Existence of Solutions for Weighted p(r)-Laplacian Impulsive Integro-Differential System Periodic-Like Boundary Value Problems

Journal of Inequalities and Applications, 2010
This paper investigates the existence of solutions for weighted p(r)-Laplacian impulsive integro-differential system periodic-like boundary value problems via Leray-Schauder's degree. The sufficient conditions for the existence of solutions are given.

Adaptive and non-adaptive minimax rates for weighted Laplacian-eigenmap based nonparametric regression

, 2023
We show both adaptive and non-adaptive minimax rates of convergence for a family of weighted Laplacian-Eigenmap based nonparametric regression methods, when the true regression function belongs to a Sobolev space and the sampling density is bounded from ...

Population Pharmacokinetics and Detection Times of Betamethasone After Intravenous, Intramuscular, and Intranasal Jet Administration of Betamethasone Sodium Phosphate in Horses

Drug Testing and Analysis, EarlyView.
Betamethasone concentrations in 20 horses from Japan and Germany following IV, IM, and INJ administration of betamethasone phosphate were analyzed using population pharmacokinetic modeling. For IV administration of 0.04 mg/kg q24 h, IPC and IUC were 0.012 and 0.31 ng/mL, respectively; the IUC approximated the IFHA urine ISL (0.20 ng/mL).

Estimate Laplacian Spectral Properties of Large-Scale Networks by Random Walks and Graph Transformation

Mathematics
For network graphs, numerous graph features are intimately linked to eigenvalues of the Laplacian matrix, such as connectivity and diameter. Thus, it is very important to solve eigenvalues of the Laplacian matrix for graphs.

Brain‐wide magnetic resonance imaging analysis of neurobehavioral comorbidities in temporal lobe epilepsy

Epilepsia, EarlyView.
Abstract Objective In temporal lobe epilepsy (TLE), patients often present with neurobehavioral comorbidities encompassing affective and cognitive difficulties. Whereas the latter have been related to atypical connectivity of mesiotemporal and frontotemporal circuits, the brain basis of affective symptoms remains incompletely understood.

Nonnegative solutions of nonlinear fractional Laplacian equations [PDF]

, 2020
The study of reaction-diffusion equations involving nonlocal diffusion operators has recently flourished. The fractional Laplacian is an example of a nonlocal diffusion operator which allows long-range interactions in space, and it is therefore important

Association Between Deep Gray Matter Iron Deposition Dysregulation and Cognitive Performance in Type 2 Diabetes Mellitus Patients: A Quantitative Susceptibility Mapping Study

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Type 2 diabetes (T2DM) heightens cognitive impairment risk, yet the mechanisms remain unclear. Hyperglycemia‐induced iron dysregulation in deep gray matter (DGM) nuclei may be a crucial mechanism. Purpose To investigate DGM iron deposition in T2DM using Quantitative Susceptibility Mapping (QSM) and determine its association with ...
