Several maze shapes are used to test spatial navigation performance and behavioral phenotypes. Traditionally, each experiment requires a unique shape, thus requiring several separate mazes in different configurations. The geometry cannot be reconfigured single environment accommodate scalability reproducibility. reconfigurable is approach address the limitations, allowing quick flexible configu...

Introduction The OWL 2 QL ontology language [11], based upon the description logic DL-LiteR, is considered particularly well suited for applications involving large amounts of data. While the data complexity of querying OWL 2 QL knowledge bases is well understood, far less is known about combined complexity of conjunctive query (CQ) answering for restricted classes of conjunctive queries. By co...

Bipolar cells (BCs) are critical relay neurons in the retina that are organized into parallel signaling pathways. The three main signaling pathways in the mammalian retina are the rod, ON cone, and OFF cone BCs. Rod BCs mediate incrementing dim light signals from rods, and ON cone and OFF cone BCs mediate incrementing and decrementing brighter light signals from cones, respectively. The outputs...

Many new applications like groupware systems, news and file distribution or audio/video systems are based on multi-cast as a prerequisite for scalability. Many of these applications need the multicast support to be reliable, which is realized in a scalable way by tree based multicast transport protocols, where the receivers are organized in a ACK tree. Tree based approaches raise the problem of...

Tree-based protocols are ubiquitous in distributed systems. They are flexible, they perform generally well, and, in static conditions, their analysis is mostly simple. Under churn, however, node joins and failures can have complex global effects on the tree overlays, making analysis surprisingly subtle. To our knowledge, few prior analytic results for performance estimation of tree based protoc...

To design methodologies that will allow researchers to directly correlate the results of adaptive control experiments with physiochemical control pathways in arbitrary complex molecular systems it is imperative that prototype systems are developed and that exigent control pathways are understood. We have been interested in the results of adaptive control experiments in our laboratory involving ...

We present an idea of efficient query answering over an RDF dataset employing a consumer-grade graphic card for an efficient computation. We consider tree-shaped SPARQL queries and static datasets, to facilitate data mining over RDF graphs in warehouse-like setups. Reasons to see the poster: a) presentation of the approach with examples; b) possibility of discussion about the implementation det...

This paper concerns the problem of consensus tracking for multiagent systems with a dynamical leader. In particular, it proposes the corresponding explicit control laws for multiple first-order nonlinear systems, second-order nonlinear systems, and quite general nonlinear systems based on the leader-follower and the tree shaped network topologies. Several numerical simulations are given to veri...

Tree mortality is a key process underlying forest dynamics and community assembly. Understanding how tree mortality is driven by simultaneous drivers is needed to evaluate potential effects of climate change on forest composition. Using repeat-measure information from c. 400,000 trees from the Spanish Forest Inventory, we quantified the relative importance of tree size, competition, climate and...

New applications of data mining, such as in biology, bioinformatics, or sociology, are faced with large datasets structured as graphs. We introduce a novel class of tree-shaped patterns called tree queries, and present algorithms for mining tree queries and tree-query associations in a large data graph. Novel about our class of patterns is that they can contain constants, and can contain existe...
