QCD. What else is needed for the Proton Structure Function? [PDF]

open access: yes, 2014
While QCD can provide corrections to the parton distribution function, it cannot produce the distribution. Where is then the starting point for the proton structure function?

Scalable Jet‐Based Fabrication of PEI‐Hydrogel Particles for CO2 Capture

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 7, Issue 6, November 2024.
Energy derived from fossil fuels continues to emit CO2, contributing to a rise in extreme climate events such as floods, wildfires, and deadly heatwaves. Capturing CO2 stands as pivotal strategies in mitigating global warming. In this context, we demonstrate the high‐throughput production of hydrogel‐based CO2‐absorbing particles via liquid jetting ...

Wigner's Spins, Feynman's Partons, and Their Common Ground

open access: yes, 2002
The connection between spin and symmetry was established by Wigner in his 1939 paper on the Poincar\'e group. For a massive particle at rest, the little group is O(3) from which the concept of spin emerges.

Understanding Squeezed States of Light Through Wigner’s Phase-Space

open access: yesMathematics
This paper starts with the transition from classical physics to quantum mechanics which was greatly aided by the concept of phase space. The role of canonical transformations in quantum mechanics is addressed. The Wigner phase-space distribution function

Why do models overestimate surface ozone in the Southeast United States [PDF]

open access: yes, 2016
Ozone pollution in the Southeast US involves complex chemistry driven by emissions of anthropogenic nitrogen oxide radicals (NOx  ≡  NO + NO2) and biogenic isoprene. Model estimates of surface ozone concentrations tend to be biased high in the region and
