Pathogenic infection in tasar silkworm, Antheraea mylitta Drury. is common and there is a breed specific response regarding tolerance. Observations reveal the possibility of differential response by haemocytes to microbial infection in different breeds. Hence, the susceptibility of three eco-races of tasar silkworm viz. Daba, Sarihan and Raily to Antheraea mylitta Cytoplasmic Polyhedrosis Virus...

We introduce variants of Barvinok’s algorithm for counting lattice points in polyhedra. The new algorithms are based on irrational signed decomposition in the primal space and the construction of rational generating functions for cones with low index. We give computational results that show that the new algorithms are faster than the existing algorithms by a large factor.

We discuss topics related to lattice points in rational polyhedra, including efficient enumeration of lattice points, “short” generating functions for lattice points in rational polyhedra, relations to classical and higher-dimensional Dedekind sums, complexity of the Presburger arithmetic, efficient computations with rational functions, and others. Although the main slant is algorithmic, struct...

Regular (or Platonic) polyhedra have been studied since antiquity, and many other kinds of polyhedra with various symmetry properties have been investigated since then. These include the traditional Archimedean polyhedra (regular-faced with congruent vertex gures), isohedra (polyhedra with faces all equivalent under symmetries of the polyhedron), isogonal polyhedra (all vertices of which are eq...

The structure of the set of all convex polyhedra foldable from a square is detailed. It is proved that five combinatorially distinct nondegenerate polyhedra, and four different flat polyhedra, are realizable. All the polyhedra are continuously deformable into each other, with the space of polyhedra having the topology of four connected rings.

Definitions of polygons and polyhedra, more general than the one traditionally accepted, allow the construction of "new" uniform polyhedra. Although regular polyhedra, as well as some other classes of polyhedra, have recently been discussed from this point of view, the uniform polyhedra seem not to have been considered till now.

We describe the results of an enumeration of several classes of polyhedra. The enumerated classes include polyhedra with up 13 vertices, simplicial polyhedra with up to 16 vertices, 4-connected polyhedra with up to 15 vertices, non-Hamiltonian polyhedra with up to 15 vertices, bipartite polyhedra with up to 24 vertices, and bipartite trivalent polyhedra with up to 44 vertices. The results of th...
