Bulge properties and dark matter content of early-type barred galaxies

, 2007
The dynamics of a barred galaxy depends on the pattern speed of its bar. The only direct method for measuring the pattern speed of a bar is the Tremaine-Weinberg technique.

A global descriptor of spatial pattern interaction in the galaxy distribution

, 1998
We present the function J as a morphological descriptor for point patterns formed by the distribution of galaxies in the Universe. This function was recently introduced in the field of spatial statistics, and is based on the nearest neighbor distribution

Stochastic modeling of a serial killer

, 2014
We analyze the time pattern of the activity of a serial killer, who during twelve years had murdered 53 people. The plot of the cumulative number of murders as a function of time is of "Devil's staircase" type.

Understanding Balanophyllia regia Distribution in the Canary Islands: Effects of Environmental Factors and Methodologies for Future Monitoring

Diversity
The future of marine ecosystems is at risk due to climate change and other human impacts. Specifically, due to ocean warming, some tropical species are expanding their populations while populations of temperate species are in regression, making the ...

The timing of the formation and usage of replicase clusters in S-phase nuclei of human diploid fibroblasts [PDF]

, 1991
The sites of nascent DNA synthesis were compared with the distribution of the proliferating cell nuclear antigen (PCNA) in S-phase nuclei of human diploid fibroblasts (HDF) by two in vitro techniques.

Beyond the Small-Angle Approximation For MBR Anisotropy from Seeds

, 1994
In this paper we give a general expression for the energy shift of massless particles travelling through the gravitational field of an arbitrary matter distribution as calculated in the weak field limit in an asymptotically flat space-time.

Distributed storage pattern

Annales Universitatis Scientiarum Budapestinensis de Rolando Eötvös Nominatae. Sectio computatorica
In this paper, the principles of a new distributed storage pattern are specified. By this architecture design we provide the system implementing this pattern with new distributed storage features. The pattern specification, implementation and extension possibilities are introduced.
