The assessment of seismic performance of existing structures is becoming an important problem in earthquake engineering. Some important ructures are considerably old and, therefore, their strengths and ductilities are less than strength and ductility demands because of changes in codes and design methodologies. Such structures must be strengthened to resist future earthquakes. First, a structur...

We prove matching upper and lower bounds for the Minimum Steiner Tree (MStT) problem within the adaptive priority stack model introduced by Borodin, Cashman, and Magen [2] and lower bounds within the adaptive priority queue model introduced here. These models, which are extensions of the adaptive priority model of Borodin, Nielson, and Rackoff [3], are said to capture reasonable primal-dual and...

Memory-augmented neural networks equip a recurrent network with an explicit memory to support tasks that require information storage without interference over long times. A key motivation for such research is perform classic computation tasks, as parsing. However, memory-augmented are notoriously hard train, requiring many backpropagation epochs and lot of data. In this paper, we introduce the ...

Typical sampling profilers periodically interrupt the observed application and record a stack trace of its threads, i.e., the executing methods and callers. The entirety of the collected samples gives a statistical picture of where the application spends its time. However, interrupting application threads and delaying their execution while building a stack trace can cause a significant performa...

A novel stack passivation scheme, in which plasma silicon nitride (SiN) is stacked on top of a rapid thennal SiO? (RTO) layer, is developed to attain a surface recombination velocity (S) approaching 10 em/s at the L3 O-cm p-typc (l00) silicon surfaee_ Such low S is achieved by the stack cven when the RTO and SiN films "I<ilvldllally yield considerably poorer surface passivation. Critical to ach...

We have previously discovered that probes containing runs of four or more contiguous guanines are not reliable for measuring gene expression in the Human HG_U133A Affymetrix GeneChip data. These probes are not correlated with other members of their probe set, but they are correlated with each other. We now extend our analysis to different 3' GeneChip designs of mouse, rat, and human. We find th...

Applicative (functional) programming has long been advocated on theoretical grounds as the formal properties of such programs are simple and elegant. Recently, there has been a trend to bring the applicative approach into the practical arena as a software development tool [2] and even as a programming vehicle [1,6]. Unfortunately, the requirement that operations be side-effect free makes effici...
