On the Exact Form of V.A. Dykhta’s Feedback Minimum Principle in Nonlinear Control Problems

Известия Иркутского государственного университета: Серия "Математика"
This paper investigates a nonlinear optimal control problem for an ordinary differential equation (in the sense of Bochner) on a Banach space. The problem is posed in the class of conventional controls – measurable, essentially bounded functions of time –

RNA Sequencing Resolves Cryptic Pathogenic Variants in Mitochondrial Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Mitochondrial diseases are the most common inherited metabolic disorders, characterized by pronounced clinical and genetic heterogeneity that complicates molecular diagnosis. Although DNA‐based sequencing approaches have become standard in genetic testing, up to half of patients remain without a definitive diagnosis.

High‐Resolution MRI Revealed Different Etiology‐Specific Associations With Cerebral Infarction in Adult Moyamoya Vasculopathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective High‐resolution MRI enables detailed assessment of intracranial vessel wall pathology in moyamoya vasculopathy. We aimed to classify adult moyamoya vasculopathy etiologies using high‐resolution MRI and to examine subtype‐specific associations between high‐resolution MRI features and ischemic infarction.

ALGORITHMIZATION OF CALCULATIONS OF THE KOLMOGOROV–NIKOL’SKII CONSTANTS FOR VALUES OF APPROXIMATIONS OF CONJUGATED DIFFERENTIABLE FUNCTIONS BY GENERALIZED POISSON INTEGRALS

Міжнародний науково-технічний журнал "Проблеми керування та інформатики"
In applied mathematics in solving a number of problems, it is advisable to use the methods and approaches of approximation theory. One of the most important types of problems, of both the theory of approximation of functions and applied mathematics, is ...

Numerical study of manifold computations [PDF]

, 2003
In this paper we study the numerical accuracy of computing one-dimensional manifolds of (non-hyperbolic) equilibria in a planar vector field for which the manifolds are known explicitly.

Advancing Age Modulates Associations Between Cognitive Impairment and Brain Volumes in Early MS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Cognitive impairment is common in multiple sclerosis (MS), but manifestations following the first demyelinating event are relatively unexplored. We investigated cross‐sectional associations between magnetic resonance imaging (MRI)–derived brain volumes and the presence of cognitive impairment outcomes five years after the first ...

Predictive Ability of Plasma p‐tau217 for β‐Amyloid Status: A Prospective Multicenter Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Plasma tau phosphorylated at threonine 217 (p‐tau217) measured with fully automated platforms has shown high accuracy for Alzheimer's disease (AD) diagnosis, but real‐world multicenter data remain limited. We aimed to validate the diagnostic performance of p‐tau217 for identifying AD pathology in a real‐world multicenter cohort ...
