The article describes and compares two OFDM based communications schemes for reducing the effects of combination Narrowband Interference (NBI) Impulsive Noise (IN), which are noise types typical in Power Line Communication (PLC). Modified BPSK-OFDM (called MBPSK, brevity) QFSK-OFDM QFSK, brevity), non-conventional schemes. We give a description schemes, showing how they derived also show their ...

A $Gamma$-so-ring is a structure possessing a natural partial ordering, an infinitary partial addition and a ternary multiplication, subject to a set of axioms. The partial functions under disjoint-domain sums and functional composition is a $Gamma$-so-ring. In this paper we introduce the notions of subdirect product and $(phi,rho)$-product of $Gamma$-so-rings and study $(phi,rho)$-represen...

Starting from the classical r-matrix of the non-standard (or Jordanian) quantum deformation of the sl(2,R) algebra, new triangular quantum deformations for the real Lie algebras so(2, 2), so(3, 1) and iso(2, 1) are simultaneously constructed by using a graded contraction scheme; these are realized as deformations of conformal algebras of (1 + 1)-dimensional spacetimes. Timetype and space-type q...

We present a 1-parameter family of finite action solutions to the S0(2, 1) Hitchin’s equations and explore some of its basic properties. For a fixed value of the parameter, the solution is smooth. We conclude by showing a multi-particle generalization of our basic solutions.

OBJECTIVE To evaluate intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) and dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) sequences for quantitative characterization of anal fistula activity. METHODS This retrospective study was approved by the institutional review board. One hundred and two patients underwent MRI for clinical suspicion of anal fistula. F...

Abstract In the Addenda to Naming and Necessity (1980), Kripke famously argues that it is false there could have been unicorns, or more properly, “no counterfactual situation properly describable as one in which would unicorns.” He adds he holds similarly ‘one cannot say of any possible person Sherlock Holmes, had existed.” notes “cryptic brevity” these remarks refers a forthcoming work for ela...

This article proposes offline language-free writer identification based on speeded-up robust features (SURF), goes through training, enrollment, and identification stages. In all stages, an isotropic Box filter is first used to segment the handwritten text image into word regions (WRs). Then, the SURF descriptors (SUDs) of word region and the corresponding scales and orientations (SOs) are extr...
