Existence theorems for higher order boundary value problems [PDF]
In this paper the differential equation y ( n ) = f ( x , y ) {y^{(n)}} = f(x,y) and associated boundary conditions y (

ABSTRACT Background B‐acute lymphoblastic leukemia (B‐ALL) is the most common pediatric cancer, and while most children in high‐resource settings are cured, therapy carries risks for long‐term toxicities. Understanding parents’ concerns about these late effects is essential to guide anticipatory support and inform evolving therapeutic approaches ...

Existence of Heteroclinic Orbits in Fractional-Order and Integer-Order Coupled Lorenz Systems
Applying two Lyapunov functions and the concepts of α-/ω-limit sets, this paper reexamines fractional-order and integer-order coupled Lorenz systems and simultaneously proves the existence of twelve heteroclinic orbits, i.e., four ones to S0 and S5,6,7,8,

ABSTRACT Background The delipid extracorporeal lipoprotein filter from plasma (DELP) treatment can effectively reduce blood lipid, increase blood flow, and improve neurological deficits in patients with acute ischemic stroke (AIS). However, its effect on vision and retinal microcirculation in stroke patients has never been reported.

The existence and singularity structure of low regularity solutions of higher-order degenerate hyperbolic equations [PDF]
This paper is a continuation of our previous work [21], where we have established that, for the second-order degenerate hyperbolic equation (\p_t^2-t^m\Delta_x)u=f(t,x,u), locally bounded, piecewise smooth solutions u(t,x) exist when the initial data (u,\

Nontrivial solutions of systems of Hammerstein integral equations with first derivative dependence
By means of classical fixed point index, we prove new results on the existence, non-existence, localization and multiplicity of nontrivial solutions for systems of Hammerstein integral equations where the nonlinearities are allowed to depend on the first

Existence Results for First-Order Impulsive Differential Equations
With the help of a nonlinear Leray-Schauder type theorem the authors obtain some existence results for the impulsive initial value problem. They also study the periodic problem making use of upper and lower solutions. The results obtained complement those known in the literature.

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
