Could Ghosts Explain the Quantum World?

Witten and Veneziano gave an important role for topological susceptibility ?. After their work, it was linked with ?’ mass, solving the U(1)A problem using the called Veneziano ghost K? that is an unphysical massless pole. Though, K? is gauge variant and non-perturbative. In an recent paper, Kharzeev and Levin try to establish a relationship between Veneziano ghost and color confinement. However, Dudal and Guimaraes showed that the result of Kharzeev and Levin breaks the perturbative BRST symmetry.

Can we color blue products naturally? Production of the natural blue dye phycocyanin by the cyanoba

Synthetic dyes are mainly used to color food, textiles and cosmetics, but their negative effect on human health and environment has led consumers’ attention to natural ones. Although it is easy to find natural alternatives for most of the colors, blue is a rare color in nature, making its substitution more challenging. Arthrospira (Spirulina) is a cyanobacterium that can be used as a source of a natural blue dye, phycocyanin. Phycocyanin is already used as a food colorant, but there is an increasing demand to broaden the scope of its applications to other industries too.

Plant sterols: Can we make fat rich food healthy?

Phytosterols are plant based compounds with chemical structures similar to cholesterol and have nutritionally beneficial properties, more specifically a blood cholesterol lowering effect. In order to increase their lipid solubility and thus facilitate their incorporation into fat containing food products, phytosterols are esterified with fatty acids (FA) to obtain phytosterol esters. Addition of PE to fat (containing products) will undoubtedly influence the crystallization properties and in food industry this will lead to problems occurring during the production process or with the macroscopic properties of the end product. But despite this, Scientific publications on the influence of PE addition on the crystallization of edible fats are very much lacking and industrial practice relies on a trial and error approach. The objective of this doctoral research is thus to thoroughly study the influence of the addition of phytosterol esters on the crystallization behavior of edible fats both at the level of the equilibrium and at the level of the crystallization kinetics. The influence on primary crystallization, polymorphism, network formation and obtained macroscopic properties will be investigated. More specifically, the effect of phytosterol ester concentration, type of fatty acid esterified, type of phytosterol, type of ‘host’ fat to which the phytosterol esters are added and degree of undercooling of the host fat will be investigated.

Genotype-dependent gut microbiota drives resistance to toxic cyanobacteria in the water flea Daphnia

Eutrophication and climate change have caused a widespread occurrence of cyanobacterial harmful algal blooms (cyanoHABs) in lakes, ponds and reservoirs worldwide1,2. Due to the release of powerful toxins in the water, CyanoHABs pose severe threats on livestock and human health, causing diseases from gastrointestinal symptoms to liver cancer3. In aquatic ecosystems, cyanoHABs have a strong negative impact on zooplankton grazers, and through the food web, disrupt the whole freshwater community4. Deciphering the mechanisms underlying resistance to toxic cyanobacteria in these grazers is thus essential to predict how cyanoHABs can be prevented or controlled5. In the freshwater crustacean Daphnia, resistance is influenced by prior exposure to cyanobacteria6,7 and genotype8,9, but the underlying mechanisms remain unclear. Through gut microbiota transplants, we here show that the gut microbiota plays a crucial role, and might mediate both genetic adaptation and acclimatization to cyanoHABs. Microbiota from resistant genotypes conferred a higher resistance to recipient Daphnia than microbiota from susceptible genotypes. Resistance to cyanobacteria in recipient Daphnia was not affected by the recipient genotype, but was strongly impacted by the donor genotype. This suggests that the Daphnia genotype acts indirectly on resistance to cyanobacteria, by shaping the gut microbiota. In addition, resistance was higher when donors were previously fed cyanobacteria, suggesting that gut microbiota responded to become more efficient in dealing with cyanobacteria after prior exposure. Next generation sequencing of 16S rDNA shows that resistance is associated with changes in microbiota structure: cyanobacterial exposure favored bacterial taxa involved in digestion of cyanobacterial cells10 and detoxification of cyanobacterial toxins11. Our results provide evidence that resistance to toxic cyanobacteria in Daphnia is driven by the gut microbiota, which might thus be an important mediator of the genetic mosaic of coevolution between toxic cyanobacteria and their grazers, and a key determinant of how freshwater ecosystems respond to climate warming.

