Prolongations of integral domains
Journal of Algebra, 1985 The motivation for this rather extensive and complicated paper is derived from the purely algebraic approach to the theory of overdetermined systems of partial differential equations. A system of (algebraic) differential equations represents a set of elements \(F_ 1,F_ 2,...,F_ n\) of a polynomial ring \(P=k[\delta^ py_ j: p\in {\mathbb{N}}^ m, j=1,...,

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Secondary hyperparathyroidism (SHPT) is a common complication in patients receiving maintenance dialysis, driven by calcium and phosphate metabolism disturbances. Calcimimetics are central to the management of SHPT by enhancing calcium‐sensing receptor sensitivity and reducing parathyroid hormone secretion.

The Jump Problem for Mixed-Type Equations with Defects on the Type Change Line
Boundary Value Problems, 2010 The jump problem and problems with defects on the type change line for model mixed-type equations in the mixed domains are investigated. The explicit solutions of the jump problem are obtained by the method of integral equations and by the Fourier ...

On variational formulations of inner boundary value problems for infinite systems of elliptic equations of special kind [PDF]
Математичні Студії, 2012 We consider boundary value problems for infinite triangular systems of elliptic equations with variable coefficients in 3d Lipschitz domains. Variational formulations of Dirichlet, Neumann and Robin problems are received and their well posedness in ...

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Fixed Points for Pseudocontractive Mappings on Unbounded Domains
Fixed Point Theory and Applications, 2010 We give some fixed point results for pseudocontractive mappings on nonbounded domains which allow us to obtain generalizations of recent fixed point theorems of Penot, Isac, and Németh. An application to integral equations is given.

Boundary value problems on part of a level-n Sierpinski gasket
Boundary Value Problems, 2017 We study the boundary value problems for the Laplacian on a sequence of domains constructed by cutting level-n Sierpinski gaskets properly. Under proper assumptions on these domains, we manage to give an explicit Poisson integral formula to obtain a ...

Domain wall dynamics of the Ising chains in a transverse field
, 2003 We show that the dynamics of an Ising spin chain in a transverse field conserves the number of domains (strings of down spins in an up-spin background) at discrete times. This enables the determination of the eigenfunctions of the time-evolution operator,
