Classical transport of electrons and holes in nanoscale devices leads to heating that severely limits performance, reliability, and efficiency. In contrast, recent theory suggests that interband quantum tunneling and subsequent thermalization of carriers with the lattice results in local cooling of devices. However, internal cooling in nanoscale devices is largely unexplored.

Joint gravitational-wave and γ-ray burst (GRB) observations are among the best prospects for standard siren cosmology. However, the strong selection effect for the coincident GRB detection, which is possible only for sources with small inclination angles, induces a systematic uncertainty that is currently not accounted for. We show that this severe source of bias can be removed by inferring the a priori unknown electromagnetic detection probability directly from multimessenger data.

Importance: Care management benefits community-dwelling patients with dementia, but studies include few patients with moderate to severe dementia or from racial and ethnic minority populations, lack palliative care, and seldom reduce health care utilization.
Objective: To determine whether integrated dementia palliative care reduces dementia symptoms, caregiver depression and distress, and emergency department (ED) visits and hospitalizations compared with usual care in moderate to severe dementia.
Design, Setting, And Participants: A randomized clinical trial of community-dwelling patients with moderate to severe dementia and their caregivers enrolled from March 2019 to December 2020 from 2 sites in central Indiana (2-year follow-up completed on January 7, 2023).
Importance: The effectiveness of different approaches to dementia care is unknown.
Objective: To determine the effectiveness of health system-based, community-based dementia care, and usual care for persons with dementia and for caregiver outcomes.
Design, Setting, And Participants: Randomized clinical trial of community-dwelling persons living with dementia and their caregivers conducted at 4 sites in the US (enrollment June 2019-January 2023; final follow-up, August 2023).

Importance: Variation in nicastrin (NCSTN) is associated with a monogenic subtype of hidradenitis suppurativa. Dysregulation of humoral immunity has been suggested as a potential mechanistic link between NCSTN variation and hidradenitis suppurativa. There is a paucity of biomarkers that can predict disease-associated variation.
