bacteriophage antibiotics. Streptonu,ces sp. RK-1441 was found to produce antibacteriophage antibiotics, RK-1441A and B, which are pyrrole[1,4]benzodiazepine group antib;otics related to neothramycin. Both RK-1441A and B had antibacteriophagc actiyity, The former she"'ed antimicrobial activity on a hypersensitive strain of E. coti t'or antitumor antibiotics, but the later d;d not show the activ...

OBJECTIVE To evaluate visual outcomes and complications after phacoemulsification in eyes with cataract and previous radial keratotomy (RK) cuts using different sizes of clear corneal incisions. METHODS The study was a retrospective study. Thirty eyes with cataract and previous RK underwent phacoemulsification and intraocular lens (IOL) implantation. Among them 7 eyes had 8 RK cuts, 13 eyes h...

The protein phosphatase inhibitor RK-682 is one of a number of potentially valuable tetronate polyketide natural products. Understanding how the tetronate ring is formed has been frustrated by the inaccessibility of the putative substrates. We report the heterologous expression of rk genes in Saccharopolyspora erythraea and reconstitution of the RK-682 pathway using recombinant enzymes, and we ...

Example 3. For k′/k a finite separable extension and H any linear algebraic k-group, we have H ↪−→ Rk′/k(Hk′) =: H ′, where Rk′/k(Hk′) is the Weil restriction functor (which is representable by a linear algebraic k-group). This functor is defined by Rk′/k(Hk′)(A) = Hk′(A⊗k k′), so the injection H ↪−→ Rk′/k(Hk′) is given by sending a k-morphism SpecA→ H to its base change by k′. Then we have [H ...

In this demo, we present Virt/RK, a real-time virtualization framework specifically developed for multi-core platforms. Virt/RK combines (i) a theoretical framework to analyze the timing requirements of virtualized workloads, (ii) a real-time hypervisor to host multiple real-time guest OSs, and (iii) a suite of tools to allocate resources to real-time applications hosted in a virtualized enviro...

In this paper, we consider the parallel solution of nonstii ordinary diierential equations with two diierent classes of Runge-Kutta (RK) methods providing embedded solutions: classical embedded RK methods and iterated RK methods which were constructed especially for parallel execution. For embedded Runge-Kutta methods, mainly the potential system parallelism is exploited. Iterated RK methods pr...

In this paper, a new method of analysis for second order initial value problems using the RKButcher algorithms is presented. To illustrate the effectiveness of the RK-Butcher algorithms, seven problems of different kinds have been considered and the solutions were obtained using the RK method based on Arithmetic mean (RKAM), Centroidal mean (RKCeM) and the RK-Butcher Algorithms and are compared...

Portable RK is a portable implementation of a resource kernel, a resource-centric approach to build a real-time kernel that provides explicit timely, guaranteed and enforced access by applications to system resources [13]. Portable RK is designed to work with widely available operating systems with minimal changes. This facilitates experimentation in a familiar software environment and helps th...
