Circumventing volumetric locking in stabilized smoothed particle finite element method and its application to dynamic large deformation problems

The smoothed particle finite element method (SPFEM) is an effective framework for large deformation analysis. The original SPFEM possesses the rank deficiency issue due to the direct nodal integration technique, which can be overcome by incorporating the strain gradient stabilization method. However, an extra volumetric locking due to the strain gradient stabilization term has been found. In this study, we propose a simple and efficient approach, the B‐dev approach, which only considers the deviatoric part of the smoothed strain gradient for stabilization to overcome the volumetric locking issue. First, the correctness of the stabilized SPFEM method is verified by an elastic cantilever beam vibration problem without considering incompressibility. Then, through the example of the strip footing penetration problem, the volumetric locking in the stabilized SPFEM is demonstrated and the capability of the proposed B‐dev approach in terms of overcoming the volumetric locking is verified. Furthermore, the stabilized SPFEM with B‐dev approach is applied to two types of elastoplastic problems in geotechnical engineering. All numerical results illustrate that the proposed approach can improve the performance of the stabilized SPFEM in dealing with incompressible and large deformation problems in geomechanics.
Socio-cultural practices and stress among working mothers of underage children in the Public Universities of Nigeria

The study examined the sociocultural factors that bring about stress to working mothers of underage children at the University of Nigeria, Nsukka by recruiting 504 academic and non-academic staff. To assess the study variables in a cross-sectional survey, a questionnaire, and an in-depth interview schedule were employed in collecting data from working mothers of underage children in the University of Nigeria, Nsukka. The Chi-square (? 2) statistical analysis indicated that there is a significant relationship between the husband’s attitude towards domestic duties and the stressful experience of working mothers with underage children. The data also demonstrated that there is no statistically significant relationship between the husband’s educational status and the stressful experience of working mothers with underage children. The study concluded that the husband’s attitude is a significant predictor of working mothers of underage children’s stress experience. It was, therefore, recommended that policies should be enacted by the Nigerian government and enforced in public sectors to enhance ‘favorable’ working conditions for working mothers of underage children. This should include an extension of maternity leave to at least six months, less demanding/accommodative job times, and assigned duties in tunes that do not compromise the ethos of a given profession.
Supplementary White, UV-A, and Far-Red Radiation Differentially Regulates Growth and Nutritional Qualities of Greenhouse Lettuce

Light is a crucial environmental signal and a form of photosynthetic energy for plant growth, development, and nutrient formation. To explore the effects of light quality on the growth and nutritional qualities of greenhouse-grown lettuce (Lactuca sativa L.), lettuce was cultivated under supplementary white (W) light-emitting diodes (LEDs); white plus ultraviolet A LEDs (W+UV); white plus far-red LEDs (W+FR); and the combination of white, far-red, and UV-A LEDs (W+FR+UV) for 25 days, with lettuce grown under natural sunlight used as the control. The results indicate that the leaf length and leaf width values for lettuce grown under the W+FR+UV treatment were significantly higher than those of lettuce grown under other supplementary light treatments. The highest values of shoot fresh weight, shoot dry weight, root fresh weight, and root dry weight were recorded under the W+FR treatment (4.0, 6.0, 8.0, and 12.4 times higher than those under the control treatment, respectively). Lettuce grown under the W+FR treatment exhibited the highest total chlorophyll content (39.1%, 24.6%, and 16.2% higher than that under the W, W+UV, and W+FR+UV treatments, respectively). The carotenoid content of lettuce grown under the W+FR treatment was the highest among all treatments. However, the root activity of greenhouse-grown lettuce was the highest under the W+FR+UV treatment. Soluble sugar content, cellulose content, and starch content in the lettuce responded differently to the light treatments and were highest under the W+UV treatment. In summary, supplementary light promoted growth and nutrient accumulation in lettuce. Specifically, white plus far-red light promoted lettuce growth, and white plus UV increased some specific compounds in greenhouse-grown lettuce. Our findings provide valuable references for the application of light-supplementation strategies to greenhouse lettuce production.
Vesicular Release and Uptake of Circular LSD1-RNAs from Non-Cancer and Cancer Lung Cells

