A Python package for fast GPU‐based proton pencil beam dose calculation

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Open‐source GPU‐based Monte Carlo (MC) proton dose calculation algorithms provide high speed and unparalleled accuracy but can be complex to integrate with new applications and remain slower than GPU‐based pencil beam (PB) methods, which sacrifice some physical accuracy for sub‐second plan calculation.

Log file‐based quality assurance method for respiratory gating system

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background As medical linear accelerator technology advances, enabling higher dose rate deliveries, hypofractionation regimens has increased. This necessitates respiratory gating systems that synchronize radiation delivery with tumor position, requiring simple rigorous quality assurance (QA) to ensure treatment accuracy and patient safety ...

Machine stability and dosimetry for ultra‐high dose rate FLASH radiotherapy human clinical protocol

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background The FLASH effect, induced by ultra‐high dose rate (UHDR) irradiations, offers the potential to spare normal tissue while effectively treating tumors. It is important to achieve precise and accurate dose delivery and to establish reliable detector systems, particularly for clinical trials needed to help the clinical transfer of FLASH‐

An MRI assessment of mechanisms underlying lesion growth and shrinkage in multiple sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
By applying the tensor model, we analysed lesion orientation and the directionality of lesion expansion/contraction in multiple sclerosis. Each lesion is summarized as an ellipsoid, and the tensor model is applied to calculate lesion anisotropy. From the top to the bottom white matter atlas, surface‐in gradient segmentation and venous atlas used in the

The Impact of In‐Hospital Disease Modifying Treatments on Mental and Physical Burden in Caregiver of Patients With MS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective People with multiple sclerosis (pwMS) may require a high level of daily assistance both for indoor and outdoor activities. Usually, relatives or friends provide daily support to MS patients who have lost personal autonomy. Several factors such as disability level and disease duration may affect the burden of care in caregivers of ...

Aspects of physics beyond the standard model

, 2021
Emprant els diferents problemes del Model Estàndar com a guia, en esta tesi presente noves teories que milloren la nostra descripció de la natura al nivell més fonamental. En la primera part, després de revisitar el Model Estàndar, enumere i descric les raons que tenim per a sospitar de l'existència d'una teoria més fonamental.

Symbolic regression for beyond the standard model physics

Physical Review D
We propose symbolic regression as a powerful tool for the numerical studies of proposed models of physics beyond the Standard Model. In this paper we demonstrate the efficacy of the method on a benchmark model, namely the constrained minimal supersymmetric Standard Model, which has a four-dimensional parameter space.

Home‐Based Tele‐tDCS in Amyotrophic Lateral Sclerosis: Feasibility, Safety, and Preliminary Efficacy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with limited treatment options. Transcranial direct current stimulation (tDCS) shows promise as a neuromodulatory intervention in various neurological disorders, but its application in ALS, particularly in a remote, home‐based format, remains underexplored.

Pharmacokinetics, Efficacy, and Safety of Upadacitinib in Pediatric Patients With Polyarticular‐Course Juvenile Idiopathic Arthritis: An Interim Analysis of an Open‐Label, Phase 1 Trial

Arthritis Care &Research, EarlyView.
Objective This work aimed to evaluate the pharmacokinetics, efficacy, and safety of upadacitinib, an oral selective JAK inhibitor, in pediatric patients with polyarticular‐course juvenile idiopathic arthritis (pcJIA). Methods In an open‐label, phase 1 study (SELECT‐YOUTH), enrolled patients, aged 2 to <18 years with pcJIA, received body weight–based ...
