The cell surfaces of several toxigenic and nontoxigenic environmental and clinical isolates of Vibrio cholerae non-O1 have been examined. The environmental strains, irrespective of toxigenicity, are significantly more resistant to antibiotics and detergents than are V. cholerae O1 strains. The clinical isolates of non-O1 vibrios are as sensitive to a wide variety of chemicals as the O1 vibrios....

In this paper we argue that maximum expected utility is a suitable framework for modeling a broad range of decision problems arising in pattern recognition and related fields. Examples include, among others, gaze planning and other active vision problems, active learning, sensor and actuator placement and coordination, intelligent humancomputer interfaces, and optimal control. Following this re...

Parasitism has been argued as one o1 the major costs o1 breeding sociality in birds. Mowever, there is no clear evidence 1or an increased parasite pressure associated with the evolutionary transition 1rom solitary to colonial breeding. I used the pairwise comparative method to test whether colonial bird species incur in a greater risK o1 in1ection and i1 they must to 1ace with a greater diversi...

where ◦o1,o2,o3 : 〈o2,o3〉×〈o1,o2〉 → 〈o1,o3〉 that satisfies usual conditions (associativity and the existence of the identities). This approach is closer to the way in which categories are presented in homological algebra (e.g. [1], pp.58-59). We do not assume that 〈o1,o2〉’s are mutually disjoint. If f is simultaneously a morphism from o1 to o2 and o1 to o2 (o1 6= o1) than different compositions...

The articles [6], [1], [4], [5], [2], and [3] provide the notation and terminology for this paper. Let O1 be an ordered affine space. Then Λ(O1) is an affine space. Let O1 be an ordered affine plane. Then Λ(O1) is an affine plane. We now state several propositions: (1) There exists a real linear space V and there exist vectors u, v of V such that for all real numbers a, b such that a · u + b · ...

Six hybridoma cell lines, each of which produced a monoclonal antibody (MAb) against Vibrio cholerae O1 lipopolysaccharide (LPS), were established. Each MAb was active serologically by both enzyme-linked immunosorbent assay (ELISA) and the slide agglutination test. In the ELISA, each MAb was tested against 7 O1 and 9 non-O1 LPS preparations. Three MAbs reacted with both Inaba and Ogawa serovars...

Vibrio cholerae, the causative agent of major epidemics of diarrheal disease in Bangladesh, South America, Southeastern Asia, and Africa, was isolated from clinical samples and from aquatic environments during and between epidemics over the past 20 years. To determine the evolutionary relationships and molecular diversity of these strains, in order to understand sources, origin, and epidemiolog...

In this paper C denotes a category and o1, o2, o3 denote objects of C. Let C be a non empty category structure with units and let o be an object of C. Observe that 〈o, o〉 is non empty. The following propositions are true: (1) Let v be a morphism from o1 to o2, u be a morphism from o1 to o3, and f be a morphism from o2 to o3. If u = f · v and f −1 · f = id(o2) and 〈o1, o2〉 6= ∅ and 〈o2, o3〉 6= ∅...
