Plants exhibit an exceptional adaptability to different environmental conditions. To a large extent, this adaptability depends on their ability to initiate and form new organs throughout their entire postembryonic life. Plant shoot and root systems unceasingly branch and form axillary shoots or lateral roots, respectively. The first event in the formation of a new organ is specification of foun...

MOTIVATION Sequence similarity searches performed with BLAST, SSEARCH and FASTA achieve high sensitivity by using scoring matrices (e.g. BLOSUM62) that target low identity (<33%) alignments. Although such scoring matrices can effectively identify distant homologs, they can also produce local alignments that extend beyond the homologous regions. RESULTS We measured local alignment start/stop b...

The problem of tracking and managing the identities of multiple targets is discussed and applied to the passive radar tracking of aircraft. The targets are assumed to be commercial aircraft switchingmodes during flight, and are thus well modeled by hybrid systems. We propose a computationally efficient algorithm based on joint probabilistic data association for target-measurement correlation. W...

We give a new proof of a polynomial identity involving the minors of a matrix, that originated in the study of integer torsion in a local cohomology module.

A fingerprint authentication system for the privacy protection of the virtual identity is introduced. By extracting minutiae points from one fingerprint, orientation from other fingerprint and reference points from both the fingerprints, a new biometric authentication framework is proposed for identifying an individual. With the help of these three combined features a new virtual identity is ge...

atholic health care finds itself within a rapidly changing landscape. In response, some Catholic hospitals and collaborative health systems are making structural changes. Some systems have decided to forego formal recognition by the local bishop, for example, while a few hospitals and systems have begun to explore for-profit corporate structures. These and other new models-in-the-making may hav...

There is a growing body of research in racial and ethnic studies on the processes of identity construction within minority ethnic populations. This article seeks to build on this work by analysing emerging collective identity formations in an ‘invisible’ minority ethnic group. Based upon focus groups and in-depth interviews with Irish people in Sheffield, the article aims to advance three key a...

We propose that social categorization can encourage particular forms of intergroup cooperation because it differentiates a group in need from a group that can give aid. Moreover, social categorization is most likely to occur when individuals perceive procedural justice (i.e., fair treatment) from authorities in a superordinate group that includes the individuals' subgroup. Two field studies inv...

In this paper we prove the Pohozaev identity for the semilinear Dirichlet problem (−∆)u = f(u) in Ω, u ≡ 0 in R\Ω. Here, s ∈ (0, 1), (−∆) is the fractional Laplacian in R, and Ω is a bounded C domain. To establish the identity we use, among other things, that if u is a bounded solution then u/δ|Ω is C up to the boundary ∂Ω, where δ(x) = dist(x, ∂Ω). In the fractional Pohozaev identity, the func...

Models of contour interpolation have been proposed for illusory contour interpolation but seldom for interpolation of occluded contours. The identity hypothesis (Kellman & Loukides, 1987; Kellman & Shipley, 1991) posits that an early interpolation mechanism is shared by interpolated contours that are ultimately perceived as either illusory or occluded. Here we propose a model of such a unified ...
