This paper considers estimation of the regression function and its derivatives in nonparametric regression with fractional time series errors. We focus on investigating the properties of a kernel dependent function V (δ) in the asymptotic variance and finding closed form formula of it, where δ is the long-memory parameter. It is shown that V (δ) has a unified form for δ ∈ (−0.5, 0.5)\0 with V (...

BACKGROUND The use of medial rectus pulley posterior fixation sutures to treat esotropia with convergence excess has limited support in the literature. We describe our results using this technique to treat patients with large near-distance disparities. METHODS We retrospectively analyzed records of patients with accommodative or partially accommodative esotropia and convergence excess 13(Δ) o...

We explored δ(15)N compound-specific amino acid isotope data (CSI-AA) in filter-feeding intertidal mussels (Mytilus californianus) as a new approach to construct integrated isoscapes of coastal primary production. We examined spatial δ(15)N gradients in the California Upwelling Ecosystem (CUE), determining bulk δ(15)N values of mussel tissue from 28 sites between Port Orford, Oregon and La Joll...

The decays ¯ B → ¯ KD and ¯ B → ¯ K ¯ D taking into account final state interactions are discussed. These decays are described by four strong phases δ 0 , δ 1 , ˜ δ 0 , ˜ δ 1 (subscript 0 and 1 refer to I = 0 and I = 1 isospin final states), one weak phase γ and four real amplitudes. Isospin constraints are taken into account. It is argued that strong interaction dynamics gives δ 1 ≈ ˜ δ 1. The...

For a smooth surface S in P 3 of degree d and for positive integers n, δ, the Severi variety V 0 n,δ (S) is the subvariety of the linear system |O S (n)| which parametrizes curves with δ nodes. We show that for S general, n ≥ d and for all δ with 0 ≤ δ ≤ dim(|O S (n)|), then V 0 n,δ (S) has at least one component which is reduced, of the expected dimension dim(|O S (n)|) − δ. We also construct ...

Let F 2ν δ l q be a 2ν δ l -dimensional vector space over the finite field Fq. In this paperwe assume that Fq is a finite field of odd characteristic, and O2ν δ l, Δ Fq the singular orthogonal groups of degree 2ν δ l over Fq. Let M be any orbit of subspaces under O2ν δ l, Δ Fq . Denote by L the set of subspaces which are intersections of subspaces in M, where we make the convention that the int...

An R-module M is called strongly noncosingular if it has no nonzero Rad-small (cosingular) homomorphic image in the sense of Harada. It is proven that (1) an R-module M is strongly noncosingular if and only if M is coatomic and noncosingular; (2) a right perfect ring R is Artinian hereditary serial if and only if the class of injective modules coincides with the class of (strongly) noncosingula...

Let S and Δ be numerical semigroups. A semigroup is an I(Δ)-semigroup if \ {0} ideal of Δ. We denote by ℐ (Δ) = {S | I(Δ)-semigroup}, we say that extension ∈ (Δ).

Given a double-well potential F , a Z-periodic function H, small and with zero average, and ε > 0, we find a large R, a small δ and a function Hε which is ε-close to H for which the following two problems have solutions: 1. Find a set Eε,R whose boundary is uniformly close to ∂BR and has mean curvature equal to −Hε at any point, 2. Find u = uε,R,δ solving −δ∆u+ F (u) δ + c0 2 Hε = 0, such that ...
