The tendon, connective fibrous tissue, mechanically responsible for the transmission of strength of muscles to bones, is a dynamic entity which, according to the constraints, restructures permanently and, thanks to various metabolic and mechanical changes. This review describes the histology, vascularization and innervation of the healthy tendon. In addition, the biomechanics and tendinous physiological responses, as well as the pathophysiology of tendinopathy are exposed. © 2014 Elsevier Masson SAS. [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.

Dans la plupart des familles de Cotonou, l’héritage est source de conflits. Qu’il s’agisse de frères et sœurs et de la gestion du patrimoine commun, d’un administrateur qui accapare l’ensemble des ressources, d’une veuve chassée par les enfants de ses coépouses, chaque famille fait l’objet d’une anecdote, de tensions latentes ou de conflits ouverts. Si certains n’hésitent pas à saisir les tribunaux, la justice constitue la plupart du temps le dernier recours. En cas de désaccord, quelles sont les démarches entreprises avant le tribunal? Il existe une série d’instances de médiation en matière familiale, depuis les sages de la famille ou du village, jusqu’aux tribunaux de conciliation ou aux ONG d’assistance juridique. Comment les héritiers choisissent-ils le forum auquel s’adresser ? Je m’intéresserai également au fonctionnement de ces institutions parajudiciaires, à la manière dont le droit y est mobilisé, dont les conflits y sont résolus ou renvoyés vers les tribunaux.

Measurements of the atmospheric HDO/H2O ratio help us to better understand the hydrological cycle and improve models to correctly simulate tropospheric humidity and therefore climate change. We present an updated version of the column-averaged HDO/H2O ratio dataset from the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY). The dataset is extended with two additional years, now covering 2003–2007, and is validated against co-located ground-based total column delta-D measurements from Fourier-Transform Spectrometers (FTS) of the Total Carbon Column Observing Network (TCCON) and the Network for the Detection of Atmospheric Composition Change (NDACC, produced within the framework of the MUSICA project). Even though the time overlap between the available data is not yet ideal, we determined a mean negative bias in SCIAMACHY delta-D of -35±30‰ compared to TCCON and -69±15‰ compared to MUSICA (the uncertainty indicating the station-to-station standard deviation). The bias shows a latitudinal dependency, being largest (about -60 to -80‰) at the highest latitudes and smallest (about -20 to -30‰) at the lowest latitudes. We have tested the impact of an offset correction to the SCIAMACHY HDO and H2O columns. This correction leads to a humidity and latitude dependent shift in delta-D and an improvement of the bias by 27 ‰, although it does not lead to an improved correlation with the FTS measurements nor to a strong reduction of the latitudinal dependency of the bias. The correction might be an improvement for dry, high-altitude areas, such as the Tibetan Plateau and the Andes region. For these areas, however, validation is currently impossible due to a lack of ground stations. The mean standard deviation of single-sounding SCIAMACHY–FTS differences is ~115 ‰, which is reduced by a factor ~2 when we consider monthly means. When we relax the strict matching of individual measurements and focus on the mean seasonalities using all available FTS data, we find that the correlation coefficients between SCIAMACHY and the FTS networks improve from 0.2 to 0.7–0.8. Certain ground stations show a clear asymmetry in delta-D during the transition from the dry to the wet season and back, which is also detected by SCIAMACHY. This asymmetry points to a transition in the source region temperature or location of the water vapor, and shows the added information that HDO/H2O measurements provide, if used in combination with variations in humidity.
