The Dispersion Rule of Fragments about the Asymmetric Shell
Shock and Vibration, 2017 In order to obtain the dispersion rule of fragments about the asymmetric shell subjected to internal blast loading, two different cross section structures, concave-shaped and convex-shaped, were carried out by experimental and numerical methods.

Advanced Science, EarlyView.Interpretable machine learning reveals how composition and processing govern the formation and microstructural burden of Fe‐rich intermetallic compounds in recycled Al–Si–Fe–Mn alloys. By separating morphology selection from morphology‐conditioned burden partitioning, this framework shows that identical Fe contents can yield different intermetallic ...

logcondens: Computations Related to Univariate Log-Concave Density Estimation
Maximum likelihood estimation of a log-concave density has attracted considerable attention over the last few years. Several algorithms have been proposed to estimate such a density. Two of those algorithms, an iterative convex minorant and an active set

Triple‐Mode Ferroelectric Thin‐Film Transistor for Hybrid Electrical–Optical Reservoir Computing
Advanced Science, EarlyView.A triple‐mode ferroelectric thin‐film transistor is developed by integrating Si3N4/HZO/IGZO layers to realize three independent memory modes: electric long‐term, electric short‐term, and optical short‐term. This single‐device architecture functions as both a reservoir and readout layer, achieving 92.43% MNIST accuracy. It offers a fully hardware‐based,

Wavefront Line‐Scan Imaging Via a Single‐Pixel Detector
Advanced Science, EarlyView.We propose and demonstrate a wavefront line‐scan imaging paradigm that integrates 1D spatial light modulation with single‐pixel detection. Benefiting from 1D modulation, not only is the imaging speed improved, but also the storage of modulation patterns is reduced by several orders of magnitude.

RESEARCH ON THE CALCULATION MODEL OF DENT WITHOUT CONCAVE ANGLE ON OIL AND GAS PIPELINE
Jixie qiangdu, 2017 The most common type of pipe mechanical damage is dent defect,which is a major cause of leading to pipeline fatigue rupture. For further research on the security of the pipelines,it is necessary to establish a calculation model serving actual conditions.
