This work demonstrates the fabrication of microfluidic paper-based analytical devices (μPADs) suitable for the analysis of sub-microliter sample volumes. The wax-printing approach widely used for the patterning of paper substrates has been adapted to obtain high-resolution microfluidic structures patterned in filter paper. This has been achieved by replacing the hot plate heating method convent...

HPAM Sim is an execution-driven simulator of heterogeneous machines. HPAM Sim allows the simulation of target machines consisting of different processors and interconnection networks. HPAM Sim attempts to reduce simulation time by using lightweight threads and static augmentation. Additionally, simulation can be performed either in contention or non contention mode. The results of HPAM Sim simu...

This work presents a novel parallel micro evolutionary algorithm for scheduling tasks in distributed heterogeneous computing and grid environments. The scheduling problem in heterogeneous environments is NP-hard, so a significant effort has been made in order to develop an efficient method to provide good schedules in reduced execution times. The parallel micro evolutionary algorithm is impleme...

1 The efficient implementation of collective communication operations has received much attention. Initial efforts produced " optimal " trees based on network communication models that assumed equal point-to-point latencies between any two processes. This assumption is violated in most practical settings, however, particularly in heterogeneous systems such as clusters of SMPs and wide-area " co...

From 1992 to 2007, HERA, the first electron-proton collider, operated at cms energies of about 320GeV and allowed the investigation of deep-inelastic and photoproduction processes at the highest energy scales accessed thus far. This review is an introduction to, and a summary of, the main results obtained at HERA during its operation. To be published in Progress in Particle and Nuclear Physics ...

Clearly there are differences in the observed reactivities of the "heavily oxidized" surfaces of Mo(1 I0) prepared by Queeney et al. [1] and those prepared by us [2]. We note, however, that our study is in agreement with, and provides fresh insight into, the chemistry of high surface-area (HSA), "real-world" molybdate catalysts. The 3D oxide prepared by us (i) does not produce methyl radicals, ...

The model defines three basic units: diagnosis, control, and communication. They are characterized by defining their functionality and their sets of inputs and outputs. It also specifies patients’ clinical specific input data dissemination and the output’s list of diagnoses, built by fusing DUs’ results. DUs are seen as black boxes, abstracting the heterogeneity of their underlying classificati...

BACKGROUND Small number of clusters and large variation of cluster sizes commonly exist in cluster-randomized trials (CRTs) and are often the critical factors affecting the validity and efficiency of statistical analyses. F tests are commonly used in the generalized linear mixed model (GLMM) to test intervention effects in CRTs. The most challenging issue for the approximate Wald F test is the ...

Heterogeneous nuclear RNA from HeLa cells contains double-stranded regions that arise by base pairing of complementary sequences that exist as parts of the same molecule (intramolecular base pairing). When denatured, the RNA sequences that form the double-stranded regions hybridize rapidly to HeLa cell DNA, suggesting that they are transcribed from reiterated sites in the genome. The messenger ...

The D0 meson can decay to the wrong sign K+ π state either through a doubly Cabibbo suppressed decay or via mixing to the D0 state followed by the Cabibbo favoured decay D0 → K+π−. We measure the rate of wrong sign decays relative to the Cabibbo favoured decay to (0.383 ± 0.044 ± 0.022)% and give our sensitivity to a mixing signal. Contributed to the Proceedings of the International Europhysics...
