Linearized oscillations for even-order neutral differential equations

Journal of Mathematical Analysis and Applications, 1991
For the n-th order neutral delay differential equation of the form \[ (d^ n/dt^ n)[y(t)-P(t)G(y(t-\tau))+Q(t)H(y(t-\sigma))]=0, \] where P, Q are positive functions, a comparison theorem is given under certain conditions. Conditions are given implying the oscillation of the bounded solutions of the nonlinear equation in case of the oscillation of all ...

Patient‐Level Barriers and Facilitators to Inpatient Physical Therapy in Adolescents and Young Adults With a Hematological Malignancy: A Qualitative Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Despite their increased risk for functional impairment resulting from cancer and its treatments, few adolescents and young adults (AYAs) with a hematological malignancy receive the recommended or therapeutic dose of exercise per week during inpatient hospitalizations.

Oscillatory criteria of noncanonical even-order differential equations with a superlinear neutral term

Boundary Value Problems
The oscillatory behavior of solutions of an even-order differential equation with a superlinear neutral term is considered using Riccati and generalized Riccati transformations, the integral averaging technique, and the theory of comparison.

Lyapunov-type inequalities for even order differential equations

Communications on Pure & Applied Analysis, 2012
In this paper, we establish several new Lyapunov-type inequalities for the $2n-$order differential equation $x^{(2n)}(t)+(-1)^{n-1}q(t)x(t)=0, $ which are sharper than all related existing ones.

A Comparative Study of Cerebral Oxygenation During Exercise in Hemodialysis and Peritoneal Dialysis Patients

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Some New Oscillation Criteria of Even-Order Quasi-Linear Delay Differential Equations with Neutral Term

Mathematics, 2021
The neutral delay differential equations have many applications in the natural sciences, technology, and population dynamics. In this paper, we establish several new oscillation criteria for a kind of even-order quasi-linear neutral delay differential ...

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
