We are midway through a milestone year for nursing, and we have just finished a month-long celebration of Florence Nightingale's 200th birthday. The party may be over, but the work continues. How do we keep the momentum going, not just for 2020, but well beyond? In this month's Magnet Perspectives column, we explore ways to continue to promote the Year of the Nurse through its 3 anchors: nursing excellence, leadership, and innovation. We also take a look at how Magnet organizations stay relevant in these areas, by infusing lifelong learning, evidence-based practice, and clinical inquiry into the culture and making every day an opportunity to celebrate and elevate nursing.

How mariculture expansion is dewilding the ocean and its inhabitants.
Sci Adv
October 2024
Department of Environmental Studies, New York University, 285 Mercer Street, New York, NY 10003, USA.
Article Synopsis
- The rise of mariculture, or the farming of aquatic organisms in oceans, is gaining traction, promising economic and nutritional benefits but also presenting significant risks.
- Environmental degradation, negative effects on wildlife, issues with captivity, and shifts in human perceptions of nature collectively create what is termed "dewilding."
- A systematic review of recent literature reveals that while many impacts of mariculture are documented, the focus on issues like captivity and conceptual changes is notably less, highlighting the need for further research to inform future decisions.
Effect of Chlorination on the Shape Resonance Spectrum of CHBr and CClBr Molecules in Collisions with Electrons.

Departamento de Física, Universidade Federal do Paraná, Caixa Postal 19044, 81531-980 Curitiba, Paraná, Brazil.
In this work, we present a theoretical study of elastic electron scattering by the CHBr and CClBr molecules using the Schwinger multichannel method. Through the scattering amplitudes computed at the static-exchange and static-exchange plus polarization levels of approximation, we have obtained integral, momentum transfer, and differential cross sections for energies ranging from 0 to 20 eV. For both systems, the resonance spectrum was identified in the cross sections and characterized with basis on the analysis of the eigenvalues and eigenvectors obtained by diagonalization of the scattering Hamiltonian.

The concept of randomized measurements on individual particles has proven to be useful for analyzing quantum systems and is central for methods like shadow tomography of quantum states. We introduce collective randomized measurements as a tool in quantum information processing. Our idea is to perform measurements of collective angular momentum on a quantum system and actively rotate the directions using simultaneous multilateral unitaries.

We investigate the collective dynamics of thermoresponsive polymer poly(-isopropylmethacrylamide) (PNIPMAM) in aqueous solution and in water/methanol mixtures in the one-phase region. In neat water, the polymer concentration is varied in a wide range around the overlap concentration *, that is estimated at 23 g L. Using dynamic light scattering (DLS), two decays ("modes") are consistently observed in the intensity autocorrelation functions for = 2-150 g L with relaxation rates which are proportional to the square of the momentum transfer.

We perform classical-statistical real-time lattice simulations to compute real-time spectral functions and momentum broadening of quarks in the presence of strongly populated non-Abelian gauge fields. Based on a novel methodology to extract the momentum broadening for relativistic quarks, we find that the momentum distribution of quarks exhibit interesting nonperturbative features as a function of time due to correlated momentum kicks it receives from the medium, eventually going over to a diffusive regime. We extract the momentum diffusion coefficient for a mass range describing charm and bottom quarks and find sizable discrepancies from the heavy-quark limit.
