Analysis of a large-scale weighted network of one-to-one human communication [PDF]

, 2007
We construct a connected network of 3.9 million nodes from mobile phone call records, which can be regarded as a proxy for the underlying human communication network at the societal level.

On the average uncertainty for systems with nonlinear coupling [PDF]

, 2016
The increased uncertainty and complexity of nonlinear systems have motivated investigators to consider generalized approaches to defining an entropy function.

Two weighted models for skewed data [PDF]

Journal of Mahani Mathematical Research
The skewed and weighted distributions may be considered as nice alternatives to fit a real data set in practical situations in which the well-known distributions are not suitable.

Two Types of Size-Biased Samples When Modeling Extreme Phenomena

Stats
The present research deals with two possible sources of bias that arise naturally from the selection procedure when modeling extreme phenomena. More specifically, the first type of bias arises when an r-size-biased sample from a set of maximum values is ...

The Weighted GMD Model for multiplicity distributions

EPJ Web of Conferences, 2016
A new distribution, the Weighted GMD (WGMD) is obtained from the Generalised Multiplicity Distribution (GMD), describing charged-particle multiplicity distributions as the hadronisation products of quark and gluon branching with fluctuations in the ...

An intermediate distribution between Gaussian and Cauchy distributions

, 2012
In this paper, we construct an intermediate distribution linking the Gaussian and the Cauchy distribution. We provide the probability density function and the corresponding characteristic function of the intermediate distribution.

Approximations of countably-infinite linear programs over bounded measure spaces [PDF]

, 2019
We study a class of countably-infinite-dimensional linear programs (CILPs) whose feasible sets are bounded subsets of appropriately defined weighted spaces of measures.

Observable Weight Distributions and Children's Individual Weight Assessment [PDF]

Obesity, 2010
Social networks theory suggests obesity is “contagious” within peer groups in that known friends highly influence weight. On the other hand, an alternative model suggests that observable weight distributions affect perception of one's own obesity level.

Quark Wigner Distributions and Orbital Angular Momentum [PDF]

, 2011
We study the Wigner functions of the nucleon which provide multidimensional images of the quark distributions in phase space. These functions can be obtained through a Fourier transform in the transverse space of the generalized transverse-momentum ...
