Polarized Deformed Nuclei Studied via Coincidence Polarized Electron Scattering: The case of 21 Ne

, 1993
Coincidence reactions of the type $\svec{A}(\svec{e},e'N)B$ involving the scattering of polarized electrons from deformed polarized targets are discussed within the context of the plane--wave impulse approximation.

Hadron Helicity Violation in Exclusive Processes: Quantitative Calculations in Leading Order QCD [PDF]

, 1995
We study a new mechanism for hadronic helicity flip in high energy hard exclusive reactions. The mechanism proceeds in the limit of perfect chiral symmetry, namely without any need to flip a quark helicity. The fundamental feature of the new mechanism is

A new calculation for D(e,e'p)n at GeV energies [PDF]

, 2008
We perform a fully relativistic calculation of the D(e,e'p)n reaction in the impulse approximation. We employ the Gross equation to describe the deuteron ground state, and we use the SAID parametrization of the full NN scattering amplitude to describe ...

AI in chemical engineering: From promise to practice

AIChE Journal, EarlyView.
Abstract Artificial intelligence (AI) in chemical engineering has moved from promise to practice: physics‐aware (gray‐box) models are gaining traction, reinforcement learning complements model predictive control (MPC), and generative AI powers documentation, digitization, and safety workflows.

Calculation of laser induced impulse based on the laser supported detonation wave model with dissociation, ionization and radiation

AIP Advances, 2014
In the laser intensity range that the laser supported detonation (LSD) wave can be maintained, dissociation, ionization and radiation take a substantial part of the incidence laser energy.

Assessment of knowledge integration in student learning of momentum

Physical Review Physics Education Research, 2020
Momentum is a foundational concept in physics. Although it is often taught in introductory mechanics courses, there are a limited number of studies on this topic in the literature. The results from these studies have consistently shown that students have
