On the cascade mechanism of short surface wave modulation
cascade mechanism short surface wave modulation
2009/11/12
Modulation of short surface ripples by long surface or internal waves by a cascade mechanism is considered. At the first stage, the orbital velocity of the long wave (LW) adiabatically modulates an in...
Evidence for surface organic matter modulation of air-sea CO2 gas exchange
Evidence surface organic matter modulation air-sea CO2 gas exchange
2010/1/20
Air-sea CO2 exchange depends on the air-sea CO2 gradient and the gas transfer velocity (k), computed as a function of wind speed. Large discrepancies among relationships predicting k from wind suggest...
Cygnus x-3：orbital modulation in x-rays and radio。
Laboratory Measurements of Stress Modulation by Wave Groups
wave groups wind-wave generation stress modulation
2009/6/10
The direct action of the wind on waves corresponds to a transfer of momentum (or stress) between air and water. However, the distribution of stress contributions with wavenumber remains an open questi...
Laser Beams with Spatio-Temporal Phase Modulation
Coherence control Partially coherent light Speckle smoothing
2009/6/8
This paper reviews a method of the irradiance profile smoothing on the high-power laser system. In the multi-beam laser irradiation geometry, the coherence control of laser beam is necessary to reduce...
Solar modulation during the Holocene
Solar modulation Holocene cosmogenic radionuclides neutron monitor
2009/5/27
We built a composite of three reconstructions of the solar modulation function over the Holocene. The reconstructions until 1950 are based on data from cosmogenic radionuclides and the present time (1...
Long-term Modulation of Cosmic Ray Intensity in relation to Sunspot Numbers and Tilt Angle
Cosmic ray intensity sunspot numbers tilt angle
2009/5/7
Adetailed correlative analysis between sunspot numbers (SSN) and tilt angle (TA) with cosmic ray intensity (CRI) in the neutron monitor energy range has been performed for the solar cycles 21, 22 and ...
Effect of non-abrupt doping and interfacial profiles on the carrier sheet density in one-side modulation-doped GaN/AlGaN quantum wells
non-abrupt doping interfacial profiles carrier sheet density quantum wells
2010/7/5
The results of an accurate theoretical study on the effects of non-abrupt doping and interfacial profiles on the electron sheet density in one-side modulation-doped wurtzite GaN/AlGaN single quantum w...

Groundwater recharge and capillary rise in a clayey catchment: modulation by topography and the Arctic Oscillation
catchment modelling MIKE SHE capillary rise
2009/3/11
The signature left by capillary rise in the water balance is investigated for a 16 km2 clayey till catchment in Denmark. Integrated modelling for 1981–99 substantiates a 30% uphill increase in average...
Amplitude and phase modulation of time-energy entangled two-photon states
Amplitude phase modulation time-energy two-photon states
2010/4/9
We experimentally demonstrate amplitude and phase modulation of a time-energy entangled two-photon wave function. The entangled photons are produced by spontaneous parametric down-conversion, spectral...
Modulation of Gulf Stream Surface–Subsurface Frontal Separation by Path Curvature
Gulf Stream surface–subsurface frontal separation ubsurface-front path curvature
2009/1/7
Observations of surface–subsurface frontal separation have inconsistently demonstrated a relationship between surface–subsurface frontal separation and subsurface-front path curvature. An analytical m...
The Control of Fjord Circulation by Fortnightly Modulation of Tidal Mixing Processes
Fjord Circulation Fortnightly Modulation Tidal Mixing Processes
2008/12/19
Tidal processes that control basin–ocean water exchange across a sill, namely, the fortnightly modulation of mixing intensity associated with the spring-neap tidal cycle, are examined. The study proce...
The Seasonal Cycle and Its Modulation in the Eastern Tropical Pacific Ocean
sea surface temperature intertropical convergence zone Comprehensive Ocean-Atmosphere Data Sets
2008/12/3
Data for the period from 1985 to 1993 from TAO moorings along 110°W (5°S–5°N) and 140°W (2°S–9°N) describe the vertical, meridional, and temporal structure of the seasonal cycle of several variables. ...
