Physics at future accelerators [PDF]

open access: yesEPJ Web of Conferences
New high-energy colliders are currently under discussion, and will potentially be operational after the completion of the LHC/HL-LHC program. They could open up scenarios for the exploration of the Standard Model of fundamental interactions and its ...

Effective collision strengths for transitions in singly ionized nitrogen [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2004
The R-matrix method has been used to calculate effective collision strengths for the electron-impact excitation of the carbon-like ion N II. The lowest 23 LS target states are included in the expansion of the total wavefunction, consisting of the nine n = 2 states with configurations 2 s 22p 2 and 2s2p 3 , along with 14 n = 3 states with configuration

Search for flavour-changing neutral-current interactions of a top quark and a gluon in pp collisions at $$\sqrt{s}=13$$ s = 13  TeV with the ATLAS detector

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
A search is presented for the production of a single top quark via left-handed flavour-changing neutral-current (FCNC) interactions of a top quark, a gluon and an up or charm quark.

Energy levels, oscillator strengths, and effective collision strengths for transitions in Fe XIV [PDF]

open access: yesJournal of Physics: Conference Series, 2009
In this paper we report atomic data, namely energy levels, radiative rates, lifetimes, collision strengths, and excitation rate coefficients, for transitions among 162 levels of the (1s22s22p6) 3s23p, 3s3p2, 3s23d, 3p3, 3s3p3d, 3p23d, 3s3d2, 3p3d2, 3d3, 3s3p4s, and 3s24l configurations of Fe XIV.

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

open access: yesFEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral
