Authors: Franceschette Claudia , Valentín Kevin André , Zapata-Cardona Lucía
Published: October 2024

Las concepciones del profesorado, como un componente de su cognición, determinan las decisiones y acciones inclusivas en el aula de matemática en un momento en el que el número de estudiantes con trastorno del espectro autista ha aumentado en los sistemas escolares del mundo. Este estudio investigó las concepciones del profesorado de matemáticas sobre la inclusión de estudiantes con trastorno del espectro autista. Se usó un paradigma empírico-analítico basado en el diseño y aplicación de un cuestionario con un componente demográfico y una escala Likert de 70 ítems. Los informantes fueron 110 profesores de matemáticas voluntarios de diferentes niveles en instituciones educativas de carácter público o privado de Colombia. Los resultados sugieren que el profesorado tiene en general concepciones positivas sobre la inclusión escolar de estudiantes con trastorno del espectro autista, pero las concepciones no son tan positivas cuando se refieren a la inclusión de estos estudiantes en la clase de matemáticas. Este estudio sugiere la necesidad de formación continua del profesorado para atender con pertinencia la inclusión escolar en la clase de matemáticas.

The experimental conditions were reproduced in numerical experiments. The mathematical model of viscous compressible gas was used to model the gas dynamics of supersonic gas jets. The problem was solved in a two-dimensional axisymmetric setting for argon. The obtained distributions of the main gasdynamic quantities made it possible to detail the flow features and estimate the size of the emission zone, as well as the density level corresponding to this zone. It was demonstrated that the results of calculations qualitatively agree with the experimental data. In addition, it was found that the density level of the emission region with the required extreme ultraviolet intensity factor can be obtained by monitoring the total pressure.
Approximate Riemann Solvers for the Soave – Redlich – Kwong Equation of State
Authors:   Udmurt Federal Research Center UB RAS, Koroleva M. R. ,   Kalashnikov Izhevsk State Technical University, Tenenev V. A.
Published: October 2024

Three methods for constructing an approximate Riemann solver for the Soave – Redlich – Kwong real gas model are presented: linearization of nonlinear equations, cubic interpolation, and local approximation of the equation of state by a two-term equation of state. These methods are tested by considering the problem of the decay of a discontinuity in a pipe in an axisymmetric setting for the low-molecular and high-molecular substances, including a region of nonclassical gas behavior. It is demonstrated that the linearization method is reasonable only for the testing problems. The method of approximation by cubic splines is acceptable for complex three-dimensional nonstationary calculations. However, it is found that the bicubic interpolation method does not work well for flows with large pressure drops. The local approximation method is the most economical and universal for practical calculations. It has been used for numerical modeling of real gas flows through a safety valve. The results of calculations for hydrogen and water vapor in a wide range of pressure variation are presented. The method of local approximation of the equation of state allows one to describe all features of gas flows for complex problems.
Truth Politics and Social Media
Authors: Cvrtila Leon
Published: October 2024

Social media platforms continue to struggle with the proliferation of falsehoods, despite years of fervent calls to address the issue and recent attempts at regulation. In social science literature this issue is mostly approached with the motive of identifying and suppressing false information, advocating for institutional action to restore truth. This article proposes approaching the matter through the notion of truth politics, derived from the works of Michel Foucault, with the focus on investigating the power dynamics that determine the possibilities of truth in the present. The article lays out the requisite theoretical and conceptual elements. First, by distinguishing between different uses of the term “truth” in Foucault’s writings, the emphasis is shifted from epistemic evaluation of truth claims to the analysis of the conditions of possibility of truth. Second, the crucial concept – truth regime – is presented as it appears in Foucault’s work. Third, the concept of truth regime is further developed to make it applicable to technical systems. Fourth, the paper provides an example of technological operation of truth regimes using the case of Facebook’s News Feed algorithm

Authors: Juhri Muhammad Alan
Published: October 2024

This paper investigates how interfaith dialogue discourse is now developing significantly with the role of social media and youth. Based on online research and virtual ethnography, this paper argues that creatively utilizing social media with involving youth as media-savvy is the main factor in significantly increasing the acceptance of interfaith dialogue discourse. In-depth content analysis with a focus on interfaith dialogue through YouTube podcasts reveals several strategies applied by the creator. This paper highlights several strategies, namely using hashtag and maximizing thumbnail, propagating podcasts with clickbait titles, consistenly uploading content, and connecting with other platforms. In addition, youth involvement also plays an important role in achieving significant interfaith dialogue such as by engaging them with humor and comedy, eye-catching appearance and millennial style, and visual persuasion. Finally, great acceptability achieved by interfaith podcasts on youtube has proven the existence of religious inclusivity in Indonesia.

