Triton, a high-level Python-like language designed for building efficient GPU kernels, is widely adopted in deep learning frameworks due to its portability, flexibility, and accessibility. However, programming parallel optimization still require considerable trial error from Triton developers. Despite advances large models (LLMs) conventional code generation, these struggle generate accurate, performance-optimized code, as they lack awareness of specifications the complexities programming....
The power transformer is a critical primary device in the grid, and verification of its winding mechanical stability paramount importance ensuring safe stable operation grid. In conventional numerical calculation methods for verifying windings, influence temperature variations at hot spots on has not been taken into account. reality, factors such as transformer’s operating load rate, ambient temperature, duration short-circuit fault currents passing through will affect margin windings. Under...
Introduction Bacterial wilt (BW) caused by Ralstonia pseudosolanacearum is a devastating soil-borne disease. Bacteriophages are important biocontrol resources that rapidly and specifically lyse host bacteria, showing good application potential in agricultural production. Methods This study isolated nine phages (YL1–YL9) and, using range pot experiments, identified two broader (YL1 YL4) higher control efficacy (YL2 YL3), which were combined to obtain five cocktails (BPC-1–BPC-5). Results Pot...
Isomeric yield ratios (IYR) are an important tool to study the angular momentum generation in nuclear fission and investigate possible influence on spin of compound nucleus formed a reaction. One method measure IYR is use Phase-Imaging Ion-Cyclotron-Resonance (PI-ICR) technique. The PI-ICR direct ion counting technique based spatial separation ions trapped circular motion their projection onto position-sensitive detector. Here analysis routine presented for images produced 21 products by 32...
In this study, we applied the Total Monte Carlo (TMC) methodology in de-excitation simulations of primary fission fragments (FF) using TALYS code. The goal was to develop and optimise a benchmark initial model assumptions on mass yield distributions, excitation energy sharing angular momentum population. study performed thermal neutron induced 239 Pu(n th ,f). work aimed at evaluating deficiencies parameter sensitivities. We systematically varied input data by generating 5000 random files...
The origin of the large angular momenta observed for fission fragments is still a question under discussion.

Surface-enhanced Raman spectroscopy (SERS) is a powerful tool for label-free chemical analysis. The emergence of nonmetallic materials as SERS substrates, offering signal enhancements, presents an exciting direction achieving reproducible and biocompatible SERS, challenge with traditional metallic substrates. Despite the potential, realm particularly nanoparticles, remains largely untapped. Here, we present defect-engineered coordination compounds (DECCs) based on Prussian blue analogues...