Lysine-specific demethylase 1 (LSD1) is highly expressed in many cancer types and strongly associated with cancer progression and metastasis. Circular RNAs (circRNAs) are produced by back-splicing and influence the interactive RNA network by microRNA and protein sponging. In the present study, we aimedto identify circRNAs that derive from the LSD1-encoding KDM1A gene, and to investigate their potential to be released and uptaken by lung cancer versus non-cancer epithelial cells. We identified four circLSD1-RNAs by RT-PCR with divergent primers, followed by sequencing. The expression level of circLSD1-RNAs was then studied by quantitative PCR on cellular and extracellular fractions of lung cancer (PC9) and non-cancer primary small airway epithelial (PSAE) cells. Moreover, we established the transgenic overexpression of circLSD1-RNAs. We show that circLSD1-RNAs are primarily located in the cytoplasm, but are packaged and released from lung cancer and non-cancer cells by extracellular vesicles (EVs) and ribonucleoprotein (RNP) complexes, respectively. Proteomics demonstrated a different protein pattern of EV fractions released from PC9 versus PSAE cells. Importantly, released circLSD1-RNAs were differently taken up by PSAE and PC9 cells. In conclusion, our findings provide primary evidence that circLSD1-RNAs participate in the intercellular communication of lung cancer cells with the tumor environment.
An Introduction to Second-Generation p-Values

ABSTRACT Second generation p-values preserve the simplicity that has made p-values popular while resolving critical flaws that promote misinterpretation of data, distraction by trivial effects, and unreproducible assessments of data. The second-generation p-value (SGPV) is an extension that formally accounts for scientific relevance by using a composite null hypothesis that captures null and scientifically trivial effects. Because the majority of spurious findings are small effects that are technically nonnull but practically indistinguishable from the null, the second-generation approach greatly reduces the likelihood of a false discovery. SGPVs promote transparency, rigor and reproducibility of scientific results by a priori identifying which candidate hypotheses are practically meaningful and by providing a more reliable statistical summary of when the data are compatible with the candidate hypotheses or null hypotheses, or when the data are inconclusive. We illustrate the importance of these advances using a dataset of 247,000 single-nucleotide polymorphisms, i.e., genetic markers that are potentially associated with prostate cancer.

The Impact of Pulmonary Vein Anatomy on P-Wave Appearance during Sinus Rhythm: Cardiac Computed Tomography Study

Electrocardigraphy remains a first-line evaluation method for cardiac electrical activity, recorded from the body surface. Since atrial activation is seen on the ECG as a P-wave, several factors are known to impact the appearance of the P-wave, such as the direction of electric impulse, conduction abnormalities, and anatomical characteristics of the atria. This retrospective study aimed to find statistically significant associations between the anatomy of pulmonary veins (PVs) observed in cardiac computed tomography (CT) and P-wave appearance during sinus rhythm on resting ECG. For each patient, a resting 12-lead ECG was recorded, and the field of analysis was P-wave—its duration, morphology, and axis. The evaluation of the CT scan recordings was performed by creating 3D models of the left atrium and analyzing the anatomy of the PVs and left atrial appendages (LAA). Noteworthy correlations were found: anatomy of the left PVs showed an association with LAA volume, LAA morphology, and P-wave notching in lead II. The right PVs demonstrated a relation with the P-wave axis and amplitude. Although these correlations cannot be classified as strong, the results not only expand understanding about discussed variables but also suggest the presence of a subtle and complex relationship, that warrants further exploration.
Ocular Protection Practice and Associated Factors Among Ethiopian Welders: Institution-Based Cross-Sectional Study

