Covariant and heavy quark symmetric quark models [PDF]

Physical Review D, 1994
There exist relativistic quark models (potential or MIT-bag) which satisfy the heavy quark symmetry (HQS) relations among meson decay constants and form factors. Covariant construction of the momentum eigenstates, developed here, can correct for spurious center-of-mass motion contributions.Proton form factor and M1 transitions in quarkonia are ...

Search for the QCD Critical Point with Fluctuations of Conserved Quantities in Relativistic Heavy-Ion Collisions at RHIC

EPJ Web of Conferences, 2017
Fluctuations of conserved quantities are predicted to be sensitive observables to probe the QCD phase transition and critical point in heavy-ion collisions.

Design of Proprietary Frameworks for Neural Models: Methodology and Best Practices

Journal of Advanced Computing Systems
The creation of proprietary frameworks for the development of neural models is essential to meet specific needs that generic frameworks cannot address. This article examines the key stages in the design of these frameworks and offers best practices for ...

Generalized Beth–Uhlenbeck Entropy Formula From the Φ‐Derivable Approach

Contributions to Plasma Physics, EarlyView.
ABSTRACT We derive a generalized Beth–Uhlenbeck formula for the entropy of a dense fermion system with strong two‐particle correlations, including scattering states and bound states. We work within the Φ‐derivable approach to the thermodynamic potential.

Open heavy flavor measurements at STAR

EPJ Web of Conferences, 2015
In relativistic heavy ion collisions at RHIC, heavy quarks are expected to be created from initial hard scatterings. Since heavy quarks have large masses, long life time, and negligible annihilation due to their small population, the number of heavy ...

Exercise limitations in amyloid cardiomyopathy assessed by cardiopulmonary exercise testing—A multicentre study

ESC Heart Failure, Volume 12, Issue 2, Page 1326-1335, April 2025.
Abstract Aims Amyloid cardiomyopathy is caused by the deposition of light chain (AL) or transthyretin amyloid (ATTR) fibrils, that leads to a restrictive cardiomyopathy, often resulting in heart failure (HF) with preserved or reduced ejection fraction.

Performance of pyDock in 8th CAPRI: Energy‐Based Scoring Applied to Docking and AlphaFold Models

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The 8th CAPRI edition has shown a significant evolution in the field of protein–protein complex structure prediction. We have participated in all 11 targets proposed in this edition, involving domain‐domain, protein–protein, protein‐peptide, and protein‐DNA interactions, including homo‐ and hetero‐meric interfaces.
