Surfaces of general type with p_g=q=2

, 2013
這篇文章主要是在探討代數曲面的分類理論。特別地我們考慮虧格數與非正則數均為二的一般形曲面，到目前為止，對於這一種曲面的分類還是不完全的。我所做的事是在於真正構造出實際的例子。在這篇文章中我們考慮兩種構造曲面的方法。第一種做法是考慮與兩條曲線乘積同源的曲面。這一類的曲面有一些好的性質，所以在討論上是相對容易的。佩納吉尼做出了一張列表，把這類的曲面完全分類完畢了。第二種做法是去考慮在阿貝爾的曲面上的有限覆蓋。陳榮凱與黑肯利用阿貝爾曲面上的三次覆蓋造出了一個例子。我依循他們的做法 ...

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Surfaces of general type with maximal Picard number near the Noether line

The first published non-trivial examples of algebraic surfaces of general type with maximal Picard number are due to Persson, who constructed surfaces with maximal Picard number on the Noether line $K^2=2\chi-6$ for every admissible pair $(K^2,\chi ...

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

Advanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...
