TEG is a new methodology for point-to-point messaging developed as a part of the Open MPI project. Initial performance measurements are presented, showing comparable ping-pong latencies in a single NIC configuration, but with bandwidths up to 30% higher than that achieved by other leading MPI implementations. Homogeneous dual-NIC configurations further improved performance, but the heterogeneou...
We briefly review the security of the ping-pong protocol in light of several attack scenarios suggested by various authors since the proposal of the protocol. We refute one recent attack on an ideal quantum channel, and show that a recent claim of falseness of our original security proof is erroneous.
The Vibrio harveyi NADPH-specific flavin reductase FRP follows a ping-pong mechanism but switches to a sequential mechanism in the luciferase-coupled reaction. The bound FMN co-isolated with FRP, while acting as a genuine cofactor in the single-enzyme reaction, functions in the luciferase-coupled reaction as a prebound substrate and is directly transferred to luciferase once it is reduced [Lei,...
Ultra-dense networks (UDNs) are considered as key 5G technologies. They provide mobile users a high transmission rate and efficient radio resource management. However, UDNs lead to the dense deployment of small base stations (BSs) that can cause stronger interference subsequently increase handover management complexity. At present, conventional triggering mechanism user equipment (UE) is only d...
This paper presents a handover optimization scheme in LTE for a variety of velocities. This scheme adjusts the time-to-trigger parameter based on received signal strength. The proposed algorithm demonstrates a more enhanced performance during a data link failure and ping-pong effect than existing algorithms focusing on a user’s position.
TEG is a new component-based methodology for point-to-point messaging. Developed as part of the Open MPI project, TEG provides a configurable fault-tolerant capability for high-performance messaging that utilizes multi-network interfaces where available. Initial performance comparisons with other MPI implementations show comparable ping-pong latencies, but with bandwidths up
1. Cytoplasmic acetoacetyl-CoA thiolase was highly purified in good yield from rat liver extracts. 2. Mg(2+) inhibits the rate of acetoacetyl-CoA thiolysis but not the rate of synthesis of acetoacetyl-CoA. Measurement of the velocity of thiolysis at varying Mg(2+) but fixed acetoacetyl-CoA concentrations gave evidence that the keto form of acetoacetyl-CoA is the true substrate. 3. Linear recipr...
