Kahler-currents 扩展 解析奇点
2023/4/14
In this lecture I will talk about Collins-Tosatti's proof on the extension of Kahler currents with analytic singularities.
Record-high Arctic freshwater affecting marine environment and Atlantic Ocean currents（图）
Record-high Arctic freshwater marine environment Atlantic Ocean currents
2021/3/19
Freshwater is accumulating in the Arctic Ocean. The Beaufort Sea, which is the largest Arctic Ocean freshwater reservoir, has increased its freshwater content by 40% over the past two decades. How and...

2015/10/16
The currents induced inside cells by external electric fields in the frequency range 50–60 Hz are studied analytically by accounting for thin cell membranes with transverse conductivity that is small ...
The spectrum of thermally stimulated currents in rock samples from KTB drilling:preliminary results
thermally stimulated depolarization currents (TSDC) KTB drilling rocks relation parameters
2015/9/28
The technique of thermally stimulated depolarization currents (TSDC) was applied to fine grained amphibolite rock samples extracted from KTB drilling. Each sample was cooled down to liquid nitrogen te...
Pressure Stimulated Currents (PSC)in marble samples
Pressure Stimulated Currents (PSC)-Piezo Stimulated Current rocks marble-electricprecursors
2015/9/14
The electrical behaviour of marble samples from Penteli Mountain was studied while they were subjected to uniaxial stress. The application of consecutive impulsive variations of uniaxial stress to thi...

Mapping Surface Currents in Monterey Bay With CODAR-Type HF Radar
Mapping Surface Currents Monterey Bay CODAR-Type HF Radar
2015/8/10
High-frequency (HF) radar measurements have been employed around Monterey Bay, CA, to measure ocean surface currents since February 1992. The first array consisted of two older-generation CODAR instru...
The Coastal Jet:Observations of Surface Currents Over the Oregon Continental Shelf From HF Radar
Coastal Jet Surface Currents Oregon Continental Shelf HF Radar

Internal Wave-Driven Surface Currents HF Radar
2015/8/10
Surface current observations from high-frequency (HF) radar have revealed that not only are the low-frequency and tidal currents resolved by the measurement, higher-frequency motions are also containe...
Two important aspects of tidal currents are (1) their temporal coherence and (2) their constancy (over centuries). The first rigorous evaluation of an Ocean Surface Current Radar (OSCR) system exploit...
