Coil sensitivity encoding for fast MRI. In:

by Klaas P Pruessmann , Markus Weiger , Markus B Scheidegger , Peter Boesiger - Proceedings of the ISMRM 6th Annual Meeting, , 1998
"... New theoretical and practical concepts are presented for considerably enhancing the performance of magnetic resonance imaging (MRI) by means of arrays of multiple receiver coils. Sensitivity encoding (SENSE) is based on the fact that receiver sensitivity generally has an encoding effect complementa ..."

contributions from a number of positions in the full FOV need to be separated. As depicted in The key to signal separation lies in the fact that in each single-coil image signal superposition occurs with different weights according to local coil sensitivities. Consider one pixel in the reduced FOV

Approximating the Maximum Weight Clique Using Replicator Dynamics

by Immanuel M. Bomze , Marcello Pelillo, Volker Stix , 2000
"... Given an undirected graph with weights on the vertices, the maximum weight clique problem (MWCP) is to find a subset of mutually adjacent vertices (i.e., a clique) having largest total weight. This is a generalization of the classical problem of finding the maximum cardinality clique of an unweig ..."

recently been much interest around neural network algorithms for the unweighted maximum clique problem, no effort has been directed so far towards its weighted counterpart. In this paper, we present a parallel, distributed heuristic for approximating the MWCP based on dynamics principles developed

The optical counterpart of the double degenerate Polar RX J1914+24

by Gavin Ramsay, Keith Mason, Pasi Hakala , 1998
"... Abstract. Cropper et al. presented X-ray observations of RX J1914+24 and claimed that the most likely interpretation of their data was that of a double degenerate Polar. Here we show the preliminary results of optical and further X-ray observations. We identify the optical counterpart and show that ..."

that no other period apart from the 569 sec period seen in X-rays is identified. Although the optical counterpart has no significant polarised flux in the I band, our ASCA spectrum (which is typical of a Polar) together with our photometric result adds weight to the conclusion that RX J1914+24 is the first

Parameterized Weighted Containment

by Guy Avni, Orna Kupferman
"... Abstract. Partially-specified systems and specifications are used in formal methods such as stepwise design and query checking. The goal of these methods is to explore the design or refine it by examining possible completions of the missing information. Existing methods consider a setting in which t ..."

, and C, with B being partial, the goal is to find an assignment to the missing costs in B so that we end up with B ′ for which A ≤ B ′ ≤ C, where ≤ is the weighted counterpart of containment. We also consider a one-sided version of the problem, where only A or only C are given in addition to B

Weighted automata algorithms

"... This chapter presents several fundamental algorithms for weighted automata and transducers. While the mathematical counterparts of weighted transducers, rational power series, have been extensively studied in the past [22, 54, 13, 36], several essential weighted transducer algorithms, e.g., composit ..."
