A revised radiocarbon chronology of Ganj Dareh
, 2021 The absolute chronology of Ganj Dareh is known from some 41 previously published radiocarbon dates, including those on Smith’s original samples of bulk carbon and charcoal (Hole 1987), goat bone collagen (Zeder & Hesse 2000) and human skeletal remains ...

Advanced Science, EarlyView.Pasta is a transcriptomic aging clock built on an age‐shift learning framework and trained on 17 000 samples across 21 datasets. It accurately predicts relative biological age across tissues, platforms, and species, captures stemness‐to‐senescence transitions, and identifies age‐modulatory perturbations.

Advanced Science, EarlyView.A soft hybrid multi‐wavelength PPG wearable acquires neonatal signals. Synchronized PPG and invasive ABP data are segmented into fixed windows. A 1D‐EfficientNet model predicts segment‐level SBP and DBP. Model performance is examined with retrospective subgroup analysis across acquisition conditions.

Advanced Science, EarlyView.Technical limitations often let dominant signals overshadow rare cell types and fine‐grained heterogeneity in spatial transcriptomics. SemanticST, a graph neural network using multi‐semantic graph fusion and a novel min‐cut loss, recovers these subtle patterns.

Advanced Science, EarlyView.Reconstruction of a Co9S8/Co‐Ni3S2 electrocatalyst stabilizes via a leaching‐redeposition dynamic equilibrium of metal ions. Interestingly, the Co‐ion leaching and redeposition play a crucial role in boosting oxygen evolution performance. This endogenous self‐repair cycle continuously offers active sites, allowing the catalyst to maintain superior OER ...

Take a Ride on a Time Machine [PDF]
, 2003 We discuss the possibility to build and operate a time machine, a device that produces closed timelike curves (CTCs). We specify the spacetime structure needed to implement a time machine and assess attempted no-go results against time machines in ...

Metabolic Memory in Cardiovascular Disease: Encoding, Propagation, and Therapeutic Targeting
Advanced Science, EarlyView.Cardiovascular risk often persists after metabolic abnormalities are corrected. This conceptual Review frames such persistence as metabolic memory, encoded through a narrowing therapeutic window from reversible marks to irreversible damage, with continuous input from peripheral organs.

A chronology of turning points in economic activity: Spain 1850-2011 [PDF]
This paper codifies in a systematic and transparent way a historical chronology of business cycle turning points for Spain reaching back to 1850 at annual frequency, and 1939 at monthly frequency.
