The cerato-mandibular (c-md) ligament is a synapomorphy within Pomacentridae that creates a tight link between the lower jaws and the hyoid bars. However, this morphological trait has been secondarily lost in multiple lineages during evolution. A previous study revealed that the loss of this trait acted as a release of evolutionary constraints, leading to a cascade of morphological changes such elongated buccal jaws and a slender body. Ecomorphological interpretations suggested the loss of the c-md ligament has ultimately led to a new adaptive peak in zooplanktivory through an optimization of the ram feeding mode associated with a specialization in pelagic feeding. Here, we tested these hypotheses by comparing functional and diet diversity between damselfish species with and without the c-md ligament. Although species lacking the c-md ligament presented a conserved kinematic pattern resulting from high ram and low suction performances, our results did not support an optimization of the ram feeding mode. Indeed, some species with the c-md ligament showed the same or exceeded the ram performance of species without the c-md ligament. The species with the c-md ligament had a more diverse kinematic pattern exploring the entire ram-suction functional range in damselfishes. Finally, our results did not show any diet variations associated with the loss of the c-md ligament. Our study furthers the understanding of how a morphological trait has shaped, by its presence or absence, the ecomorpho-functional diversification of Pomacentridae. [less ▲]

The Specialized Master in Higher Education Pedagogy (Formasup) organized at the University of Liège (Belgium) aims at the professional development of teachers involved in Higher Education. The training programme gives participants the opportunity to make a full-scale SoTL study (from the implementation of a well-circumscribed course regulation to the assessment of its pedagogical effectiveness by means of the analysis of collected data) of one prominent aspect of their teaching practice. The process of trying out some new pedagogical approach and of discussing its effects on student learning has also to be reported in the form of a scientific paper (including a short review of the relevant pedagogical literature) and presented to a small audience of teacher colleagues. In order to meet the many requirements of such a complex task, each participant benefits from individualized pedagogical counselling. Besides a brief description of the Formasup context, the present contribution proposes brief case studies of three SoTL projects carried out in 2016. The case studies focus mainly on the dynamics of the interaction between teacher and pedagogical counsellor at each constitutive step of the SoTL project with the intention of making out the specificities of counselling applied to first time SoTL experience (time dedicated to and types of counselling activities in relation to the particularities of individual projects). The case studies are then integrated into a bigger picture drawing upon a larger number of counselling experiences over the last four years (from 2013 to 2016). On the basis of the main characteristics of 21 counselling experiences we propose a typology of teacher profiles according to their strategic approach to SoTL and the corresponding input of counselling.

Nicotiana tabacum BY-2 suspension cells have several advantages that make them suitable for the production of full-size monoclonal antibodies which can be purified directly from the culture medium. Carbohydrate characterization of an antibody (Lo-BM2) expressed in N. tabacum BY-2 cells showed that the purified Lo-BM2 displays N-glycan homogeneity with a high proportion (>70%) of the complex GnGnXF glycoform. The stable co-expression of a human β-1,4-galactosyltransferase targeted to different Golgi sub-compartments altered Lo-BM2N-glycosylation and resulted in the production of an antibody that exhibited either hybrid structures containing a low abundance of the plant epitopes (α-1,3-fucose and β-1,2-xylose), or a large amount of galactose-extended N-glycan structures. These results demonstrate the suitability of stable N-glycoengineered N. tabacum BY-2 cell lines for the production of human-like antibodies. © 2017, Springer International Publishing Switzerland.

This paper reports on a first attempt to apply the two first stages of the “Decoding the disciplines” framework (Pace, 2017) at the University of Liège (Belgium). In this context, 7 professors volunteered to reflect, through a structured process, upon “bottlenecks” in their courses, with the help of IFRES’ (Institute for Training and Research in Higher Education) pedagogical advisers. This pilot delivered contrasted observations: while participants granted value to their exposure to this approach, especially in terms of enhanced awareness of possible discrepancies between what experts and newcomers in the field might consider as obvious, none of them activated the possibility offered to tackle the identified bottlenecks, according to the systematic approach (stages 3-7) suggested by the framework. The paper presents the pedagogical setting, analyses the interviews of participants and the outcomes of the project, outlines explanations for its results, and shares some lessons learnt. [less ▲]

In an electrical system where decentralized and embedded productions are becoming more and more important, it is essential to ensure there is a good understanding of their behaviour at their operating limits. One the most important operating limits is when the system frequency approaches 50.2 Hz. At this frequency, following the old requirements, many existing European PV inverters have to be disconnected. In such situations, we will demonstrate that the variance of the frequency measurement taken at every PV inverter plays a key role. It will be demonstrated that this variance is actually a good thing from the system’s point of view as it allows for a gradual disconnection, leading to a controlled variation of the frequency.

Long-term monitoring of yellow- and glass eel stages were performed in upland areas (>300km from sea) in order (i) to quantify the decline of wild yellow eels entering in the Belgian Meuse from the Netherlands; (ii) to follow their upstream individual colonization; and (iii) to analyze the adaptation of young eels stocked as glass eels imported from UK. By monitoring a fish pass from 1992 to 2016, we quantified that the number of ascending eels has declined from n=5613 in 1992 to n=21 in 2016 (3.99%/year) and the mean length of eels has increased (4.1mm/year). During 6-years, upstream individual colonization of eels (2010-2015, n=1371) was followed using fixed RFIDtracking system. Few eels continued to migrate 4 years after tagging (<0.3%) and at >20km upstream (3.7%); and velocity of eels varied between individuals (0.012- 3.1km/day). In a 4-year (2013-2016) monitoring study of restocked glass eels using electrofishing and mobile RFID-tracking campaigns, we observed that eels grew rapidly in upland small brooks and recruitment was better in rivers with high carrying capacity (>15.8%, 2years post-stocking). Restocked eels dispersed in up- and downstream directions with behaviors including sedentary, nomadic and intermediate lifestyles. This suggests stocking as potential management measure to enhance local eel stocks. [less ▲]

In this work, we propose a simple yet effective solution to the problem of connectome inference in calcium imaging data. The proposed algorithm consists of two steps. First, processing the raw signals to detect neural peak activities. Second, inferring the degree of association between neurons from partial correlation statistics. This paper summarises the methodology that led us to win the Connectomics Challenge, proposes a simplified version of our method, and finally compares our results with respect to other inference methods.

Le portfolio est souvent investi par les étudiants en raison du lien étroit qu'il entretient avec l'évaluation. Idéalement pourtant, c'est tout un dispositif qu'il faudrait investir de cette même énergie, comprenant le lent processus de développement des compétences et les activités qui le soutiennent. Les étudiants sont peu familiers d'un développement graduel et intégré. La complexité de la compétence constitue une difficulté particulière, qui s'accommode mal des préparations "de dernière minute" et exige de placer un accent tout particulier sur le développement et la prise de conscience de ce développement.
