Birth Kick Distributions and the Spin-Kick Correlation of Young Pulsars [PDF]

open access: yes, 2007
Evidence from pulsar wind nebula symmetry axes and radio polarization observations suggests that pulsar motions correlate with the spin directions.

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning

open access: yesAdvanced Quantum Technologies, EarlyView.
The use of QML in the realm of nuclear physics at low energy is almost nonexistent. Three examples of the use of quantum computing and quantum machine in nuclear physics are presented: the determination of the phase/shape in nuclear models, the calculation of the ground state energy, and the identification of particles in nuclear physics experiments ...

10,000 Standard Solar Models: a Monte Carlo Simulation

open access: yes, 2005
We have evolved 10,000 solar models using 21 input parameters that are randomly drawn for each model from separate probability distributions for every parameter.

Solar Neutrinos [PDF]

open access: yes, 2012
The study of solar neutrinos has given since ever a fundamental contribution both to astroparticle and to elementary particle physics, offering an ideal test of solar models and offering at the same time relevant indications on the fundamental ...

Human flaws and logical tools in engineering

open access: yesThe Canadian Journal of Chemical Engineering, Volume 103, Issue 8, Page 3512-3520, August 2025.
Abstract This paper explores the limitations of human cognition, especially in engineering research, emphasizing the need for mathematical models and methods to guide decision‐making and theory validation. While human cognition excels in certain tasks, it is prone to biases that can distort our understanding.

Helioseismology and solar neutrinos: an update [PDF]

open access: yes, 2000
We review recent advances concerning helioseismology, solar models and solar neutrinos. Particularly we address the following points: i) helioseismic tests of recent SSMs; ii) predictions of the Beryllium neutrino flux based on helioseismology; iii ...

Polarimetric Wide‐Angle Radar Detects Competing Signatures of Ice Fabric and Structural Firn Anisotropy

open access: yesGeophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract Ice is mechanically and dielectrically anisotropic. The degree of anisotropy evolves dynamically as ice crystals align during deformation into macroscopic patterns termed ice fabric. Radar polarimetry is an emerging tool to detect such patterns, particularly using nadir‐looking antenna geometries sensitive to horizontal anisotropy.

On the photon–classical electromagnetic field relationship

open access: yesAnnals of the New York Academy of Sciences, Volume 1549, Issue 1, Page 11-21, July 2025.
Abstract This paper discusses how the two ways in which the wavefunction of a free‐propagating photon can be introduced—starting from the relativistic energy−momentum relationship or based on the electromagnetic field, in particular on Riemann–Silberstein vectors—are not entirely equivalent since they can lead to different consequences regarding photon
