Қарағанды университетінің хабаршысы. Математика сериясы, 2020 The article is devoted to the study of the asymptotic behavior of solving an integral boundary value problem for a third - order linear differential equation with a small parameter for two higher derivatives, provided that the roots of the "additional ...

Expert Systems, Volume 43, Issue 3, March 2026.ABSTRACT Zero‐day exploits remain challenging to detect because they often appear in unknown distributions of signatures and rules. The article entails a systematic review and cross‐sectional synthesis of four fundamental model families for identifying zero‐day intrusions, namely, convolutional neural networks (CNN), deep neural networks (DNN ...

International Journal of Differential Equations, 2017 In this work, approximations to the solutions of singularly perturbed second-order linear delay differential equations are studied. We firstly use two-term Taylor series expansion for the delayed convection term and obtain a singularly perturbed ordinary

VIEW, Volume 7, Issue 1, February 2026.Inhibiting the SUMOylation modification of TRPM4 can prevent the vascular endothelial damage caused by ATO. Inhibition of TRPM4 SUMOylation, either pharmacologically by GA or genetically by the K618R mutation, protects against ATO‐induced vascular endothelial damage.

Singularly perturbed vector fields
Journal of Physics: Conference Series, 2006 A geometrically invariant concept of singularly perturbed systems of ordinary differential equations (singularly perturbed vector fields) is proposed in this paper. Singularly perturbed vector fields can be represented locally as singularly perturbed systems (for corresponding coordinate system choice.

International Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.ABSTRACT The multiresolution finite wavelet domain method has been meticulously studied in numerous wave propagation simulations, showing excellent convergence properties and very fast computing times. The multiresolution procedure always starts with the coarse solution, and then finer solutions can be superimposed on the coarse solution until ...

Singularly perturbed stochastic systems [PDF]
Ukrainian Mathematical Journal, 1997 Summary: Problems of the singular perturbation of reducible invertible operators are classified and their applications to the analysis of stochastic Markov systems represented by random evolutions are considered. The phase merging, averaging, and diffusion approximation schemes are discussed for dynamical systems with rapid Markov switchings.

CNS Neuroscience &Therapeutics, Volume 32, Issue 1, January 2026.Our multiomics analysis across three PD cohorts revealed distinct fecal microbiome and plasma metabolome alterations in patients with motor complications (PD‐MC). We identified specific microbial and metabolic biomarkers and uncovered significant correlations between them, providing new insights into PD‐MC pathophysiology. ABSTRACT Background Parkinson'

Roars, Rumbles, and Resonance: A Systematic Review and Meta‐Analysis of Crocodylian Acoustic Signals
Ecology and Evolution, Volume 16, Issue 1, January 2026.Crocodylians are highly vocal reptiles, possessing a complex acoustic signalling system including vocal and non‐vocal signals used for courtship, mating, mediating conflict, and providing maternal care. Despite this, research on crocodylian acoustic signalling remains infrequent, with methodologies and terminology varying widely across studies.
