Some Ultraviolet Photomicrographs of B. Subtilis

1. Type-specific antipneumococcus immunity has been induced in rabbits by immunization with antigen prepared by combining a specific derivative of the capsular polysaccharide of Type III Pneumococcus with globulin from horse serum. 2. Rabbits immunized with this antigen acquire active immunity against infection with virulent Type III pneumococci. 3. The sera of the immune rabbits contain type-s...

Rulings of Legendrian knots as spanning surfaces

Each ruling of a Legendrian link can be naturally treated as a surface. For knots, the ruling is 2–graded if and only if the surface is orientable. For 2–graded rulings of homogeneous (in particular, alternating) knots, we prove that the genus of this surface is at most the genus of the knot. While this is not true in general, we do prove that the canonical genus (a.k.a. diagram genus) of any k...

Invariant representation for rectilinear rulings

Ruling gap ratios are an affine-invariant characterization of parallel ruling configurations in scanned documents. This report quantifies the advantage of simultaneous extraction of horizontal and vertical rulings. It demonstrates that every ruling gap ratio can be derived from a minimal set of basis ratios. The effect on the basis ratios of noise on the radial coordinates of individual rulings...

ADE-bundle over rational surfaces, configuration of lines and rulings

To each del Pezzo surface Xn (resp. ruled surface, ruled surface with a section), we describe a natural Lie algebra bundle of type En (resp. Dn−1, An−2) over it . Using lines and rulings on any such surface, we describe various representation bundles corresponding to fundamental representations of the corresponding Lie algebra. When we specify a geometric structure on the surface to reduce the ...

Information Brokerage Via Location-Free Double Rulings

The in-network aggregation and processing of information is what sets a sensor network apart from a pure data acquisition device. One way to model the exchange of information between the network nodes is to distinguish between nodes that are producers of information, i.e., those that have collected data, detected events, etc., and nodes that are consumers of information, i.e., nodes that seek d...
