Societal Statement on the Role of Occupational Therapy with Survivors of Human Sex Trafficking in the United States
As part of a specialized course, OTD 8340 Wellness and Health Promotion in Occupational Therapy, students from the Nova Southeastern University Entry Level Doctor of Occupational Therapy program, drafted a Societal Statement on the role of occupational therapy with survivors of human sex trafficking in the United States. The students explored the issue of domestic human sex trafficking from an occupational perspective, under the guidance of their professor, Mirtha Montejo Whaley, PhD, OTR/L. As of the publication of this journal, the document is under review by the American Occupational Therapy Association (AOTA
The Three Hundred project: connection between star formation quenching and dynamical evolution in and around simulated galaxy clusters
In this work, we combine the semi-analytic model of galaxy formation and
evolution SAG with the relaxed simulated galaxy clusters from The Three
Hundred project, and we study the link between the quenching of star formation
(SF) and the physical processes that galaxies experience through their
dynamical history in and around clusters. We classify galaxies in four
populations based on their orbital history: recent and ancient infallers, and
backsplash and neighbouring galaxies. We find that per cent of the
current population of quenched galaxies located inside the clusters are ancient
infallers with low or null content of hot and cold gas. The fraction of
quenched ancient infallers increases strongly between the first and second
pericentric passage, due to the removal of hot gas by the action of
ram-pressure stripping (RPS). The majority of them quenches after the first
pericentric passage, but a non-negligible fraction needs a second passage,
specially galaxies with . Recent
infallers represent per cent of the quenched galaxies located inside
the cluster and, on average, they contain a high proportion of hot and cold
gas; moreover, pre-processing effects are the responsible for quenching the
recent infallers prior to infall onto the main cluster progenitor. The per cent of quenched galaxies located around clusters are backsplash
galaxies, for which the combination of RPS acting during a pre-processing stage
and inside the cluster is necessary for the suppression of SF in this
population.Comment: 23 pages, 13 figures + Supplementary material. Accepted for

Strength of hydroxide catalysis bonds between sapphire, silicon, and fused silica as a function of time
Hydroxide catalysis bonds have formed an integral part of ground-based gravitational wave (GW) observatories since the 1990s. By allowing the creation of quasimonolithic fused silica mirror suspensions in detectors such as GEO600 and Advanced LIGO, their use was crucial to the first ever direct detection of gravitational waves. Following these successes, this bonding technique has been included in advanced next generation cryogenic detector designs. Currently, they are used to create quasimonolithic crystalline sapphire suspensions in the KAGRA detector. They are also planned for use in silicon suspensions of future detectors such as the Einstein Telescope. In this paper we report how the strength of hydroxide catalysis bonds evolves over time, and compare the curing rates of bonds as they form between fused silica substrates to those between sapphire to sapphire and silicon to silicon substrates. For bonds between all three types of substrate material we show that newly formed bonds exhibit slightly higher breaking stresses than bonds cured for longer periods of time. We find that the strength stabilizes at
≥
15
MPa
for bonds cured for up to 30 weeks (7 months). This finding is important to future cryogenic GW detector design as it is crucial to ensure the long term integrity of the suspension interfaces. Monitoring the strength of bonds that have been allowed to cure for shorter lengths of time can also shed light on the chemistry of bond formation
The Three Hundred Project: Connection between star formation quenching and dynamical evolution in and around simulated galaxy clusters
In this work, we combine the semi-analytic model of galaxy formation and evolution SAG with the 102 relaxed simulated galaxy clusters from THE THREE HUNDRED project, and we study the link between the quenching of star formation (SF) and the physical processes that galaxies experience through their dynamical history in and around clusters. We classify galaxies in four populations based on their orbital history: recent and ancient infallers, and backsplash and neighbouring galaxies. We find that ∼85 per cent of the current population of quenched galaxies located inside the clusters are ancient infallers with low or null content of hot and cold gas. The fraction of quenched ancient infallers increases strongly between the first and second pericentric passage, due to the removal of hot gas by the action of ram-pressure stripping (RPS). The majority of them quenches after the first pericentric passage, but a non-negligible fraction needs a second passage, specially galaxies with M ≤10^10.5 Msun . Recent infallers represent ∼15 per cent of the quenched galaxies located inside the cluster and, on av erage, the y contain a high proportion of hot and cold gas; moreover, pre-processing effects are responsible for quenching the recent inf allers prior to inf all onto the main cluster progenitor. The ∼65 per cent of quenched galaxies located around clusters are backsplash galaxies, for which the combination of RPS acting during a pre-processing stage and inside the cluster is necessary for the suppression of SF in this population.Fil: Hough, Tomas.

Tackling brain and muscle dysfunction in acute respiratory distress syndrome survivors: National Heart, Lung, and Blood Institute Workshop Report
Acute respiratory distress syndrome (ARDS) is associated with long-term impairments in brain and muscle function that significantly impact the quality of life of those who survive the acute illness. The mechanisms underlying these impairments are not yet well understood, and evidence-based interventions to minimize the burden on patients remain unproven. The National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health assembled a workshop in April 2023 to review the state of the science regarding ARDS-associated brain and muscle dysfunction, to identify gaps in current knowledge, and to determine priorities for future investigation. The workshop included presentations by scientific leaders across the translational science spectrum and was open to the public as well as the scientific community. This report describes the themes discussed at the workshop as well as recommendations to advance the field toward the goal of improving the health and wellbeing of ARDS survivors
