Published: January 2025

Abstract
The Shillong Plateau (SP) and adjoining regions are one of the world’s most seismically active regions and to conduct a thorough seismological investigation and improved seismic hazard assessment, an updated and unified earthquake catalog is a prerequisite. In the present study, we compiled a homogeneous declustered earthquake catalog for the SP and adjoining regions by utilizing updated earthquake data from various international and national databases and pertinent literature for the period 825–2024, which consists of 6877 earthquakes. Employing the generalized orthogonal regression, orthogonal distance regression, standard least square regression, and inverted standard least square regression methods, 30 empirical relations have been derived to achieve magnitude homogeneity. All the reported magnitudes are converted into moment magnitude (Mw) using the derived regression relations. Subsequently, the declustering of the compiled homogenous earthquake catalog has been carried out using three techniques to distinguish dependent and independent earthquakes. Three approaches are used to assess the completeness of the nondeclustered and declustered earthquakes in terms of time and magnitude. The compiled updated and unified catalog in the present study contains 6877 earthquakes of Mw≥3.5 for the period 825–2024 obtained out of a total of 19,499 earthquakes reported from all sources. The completeness periods of the GK74 declustered earthquake catalog obtained by the cumulative visual inspection method for different magnitudes range from 14 to 218 yr and by Stepp’s method, it ranges from 15 to 215 yr. The spatial distribution of the magnitude of completeness (Mc), cumulative a-value, and b-value of the GK74 declustered earthquake catalog varies from 4.71 to 4.99, 5.64 to 10.17, and 0.68 to 1.63, respectively. The compiled updated and unified earthquake catalog is expected to be an essential input for regional seismicity, earthquake hazard, seismotectonic, and seismic hazard analysis of the SP and adjoining region.

Relevance. The climatic conditions of the Primorsky Territory, the determining factors of which are its geographical location at the junction of the continent of Eurasia and the Pacific Ocean, are unique, which determines the main directions of breeding vegetable crops at the Primorskaya Vegetable Experimental Station – branch of the Federal State Budgetary Scientific Institution «Federal Scientific Vegetable Center» (PVES – branch of the FSBSI FSVC). The article provides an overview of the main achievements of the station's scientists' long-term work on tomato breeding for open ground and identifies the main tasks for further development of this area in the conditions of the south of the Russian Far East.Results. Based on the results of many years of research, the model of tomato variety of universal type for open ground was specified taking into account the requirements of the modern market of Primorsky Krai: ripeness group – medium-early or medium-ripening, short sprouting-flowering period; determinant plant, compact with medium or high foliage and medium-sized leaves (important for mechanized cultivation); brush – simple or intermediate; stalk – without articulation or with thickening (easy fruit detachment); fruit – of different shape, weight 60-100 g dry matter content not less than 5%, with uniform coloring without a spot at the stalk in milk ripeness and different coloring in biological ripeness, resistant to cracking, vertex rot, with high storability and transportability; resistance – to sudden temperature changes, soil overwatering, high temperatures and air humidity during the fruiting period, to diseases of various etiologies, primarily to Alternaria and Phytophthora. Since a significant factor in reducing the productivity of varieties are diseases (as a result of increasing aggressiveness and expansion of the species composition of pathogens), the priority at present is breeding for immunity. Within this framework, intensive search for valuable sources and creation of new source material based on hybridization, individual and family selection from the best varietal and hybrid populations is carried out. Among the achievements of breeding of PVES promising are varieties Fitilek and Echo (tolerant to Alternaria), varieties Odyssey, Patrokl and Summit (tolerant to Phytophthora), on the basis of which parental lines are created. The breeding process also involves the most adaptive open field varieties of FSVC selection and the source of group resistance to Alternaria and Phytophthora - variety Ottava 30.Conclusion. Creation of targeted breeding achievements will allow to expand the variety range and saturate the vegetable market of this economically important region of the south of the Far East Primorye with domestic varieties within the framework of the import substitution program.

