We present conditions under which verb phrases are elided based on a corpus of positive and negative examples. Factor that affect verb phrase ellipsis include: the distance between antecedent and ellipsis site, the syntactic relation between antecedent and ellipsis site, and the presence or absence of adjuncts. Building on these results, we examine where in the generation architecture a trainab...

Ca(2+) signals are commonly measured using fluorescent Ca(2+) indicators and microscopy techniques, but manual analysis of Ca(2+) measurements is time consuming and subject to bias. Automated region of interest (ROI) detection algorithms have been employed for identification of Ca(2+) signals in one-dimensional line scan images, but currently there is no process to integrate acquisition and ana...

Partitive set families are families of sets that can be quite large, but have a compact, recursive representation in the form of a tree. This tree is a common generalization of PQ trees, the modular decomposition of graphs, certain decompositions of boolean functions, and decompositions that arise on a variety of other combinatorial structures. We describe natural operators on partitive set fam...

In this paper cellular automata (CA) are applied to construct a symmetric-key encryption algorithm. A new block cipher based on one dimensional, uniform and reversible CA is proposed. A class of CA with rules specifically constructed to be reversible is used. The algorithm uses 224 bit key. It is shown that the algorithm satisfies safety criterion called Strict Avalanche Criterion. Due to a hug...

This paper presents an advanced method in urban growth modeling to discover transition rules of cellular automata (CA) using the artificial bee colony (ABC) optimization algorithm. Also, comparisons between the simulation results of CA models optimized by the ABC algorithm and the particle swarm optimization algorithms (PSO) as intelligent approaches were performed to evaluate the potential of ...

It is almost cliché to say that there has been an explosion in the amount of research on leadership in a cross-cultural context. In this review, we describe major advances and emerging patterns in this research domain over the last several years. Our starting point for this update is roughly 1996–1997, since those are the dates of two important reviews of the cross-cultural leadership literatur...
