On-chip Generation of Sine-wave Summing Digital Signals: an Analytic Study Considering Implementation Constraints
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)

In the context of biosensor as much as Built-In-Self Test (BIST), on-chip sine-wave signal generation is a recurring research topic. Considering the implementation constraints, it implies a trade-off between the amount of resources and the signal quality. An attractive solution consists in combining several digital signals to build this analog sine-wave. The objective of this paper is to give an analytic study of various potential digital-based solutions. Thanks to this study, we prove that the technique consisting in setting the phase shifts and various amplitude values of the square-wave signals is the most efficient approach. This study allows the selection of the optimal square-wave signal parameters to cancel low-order harmonics of the generated...

Effects of extraction method and storage of dry tissue on marine lipids and fatty acids

Various protocols are currently used to study marine lipids, but there is a growing interest in working on dry samples that are easier to transport. However, reference protocols are still lacking for dry samples. In order to make recommendations on this use, lipid classes and fatty acids (FA) obtained from six analytical protocols using two different tissue states (dry vs wet) and three extraction methods (automat vs manual potter vs leaving the solvent to work on tissue) were compared. Three dry storage modes of tissue (freezer vs gas nitrogen vs dry room) during one and three months were also compared. These comparisons were made on seven marine species with different lipid profiles, including fishes, crustaceans and mollusks. Lipid classes and FA...

Tagging Atlantic bluefin tuna from a farming cage: An attempt to reduce handling times for large scale deployments
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)

Our knowledge on the biology and ecology of marine species have improved greatly through the use of archival tags by enabling the collection on information from individual in the wild. This is specifically true for large pelagic species such as the Atlantic Bluefin tuna (ABFT, Thunnus thynnus) where, for the first time, it has been possible to confirm through fisheries-independent data, migration patterns, reproductive and feeding behaviours and habitat use. However, large-scale tagging experiments that would enable researchers to tackle group behaviour are difficult to set up. On the one hand, the impact of the actual tagging operation should be as minimal as possible to avoid any change in behaviour of the fish which could influence tag data analyses. On...

Analytical study of on-chip generations of analog sine-wave based on combined digital signals
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: David-grignot, Stephane; Lamlih, Achraf; Kerzerho, Vincent; Azaıs, Florence; Soulier, Fabien; Bernard, Serge; Rouyer, Tristan; Bonhommeau, Sylvain.
On-chip sine-wave signal generation is widely covered by literature for Built-In-Self Test (BIST) or biosensor applications. The objective is to generate pure and robust sinewave signal with minimal hardware resources. An attractive solution consists in combining several digital signals to built this analog sine-wave. The objective of this paper is to give an analytical study of various potential solutions based on digitalbased approaches. Thanks to this study, we prove that technique consisting in setting the phase shifts and various amplitude values of the square-wave signals is the most efficient approach. Moreover, this study allows the selection of the best solution in terms of parameters of the square-wave signals to cancel loworder harmonics of the...

Tagging Atlantic bluefin tuna from a Mediterranean spawning ground using a purse seiner
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Rouyer, Tristan; Bonhommeau, Sylvain; Giordano, Nicolas; Giordano, François; Ellul, Saviour; Ellul, Giovanni; Deguara, Simeon; Wendling, Bertrand; Bernard, Serge; Kerzerho, Vincent.
Atlantic bluefin tuna, Thunnus thynnus, is as an emblematic and commercially valuable large pelagic species. In the past ten years, the purse seine fishery in the Mediterranean represents more than 50 % of the catch. Nowadays, purse seines target large fish and operate during the spawning season in the spawning grounds. Electronic tagging has shed a considerable amount of light on the ecology and behaviour of bluefin tuna over the past twenty years. However, such technique has rarely been applied on large bluefin tunas caught by the Mediterranean purse seine fishery despite its major importance. The logistical constraints related to this specific fishery, combined with the timing of migration of the fish and the requirements related to the handling of big...
