Effect of Current Density on Structure and Hardness of the MAO Film on 7N01 Aluminum Alloy Surface for Water Pump by WEI Si-yuan, LIU Zhi-ying

“…In order to improve performance of the MAO film on 7N01 aluminum alloy for water pump, the oxide film was prepared in an electrolyte containing graphene by controlling different micro-arc oxidation current density, and its structure and properties were analyzed as well. Results showed that thicker oxide film could be prepared under higher current density, and the film thickness and current density had an obvious linear variation trend. …”

Lagrangian flow measurements and observations of the 2015 Chilean tsunami in Ventura, CA by Nikos Kalligeris, Vassilios Skanavis, Sasan Tavakkol, Aykut Ayca, Hoda El Safty, Patrick Lynett, Costas Synolakis

“…From the maps of the flow field, we find that a tsunami with a near‐shore amplitude of 30 cm at 6 m depth produced unexpectedly large currents up to 1.5 m/s, which is a fourfold increase over what simple linear scaling would suggest. Coherent turbulent structures appear throughout the event, across a wide range of scales, often generating the greatest local currents.…”

Lumbar and pelvic CT image segmentation based on cross-scale feature fusion and linear self-attention mechanism by Chaofan Li, Liping Chen, Qiong Liu, Jinnan Teng

“…However, conventional CT imaging poses significant challenges due to the low contrast of sacral and bilateral hip tissues and the complex and highly similar intervertebral space structures within the lumbar spine. To address these challenges, we propose a general-purpose segmentation network that integrates a cross-scale feature fusion strategy with a linear self-attention mechanism. …”

A Simple Algorithm for Finding a Non-negative Basic Solution of a System of Linear Algebraic Equations by Gleb D. Stepanov

“…This article describes an algorithm for obtaining a non-negative basic solution of a system of linear algebraic equations. This problem, which undoubtedly has an independent interest, in particular, is the most time-consuming part of the famous simplex method for solving linear programming problems.Unlike the artificial basis Orden’s method used in the classical simplex method, the proposed algorithm does not attract artificial variables and economically consumes computational resources.The algorithm consists of two stages, each of which is based on Gaussian exceptions. …”