Counterintuitive method improves yields of isotopically labeled proteins expressed in flask-cultured Escherichia coli
Authors: Treviño Miguel Ángel 
Published: January 2025

Abstract

NMR is a powerful tool for the structural and dynamic study of proteins. One of the necessary conditions for the study of these proteins is their isotopic labeling with 13C, 15N and sometimes 2H. One of the most widely used methods to obtain these labeled proteins is heterologous expression of the proteins in E. coli using 13C-D-glucose and 15NH4Cl as the sole nutrient sources. In recent years, the price of 13C-D-glucose has almost tripled, making it essential to develop labeling methods that are as cost effective as possible. In this work, different parameters were studied to achieve the most rational use of 13C-D-glucose, and an optimized method was developed to obtain labeled proteins with high labeling and low 13C-D-glucose consumption. Surprisingly, the optimized method is also simple and does not require monitoring of culture growth.
Shedding suppresses receptor-ligand trogocytosis to enhances long-term antitumor potential
Authors: Minagawa Atsutaka , Ishi Tomoko , Kaneko Shin 
Published: January 2025

Abstract

Trogocytosis is a curious phenomenon in which the rapid transfer of cell-membrane proteins between cells is induced by receptor-antigen ligation. In Chimeric antigen receptors therapy, the target antigen is transferred to T cells via trogocytosis, thereby decreasing the target density on tumor cells and abating the T cell activity. The result is tumor immune escape and T cell fratricide, two factors known to cause relapse after Chimeric antigen receptors therapy. Here we report receptor shedding as a mechanism to suppress trogocytosis. The shedding structure of Chimeric antigen receptors corresponded with the trogocytosis and long-term antitumor effect. This link between trogocytosis and shedding indicates a previously unknown form of communication between proximal cells.
Stranded assets in EU+UK agriculture during food system transformations

Published: January 2025

Abstract

A large-scale food system transformation is essential in mitigating a host of environmental crises, including climate change. Dietary shifts, particularly a reduction in animal-sourced foods (ASFs) in high-income countries, are a key pillar. These shifts risk stranding substantial ASF-related assets. ASF-focussed assets represent 78% of EU27+UK fixed agricultural assets, with €158 billion linked to livestock and €100 billion to feed production. We estimate that reductions in ASFs of 9.5%, 60%, and 100% in dietary transitions could strand 18%, 50%, and 77% of these assets, respectively. We find that there is generally sufficient time to depreciate and phase-out assets, offering a pathway for limiting stranded assets. Investors should account for potential stranding risks in financial modelling, alongside climate-related risks. Given food producers’ high exposure to the risks of asset stranding – with potential cascading effects throughout the supply chain – integrated policy support is essential in ensuring a just, effective transition.
Electromagnetic performance analysis of coaxial magnetic gear with three rotors featuring a monotonic magnetic ring and dual modulation enhancement effect
Authors: Wang Jungang , Zhang Chuntao , Mo Ruina , Ren Jiwen , Li Song 
Published: January 2025

Abstract

The strength of magnetic field modulation effect of coaxial magnetic gears is a key factor to measure the transmission performance of coaxial magnetic gears. Although the dual modulation coaxial magnetic gears with double modulating magnetic rings can effectively enhance the magnetic field modulation effect, there are still the problems of low torque density and serious magnetic leakage loss. In order to address the above problems, this paper proposes a three-rotor single-regulating ring dual-modulated coaxial magnetic gear that simultaneously adopts the “sum modulation effect” and “differential modulation effect”, and analyzes its working principle and the structure of multiple magnetic circuits that inhibit magnetic saturation; establishes the corresponding finite element model and analyzes its electromagnetic performance. The finite element model is established and its electromagnetic performance is simulated and analyzed; the results show that the modulation effect of the single-regulating magnetic ring double-modulated coaxial magnetic gear is strong, but the steady-state torque fluctuation of the outer rotor is large. To address this problem, Halbach magnetization is used to suppress the large fluctuations in the torque of the outer rotor, and the torque fluctuation of the outer rotor is reduced by 5.67% after the improvement. The single-modulating magnetic ring dual modulation coaxial three-rotor magnetic gear proposed in this paper enhances the magnetic field modulation effect while suppressing the magnetic saturation phenomenon, improves the utilization rate of permanent magnets, reduces the amount of modulating ring, and provides a reference for the research of single-modulating magnetic ring dual modulation coaxial magnetic gear.
TLR-5 influences T cell activity: implications for development of Type 1 Diabetes

