The perspective of detectability of Galactic dark matter subhaloes on the Fermi satellite is investigated in this work. Under the assumptions that dark matter annihilation accounts for the “GeV excess” of the Galactic diffuse γrays discovered by EGRET and the γ-ray flux is dominated by the contribution from subhaloes of dark matter, we calculate the expected number of dark matter subhaloes that...

BACKGROUND Different imaging systems (e.g. electrical, magnetic, and ultrasound) rely on a wide variety of physical properties, and the datasets obtained from such systems provide only partial information about the unknown true state. One approach is to choose complementary imaging systems, and to combine the information to achieve a better representation. METHODS This paper discusses the com...

The use of optical dielectrophoresis (ODEP) to manipulate microparticles and biological cells has become increasingly popular due to its tremendous flexibility in providing reconfigurable electrode patterns and flow channels. ODEP enables the parallel and free manipulation of small particles on a photoconductive surface on which light is projected, thus eliminating the need for complex electrod...

Multidimensional tomographic datasets contain physical properties defined over four-dimensional (e.g. spatial-temporal, spatial-spectral), five-dimensional (e.g. spatial-temporal-spectral) or even higher-dimensional domains. Multimodal tomographic datasets contain physical properties obtained with different imaging modalities. In medicine, four-dimensional data are widely used, five-dimensional...

This paper contributes to characterizing the probability density of the price returns in some European day-ahead electricity markets (NordPool, APX, Powernext) by fitting some flexible and general families of distributions, such as the α-stable, Normal Inverse Gaussian (NIG), Exponential Power (EP), and Asymmetric Exponential Power (AEP), and comparing their goodness of fit. The α-stable and th...

In this paper the long time asymptotic behavior of solutions of Maxwell's equations with electric conductivity in an exterior domain with mixed boundary conditions is investigated. It is shown that the solution behaves asymptotically like a free space solution provided it obeys a suitable local decay-property. As a consequence the completeness of the wave-operators is obtained under very genera...

We show that a triaxial atomic force microscopy probe creates a noncontact trap for a single particle in a fluid via negative dielectrophoresis. A zero in the electric field profile traps the particle above the probe surface, avoiding adhesion, and the repulsive region surrounding the zero pushes other particles away, preventing clustering. Triaxial probes are promising for three-dimensional as...

We modify the time-dependent electric potential of the Paul trap from a sinusoidal waveform to a square waveform. Exact quantum motion and Berry’s phase of an electron in the modified Paul trap are found in an analytically closed form. We consider a scheme to detect the Berry’s phase by a BohmAharonov type interference experiment, and point out a critical property which renders it practicable. ...

Telling about the yet another tantalizing property of CNTs that his research has revealed, Basarn says: 'It has been assumed that for carbon nanotubes, the electrical heating process would be governed by Joules law, where resistance in a circuit converts electric energy into heat. We are the first to show mathematically, from a quantum mechanics point of view, that carbon nanotubes do not follo...

Dirac showed that the existence of one magnetic pole in the universe could offer an explanation of the discrete nature of the electric charge. This appealing property has motivated a large experimental effort thus far negative. We describe a scenario in which Dirac monopoles exist but are difficult to detect in isolation. We propose ways of looking to their signatures. Pacs: 14.80.Hv, 98.70.-f,...
