On an integral equation with a bessel function kernel
Journal of Integral Equations and Applications, 1988 The author obtains the solution of the integral equation \(g(x)=\int^{\infty}_{0}J^ 2_ x(y)f(y)dy,\) where g(x) is a known function, \(J_ x(y)\) is the Bessel function of order x and f(y) is the unknown function. The solution obtained is: \[ f(y)=y\int^{\infty}_{0}\tau J_ 0(y\tau)\{\int^{\infty}_{0}G(x)\cos xt dx\}d\tau,\quad y\geq 0, \] where \(\tau ...

Error Estimation for Approximate Solutions of Delay Volterra Integral Equations
, 2019 This work is related to inequalities in the approximation theory. Mainly, we study numerical solutions of delay Volterra integral equations by using a collocation method based on sigmoidal function approximation. Error estimation and convergence analysis

Molecular Oncology, EarlyView.Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Stochastics integral equations with respect to semimartingales [PDF]
Stochastic integral equations were first developed by mathematicians as a tool for the explicit construction of the paths of diffusion processes for given coefficients of drift and diffusion. Since many physical, engineering, biological as well as social

Nuclear pore links Fob1‐dependent rDNA damage relocation to lifespan control
FEBS Open Bio, EarlyView.Damaged rDNA accumulates at a specific perinuclear interface that couples nucleolar escape with nuclear envelope association. Nuclear pores at this site help inhibit Fob1‐induced rDNA instability. This spatial organization of damage handling supports a functional link between nuclear architecture, rDNA stability, and replicative lifespan in yeast.

Distributional and entire solutions of ordinary differential and functional differential equations
International Journal of Mathematics and Mathematical Sciences, 1983 A brief survey of recent results on distributional and entire solutions of ordinary differential equations (ODE) and functional differential equations (FDE) is given. Emphasis is made on linear equations with polynomial coefficients.

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains
FEBS Open Bio, EarlyView.The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.
