Waveforms for Gravitational Radiation from Cosmic String Loops [PDF]
, 2000 We obtain general formulae for the plus- and cross- polarized waveforms of gravitational radiation emitted by a cosmic string loop in transverse, traceless (synchronous, harmonic) gauge.

The topological entropy of iterated piecewise affine maps is uncomputable [PDF]
Discrete Mathematics & Theoretical Computer Science, 2001 We show that it is impossible to compute (or even to approximate) the topological entropy of a continuous piecewise affine function in dimension four. The same result holds for saturated linear functions in unbounded dimension.

Piecewise hazard model for under-five child mortality
BLDE University Journal of Health Sciences, 2020 OBJECTIVE: The application of piecewise hazard model in mortality data becomes more useful over classical survival methods. This method is used to find the number of location of cut points and estimate the hazard model.

Piecewise polynomial representations of genomic tracks. [PDF]
PLoS ONE, 2012 Genomic data from micro-array and sequencing projects consist of associations of measured values to chromosomal coordinates. These associations can be thought of as functions in one dimension and can thus be stored, analyzed, and interpreted as piecewise-

Journal of Advanced Research, 2023 Introduction: Recently, a new family of fractional derivatives called the piecewise fractional derivatives has been introduced, arguing that for some problems, each of the classical fractional derivatives may not be able to provide an accurate statement ...

Advances in Applied Mathematics, 1990 AbstractThis paper contains a thorough study of piecewise algebraic sets and functions. They are built up using finitely many parts, each of which is defined by finitely many algebraic equations or inequalities. They occur naturally in many concrete situations which are demonstrated by applications in linear algebra, complexity theory, and meromorphic ...

On shuffle products, acyclic automata and piecewise-testable languages
, 2019 We show that the shuffle $L \unicode{x29E2} F$ of a piecewise-testable language $L$ and a finite language $F$ is piecewise-testable. The proof relies on a classic but little-used automata-theoretic characterization of piecewise-testable languages.

A numerical study of dengue internal transmission model with fractional piecewise derivative
Results in Physics, 2022 The goal of this paper is to study the dynamics of the dengue internal transmission model using a novel piecewise derivative approach in the sense of singular and non-singular kernels.

Ergodic Theory and Dynamical SystemsAbstractWe study piecewise injective, but not necessarily globally injective, contracting maps on a compact subset of ${\mathbb R}^d$ . We prove that, generically, the attractor and the set of discontinuities of such a map are disjoint, and hence the attractor consists of periodic orbits. In addition, we prove that piecewise injective contractions are
