We consider the problem minx∈{0,1}n{cx : ajx ≤ bj , j = 1, . . . , m}, where the aj are random vectors with unknown distributions. The only information we are given regarding the random vectors aj are their moments, up to order k. We give a robust formulation, as a function of k, for the 0-1 integer linear program under this limited distributional information.

Number of objects in the Cybele population, adjacent and exterior to the asteroid main belt, has recently reached more than 1000 with good enough orbits. This allows its more detailed analysis than previously possible. Searching for collisionally-born clusters in this population we find only one statistically robust case: a family of objects about (87) Sylvia. We use a numerical model simulatin...

We show the existence of surfaces of degree d in È 3 () with approximately 3j+2 6j(j+1) d 3 singularities of type A j , 2 ≤ j ≤ d − 1. The result is based on Chmutov's construction of nodal surfaces. For the proof we use plane trees related to the theory of Dessins d'Enfants. Our examples improve the previously known lower bounds for the maximum number µ A j (d) of A j-singularities on a surfac...

For finite subsets A1, . . . , An of a field, their sumset is given by {a1+ · · ·+an : a1 ∈ A1, . . . , an ∈ An}. In this paper we study various restricted sumsets of A1, . . . , An with restrictions of the following forms: ai − aj 6∈ Sij , or αiai 6= αjaj , or ai + bi 6≡ aj + bj (mod mij). Furthermore, we gain an insight into relations among recent results on this area obtained in quite differ...

Organic electronic devices (OEDs) are prone to oxygen‐ and water‐induced degradation therefore need be encapsulated with barrier materials. In this work, an aerosol jet (AJ)‐printing process is developed coat perhydropolysilazane (PHPS) directly onto OEDs by adapting the print setup systematically optimizing parameters. Furthermore, a novel curing that converts PHPS silica layers combining damp...

Identifying genes involved in the control of adherens junction (AJ) remodeling is essential to understanding epithelial morphogenesis. During follicular epithelium development in Drosophila melanogaster, the main body follicular cells (MBFCs) are displaced toward the oocyte and become columnar. Concomitantly, the stretched cells (StCs) become squamous and flatten around the nurse cells. By moni...

Mucolipidosis type IV (MLIV) is a neurodegenerative lysosomal storage disorder that occurs in an increased frequency in the Ashkenazi Jewish (AJ) population. The frequency of the disease in this population has been established by the testing of 66,749 AJ subjects in the Dor Yeshorim program, a unique premarital population-screening program designed for the Orthodox Jewish community. A carrier r...

Let Q(z, w) = − ∏n k=1[(z − ak)(w̄ − āk) − R]. The main result of the paper states that in the case when the nodes aj are situated at the vertices of a regular n-gon inscribed in the unit circle, the matrix Q(ai, aj) is positive definite if and only if R < ρn, where z = 2ρ 2 n − 1 is the smallest 6= −1 zero of the Jacobi polynomial Pn−2ν,−1 ν (z), ν = [n/2].
