The Role of Calcitonin Gene‐Related Peptide in High‐Altitude Headache: A Prospective Field Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective High‐altitude headache (HAH) is a common neurological condition associated with rapid ascent to high altitude. The pathophysiological mechanisms underlying HAH remain incompletely understood. Calcitonin gene‐related peptide (CGRP), a neuropeptide implicated in migraine pathophysiology, may play a key role in the pathophysiology of ...

Choroid Plexus Enlargement and USPIO‐Based Inflammatory Feature in Cerebral Small Vessel Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective The choroid plexus (CP) is a key component of the blood–cerebrospinal fluid barrier (BCSFB), but its mechanism of action in cerebral small vessel disease (CSVD) remains unclear. This study investigated CP volume (CPV) alterations and their association with conventional imaging markers in CSVD and explored the underlying role of ...

Local spectral analysis of class wF(p, r, q) operators via Dunford property theory
Recent Advances in Natural SciencesThis paper investigates the local spectral properties of class (w mathcal{F}(p,r,q)\) operators. By establishing connections with a related operator-equation framework, we show that these operators satisfy important spectral properties, including the ...

Two Types of Solutions to a Class of (p,q)-Laplacian Systems with Critical Sobolev Exponents in RN
Advances in Mathematical Physics, 2018 We focus on the following elliptic system with critical Sobolev exponents: -div∇up-2∇u+m(x)up-2u=λup⁎-2u+(1/η)Gu(u,v), x∈RN; -div∇vq-2∇v+n(x)vq-2v=μvq⁎-2v+(1/η)Gv(u,v), x∈RN; u(x)>0,v(x)>0, x∈RN, where μ,λ>0 ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Cognitive impairment is a common non‐motor symptom in Multiple Sclerosis (MS), negatively affecting autonomy and Quality of Life (QoL). Innovative rehabilitation strategies, such as semi‐immersive virtual reality (VR) and computerized cognitive training (CCT), may offer advantages over traditional cognitive rehabilitation (TCR ...

Inflation, Taxation, and Corporate Investment: A q-Theory Approach [PDF]
This paper presents an analysis of the effects of tax policy on capital accumulation and valuation based on James Tobin's q theory of investment. As Tobin has explained, aggregate investment can be expected to depend in a stable way on q, the ratio of ...

Coloring problems in graph theory: k-packings and (p,q)-colorings [PDF]
A graph coloring is a map $\varphi$ from the vertices (or edges) of a graph $G$ to a set of colors. In Chapters 1 and 2, we provide preliminary information about graph theory and graph colorings and offer motivation behind the work.

New W_{q,p}(sl(2)) algebras from the elliptic algebra A_{q,p}(sl(2)_c)
, 1998 International audienceWe construct operators t(z) in the elliptic algebra introduced by Foda et al. A_{q,p}sl(2)_c). They close an exchange algebra when p^m=q^{c+2} for m integer.
