Implementations of state machine replication are prevalently using variants of Paxos or other leader-based protocols. Typically these protocols are also leader-centric, in the sense that the leader performs more work than the non-leader replicas. Such prot ...
The performance of most digital systems today is limited by the interconnect latency between logic and memory, rather than by the performance of logic or memory itself. Three- dimensional (3-D) integration using through-silicon-vias (TSVs) may provide a so ...
The complexity of stem cell niches poses a tremendous challenge to understanding mechanisms of extrinsic regulation of stem cell fate. In order to better understand niche signaling and its effect on stem cell fate choices, in vitro systems are being engine ...
In this paper, standard-cell based memories (SCMs) are proposed as an alternative to full-custom sub-VT SRAM macros for ultra-low-power systems requiring small memory blocks. The energy per memory access as well as the maximum achievable throughput in the ...
We consider single-hop broadcast packet erasure channels (BPEC) with degraded message sets and instantaneous feedback regularly available from all receivers, and demonstrate that the main principles of the virtual-queue-based algorithms in [1], which were ...
We propose an adaptive diffusion strategy with limited communication overhead by cutting off all links but one for each node in the network. We keep the “best” neighbor that has the smallest estimated variance-product measure and ignore the other neighbors ...
This work studies how to build wireless network protocols that achieve better reliability, lower delay and higher throughput than existing alternatives by using network coding and by exploiting the broadcast nature of the wireless channel. In the first par ...
Microwell arrays are cell culture and imaging platforms to assess cells at a single cell level and in high-throughput. They allow the spatial confinement of single cells in microfabricated cavities on a substrate and thus the continuous long-term observati ...
A new traffic-responsive feedback control strategy, heuristic ramp-metering coordination (HERO) that coordinates local ramp-metering actions in freeway networks is presented. The proposed coordination scheme is simple and reactive [i.e., based on readily a ...
Paxos is probably the most popular state machine replication protocol. Two optimizations that can greatly improve its performance are batching and pipelining. Nevertheless, tuning these two optimizations to achieve optimal performance can be challenging, a ...
