The strong association of iodine with organic material and the presence of the cosmogenic radioisotope I make the iodine isotopic system useful in tracing and dating studies of organic materials and their derivatives. We present here results from two new applications of this system, investigations of gas hydrates from the Peru Margin (ODP 201, Site 1230) and of fluids collected from the fore ar...

In non-binary constraint satisfaction problems, the study of local consistencies that only prune values from domains has so far been largely limited to generalized arc consistency or weaker local consistency properties. This is in contrast with binary constraints where numerous such domain filtering consistencies have been proposed. In this paper we present a detailed theoretical, algorithmic a...

This paper presents a model to calculate tile tcInperature de-pmclcncc of effective permit tivit ies for a 1 Ietero?;eneous anisotropic medium containing multiphase scatterers. With the strong pcrmit-tivity fluctuation approach, the mc)del is developed to account for the clcctrodynamic scattering effect together with the cluasi-static characteristics of multiple spccics and sulxpecics of inhomo...

Race-specific disease resistance in plants is mediated by Resistance (R) proteins that recognize pathogen attack and initiate defence responses. Most R proteins contain a central NB-ARC domain and a C-terminal leucine-rich repeat (LRR) domain. We analyzed the intramolecular interaction of the LRR domain of tomato R protein Mi-1.2 with its N-terminus. We expressed the CC-NB-ARC and LRR parts in ...

Golumbic, M.C. and R.C. Laskar, Irredundancy in circular arc graphs, Discrete Applied Mathematics 44 (1993) 79-89. A set ofvertices Xis called irredundant if for every x in Xthe closed neighborhood N[x] contains a vertex which is not a member of N[X-x], the union of the closed neighborhoods of the other vertices. In this paper we show that for circular arc graphs the size of the maximum irredun...

We made simultaneous recordings from 48 bipolar electrodes to obtain epicardial isochronal maps during induced ventricular arrhythmias in dogs 3-5 days after ligation of the left anterior descending artery. There was strong evidence of a reentrant circuit (RC) that was discernible largely on the epicardial surface in 21% of ectopic beats that were analyzed. Epicardial recordings were of limited...

The morphology and distribution of volcanic edifices in terrains encodes the structure evolution underlying magma transport as well surface processes that shape landforms. How magmatic construction erosion interact on long timescales to sculpt these landscapes, however, remains poorly resolved. In Cascades arc, distributed mirror long-wavelength topography associated with crustal magmatism defi...

Abstract Back-arc spreading is a non-steady-state process exemplified by the repeated cycles of South Fiji and Lau Basins behind Tonga arc, Parece Vela Basin Mariana Trough arc. Spreading in these regions starts with rifting within volcanic arc before shifting to back-arc region where it develops into phase well-defined spreading. 2D thermo-mechanical subduction modeling incorporating transitio...

Day and Tripathi [K. Day, A. Tripathi, Unidirectional star graphs, Inform. Process. Lett. 45 (1993) 123–129] proposed an assignment of directions on the star graphs and derived attractive properties for the resulting directed graphs: an important one is that they are strongly connected. In [E. Cheng, M.J. Lipman, On the Day–Tripathi orientation of the star graphs: Connectivity, Inform. Process....

This paper presents an architecture for solving conditional linear-quadratic Gaussian (CLQG) influence diagrams (IDs) by Lazy Propagation (LP). A strong junction tree (SJT) is used to guide the elimination order whereas the marginalization operation is based on arc-reversal (AR). The use of AR for marginalization simplifies the implementation and gives the architecture a number of advantages. T...
