Abstract This study addresses the optimization of automated yarn handling in textile manufacturing by examining the related suction process through a combined numerical and experimental approach. In particular, a three-dimensional model of the suction nozzle was coupled with an equivalent linear-elastic beam representation of the yarn, and a Fluent–IDW–Abaqus weakly coupled fluid–structure interaction (FSI) framework was employed to capture the yarn’s release and dynamic response under negative-pressure suction. High-speed imaging experiments validated the simulations, demonstrating excellent agreement in displacements and velocities. According to the results, increasing the initial suction pressure from −0.04 MPa to −0.06 MPa More >

Abstract Background: Transcatheter closure of perimembranous ventricular septal defects (pmVSDs) with Lifetech™ Konar-Multifunctional Occluder (MFO) has demonstrated high procedural success and safety. However, long-term complications due to valve–device interaction are rarely reported. We describe a pediatric patient who developed progressive right ventricular outflow tract (RVOT) obstruction and severe tricuspid regurgitation 20 months after MFO closure, highlighting mechanisms, management, and outcomes. Case Description: A 13-year-old girl underwent successful MFO closure of a 6-mm pmVSD. Early follow-up showed trivial tricuspid regurgitation and mild subpulmonic stenosis. Pre-procedural imaging revealed right ventricular hypertrophy caused by long-standing jet-related turbulence from the pmVSD, with… More >

Abstract Enhancing the strength of nanotwinned aluminum (Al) is essential for the development of next-generation high-end chip technology. To better understand the detwinning behavior of nanotwinned Al under conditions with no resolved shear stress acting on the twin boundaries, we conducted molecular dynamics simulations of uniaxial tensile deformation in nanotwinned single-crystal Al at room temperature. Detwinning is observed only when the twin boundary spacing is 7.01 Å. At larger spacings, twin boundaries remain parallel to the loading direction, with no rotation or bending, indicating negligible migration. Detwinning is triggered by localized stress from dislocation interactions, with More >

Abstract Deep shale gas reservoirs in the southern Sichuan Basin are typically characterized by significant horizontal stress anisotropy (expressed as stress difference), variable brittleness–ductility in rock mechanics, and strong heterogeneity. These complex geomechanical conditions lead to pronounced differences in hydraulic fracturing outcomes among wells and sections. To investigate hydraulic fracture propagation and fracturing fluid injection behavior under varying geomechanical settings, true triaxial physical simulation tests were performed on 400 × 400 × 400 mm artificial rock samples. The samples were designed with different media properties based on similarity criteria. A sensitivity analysis was conducted to assess… More >

Abstract In order to explore the effects of CaO, lignite dust and sawdust on the drying characteristics of municipal sludge at different concentrations, a three-factor three-level regression experiment was carried out based on the results of thermogravimetric experiment and single factor experiment. By fitting three common mathematical models, the Page model with the highest fitting degree was selected to determine the most suitable mathematical model to describe the municipal sludge drying process. In addition, the Box-Behnken design principle in the response surface method was used to analyze the interaction of three factors on the drying characteristics… More >

Abstract Keystone taxa are critical for microbial community homeostasis and ecological niche interactions. However, the functions and genomic traits of endophytic keystone fungi in plant tissues remain unclear. Via network analysis, this study identified keystone fungi Plectosphaerella (Plec) and Cladosporium (Clad) in roots/leaves of medicinal Panax plants (P. ginseng, P. quinquefolius, P. notoginseng). Both correlated strongly positively with ginsenoside Rd content in respective tissues (ρ > 0.6, p < 0.001). Co-cultivation confirmed their ability to convert ginsenoside Rb1 to Rd, linked to β-glucosidase activity. Whole-genome sequencing/assembly/evolutionary analysis of the two strains elucidated genomic features for their keystone roles and saponin biotransformation. More > Graphic Abstract

Abstract Mammalian fertilization involves the migration of spermatozoa through the female reproductive system. Early embryonic development is a consequence of several steps and signaling pathways being activated, as well as biochemical and morphological modifications of spermatozoa that enable them to penetrate the membrane of mature oocytes.
There are some crucial steps known to clearly explain the process of fertilization, starting with hyperactivation of spermatozoa, mutual recognition, and binding of gametes mediated by receptors located on the surface membranes of both gametes. The final step is followed by oocyte activation, which is primarily triggered via sperm-derived factors, inducing a More >

Abstract Interactions between many (initially separate) quantum systems raise the question on how to prepare and how to compute the measurable results of their interaction. When one prepares each system individually and let them interact, one has to tensor multiply their density matrices and apply Hamiltonians on the composite system (i.e., the system which includes all the interacting systems) for definite time intervals. Evaluating the final state of one of the systems after multiple consecutive interactions requires tracing all other systems out of the composite system, which may grow to immense dimensions. For computational efficiency during… More >

Abstract Globally, mealtimes provide key insights into cultural and social values and practices. We examine mealtime environments and eating practices in two different African settings using quantitative observational and questionnaire data. Participating families (N = 80) were recruited from two rural locations in Zambia and Kenya. Results following descriptive analysis showed that meals are typically taken as a family in a sociable context, providing opportunities to nurture children’s positive behaviours. In both communities, mothers (71.25%) were most likely to be present and typically prepared meals and provided the food. We observed a few distractions being used… More >

Abstract This study presents an implicit multiphysics coupling method integrating Computational Fluid Dynamics (CFD), the Multiphase Particle-in-Cell (MPPIC) model, and the Finite Element Method (FEM), implemented with OpenFOAM, CalculiX, and preCICE to simulate fluid-particle-structure interactions with large deformations. Mesh motion in the fluid field is handled using the radial basis function (RBF) method. The particle phase is modeled by MPPIC, where fluid-particle interaction is described through momentum exchange, and inter-particle collisions are characterized by collision stress. The structural field is solved by nonlinear FEM to capture large deformations induced by geometric nonlinearity. Coupling among fields is More >
