In this paper, we give a short survey on discrete geometry on red and blue points in the plane, most of whose results were obtained in the past decade. We consider balanced subdivision problems, geometric graph problems, graph embedding problems, Gallai-type problems and others. 1 Notation and Definitions In this paper, we give a short survey on discrete geometry on red and blue points in the p...

Comparative analysis of development and survivorship of two geographically divergent populations of the Natal fruit fly Ceratitis rosa Karsch designated as Ceratitis rosa R1 and Ceratitis rosa R2 from Kenya and South Africa were studied at seven constant temperatures (10, 15, 20, 25, 30, 33, 35 °C). Temperature range for development and survival of both populations was 15-35 °C. The development...

The cyanamides NCNR2 (R2 = Me2, Ph2, C5H10) react with ZnX2 (X = Cl, Br, I) in a 2 : 1 molar ratio at RT, giving a family of zinc(ii) complexes [ZnX2(NCNR2)2] (R2 = Me2, X = Cl , X = Br , X = I ; R2 = C5H10, X = Cl , X = Br ; X = I ; R2 = Ph2, X = Cl , X = Br , X = I ; 75-92% yields). Complexes and undergo ligand redistribution in wet CH2Cl2 solutions giving the [Zn(NCNPh2)4(H2O)2][Zn2(μ-X)2X4]...

It is shown that for any expansive, integer valued 2×2 matrix, there exists a (multi-)wavelet whose Fourier transform is compactly supported and smooth. A key step is showing that for almost every equivalence class of integrally similar matrices there is a representative A which is strictly expansive in the sense that there is a compact set K which tiles the plane by integer translations and su...

Introduction Subdural haematoma (SDH) is a form of traumatic brain injury that can be classified as acute, subacute or chronic, based upon time from injury. When acute, it is a medical emergency in which surgical decompression is the only option to prevent mortality. Small subdurals and those that are no longer actively bleeding may be left to re-absorb spontaneously and clinical decision-makin...

R2 is an attempt to create an interconnection component that provides reliable packet delivery services at low latency under bursty traac situations and in the presence of certain faults in either the network or processing elements. The R2 design is based on a damped adap-tive routing scheme that avoids livelock, exhibits improved latency under bursty congestion, while performing similar to det...

This paper describes the fourth participation of IR-n system (Alicante University) at CLEF conferences. At present conference, we have modified the similarity measure and the query expansion model. Concerning the similarity measure, we use the normalization based on the number of words for each one of the passages. Finally, we test two different approaches for query expansion: the first one is ...

R2-type measures are commonly used tools for assessing the predictive power of linear regression models; for generalized linear models this measure is based on deviances. For small samples, it is necessary to adjust R2 for the number of covariates. This article shows that some of the adjustments that have been proposed for logistic, Poisson, gamma and inverse Gaussian models, can be expressed i...
