Promoting the Mathematization of Physics: Hermann Minkowski's Draft Presentations of His 1908 “Grundgleichungen” Paper

open access: yesBerichte zur Wissenschaftsgeschichte, EarlyView.
I present and discuss two drafts of remarks prepared by the mathematician Hermann Minkowski (1864–1909). They were composed in December 1907 while preparing his paper on the “Basic Equations of Electromagnetic Processes in Moving Bodies” for publication in the Proceedings of the Göttingen Academy of Sciences.

AIF1+CSF1R+ MSCs, induced by TNF‐α, act to generate an inflammatory microenvironment and promote hepatocarcinogenesis

open access: yesHepatology, EarlyView., 2022
Mesenchymal stem cells subset, educated by TNF‐α, are involved to generate inflammatory microenvironment and promote hepatocarcinogenesis Abstract Background and Aims Increasing evidence suggests that mesenchymal stem cells (MSCs) home to injured local tissues and the tumor microenvironment in the liver.

Structural Shape Optimization Based on Multi-Patch Weakly Singular IGABEM and Particle Swarm Optimization Algorithm in Two-Dimensional Elastostatics

open access: yesMathematics
In this paper, a multi-patch weakly singular isogeometric boundary element method (WSIGABEM) for two-dimensional elastostatics is proposed. Since the method is based on the weakly singular boundary integral equation, quadrature techniques, dedicated to ...

Asymmetric Dialysis: Truly Unified and Simultaneous Single‐Pass Concentration and Buffer Exchange

open access: yesBiotechnology and Bioengineering, EarlyView.
Asymmetric dialysis, a novel one‐step continuous process combining ultrafiltration and diafiltration, achieves high product concentrations (up to 200 g/L) with low pressures and reduces buffer consumption by 75% compared to conventional methods. This sustainable, low‐cost technology demonstrates significant potential for integration into continuous ...

A Collocation Numerical Method for Highly Oscillatory Algebraic Singular Volterra Integral Equations

open access: yesFractal and Fractional
The highly oscillatory algebraic singular Volterra integral equations cannot be solved directly. A collocation numerical method is proposed to overcome the difficulty created by the highly oscillatory algebraic singular kernel.

Mitochondria‐endoplasmic reticulum organelle glue as maturation promoter for origination/dimensional dual‐cross cardiomyocytes

open access: yesBMEMat, EarlyView.
Mitochondria‐endoplasmic reticulum contact sites (MERCS) are areas where the mitochondria and endoplasmic reticulum closely interact. In this study, we utilize synthetic organelle glues to artificially engineer MERCS for regulating cardiomyocyte development, through which the immature and chemo‐plasticity issues of undifferentiated cells are addressed.

A Pseudospectral Algorithm for Solving Multipantograph Delay Systems on a Semi-Infinite Interval Using Legendre Rational Functions

open access: yesAbstract and Applied Analysis, 2014
A new Legendre rational pseudospectral scheme is proposed and developed for solving numerically systems of linear and nonlinear multipantograph equations on a semi-infinite interval. A Legendre rational collocation method based on Legendre rational-Gauss
