The pretest availability of 10% sucrose solution and/or partial blood engorgement in Aedes albopictus Skuse significantly influenced mosquito attack rates and the time of repellent protection in laboratory bioassays. In 46 cm L x 38 cm W x 37 cm H cages used in USDA repellent tests, non-blood-fed and partially blood-fed mosquitoes attempted to bite at similar rates. In small cages (5 cm dia. x ...

1. The E.A. (Euclidean Algorithm) holds for a quadratic field R(2/.m)? when, for any two integers a, ,G in R(~/m.) with /3 + 0, a third integer y in B(~/w) can be so det,ermined that (1) 1 N(a-/3y) / < j N(P) (or \ N(a/fi-y) 1 < 1. The existence of the E .A. is undecided in the following cases; p, q denoting primes : y I. m=p= 13+24n (,n> 1); II. m=p= 1+&L (n> 7); III. m =pq wit#h 23 = q-3 or p...

For V a 2-dimensional p-adic representation of GQp , we denote by B(V ) the admissible unitary representation of GL2(Qp) attached to V under the p-adic local Langlands correspondence of GL2(Qp) initiated by Breuil. In this article, building on the works of Berger-Breuil and Colmez, we determine the locally analytic vectors B(V )an of B(V ) when V is irreducible, crystabelian and Frobenius semi-...

Then qk(t) = log det (I +Kk)− log det (I +Kk−1) is a solution to the system of equations. If ρ is supported in the set of nth roots of unity then the solution is n-periodic in that qk+n = qk for all k. The main interest is in the limit t→ 0+, while the t→ ∞ asymptotics are straightforward. The asymptotics for the qk are known once those for the determinants are, and since ρ is arbitrary there i...

Pin structures on vector bundles are the natural generalization of Spin structures to the case of nonoriented bundles. Spin(n) is the central Z/2Z extension (or double cover) of SO(n) and Pin−(n) and Pin(n) are two different central extensions of O(n), although they are topologically the same. The obstruction to putting a Spin structure on a bundle ξ (= R → E → B) is w2(ξ) H(B;Z/2Z); for Pin it...

Eleven recessive mutant loci define the class of cop / det / fus mutants of Arabidopsis. The cop / det / fus mutants mimic the phenotype of light-grown seedlings when grown in the dark. At least four cop / det / fus mutants carry mutations in subunits of the COP9 signalosome, a multiprotein complex paralogous to the 'lid' subcomplex of the 26S proteasome. COP1, another COP/DET/FUS protein, is i...

For any collection of sets of reals C, let C-DET be the statement that all sets of reals in C axe determined. In this paper we study questions of the form: For given C Q C, when is C'-DET equivalent, equiconsistent or strictly stronger in consistency strength than C-DET (modulo ZFC)? We focus especially on classes C contained in the projective sets.

Laboratory and field efficacy trials comparing deet (N,N-diethyl-3-methylbenzamide) and SS220 [(IS, 2'S)-2-methylpiperindinyl-3-cyclohexen-1-carboxamide] against mosquitoes in Queensland, Australia, were conducted. In the laboratory, both compounds provided between 150 and 195 min of protection against Aedes aegypti and between 18 and 80 min of protection against Anopheles farauti. In laborator...

Let Ω ⊂ 2 be a bounded Lipschitz domain and let F : Ω× 2×2 + −→ be a Carathèodory integrand such that F (x, ·) is polyconvex for L2-a.e. x ∈ Ω. Moreover assume that F is bounded from below and satisfies the condition F (x, ξ) ↘ ∞ as det ξ ↘ 0 for L2-a.e. x ∈ Ω. The paper describes the effect of domain topology on the existence and multiplicity of strong local minimizers of the functional [u] := ∫

Let f be an analytic function on the plane and A a square matrix of order n whose eigenvalues are contained in the interior of a circle K centered at the origin. The expression f(A) = fKf(z)(z-A)-dz has been widely used to calculate (or define) the value of f at A. A special case of this formula provides us with a trivial proof of the Cayley-Hamilton theorem. We need only the most elementary no...
