Kernel methods are known to be effective analyse complex objects by implicitly embedding them into some feature space. The approximate class-specific kernel spectral regression (ACS-KSR) method is a powerful tool for face verification. This consists of two steps: an eigenanalysis step and step, however, it may suffer from heavily computational overhead in practice, especially large-sample data ...

Molecular dynamics and many other particle based simulation techniques are often highly paralizable in principle. In practice many algorithms for concurrency can lead to irreproducible trajectories. We suggest a method for providing reproducible simulations that suffers only a small performance penalty. Results for scaling of the molecular dynamics code ESP to the KSRl are also given and the ef...

The parallel performance of the NWChem version 1.2 parallel direct-SCF code has been characterized on ve massively parallel supercomputers (IBM SP, Kendall Square KSR-2, Cray T3D and T3E, and Intel Touchstone Delta) using single-point energy calculations on seven molecules of varying size (up to 389 atoms) and composition ((rst-row atoms, halogens, and transition metals). We compare the perform...

Stretcher operation of the electron storage ring, KSR has been tested with 80 MeV electron beam. Beam injection with closed orbit control and beam extraction channel consisting of the electrostatic septum with 70 kV/cm and septum magnet of 5kG with septum thickness of 14 mm have been completed. Beam spill can be enlarged to ~1 s by the slow extraction with combined use of the third order resona...

This paper presents performance results for ZPL programs running on the Kendall Square Research KSR-2 and the Intel Paragon. Because ZPL is a data parallel language based on the Phase Abstractions programming model, these results complement earlier claims that the Phase Abstractions model can lead to portability across MIMD computers. The ZPL language and selected aspects of the compilation str...

Let A be a unital maximal full algebra of operator fields with base space [0, 1] and fibre algebras {At}t∈[0,1]k . We show that the stable rank of A is bounded above by the quantity supt∈[0,1]ksr(C([0, 1] )⊗ At). Here the symbol “sr” means stable rank. Using the above estimate, we compute the stable ranks of the C-algebras of the (possibly higher rank) discrete Heisenberg groups.

We prove a version of Schur–Weyl duality over finite fields. We prove that for any field k, if k has more than r elements, then Schur– Weyl duality holds for the rth tensor power of a finite dimensional vector space V . Moreover, if dimV is at least r + 1 then the natural map kSr → EndGL(V )(V ) is an isomorphism; this isomorphism may fail if dimk(V ) is not strictly larger than r.

The down-regulation of the high-molecular-weight isoforms of tropomyosin (TM) is considered to be an essential event in cellular transformation. In ras-transformed fibroblasts, the suppression of TM is dependent on the activity of the Raf-1 kinase; however, the requirement for other downstream effectors of Ras, such as MEK and ERK, is less clear. In this study, we have utilized the mitogen-acti...
