Smartphones, particularly Iphones, are equipped with high performance inertial units and absolute positioning systems that are traditionally used to measure user behavior. They are also very relevant instruments for researchers in animal behavior. In this work, a lambda cloud architecture and web services are developed to archive and process high-frequency data from the inertial center of an Iphone 4S using behavioral classification algorithms. In addition, a web interface for encoding behavior observed on videos allows to synchronize the observations with the measurements. [less ▲]

This seminar presents the efforts for implementing flow-chemistry in early chemistry curricula and academic research labs. We will illustrate the key concepts that are integrated in a series of lectures organized at the Department of Chemistry, University of Liège (Belgium). These lectures are complemented by workshops that successfully convey the subject matter at hand through practice in the lab. Some practical aspects for a successful curricular implementation will be thoroughly discussed. [less ▲]

Genetic loss-of-function studies in development, cancer and somatic cell reprogramming have suggested that the group of macroH2A histone variants might function through stabilizing the differentiated state by a yet unknown mechanism. Here, we present results demonstrating that macroH2A variants have a major function in maintaining nuclear organization and heterochromatin architecture. Specifically, we find that a substantial amount of macroH2A is associated with heterochromatic repeat sequences. We further identify macroH2A on sites of interstitial heterochromatin decorated by H3K9me3. Loss of macroH2A leads to major defects in nuclear organization including reduced nuclear circularity, disruption of nucleoli and a global loss of dense heterochromatin. Domains formed by repeat sequences when depleted of macroH2A are disorganized, expanded and fragmented and mildly re-expressed. On the molecular level we find that macroH2A is required for the interaction of repeat sequences with the nucleostructural protein Lamin B1. Taken together our results argue that a major function of macroH2A histone variants is to link nucleosome composition to higher order chromatin architecture. [less ▲]

The discovery of an increasing number of terrestrial planets around nearby stars marks the dawn of a new era in the exoplanet field: the characterization and understanding of their atmospheres. To make significant progress, it becomes clear that a large number of exoplanetary atmospheres have to be studied at various wavelengths. This is particularly relevant for identifying possible bio-signatures. In this poster, we present a concept of a space-based mid-infrared nulling spectrograph that can characterize a large number of exoplanetary atmospheres and provide key information on their size, surface temperature, and the presence of key molecules such as CO2, H2O, CH4 and O3. The proposed mission concept would be particularly suited to characterize Proxima Cen b. [less ▲]

Biomass gasification is interesting for the production of CO + H2 from wastes and catalysts are necessary for tars degradation. Catalysts were synthesized by the sol-gel process to develop γ-Al2O3 doped with 10%wt of nickel and 2 wt.% of a second dopant (Co, Cu, Fe, Mn, Mo). Before their adding in AlOOH sol, metallic dopants were complexed with (OCH3)3-Si-(CH2)3-NH-(CH2)2-NH2 (EDAS) to increase their dispersion by cogelation between EDAS and AlOOH clusters. These catalysts were tested at 650°C for toluene reforming. [less ▲]

One of the most problematic issues currently sweeping data protection debates concerns the right to erasure of one’s personal data. Also known as the right to be forgotten, its recognition has potentially significant implications for human-robot interactions. Starting from the European Union’s increasing focus on recognising and framing this right, this position paper maps the relevance of linking right to be forgotten and privacy-sensitive HRI-fields, identifying relevant research questions along the way.

Depuis le XIXème siècle qui a vu s’épanouir le concept de « peuple » sur des critères ethniques et linguistiques, les langues et les identités collectives sont souvent associées. Ce principe s’actualise notamment dans les identités régionales de Belgique. À l’heure où celles-ci prennent de plus en plus de poids dans une Belgique fédérale en voie de délitement, il convient de s’intéresser aux individus en situation d’allophonie au sein de ces régions unilingues. Ces individus, de plus en plus isolés par la définition dominante des identités subnationales belges, doivent presque nécessairement mettre en place des stratégies linguistiques et identitaires dans leurs interactions sociales. Afin d’étudier ces stratégies linguistiques et identitaires, notre thèse s’articule autour de deux questions de recherche contiguës. Tout d’abord, il s’agit d’expliciter comment des francophones vivant en Flandre et des néerlandophones vivant en Wallonie conceptualisent les/la langue(s) et les/ l’identité(s). Après avoir défini les modalités de conception et les différents contenus de ces concepts, l’analyse se concentre sur les stratégies linguistiques et identitaires que ces informateurs disent mettre en place en situation d’interaction. En convoquant la sociolinguistique, la linguistique cognitive, la psychologie sociale et la sociologie de l’identité, cette thèse se veut interdisciplinaire afin de mettre en lumière au mieux les liens entre langue(s) et identité(s) au sein du processus d’identification de l’individu.

Hedgerows and woody strips have been used to enclose fields but declined due to the loss of a direct economic value, abandonment of traditional management techniques and agricultural intensification. Nowadays, shrubs and trees on pastures are promoted again through environment-friendly policies and the interest in using them as forage for ruminant increases in both temperate and tropical ecosystems. Woody plants on farmland could yield a wide range of ecosystem services and provide benefits for farmers and their animals such as forage supply to livestock, animal protection against severe weather and reduced parasitic infestation. Moreover, shifts in digestive physiology can be observed that will in turn affect the welfare and the performances of the animal and the production system as a whole. Therefore, in order to contribute to the development of sustainable systems using shrubs and trees as a feed component in its full right, the aim of this work was to investigate the influence of trees and shrubs on the behaviour of grazing cattle and their selectivity towards woody species, and to determine the changes induced by temperate and tropical shrub and tree species on rumen fermentation. Firstly, the behaviour of grazing dairy heifers was recorded during the whole grazing season as well as their selectivity towards temperate woody species in a hedge. It was concluded that having access to a hedge influenced the behaviour of grazing cattle, as the animals ingested woody plants in each season but mostly when the available pasture biomass was lower. The most selected species were Carpinus betulus, Corylus avellana, Cornus sanguinea and Crataegus monogyna. Secondly, the chemical composition, in vitro rumen fermentation profile and protein precipitation capacity (PPC) of the temperate shrub and tree species were measured. The analyses showed that Fraxinus excelsior presented the most interesting profile in terms of chemical composition and in vitro fermentation production. Among the preferred species, C. monogyna and C. avellana produced lower CH4 and the latest had the highest PPC. Thirdly, three newly-developed cultivars of the tropical Desmanthus genus were studied for their effects on in vitro rumen fermentation including potential to reduce CH4. Desmanthus leptophyllus and D. bicornutus had the highest anti-methanogenic potential, and D. bicornutus was more digestible. In conclusion, both temperate and tropical shrub and tree fodder are promising to supplement cattle with good quality forage. Cattle can browse woody species voluntarily, however, further investigations are needed to provide relevant practical recommendations on how to manage this resource adequately in order to balance intake by the animal and regrowth capacity of the plant. The impact of management strategies relying on cutting and preservation should also be assessed. Moreover, benefits of shrubs and trees on pastures beyond the animal feeding and nutrition are still poorly characterized while, in an agroecological perspective, they can contribute to a significant improvement of the sustainability of ruminant production systems.
