Radion Inflation in Higher-Dimensional Gravity Theory

open access: yes, 2012
We study a radion model for inflation and density perturbation identifying the scalar field arising from the five-dimensional gravity on $M_4 x S^1$ with the inflaton.

Patterns of CT lung injury and toxicity after stereotactic radiotherapy delivered with helical tomotherapy in early stage medically inoperable NSCLC [PDF]

open access: yes, 2015
To evaluate toxicity and patterns of radiologic lung injury on CT images after hypofractionated image-guided stereotactic body radiotherapy (SBRT) delivered with helical tomotherapy (HT) in medically early stage inoperable non-small-cell lung cancer ...

Differential regulation of the Drosophila sleep homeostat by circadian and arousal inputs. [PDF]

open access: yes, 2019
One output arm of the sleep homeostat in Drosophila appears to be a group of neurons with projections to the dorsal fan-shaped body (dFB neurons) of the central complex in the brain.

Relativistic analysis of the dielectric Einstein box: Abraham, Minkowski and total energy-momentum tensors

open access: yes, 2011
We analyse the "Einstein box" thought experiment and the definition of the momentum of light inside matter. We stress the importance of the total energy-momentum tensor of the closed system (electromagnetic field plus material medium) and derive in ...

Complexity metrics for IMRT and VMAT plans: a review of current literature and applications.

open access: yesBritish Journal of Radiology, 2019
Modulated radiotherapy with multileaf collimators is widely used to improve target conformity and normal tissue sparing. This introduced an additional degree of complexity, studied by multiple teams through different properties.

Multi-task autoencoder based classification-regression model for patient-specific VMAT QA

open access: yesPhysics in Medicine and Biology, 2020
Patient-specific quality assurance (PSQA) of volumetric modulated arc therapy (VMAT) to assure accurate treatment delivery is resource-intensive and time-consuming. Recently, machine learning has been increasingly investigated in PSQA results prediction.

Automated contouring, treatment planning, and quality assurance for VMAT craniospinal irradiation (VMAT-CSI)

open access: yesFrontiers in Oncology
PurposeCreate a comprehensive automated solution for pediatric and adult VMAT-CSI including contouring, planning, and plan check to reduce planning time and improve plan quality.MethodsSeventy-seven previously treated CSI patients (age, 2-67 years) were used for creation of an auto-contouring model to segment 25 organs at risk (OARs).

Epigenetic mechanisms and therapeutic innovations in chronic pain‐associated neuropsychiatric co‐morbidities

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Chronic pain, marked by nociceptive sensitization and maladaptive neuroplasticity, affects 30% of the global population with escalating socioeconomic burdens. Epidemiological data show a 2‐3‐fold increase in neuropsychiatric co‐morbidities among individuals with chronic pain, where epigenetic dysregulation serves as a key mechanism linking ...
