We tested the effect of anti-sense RNA on the replication of avian retroviruses in cultured cells. The replication of a recombinant retrovirus carrying a neomycin resistance gene (neor) in the anti-sense orientation was blocked when the cells expressed high steady-state levels of RNA molecules with neor in sequence in the sense was blocked when the cells(More)
4-Chloromethylbiphenyl (4CMB), benzyl chloride (BC) and 4-hydroxymethyl-biphenyl (4HMB) were tested for biological activity in the following assays: (i) the Salmonella/microsome assay; (ii) a bacterial 'fluctuation' assays; (iii) a DNA repair assay in Hela cells, and (iv) a mouse lymphoma mutation assay. 4CMB was active in assays (i), (ii) and (iii) but not(More)
This paper describes an implementation of generic MPI-2 single-sided communications for SUN-MPI. Our implementation is layered on top of point-to-point MPI communications and therefore can be adapted to other MPI implementations. The code is designed to co-exist with other MPI-2 single-sided implementations (for example, direct use of shared memory)(More)
Recent efforts to simplify network data plane programming focus on providing simple, high-level domain-specific languages (DSLs). In the case of software switches, data plane programs are written in these DSLs and then compiled to run on CPU-based architecture. However, the simplicity of these DSLs, along with the lack of low-level interfaces exposed by the(More)
An examination has been made of some of the parameters which can affect mutant numbers in the Salmonella/microsome assay. The type of minimal media plates used for the assay and the concentration of glucose-6-phosphate, one of the co-factors necessary for mono-oxygenase action, had no effect on mutant numbers. Increases in mutated bacteria resulted from the(More)
Recent work on simplifying data plane programming focuses on providing simple, high-level domain-specific languages (DSLs). These languages hide the complex and intricate details of the underlying switching substrate. Programmers write their data-plane programs in these languages which are then compiled to run on a given switch target, which further runs on(More)
With FPGAs emerging as a promising accelerator for general-purpose computing, there is a strong demand to make them accessible to software developers. Recent advances in OpenCL compilers for FPGAs pave the way for synthesizing FPGA hardware from OpenCL kernel code. To enable broader adoption of this paradigm, significant challenges remain.
