Implementation of a novel pencil beam scanning Bragg peak FLASH technique to a commercial treatment planning system

open access: yesMedical Physics, EarlyView.
Abstract Background Ultra‐high dose rate, or FLASH, radiotherapy has shown promise in preclinical experiments of sparing healthy tissue without compromising tumor control. This “FLASH effect” can compound with dosimetric sparing of the proton Bragg peak (BP) using a method called Single Energy Pristine Bragg Peak (SEPBP) FLASH.

Experimental validation of Geant4 nuclear interaction models in dose calculations of therapeutic carbon ion beams

open access: yesMedical Physics, EarlyView.
Abstract Background The choice of nuclear interaction models in Monte Carlo simulations affects the dose calculation accuracy for light ion beam therapy. Purpose This study aimed to evaluate the dose calculation accuracy and simulation time of three GATE‐RTiON/Geant4 physics lists for therapeutic carbon ion beams, assessing their suitability for ...

Penta‐ and Hexacoordinated Copper(II) Complexes with Azido and 4‐amino‐3,5‐di‐2‐pyridyl‐4H‐1,2,4‐triazole Ligands with Field‐Induced Slow Magnetic Relaxation

open access: yesChemistryOpen, EarlyView.
A field‐induced slow magnetic relaxation was observed in an ionic pentacoordinated Cu(II) complex with 4‐amino‐3,5‐di‐2‐pyridyl‐4H‐1,2,4‐triazole and azido ligands. The analysis of the relaxation behaviour supports the origin of the slow magnetic relaxation in intramolecular low‐energy vibration modes participating in the one‐phonon direct and two ...

Quantifying Molecular Properties of Hexagonal Water Clusters

open access: yesChemistryOpen, EarlyView.
Standard quantum chemical calculations on large hexagonal water clusters allow us to analyze the fundamental properties of ice‐Ih. Computed geometrical structure, energies, and vibrational spectra are astonishingly close to experimental data without the introduction of any external empirical parameters.
