Coherent Beam-Beam Tune Shift of Unsymmetrical Beam-Beam Interactions with Large Beam-Beam Parameter [PDF]

open access: yesPhysical Review E, 2004
Coherent beam-beam tune shift of unsymmetrical beam-beam interactions was studied experimentally and numerically in HERA where the lepton beam has a very large beam-beam parameter (up to $\xi_y=0.272$).

Beam-Beam Effects

open access: yes, 2016
One of the most severe limitations in high-intensity particle colliders is the beam-beam interaction, i.e. the perturbation of the beams as they cross the opposing beams.

Anomalous beam diffusion near beam-beam synchro-betatron resonances [PDF]

open access: yesPhysical Review Special Topics - Accelerators and Beams, 2012
The diffusion process near low order synchro-betatron resonances driven by beam-beam interactions at a crossing angle is investigated. Macroscopic observables such as beam emittance, lifetime and beam profiles are calculated.

“Mother” Matters: How changing language can compromise breastfeeding support

open access: yesWorld Nutrition, 2021
The increasing pressure to avoid the word "mother" by those in the lactation world hoping to achieve greater inclusivity can undermine breastfeeding advocacy.

Bottom-up fabrication of FeSb2 nanowires on crystalline GaAs substrates with ion-induced pre-patterning

open access: yesFrontiers in Physics, 2023
In recent decades, nanostructuring has become one of the most important techniques to design and engineer functional materials. The properties of nanostructured materials are influenced by the interplay of its instrinsic bulk properties and the ...

Neuronal junctophilins recruit specific CaV and RyR isoforms to ER-PM junctions and functionally alter CaV2.1 and CaV2.2

open access: yeseLife, 2021
Junctions between the endoplasmic reticulum and plasma membrane that are induced by the neuronal junctophilins are of demonstrated importance, but their molecular architecture is still poorly understood and challenging to address in neurons.

Coherent beam-beam interaction with four colliding beams [PDF]

open access: yesPhysical Review E, 1995
The coherent beam-beam interaction in the absence of Landau damping is studied with a computer simulation of four space-charge-compensated colliding beams. Results are presented for the modes, phase space structures, widths, and growth rates of coherent beam-beam resonances.

Frictional interactions for non‐localized beam‐to‐beam and beam‐inside‐beam contact [PDF]

open access: yesInternational Journal for Numerical Methods in Engineering, 2021
AbstractThis contribution presents the extensions of beam‐to‐beam and beam‐inside‐beam contact schemes of the same authors towards frictional interactions. Since the schemes are based on the beams' true surfaces (instead of surfaces implicitly deduced from the beams' centroid lines), the presented enhancements are not only able to account for ...

Cytosine base editors with minimized unguided DNA and RNA off-target events and high on-target activity

open access: yesNature Communications, 2020
Cytosine base editors have been reported to induce off-target mutations in DNA and RNA. Here the authors identify next-generation CBEs with reduced guide-independent off-target editing profiles and retain high on-target editing activity.