Published: October 2024

Case:

We report the case of a 44-year-old man who sustained an Achilles tendon rupture with an associated trimalleolar fracture and traumatic peroneal dislocation of the left ankle after a snowboarding injury. These injuries have been surgically repaired; the patient has returned to all his activities 18 months after surgery.

Conclusion:

The possibility of such injuries occurring in combination should be considered. A thorough history, physical examination, and plain radiographs should be performed in higher energy trauma to the ankle. Additional diagnostic tests such as ultrasonography or magnetic resonance imaging may be used to supplement treatment.

When Is a Clay-Shoveler's Fracture, Not a Clay-Shoveler's Fracture?
Authors: Schultz Matthew J. , Wheeler Michael R. , Black Loren O. , Morrell Aidan T. , Philipp Travis C.
Published: October 2024

Case:

A 71-year-old man with a history of C5-7 anterior cervical discectomy and fusion (ACDF) sustained a C7 spinous process fracture after falling from a ladder. He was initially managed nonoperatively but developed anterolisthesis and kyphosis at C7-T1 with left hand weakness over the course of 11 days. Surgical treatment included spinous process wiring and C5-T3 posterior fusion. At 14-month follow-up, he demonstrated resolution of pain and returned motor function.

Conclusion:

The patient's ACDF likely created a longer lever arm, allowing the force of his fall to be concentrated at C7-T1. Patients with a suspected Clay-Shoveler's fracture require close follow-up.

Authors: Cagan Basak Bilcanoglu , Karakaya Huseyin , Yilmaztekin Murat
Published: October 2024

Green tea (Camellia sinensis) is intensely consumed all over the world and tea leaves discarded from production are a rich source of catechins, especially epigallocatechin-3-gallate (EGCG). This study aimed to perform preparative separation of EGCG from green tea waste by using macroporous resin and to reveal adsorption and desorption characteristics. Nine types of resins were compared for their adsorption and desorption capacities and desorption rate of EGCG, and NKA-2 was found the most suitable resin for the purpose. Adsorption isotherms were evaluated at 25°C, 35°C and 45°C. Experimental data was well described with pseudo-second order kinetics model and fitted best to the Langmuir model in tested temperatures. In dynamic separation process, 83% of adsorbed EGCG was recovered from the resin by using 70% ethanol. It has been thought that using macroporous resin can be an effective way of EGCG separation from green tea waste for commercial purposes.

Published: October 2024

Yardlong bean (Vigna unguiculata) is a healthy vegetable that is popular in Southeast Asia. Farmers have frequently used pesticides while planting in order to avoid and eradicate pests. Utilising biofertilizer with microorganisms included to help with growth promotion and disease management is one such tactic. The aims of this study were to (1) produce granular biofertilizer amended with Bacillus amyloliquefaciens to control Sclerotium rolfsii-caused root and stem rot disease and (2) assess its effect on the growth of yardlong bean (Vigna unguiculata subsp. sesquipedalis). The bacterium which inhibited S. rolfsii, had the capacity to solubilize phosphate, enhanced the growth of yardlong beanand not antagonistic to Rhizobium TAL 638 was identified as B. amyloliquefaciens (HY 4-3-4). The granular biofertilizer that was created and included this bacterium (at 8.96 Log. number/g) continued to be efficient in inhibiting the mycelial growth of S. rolfsii even after 16 months of storage at room temperature (26–30°C). In the pot, granular biofertilizer was effective to control root and stem rot of the yardlong bean. The yardlong bean's stem length, fresh and dry weight, and number of nodules on the roots were all effectively increased by this granular biofertilizer. In the field, the granular biofertilizer was as effective as a chemical fungicide (mancozeb) to control root and stem rot of the yardlong bean. Thus, employing biofertilizers contributes to environmental sustainability by lowering the amount of chemicals used in growing yardlong bean.

