An instance of the multiperiod binary knapsack problem (MPBKP) is given by a horizon length T, non-decreasing vector sizes $$(c_1, \ldots , c_T)$$ where $$c_t$$ denotes cumulative size for periods $$1,\ldots ,t$$ and list n items. Each item triple (r, q, d) r reward or value item, q its size, d time index (or, deadline). The goal to choose, each deadline t, which items include maximize total re...

The concept of (α, β)-fuzzy Lie algebras over an (α, β)-fuzzy field is introduced. We provide characterizations of an (∈,∈ ∨q)-fuzzy Lie algebra over an (∈,∈ ∨q)-fuzzy field. 2000 MSC: 17B99, 08A72

Traditional spatial queries return, for a given query object q, all database objects that satisfy a given predicate, such as epsilon range and k-nearest neighbors. This paper defines and studies inverse spatial queries, which, given a subset of database objects Q and a query predicate, return all objects which, if used as query objects with the predicate, contain Q in their result. We first sho...

We have prepared a murine monoclonal antibody (MAb) capable of distinguishing between wild-type Venezuelan equine encephalomyelitis (VEE) virus and the TC-83 vaccine derivative. This MAb, 1A2B-10, was derived from immunization with a synthetic peptide corresponding to the first 19 amino acids of the E2 glycoprotein of Trinidad donkey VEE virus. The MAb reacts with prototype viruses from all nat...

Venezuelan equine encephalomyelitis (VEE) epizoodemics were reported at 6-10-year intervals in northern South America beginning in the 1920s. In 1937, epizootic VEE virus was isolated from infected horse brain and shown as distinct from the North American equine encephalomyelitis viruses. Subsequently, epizootic and sylvatic strains were isolated in distinct ecosystems; isolates were characteri...

Venezuelan equine encephalitis (VEE) is a reemerging, mosquito-borne viral disease of the neotropics that is severely debilitating and sometimes fatal to humans. Periodic epidemics mediated by equine amplification have been recognized since the 1920s, but interepidemic disease is rarely recognized. We report here clinical findings and genetic characterization of 42 cases of endemic VEE detected...

The mean time to death of mice infected with Venezuelan equine encephalomyelitis (VEE) virus was increased 2 days by antithymocyte serum (ATS) treatment given 1 day before and 1 day after virus inoculation. Virus assays of blood, brain, and spleen indicated that VEE virus replication was delayed by ATS. Additionally, mice treated with ATS exhibited neurological signs later than untreated mice. ...

Two groups of four dairy cows (Bos taurus) were infected subcutaneously with the epizootic Venezuelan equine encephalomyelitis virus (VEE) strains MF-8 and San Pelayo, respectively. Animals experienced no clinical illness, but all developed significant neutropenia. Virus was recovered once each from the blood of three animals but did not exceed 10(2.2) SMICLD(50) (Suckling mouse intracerebral l...

Column chromatography of selected Venezuelan equine encephalomyelitis (VEE) viruses on calcium phosphate gel offered a simple and reproducible method for examination of biochemical characteristics and relatedness of strains within the VEE complex. Members of antigenic subgroup I demonstrated a series of elution profiles within a narrow range of 0.22 to 0.25 M phosphate buffer. Members of antige...
