Plant responses to rising vapor pressure deficit.

open access: yesNew 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 ...

Hidden fluid mechanics: Learning velocity and pressure fields from flow visualizations

open access: yesScience, 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 ...

Price pressures [PDF]

open access: yesJournal 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

Under pressure [PDF]

open access: yesEuropean Journal of Pediatrics, 2012
Physical urticaria is a rare but challenging subset of chronic urticaria. Wheals of pressure urticaria are typically delayed in appearance. A pressure test can easily be done to confirm the diagnosis.

The near-room-temperature upsurge of electrical resistivity in Lu-H-N is not superconductivity, but a metal-to-poor-conductor transition

open access: yesMatter and Radiation at Extremes, 2023
The recent report of superconductivity in nitrogen-doped lutetium hydride (Lu-H-N) at 294 K and 1 GPa brought hope for long-sought-after ambient-condition superconductors.

Stamina of a non-gasketed flange joint under combined internal pressure and axial loading [PDF]

open access: yes, 2008
The performance of a bolted flange joint is characterized mainly by its 'strength' and 'sealing capability'. A number of numerical and experimental studies have been conducted to study these characteristics under internal pressure loading conditions ...

Some Magnetic Properties and Magnetocaloric Effects in the High-Temperature Antiferromagnet YbCoC2

open access: yesMagnetochemistry, 2023
The YbCoC2 compound, which crystallizes in a base-centered orthorhombic unit cell in the Amm2 space group CeNiC2 structure, is unique among Yb-based compounds due to the highest magnetic ordering temperature of TN=27 K.

Radiation Pressure Quantization [PDF]

open access: yes, 2018
Kepler's observation of comets tails initiated the research on the radiation pressure of celestial objects and 250 years later they found new incarnation after the Maxwell's equations were formulated to describe a plethora of light-matter coupling ...
