A major class of network emulation testbeds is based on the Utah Emulab design: a local cluster of experimental nodes interconnected through Ethernet switches using VLANs. The VLANs are configured dynamically to create multiple concurrent experimental topologies. This cluster architecture allows deterministic testbed operation and therefore repeatable experiments. This paper explores the inter-...

Electronic circuits require a wide variety of voltage levels to operate correctly. A DC/DC converter (DC/DC) is an electronic circuit used either to transform one voltage level to a different level; or to provide an isolation barrier for a voltage bus. DC/DCs are typically used in power distribution systems to provide a local voltage conversion, point of load voltage regulation or power bus iso...

A seventy year-old male was referred to our hospital to undergo radiofrequency catheter ablation (RFCA) for drug-refractory paroxysmal atrial fibrillation (AF). Pre-operative three-dimensional computed tomography revealed a unique left atrial (LA) roof vein. Electrophysiological findings showed expansion of the myocardial sleeve and local firing in the LA roof vein. We performed isolation of th...

Abstract The Mahalanobis distance between pairs of multivariate observations is used as a measure of similarity between the observations. The theoretical distribution is derived, and the result is used for judging on the degree of isolation of an observation. In case of spatially dependent data where spatial coordinates are available, different exploratory tools are introduced for studying the ...

The P element in Drosophila melanogaster preferentially transposes into nearby sites. The local insertions display a preferential orientation toward the starting element. We investigated the mechanism of the P-element local transposition by isolating and characterizing local insertions in the male germline. We designed a genetic screen employing a marker gene that is carried in the P element an...

This paper investigates original local update schemes for Cellular Automata (CA) in structural design. Local problems based on mathematical programming and optimality criteria are tested, allowing the isolation of an original local update scheme. The scheme consists of repeating analysis and optimality-based design rules locally. Several systematic experiments on various problem sizes are perfo...

a filtering power divider/power combiner based on half mode substrate integrated waveguide technology for high power applications is proposed. this design includes one half mode substrate integrated waveguide cavity, one matched load, and four sections of quarter-wavelength transmission lines. the high isolation between output ports is obtained by combining the half mode substrate integrated wa...

Two conceptual and methodological foundations of segregation studies are that (i) segregation involves more than one group, and (ii) segregation measures need to quantify how different population groups are distributed across space. Therefore, percentage of population belonging to a group is not an appropriate measure of segregation because it does not describe how populations are spread across...

Sexual deficits and other behavioral disturbances such as anxiety-like behaviors can be observed in animals that have undergone social isolation, especially in species having important social interactions. Using a model of protracted social isolation in adult rats, we observed increased anxiety-like behavior and deficits in both the latency to initiate sexual behavior and the latency to ejacula...

A caching scheme that uses query predicates to cache data on the client-side in a client-server relational database system was presented in [15]. The client-side cache (henceforth referred to as a SQL*Cache), loads query results dynamically in the course of transaction execution, and formulates a cache description based on the query predicates. SQL*Cache is associative in nature, in that it sup...
