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.

spotPCR: A Rapid and Efficient Approach for Indexing Individual Template Molecules using Unique Molecular Identifiers.

Low-frequency mutations provide valuable insights in various fields, including drug resistance identification, cancer and infectious disease research. One promising strategy to enhance the sensitivity and specificity of mutation detection is the incorporation of unique molecular identifiers (UMIs) during polymerase chain reaction (PCR) amplification and before deep sequencing. However, conventional methods for UMI incorporation often necessitate multiple labor-intensive steps.

Participation in individual placement support: Ethnoracial differences in the supported employment demonstration.

Objective: The Supported Employment Demonstration (SED), a large, multisite randomized controlled trial, provided evidence-based supported employment to help individuals recently denied Social Security disability benefits for reason of mental illness to gain competitive employment and avoid disability. Monthly, client-level measurement of participation in individual placement and support permitted the first detailed exploration of potential ethnoracial disparities in the IPS participation process, from enrollment to end of follow-along job supports, in a vulnerable population with ready access to the intervention.

Method: Monthly participation data in a subsample of enrollees randomized to receive supported employment enabled decomposition of IPS service participation into take-up, effectiveness, and follow-along support phases, yielding times to participation duration milestones, job start, and end of follow-along supports for 614 non-Hispanic White, non-Hispanic Black, and Hispanic SED enrollees.

stilPCR increases the effective sequencing length of Illumina targeted next-generation sequencing.

Identifying pathogens, resistance-conferring mutations, and strain types through targeted amplicon sequencing is an important tool. However, due to the limitations of short read sequencing, many applications require the division of limited clinical samples. Here, we present stilPCR (single-tube Illumina long read PCR), which allows the generation of hemi-nested amplicons in a single tube, with Illumina indexes and adapters, effectively increasing the Illumina read length without increasing the input requirements of reagents or sample.

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.