Published: October 2024

Rhipicephalus microplus poses a significant challenge to the livestock industry, leading to substantial economic burdens. Traditionally, chemical acaricides have been the primary management strategy; however, their indiscriminate use has led to resistance, environmental contamination, and health risks. Therefore, there is growing interest in exploring alternative approaches, such as entomopathogenic fungi like Metarhizium anisopliae. This study aimed to evaluate the effectiveness of M. anisopliae isolates from Malaysia against R. microplus using the Adult Immersion Test protocol. Engorged female ticks were utilized in the bioassay. The experiment involved applying M. anisopliae isolates (1518, 1521, 1522, PR1, HSAH5, and GT3) at a concentration of 108 through tick immersion. Mortality rates were monitored for 14 days, with experiments conducted in triplicate. Result showed that PR1 exhibited the highest virulence, causing 83.33% mortality within 14 days. There was no significant difference between the isolates in their ability to cause tick mortality. However, probit analysis revealed that PR1 have the shortest LT50 and LT90 with 10.03 days and 14.69 days, respectively. Correlation analysis revealed a significant moderate negative correlation between tick size and mortality and not significant between germination rate and tick mortality. These findings emphasize the influence of tick size on tick mortality. Although no isolate achieved 100% mortality, PR1 was notably effective, killing the highest percentage of ticks quickly and significantly reducing egg production compared to the control and other isolates. Overall, this study underscores the potential of Malaysia-isolated M. anisopliae in the management of adult R. microplus, offering insights into alternative strategies for pest control in the livestock sector.
Association Vitamin D2 and PFAS among pregnant women from NHANES 2017-2018: A case Control Analysis
Authors: Ripon Rezaul Karim
Published: October 2024

Introduction: This study uses data from the 2017-2018 NHANES survey to evaluate how exposure to perfluoroalkyl substances (PFAS) affects vitamin D2 levels in pregnant women. PFAS are widely known for their environmental persistence and potential health risks, particularly during pregnancy, as they affect important biological functions such as the metabolism of vitamin D2, which is essential for bone health and immune function.
Methods: The study focused on pregnant women from the NHANES 2017-2018 cohort, using “comment code LBDVD2LC – 25OHD2” to classify vitamin D2 levels and different PFAS as exposure variables. Data analysis was carried out with R to address the complicated design of the NHANES survey. To explore associations, weighted descriptive statistics, bivariate analyzes and logistic regression were used.
Results: The analysis found that most participants had vitamin D2 levels below the detection limit. PFAS exposure and reduced vitamin D2 levels were remarkably correlated. A significant association was found between increased exposure to PFAS and decreased vitamin D2 levels (p values <0.001), indicating that exposed pregnant women have low vitamin D2 levels.
Conclusion: This study highlights the negative effects of PFAS exposure on vitamin D2 levels in pregnant women, helping to understand PFAS as an important risk factor during pregnancy. The goal of future studies should be to clarify specific biochemical interactions and suggest feasible public health plans to reduce this exposure.
Hydrothermal Synthesis of Tungsten Oxide Photo/electrocatalysts: Precursor-Driven Morphological Tailoring and Electrochemical Performance for Hydrogen Evolution and Oxygen Reduction Reaction Application
Authors: Sarma Rahul , Kakati Biraj Kumar
Published: October 2024

This research examines the effective use of two specific precursor i.e Hydrochloric acid and Oxalic acid used in the synthesis of Tungsten oxide (WO3). Catalytic reactions including Oxygen Reduction Reaction (ORR) and Hydrogen Evolution Reaction (HER) was investigated with the synthesised material. The morphological as well as electrochemical characteristics were studied using Field Emission Scanning Electron Microscope (FESEM), X-ray Diffraction (XRD), Energy-Dispersive X-ray spectroscopy (EDX), UV spectroscopy along with electrochemical analysis. It is being found that the WO3 synthesised with oxalic acid (WO3-ox) demonstrated in superior HER catalysis, whereas the other variant (WO3 with HCl (WO3-h)) showed better ORR performance. An optical bandgap of 2.638 eV was obtained for WO3-ox. Moreover, electrochemical analysis revealed an ORR peak at 0.52 V for WO3-h, in acidic media of electrolyte. As a result of which the two electrocatalyst were utilised in two different applications. WO3-ox was used for Methylene Blue (MB) degradation under the UV light and WO3-h was incorporated as a cathode catalyst for electricity generation and wastewater treatment in Microbial Fuel Cell (MFC). A degradation efficiency of 83.9% was attained in a span of 3 hours. On the other hand, MFC showed superior electrical power density of 209.72 mW/m2 with catalyst as compared to bare carbon cloth electrode (139.78 mW/m2). The chemical oxygen demand (COD) removal efficiency, which acts as a measure of wastewater treatment was 1.47 folds higher with the MFC having the catalyst. Thus, by tailored modulation of synthesised material with different precursor can lead to optimization of its features for various applications like degradation of methylene blue and microbial fuel cell.

Authors: Li Lili , Yao Huiping , Li Fei , Xu Qiuwen , Hua Jiali , Zhang Ying , Wu Jing
Published: October 2024

Objective This study aims to identify the potential classifications of sleep disturbances within the ICU nurse population, and to compare the between-group differences in demographic data and sleep characteristics.Methods Through convenience sampling, ICU nurses from three tertiary A-level hospitals in China were selected as research subjects from March to May 2024. A survey was conducted using a demographic data questionnaire, the PSQI scale, the DASS-21 scale, and the BPS scale, and the data on the sleep quality of ICU nurses was collected via electronic questionnaires. This research also utilized latent class analysis to examine the symptomatic traits of sleep quality in ICU nurses. Additionally, it applied univariate analysis and unordered multinomial logistic regression models to determine the factors influencing the various categories of their sleep quality.Results A total of 545 questionnaires were distributed, of which 522 were validly returned, yielding an effective response rate of 95.7%. Four potential sleep quality profiles were identified, including "high sleep quality - no sleeping pills," "medium sleep quality - low sleeping pills," "medium sleep quality - medium sleeping pills," and "low sleep quality - high sleeping pills," with proportions of 43.7%, 40.6%, 10.5%, and 5.2%, respectively. Unordered multinomial logistic regression analysis indicated that the number of night shifts per week, marital status, BPS scores, FSS scores, and DASS-21 scores were key factors affecting the sleep quality classification of ICU nurses(P < 0.05).Conclusion The sleep quality characteristics of ICU nurses are diverse and can be divided into four different categories. Therefore, nursing managers should be aware of this heterogeneity and take corresponding intervention measures based on the classification of nurses to ensure their sleep quality and promote psychological health.
“What other option did I have?” – The effect of conflict and displacement on child marriage and early childbearing among displaced Rohingya adolescents

Published: October 2024

Background. Humanitarian emergencies are postulated to increase rates of early marriage and early childbearing, as drivers of both are heightened or exacerbated in crisis settings. There is a critical need for research that explores the causal mechanisms that motivate family formation, i.e. the process from marriage into childbearing, and how this process is affected by conflict and displacement.
Objective. This paper aims to describe how displacement and living within a camp context has affected trends, norms, and drivers around family formation, focusing on the lived experience of female and male adolescents and young adults aged 15-24.
Methods. We coded and analyzed qualitative data from forty-nine in-depth interviews and sixteen focus group discussions conducted with Forcibly Displaced Myanmar Nationals aged 15-24 who arrived in Cox’s Bazar during or after October 2016.
Results. Participants agreed that rates of child marriage have increased post-conflict and displacement and generally attributed this increase to a variety of drivers, including fears around protection, socioeconomic need, lack of education and/or employment opportunities, and a perceived loosening of restrictions around legal age of marriage within camp. While some of these are pre-existing drivers exacerbated by conflict and displacement, others are new drivers that have developed as a result. The ways that adolescents experienced each driver were also highly gendered. Conversely, conflict and displacement had seemingly little effect on cultural expectations to demonstrate fecundity immediately after marriage. Finally, participants felt that adverse living conditions within camp have significantly lowered fertility intentions and have increased adoption of family planning.
Conclusions. Our results demonstrate that many Rohingya families currently view child marriage more as a practical tool to overcome challenges associated with being displaced, and early childbearing as an inevitable natural consequence of child marriage. The Bangladeshi government must ease restrictions on educational and livelihood opportunities for both adolescent girls and boys, who otherwise have no alternatives to child marriage, and few other opportunities to thrive and productively contribute to their communities.
Psychosexual Health’s Impact on NSSI：Chain Mediation of Adult Attachment and Social Supports
Authors: GAO Ping , ZHANG Yuqing , ZHAO Mei
Published: October 2024

