Practical and Fast Quantum Random Number Generation Based on Photon Arrival Time Relative to External Reference
Practical Fast Quantum Random Number Generation Photon Arrival Time Relative External Reference
2016/1/22
We present a practical high-speed quantum random number generator, where the timing of single-photon detection relative to an external time reference is measured as the raw data. The bias of the raw d...
The external magnetic sources over the polar caps - Feasible modelling unrealistic expectations
magnetospheric model plasma cavity Hamilton's principle substorm auroral oval Svalgaard vortex ? aurora luminosity curve electric current electric field plasma drift trapped particles
2015/10/8
No average status can be defined for the sources of the external magnetic field over the polar caps, no index can provide with any such model, the observation of no single quantity or parameter can gi...
Background electromagnetic noise characterization: the role of external and internal Earth sources
Radio noise characterization Ionosphere-magnetosphere Background EM noise Crustal/lithospheric EM sources
2015/8/14
The Earth is surrounded by the ionosphere and magnetosphere that can roughly be seen schematically as two concentric shells. These two composed and inhomogeneous structured shells around the Earth sel...
Existing (Spitzer Space Telescope) and upcoming (Herschel Space Telescope) facilities are deepening our understanding of the role of dust in tracing the energy budget and chemical evolution of galaxie...
New Panoramic View of $^{12}$CO and 1.1 mm Continuum Emission in the Orion A Giant Molecular Cloud. I. Survey Overview and Possible External Triggers of Star Formation
star formation
2014/12/22
We present new, wide, and deep images in the 1.1 mm continuum and the CO ( 1–0) emission toward the northern part of the Orion A Giant Molecular Cloud (Orion-A GMC). The 1.1 mm data were taken with th...

Accurate estimates of soil organic carbon (SOC)
stocks are required to quantify carbon sources and sinks
caused by land use change at national scale.
The CSIRO Mk3L climate system model version 1.0 – Part 2: Response to external forcings
The CSIRO Mk3L climate system model version 1.0 – Part 2 external forcings
2014/12/10
The CSIRO Mk3L climate system model is a coupled general circulation model, designed primarily for millennial-scale climate simulation and palaeoclimate research. Mk3L includes components which descri...
The evolution of globular clusters: Analysis of external effects and determination of progenitor populations
Globular cluster evolution Evolution The Milky Way. Base elliptical galaxies galaxy
2014/12/9
We include external effects in the Fokker-Planck scheme for studying globular cluster evolution. We use this method to study cluster evolution under the combined influence of relaxation, tidal heating...
Using stable nitrogen isotopes to evaluate the relative importance of external and internal nitrogen loadings on phytoplankton production in a shallow eutrophic lake (Lake Mikata, Japan)
a shallow eutrophic lake phytoplankton production
2014/4/2
The seasonal variability of the stable nitrogen isotope (d15N) in phytoplankton and dissolved inorganic
nitrogen (DIN) in the shallow, eutrophic Lake Mikata was examined to assess the relative import...
Singular parabolic p-Laplacian systems under non-smooth external forces. Regularity up to the boundary
Initial-boundary value problems p-Laplacian parabolic singular systems regularity up to the boundary
2012/6/30
We study the regularity of the solutions to initial-boundary value problems for N-systems of the p-Laplacian type, in $n\geq 3$ space variables, with square-integrable external forces in the space-tim...

Efficient method optically-pumped vertical external cavity surface emitting lasers equally excited quantum wells Optics
2012/4/20
Even distribution of carriers allows to maximize optical gain of the Optically-Pumped Vertical External Cavity Surface Emitting Laser. In this paper we show how to distribute the quantum wells and blo...
Diffusion Based Modeling of Human Brain Response to External Stimuli
Diffusion Modeling of Human Brain External Stimuli Analysis of PDEs
2012/4/18
Human brain response is the overall ability of the brain in analyzing internal and external stimuli in the form of transferred energy to the mind/brain phase-space and thus, making the proper decision...
Phase lagging model of brain response to external stimuli - modeling of single action potential
phase lagging model brain response external stimuli action potential single neuron
2012/4/28
In this paper we detail a phase lagging model of brain response to external stimuli. The model is derived using the basic laws of physics like conservation of energy law. This model eliminates the par...
