Repeatable Velocity Fine Structure of Lightning K‐Leaders From a Single VHF Interferometer Made Three‐Dimensional

Abstract K‐processes re‐illuminate lightning channels at speeds of order 10 7 m s −1 , but measuring their three‐dimensional (3‐D) propagation velocity has required multi‐station systems available at few sites. An error‐isomorphism range inversion upgrades a single very‐high‐freq...

Pick Aggregator: A Multimodel Ensemble of Machine Learning Pickers to Generate an Onshore–Offshore Seismic Catalog for Puerto Rico and the Virgin Islands

Abstract Offshore seismic swarms north of Puerto Rico and the Virgin Islands remain poorly characterized due to limited azimuthal coverage from the inland Puerto Rico Seismic Network (network code PR). Here, we integrate data from six U.S. Geological Survey (USGS) ocean-bottom se...

Integrating smartrock and seismic monitoring to investigate bedload transport dynamics during rapid increase of stages in ephemeral streams

Abstract. Bedload transport dynamics during rapid increases of stage remain poorly constrained, particularly in ephemeral streams where such conditions are common. We combined two cutting-edge monitoring techniques – smartrocks and seismic measurements – to investigate bedload tr...

Geometry Representation, Not Solver Choice, Dominates Cross-Code Permeability Predic-tions for Biomimetic and TPMS Heat Pipe Wicks

Abstract Pore-scale permeability predictions for candidate heat pipe wicks are routinely reported from a single solver on a single geometry representation, leaving solver error, discretization error, and geometric error unseparated. This paper reports a permeability campaign in w...

Two C3/C4 vegetative boundaries and an expanding/contracting Chihuahuan Desert during the past 4000 yr at the Cañada Alamosa Archaeological Project Area, New Mexico

Carbon isotopic measurement (δ13C) as an indicator of C3 or C4 vegetation preserved in soil organic matter and pedogenic carbonate is an important tool for reconstructing paleoclimate. However, while δ13C values of C4 plants (−14‰) generally indicate warm-season grass, δ13C value...

Hydrodynamic Features of Two-Phase Oil–Gas Flow in Pipelines

The results of the experiments on the transport process of fluid flow through a pipeline under temperature gradient conditions between the internal and external environments, and on continuous gas generation at the contact boundary of the transported media, are presented in this...
