Accounting for TLD response to CBCT protocols in external beam radiotherapy dose monitoring

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose LiF thermoluminescent dosimeters (TLDs) are commonly used in radiation therapy to verify the delivered dose. Examples include dose verification for complicated treatment setups or cardiovascular implantable electronic devices (CIEDs). TLDs may be present for both the pre‐treatment imaging kilovoltage (kV) beam and the megavoltage (MV ...

Mean Square Exponential Stability of Stochastic Cohen-Grossberg Neural Networks with Unbounded Distributed Delays

open access: yesDiscrete Dynamics in Nature and Society, 2010
This paper addresses the issue of mean square exponential stability of stochastic Cohen-Grossberg neural networks (SCGNN), whose state variables are described by stochastic nonlinear integrodifferential equations.

Exponential stability for linear evolutionary equations [PDF]

open access: yesAsymptotic Analysis, 2013
We give an approach to exponential stability within the framework of evolutionary equations due to Picard [Math. Methods Appl. Sci. 32(14) (2009), 1768–1803]. We derive sufficient conditions for exponential stability in terms of the material law operator which is defined via an analytic and bounded operator-valued function and give an estimate for the

Sharp conditions for exponential and non-exponential uniform stabilization of the time-dependent damped wave equation [PDF]

open access: yesarXiv, 2023
It is classical that uniform stabilization of solutions to the autonomous damped wave equation is equivalent to every geodesic meeting the positive set of the damping, which is called the geometric control condition. In this paper, it is shown that for time-dependent damping, a generalization of the geometric control condition is equivalent to uniform ...

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 Flt‐1 and Placental Growth Factor in pregnant women with Systemic Lupus Erythematosus

open access: yesArthritis Care &Research, Accepted Article.
Objective This study analyzed longitudinal trajectories of soluble fms‐like tyrosine kinase‐1 (sFlt‐1) and placental growth factor (PlGF) and sFlt‐1/PlGF ratio 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 ...
