A multi‐institutional multi‐methods analysis of jeopardy systems in academic hospital medicine

open access: yesJournal of Hospital Medicine, EarlyView.
Abstract Background Hospital medicine programs use backup (“jeopardy”) systems to cover unexpected staffing gaps, but little is known about their structures or optimal practices. Objectives To describe jeopardy structures, assess clinician perceptions, and identify potential approaches across a broad sample of hospital medicine groups.

Opium trade and use during the Late Bronze Age: Organic residue analysis of ceramic vessels from the burials of Tel Yehud, Israel

open access: yesArchaeometry, EarlyView., 2022
Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...

Ultralight, Washable, and Antibacterial Ultrafine Fiber Sponges by Direct Electrospinning for High‐Performance Warmth Retention

open access: yesMacromolecular Materials and Engineering, EarlyView.
In this study, a facile approach for fabricating washable and antibacterial PS/PU fibrous sponges by direct electrospinning is demonstrated. The obtained fiber sponge exhibits lightweight (3.89 mg cm−3), significant mechanical durability, warmth retention performance (23.77 mW m−¹ K−¹), and 98.9% antibacterial efficiency after 10 washing cycles, making

Electrospinning Using AC Electric Fields

open access: yesMacromolecular Rapid Communications, EarlyView.
This review covers the state‐of‐the‐art of process of alternating field electrospinning (AFES, a.k.a. AC‐electrospinning). Although tremendous progress is achieved in the development of AC‐electrospinning over the last 10 years, this technique remains uncommon. The synopses of AFES process concepts, parameters, spinneret designs, benefits and obstacles,

Deep learning accelerated the discovery of multi‐principal element alloys with various strength‐toughness trade‐offs

open access: yesMaterials Genome Engineering Advances, EarlyView.
Coupling deep generative models with Pareto optimization, we uncover eight multiprincipal element alloys that outperform existing strength–toughness records after only three design–test cycles, showcasing a rapid data‐efficient route to balanced‐property alloy discovery across high‐dimensional composition spaces.
