This paper presents a Process History Capture System (PHCS) as a logging mechanism for distributed long running business processes executing over Delta-Enabled Grid Services (DEGS). A DEGS is a Grid Service with an enhanced interface to access incremental data changes, known as deltas, associated with service execution in the context of global processes. The PHCS captures process execution cont...

In the past, most researchers concentrated on the continuity of ridge structures. Because the principal Gabor basis functions (PGBFs) only have large response values with similar orientation and spatial-frequency, a local fingerprint image is represented by a PGBF. We, on the contrast, focus our attention on the discontinuity of ridge structures. This is because the important features (includin...

BACKGROUND Site-specific protein-DNA complexes vary greatly in structural properties and in the thermodynamic strategy for achieving an appropriate binding free energy. A better understanding of the structural and energetic engineering principles might lead to rational methods for modification or design of such proteins. RESULTS A novel analysis of ten site-specific protein-DNA complexes reve...

River deltas grow in large part through repeated cycles of lobe construction and channel avulsion. Understanding avulsion cycles is important for coastal restoration and ecology, land management, and flood hazard mitigation. Emerging theories suggest that river avulsions on lowland deltas are controlled by backwater hydrodynamics; however, our knowledge of backwater-controlled avulsion cycles i...

Heat-inactivation studies were carried out on the two primary erythrocyte carbonic anhydrase isoenzymes, CA I and CA II, and the secondary isoenzyme of CA I, CA I (+1). In addition, two genetic variants of human isoenzyme CA I, CA Id Michigan (100 Thr-->Lys) and CA If London (102 Glu-->Lys), and one variant of isoenzyme CA II, CA IIh (251 Asn-->Asp), were similarly analysed. The first-order rat...

This paper presents our results with monitoring data dependencies among concurrently executing, distributed processes that execute over Grid Services. The research has been conducted in the context of the DeltaGrid project, focusing on the development of a semantically-robust execution environment for the composition of Grid Services. Delta-Enabled Grid Services (DEGS) are a foundational aspect...

The world’s largest deltas are densely populated, of significant economic importance and among the most valuable coastal ecosystems. Projected twenty-first century sea-level rise (SLR) poses a threat to these low-lying coastal environments with inhabitants, resources and ecology becoming increasingly vulnerable to flooding. Large spatial differences exist in the parameters shaping the world’s d...
