On a Functional-Equation of A. Hurwitz
Advances in Mathematics, 1995 The paper deals with the equation \((*)\) \(G'(z) = 2 \pi ie^{2 \pi iz} G(z + 1)\) and its adjoint equation \(F'(z) = - 2 \pi ie^{2 \pi iz} F(z - 1)\) in the complex domain. It is shown that \(G_ 0(z) = \int e^{-2 \pi iuz + \pi iu^ 2} \Gamma (u) du\) and \(F_ 0(z) = \int e^{2 \pi izu - \pi iu^ 2} \Gamma^{-1} (1 + u) du\) with integration over suitable ...

Nontrivial Solutions of Systems of Perturbed Hammerstein Integral Equations with Functional Terms
, 2021 We discuss the solvability of a fairly general class of systems of perturbed Hammerstein integral equations with functional terms that depend on several parameters.

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Stabilisation of hybrid stochastic differential equations by delay feedback control
, 2008 This paper is concerned with the exponential mean-square stabilisation of hybrid stochastic differential equations (also known as stochastic dierential equations with Markovian switching) by delay feedback controls.

Controllability of Second Order Functional Random Differential Equations with Delay
, 2022 In this article, we study some existence and controllability results for two classes of second order functional differential equations with delay and random effects. To begin, we employ a random fixed point theorem with a stochastic domain to demonstrate

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

On the associativity functional equation [PDF]
Fuzzy Sets and Systems, 2000 The author describes the class of continuous, nondecreasing, associative functions \(M:[a,b]^2 \to[a,b]\) such that \(M(a,a)=a\) and \(M(b,b)=b\), where \([a,b]\) is a bounded closed real interval. To this end the author surveys many known results of J. Aczél, C. H. Ling, B. Schweizer, A. Sklar, J. C. Fodor, E. Czogala, J. Drewniak, P. S. Mostert and A.

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Reciprocal Convex Costs for Ratio Matching: Axiomatic Characterization
AxiomsWe study ratio-induced mismatch cost functions of the form c(s,o)=JιS(s)/ιO(o) built from positive scale maps ιS:S→R>0 and ιO:O→R>0 and a penalty J:(0,∞)→[0,∞).

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes
FEBS Letters, EarlyView.Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics
