Spatiotemporal terahertz emission nanoscopy of spintronic photocurrent
Abstract Capturing ultrafast spin and charge photocurrents on nanoscopic scales is essential for fundamental research in physics and engineering, as well as for future applications, such as novel spin-orbitronic devices. Accessing the fundamental dynamics driven by changes in electronic energy, linear momentum, and angular momentum requires probing at its native spatiotemporal scales: femtoseconds and nanometers.

Comprehensive chemical characterization of Alcoholic beverages and discovery of bioactive components regulating alcohol metabolism enzyme activities
Abstract Baijiu is a traditional Chinese alcoholic beverages with significant dietary and medicinal value, including sauce, strong, light and rice four primary flavors. Baijiu contains an exceptionally complex mixture of volatile and non-volatile compounds that contribute to its diverse flavor profiles and potential biological activities. This study employed HS-SPME-Arrow-GC-MS and UPLC-QTOF-MS to systematically analyze four major Baijiu flavor types.

Green tea catechin EGCG attenuates hippocampal atrophy and cognitive impairment in obesity via autophagy signaling
|
Abstract Obesity is prevalent and linked to cognitive impairment via hippocampal atrophy and insulin resistance. Here, we investigated whether the primary catechin of green tea, epigallocatechin‑3‑gallate (EGCG), could attenuate this neuropathology. Epidemiological analysis of UK Biobank adults with obesity provided an initial clue, showing a positive linear trend between green tea intake and hippocampal volume (p = 0.07).

An automatic, rapid and accurate method for the annotation of tumor components on whole slide images
ABSTRACT Annotated pathology datasets are the cornerstone for developing computational pathology. However, the intrinsic complexity of pathology data often results in a scarcity of large, manually annotated datasets. To address this challenge, a rapid, accurate, and automatic method for annotating tumor cells is essential for advancing the field of computational pathology. Here, we introduce a novel annotation technology.

Efficient and stable n-type sulfide overall water splitting with separated hydrogen production - Nature Communications
Abstract N-type sulfide semiconductors are promising photocatalysts due to their broad visible-light absorption, facile synthesis and chemical diversity. However, photocorrosion and limited electron transport in one-step excitation and solid-state Z-scheme systems hinder efficient overall water splitting. Liquid-phase Z-schemes offer a viable alternative, but sluggish mediator kinetics and interfacial side reactions impede their construction.

Data-driven Model Discovery and Model Selection for Noisy Biological Systems
Xiaojun Wu, MeiLu McDermott, Adam L MacLean. Abstract Biological systems exhibit complex dynamics that differential equations can often adeptly represent. Ordinary differential equation models are widespread; until recently their construction has required extensive prior knowledge of the system. Machine learning methods offer alternative means of model construction: differential equation models can be learnt from data via model discovery using sparse identification of nonlinear dynamics (SINDy).

Temporal compressive edge imaging enabled by a lensless diffuser camera
Lensless imagers based on diffusers or encoding masks enable high-dimensional imaging from a single-shot measurement and have been applied in various applications. However, to further extract image information such as edge detection, conventional post-processing filtering operations are needed after the reconstruction of the original object images in the diffuser imaging systems.
