Studying the larval dispersal of bottom-dwelling species is necessary to understand their population dynamics and optimize their management. The black-lip pearl oyster (Pinctada margaritifera) is cultured extensively to produce black pearls, especially in French Polynesia's atoll lagoons. This aquaculture relies on spat collection, a process that can be optimized by understanding which factors ...

We apply a method proposed recently for estimat ing entropie s of sy mbol sequences to two ensembles of binary seq uences obtained from dynamical sys tems. T he first is th e ensemble of (0,1)sequences in a generating part it ion of the Henon map ; th e second is th e ensemb le of spat ial st rings in cellular automaton 22 in t he stat ist ica lly stat ionary state. In both cases , t he ent rop...

Two episodes of mortality of cultured carpet shell clams (Ruditapes decussatus) associated with bacterial infections were recorded during 2001 and 2002 in a commercial hatchery located in Spain. Vibrio alginolyticus was isolated as the primary organism from moribund clam larvae that were obtained during the two separate events. Vibrio splendidus biovar II, in addition to V. alginolyticus, was i...

Signalized intersections can increase the vehicle stops and consequently energy consumption by forcing stop-and-go dynamics on vehicles. Eco-driving with help of connectivity is a solution that could avoid multiple improve efficiency. In this paper, an eco-driving framework developed, which finds energy-efficient speed profile both up- downstream signalized intersection in free-flow situations ...

In the Einstein stat ic Universe the gravit ational self-attract ion of homogeneously dist ribut ed matter and the cosmological repulsion implied by the cosmological constant balance each other. Eddington [1] showed in 1930 that this balance is unstable: any departure from it will cause the Universe to either expand or collapse away from the init ial state. The perturbed solut ions are the Frie...

The mangrove cockle Anadara grandis (Broderip and Sowerby, 1829) is a potential candidate for aquaculture and for bioremediation of aquaculture effluents in the tropical and subtropical coastal areas of the eastern Pacific Ocean. Laboratory-produced spat are available, but there is no information on their responses to the range of environmental conditions to which they might be subject during t...
