Reactions o f photolytically generated SOJ with 2'-deoxyuridine-5 '-phosphate (5 '-dU M P), uridine-5 '-phosphate (5 '-U M P) and thym idine-5 '-phosphate (5'-dTM P) were studied by ESR spectroscopy in aqueous solution under anoxic conditions. From 5'-dU M P and 5 '-U M P the 5',5-cyclic phosphate-6 -yl radicals 10 and 11 were generated (pH 2 -1 1 ) whereas from 5 '-dTM P at .pH 3 8 the 5,6-dih...

Introduction: An accurate and representative catalog of impact craters on the surface of the Moon is necessary to infer information about the age of surfaces and the sequence of geological events [1]. The existing global catalogs of lunar craters contain ~2700 craters [2] and ~8500 craters [3], respectively. They suffer from uneven areal coverage as they were compiled from images having differe...

We present a system for automatic music annotation that leverages temporal (e.g., rhythmical) aspects as well as timbral content. Our system estimates a dynamic texture mixture (DTM) density over times series of acoustic features (instead of on individual features) for each tag in a semantic vocabulary. When analyzing a new song, our system processes the time series of acoustic features of the ...

Network-enabled server (NES) environments are valuable candidates to provide simple computing Grid access. These environments allow transparent access to a set of computational servers via Remote Procedure Call mechanisms. In this context, a challenge is to increase performances by decreasing data traffic. This paper presents DTM (Data Tree Manager), a data management service for NES environmen...

Using high resolution optical satellite imagery for automatic DTM generation the validation of the digital terrain model becomes an issue. This problem is easily to overcome if a DTM already exists, as given in various European countries. For the validation of the MOMS02-P camera experiment the outcome of the data take M2P083C of March 14, 1997 is compared with the archived DTM of the Bavarian ...

Further to a recent controversy on whether or not the differential transformation method (DTM) for solving a differential equation is purely and solely the traditional Taylor series method, it is emphasized that the DTM is currently used as a technique for calculating the power series of the solution (in terms of the initial value parameters) including, sometimes, a piecewise analytic continuat...

In this paper, approximate analytical solution of SIRC model associated with the evolution of influenza A disease in human population is acquired by the modified differential transform method (MDTM). The differential transform method (DTM) is mentioned in summary. MDTM can be obtained from DTM applied to Laplace, inverse Laplace transform and padé approximant. The MDTM is used to increase the a...

It is the aim of this paper to investigate a suitable approach to compute solutions of the powerful Michaelis-Menten enzyme reaction equation with less computational effort. We obtain analytical-numerical solutions using piecewise finite series by means of the differential transformation method, DTM. In addition, we compute a global analytical solution by a modal series expansion. The Michaelis...

In this paper, an aproximate analytical method called the differential transform method (DTM) is used as a tool to give approximate solutions of nonlinear oscillators with fractional nonlinearites. The differential transformation method is described in a nuthsell. DTM can simply be applied to linear or nonlinear problems and reduces the required computational effort. The proposed scheme is base...
