Study of the Ground-State Energies of Some Nuclei Using Hybrid Model
Advances in High Energy Physics, 2021 The quark-quark (QQ) interaction as a perturbed term to the nucleon-nucleon interaction (NN) without any coupling between them is studied in a hybrid model. This model is used to calculate the ground-state energies of 2H1 and 4He2 nuclei.

Understanding the charmed states recently observed by the LHCb and BABAR Collaborations in the quark model [PDF]
, 2014 Comparing the expected spectroscopy in the relativistic quark model and the predicted strong decays in the $^3P_0$ model employing the realistic wave functions from the relativistic quark model with the measured properties of the LHCb and BaBar charmed ...

Linearized Boltzmann-Langevin model for heavy quark transport in hot and dense QCD matter [PDF]
Physical Review C, 2018 In relativistic heavy-ion collisions, the production of heavy quarks at large transverse momenta is strongly suppressed compared to proton-proton collisions.

Berichte zur Wissenschaftsgeschichte, EarlyView.Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

Human flaws and logical tools in engineering
The Canadian Journal of Chemical Engineering, EarlyView.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.

Nucleon structure in a light-front quark model consistent with quark counting rules and data [PDF]
, 2014 Using global fits of valence u and d quark parton distributions and data on quark and nucleon form factors in the Euclidean region, we derive a light-front quark model for the nucleon structure consistent with quark counting rules.

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.

Proto-strange quark stars from density-dependent quark mass model
European Physical Journal C: Particles and FieldsIn this paper, we investigate the evolution of strange quark stars (SQS) from birth as proto-strange quark stars to maturity as stable SQSs at a zero temperature.
