In this work we develop a method for computing mathematically rigorous enclosures of some one dimensional manifolds of heteroclinic orbits for nonlinear maps. Our method exploits a rigorous curve following argument build on high order Taylor approximation of the local stable/unstable manifolds. The curve following argument is a uniform interval Newton method applied on short line segments. The ...

We consider the numerical solution of an acoustic scattering problem by the Plane Wave Discontinuous Galerkin Method (PWDG) in the exterior of a bounded domain in R2. In order to apply the PWDG method, we introduce an artificial boundary to truncate the domain, and we impose a non-local Dirichlet-to-Neumann (DtN) boundary conditions on the artificial curve. To define the method, we introduce ne...

There have been many attempts to create longitudinally-integrated, nation-wide electronic patient record systems ever since information technology has infiltrated the medical profession. This paper compares two recent attempts – a legislative attempt in the Universal Health Identifier (UHID) mandated by the Health Insurance Portability and Accountability Act (HIPAA) and a technical attempt unde...

Piwi-interacting RNAs (piRNAs) silence transposons and maintain genome integrity during germline development. In Drosophila, transposon-rich heterochromatic clusters encode piRNAs either on both genomic strands (dual-strand clusters) or predominantly one genomic strand (uni-strand clusters). Primary piRNAs derived from these clusters are proposed to drive a ping-pong amplification cycle catalyz...

A monodisperse truncation mutant of MxiH, the subunit of the needle from the Shigella flexneri type III secretion system (TTSS), has been overexpressed and purified. Crystals were grown of native and selenomethionine-labelled MxiH(CDelta5) and diffraction data were collected to 1.9 A resolution. The crystals belong to space group C2, with unit-cell parameters a = 183.4, b = 28.1, c = 27.8 A, be...

In this paper, a new predictive coding algorithm for video compression called semi-hexagonal absolute moment block truncation coding (SH-AMBTC) is proposed. It enjoys better objective and subjective qualities over the standard square shaped AMBTC. This technique based on the prediction of the bit-map of the middle frames in a sequence from the bit-map of the end frames (the first and the last f...

In this paper we describe a spiking neural circuit inspired by the pyramidalinterneuron network gamma (PING) circuit modeled by Whittington and colleagues [1]. The spiking network controls a rat animat – a rodent-inspired robot that can autonomously explore and map its environment. We demonstrate how the neural controller directs the rat animat‟s movement towards temporal stimuli of the appropr...

This paper reports on the alignment between mouse and human anatomies, a critical resource for comparative science as diseases in mice are used as mod-els of human disease. The two ontologies under investigation are the NCI Thesaurus (human anatomy) and the Adult Mouse Anatomical Dictionary, each comprising about 2500 anatomical concepts. This study compares two approaches to aligning ontologie...
