Existence of positive almost periodic solutions for delay Lotka-Volterra cooperative systems
In this article, we study a Lotka-Volterra cooperative system of equations with time-varying delays and distributed delays. By using Mawhin's continuation theorem of coincidence degree theory, we obtain sufficient conditions for the existence of ...

Epigenetic reprogramming in hematopoietic stem and progenitor cells (HSPCs) and downstream myeloid cells, mediated by H3.3 downregulation and endogenous retroelement (ERE) overexpression, contributes to the progression of multiple sclerosis (MS). ABSTRACT Background Skewed myelopoiesis in the bone marrow has been identified as a key driver of multiple ...

Existence of periodic solutions for second order delay differential equations with impulses
Using the coincidence degree theory by Mawhin, we prove the existence of periodic solutions for the second-order delay differential equations with impulses $displaylines{ x''(t)+f(t,x'(t))+g(x(t-au(t))=p(t),quad tgeq0,; teq t_k,cr Delta x(t_k)=I_k(x(

Dirac–Bergmann analysis and degrees of freedom of coincident f(Q)-gravity
AbstractWe investigate the propagating degrees of freedom off(Q)-gravity in a 4-dimensional space-time under the imposition of the coincident gauge by performing the Dirac–Bergmann analysis. In this work, we start with a top-down reconstruction of the metric-affine gauge theory of gravity based only on the concept of a vector bundle.

Objective Ultrasound (US) has been proposed as a potential tool for assessing skin fibrosis in systemic sclerosis (SSc). However, a large‐scale comparison of US‐based assessment with histologic markers of skin fibrosis has not been reported. We evaluated US‐based skin assessments for their face validity (differentiation between involved SSc and healthy

Periodic solutions for a food chain system with Monod-Haldane functional response on time scales
In this article, we study a three species food chain model on time scales, with Monod-Haldane functional response and time delay. With the help of coincidence degree theory, we establish the existence of periodic solutions.

Correlation between clinical diagnostics and necropsical findings
Background: the indices of discrepancy and coincidence of the causes of death between the clinical and morphological diagnosis constitute, indirectly, an indicator of the quality of medical care. Objective: to determine the relationship between clinical
