Uncertainty evaluation of nuclear reaction model parameters using integral and microscopic measurements. Covariances evaluation with CONRAD code

open access: yesEPJ Web of Conferences, 2010
In the [eV;MeV] energy range, modelling of the neutron induced reactions are based on nuclear reaction models having parameters. Estimation of co-variances on cross sections or on nuclear reaction model parameters is a recurrent puzzle in nuclear data ...

Loss of Stat3 in Prx1+ Progenitors Impairs Molar Root Development

open access: yesAdvanced Biology, EarlyView.
Stat3 critically regulates mandibular first molar and alveolar bone morphogenesis. Conditional ablation of Stat3 disrupts the osteogenic capacity of Prx1+ mesenchymal progenitors, as evidenced across in vivo and in vitro models. Abstract Signal Transducer and Activator of Transcription 3 (Stat3) acts as a central transcriptional modulator coordinating ...

Primary Human Tissue Models for Metabolic Dysfunction‐Associated Liver Disease ‐ toward Streamlining Drug Discovery with Patient‐Derived Assays

open access: yesAdvanced Biology, EarlyView.
The review provides a critical up‐to‐date overview of the current landscape of human in vitro models for fatty liver disease, including spheroids, organoids, organ‐on‐a‐chip systems, bioprinted liver constructs and precision‐cut liver slices. Their utility for faithfully modeling different stages of MASLD and MASH are evaluated and their compatibility ...

A Spatially Resolved View on the Aging Substantia nigra: An Exploratory Proteomic Study

open access: yesAdvanced Biology, EarlyView.
Although aging is the most important risk factor for several neurodegenerative diseases, the molecular effects of physiological aging are still understudied. By applying spatially‐resolved proteomic analyses of the human substantia nigra pars compacta, alterations in vesicular trafficking and mitochondrial proteins are observed, as well as reduced ...

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Neutron capture reaction cross-section of 79Se through the 79Se(d,p) reaction in inverse kinematics

open access: yesPhysics Letters B
γ emission probabilities from unbound states in 78,80Se, populated by a neutron-transfer reaction (d,p) on 77,79Se nuclei in inverse kinematics, were measured by directly detecting reaction residues.

Elastic and total reaction cross sections of oxygen isotopes in Glauber theory

open access: yes, 2008
We systematically calculate the total reaction cross sections of oxygen isotopes, $^{15-24}$O, on a $^{12}$C target at high energies using the Glauber theory.