Introduction Work-related ocular injury is a global public health problem, particularly among welders and is reduced through proper ocular protection practice. No previous studies have explored ocular protection practice and associated factors among welders in Ethiopia or in the study area. Objective This study aimed to assess the proportion of ocular protection practice and associated factors among welders in Gondar city, Northwest Ethiopia. Methods An institution-based cross-sectional study was conducted among 403 welders in Gondar city, selected using systematic random sampling with an interval of 2, from July 6 to 23, 2021. Data were collected using a pre-tested structured questionnaire and an observational checklist. Binary logistic regression was used to identify factors associated with ocular protection practice and association was expressed using an adjusted odds ratio with a 95% confidence interval (CI). Variables with a P-value of less than 0.05 were considered statistically significant. Results Of 396 participated welders, 81.8% worked without job training, and 33.1% had faced ocular injury. Nearly 86% of welders had access to personal protective eyewear but their knowledge and attitude towards personal protective eyewear were 48.2% (95% CI: 44.8, 51.4) and 61.4% (95% CI: 57.6, 64.7), respectively. The proportion of a good-level of ocular protection practice was 56.8% (95% CI: 52.8, 61.9). Being gas welder (adjusted odds ratio [AOR]=0.26, 95% CI: 0.12, 0.53), work experience (AOR = 1.10, 95% CI: 1.01, 1.21), job training (AOR = 4.90, 95% CI: 2.32, 10.35), welders rated the cost of personal protective eyewear as fair (AOR = 2.30, 95% CI: 1.26, 4.20) and history ocular injury (AOR = 4.20, 95% CI: 2.40, 6.97) were positively associated with a good-level proportion of ocular protection practice. Conclusion This study found that the proportion of a good-level of ocular protection practice of welders was fair. Being gas welder, job training, work experience, history of ocular injury and welders rated the cost of personal protective eyewear as fair were significantly associated with a good-level of ocular protection practice.
How L1-Mandarin L2-English learners perceive English front vowels: A phonological account

Second language acquisition involves readjusting features from one’s L1 onto counterparts in the L2. Learners often face difficulty during this process due to the presence of an already firmly rooted L1 grammar. Furthermore, a learner’s L1 serves to constrain sensitivity to non-native contrasts during the acquisition process. If a learner’s L2 grammar lacks the phonological feature that can differentiate a non-native contrast, then that learner may experience persistent difficulties in representing the L2 sounds as a result. Mandarin learners of English as a second language have to contend with a substantially expanded L2 vowel inventory in the early stages of acquisition, grappling with the addition of pronounced features less prevalent in their L1. In an attempt to account for front vowel acquisition difficulties and possible routes to progress for L1-Mandarin L2-English using a direct transfer approach, this work follows the Toronto School of contrastive phonology which holds that phonological representation is determined primarily through the ordering of contrastive features. We present data from recent phonetic research that catalogues Mandarin learners’ progress in incorporating English front vowels while, at the same time, examining the underlying phonological processes. This serves as the basis for a preliminary model of contrastive hierarchy in language acquisition using elements of a feature geometry paradigm. The model provides a theoretical roadmap showing that, as Mandarin learners progress and gradually incorporate English front vowels into their L2 repository, the learner’s L2 hierarchy evolves through successive stages as contrasts are perceived and categorized.
Characterization of the complete plastid genome and phylogenetic implication of Micranthes octopetala (Nakai) Y.I.Kim & Y.D.Kim (Saxifragaceae), endemic to Korea

Abstract Micranthes octopetala (Nakai) Y.I. Kim & Y.D. Kim et al. 2015, which belongs to the family Saxifragaceae, is a perennial herb endemic to Korea. M. octopetala was originally treated as a synonym of M. manchuriensis. However, in 2015, molecular phylogenetic analysis confirmed that M. octopetala is an independent species. In this study, the plastid genome of M. octopetala was sequenced for the first time, and the taxonomic position of this species was identified. The complete plastid genome of M. octopetala has a total length of 149 751 bp (large single copy: 83 083 bp; small single copy: 17 196 bp; inverted repeat: 24 736 bp), containing 130 genes, including 79 CDS, 30 tRNAs, and 4 rRNAs. Moreover, the absence of intron in the rpl2 gene, which is a common feature of Saxifragaceae, was confirmed. Phylogenetic analysis based on 79 protein-coding genes from 21 species revealed that M. octopetala belongs to the genus Micranthes, being a sister to other Micranthes species. The plastid genome of M. octopetala obtained in this study provides fundamental information for future studies on the genus Micranthes.
The Current Status of the Liver Liquid Biopsy in MASH Related HCC: Overview and Future Directions

