Positive periodic solutions generated by impulses for the delay Nicholson's blowflies model
Electronic Journal of Qualitative Theory of Differential Equations, 2016 In this paper, by using Krasnoselskii's fixed point theorem, we study the existence and multiplicity of positive periodic solutions for the delay Nicholson's blowflies model with impulsive effects.

Prediction Model for Etiologic Differentiation of Isolated Vestibular Syndrome in Emergency Settings
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective This study aimed to develop and validate a predictive model for differentiating central from peripheral etiologies in patients with isolated vestibular syndrome (VS). Methods In this multicenter retrospective cohort study, 506 patients with isolated VS from five hospitals were divided into derivation (n = 301) and validation (n = 205)

On gradual-impulse control of continuous-time Markov decision processes with multiplicative cost
, 2018 In this paper, we consider the gradual-impulse control problem of continuous-time Markov decision processes, where the system performance is measured by the expectation of the exponential utility of the total cost. We prove, under very general conditions

Decreased Serum 5‐HT: Clinical Correlates and Regulatory Role in NMJ of MG
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Although 5‐Hydroxytryptamine (5‐HT) indirectly stimulates muscle contraction and participates in regulating Acetylcholine receptor (AChR) cluster homeostasis in cellular, animal, and clinical studies, evidence regarding its potential to modulate muscle contraction in myasthenia gravis (MG) remains limited.

Real‐World Investigation of Satralizumab in Patients With Neuromyelitis Optica Spectrum Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Satralizumab, a monoclonal antibody targeting the interleukin‐6 receptor, has demonstrated efficacy in clinical trials for neuromyelitis optica spectrum disorder (NMOSD). However, its real‐world effectiveness and safety compared to conventional immunosuppressive therapies remain uncertain.

Economic determinants of the nominal treasury yield curve [PDF]
We study the effect of different types of macroeconomic impulses on the nominal yield curve. We employ two distinct approaches to identifying economic shocks in VARs. Our first approach uses a structural VAR due to Galí (1992).

Does trait impulsivity differentiate impulsive from non-impulsive suicide attempts?
Journal of Psychiatric ResearchBACKGROUND: Suicide poses a major public health concern, with impulsive suicide and suicide attempts representing a particularly difficult subset of cases for effective suicide prevention. The relationship between impulsive suicidal behavior (ISB) and impulsivity as a trait, which can be assessed by specific questionnaires, is still unclear. This study,
