How to correct Ehrenfest nonadiabatic dynamics in open quantum systems: Ehrenfest plus random force (E + σ) dynamics.

One key challenge in the study of nonadiabatic dynamics in open quantum systems is to balance computational efficiency and accuracy. Although Ehrenfest dynamics (ED) is computationally efficient and well-suited for large complex systems, ED often yields inaccurate results. To address these limitations, we improve the accuracy of the traditional ED by adding a random force (E + σ).

The effect of increased vascular afterload measures on flow rate and survival in severe aortic stenosis.

Aims: Although an association between the systemic circulation and transaortic flow rate (TFR) is frequently hypothesized in patients with aortic stenosis (AS), it has not been demonstrated previously. We sought to explore the relationship between blood pressure (BP), vascular afterload measures, clinical history of hypertension, TFR, and survival in patients with severe AS (aortic valve area ≤ 1 cm²).

Methods And Results: We studied 323 patients ≥ 65 years (110 prospective, 213 registry analysis) who underwent transcatheter aortic valve replacement over a 5-year period.

Broadband wireless battery-free acoustic identification tags for high data-rate underwater backscatter communication.

Developing persistent and smart underwater markers is critical for improving navigation accuracy and communication capabilities of autonomous underwater vehicles (AUVs). A wireless acoustic identification tag, which uses a piezoelectric transducer tuned in the broadband ultrasonic range (200-500 kHz), was experimentally demonstrated to achieve highly efficient power transfer (source-to-tag electrical power efficiency of >2% at 6 m) and concurrent high data rate and backscatter level communication (>83.3 kbit s-1, >170 dB sound pressure level at 6 m) with potential operating range ≈ 10 m based on analytical extrapolations.

Biological, linguistic, and individual factors govern voice qualitya).

Voice quality serves as a rich source of information about speakers, providing listeners with impressions of identity, emotional state, age, sex, reproductive fitness, and other biologically and socially salient characteristics. Understanding how this information is transmitted, accessed, and exploited requires knowledge of the psychoacoustic dimensions along which voices vary, an area that remains largely unexplored. Recent studies of English speakers have shown that two factors related to speaker size and arousal consistently emerge as the most important determinants of quality, regardless of who is speaking.

Social determinants of health and health outcomes in older cancer survivors.

Purpose Of The Review: Today, two-thirds of all cancer survivors are at least 65 years old. Older cancer survivors have complex care needs, and addressing their social determinants of health (SDoH) is critical for improving and managing survivorship outcomes for this uniquely vulnerable population, yet research specifically examining these associations remains limited and emergent. To this end, we describe the emergent body of evidence on the associations between SDoH domains and older cancer survivors' outcomes.

Variation and assembly mechanisms of skin and cave environmental fungal communities during hibernation periods.

Animal skin acts as the barrier against invasion by pathogens and microbial colonizers. Environmental microbiota plays a significant role in shaping these microbial communities, which, in turn, have profound implications for host health. Previous research has focused on characterizing microorganisms on bats' skin and in their roosting environments, particularly bacterial communities.

Victimisation in other- and self-directed violence as a function of ethnicity and primary diagnosis among inpatients with serious mental illness.
