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.

Lanthanide-based Metal-organic Frameworks Offering Hydrogen Bonding Cavities: Luminescent Characteristics and Sensing Applications.

This work presents the synthesis and characterization of three isomorphous lanthanide-based metal-organic frameworks (Ln-MOFs) (Ln3+ = Eu (1), Tb (2), and Sm (3)) supported by a pyridine-2,6-dicarboxamide-based linker offering appended arylcarboxylate groups. Single crystal X-ray diffraction studies highlight that these Ln-MOFs present three-dimensional porous architectures offering large cavities decorated with hydrogen bonding (H-bonding) groups. These Ln-MOFs display noteworthy luminescent characteristics.

Harnessing orbital Hall effect in spin-orbit torque MRAM.

Spin-Orbit Torque (SOT) Magnetic Random-Access Memory (MRAM) devices offer improved power efficiency, nonvolatility, and performance compared to static RAM, making them ideal, for instance, for cache memory applications. Efficient magnetization switching, long data retention, and high-density integration in SOT MRAM require ferromagnets (FM) with perpendicular magnetic anisotropy (PMA) combined with large torques enhanced by Orbital Hall Effect (OHE). We have engineered a PMA [Co/Ni] FM on selected OHE layers (Ru, Nb, Cr) and investigated the potential of theoretically predicted larger orbital Hall conductivity (OHC) to quantify the torque and switching current in OHE/[Co/Ni] stacks.

P300 Event-Related Potential: A Surrogate Marker of Cognitive Dysfunction in Parkinson's Disease Patients with Psychosis.

Background And Objectives: Psychosis is one of the major neuropsychiatric non-motor symptoms of Parkinson's disease (PD). Prolonged latency and decreased amplitude of the P300 event-related potential (ERP) is a potential neurophysiologic biomarker of deeper neurocognitive deficits in PD. We aimed to characterize electroencephalogram (EEG)/ERP parameters in PD patients with and without psychosis (PDP and PDNP, respectively), and to determine if such measures could act as endophenotypes for PD-associated psychosis (PDP).
