An $S_3$ Model for Lepton Mass Matrices with Nearly Minimal Texture

, 2012
We propose a simple extension of the electroweak standard model based on the discrete $S_3$ symmetry that is capable of realizing a nearly minimal Fritzsch-type texture for the Dirac mass matrices of both charged leptons and neutrinos.

Texture Feature Extraction Methods: A Survey [PDF]

IEEE Access, 2019
Texture analysis is used in a very broad range of fields and applications, from texture classification (e.g., for remote sensing) to segmentation (e.g., in biomedical imaging), passing through image synthesis or pattern recognition (e.g., for image inpainting).

Incorporation of Selenium into Sol–Gel‐Derived Bioactive Glass: Influence on Glass Structure, Bioactivity, and its Selective Cytotoxicity

Advanced Engineering Materials, EarlyView.
Selenium was incorporated into a sol–gel‐derived bioactive glass to enable sustained therapeutic ion release. The selenium‐containing glass preserved bioactivity while selectively inducing cytotoxicity in osteosarcoma cells and maintaining osteoblastic viability.

结合纹理和形态学特征的高分遥感影像建筑物震害信息提取

Dizhen xuebao, 2019
为提高震害信息获取时效性，对基于我国国产高分遥感影像的建筑物震害信息提取方法进行深入研究，本文以2017年5月11日新疆塔县MS5.5地震为例，利用该地震前后极灾区高分遥感影像，利用结合纹理和形态学特征的方法进行了建筑物震害信息提取，通过变化检测分析获取了极灾区建筑物震害信息，并与基于像元级和基于目标级的信息提取结果进行对比，采用震后无人机影像目视解译结果对本文结果进行了精度验证。结果表明：通过缩减研究区范围可大力提高数据提取精度和速度；运用灰度共生矩阵、二值化、数学形态学等方法对影像进行迭代运算 ...

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.
