Genomic sequences located at the 3' flanking region of the human CD2 gene confer high level tissue-specific, position-independent expression of the gene when introduced in the germ line of mice. In order to further characterize these sequences a range of deletions, from the 3' end were produced and transgenic mice were generated with the human CD2 (hCD2) gene linked to these deleted fragments. ...

This paper presents a region merging process controlled by topological features on regions in 3D images. Betti numbers, a well-known topological invariant, are used as criteria. Classical and incremental algorithms to compute Betti numbers using information represented by the topological map of an image are provided. The region merging algorithm, which merges of any number of connected componen...

Porcine reproductive and respiratory syndrome (PRRS) is recognised as an economically important swine disease worldwide, and is characterised by either reproductive failure in pregnant sows or respiratory tract distress particularly in suckling pigs [7, 32, 37]. The syndrome was first recognised in the United States of America (USA) in the mid 1980’s and was called ‘mystery swine disease’ or ‘b...

We make two remarks about the null-controllability of the heat equation with Dirichlet condition in unbounded domains. Firstly, we give a geometric necessary condition (for interior null-controllability in the Euclidean setting) which implies that one can not go infinitely far away from the control region without tending to the boundary (if any), but also applies when the distance to the contro...

We consider the exact controllability problem on a compact manifold Ω for two coupled wave equations, with a control function acting on one of them only. Action on the second wave equation is obtained through a coupling term. First, when the two waves propagate with the same speed, we introduce the time Tω→O→ω for which all geodesics traveling in Ω go through the control region ω, then through ...

there are many situations for statistical process in which we have both random and vagueinformation. when uncertainty is due to fuzziness of information, fuzzy statistical control charts play animportant role in the monitoring process, because they simultaneously deal with both kinds of uncertainty.dealing with fuzzy characteristics using classical methods may cause the loss of information and ...