This study utilizes the psychosexual health development (PSYCHOSEXUAL HEALTH), adult attachment scale (AAS), social supports rating scale (SSRS), and non-suicidal self-injury (NSSI) severity rating scales for clinicians’ questionnaires. The study explores the correlation between PSYCHOSEXUAL HEALTH and NSSI and the chained mediating roles of AAS and SSRS. We employed SPSS Windows software version 26.0 for relevant analysis and Amos for structural equation model analysis with Bootstrap mediating effects. The results indicate that PSYCHOSEXUAL HEALTH is closely correlated with AAS and SSRS, and can negatively predict NSSI behaviors. PSYCHOSEXUAL HEALTH can negatively predict NSSI under the mediating effect of SSRS. PSYCHOSEXUAL HEALTH can negatively predict NSSI through the mediating roles of AAS and SSRS. AAS has a full mediating effect, whereas SSRS has a partial mediating effect. Therefore, we conclude that PSYCHOSEXUAL HEALTH development is crucial to NSSI behaviors. Based on the conclusion, we discussed the future research direction to better develop secure AAS and high-quality SSRS through school education and guidance. This study provides a scientific theoretical basis for implementing PSYCHOSEXUAL HEALTH education and NSSI prevention efforts to reduce the occurrence rate and enhance school group interventions.

Published: October 2024

Response to the current situation of backward automation level, heavy labor intensity and high accident rate in underground coal mine auxiliary transportation system, the trackless auxiliary transportation robot system (MTATBOTS) is presented in the paper. The robot is specially designed for long-range, space-constrained and explosion-proof underground coal mine environment. With onboard perception and autopilot system, the robot can perform automated and unmanned subterranean material transportation. The paper proposes an integrated-odometry-based method to improve position estimation and mitigate location ambiguities for simultaneous localization and mapping (SLAM) in large-scale, GNSS-denied and perceptually-degraded subterranean transport roadway scenario. Additionally, the paper analyzes the robot dynamic model and presents the nonlinear control strategy for the robot to autonomously tack a planned trajectory based on the path-following error dynamic model. Finally, the proposed algorithm and control strategy are tested and validated in a virtual underground transport roadway environment relying on the simulation model of the robot system. The test result indicates that the proposed algorithm can obtain more accurate and robust robot odometry and better underground roadway mapping result compared with other SLAM solutions.

At the age of university students, it is important to accomplish the developmental tasks of adolescents. Furthermore, in addition to acquiring specialized knowledge and accomplishing developmental tasks, athletic colleges also require young athletes to be active. Therefore, we decided to investigate the use of a smartphone application, me-fullness® as an unprecedented method of support for female college students currently enrolled in athletic colleges. We conducted a psychological survey of female university students at the International Pacific University in Okayama, Japan, before and after one month of use of a me-fullness® app (N = 125) and a group of non-users (N = 85). The app-using group showed significant improvement in depressive symptoms, anxiety symptoms and stress scores as indicated by the Depression, Anxiety and Stress Scale − 21 Items (DASS-21), as well as insomnia, Premenstrual Syndrome (PMS) and resilience scores, while the non-app-using group showed improvement in anxiety and resilience (by Wilcoxon signed-rank test). This study suggests that use of the me-fullness app may have improved depression, stress, insomnia, and resilience. We hope that this study will lead to better college life and sports performance for female students in athletic universities and colleges.

Published: October 2024

Fruit color is a crucial trait for bell pepper. To investigate the mechanism of color formation, three bell pepper lines with different color (yellow, orange and red) were used as materials to conduct comprehensive targeted metabolomic and transcriptomic analyses. During the process of fruit development, 54 carotenoids metabolites were discovered, exhibiting unique accumulation patterns and notable variety specificity. The types and content of carotenoids in orange fruit (OM) were notably greater compared to the other two varieties. Red pigment (capsanthin and capsorubin) was specifically enriched in red fruit (RM), and yellow pigment (lutein and zeaxanthin) is the highest in yellow fruit (YM) and OM. Five modules positively correlated with carotenoid accumulation and one negative module was determined by weighted gene co-expression network analysis (WGCNA). Additionally, transcription factors (TFs) and hub genes related to carotenoid synthesis were predicted. By elucidating the regulation of 7 key carotenoid metabolites by 14 critical genes, we constructed a comprehensive carotenoid biosynthesis metabolic network that comprehensively explains the pigment changes observed in green and mature pepper fruit. Overall, the results not only provide important insights into carotenoid synthesis pathway, but also lay a solid base for revealing the mechanism of bell pepper color transformation.

Agricultural activities tend to produce a lot of waste in their operation. These wastes, if not properly disposed of, cause environmental pollution. This agricultural waste (biomass) can be utilized into valuable materials like rice husk ash (RHA) and biochar. Ordinary Portland Cement (OPC) is the primary binder in standard cementitious mixes and a significant contributor to CO2 emissions. This study investigates the utilization of RHA and biochar as supplementary cementitious materials to minimize the need for OPC. This research adopts pyrolysis and controlled combustion to convert rich husk (agricultural waste) to produce RHA and biochar. In order to establish RHA and Biochar's suitability as SCM, chemical composition techniques (X-Ray Diffraction analysis, X-Ray Fluorescence analysis, and Ultrasonic Pulse Velocity test) and mechanical performance testing (compressive strength tests of various mortar mixes with varied percentages (0%, 5%, 10%, and 15%) replacement of RHA and Biochar by weight of cement) were conducted. The findings showcased that partially replacing OPC with RHA and biochar in cementitious mixes improves mechanical performance and durability while maintaining a lower carbon footprint. Utilization of agricultural waste in cementitious materials encourages efficient circular economy principles as well as environmentally sustainable infrastructure. This study highlights how using bio renewable resources can lead to sustainable development.

Vallisneria americana is a submersed rooted macrophyte with ample geographic distribution in North America, which as a structured habitat, shelters high biodiversity of aquatic fauna and helps to sink Carbon. However, their populations have drastically decreased or disappeared in the free-flowing Usumacinta river system. Physico-chemical parameters in water, measurements of quantitative habitat complexity, and records of the fish collected were quantified in the unique path of V. americana. This patch of 4 m 2 registered a low average density (96 ∓ 48 stems/m 2), 61.7 ∓ 0.9 g ash free dry weight /m 2 of biomass, and 192 ∓ 42.3 masculine inflorescences/m 2. Six fish species of the Poecillid and Cichlid families were caught, with an average density of 19 ∓ 1.9 fish/m 2 , all of them less than 6.3 cm of standard length. This first record of V. americana in the transitional longitudinal zone (20-60 MASL) of the Usumacinta river system strengthens the relevance of the Wanhá Biosphere Reserve, as it was mainly decreed for their records of relictual inland of red mangrove populations, and high diversity of tropical swamp woody communities. Moreover, the American eelgrass patch represents a nursery area for at least six native fish of Poeciliids and Cichlids, which are the two more diverse fish families in Middle America. Moreover, Cichlid´s fishery is a relevant component to environmental sustainability.

The normal developmental and homeostatic roles of tissue resident macrophages are subverted in tumor-associated macrophages to promote tumor progression. Pro-tumoral macrophage activities include immune evasion and promotion of invasion and metastasis. We show that both activities are regulated by the myeloid Src family kinase HCK, which drives macrophage motility and invasive capacity. Loss of HCK reduced the growth of the aggressively invasive Py8119 mammary tumor by 70–80% while excessive HCK activity increased tumor growth. Consistent with a role for HCK in regulating macrophage invasiveness, plasma membrane-associated Src family kinase activity at the tumor margins was lost in the absence of HCK. Additionally, tumors from HCK-deficient hosts contained increased CD8+ T cell numbers and CD8+ T cell depletion reduced survival of tumor-bearing mice. However, CD8+ T cell-depleted HCK-deficient mice continued to show a significant survival advantage over CD8+ T cell-replete control mice, confirming a T cell-independent role for HCK in the promotion of tumor invasion and metastasis. Single cell RNA sequencing confirmed that macrophages comprised more than 40% of tumor mass associated with CSF-1 and IL-34 secretion by Py8119 cells and that loss of HCK activity did not affect macrophage recruitment. Tumor-associated macrophages were clustered into 5 subtypes, immunoregulatory (Folr2high), inflammatory (H2-Aahigh), interferon-primed, angiogenic and tissue resident, and their relative proportions were not affected by HCK activity. Thus, HCK regulates macrophage invasive capacity and cytotoxic T cell numbers but not macrophage numbers or their subtype distribution to drive Py8119 tumor growth.

