Let p be a prime number, Fp be a finite field, and let k ∈ Fp. In this paper, we consider the number of rational points on conics Cp,k : x − ky = 1 over Fp. We proved that the order of Cp,k over Fp is p− 1 if k is a quadratic residue mod p and is p+1 if k is not a quadratic residue mod p. Later we derive some results concerning the sums ∑ C [x] p,k(Fp) and ∑ C [y] p,k(Fp), the sum of x− and y−c...

1: Properties of the shuffle product in positive characteristic suggest to consider a p−homogeneous form σ : Fp〈〈X1, . . . ,Xk〉〉 −→ Fp〈〈X1, . . . ,Xk〉〉 on the vector space Fp〈〈X1, . . . ,Xk〉〉 of formal power series in k free noncommuting variables. The form σ preserves rational elements in Fp〈〈X1, . . . ,Xk〉〉, algebraic series of Fp[[X]] and induces a bijection on the affine subspace 1+m of for...

PURPOSE To determine the distribution of the prostaglandin F2 alpha (FP) receptor within the monkey eye. METHODS The expression and localization of the FP receptor was studied by in situ hybridization and immunohistochemistry. Cryosections of the eye were hybridized with a 35S-labeled FP receptor riboprobe, and paraffin sections were immunostained with polyclonal antibodies against an FP rece...

When foreperiods (FPs) of different duration vary on a trial-by-trial basis equiprobably but randomly, the RT is faster as the FP increases (variable FP effect), and becomes slower as the FP on the preceding trial gets longer (sequential effects). It is unclear whether the two effects are due to a common mechanism or to two different ones. Patients with lesions on the right lateral prefrontal c...

Recent increases in family planning (FP) use have been reported among women of reproductive age in union (WRAU) in Senegal. However, trends have not been monitored among harder-to-reach groups (including adolescents, unmarried and rural poor women), key to understanding whether FP progress is equitable. We combined data from six Demographic and Health Surveys conducted in Senegal between 1992/9...

Incubation of a 0.5% suspension of washed normal mouse erythrocytes with ferriprotoporphyrin IX (FP) for 2.5 h at 37 degrees C and pH 7.4 results in sufficient membrane damage to produce hemolysis. A sigmoidal dose-response curve is followed with 50% hemolysis being produced by 4 microM FP. Complete hemolysis is produced by 6 microM FP. The hemolytic process has at least two phases: a lag phase...

A peptide construct (FPtr) was synthesized which mimics the biologically relevant topology of fusion peptide (FP) domains of the trimeric HIV-1 gp41 envelope protein. The FP domains play a critical role in gp41-catalyzed fusion of viral and host cell membranes which is a key step in viral infection. The FPtr construct contains three FP strands chemically bonded at their C-termini through lysine...

For a polynomial f(x) in (Zp∩Q)[x] of degree d ≥ 3 let L(f⊗Fp;T ) be the L function of the exponential sum of f mod p. Let NP(f⊗Fp) denote the Newton polygon of L(f⊗Fp;T ). Let HP(Ad) denote the Hodge polygon of Ad, which is the lower convex hull in R2 of the points (n, n(n+1) 2d ) for 0 ≤ n ≤ d−1. Let Ad be the space of degree-d monic polynomials parameterized by their coefficients. Let GNP(A;...

The ZEBRA protein encoded by the Epstein-Barr virus (EBV) genome activates a switch from the latent to the lytic gene expression programme of the virus. ZEBRA, a member of the basic leucine zipper family of DNA-binding proteins, is a transcriptional activator capable of inducing expression from several virus lytic cycle promoters by binding to activator protein 1 (AP-1)-like sites. The Epstein-...
