Effect of Landscape Structure on Species Diversity. [PDF]

PLoS ONE, 2013
The effects of habitat fragmentation and their implications for biodiversity is a central issue in conservation biology which still lacks an overall comprehension.

The COINS Sample - VLBA Identifications of Compact Symmetric Objects [PDF]

, 1999
We present results of multifrequency polarimetric VLBA observations of 34 compact radio sources. The observations are part of a large survey undertaken to identify CSOs Observed in the Northern Sky (COINS).

High deuteron and neutron yields from the interaction of a petawatt laser with a cryogenic deuterium jet

Frontiers in Physics, 2023
A compact high-flux, short-pulse neutron source would have applications from nuclear astrophysics to cancer therapy. Laser-driven neutron sources can achieve fluxes much higher than spallation and reactor neutron sources by reducing the volume and time ...

MaxEnt, second variation, and generalized statistics

, 2015
There are two kinds of Tsallis-probability distributions: heavy tail ones and compact support distributions. We show here, appealing to functional analysis' tools, that for lower bound Hamiltonians only the first type guarantees a maximum for Tsallis ...

Asymptotic Behaviours for an Index Whittaker Transform over ${\mathcal{E}}^{\prime }\left({\mathbb{R}}_{+}\right)$

Mathematics
The objective of this research is to obtain the asymptotic behaviour of compactly supported distributions and generalized functions for a variant of the index Whittaker transform.

Optimizing Scan Homogeneity for Building Full-3D Lidars based on Rotating a Multi-Beam Velodyne Rangefinder [PDF]

, 2018
Multi-beam lidar (MBL) scanners are compact, light, and accessible 3D sensors with high data rates, but they offer limited vertical resolution and field of view (FOV). Some recent robotics research has profited from the addition of a degree-of-freedom

Large deviation estimates involving deformed exponential functions

, 2015
We study large deviation properties of probability distributions with either a compact support or a fat tail by comparing them with q-deformed exponential distributions.

Explicit Construction of the Brownian Self-Transport Operator [PDF]

, 2002
Applying the technique of characteristic functions developped for one-dimensional regular surfaces (curves) with compact support, we obtain the distribution of hitting probabilities for a wide class of finite membranes on square lattice.

Note on Boehmians for Class of Optical Fresnel Wavelet Transforms

Journal of Function Spaces and Applications, 2012
We extend the Fresnel-wavelet transform to the context of generalized functions, namely, Boehmians. At first, we study the Fresnel-wavelet transform in the sense of distributions of compact support.

Boundary Kernels for Distribution Function Estimation

Revstat Statistical Journal, 2013
Boundary effects for kernel estimators of curves with compact supports are well known in regression and density estimation frameworks. In this paper we address the use of boundary kernels for distribution function estimation.
