On Solution of Regular Singular Ordinary Boundary Value Problem

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2017
 This paper devoted to the analysis of regular singular boundary value problems for ordinary differential equations with a singularity of the different kind , we propose semi - analytic technique using two point osculatory interpolation to construct ...

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

open access: yesFEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

An efficient spectral method for nonlinear Volterra integro-differential equations with weakly singular kernels

open access: yesMathematical Modelling and Analysis
For Volterra integro-differential equations (VIDEs) with weakly singular kernels, their solutions are singular at the initial time. This property brings a great challenge to traditional numerical methods. Here, we investigate the numerical approximation

Overexpression of CDT1 inhibits cell cycle progression at S phase by interacting with the mini‐chromosome maintenance complex and causes DNA damage

open access: yesFEBS Open Bio, EarlyView.
CDT1 is an essential protein for DNA replication licensing that loads the MCM complex, the eukaryotic replicative DNA helicase, onto replication origins. Overexpression of CDT1 induces cell cycle arrest at the S phase. Here we showed CDT1 inhibits the progression of replication forks by interacting with the MCM complex, leading to the stalling and ...

The Singularities of the Solutions of the Cauchy Problem

open access: yesPublications of the Research Institute for Mathematical Sciences, 1969
This paper is concerned with the Cauchy problem of linear partial differential equation with holomorphic coefficients in complex domain. The Cauchy-Kowalewski theorem asserts that locally there exists a unique holomorphic solution of the Cauchy problem provided that the initial surface is non-character istic and the initial data are holomorphic.

A general model for analysis of linear and hyperbolic enzyme inhibition mechanisms

open access: yesFEBS Open Bio, EarlyView.
We developed a general enzyme kinetic model that integrates these six basic inhibition mechanism onto a single one. From this model, we deduced a general enzyme kinetic equation that through modulation of simple parameters, γ (the relative inhibitor affinity for two binding sites) and β (the reactivity of the enzyme–substrate–inhibitor complex), is ...
