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...
Janus is a language designed for distributed constraint programming 12]. This paper describes jc, an eecient and portable sequential implementation of Janus, which compiles Janus programs down to C code. Careful attention to the C code generated, together with some simple local optimizations, allows the system to have fairly good performance despite the lack (at this time) of global ow analysis...
Novel threadlike structures, so-called Bonghan ducts (BHDs), were recently rediscovered inside large caliber lymphatic vessels using two different staining dyes in rabbits (Janus green B and Alcian blue) and fluorescent nanoparticles in rats. These three methods have the drawback of injecting chemical agents into the lymphatic vessels, which might damage the BHD and hinder further investigation...
In 1891 Guttmann and Ehrlich (P. Guttmann and P. Ehrlich, Berlin Klin. Wochenschr. 28:953-956, 1891) were the first to report the antimalarial properties of a synthetic, rather than a natural, material when they described the clinical cure of two patients after oral administration of a thiazine dye, methylene blue. Since that time, sporadic reports of the antimalarial properties of several xant...
