Three-Stage Cross-Scale Relative Geological Time Estimation for 3-D Seismic Data via Deep Learning

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Relative geological time (RGT) estimation is a critical seismic interpretation task for stratigraphic analysis, seismic sedimentology, and reservoir characterization. Deep learning (DL) is an effective RGT estimation approach.

Pharmacological Stimulation of Type 5 Adenylyl Cyclase Stabilizes Heart Rate Under Both Microgravity and Hypergravity Induced by Parabolic Flight

Journal of Pharmacological Sciences, 2012
We previously demonstrated that type 5 adenylyl cyclase (AC5) functions in autonomic regulation in the heart. Based on that work, we hypothesized that pharmacological modulation of AC5 activity could regulate the autonomic control of the heart rate under

Accuracy of next‐generation wireless skin temperature sensors during exercise–heat stress

Experimental Physiology, Volume 111, Issue 8, Page 3463-3479, 1 August 2026.
Abstract Skin temperature is fundamental in characterising human thermoregulatory responses. Wired probes, although accurate, restrict movement and are impractical outside laboratory settings. The iButton (DS1922L; Maxim Integrated, USA) is a widely used wireless alternative but does not meet the precision recommended by ISO 9886 and permits only ...

Tracking Spatiotemporal Mineral Dissolution Through Quantitative Nuclear Magnetic Resonance Signatures

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Mineral dissolution reorganizes pore space through spatiotemporally variable pathways, but non‐invasive tracking remains difficult. We test whether nuclear magnetic resonance (NMR) signatures can diagnose carbonate dissolution by integrating pore‐scale reactive transport simulations with forward modeling of T2 ${T}_{2}$ distributions for face ...

Enhancing hydrogen evolution reaction by harnessing bubble dynamics regulation: Principles, methods, and outlook

Droplet, Volume 5, Issue 3, July 2026.
Bubble dynamics pose critical bottlenecks to hydrogen evolution reaction efficiency, causing active site isolation, increased ohmic resistance, and concentration overpotential, especially at high current densities. This review comprehensively summarizes passive and active bubble manipulation strategies, elucidates their underlying principles, and ...
