Network coding for non-uniform demands [PDF]

open access: yes, 2005
Non-uniform demand networks are defined as a useful connection model, in between multicasts and general connections. In these networks, each sink demands a certain number of messages, without specifying their identities.

Properties of Water Bound in Hydrogels

open access: yesGels, 2017
In this review, the importance of water in hydrogel (HG) properties and structure is analyzed. A variety of methods such as 1H NMR (nuclear magnetic resonance), DSC (differential scanning calorimetry), XRD (X-ray powder diffraction), dielectric ...

Non-uniformity issues and workarounds in bounded-size sampling

open access: yesThe VLDB Journal, 2013
A variety of schemes have been proposed in the literature to speed up query processing and analytics by incrementally maintaining a bounded-size uniform sample from a dataset in the presence of a sequence of insertion, deletion, and update transactions.

Bounded cohomology and non-uniform perfection of mapping class groups [PDF]

open access: yesInventiones mathematicae, 2001
Using the existence of certain symplectic submanifolds in symplectic 4-manifolds, we prove an estimate from above for the number of singular fibers with separating vanishing cycles in minimal Lefschetz fibrations over surfaces of positive genus. This estimate is then used to deduce that mapping class groups are not uniformly perfect, and that the map ...

On an improved computational solution for the 3D HCIR PDE in finance

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2019
The aim of this work is to tackle the three–dimensional (3D) Heston– Cox–Ingersoll–Ross (HCIR) time–dependent partial differential equation (PDE) computationally by employing a non–uniform discretization and gathering the finite difference (FD) weighting

DP-colorings of uniform hypergraphs and splittings of Boolean hypercube into faces

open access: yes, 2022
We develop a connection between DP-colorings of $k$-uniform hypergraphs of order $n$ and coverings of $n$-dimensional Boolean hypercube by pairs of antipodal $(n-k)$-dimensional faces. Bernshteyn and Kostochka established that the lower bound on edges in

An analytical solution to the multicommodity network flow problem with weighted random routing

open access: yesApplied Network Science, 2021
We derive an analytical expression for the mean load at each node of an arbitrary undirected graph for the non-uniform multicommodity flow problem under weighted random routing. We show the mean load at each node, net of its demand and normalized by its (

Non-Uniform and Non-Random Binding of Nucleoprotein to Influenza A and B Viral RNA

open access: yesViruses, 2018
The genomes of influenza A and B viruses have eight, single-stranded RNA segments that exist in the form of a viral ribonucleoprotein complex in association with nucleoprotein (NP) and an RNA-dependent RNA polymerase complex.

Direct position determination algorithm for non‐circular sources in the presence of mutual coupling and its theoretical performance analysis

open access: yesIET Signal Processing, 2023
This article proposes a direct position determination (DPD) algorithm for non‐circular sources observed by a moving array using the self‐calibration technique in the presence of mutual coupling.
