Encapsulating Multiple Communication-Cost Metrics in Partitioning Sparse Rectangular Matrices for Parallel Matrix-Vector Multiplies
"... This paper addresses the problem of one-dimensional partitioning of structurally unsymmetricsquare and rectangular sparse matrices for parallel matrix-vector and matrix-transposevector multiplies. The objective is to minimize the communication cost while maintaining the balance on computational load ..."

loads of processors. Most of the existing partitioning models consider only the total message volume hoping that minimizing this communication-cost metric is likely to reduce other metrics. However, the total message latency (start-up time) may be more important than the total message volume
Regionally reduced brain volume, altered serotonin neurochemistry, and abnormal behavior in mice null for the circadian rhythm output gene Magel2.
- Am. J. Med.
, 2009
"... Magel2 belongs to the MAGE/necdin family of proteins, which have roles in cell cycle, differentiation, and apoptosis. The Magel2 gene is expressed in various brain regions, most notably the hypothalamus. Mice with a targeted deletion of Magel2 display hypoactivity, blunted circadian rhythm, decreas ..."

Volume 1 – No. 12 Implementation of Energy Efficient Integer Wavelet Transform in Spartan 3E FPGA
"... In this paper, we present an evaluation of various wavelet filters in the context of an energy efficient integer wavelet transform on SPARTAN 3E FPGA. The usage of different wavelet filters (Daubechies-9/7, Daubechies-5/3, Haar, etc.) for differential frames is investigated, where we mainly focus on ..."

energy efficient, adaptive data codec for image and video that can significantly minimize the energy required for wireless image communication, while meeting bandwidth constraints of the wireless networks, as the image quality and latency constraints of the wireless service. In this paper, the optimum
FW-DAS: Fast Wireless Data Access Scheme in
"... Abstract—In wireless data access applications, it is essential to reduce both the access latency and the wireless traffic volume. In this paper, we propose a fast wireless data access scheme (FW-DAS) for wireless data access applications in which data objects are frequently updated and fast access t ..."

to data objects is indispensable. In FW-DAS, different operation modes are defined depending on the data object popularity, and only popular data objects are proactively pushed to the access point/base station in order to minimize the access latency while mitigating the traffic load over the wireless link
Collection Tree Protocol
"... This paper presents and evaluates two principles for designing robust, reliable, and efficient collection protocols. These principles allow a protocol to benefit from accurate and agile link estimators by handling the dynamism such estimators introduce to routing tables. The first is datapath valida ..."

-free and interference-prone channels. In all cases, CTP delivers> 90 % of packets. Many experiments achieve 99.9%. Compared to standard beaconing, CTP sends 73 % fewer beacons while reducing topology repair latency by 99.8%. Finally, when using low-power link layers, CTP has duty cycles of 3 % while supporting

Enhancing MAC Coordination to Boost Spatial Reuse in IEEE 802.11 Ad Hoc Networks
"... Abstract — In a wireless ad hoc network where multi-hop traffic dominates the network, spatial reuse has an enormous impact on the network performance in terms of end-to-end throughput and delay characteristics. In this paper, we investigate the MAC coordination of persistent flows in 802.11 ad hoc ..."
