Hidden fluid mechanics: Learning velocity and pressure fields from flow visualizations
Science, 2020 Machine-learning fluid flow Quantifying fluid flow is relevant to disciplines ranging from geophysics to medicine. Flow can be experimentally visualized using, for example, smoke or contrast agents, but extracting velocity and pressure fields from this ...

Journal of Financial Economics, 2014 We study price pressures, i.e., deviations from the efficient price due to risk-averse intermediaries supplying liquidity to asynchronously arriving investors. Empirically, New York Stock Exchange intermediary data reveals economically large price pressures, 0.49% on average with a half life of 0.92 days. Theoretically, a simple dynamic inventory model

Phase transition mechanism and bandgap engineering of Sb2S3 at gigapascal pressures
Communications Chemistry, 2021 Antimonite (Sb2S3) has potential applications for solar energy, but how its layered structure changes under pressure is incompletely understood. Here diamond anvil cell experiments supported by first principles calculations offer a structural explanation

Plant responses to rising vapor pressure deficit.
New Phytologist, 2020 Recent decades have been characterized by increasing temperatures worldwide, resulting in an exponential climb in vapor pressure deficit (VPD). VPD has been identified as an increasingly important driver of plant functioning in terrestrial biomes ...

Sub-terahertz feedback interferometry and imaging with emitters in 130 nm BiCMOS technology
Scientific Reports, 2023 In this work, we present the effect of self-mixing in compact terahertz emitters implemented in a 130 nm SiGe BiCMOS technology. The devices are based on a differential Colpitts oscillator topology with optimized emission frequency at the fundamental ...

Journal of Futures Markets, 2018 AbstractThe paper investigates the information content of speculative pressure across futures classes. Long‐short portfolios of futures contracts sorted by speculative pressure capture a significant premium in commodity, currency, and equity markets but not in fixed income markets.
