Most of the authentication systems today don’t just use traditional systems like password or PIN but also rely on biometrics for a better security. Securing the biometric template is thus becoming a major concern in biometrics based systems. Although it is possible to use different biometric traits in combination (multimodal biometrics) to enhance security, it is computationally expensive and t...

A Graph-Based Method for Template Filling in Information Extraction In event-based Information Extraction systems, a major task is the automated filling from unstructured texts of a template gathering information related to a particular event. Such template filling may be a hard task when the information is scattered throughout the text and mixed with similar pieces of information relative to a...

A simple procedure for isolating yeast DNA suitable for use as a template for PCR amplification is described. SDS treatment alone is sufficient for extraction of chromosomal DNA from yeast cells. Cells of a yeast colony are suspended in a small volume (about 20 microL) of a 0.25% SDS solution, mixed vigorously and centrifuged. The supernatant can be directly used as a template after dilution to...

metal complexes, ml (m=ni, cu, co and zn) of unsymmetrical tetradentate schiff base have been synthesized by the template reaction of the half-units n-(1-hydroxy-2-acetonaphthone)-1-amino-2-phenyleneimine)(hl1) with 2-pyrroleca-rbaldehyde. the complexes have been characterized by elemental analysis, ir, 1h nmr and uv spectroscopy. the crystal structure of the ni(ii) complex has been determine...

Short daily periods of binocular vision, if concordant and continuous, have been shown to outweigh or protect against much longer daily periods of monocular deprivation to allow the development of normal visual acuity in both eyes of kittens. The greater weight placed on binocular visual input could arise because of an inherent bias for binocular input within the visual pathway at all times dur...

In event-based Information Extraction systems, a major task is the automated filling from unstructured texts of a template gathering information related to a particular event. Such template filling may be a hard task when the information is scattered throughout the text and mixed with similar pieces of information relative to a different event. We propose in this paper a twostep approach for te...

Compartmentalization of self-replicating molecules (templates) in protocells is a necessary step towards the evolution of modern cells. However, coexistence between distinct template types inside a protocell can be achieved only if there is a selective pressure favoring protocells with a mixed template composition. Here we study analytically a group selection model for the coexistence between t...
