Oscillation for equations with positive and negative coefficients and distributed delay II: Applications

open access: yesElectronic Journal of Differential Equations, 2003
We apply the results of our previous paper "Oscillation of equations with positive and negative coefficients and distributed delay I: General results" to the study of oscillation properties of equations with several delays and positive and negative ...

Lost in clocks: non‐canonical circadian oscillation discovered in Drosophila cells

open access: yesMolecular Systems Biology, 2018
In most organisms, cell‐autonomous circadian clocks are driven by a transcription–translation negative feedback loop (TTFL). Per was the first identified clock gene in the fruit fly and is a core component of the circadian TTFL.

Natural Frequencies of Levodopa‐Induced Dyskinesia in Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Abnormal involuntary movements, known as dyskinesias, are common complications of levodopa treatment in patients with Parkinson's disease and can significantly impair quality of life. The underlying pathophysiology remains unclear, and current therapeutic options are limited.

The Madden Julian Oscillation: a literature review [PDF]

open access: yes, 2002
The literature survey reviews our present understanding of the Madden Julian Oscillation. This perturbation to the circulation of the tropical atmosphere involves anomalies in climate elements such as pressure, wind, outgoing long wave radiation, and ...

Asymptotic solutions of forced nonlinear second order differential equations and their extensions

open access: yesElectronic Journal of Differential Equations, 2007
Using a modified version of Schauder's fixed point theorem, measures of non-compactness and classical techniques, we provide new general results on the asymptotic behavior and the non-oscillation of second order scalar nonlinear differential equations on

Non-oscillation of linear differential equations with coefficients containing powers of natural logarithm

open access: yesOpen Mathematics
We study linear differential equations whose coefficients consist of products of powers of natural logarithm and general continuous functions. We derive conditions that guarantee the non-oscillation of all non-trivial solutions of the treated type of ...

Oscillation and non-oscillation criterion for Riemann–Weber type half-linear differential equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
By the combination of the modified half-linear Prüfer method and the Riccati technique, we study oscillatory properties of half-linear differential equations.

Gravity‐Dependent Modulation of Downbeat Nystagmus: Insights From Velocity‐Storage Dysfunction

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Downbeat nystagmus varies with head position, a phenomenon termed gravity‐dependent modulation. We aimed to clarify its mechanism using a velocity‐storage model. Methods In 10 patients with downbeat nystagmus due to cerebellar disorders, we recorded eye movements at different pitch‐ and roll‐axis head positions.
