Advanced Science, EarlyView.A physics‐based framework resolving graphite phase‐separation dynamics establishes a predictive, degradation‐aware fast‐charging methodology for commercial Li‐ion batteries. The resulting model‐informed protocol achieves 20%–80% state‐of‐charge in 14 min while matching the long‐term degradation of a commercial 25‐minute EV strategy.

GLS1 Orchestrates Exosome‐Mediated Tumor‐Endothelial Communication to Facilitate Angiogenesis
Advanced Science, EarlyView.This study reveals a previously unappreciated, non‐metabolic function of GLS1 in the control of tumor angiogenesis via exosome‐mediated CAV1‐TNC signaling, indicating that therapeutic targeting of GLS1 may offer a dual benefit by simultaneously suppressing tumor metabolic activity and angiogenic processes in head and neck cancer. ABSTRACT Glutaminase 1

The Repurchasing Behaviors of Taiwanese Individual Investors
, 2007 這篇論文利用投資人整體投資次數以及投資人比例兩種角度，來探討台灣投資人的三種重購行為，(1)是否會重購之前賣出時獲利的股票；(2)是否會重購賣出後價格下跌的股票以及(3)是否會重購目前持有的投資組合中，價格下跌的股票，根據研究發現，投資人確實有這些傾向；並且取1998年至2001年的台灣股票市場加權指數資料發現，投資人在市場景氣低迷時，會更傾向於做這些重購動作。 另外根據研究顯示，投資人無法從這些重購行為中獲利，而在利用回歸分析後，也找出一些從事這些重購行為投資人的特性。This paper ...

Metasurface‐Enabled Active‐Like Passive Radar
Advanced Science, EarlyView.A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...

Trophic Diversity in Duckweed: Mixotrophy, More Than the Sum of its Extremes
Advanced Science, EarlyView.In the context of rising DOC in aquatic environments, mixotrophic duckweed may impact carbon cycling by acting as either a carbon sink, as they absorb CO2 through photosynthesis, or a carbon source, as they release CO2 through respiration of absorbed DOC, which depends on DOC concentration, light availability, temperature, and other environmental ...

Advanced Science, EarlyView.A continuous conductivity gradient is formed in a porous MXene/melamine foam via directional evaporation, thereby improving impedance matching and enhancing electromagnetic attenuation. The resulting monolithic composite delivers absorption‐dominant EMI shielding with ultralow reflection, offering a simple route toward lightweight EMI shielding ...
