Superradiance and Broadband Emission Driving Fast Electron Dephasing in Open Quantum Systems

open access: yesAdvanced Science, EarlyView.
We uncover the physical origin of ultrafast electron dephasing in solid‐state high‐harmonic generation by simulating the Lindblad equation for the dissipative Hubbard model. Coexistence of Dicke superradiance and broadband emission is revealed, whose destructive interference shortens the effective scattering time and provides a unified picture of ...

Highly Efficient Extraction of 212 Pb/212Bi from the Decay Chain of 232Th‐Based on Anion Exchange in Bromide Medium

open access: yesAdvanced Science, EarlyView.
This work provides an effective strategy for selectively extracting 212Pb and 212Bi from the decay chain of 232Th as well as its mechanism illustration. Using the novel strategy, 2.07 MBq of 212Pb is successfully separated from 232Th and its daughters, which enables the supply of 212Pb/212Bi directly from the abundant natural thorium resource to be ...

The mtDNA D-Loop Legacy of Cattle: Fluctuations in Diversity from the Neolithic to Early Medieval Times in Switzerland

open access: yesDiversity, 2023
Fluctuations in the size of taurine cattle (Bos taurus) have been regularly demonstrated using archaeozoological data from across time and space in Europe, and have been linked to cultural, social and economic changes, but little is known about whether ...

Comparing the Latent Features of Universal Machine‐Learning Interatomic Potentials

open access: yesAdvanced Intelligent Systems, EarlyView.
This study quantitatively assesses how universal machine‐learning interatomic potentials encode the chemical space into latent features, showing unique model‐specific representations with high cross‐model reconstruction errors. It explores how training datasets, protocols, and targets affect these encodings.

Mental health service use among Filipino American and Korean American young adults during the COVID‐19 pandemic

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Despite the heightened mental health challenges amid rising Anti‐Asian sentiment, Asian Americans have significantly underutilized mental health services, a trend that persisted even before the COVID‐19 pandemic. Although considerable efforts have been made to understand how various factors are related to mental health service use in this ...

Trabecular bone ontogeny of the human talus

open access: yesThe Anatomical Record, EarlyView.
Abstract Studies of trabecular ontogeny may provide insight into the factors that drive healthy bone development. There is a growing understanding of how the juvenile skeleton responds to these influences; however, gaps in our knowledge remain. This study aims to identify ontogenetic trabecular patterns and regional changes during development within ...

Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

open access: yesThe Anatomical Record, EarlyView.
Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...

Integrating whole‐bone and regional analyses to understand human scapular growth

open access: yesThe Anatomical Record, EarlyView.
Abstract This study investigates ontogenetic changes in human scapular morphology using three‐dimensional geometric morphometrics with whole‐bone and region‐specific analyses. The aim is to evaluate whether the scapula follows a regular developmental pattern and whether its functionally distinct components, the scapular spine (SS) and glenoid fossa ...
