Laser Wakefield Acceleration of Ions with a Transverse Flying Focus.

Phys Rev Lett

December 2024

Stanford University, Department of Mechanical Engineering, Stanford, California 94305, USA.

The extreme electric fields created in high-intensity laser-plasma interactions could generate energetic ions far more compactly than traditional accelerators. Despite this promise, laser-plasma accelerator experiments have been limited to maximum ion energies of ∼100  MeV/nucleon. The central challenge is the low charge-to-mass ratio of ions, which has precluded one of the most successful approaches used for electrons: laser wakefield acceleration.

Emergent Canonical Spin Tensor in the Chiral-Symmetric Hot QCD.

Phys Rev Lett

December 2024

Stony Brook University, Center for Nuclear Theory, Department of Physics and Astronomy, Stony Brook, New York 11794-3800, USA.

The spin tensor is fundamental to relativistic spin hydrodynamics, but its definition is ambiguous due to the pseudogauge symmetry. We show that this ambiguity can be solved in interacting field theories. We prove that the mean-field limit of a modified Nambu-Jona-Lasinio model with spin-spin interactions is equivalent to nondissipative spin hydrodynamics with a canonical spin tensor.

Z boson events at the Large Hadron Collider can be selected with high purity and are sensitive to a diverse range of QCD phenomena. As a result, these events are often used to probe the nature of the strong force, improve Monte Carlo event generators, and search for deviations from standard model predictions. All previous measurements of Z boson production characterize the event properties using a small number of observables and present the results as differential cross sections in predetermined bins.

A comprehensive study of the angular distributions in the bottom-baryon decays Λ_{b}^{0}→Λ_{c}^{+}h^{-}(h=π,K), followed by Λ_{c}^{+}→Λh^{+} with Λ→pπ^{-} or Λ_{c}^{+}→pK_{S}^{0} decays, is performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of 9  fb^{-1} collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV. The decay parameters and the associated charge-parity (CP) asymmetries are measured, with no significant CP violation observed. For the first time, the Λ_{b}^{0}→Λ_{c}^{+}h^{-} decay parameters are measured.

Light pollution disrupts the natural dark-light rhythmicity of the world and alters the spectral composition of the nocturnal sky, with far-reaching impacts on natural systems. While the costs of light pollution are now documented across scales and taxa, community-level mitigations for arthropods remain unclear. To test two light pollution mitigation strategies, we replaced all 32 streetlights in the largest visitor center in Grand Teton National Park (Wyoming, USA) to allow wireless control over each luminaries' color and brightness.

Implicit and Explicit Race and Weight Biases Among Physician Assistant Preceptors and Trainees.

J Physician Assist Educ

January 2025

Janice Sabin, PhD, MSW, is a research professor of Department of Biomedical Informatics and Medical Education, School of Medicine at University of Washington, Seattle, Washington.

Introduction: As new equity, diversity, and inclusion programs emerge in physician assistant/associate (PA) education, there is a need to assess baseline levels of implicit and explicit biases among PA preceptors' and trainees. The objectives of this study were (1) to measure implicit and explicit race (Black/White) and weight (fat/thin) biases among PA preceptors and trainees and (2) to identify potential gaps in PA preceptor and trainee education.

Methods: This is a cross-sectional study of PA preceptors and trainees from one program operating in several US states; implicit and explicit race and antifat biases and receipt of prior education were measured.

The breadth of the overdose crisis is underestimated because of a lack of quantifying nonfatal overdoses. We estimate the proportion of nonfatal overdoses among all people with HIV (PWH) in British Columbia, Canada, and the prevalence of fatal overdoses among people who had a nonfatal overdose, stratified by sex. A small proportion of PWH who experienced a nonfatal overdose subsequently died of a fatal overdose, signaling opportunities for crucial interventions and treatment to prevent overdose death.

Cell fate decisions during cortical development sculpt the identity of long-range connections that subserve complex behaviors. These decisions are largely dictated by mutually exclusive transcription factors, including CTIP2/Bcl11b for subcerebral projection neurons and BRN1/Pou3f3 for intra-telencephalic projection neurons. We have recently reported that the balance of cortical CTIP2-expressing neurons is altered in a mouse model of DDX3X syndrome, a female-biased neurodevelopmental disorder associated with intellectual disability, autism spectrum disorder, and significant motor challenges.

Unlabelled: Marine protists form complex communities that are shaped by environmental and biological ecosystem properties, as well as ecological interactions between organisms. While all of these factors play a role in shaping protistan communities, the specific ways in which these properties and interactions influence protistan communities remain poorly understood. Fourteen years and 9 months of eukaryotic amplicon (18S-V4 rRNA gene) data collected monthly at the San Pedro Ocean Time-series (SPOT) station were used to evaluate the impacts that environmental and biological factors, and protist-protist interactions had on protistan community composition.
