, 2007 本論文主要在探討和應用無網格基本解法求解赫姆霍茲、擴散及柏格斯方程式。首先是波導管問題之赫姆霍茲方程式。同邊界元素法僅需邊界點和源點，但無需點與點間的關係和數值積分，即可以基本解法結合奇異值分解法求得波導管的截止波數，進而求得模態圖，成功模擬橢圓波導管問題，此法可有效省下記憶體空間。其次，求解半無窮域之史托克斯第一問題及第二問題。僅有唯一受制邊界條件，基本解法無受限於計算域形式，可成功求解半無窮域和外域問題。以基本解法求解非穩態問題，直接應用具時間項的基本解，不需拉普拉斯轉換也不需要時間微分項的離散 ...

A Regularized Method of Fundamental Solutions Without Desingularization
, 2013 Some regularized versions of the Method of Fundamental Solutions are investigated. The problem of singularity of the applied method is circumvented in various ways using truncated or modified fundamental solutions, or higher order fundamental solutions ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

MathematicsBased on a new general solution, we derive three skew-symmetric variants of the method of fundamental solutions (MFS) for solving the three-dimensional Stokes equations: the symmetric/skew-symmetric MFS (SSMFS), the separated MFS (SeMFS) as an extension ...

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Asymptotic stability of the fundamental solution method
Journal of Computational and Applied Mathematics, 1991 The Dirichlet problem for the Laplace equation is considered in the circle \(| x|\rho\). The coefficients \(c_ k\) are found from the collocation system \(Ac=g\). An asymptotic estimate for the vector \(u=\Lambda c\) of the type \(\| u\| \leq Kn\| g\|\) is proved with norms related to the space \(R^ n\).

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
