Normally torsion-free lexsegment ideals

In this paper we characterize all the lexsegment ideals which are normally torsion-free. Our characterization is given in terms of the ends of the lexsegment. We also prove that the property of being normally torsion-free is equivalent to the property of the depth function of being constant

Sectorial convergence of U-statistics

In this note we show that almost sure convergence to zero of symmetrized U-statistics indexed by a linear sector in Z^d_+ is equivalent to convergence along the diagonal of Z^d_+, as it is considered in Lata\la and Zinn [Ann. Probab. 28 (2000) 1908-1924]. Comparisons with similar results for sums of multi-indexed i.i.d. random variables are also made.Comment: Published at http://dx.doi.org/10.1214/009117904000001080 in the Annals of Probability (http://www.imstat.org/aop/) by the Institute of Mathematical Statistics (http://www.imstat.org

INTEGRATING CRM SOFTWARE APPLICATIONS

Scientists, end users of CRM applications and producers of CRM software, all come to an agreement when talking about the idea of CRM, the CRM strategy or the term CRM. The main aspect is that CRM can be analyzed from two different points of view: CRM – the marketing strategy and CRM – the software. The first term refers to establishing some personalized relationships with the customers that can be afterwards easily managed. This way, it can determine at any time the past client relations, the products (or services) that the customers bought, the products’ range, the products’ price, the type of delivery, all this information being used in anticipation of the future sales. All these things can be physically achieved through a CRM software application whose main function is to properly manage the information relating to customers and to enable personalized communication with them (via e-mail, phone, fax, mail).CRM, customer, marketing

Microclimate simulation of climate change impacts in a maize canopy

Effects of possible climate modification on maize plant features have been evaluated by using the simulation model of Goudriaan for local climatic conditions and locally measured plant characteristics. Moderate climate modifications were hypothesized. According to the purpose of detecting local impacts of climate change, researches were made on the microclimate of maize canopies. In the energy transport of the plant stand, no shift has been experienced to the direction of the latent heat as it was expected because of the effect of warming up and decrease of precipitation. The changes of stomatal resistance and inside canopy air temperature suggested that the natural water supply will probably not cover the water demand of the plant, if the climate change is more intensive, therefore farmers must prepare to irrigated cultivation and to apply different agro-technical methods to save the water supplies of the ground

Fredholm theory for elliptic operators on quasi-asymptotically conical spaces

We consider the mapping properties of generalized Laplace-type operators ${\mathcal L} = \nabla^* \nabla + {\mathcal R}$ on the class of quasi-asymptotically conical (QAC) spaces, which provide a Riemannian generalization of the QALE manifolds considered by Joyce. Our main result gives conditions under which such operators are Fredholm when between certain weighted Sobolev or weighted H\"older spaces. These are generalizations of well-known theorems in the asymptotically conical (or asymptotically Euclidean) setting, and also sharpen and extend corresponding theorems by Joyce. The methods here are based on heat kernel estimates originating from old ideas of Moser and Nash, as developed further by Grigor'yan and Saloff-Coste. As demonstrated by Joyce's work, the QAC spaces here contain many examples of gravitational instantons, and this work is motivated by various applications to manifolds with special holonomy
