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.

Vectoring Control of Bilateral Parallel Offset Jet: Flow Characteristics and Control Mechanism

Aerospace
We proposed a bilateral parallel offset jet model that enables jet vectoring control without the need for an active high-pressure secondary flow. Flow characteristics, including deflection force, wall pressure distribution, and flow structures, were ...

Treatment Continuation and Long‐Term Outcomes of Perampanel in Primary Orthostatic Tremor; A Cohort Study

Movement Disorders Clinical Practice, EarlyView.
Background Primary orthostatic tremor (POT) is a rare hyperkinetic movement disorder with limited and largely ineffective treatment options. Perampanel has been suggested as a therapy, but has so far only been investigated in small studies with short duration.

Orthostatic Myoclonus—Clinical and Electrophysiological Features in a Large Retrospective Cohort

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Orthostatic myoclonus is characterized by irregular, lower limb myoclonic bursts during stance and is a major cause of postural instability and falls. However, studies are limited, and little is known about its pathophysiology. Objectives We sought to define the clinical and electrophysiological features of orthostatic myoclonus in ...

Numerical study of nonlinearity of unsteady aerodynamics for NLR7301 profile

, 2005
Details of unsteady aerodynamics for a two dimensional NLR7301 airfoil with flap were numerically investigated by a Navier-Stokes code in the transonic regime. Unsteady aerodynamic coefficients such as lift and pitching moment show nonlinear aspects in a

The Combined Effects of Variable Viscosity and Thermal Conductivity of An Unsteady Casson Fluid Flow Along a Vertical Porous Channel With Convective Cooling Walls, Using the Bivariate Spectral Local Linearization Method

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This study examines the combined impact of different thermal conductivity and viscosity on unsteady non‐Newtonian Casson fluid flow of incompressible, electrical conductivity in a porous vertical channel with convective cooling walls, uniform magnetic field, and constant pressure gradient.

A new meshless RBF-based method for unsteady fluid flow analysis [PDF]

, 2006
In this paper, the indirect radial basis function network (IRBFN) method is further developed to solve some unsteady fluid flow problems including the un-steady Navier-Stokes equations (UNSE) and moving interface ...
