Using an invariant of Cuntz, we classify reducible shifts of nite type with two irre-ducible components up to ow equivalence. 0. Introduction Let A be an n n matrix over the non-negative integers Z +. Form a directed graph G A with n vertices and A(i; j) edges from vertex i to vertex j. Let E be the set of all edges of G A endowed with the discrete topology. Then the product space E Z is a comp...

Let D be a division ring and let m,n be integers ≥ 2. Let Mm×n(D) be the space of m × n matrices. In the fundamental theorem of the geometry of rectangular matrices all bijective mappings φ of Mm×n(D) are determined such that both φ and φ−1 preserve adjacency. We show that if a bijective map φ of Mm×n(D) preserves the adjacency then also φ −1 preserves the adjacency. Thus the supposition that φ...

This article presents highlights of the research work done in hyperspectral remote sensing in the Himalayan cryosphere. Hyperspectral radiometric investigations conducted at different field locations of NW Himalaya and cold laboratory are discussed. Spectral signatures were collected for varying snow grain size, contamination, liquid water content, vegetation/soilmixed snow, glacier ice, morain...

We give a necessary and su cient condition for a graphical regu lar representation to be adjacency transitive and provide an in nite family of nite simple undirected vertex transitive graphs such that neither nor c is adjacency transitive

Methods and results Geneva prison (for men and women) has 300 beds and serves as a remand prison and for short and medium term sentences. One fifth of the prisoners are dependent on opiates at entry. For our study we cross checked prison medical records with medicolegal necropsv reports in the Canton of Geneva. During 1982-6, 102 sudden deaths among former prisoners were recorded, of which a la...

Intelligent Design Theory (ID) has been much maligned recently as Neo-Creationist pseudoscience. This paper looks briefly at the common arguments used against ID, including arguments from methodological naturalism (MN), falsifiability, productivity, and religious fundamentalism. Ultimately it goes on to explain why the theory could be beneficial to our society today and suggests a need for a me...
