On the Wigner-Kirkwood Expansion of the Free Energy and the Evaluation of the Quantum Correction

open access: yesAtoms, 2022
The Wigner-Kirkwood expansion of the quantum correction to the classical free energy is generally said to be in powers of ℏ2 and only its first few terms are presented.

New prompt fission neutron spectra measurements in the 238U(n,f) reaction with a dedicated setup at LANSCE/WNR

open access: yesEPJ Web of Conferences, 2017
A new prompt fission neutron spectra (PFNS) measurement in the 238U(n,f) reaction was performed at LANSCE/WNR facility. Evaluated data show discrepancies on the low (below 1 MeV) and high (above 5 MeV) energy parts in the PFNS for different major and ...

Caries in patients with cleft lip and palate, and their dental rehabilitation. Presentation of a clinical case

open access: yesMexican Journal of Medical Research ICSA, 2016
During the first three months of pregnancy, the parts of the palate and upper lip normally meet. When this union does not occur, the baby will present cleft lip and / or cleft palate. This type of malformation occurs in 1 in every 700 births.

Towards systematic large scale Quasiparticle Random-Phase Approximation calculations with covariant and chiral interactions [PDF]

open access: yesEPJ Web of Conferences
One of the main methods used to microscopically describe collective states in atomic nuclei is the quasiparticle random-phase approximation (QRPA). However, due to its high computational cost, systematic studies covering the full nuclear chart are rare ...

Spectroscopic limits of diamond anvils to 520 GPa and projected bandgap closure

open access: yesNature Communications
Diamond anvils serve as optical windows in static ultrahigh-pressure experiments, now reaching the terapascal regime. However, they exhibit poorly understood changes in their optical properties under multimegabar pressure.

Non local microscopic potentials for calculation of scattering observables of nucleons on deformed nuclei

open access: yesEPJ Web of Conferences, 2017
Direct reactions on deformed nuclei such as actinides are best studied with the coupled channel (CC) formalism and a complex coupling scheme. With all significant progress that has been made in describing target nuclei with mean field and beyond ...

Risk factors associated with neonatal sepsis of nosocomial origin in patients at a Mexican Hospital

open access: yesMexican Journal of Medical Research ICSA, 2012
Nosocomial neonatal sepsis (NNS) is one of the principal causes of childhood morbidity and mortality and has a large impact on public health. Therefore, our objective was to determine the prevalence and risk factors associated with NNS in patients at ...

Toroidal diamond anvil cell for detailed measurements under extreme static pressures

open access: yesNature Communications, 2018
Extreme static pressures exceeding a million atmospheres exist in a variety of natural environments, but obtaining such pressures in a laboratory is still a challenge.

Fission description: First steps towards a full resolution of the time-dependent Hill-Wheeler equation

open access: yesEPJ Web of Conferences, 2017
Dynamical description of low energy fission is, in our full microscopic approach, decomposed in two steps. In the first step we generate the Potential Energy Surface (PES) of the compound system we want to describe with the Hartree-Fock-Bogoliubov (HFB ...
