摘要：Resting heart rate (RHR) is a key biomarker of cardiovascular health and mortality1, 2-3, but passively tracking it longitudinally generally requires a wearable device, limiting its availability. Here we present passive heart-rate monitoring (PHRM), a deep-learning system that uses facial video-based photoplethysmography for passive measurements of heart rate (HR) and RHR during everyday smartphone interactions. Our system was developed using 192,353 videos from 485 participants and validated ...

摘要：Over geological time, the growth of the ocean floor involves magmatic and tectonic extension1 at mid-ocean ridges (MORs). Because seismogeodetic monitoring of these submarine plate boundaries remains challenging2, 3, 4, 5, 6-7, little is known about how these systems operate on yearly timescales. Here we report the first, to our knowledge, in situ observation of a rifting event at a MOR segment that combines hydroacoustic, direct-path ranging and bottom-pressure measurements, with repeated sea...

摘要：Lithium-metal solid-state batteries offer advantages of high energy density and improved safety compared with lithium-ion batteries1,2. However, solid-state batteries fail through short-circuiting even at low charging rates (less than 1 mA cm-2) due to lithium dendrite initiation and propagation3, 4-5. The location of dendrite initiation is under debate, particularly regarding whether initiation occurs within the interior of the solid electrolyte6, 7, 8-9 or at the surface10, 11, 12, 13-14. He...
