relapse. Together, these findings suggest that targeting the replication stress response, which is a shared adaptive mechanism in therapy-resistant and metastasis-initiating cells, could reduce metachronous metastasis and enhance the response to standard-of-care therapies.

Significance:

Nuclear AXL and WRNIP1 interact and mediate replication stress response, promote therapy resistance, and support metastatic progression, indicating that targeting the AXL/WRNIP1 axis is a potentially viable therapeutic strategy for breast cancer.
