current study aimed at determining the most reliable drought tolerant criteria for identification of sugar beet genotypes. a split plot design based on randomized complete block design with three replications was applied at motahari research station, karaj, iran in 2012. two irrigation treatments including normal irrigation after 80-90 mm and irrigation after 270 mm evaporation (stress conditio...

Abstract In this paper, we discuss two types of dimensional adjectives in Nuosu Yi (Tibeto-Burman), which refer to as Positive (PAs) and Equative Adjectives (EAs). We show that PAs EAs are subject different distributions gradation structures: only admissible structures can be associated with measure phrases, include differential comparatives (e.g., Ayi is 2 cm taller than Aguo.) degree question...
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...
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 ...
1. Data The data consist of observations on a bivariate random sample (X1, Y1), · · · , (Xn′ , Yn′), where there are n′ pairs of observations. There should be some natural basis for pairing the observations; otherwise the X’s and Y ’s are independent, and the more powerful MannWhitney test is more appropriate. Within each pair (Xi, Yi) a comparison is made, and the pair is classified as “plus” ...
We prove a fractional version of the Erdős–Szekeres theorem: for any k there is a constant ck > 0 such that any sufficiently large finite set X ⊂ R2 contains k subsets Y1, . . . ,Yk , each of size ≥ ck |X |, such that every set {y1, . . . , yk} with yi ∈ Yi is in convex position. The main tool is a lemma stating that any finite set X ⊂ Rd contains “large” subsets Y1, . . . ,Yk such that all set...
We study the error detection problem in q-ary asymmetric channels wherein every input symbol xi is mapped to an output symbol yi satisfying yi ≥ xi . A general setting is assumed where the noise vectors are (potentially) restricted in: 1) the amplitude, yi − xi ≤ a, 2) the Hamming weight, ∑n i=1 {yi 6=xi} ≤ h 6 6 , and 3) the total weight, ∑n i=1 (yi − xi) ≤ t. Optimal codes detecting these typ...
Let δi = 1 if the i time Yi is an observed death and δi = 0 if it was a right-censored event: That is, the individual was alive at time Yi, but was last seen at that time. If Ti (1 ≤ i ≤ n) are the true survival or failure times, then Yi = Ti if δi = 1 and Yi < Ti if δi = 0, in which case the true failure time Ti is unknown. We also assume d-dimensional covariate vectors X1, X2, . . . , Xn for ...
