Bright OB stars in the Galaxy.II. Wind variability in O supergiants as traced by H-alpha

, 2005
We investigate the line-profile variability (lpv) of H-alpha for a large sample of O-type supergiants. We used the Temporal Variance Spectrum (TVS) analysis, developed by Fullerton et al 1996 and modified by us to take into account the effects of wind ...

Tissue oxygenation dynamics during transition from seizure to spreading depolarization in rat brain

Epilepsia, EarlyView.
Abstract Objective Spreading depolarization (SD) is a phenomenon underlying various neurological conditions, including epilepsy. Researchers have suspected that local tissue oxygenation breakdown induces spontaneous SD. In this study, we investigated the relationship between spontaneous epileptic seizures and SD, with a focus on the role of local ...

Voice and Speech in Atypical Parkinsonian Disorders

Movement Disorders Clinical Practice, EarlyView.
Background Motor speech disorders are early, common, and functionally limiting features of atypical parkinsonian disorders (APDs) such as progressive supranuclear palsy (PSP), corticobasal syndrome (CBS), and multiple system atrophy (MSA). These impairments are underrecognized and undertreated in neurology clinics.

Lecanicillium aphanocladii: a biocontrol agent against insect pests and phytopathogens

Pest Management Science, EarlyView.
Recent research findings on the biocontrol potential of Lecanicillium aphanocladii fungus against insect‐pests and plant diseases were highlighted. This review indicates that several L. aphanocladii strains show great potential to be developed as multipurpose biocontrol agents active against several insect‐pests, plant diseases and plant parasitic ...

Periodic Scenario Trees: A Novel Framework for Robust Periodic Invariance and Stabilization of Constrained Uncertain Linear Systems

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This work proposes a new framework for stabilizing uncertain linear systems and for determining robust periodic invariant sets and their associated control laws for constrained uncertain linear systems. Necessary and sufficient conditions for stabilizability by periodic controllers are stated and proven using finite step Lyapunov functions for
