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.

Basic Science and Pathogenesis.

Background: The accumulation of abnormal tau protein in neurons and glia in the human brain is the defining feature of neurodegenerative diseases known as tauopathies. Progressive supranuclear palsy (PSP), the most common primary tauopathy, is typified by selective vulnerability of dopaminergic neurons and glia in the midbrain leading to an atypical parkinsonian movement disorder. To investigate candidate disease mechanisms underlying PSP, there is a critical need for model systems that more accurately recapitulate the cellular and molecular environment in the human brain.

Basic Science and Pathogenesis.

Background: Progressive supranuclear palsy (PSP) is the most common primary tauopathy, with a constellation of pathological features including 4R-tau positive neurofibrillary tangles and tufted astrocytes. Most PSP cases are sporadic and associated with common structural variation in the 17q21.31 MAPT locus as well as other loci, including EIF2AK3 which is critical for the integrated stress response (ISR).

Living with pain and Parkinson's developing an understanding of the impact, trajectory and pain management needs: a qualitative interview study protocol.

Introduction: Pain is reported as one of the most troubling symptoms for people with Parkinson's (PwP); however, the literature exploring their lived experience of pain and how to manage it is limited. Pain affects PwP at all stages of their condition and can fluctuate and change over time. Therefore, it is pertinent to speak to PwP to understand their experiences of pain to inform the development of tailored behavioural interventions to manage pain.
