Product ion yields in postsource decay and photodissociation at 193 and 266 nm were measured for some peptide ions without a basic amino acid residue ([Y(6) + H](+), [F(5) + H](+), and [YPFVEPI + H](+)) generated by matrix-assisted laser desorption ionization (MALDI). Data indicated statistical nature for the dissociation processes. Assuming that peptide ions formed by MALDI are in thermal equi...

Thin-layer spectroelectrochemical methods have been employed to measure the reduction potentials of the blue copper in Polyporus versicolor laccase (EC 1.10.3.2) between 7 degrees C and 41 degrees C (0.2 M sodium phosphate, pH 5.4). Thermodynamic parameters are: DeltaS degrees = -13.9 +/- 2 cal/mol-K; DeltaH degrees = -22.1 +/- 0.5 kcal/mol; E degrees (25 degrees C) = 780 +/- 3 mV vs. the norma...

For evaluating a hedging strategy we have to know at every instant the solution of the Cauchy problem for a parabolic equation (the value of the hedging portfolio) and its derivatives (the deltas). We suggest to nd these magnitudes by Monte Carlo simulation of the corresponding system of stochastic di erential equations using weak solution schemes. It turns out that with one and the same contro...

An increasing number of scientific communities rely on Semantic Web ontologies to share and interpret data within and across research domains. These common knowledge representation resources are usually developed and maintained manually and essentially co-evolve along with experimental evidence produced by scientists worldwide. Detecting automatically the differences between (two) versions of t...

This paper presents a low complexity table-based approach to delta correlation prefetching. Our approach uses a table indexed by the load address which stores the latest deltas observed. By storing deltas rather than full miss addresses, considerable space is saved while making pattern matching easier. The delta-history can predict repeating patterns with long periods by using delta correlation...

Mars' transition from an early "warm and wet" to the "cold dry" environment left fingerprints on geological record of fluvial activity Mars. The morphological mineralogical observations aqueous provided varying constraints condition duration liquid water martian surface. In this study, we surveyed mineralogy alluvial fans deltas investigated hydrated silica-bearing deposits associated with thes...

Abstract Understanding the way fluvially transported materials are partitioned in river deltas is essential for predicting their morphological change and fate of environmental constituents contaminants. Translating water‐based partitioning estimates into fluxes nonwater often difficult to constrain because most not uniformly distributed water column may have characteristic transport pathways th...

Giving the fact that manufacturing industry is still the engine of economic development in developing countries, China pays special attention to the development of manufacturing industry, especially the hi-tech industry. This paper takes the manufacture of medicine as an example, aiming to investigate the development status of the manufacture of medicine in Yangtze River and Pearl River Deltas,...
