The development of software for scientific applications that rest on dynamic or irregular meshes causes many problems because of the conflicting issues of flexibility and efficiency. This dissertation addresses these problems in the following way. Firstly, it applies the ideas of domain engineering to the field of data-parallel applications in order to design reusable software products that acc...
We present JANUS, a speech-to-speech translation system that utilizes diverse processing strategies, including connectionist learning, traditional AI knowledge representation approaches, dynamic programming, and stochastic techniques. JANUS translates continuously spoken English and German into German, English, and Japanese. JANUS currently achieves 87% translation fidelity from English speech ...
We study several aspects of generalized Janus configuration, which includes a theta term. We investigate the vacuum structure of the theory and find that unlike the Janus configuration without theta term there is no nontrivial vacuum. We also discuss BPS soliton configuration both by supersymmetry analysis and from energy functional. The half BPS configurations could be realized by introducing ...
We describe Janus, an application-driven architecture for Monte Carlo simulations of spin glasses. Janus is a massively parallel architecture, based on reconfigurable FPGA nodes; it offers two orders of magnitude better performance than commodity systems for spin glass applications. The first generation Janus machine has been operational since early 2008; we are currently developing a new gener...
Here, the influence of various surface modifications on self-propelled motion of laser-heated goldcapped Janus particles is investigated. Wide-field laser heating of the gold hemisphere induces an asymmetric temperature profile around the particles resulting in thermophoretic self-propulsion [1]. Besides the desired directed translational motion also rotational diffusion of the Janus particles ...
Janus emulsion assays that rely on carbohydrate-lectin binding for the detection of Escherichia coli bacteria are described. Surfactants containing mannose are self-assembled at the surface of Janus droplets to produce particles with lectin binding sites. Janus droplets orient in a vertical direction as a result of the difference in densities between the hydrocarbon and fluorocarbon solvents. B...
We report on Janus subcompartmentalized assemblies with enzyme loaded liposomes entrapped within a polymer carrier capsule - Janus subcompartmentalized microreactors. The concept is based on the use of Pickering emulsions and the subsequent deposition of interacting liposomes and polymer layers. We demonstrate the adjustment of the size of the Janus domains and the control over the amount of tr...
Janus kinase 2 (JAK2) is an essential intracellular signal transducer for numerous cytokines and hormones. To examine how JAK2 structural modifications can affect cellular physiology, we created expression vectors for chimeric proteins containing an enhanced green fluorescent protein (EGFP) fused to rat JAK2 (EGFP/rJAK2), and a kinase-inactive variant, EGFP/rJAK2(K882E). The properties of EGFP/...
The Janus cassette permits marker-free allelic replacement or knockout in streptomycin-resistant Streptococcus pneumoniae (pneumococcus) through sequential positive and negative selection. Spontaneous revertants of Janus can lead to high level of false-positives during negative selection, which necessitate a time-consuming post-selection screening process. We hypothesized that an additional cou...
