Consider rolling a die with k sides, labeled a1, a2, ..., and ak, respectively. Let P(aj) be the ‘probability’ that a particular side aj appears after rolling the die. Before attempting to calculate P(aj), it is necessary to clarify the meaning of the word ‘probability’. In other words, we must specify what the number P(aj) quantifies. In statistics, the concept of ‘probability’ is formally int...
Using 24 million ψ′ ≡ ψ(2S) decays in CLEO-c, we have searched for higher multipole admixtures in electric-dipole-dominated radiative transitions in charmonia. We find good agreement between our data and theoretical predictions for magnetic quadrupole (M2) amplitudes in the transitions ψ′ → γχc1,c2 and χc1,c2 → γJ/ψ, in striking contrast to some previous measurements. Let b2 and a2 denote the n...
In this paper we study a refinement equation of the form φ(x) = ∑ n∈Z hnφ(2x− n), where {hn} is a finitely supported sequence. Let the symbol of the sequnce m(z) := 1 2 ∑ n hnz n take the form m(z) = ( 2 ) Nzk ′∑k j=0 ajz j where ∑ j aj = 1 and ∑ j(−1)aj 6= 0. Under the assumption (∑ 0≤odd j≤k |aj | )2 + (∑ 0≤even j≤k |aj | )2 < 22N−1 we show that the corresponding φ is in L2. Then the B-spline...
Alternatívy k MILP pre rozvrhovanie dávkových banských procesov Cieľom príspevku je navrhnúť možnosť, nahradenia optimalizačných metód na báze zmiešaného celočíselného programovania použitím približných metód rozhodovania (heuristika) v oblasti plánovania a riadenia banských procesov. Výsledkom tohto počítačom podporaovaného plánovania sú detailné výrobné rozvrhy vytvorené podľa požiadaviek ako...
Adherens-type junctions (AJ) are specialized intercellular contacts, mediated by cadherins and characterized by the association with actin filaments through a vinculin- and catenin-rich submembrane plaque. We describe here two mechanisms which potentiate AJ formation in mesenchymal cells. These include the augmentation of AJ by the co-expression of another adhesion molecule, namely NCAM, and th...
Cranial neural crest cells (CNCCs) delaminate from embryonic neural folds and migrate to pharyngeal arches, which give rise to most mid-facial structures. CNCC dysfunction plays a prominent role in the etiology of orofacial clefts, a frequent birth malformation. Heterozygous mutations in SPECC1L have been identified in patients with atypical and syndromic clefts. Here, we report that in SPECC1L...
An analogue of the notion of uniformly separated sequences, expressed in terms of canonical divisors, is shown to yield a necessary and sufficient condition for interpolation in the Bergman space Ap, 0 < p < ∞. A sequence Γ = {zj} of distinct points in the open unit disk D = {z : |z| < 1} of the complex plane is a classical interpolation sequence if for every bounded sequence {aj}, there is a b...
In [Tal94], Talagrand showed a generalization of the celebrated KKL theorem. In this work, we prove that the converse of this generalization also holds. Namely, for any sequence of numbers 0 < a1, a2, . . . , an ≤ 1 such that ∑n j=1 aj/(1 − log aj) ≥ C for some constant C > 0, it is possible to find a roughly balanced Boolean function f such that Infj [f ] < aj for every 1 ≤ j ≤ n.
In this paper, we show that if two non-constant meromorphic functions f and g satisfy E(aj , k, f) = E(aj , k, g) for j = 1, 2, . . . , 5, where aj are five distinct small functions with respect to f and g, and k is a positive integer or ∞ with k ≥ 14, then f ≡ g. As a special case this also answers the longstanding problem on uniqueness of meromorphic functions concerning small functions.
