The recently identified erythrocyte binding antigen-140 (EBA-140) is a member of the Plasmodium falciparum DBL family of erythrocyte binding proteins, which are considered as prospective candidates for malaria vaccine development. The EBA-140 ligand is a paralogue of the well-characterized P. falciparum EBA-175 antigen. They share homology of domain structure, including Region II, which consist...

An important aspect of speech perception is the ability to group or select formants using cues in the acoustic source characteristics--for example, fundamental frequency (F0) differences between formants promote their segregation. This study explored the role of more radical differences in source characteristics. Three-formant (F1+F2+F3) synthetic speech analogues were derived from natural sent...

A synthetic laboratory population of the diamondback moth, Plutella xylostella (L.), was used to test the F2 screen developed for detecting the frequency of rare resistance alleles to Cry1Ac and Cry1C toxins of Bacillus thuringiensis (Bt). Of the 120 single-pair matings set up, 106 produced enough F2 families for screening of Cry1Ac or Cry1C resistance alleles using both transgenic broccoli and...

Abstract The objective of this work was to assess the genetic control tolerance thermoinhibition in lettuce (Lactuca sativa) seeds. Seeds F1, F2, and F2:3 generations derived from cross between cultivars Everglades (tolerant thermoinhibition) Verônica (sensitive were used, besides seeds parents. Seed germination tests conducted a completely randomized design, with four replicates each parent, e...

Denote the free group on 2 letters by F2 and the SL(2,C)-representation variety of F2 by R = Hom(F2, SL(2,C)). The group SL(2,C) acts on R by conjugation. We construct an isomorphism between the coordinate ring C[SL(2,C)] and the ring of matrix coefficients, providing an additive basis of C[R]SL(2,C) in terms of spin networks. Using a graphical calculus, we determine the symmetries and multipli...

an f2 japanese quail population was developed by crossing two strains (wild and white) to map quantitative trait loci (qtl) for performance and carcass traits. a total of 472 f2 birds were reared and slaughtered at 42 days of age. performance and carcass traits were measured on all of the f2 individuals. parental (p0), f1 and f2 individuals were genotyped with 3 microsatellites from quail chrom...

Abstract. In this work, Neural-Network-based single-station hourly daily foF2 and M(3000)F2 modelling of 15 European ionospheric stations is investigated. The data used are neural networks and hourly daily values from the period 1964– 1988 for training the neural networks and from the period 1989–1994 for checking the prediction accuracy. Two types of models are presented for the F2-layer criti...

Background Oxidative stress is increasingly important in health research. Therefore, it is necessary to understand which factors determine basal oxidative stress. This study examines the associations of various determinants with markers of oxidative DNA and lipid damage: 8-hydroxy-2’-deoxyguanosine (8-OHdG) and F2-isoprostanes. Methods Data are from the Netherlands Study of Depression and Anxie...

Assume that G = (V, E) is an undirected graph with vertex set V and edge set E. The ball Br(v) denotes the vertices within graphical distance r from v. A subset C ⊆ V is called an (r,≤ l)-locating-dominating code of type B if the sets Ir(F ) = ⋃ v∈F (Br(v)∩C) are distinct for all subsets F ⊆ V \C with at most l vertices. A subset C ⊆ V is an (r,≤ l)-locatingdominating code of type A if sets Ir(...
