Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Long-Range and Coupled Rotor Dynamics in NO-MIL-53(Al) by Classical Molecular Dynamics.

By tuning the steric environment and free pore space in metal-organic frameworks, a large variety of rotor dynamics of the organic linkers can appear. Nitrofunctionalized MIL-53 is a terephthalate-linker-based MOF that shows coupled rotor dynamics between the neighboring linkers along the pore direction. Here, we use classical molecular dynamics up to 6 × 2 × 2 supercells to investigate the range of the correlated linker dynamics.

Artificial Gold Enzymes Using a Genetically Encoded Thiophenol-Based Noble-Metal-Binding Ligand.

Incorporating noble metals in artificial metalloenzymes (ArMs) is challenging due to the lack of suitable soft coordinating ligands among natural amino acids. We present a new class of ArMs featuring a genetically encoded noble-metal-binding site based on a non-canonical thiophenol-based amino acid, 4-mercaptophenylalanine (pSHF), incorporated in the transcriptional regulator LmrR through stop codon suppression. We demonstrate that pSHF is an excellent ligand for noble metals in their low oxidation states.

A qualitative study of young workers' experience of the psychosocial work environment and how this affects their mental health.

Background: The evidence base for the relationship between psychosocial work factors and mental health focuses primarily on the general working population but little is known about young workers. The aim of this qualitative study is to identify psychosocial work factors that affect the mental health of young workers, with a focus on (1) novel factors of the psychosocial work environment that are relevant for young workers but have not been described in the literature and (2) experiences of psychosocial work factors associated with mental health that are specific to and typical for young workers.

Methods: Semi-structured interviews were held with 36 workers aged up to 30.

Search for the Exclusive W Boson Hadronic Decays W^{±}→π^{±}γ, W^{±}→K^{±}γ and W^{±}→ρ^{±}γ with the ATLAS Detector.

A search for the exclusive hadronic decays W^{±}→π^{±}γ, W^{±}→K^{±}γ, and W^{±}→ρ^{±}γ is performed using up to 140  fb^{-1} of proton-proton collisions recorded with the ATLAS detector at a center-of-mass energy of sqrt[s]=13  TeV. If observed, these rare processes would provide a unique test bench for the quantum chromodynamics factorization formalism used to calculate cross sections at colliders. Additionally, at future colliders, these decays could offer a new way to measure the W boson mass through fully reconstructed decay products.
