Data from high throughput technologies, such as DNA microarrays, necessitated the development of new computational methodologies for analyzing the high dimensional information contained within the gene expression data. Liao's group suggested the use of network component analysis to predict transcription factor activities by integrating gene expression data from Escherichia coli with known conne...

We compute the hard photon production rate of a chemically non-equilibrated quark-gluon plasma. We assume that the plasma is already thermally equili-brated, i. e. describable by a temperature, but with a phase-space distribution that deviates from the Fermi/Bose distribution by a time dependent factor (fugacity). The photon spectrum is obtained by integrating the photon rate over the space-tim...

The conformal factor of the spacetime metric becomes dynamical due to the trace anomaly of matter fields. Its dynamics is described by an effective action which we quantize by canonical methods on the Einstein universeR×S3. We find an infinite tower of discrete states which satisfy the constraints of quantum diffeomorphism invariance. These physical states are in one-to-one correspondence with ...

A key successful factor for a knowledge management system is to promote and support semantic communication among people. This goal can be accomplished by integrating personal knowledge management tools with sharing tools that allow for merging semantic perspectives to create unified views, adapting behaviors to context, and finally learning from conversations to promote knowledge diffusion and ...

in this research, feasibility study of integrating thermal desalination unit with gas turbine (gt) has been investigated using retrofit and grass root design techniques  for lavan island oil refinery which is located in persian gulf. according to computed parameters on developed code for the power generation unit no.1 using ees (engineering equation solver) software, thermal efficiency of the g...

This paper proposes a novel framework for semantic indexing and retrieval in digital video. The components of the framework are probabilistic multimedia objects (multijects) and a network of such objects (multinets). The main contribution of this paper is a novel application of a factor graph framework to model the interactions in a network of multijects (multinet) at a semantic level. Factor g...
