Due their productivity, structural diversity, and potential to promote ecological, functional and morphological evolution, coral reefs have the highest species richness of fishes. As swimming is the primary form of locomotion and interaction their aquatic environment, small morphological variations can have profound implications on the fitness of fishes. The damselfish family, Pomacentridae, has inhabited coral reef ecosystems for more than 50 million years. As such, habitat preferences and behavior could significantly contribute to the evolution of the morphology of damselfish through the impacts of shape on locomotion. To test this hypothesis, we employed comparative morphometric analyses of fish shape and ecology. While body elongation represented the primary source of variation in locomotor system shape, results also showed a diverse suit of morphological combinations in between the morphological extremes. Results showed strong associations between behavior and habitat preferences, suggesting that behavior may constrain the shape of the locomotor system in damselfishes. Position in the water column show relation with the cephalic region and truck, behavior is related to the cephalic angle and the angle of insertion of the pectoral fin, while maximum depth is related to the caudal peduncle. Was found little relation between the caudal peduncle, the angle of pectoral fin attachment and the rest modules, therefore, this two modules may be the main responsible of swimming fitness in damselfishes. Finally, cephalic region is highly related to most modules, especially to trunk. This strong integration may be responsible of the limit morphological variation of damselfishes. [less ▲]

Large-scale epistasis studies can give new clues to system-level genetic mechanisms and a better understanding of the underlying biology of human complex disease traits. Though many novel methods have been proposed to carry out such studies, so far only a few of them have demonstrated replicable results. Here, we propose a minimal protocol for genome-wide association interaction (GWAI) analysis to identify gene–gene interactions from large-scale genomic data. The different steps of the developed protocol are discussed and motivated, and encompass interaction screening in a hypothesis-free and hypothesisdriven manner. In particular, we examine a wide range of aspects related to epistasis discovery in the context of complex traits in humans, hereby giving practical recommendations for data quality control, variant selection or prioritization strategies and analytic tools, replication and meta-analysis, biological validation of statistical findings and other related aspects. The minimal protocol provides guidelines and attention points for anyone involved in GWAI analysis and aims to enhance the biological relevance of GWAI findings. At the same time, the protocol improves a better assessment of strengths and weaknesses of published GWAI methodologies. [less ▲]

This paper considers a trajectory-based approach to determine control signals superimposed to those of existing controllers so as to enhance the damping of electromechanical oscillations. This approach is framed as a discrete-time, multi-step optimization problem which can be solved by model-based and/or by learning-based methods. This paper proposes to apply a model-free tree-based batch mode Reinforcement Learning (RL) algorithm to perform such a supplementary damping control based only on information collected from observed trajectories of the power system. This RL-based supplementary damping control scheme is first implemented on a single generator and then several possibilities are investigated for extending it to multiple generators. Simulations are carried out on a 16-generators medium size power system model, where also possible benefits of combining this RL-based control with Model Predictive Control (MPC) are assessed.

The aim of this study was to evaluate the physico-chemical stability of Belgian Blue beef packaged under high-oxygen atmosphere as a function of a previous aging technique (wet-aging in vacuum conditions vs. carcass-aging). Two muscles (longissimus dorsi vs. rectus femoris) were studied. After a seven-day wet- or carcass-aging step, muscle cuts from 4 Belgian Blue cows were vacuum packaged and stored at −1 °C for up to 28 days. Each 14 days, part of these samples was repackaged under modified atmosphere (70 % O2:30 % CO2), and stored during 7 days at +4 °C. The following parameters were evaluated: color, metmyoglobin %, metmyoglobin reducing activity, fat content, fatty acid profile, lipid oxidation, antioxidant enzyme activities and alpha-tocopherol content. The sensitivity of modified atmosphere repacked meat cuts to oxidation was influenced by the conditions of the previous aging period (wet > carcass conditions), muscle (rectus femoris > longissimus dorsi) and length of the vacuum storage.

Many countries and regions in Europe are nowadays setting up biobased economy strategies and action plans. For Belgium, the case of the Walloon region is discussed in this talk through a SWOT analysis. Even if a large part of the territory is covered by agricultural and forestry productions, the feedstock supply and availability are rather restricted. However, in order to stimulate the development of biorefineries in the Walloon region, it is important to support a reliable upstream supply chain. Therefore, several options are currently evaluated by the government, the industrial sectors and academic/research centers and presented herein through several pilot, R&D or industrial initiatives.
