Influences of Horizontal Initial Stress and Slope Angle on Stress Distribution in Mountains and Cavern Stability
Damage-Fracture Model Initial Lateral Stress Numerical Simulation Slope Angle Stability of Surrounding Rock
2011/12/16
Inbetween the many factors, which will influence the distribution character of initial stress in a mountain, different angle of mountain slopes and horizontal geostress will have important effects on ...
The unusual vertical mass distribution of NGC 4013 seen through the Spitzer Survey of Stellar Structure in Galaxies (S4G)
Spitzer Survey Stellar Structure Galaxies (S4G)
2011/9/27
NGC 4013 is a nearby Sb edge-on galaxy known for its "prodigious" HI warp and its "giant" tidal stream. Previous work on this unusual object shows that it cannot be fitted satisfactorily by a canonica...
Generalized Extreme Value distribution parameters as dynamical indicators of Stability
Generalized Extreme Value distribution parameters dynamical indicators of Stability Dynamical Systems
2011/9/23
Abstract: We introduce a new dynamical indicator of stability based on the Extreme Value statistics showing that it provides an insight on the local stability properties of dynamical systems. The indi...
Distribution of branch lengths and phylogenetic diversity under homogeneous speciation models
phylogenetic tree birth–death process Yule model branch length
2011/9/23
Abstract: The constant rate birth--death process is a popular null model for speciation and extinction. If one removes extinct and non-sampled lineages, this process induces `reconstructed trees' whic...
Dark Matter distribution in the Milky Way: microlensing and dynamical constraints
Dark Matter distribution Milky Way microlensing dynamical constraints
2011/10/20
We show that current microlensing and dynamical observations of the Galaxy allow to set interesting constraints on the Dark Matter local density and profile slope towards the galactic centre. Assuming...
The metallicity distribution of bulge clump giants in Baade's Window
Galaxy: bulge – Galaxy: formation – Galaxy: abundances – Stars: abundances – Stars: atmosphere
2011/10/20
We seek to constrain the formation of the Galactic bulge by means of analysing the detailed chemical composition of a large sample of red clump stars in Baade's window. We measure [Fe/H] in a sample o...
Emission Measure Distribution and Heating of Two Active Region Cores
Emission Measure Distribution Heating Active Region Cores
2011/10/13
Using data from the Extreme-ultraviolet Imaging Spectrometer aboard Hinode, we have studied the coronal plasma in the core of two active regions. Concentrating on the area between opposite polarity mo...
Explicit Bounds for the Distribution Function of the Sum of Dependent Normally Distributed Random Variables
Explicit Bounds Dependent Normally Distributed Random Variables Distribution Function of the Sum
2011/9/19
Abstract: In this paper an analytic expression is given for the bounds of the distribution function of the sum of dependent normally distributed random variables. Using the theory of copulas and the i...
Lognormal Distribution of Single Molecule Fluorescence Bursts in Micro/Nano-Fluidic Channels
Lognormal Distribution Single Molecule Fluorescence Burst Micro/Nano-Fluidic Channels
2011/8/5
Abstract: The width and shape of photon burst histograms pose significant limitations to the identification of single molecules in micro/nano-fluidic channels, and the nature of these histograms is no...
The Tsallis Distribution and Transverse Momentum Distributions in High-Energy Physics
Tsallis Thermodynamics Consistency Heavy Ions
2011/7/21
The Tsallis distribution has been used recently to fit the transverse momentum distributions of identified particles by the STAR collaboration \cite{Abelev:2006cs} at the Relativistic Heavy Ion Collid...
Spectral distribution method for neutrinoless double-beta decay nuclear transition matrix elements: Binary correlation results
neutrinoless double-beta decay nuclear transition
2011/7/20
Neutrinoless double-beta decay nuclear transition matrix elements are generated by an effective two-body transition operator and it consists of Gamow-Teller like and Fermi like (also tensor) operators...
How universal is the Wigner distribution?
Wigner distribution universal Statistical Mechanics
2011/8/17
Abstract: We consider Gaussian ensembles of m N x N complex matrices. We identify an enhanced symmetry in the system and the resultant closed subsector, which is naturally associated with the radial s...

submeasure distribution function probabilistic metric space triangular norm aggregation function semi-copula lattice
2011/9/13
Abstract: Probabilistic submeasures generalizing the classical (numerical) submeasures are introduced and discussed in connection with some classes of aggregation functions. A special attention is pai...
Global Distribution of Fe K alpha Lines in the Galactic Center Region Observed with the Suzaku Satellite

2011/10/9
We have surveyed spatial profiles of the Fe K$\alpha$ lines in the Galactic center diffuse X-rays (GCDX), including the transient region from the GCDX to the Galactic ridge X-ray emission (GRXE), with...
Evolution and Distribution of Magnetic Fields from AGNs in Galaxy Clusters II. The Effects of Cluster Size and Dynamical State
Galaxy Clusters Effects Cluster Size Dynamical State
2011/10/9
Theory and simulations suggest that magnetic fields from radio jets and lobes powered by their central super massive black holes can be an important source of magnetic fields in the galaxy clusters. T...
