In particular, this means that smaller entries of A lead to random variables with smaller variance. On the other hand, the bound on ∥∥∥A− Â∥∥∥ 2 depends on the maximum variance. Thus, to improve the results, one idea is to keep entries of Aij with probability pij ≤ p, so that all entries in  have roughly the same variance. This will help us to get sparser matrices, while keeping similar qualit...

We survey two basic techniques for showing that the monadic second-order theory of a structure is decidable. In the first approach, one deals with finite fragments of the theory (given for example by the restriction to formulas of a certain quantifier rank) and – depending on the fragment – reduces the model under consideration to a simpler one. In the second approach, one applies a global tran...

background and aims:the most common reason in neonatal mortality rate in the world is low birth weight (lbw). the objective of our study was to determine the prevalence and related factors associated in birth weight in garmsar, iran in 2013. methods: this cross sectional study was carried out on 683 live births which delivered in garmsar in 2013. the required information was collected by examin...

RUTH HALL, Marie Stopes. A biography, London, Deutsch, 1977, pp. 351, illus., £5.95. The fascinating story of Marie Stopes (1880-1958) has been told twice before, but this will rank as the best biography of a powerful and extraordinary woman. Mrs. Hall writes well, and by means of the voluminous material available, together with interviews with survivors who were involved, successfully comes to...

The incidence of infantile hypertrophic pyloric stenosis was measured in the West Midlands Health Region between 1974 and 1980. It increased from 2.1/1000 Caucasian births in 1974 to 3.5/1000 in 1980 and reflects a reported increase in Central Scotland. Several artefacts were excluded--for example, repeat admissions to the same hospital, transfers to other hospitals, and changes in treatment an...

Free-ranging mantled howling monkey (Alouatta palliata Gray) females experienced a regular estrus cycle averaging 16.3 days, demonstrated sexual skin changes, and participated in multiple matings before becoming pregnant. Gestation averaged 186 days. The average interval between births was 22.5 months. Sexual maturity occurred at approximately 36 and 42 months for females and males, respectivel...

In this paper, we present a framework for fitting multivariate Hawkes processes for large-scale problems, both in the number of events in the observed history n and the number of event types d (i.e. dimensions). The proposed Scalable LowRank Hawkes Process (SLRHP) framework introduces a lowrank approximation of the kernel matrix that allows to perform the nonparametric learning of the d trigger...

This paper describes our participation in the Federated Web Search track at TREC 2014. Our main focus is on the resource selection task, where we employ a learning-to-rank approach to combine various (instantiations of) resource ranking models. Further, we show that vertical selection can be run on the output from resource selection, and that it directly benefits from the improvements of thereof.

We introduce a generalization of CM-triviality relative to a fixed invariant collection of partial types, in analogy to the Canonical Base Property defined by Pillay, Ziegler and Chatzidakis which generalizes one-basedness. We show that, under this condition, a stable field is internal to the family, and a group of finite Lascar rank has a normal nilpotent subgroup such that the quotient is alm...

Let A be the coordinate ring of an affine elliptic curve (over an infinite field k) of the form X − {p}, where X is projective and p is a closed point on X. Denote by F the function field of X. We show that the image of H•(GL2(A), Z) in H•(GL2(F ), Z) coincides with the image of H•(GL2(k), Z). As a consequence, we obtain numerous results about the K-theory of A and X. For example, if k is a num...
