Quantifying uncertainty in calibration and clinical application of EBT-4 Gafchromic film dosimetry. [PDF]
Abstract Background GAFchromic films (GAFs) are essential tools in radiotherapy dosimetry, but uncertainties in calibration methods limit their accuracy and hinder consistency across clinical practice. Purpose This study aimed to perform a comparative analysis of different calibration functions for GAFchromic EBT4 films in single‐ and double‐channel ...

Variational approach to multimode nonlinear optical fibers. [PDF]
Abstract We analyze the spatiotemporal solitary waves of a graded‐index multimode optical fiber with a parabolic transverse index profile. Using the nonpolynomial Schrödinger equation approach, we derive an effective one‐dimensional Lagrangian associated with the Laguerre–Gauss modes with a generic radial mode number p and azimuthal index m.

Biographie des Astronomen und Mathematikers Galileo Galilei (1564-1642). Der Inquisitionsprozess 1633 wird ausführlich geschildert, wenn ihm auch - wie Moritz Cantor bedauernd erklärt - ein Einblick in die Prozessakten, die erst 1984 freigegeben wurden, vom Vatikan nicht gewährt wurde.

Learning to communicate. The experience of an Italian emergency department
Dear Editor, In his essay "Considerations on Tasso," published in 1793, Galileo Galilei described Tasso as a man poor in concepts and lacking in knowledge, who resorted to literary subterfuges and "abstruse" literary techniques, thereby emphasizing the ...

A fresh view on string orbifolds
In quantum field theory, an orbifold is a way to obtain a new theory from an old one by gauging a finite global symmetry. This definition of orbifold does not make sense for quantum gravity theories, that admit (conjecturally) no global symmetries.

Binary Black Hole Spins: Model Selection with GWTC-3
The origin of the spins of stellar-mass black holes is still controversial, and angular momentum transport inside massive stars is one of the main sources of uncertainty. Here, we apply hierarchical Bayesian inference to derive constraints on spin models

The nature of young star clusters in the Magellanic Clouds is debated. Here, the authors show an alternative approach that exploits data to exclude the presence of age differences greater than a few million years among cluster stars in a very young ...
