In this paper we are investigating the long time behaviour of the solution of a mutation competition model of Lotka-Volterra’s type. Our main motivation comes from the analysis of the Lotka-Volterra’s competition system with mutation which simulates the demo-genetic dynamics of diverse virus in their host : dvi(t) dt = vi [

In this paper the solutions to the optimal multiobjective H 2 / H D 0 problem are characterized using Banach space duality theory, and shown to satisfy a flatness or allpass condition. Dual and predual spaces are identified, and equivalent maximizations formulated therein. The duality description leads naturally to a solution based on convex programming.

We present noWorkflow, an open-source tool that systematically and transparently collects provenance from Python scripts, including data about the script execution and how the script evolves over time. During the demo, we will show how noWorkflow collects and manages provenance, as well as how it supports the analysis of computational experiments. We will also encourage attendees to use noWorkf...

A category is a category is a category. The whole point of categorization is to treat unlike things as if they were alike. After all, if we treated each encounter with each object or event as the unique thing it is, we would be unable to generalize, unable to learn, unable to remember, unable to communicate. Ignoring differences underlies all of cognition. But which differences to ignore? And a...

We study, as hypersurfaces in toric varieties, elliptic Calabi–Yau fourfolds for F-theory compactifications dual to E8 × E8 heterotic strings compactified to four dimensions on elliptic Calabi–Yau threefolds with some choice of vector bundle. We describe how to read off the vector bundle data for the heterotic compactification from the toric data of the fourfold. This map allows us to construct...

A novel structure called tapped cascaded adap-tive allpass lter is proposed. It is basically an adaptive nite impulse response (AFIR) lter where the delays are replaced by allpass lters. The system induces a better stability monitoring mechanism than in a generic adaptive inn-nite impulse (AIIR) lter. Two adaptation algorithms are derived. The rst one is for adapting the tap-weights when the al...

We analyze the risk-taking behavior of political candidates who are uncertain about the values voters assign to various policy platforms. We show that the majoritarian and proportional electoral systems lead to different outcomes. The proportional system penalizes risky platforms more than the winner-take-all system. Since candidates choose “safer” platforms, in the proportional system voters f...

We propose a systematic method for the synthesis of arbitrary group delay responses by using allpass structures of coupled optical cavities. Optimum structure parameters design, in terms of filter order and accuracy, are obtained. OCIS codes: 140.4780, 060.4510, 230.1150, 350.4600

Visual agnosia is a disorder of recognition confined to the visual realm, in which a person cannot arrive at the meaning of some or all categories of previously known visual stimuli despite normal or near-normal visual perception and intact alertness, intelligence, and language. This article takes a multidisciplinary approach in discussing this impairment and considers clinical and neurological...

Institute of Statistics Mimeo Series #2543 In this paper we describe a method for statistical modeling of the probability of patch occupancy by a species as a function of patch size and other covariates when patches may be incompletely surveyed. The model is appropriate for study designs is which each patch: is visited once; is surveyed at a set of access sites from which an observer can detect...
