Le regain des délaissés, la permaculture sur le sol vivant

Nouvelles perspectives en sciences sociales (2022)

Serge Bernard

Pour commencer l’auteur s’interroge sur la catégorie sémantique « agriculture urbaine » : qu’y a-t-il en effet de commun entre toutes les multiples activités rangées sous ce générique ? Son approche repose au début sur l’esquisse d’une exploration de la notion au travers de plusieurs espaces comparés à l’échelle du global, pour arriver au local avec l’observation de petites parcelles travaillées en sol vivant par des permaculteurs avec qui l’auteur débat depuis des mois. La première partie dégage les premières lignes de la mise en débat de ce qui pourrait être un corpus de références ou valeurs communes, aussi bien à l’échelle planétaire, celle du « désordre global » (Coline Serreau, documentaire, 2010) qu’à la micro-échelle, celle « des solutions locales » (ibid.).Dans la deuxième partie, l’auteur analyse le sujet des espaces urbains délaissés, investis ou convoités par les permaculteurs urbains, qui s’entrecroisent avec les lieux de vie des délaissés sociaux. L’auteur croit y voir un possible retour de la forêt et le regain des lisières et marges. Il propose en synthèse l’idée que l’agriculture urbaine pourrait annoncer « une rupture anthropologique majeure » privilégiant la culture sur sol vivant et la fin du labour. Cet essai réflexif se nourrit d’échanges avec des permaculteurs urbains plus particulièrement proches de la pensée disruptive de Masanobu Fukuoka sur « l’agriculture sauvage » et le travail du « sol vivant », comme de celle des alter-architectes paysagistes et urbanistes qui ont théorisé les tiers-lieux dans la ville. L’auteur propose un autre regard des marges socio-spatiales dans la ville, spécialement des jardins de résistances à l’interstice de l’ombre des forêts et de la lumière crue et rase des défrichés.

Implementing indirect test of RF circuits without compromising test quality: a practical case study

Hassan El Badawi F. Azaı̈s Serge Bernard Mariane Comte Vincent Kerzérho

Cost reduction is a crucial step in testing AMS/RF circuits, and one way of achieving this is to implement an indirect test strategy. Although this strategy relaxes the requirements on test equipment, it still raises some accuracy concerns, which might compromise the test quality. In this work, we explore the benefit that can be brought by a two-tier adaptive test flow, in which only circuits with a sufficient prediction confidence level are evaluated by the indirect test while others are re-evaluated by specification-based test. A methodology is presented that permits to explore different tradeoffs between test quality and test cost and to make pertinent choices for the efficient implementation of such a test flow. The results are illustrated on a front-end RF circuit designed for WLAN applications and show that substantial test cost reduction can be achieved without compromising the test quality.

A novel protocol for rapid deployment of heart rate data storage tags in Atlantic bluefin tuna Thunnus thynnus reveals cardiac responses to temperature and feeding

Journal of Fish Biology (2023)

Tristan Rouyer Sylvain Bonhommeau Serge Bernard Vincent Kerzérho Olivier Derridj

The Atlantic bluefin tuna (ABFT) is a highly prized species of large pelagic fish. Studies of their environmental physiology may improve understanding and management of their populations, but this is difficult for mature adults because of their large size. Biologging of heart rate holds promise in investigating physiological responses to environmental conditions in free-swimming fishes but it is very challenging to anesthetize large ABFT for invasive surgery to place a tag in the body cavity near to the heart. We describe a novel method for rapid deployment of a commercially available heart-rate tag on ABFT, using an atraumatic trocar to implant it in the musculature associated with the cleithrum. We performed three sequential experiments to show that the tagging method (1) is consistently repeatable and reliable, (2) can be used successfully on commercial fishing boats and does not seem to affect fish survival, and (3) is effective for long-term deployments. In experiment 3, a tag logged heart rate over 80 days on a 60-kg ABFT held in a farm cage. The logged data showed that heart rate was sensitive to prevailing seasonal temperature and feeding events. At low temperatures, there were clear responses to feeding but these all disappeared above a threshold temperature of 25.5°C. Overall, the results show that our method is simple, rapid, and repeatable, and can be used for long-term experiments to investigate physiological responses by large ABFT to environmental conditions.

Which metrics to use for RF indirect test strategy?

Hassan El Badawi Mariane Comte F. Azaı̈s Vincent Kerzérho Serge Bernard

This paper aims at opening a discussion on the quality assessment of indirect test strategies in the context of analog and RF integrated circuit testing. Many parameters may influence the prediction efficiency of the indirect test model (choice and number of indirect parameters taken into account, learning algorithm used to build the model...). In order to evaluate the quality of a given model, several metrics can be evaluated, that reflect either the average prediction error, a global reliability or a misclassification rate. But what are the most pertinent metrics to reflect the level of confidence that can be expected from the indirect test to efficiently replace a traditional test based on RF measurements? Which metrics can lead to an informed choice of an indirect test strategy for its stability and predictive power? These considerations are investigated in this paper and illustrated in a practical case study.

Behavioural Responses of Common Dolphins Delphinus delphis to a Bio-Inspired Acoustic Device for Limiting Fishery By-Catch

Sustainability (2022)

Loïc Lehnhoff Hervé Glotin Serge Bernard Willy Dabin Yves Le Gall

By-catch is the most direct threat to marine mammals globally. Acoustic repellent devices (pingers) have been developed to reduce dolphin by-catch. However, mixed results regarding their efficiency have been reported. Here, we present a new bio-inspired acoustic beacon, emitting returning echoes from the echolocation clicks of a common dolphin ‘Delphinus delphis’ from a fishing net, to inform dolphins of its presence. Using surface visual observations and the automatic detection of echolocation clicks, buzzes, burst-pulses and whistles, we assessed wild dolphins’ behavioural responses during sequential experiments (i.e., before, during and after the beacon’s emission), with or without setting a net. When the device was activated, the mean number of echolocation clicks and whistling time of dolphins significantly increased by a factor of 2.46 and 3.38, respectively (p < 0.01). Visual surface observations showed attentive behaviours of dolphins, which kept a distance of several metres away from the emission source before calmly leaving. No differences were observed among sequences for buzzes/burst-pulses. Our results highlight that this prototype led common dolphins to echolocate more and communicate differently, and it would favour net detection. Complementary tests of the device during the fishing activities of professional fishermen should further contribute to assessment of its efficiency.
