By performing DNase I footprint and band-shift analyses of a 170-base-pair region of the murine thymidine kinase promoter, we identified an inducible DNA binding activity that we named Yi. Yi binding activity was not detected in G0 and G1 extracts, but it was observed as cells crossed the G1/S boundary. Yi proteins bind specifically to a consensus sequence (CCCNCNNNCT) found at three distinct s...

Given a set of n data points (xi, yi, zi) ∈ [0, 1] , two methods are established for constructing two piecewise linear copulas, respectively denoted CA(x, y) and CB(x, y), in such a way that CA(xi, yi) and CB(xi, yi) both yield an approximation of zi for all i. If the data points are (randomly) sampled from an unknown copula C, i.e. zi = C(xi, yi), then CA and CB provide two piecewise linear es...

the effects of chromium methionine supplementation on performance and serummetaboliteswere evaluated in broiler chickens.two experiments were conducted at22 oc, thermoneutral, (tn) and33±2 oc, heat stressed (hs) conditions. two hundred and eighty eight male broiler chicks (ross 308) were allocated to four treatments in a completely randomized design. treatments with 0 (control), 200, 400 or 800...

This study investigates propagation of mode I crack in B70 pre-stressed concrete sleepers by fracture mechanics approach. A new experimental analysis is done for notched B70 pre-stressed concrete sleepers with Replica test and image analysis. A scanning electron microscope test (SEM) and an image analysis are applied for the Replica test in order to determine crack length and crack mouth openin...

Objective(s):The hippocampus has been implicated in pathophysiology of schizophrenia. Prenatal stress is a contributing risk factor for a wide variety of neuropsychiatric diseases including schizophrenia. This study examined long-term effects of prenatal restraint stress on the stereological parameters in the Cornu Ammonis (CA) of adult male rats as an animal model of schizophrenia. Materials ...

This study examines the phonetic properties of lexical stress in English produced by Persian speakers learning English as a foreign language. The four most reliable phonetic correlates of English lexical stress, namely fundamental frequency, duration, intensity, and vowel quality were measured across Persian speakers’ production of the stressed and unstressed syllables of five English disyllabi...

The paper discusses the estimation of a continuous density function of the target random field Xi, i ∈ Z N which is contaminated by measurement errors. In particular, the observed random field Yi, i ∈ Z N is such that Yi = Xi + ǫi, where the random error ǫi is from a known distribution and independent of the target random field. Compared to the existing results, the paper is improved in two dir...

A local linear kernel estimator of the regression function x 7→ g(x) := E[Yi|Xi = x], x ∈ R , of a stationary (d+1)-dimensional spatial process {(Yi,Xi), i ∈ Z } observed over a rectangular domain of the form In := {i = (i1, . . . , iN ) ∈ Z N |1 ≤ ik ≤ nk, k = 1, . . . ,N}, n = (n1, . . . , nN ) ∈ Z N , is proposed and investigated. Under mild regularity assumptions, asymptotic normality of th...

A point Pi = (Xi' Yi) in the x-y plane is maximal if there is no point Pi = (Xl> Yi) such that xi> Xi and Yi > Yi. We present a simple data structure, a dynamic contour search tree, which contains all the points in the plane and maintains an embedded linked list of maximal points so that m maximal points are accessible in O(m) time. Our data structure dynamically maintains the set of points so ...

To examine the effects of water stress and Cenangium ferruginosum (CF) on the fungal endophytic community of needles of Pinus koraiensis (PK), fungal endophytes isolated from the needles of 5-year-old PK seedlings were compared before and after exposure to water stress conditions and artificial inoculation with CF ascospores. Artificial CF inoculation was successfully confirmed using PCR with C...
