Mini-TEPC Microdosimetric Study of Carbon Ion Therapeutic Beams at CNAO

EPJ Web of Conferences, 2017
Mono-energetic carbon ion scanning beams of 195.2 MeV/u at the Italian National Centre for Oncological Hadrontherapy (CNAO) have been used to study the microdosimetric features of an “active” carbon ion beam used in hadrontherapy.

Energy loss to conductors operated at lineal current densities ≤10  MA/cm: Semianalytic model, magnetohydrodynamic simulations, and experiment

Physical Review Special Topics. Accelerators and Beams, 2008
We have developed a semianalytic expression for the total energy loss to a vacuum transmission-line electrode operated at high lineal current densities. (We define the lineal current density j_{ℓ}≡B/μ_{0} to be the current per unit electrode width, where

Lineal energy-based evaluation of oxidative DNA damage induced by proton beams and X-rays [PDF]

International Journal of Radiation Biology, 2012
To determine the oxidative capabilities of proton beams compared to X-rays based on lineal energy (y).Microdosimetry was used to determine y-values of 155 MeV protons. Salmon testes deoxyribonucleic acid (ST-DNA) in solution and human tumor cells (MOLT-4) were irradiated with 200 kV X-rays (X) or 155 MeV protons at their plateau (P) and near their ...

Transmisión para una superred con modulación lineal de los anchos de las barreras

Nova Scientia, 2012
Usando el método de la matriz de transferencia y la ecuación de Ben Daniel y Duke para propagación de electrones con masa variable, calculamos la transmitancia para una superred lineal finita simétrica que tiene variación lineal del ancho de las barreras

Long-Duration Microdosimetry at the LNGS External Laboratory

Applied Sciences
Environmental radiation fields are characterized by very low dose rates and sparse energy-deposition events, conditions under which absorbed dose alone provides an incomplete description of irradiation at cellular and subcellular scales.

Linking Microdosimetric Measurements to Biological Effectiveness in Ion Beam Therapy: A Review of Theoretical Aspects of MKM and Other Models

Frontiers in Physics, 2021
Different qualities of radiation are known to cause different biological effects at the same absorbed dose. Enhancements of the biological effectiveness are a direct consequence of the energy deposition clustering at the scales of DNA molecule and cell ...

Range-shifter effects on the stray field in proton therapy measured with the variance–covariance method

Frontiers in Oncology, 2022
Measurements in the stray radiation field from a proton therapy pencil beam at energies 70 and 146 MeV were performed using microdosimetric tissue-equivalent proportional counters (TEPCs).

Partial Daylight Autonomy (DAp): A New Lighting Dynamic Metric to Optimize the Design of Windows for Seasonal Use Spaces

Applied Sciences, 2021
Nowadays, daylight dynamic metrics are the most useful indicators to quantify the use of natural light, with daylight autonomy (DA) being one of the most widespread among all of them.

Uncovering Inequities: The Role of Social Determinants of Health in Hospitalized Adolescents and Young Adults With Heavy Menstrual Bleeding

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Heavy menstrual bleeding (HMB) is a common condition among adolescents and young adults (AYAs) and is the leading cause of iron deficiency anemia (IDA) in this population. Growing evidence suggests that social determinants of health (SDOH) influence menstrual bleeding patterns, access to care, and treatment. However, no studies have
