Contrary to expectations from upscaling in tropical forests, we found wide sap flow variability across and within individual trees of a homogeneous cohort in a tropical lowland rainforest (10 similar‐sized conspecific trees). Maximum sap flow from simultaneous readings differed up to 14‐fold between trees and averaged 52.5% within individual trees ...

Coherence‐Gated Mirau Interferometry for Single‐Shot Quantitative Phase Imaging and Motion Sensing
This paper presents a compact add‐on module converting a Mirau or other on‐axis interferometer into a single‐shot quantitative phase imaging system using coherence gating and precise optical path matching. Demonstrations include time‐resolved imaging of human cells and streaming red blood cells, visualization of evaporation dynamics in liquid mixtures,

Tectonics and Sliver Motion in Costa Rica: Strain Partitioning Constrained by GNSS Velocities Data
Abstract The tectonic deformation of Costa Rica is controlled by the subduction of the Cocos Plate beneath the Caribbean Plate and the Panama microplate along the Middle America Trench, with oblique convergence in northern Costa Rica to 2024 from 154 permanent stations distributed across Costa Rica to derive for the first time spatially continuous ...

Geophysical Signals Induced by Magma Propagation: Insights From Analog Experiments
Abstract The propagation of magma through the Earth's crust often generates seismic signals and surface deformation, both key indicators of volcanic unrest. While surface deformation is attributed to magma emplacement within fractures, identifying the exact source of the seismic signal remains challenging. Such signals could stem from fracturing at the

GOES‐R Series X‐Ray Sensor (XRS): 2. On‐Orbit Measurements and Calibrations
Abstract An X‐Ray Sensor (XRS) has been onboard each of the National Oceanic and Atmospheric Administration (NOAA) Geostationary Operational Environmental Satellites (GOES) since 1975. XRS measures full‐disk soft X‐ray irradiance in two wavelength bands, 0.05–0.4 nm and 0.1–0.8 nm.

Modeling Hydro‐Ice‐Thermal Dynamics in Open Channels by a Double Layer‐Averaged Model
Abstract Ice processes in open channels are inherently multi‐physics phenomena, characterized by strong coupling of hydrodynamics, heat transfer, and phase‐change dynamics. While many models have been proposed to investigate ice processes, previous studies are often limited by oversimplified representations of flow, presumptions on channel geometry ...
