On the boundedness of solution of the second order ordinary differential equation with damping term and involution

Қарағанды университетінің хабаршысы. Математика сериясы, 2021
In the present paper the initial value problem for the second order ordinary differential equation with damping term and involution is investigated. We obtain equivalent initial value problem for the fourth order ordinary differential equations to the ...

Comparison of kinship‐identification methods for robust stock assessment using close‐kin mark–recapture data for Pacific bluefin tuna

Population Ecology, Volume 67, Issue 2, Page 140-152, April 2025.
In this study, we compared three methods for kinship identification using different algorithms in samples of wild Pacific bluefin tuna and generated genotyping data. The three methods resulted in different numbers of inferred kinship pairs for both generated and actual data. Particularly for the half‐sibling pairs, considerable number of false‐positive

Discrete Orthogonal Polynomials with Hypergeometric Weights and Painlev\'e VI

, 2018
We investigate the recurrence coefficients of discrete orthogonal polynomials on the non-negative integers with hypergeometric weights and show that they satisfy a system of non-linear difference equations and a non-linear second order differential ...

Population and species neighbor identity impact trait–trait relationships and plant performance

Population Ecology, EarlyView.
We evaluated how populations and species identity influence plant performance and trait outcomes in mixtures, and assessed trait variation among populations of two forb species native to the western United States (Dieteria canescens and Heterotheca villosa) following three interaction treatments (single‐population monoculture, two‐population mixture ...

Solving Linear Differential Equations [PDF]

Pure and Applied Mathematics Quarterly, 2010
The theme of this paper is to 'solve' an absolutely irreducible differential module explicitly in terms of modules of lower dimension and finite extensions of the differential field K. Representations of semi-simple Lie algebras and differential Galo is theory are the main tools. The results extend the classical work of G. Fano.

Human colon organoid differentiation from induced pluripotent stem cells using an improved method

FEBS Letters, Volume 599, Issue 6, Page 912-924, March 2025.
We compared established protocols to differentiate induced pluripotent stem cells into colon organoids and found that activation of bone morphogenetic protein 2 signaling induced gene expression of colon‐specific markers. Adenovirus‐mediated transduction of the transcription factors HOXD13 or SATB2 further enhanced colonic gene expression, suggesting ...

Insights into the renal pathophysiology in Hermansky‐Pudlak syndrome‐1 from urinary extracellular vesicle proteomics and a new mouse model

FEBS Letters, Volume 599, Issue 7, Page 1055-1074, April 2025.
Hermansky‐Pudlak syndrome type 1 (HPS‐1) is a rare, autosomal recessive disorder with poorly understood renal involvement. Urinary extracellular vesicle (uEV) proteomics and a novel Hps1 mouse model reveal mitochondrial abnormalities and lipid accumulation in HPS‐1 kidney proximal tubule cells. Serum ApoA1 correlates with kidney function in our patient

Oscillation of Half-Linear Differential Equations with Delay

Abstract and Applied Analysis, 2013
We study the half-linear delay differential equation , , We establish a new a priori bound for the nonoscillatory solution of this equation and utilize this bound to derive new oscillation criteria for this equation in terms of oscillation criteria for ...

Numerical integration of the boundary value problems for the second order nonlinear ordinary differential equations of an arbitrary structure using an iterative procedure

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2016
An iterative procedure for numerical integration of boundary-value problems for nonlinear ordinary differential equations of the second order of arbitrary structure is suggested.