In this study, the optimization of welding parameters, pore defects, microstructure and mechanical properties of Ti6Al4V alloy welded joints subjected to ultrasonic-assisted laser welding were studied. The optimal parameter combination and the most significant factor influencing the tensile strength of the joint were determined by three-factor and three-level orthogonal experiments with range and variance analysis methods. A control experiment was set up under the optimal parameters to reveal the reason of ultrasonic influence on joint strength from the pore defects and microstructure. The control test showed that the cavitation effect and stirring effect of ultrasonic could significantly improve the weld defects and microstructure. Compared with no ultrasonic, the porosity of the welded joint decreased from 3.06% to 0.08%, and the average grain size of prior-β and α' martensite were refined by 15.1% and 6.7% respectively under an ultrasonic power of 1000W. The ultrasonic vibration also contributed to the grain boundary transformation from low-angle to high-angle and significantly reduced the residual stress inside the joint. With the increase of ultrasonic power, the tensile strength increased by 4.37% and 8.38% respectively and the fracture mode changed from brittle-ductile mixed fracture to ductile fracture.

We compare the abundant prolate shaped galaxies reported in deep JWST surveys, with the predicted stellar appearance of young galaxies in detailed hydro-simulations of three main dark matter contenders: Cold (CDM), Wave/Fuzzy ($\psi$DM) and Warm Dark Matter (WDM). The observed galaxy images closely resemble the elongated stellar appearance of young galaxies predicted by $\psi$DM and WDM, during the first $\simeq$ 500Myr when material steadily accretes along smooth filaments. The dark matter halos of WDM and $\psi$DM also have pronounced, prolate elongation similar to the stars, indicating a shared, highly triaxial equilibrium. This is unlike CDM where the early stellar morphology is mainly spheroidal, formed from fragmented filaments with frequent merging, resulting in modest triaxiality. Quantitatively, the excess of prolate galaxies observed by JWST matches well WDM and $\psi$DM for particle masses of 1.4 keV and $2.5\times 10^{-22}$ eV respectively. For CDM, several visible subhalos are typically predicted to orbit within the virial radius of each galaxy, whereas sub-halos are absent for WDM and $\psi$DM, as early merging is rare. We also find that $\psi$DM is distinguishable from WDM by the form of the core, which is predicted to be smooth and centered for WDM but is a dense soliton for $\psi$DM and typically offset from the galaxy center by wave perturbations. We emphasise the long, smooth filaments of $\psi$DM and WDM may be detectable with JWST, traced by stars and gas with comoving lengths of 150kpc predicted at z$\simeq$10, depending on the DM particle mass.
Emotions in speaking up during rounds: A qualitative interview study of medical residents
Authors: Gribben Jeanie , Choi Justin J.
Published: October 2024

Speaking up during inpatient medical rounds involves medical trainees voicing ideas, concerns, or information when unprompted for the benefit of patient care and education. Medical residents encounter a unique set of considerations regarding the decision to speak up during rounds. However, little is known about the role of trainees’ emotions in speaking up in this context. The objective of this study was to explore the role of emotions in speaking up behaviours among medical residents during inpatient medical rounds. We conducted interviews with 21 medical residents inquiring about perspectives on speaking up. We developed a framework for classifying emotions, which consisted of valence (positive or negative), moral emotions (condemning, self-conscious, suffering, or praising), and non-moral emotions (fear, love, schadenfreude). Interview transcripts were deductively coded and analyzed to identify patterns of emotions and their drivers in the context of speaking up during rounds. Medical residents shared a range of positively- and negatively-valenced emotions in association with speaking up during rounds. We identified five types of emotions in speaking up during rounds that were commonly experienced by residents: praising emotions, self-conscious emotions, condemning emotions, suffering emotions, and fear. Specific drivers of these emotions were identified and classified into workplace, relational, patient-related, or personal factors. Ultimately, we found that medical residents experience both positive and negative emotions that influence speaking up behaviours during inpatient rounds. Further exploration into the role that emotions play in speaking up on inpatient medical rounds may provide valuable insights for medical education research and teaching practices.