Published: January 2025

Abstract

In mammalian and human life, one of the most important problems is to choose the best defence against microorganisms. Innate cells are good against bacteria, and T cells against virus mainly because of antibody production via T helper and B lymphocytes. Toll-like receptor 5 (TLR-5) is a regulator of this choice; when it is highly expressed, T cells are inhibited, and innate cells are favored. In activated pancreatic beta cells, TLR-5 has been found highly expressed and may therefore be protected from T cell destruction e.g., during pregnancy. We investigated mRNA from islets of Langerhans from newly diagnosed T1D patients for TLR-5. Also, we examined for polymorphisms between TLR-5, metabolic parameters, and Type 1 Diabetes (T1D). mRNA for TLR-5 was downregulated by one-third in the newly diagnosed T1D patients compared to controls. Regarding polymorphisms, two associations were found between TLR-5 and monocytes which are cells from the innate immune system. Also, a significant polymorphism was seen concerning TLR-5 and T1D. T cells are important for autoimmune diseases including T1D. In the present study we find low values of mRNA of TLR-5 which enhance T cells. We hope that the findings mentioned in this article may be influential for the understanding of how T1D develops.
LLM-based Intermediate Interpretations for Predicting Nurse Stress and Its Causes from Step Count Data
Authors: Fukazawa Yusuke , Kodaka Megumi 
Published: January 2025

Abstract

Purpose: This study aims to propose and evaluate a hybrid approach that combines Large Language Model (LLM)-based interpretation with machine learning (ML)-based prediction to estimate stress levels and their causes from step count data. The research addresses the gap in existing datasets that lack information on the underlying causes of stress.
Methods: Step count data, stress assessments (QIDS score), and stress causes were collected from 30 nurses using six questionnaires rated on a 4-point Likert scale over eight days within one month. Two tasks were designed for evaluation: (1) assessing the contribution of intermediate interpretations to the accuracy of stress presence estimation and (2) validating the use of intermediate interpretations for identifying stress causes. BERT models with and without intermediate stress interpretations were compared, alongside a prompt-based approach.
Results: In the first task, BERT with intermediate interpretations achieved the highest accuracy of 0.74, outperforming BERT using raw step count data (0.63) and distance data (0.59). In the second task, the same model achieved a ranking accuracy of 0.60, compared to 0.56 for raw step count data. Significant correlations were identified between stress levels and work-related factors such as ''workplace relationships,'' ''busy work,'' ''heavy responsibilities,'' and ''lack of time off.''
Conclusion: The findings demonstrate that incorporating LLM-based intermediate interpretations enhances the accuracy of stress prediction and facilitates the identification of key stress causes. This hybrid approach offers a promising framework for analyzing mental health using sensor data.

Published: January 2025

Abstract

Introduction: Hirschsprung's disease, a congenital disorder, is characterized by the absence of ganglion cells in the Meissner's plexus of the submucosa and Auerbach's plexus of the muscularis. Notably, late presentation is uncommon, with 95% of cases being diagnosed in infants younger than one year of age.
Case presentation: 15-year-old Black female patient presented to our hospital with the compliant of failure to pass feces of 5 days duration associated with abdominal distention. From an early age, she experienced persistent constipation and abdominal distention, leading to multiple admissions to local health centers for enema treatment. Oral laxatives were also prescribed, but they only provided temporary relief of her symptoms. Abdominal x-ray showed significantly dilated bowel loops with fecal loading. Barium enema showed a transition zone at the proximal one-third of the rectum with reversed rectosigmoid ratio. Rectal biopsy confirmed the diagnosis. Decompressive colostomy was done followed by soave pullthrough 3 months later.
Conclusion: Adolescent patients with a history of childhood-onset constipation should be evaluated for the possibility of undiagnosed Hirschsprung's disease. Treating this condition can significantly enhance the patient's quality of life.
