Comparison of antiviral effect for mild-to-moderate COVID-19 cases between lopinavir/ritonavir versus hydroxychloroquine: A nationwide propensity score-matched cohort study

International Journal of Infectious Diseases, 2021
Objectives: We aimed to compare the antiviral effect of hydroxychloroquine (HCQ) and lopinavir/ritonavir (LPV/r) in patients with COVID-19. Methods: Nationwide retrospective case-control study was conducted to compare the effect of HCQ and LPV/r on viral

Population pharmacokinetic/pharmacodynamic modelling to evaluate favipiravir in combination with lopinavir–ritonavir in patients with COVID‐19

British Journal of Clinical Pharmacology, EarlyView.
Aims The repurposed use of favipiravir in COVID‐19 has been reported to have limited clinical efficacy, yet it has been widely used in some countries. Favipiravir causes mutagenesis in RNA viruses, and it is currently unknown whether it may have a measurable effect on the virus in humans.

Surgery of spline-type and molecular frames [PDF]

, 2009
We prove a result about producing new frames for general spline-type spaces by piecing together portions of known frames. Using spline-type spaces as models for the range of certain integral transforms, we obtain results for time-frequency decompositions

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 ...

Moment Matching Based Model Reduction for LPV State-Space Models

, 2015
We present a novel algorithm for reducing the state dimension, i.e. order, of linear parameter varying (LPV) discrete-time state-space (SS) models with affine dependence on the scheduling variable.

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.

LPV Control for the Full Region Operation of a Wind Turbine Integrated with Synchronous Generator

The Scientific World Journal, 2015
Wind turbine conversion systems require feedback control to achieve reliable wind turbine operation and stable current supply. A robust linear parameter varying (LPV) controller is proposed to reduce the structural loads and improve the power extraction ...

Sliding Mode Control in Aerospace Applications: A Survey

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Linear Parameter-Varying Control of a Ducted Fan Engine [PDF]

, 1995
Parameter-dependent control techniques are applied to a vectored thrust, ducted fan engine. The synthesis technique is based on the solution of Linear Matrix Inequalities and produces a controller which achieves specified performance against the worst ...

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 ...
