Remote sensing (from ground-, airplane-, balloon-, or satellite-based platforms) is a powerful and versatile tool to estimate profiles of atmospheric temperature, trace gases, etc. and has been established as indispensable for research on climate change, stratospheric ozone depletion etc. An essential prerequisite is the accurate and complete knowledge of the absorption properties of the atmosp...

This paper presents experimental data from our research on stability of parallel programs and cross-machine performance prediction on multicomputers. We characterize program behavior by an execution graph, obtained from running an instrumented version of the program. We assess program stability using time perturbations, and analyze the resulting execution graphs with an approximation of a graph...

MOTIVATION Given inputs extracted from an aligned column of DNA bases and the underlying Perkin Elmer Applied Biosystems (ABI) fluorescent traces, our goal is to train a neural network to determine correctly the consensus base for the column. Choosing an appropriate network input representation is critical to success in this task. We empirically compare five representations; one uses only base ...

Copper (Cu) is a micronutrient that has roles in photosynthesis, respiration, antioxidant activity, cell wall metabolism and hormone perception. Excess Cu is toxic and therefore its delivery has to be tightly regulated. Recent progress in the study of Cu homeostasis has revealed not only components of the Cu delivery machinery but also regulatory systems that control Cu-protein expression and c...

The trace fossil Gyrochorte is common in Upper Jurassic siliciclastic rocks of the Kachchh Basin, western India. In the Kimmeridgian Katrol Formation, Gyrochorte comosa Heer, 1865 is tied to storm-generated fine-grained sandstones and exhibits an internal structure composed of double arches in cross-section, confirming the three-dimensional nature of the trace fossil and its interpretation as p...

In order to prepare a high capacity packing material for solid-phase extraction with specific recognition ability of trace ractopamine in biological samples, uniformly-sized, molecularly imprinted polymers (MIPs) were prepared by a multi-step swelling and polymerization method using methacrylic acid as a functional monomer, ethylene glycol dimethacrylate as a cross-linker, and toluene as a poro...

Traffic aggregation is a basic networking operation that merges separate traffic streams in network switching and cross-connect nodes. This paper discusses the experimental results on a generalized and protocol-independent self-similar traffic generator based on the RPG model of OPNET. The aggregation processes results from merging of multiple traffic traces with various Hurst parameters, where...

an ex-situ experiment to assess the metal extractive potential of fourteen agriculture plants (vigna unguiculata, gossypium hirsutum, jatropha curcas, etc.) was conducted on magnesite mines which had above permissible levels of cadmium and lead. there was no much difference in the total chlorophyll a and b, carbohydrate and protein contents in the plants grown in the mining soil and adjacent co...

‘Contamination’ is a comparative term. In Britain at least, contaminants are trace substances; in the context of food they are distinguished from additives by whether or not there is an intention that the substances should be present when the food is consumed or prepared for consumption. Contaminants may be of natural or of technological origin: and technological contaminants may be direct or i...

Typing systems define the admissible structures and behaviours of models formed by their instances, possibly defining relations among types in terms of inheritance and composition. Such a general notion is at the basis both of object-oriented analysis and design, and of metamodeling techniques, for both of which the relations with the field of graph transformations have been explored [10, 9]. W...
