A Quantum-Mechanical Equivalent-Photon Spectrum for Heavy-Ion Physics [PDF]

open access: yes, 1996
In a previous paper, we calculated the fully quantum-mechanical cross section for electromagnetic excitation during peripheral heavy-ion collisions. Here, we examine the sensitivity of that cross section to the detailed structure of the projectile and ...

Microfluidic electro‐viscoelastic manipulation of extracellular vesicles

open access: yesFEBS Open Bio, EarlyView.
The electro‐viscoelastic manipulation as a potential method for separation of particles based on size. The particles introduced as a sheath flow migrate to the channel center under the influence of simultaneously applied electric field and pressure driven flow.

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

open access: yesFEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

VAIM-CFF: a variational autoencoder inverse mapper solution to Compton form factor extraction from deeply virtual exclusive reactions

open access: yesEuropean Physical Journal C: Particles and Fields
We develop a new methodology for extracting Compton form factors (CFFs) from deeply virtual exclusive reactions such as the unpolarized DVCS cross section using a specialized inverse problem solver, a variational autoencoder inverse mapper (VAIM).

Flavor-dependent radiative corrections in coherent elastic neutrino-nucleus scattering

open access: yesJournal of High Energy Physics, 2021
We calculate coherent elastic neutrino-nucleus scattering cross sections on spin-0 nuclei (e.g. 40Ar and 28Si) at energies below 100 MeV within the Standard Model and account for all effects of permille size.

Measurement of the ttbar Production Cross Section in ppbar Collisions at sqrt(s) = 1.96 TeV [PDF]

open access: yes, 2006
We present a measurement of the top quark pair production cross section in ppbar collisions at sqrt(s)=1.96 TeV using 318 pb^{-1} of data collected with the Collider Detector at Fermilab. We select ttbar decays into the final states e nu + jets and mu nu

Molecular determinants of signal transduction in tropomyosin receptor kinases

open access: yesFEBS Open Bio, EarlyView.
Tropomyosin receptor kinases control critical neuronal functions, but how do the same receptors produce diverse cellular responses? This review explores the structural mechanisms behind Trk signaling diversity, focusing on allosteric modulation and ligand bias.

Dietary nitrate and nitrite protect against doxorubicin‐induced cardiac fibrosis and oxidative protein damage in tumor‐bearing mice

open access: yesFEBS Open Bio, EarlyView.
Chemotherapies such as doxorubicin can have toxic effects on healthy cardiovascular/heart tissue. Following up on a doxorubicin toxicity study in mice without tumors where nitrate water was cardioprotective (lessened toxicity), this study with tumor‐bearing mice undergoing doxorubicin treatment showed no negative effect of nitrate and nitrite on drug ...

Spin Polarization in γd→ $vec{n}$ n→ p

open access: yesEPJ Web of Conferences, 2012
The study of spin observables is an important and active issue in low energy nuclear physics. In this contribution we report our recent calculation on the γd→ $vec{n}$ n→ p reaction at low photon energies.

Measurement of the tt¯ production cross section in pp collisions at s=8 TeV in dilepton final states containing one τ lepton

open access: yesPhysics Letters B, 2014
The top-quark pair production cross section is measured in final states with one electron or muon and one hadronically decaying τ lepton from the process tt¯→(ℓνℓ)(τντ)bb¯, where ℓ=e,μ. The data sample corresponds to an integrated luminosity of 19.6 fb−1
