We present the data acquired by the TAROT automated observatory on the afterglow of GRB 020531. Up to now, no convincing afterglow emission has been reported for this short/hard GRB at any wavelength, including X-ray and optical. The combination of our early limits, with other published data allows us to put severe constraints on the afterglow magnitude and light curve. The limiting magnitude i...

Recent years have seen a surge of interest in computational complexity results in card games. We focus in this paper on trick-taking card games, extending a study started in 2013. This class ranges from WHIST and CONTRACT BRIDGE to SKAT and TAROT. We investigate how the number of cards per suit, the ranks, impacts the complexity of solving arbitrary positions. We prove that 2 distinct ranks are...

The micropyle number in the ova of sturgeon species from the South Caspian Sea was investigated. The study was conducted on female broodfishes of three species of sturgeon (Persian sturgeon Acipenser persicus, Stetates sturgeon A. stellatus and great sturgeon Huso huso) included 44 Persian sturgeon, 13 stellate sturgeon and 8 great sturgeon specimens. Fifty eggs were randomly collected from eac...

The embedding of test patterns into a sequential circuit is the main topic of this paper. Deterministic test patterns for the sequential circuit under test are chosen to be embedded into hybrid cellular automata (CA). Test identification and C.A synthesis are performed in parallel thus overcoming results achieved by embedding pre-computed vectors. The theory of sequential test generation under ...

Due to the increased applications of agents, Agent-oriented software becomes large and complex. To support systematic developments of such a software, Agent-oriented software development methodology needs to be developed. This paper focuses on modeling phase of agent-oriented software development. For the Agent-oriented software modeling, Agent Elicitation method, Intra and Inter Agent modeling...

The Stochastic Calculus of Looping Sequences (SCLS) is a recently proposed modelling language for the representation and simulation of biological systems behaviour. It has been designed with the aim of combining the simplicity of notation of rewrite systems with the advantage of compositionality. It also allows a rather simple and accurate description of biological membranes and their interacti...

We present a static analysis to infer the amount of data that a distributed system may transmit. The different locations of a distributed system communicate and coordinate their actions by posting tasks among them. A task is posted by building a message with the task name and the data on which such task has to be executed. When the task completes, the result can be retrieved by means of another...

Introduction In colonial America, throughout the Southeast region of the country, an invisible line once existed (Figure 1). With no identified boundaries, that line ran roughly in a southwest direction from the Chesapeake to a point in the Low Country. That line separated two politically, environmentally and socially disparate regions inhabited by culturally distinct yet similar groups of ensl...
