We discuss a gauged U(1)R supergravity on five-dimensional orbifold (S/Z2) in which a Z2-even U(1) gauge field takes part in the U(1)R gauging, and show the structure of Fayet-Iliopoulos (FI) terms allowed in such model. Some physical consequences of the FI terms are examined.
In this paper, several schemes of soft X-ray and hard X-ray free electron lasers (XFEL) and their progress are reviewed. Self-amplified spontaneous emission (SASE) schemes, the high gain harmonic generation (HGHG) scheme and various enhancement schemes through seeding and beam manipulations are discussed, especially in view of the generation of attosecond X-ray pulses. Our recent work on the ge...
Functional near-infrared imaging (fNIRI) is a non-invasive, low-cost and highly portable technique for assessing brain activity and functions. Both clinical and experimental evidence suggest that fNIRI is able to assess brain activity at associated regions during pain processing, indicating a strong possibility of using fNIRI-derived brain activity pattern as a biomarker for pain. However, it r...
The new standard IEEE std. 1596-1992, Scalable Coherence Interface (SCI)-provides novel possibilities to build data acquisition systems for large and very high rate experiments in High Energy Physics (HEP). The RD24 project at CERN started 2 years ago to investigate applications of SCI to data acquisition at the Large Hadron Collider (LHC). The participants come from CERN, universities and comp...
abstract purpose-the purpose of this paper is to review a sample of the literature relating to interpretive structural modelling (ism) and its deployment for modelling purposes in the area of supply chain management (scm). design/methodology/approach- the literature is examined from the three perspectives. first, concept of ism and examines ism as modelling technique. second, use of ism by the ...
In this paper we introduce a very low latency implementation of the Berkeley Sockets interface on top of the Dolphin SCI interconnect. Average one byte latencies as low as 2.31 microseconds are achieved. To our knowledge, this is the fastest sockets implementation in terms of latency. SCI SOCKET combines outstanding performance and seamless integration with legacy applications. This enables net...
| We present PVM-SCI, an implementation of the PVM 3.4 message passing standard for workstation clusters with scalable coherent interface (SCI). PVM-SCI provides two complementary communication schemes: the usual UDP/IP protocol for messages sent via PVM daemons, and a fast communication protocol that has been implemented directly on top of SCI for messages sent with the PvmRouteDirect directiv...
