This paper presents a new approach to implement fast broadcast and multicast operations in bidirectional wormhole Multistage Interconnection Networks (MIN) with loopback, as used in IBM SP1/SP2 network. The novelty lies in using multidestination message passing mechanism instead of single destination (unicast) messages. For broadcast/multicast operation, it is shown that a single worm with mult...

B7-H4, one of the costimulatory molecules of the B7 family, has been found to be widely expressed in many kinds of tumor tissues and to play an important part in tumor progression and poor prognosis. However, the role of B7-H4 in esophageal squamous cell carcinoma (ESCC) cells has not been elucidated. In this study, we found that, compared with normal esophageal tissue, B7-H4 was highly express...

This paper focuses on the secure transmission of wireless-powered relay systems with imperfect eavesdropper channel state information (ECSI). For efficient energy transfer and information relaying, a novel two-phase protocol is proposed, in which the relay operates in full-duplex (FD) mode to achieve simultaneous wireless power and information transmission. Compared with those existing protocol...

To be an effective platform for performance-sensitive real-time and embedded applications, off-the-shelf CORBA middleware must preserve the communication-layer quality of service (QoS) properties of applications end-to-end. However, the standard CORBA GIOP/IIOP interoperability protocols are not well suited for applications that cannot tolerate the message footprint size, latency, and jitter as...

Network performance in B-ISDN networks depends primarily on the three lower layers of the B-ISDN protocol : the physical layer, the ATM layer and the AAL layer [1,p267]. Network performance parameters for the ATM layer is the most important. And it includes six QoS parameters which used to measure the performance of the network for a given connection such as: cell loss ratio (CLR), maximum cell...

We propose a refinement to existing methods for span-restorable mesh capacity design to increase the capacity efficiency on sparse facility graphs. The resultant designs comprise a special class of restorable network that is intermediate between pure span restoration and path restoration. Most of the efficiency of path restoration is achieved by targeting chain sub-networks that ordinarily requ...

We have developed a design refinement to increase the capacity efficiency of span-restorable mesh networks on sparse facility graphs. The new approach views the network as a “meta-mesh of chain subnetworks.” This makes the prospect of WDM mesh networking more economically viable than with previous mesh-based designs where the average nodal degree is low. The meta-mesh graph is a homeomorphism o...

1 Dept. of Computer Science, The William Paterson University of New Jersey, Wayne, NJ 07470, USA 2 Wireless Speech and Data Processing, Nortel Networks, Montreal, QC, Canada, H3E 1H6 Abstract Software pipelining is a loop optimization technique that has been widely implemented in modern optimizing compilers. In order to fully utilize the instruction level parallelism of the recent VLIW DSP proc...

We present a software toolchain for constructing large-scale regular expression matching (REM) on FPGA. The software automates the conversion of regular expressions into compact and high-performance non-deterministic finite automata (RE-NFA) [17]. Assuming a fixed number of fan-out transitions per state, an n-state m-bytes-per-cycle regular expression matching engine (REME) can be constructed i...
