Recent studies suggest a significant role for context in controlling the acquisition and extinction of simple operant responding. The present experiments examined the contextual control of a heterogeneous behavior chain. Rats first learned a chain in which a discriminative stimulus set the occasion for a procurement response (e.g., pulling a chain), which led to a second discriminative stimulus...

Plenty of approaches to stabilize chained nonholonomic systems have been proposed in the literature. However, the stabilization with constrained inputs is seldom addressed. This problem has practical importance since all physical nonholonomic systems have actuator limitations. In this article, a novel switching control design is proposed. The design strategy is inspired by the structural simila...

This poster paper presents the design and implementation of an RDFS reasoner based on a backward chaining approach and implemented on a clustered RDF triplestore. The system presented, called 4sr, uses 4store as base infrastructure. In order to achieve a highly scalable system we implemented the reasoning at the lowest level of the quad store, the bind operation. The bind operation in 4sr trave...

In this paper, we will introduce a new digital signature scheme based on the well-known problem: Syndrom Decoding (SD). It consists in chaining a set of linear-codes. Our scheme generates a short and fast signature. In addition to that, it has a smaller public key size than the McEliece signature introduced in[8]. The resulting matrix of chaining these codes forms the trap of our algorithm.The ...

BACKGROUND Examinations are necessary for assessment of student proficiency in medical education, but comparison of achievement across different cohorts in different tests is challenging. We applied psychometric test equating methods to compare student proficiency in two different examinations for a clinical anesthesiology course. METHODS Each examination contained 50 multiple choice items an...

multistage interconnection network. Various traffic control schemes have been proposed to handle hot-spot traffic [4–7, 17, 19, 24]. Among these schemes, the combining network [5, 6, 17], which can combine requests within a switching element accessing the same memory location, is an effective scheme for handling hot-spot traffic. It not only reduces network traffic, but also provides a fast syn...

Chylous ascites has rarely been reported in yellow nail syndrome. A case of chylous ascites in yellow nail syndrome is described which was treated successfully with dietary restriction of fat and supplements of medium chained triglycerides.

An efficient archive securing the integrity of VoIP-based two-party conversations is presented. The solution is based on chains of hashes and continuously chained electronic signatures. Security is concentrated in a single, efficient component, allowing for a detailed analysis.
