On Invariant Vectors in the Presence of Electric and Magnetic Fields

open access: yesAtoms, 2023
In this non-exhaustive review, we discuss the importance of invariant vectors in atomic physics, such as the Laplace–Runge–Lenz vector, the Redmond vector in the presence of an electric field, the Landau–Avron–Sivardièrevector when the system is subject ...

Multi-Configuration Calculation of Ionization Potential Depression

open access: yesPlasma, 2022
The modelling of ionization potential depression in warm and hot dense plasmas constitutes a real theoretical challenge due to ionic coupling and electron degeneracy effects.

Organoids in domestic animals: with which stem cells?

open access: yesVeterinary Research, 2021
Organoids are three-dimensional structures that are derived from the self-organization of stem cells as they differentiate in vitro. The plasticity of stem cells is one of the major criteria for generating organoids most similar to the tissue structures ...

Adaptive Algorithm for the Generation of Superconfigurations in Hot-Plasma Opacity Calculations

open access: yesPlasma, 2022
In hot plasmas, such as the ones encountered in astrophysics or laser-fusion studies, the number of ionic excited states may become huge, and the relevant electron configurations cannot always be handled individually.

Application value of contrast‐enhanced ultrasound in preoperative localization of microwave ablation for primary hyperparathyroidism

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Background Ultrasonography (US) and 99mTechnetium‐sestamibi scintigraphy (99mTc‐MIBI) are currently first‐line imaging modalities to localize parathyroid adenomas with sensitivities of 80% and 84%, respectively. Therefore, finding other modalities to further improve the diagnostic accuracy for preoperative localization is critically needed ...

Super Transition Arrays: A Tool for Studying Spectral Properties of Hot Plasmas

open access: yesPlasma, 2021
For the theoretical study of X and extreme-UV spectra of ions in plasmas, quantum mechanics brings more detailed results than statistical physics. However, it is impossible to handle individually the billions of levels that must be taken into account in ...

A transient inflammatory response contributes to oxaliplatin neurotoxicity in mice

open access: yesAnnals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1985-1998, December 2022., 2022
Abstract Objectives Peripheral neuropathy is a relevant dose‐limiting adverse event that can affect up to 90% of oncologic patients with colorectal cancer receiving oxaliplatin treatment. The severity of neurotoxicity often leads to dose reduction or even premature cessation of chemotherapy.

Synthetic exposure with a CMOS camera for multiple exposure speckle imaging of blood flow

open access: yesScientific Reports, 2022
Speckle contrast imaging is an established technique to obtain relative blood flow maps over wide fields of view. A major improvement of the method relies on the acquisition of raw speckle images at different exposure times but requires simultaneous ...

Biorhetorics: An introduction to applied rhetoric

open access: yesSign Systems Studies, 2002
This paper is an introduction to the new field of biorhetorics. Biorhetorics is an applied form of rhetoric that evolved from the study of classical rhetoric, particularly Aristotelian.

From biorhetorics to zoorhetorics

open access: yesSign Systems Studies, 2009
The present article aims to introduce the field of “Zoorhetorics”, as a particular case of Biorhetorics, earlier introduced by the author in the academic world.