Metabolic dysfunction-associated steatohepatitis (MASH) is one of the major risk factors for chronic liver disease and hepatocellular carcinoma (HCC). The incidence of MASH in Western countries continues to rise, driving HCC as the third cause of cancer-related death worldwide. HCC has become a major global health challenge, partly from the obesity epidemic promoting metabolic cellular disturbances but also from the paucity of biomarkers for its early detection. Over 50% of HCC cases are clinically present at a late stage, where curative measures are no longer beneficial. Currently, there is a paucity of both specific and sensitive biological markers for the early-stage detection of HCC. The search for biological markers in the diagnosis of early HCC in high-risk populations is intense. We described the potential role of surrogates for a liver biopsy in the screening and monitoring of patients at risk for nesting HCC.

The association of Sirtuin1 (SIRT1) polymorphism and downregulation of STAT4 gene expression with increased susceptibility to COVID-19 infection

ABSTRACT Sirtuin1 (SIRT1) is an epigenetic modulator that belongs to sirtuins family and participates in many physiologic reactions, as genomic stabilization, apoptosis, proliferation, and inflammation. STAT4 (signal transducer and activator of transcription 4) gene is a component of JAK-STAT signaling pathway, which plays key role in activating cellular-mediated immune responses. The present study aimed to investigate the association between SIRT1 rs12778366 SNP, expression level of STAT4 gene and susceptibility to COVID-19 infections as well as their correlation to clinicopathological data. The present study included 100 ICU patients with severe COVID-19 infection and 100 age- and sex-matched healthy controls. DNA was extracted. Genotyping of SNP in SIRT1 (rs12778366) was performed, Total RNA was extracted from PBMCs. Reverse transcription was done. STAT4 gene expression levels were evaluated with GAPDH as internal control using real-time PCR. We found a significantly higher frequency of ‘C’ allele and C/T genotype in case vs. control. The association was of low strength (φ = 0.105 for alleles, and 0.154 for genotypes). This was associated with higher expression of STAT4 gene (P < 0.001) and increased tendency for lower respiratory complications. Median STAT4 (FC) (Median = 0.18, 95% CI = 0.15–0.27) was lower than normal control value of 1.0. This difference was statistically significant (Hodges-Lehmann location estimator = 0.217, P < 0.001). SIRT1 polymorphism and decreased expression of STAT4 gene are associated with increased susceptibility to COVID-19 infection and correlate to its phenotypic manifestations.
Facial Expression Recognition Using Light Field Cameras: A Comparative Study of Deep Learning Architectures

This paper presents our contribution to facial expression recognition using images obtained from the Light Field Face Dataset(LF). We compare several variants of neural network architectures to demonstrate the potential benefits of using this relatively new optical system in the field of facial expression recognition. We propose the use of the EfficientNetV2-S convolutional neural network as the base architecture, combined with various recurrent neural networks (LSTM, GRU, BiLSTM, and BiGRU) in our experiments. Furthermore, we investigate different sets of sub-aperture images, each varying in terms of the number of images and virtual position. The results demonstrate a significant improvement in accuracy for two specific configurations, depending on the sets of sub-aperture images used. The first configuration involves using the EfficientNetV2-S model in a two-branch configuration combined with an LSTM. The second configuration uses a single branch model with a BiLSTM.
Linguistic Markers of Inherently False AI Communication and Intentionally False Human Communication: Evidence From Hotel Reviews

To the human eye, AI-generated outputs of large language models have increasingly become indistinguishable from human-generated outputs. Therefore, to determine the linguistic properties that separate AI-generated text from human-generated text, we used a state-of-the-art chatbot, ChatGPT, and compared how it wrote hotel reviews to human-generated counterparts across content (emotion), style (analytic writing, adjectives), and structural features (readability). Results suggested AI-generated text had a more analytic style and was more affective, more descriptive, and less readable than human-generated text. Classification accuracies of AI-generated versus human-generated texts were over 80%, far exceeding chance (∼50%). Here, we argue AI-generated text is inherently false when communicating about personal experiences that are typical of humans and differs from intentionally false human-generated text at the language level. Implications for AI-mediated communication and deception research are discussed.
