Cortical Excitability Before and After Long‐Term Perampanel Treatment for Epilepsy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Antiseizure medications (ASMs), which may influence cortical excitability, are the mainstay of epilepsy treatment. Transcranial magnetic stimulation (TMS) helps evaluate cortical excitability. We assessed changes in TMS responses using serial TMS measurements in people treated with an adjunctive noncompetitive AMPA‐receptor ...

The ozone radiative forcing of nitrogen oxide emissions from aviation can be estimated using a probabilistic approach

open access: yesCommunications Earth & Environment
Reliable prediction of aviation’s environmental impact, including the effect of nitrogen oxides on ozone, is vital for effective mitigation against its contribution to global warming.

Aircraft noise control [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1995
The purpose of this paper is to describe the research program in aircraft acoustics being conducted by the NASA–Langley Research Center. The program includes research to understand, predict, and reduce the sources of aircraft noise; to quantify the transmission of noise through the atmosphere and/or aircraft structures; and to define the effects of ...

EEG Spectral Exponents and Visual Chirp Responses Mirror Anti‐Seizure Medication Load in Refractory Focal Epilepsy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Quantitative markers of cortical excitability may help identify responders to anti‐seizure medications (ASMs). We studied the relationship between ASM load and two electroencephalography (EEG) markers of cortical excitability in people with refractory epilepsy. Methods We included individuals with refractory focal epilepsy undergoing

Analysis of the Longitudinal Behavior of Serum Levels of Soluble Flt1 and Placental Growth Factor in Pregnant Patients With Systemic Lupus Erythematosus

open access: yesArthritis Care &Research, EarlyView.
Objective This study analyzed longitudinal trajectories of soluble Flt1 (sFlt1) levels, placenta growth factor (PlGF) levels, and sFlt1:PlGF ratios in a cohort of pregnant patients with systemic lupus erythematosus (SLE). Methods Blood samples were collected (14–18, 24–26, 30–32, 34–36, and 38–40 weeks), stored at −80°C, and evaluated for serum levels ...

Nonlinear Noise Mechanisms in Active Devices: Additive Amplitude Noise and Phase Noise [PDF]

open access: yesarXiv
In this report, we lay the foundation for amplitude noise and phase noise analysis in nonlinear devices. We build a theoretical framework that helps us to analyze extremely difficult problems which include both nonlinearity and noise of semiconductors.