Review of Single-Subject Experimental Design (SSED) Meta-analyses

Because of the growing number of SSED meta-analyses and the advances in (meta)analytical approaches and methods, our findings of a systematic review of the literature between 1985 and 2015 indicate a large variety in procedures that are applied and the lack of consensus about the most appropriate methods, both for expressing the size of the effect in primary studies and for synthesizing these over studies. Despite the methodological advancements in SSED (meta-) analysis, a considerable number of meta-analyses still apply the simple methods instead of the more advanced methods. Some changes have taken place during 3 last decades in employing various effect size measures and applying different techniques for combining the results across primary studies, however the evolution in the use of advanced methods is rather slow.

A unique antibody screening platform based on Digital Microfluidics

Acquired Thrombotic Thrombocytopenic Purpura (aTTP) is a rare microangiopathic disorder caused by the presence of anti-ADAMTS13 autoantibodies that without proper diagnosis and treatment leads to early patients’ dead. Rapid and sensitive assays are needed to improve aTTP diagnosis. This can be achieved by providing the antibody repertoire of each patient. Digital microfluidic (DMF) technology is an innovative technique where flowing of cells is digitally controlled and enables the development of automatic platforms. The aim of this project is to develop a microfluidic platform using DMF technology to detect single B cells expressing anti-ADAMTS13 and to identify the antibody repertoire of aTTP patients.

Incoming rear traffic detection on a smart bike

This project proposes research and development of a vision system, placed on a bicycle, which can automatically detect rear traffic and alert the cyclist of an incoming vehicle. In this way the cyclist doesn’t need to look behind him while cycling, which improves stability and safety. The vision algorithms can distinguish between incoming, retreating and parked vehicles. The algorithms are based on optical flow and the Lucas-Kanade algorithm, hence no training set is needed. A proof-of-concept was build using an Odroid XU4 microprocessor platform with a steer-mounted display. Subsequently, some field test were taken using the prototype, resulting in a combined accuracy of 77%.

Real obligations at the edge between contracts and property

Some obligations are tied to a good or, more precisely, to a property right. Article 698 of the Civil Code (both Belgian and French), for instance, provides that the owner of a servient land can assume the obligation to execute works necessary for the servitude. Future owners of the servient land are automatically bound by this obligation. While the existence of obligations tied to aproperty right or ‘real obligations’ is accepted, uncertainty exists asto their regime, nature and foundation. Real obligations are said to ‘run with the land’: whoever holds the land will become the debtor of this obligation. The obligations are thus transferred together with the property right. However, will the former debtor of theobligation be freed by the transfer of the property right? And what happens when a current debtor renounces his property right? Is he then freed from his obligation, even from due obligations? Not only the regime of real obligations is unclear, so is their nature. Real obligations might actually be personal obligations as they consist of a duty in faciendo. Their regime however, seems to induce that they are a part of the property right. An inquiry into the nature, regime and foundation of real obligations is necessary. The research will not only be conducted in regard of Belgian law, but also in regard of French, Dutch and Scots law. The statutes in the latter two legal systems moreover recognise autonomous real obligations, subject to party autonomy.

How to manage a patient with acquired TTP? Identification of new prognostic biomarkers

Acquired TTP is a chronic disease which manifests in episodes where affected persons get very sick and need to be hospitalised. This condition limits their life-comfort as -at least theoretically - they always need to be prepared for such an episode. The goal of my research project is to identify biomarkers which, according to patient antibodies, predict when aTTP episode will occur, so the patients can prevent the relapse and their life-comfort increases. The biomarkers used to predict patients prognosis are some “special kind of antibodies” (anti-ADAMTS13 autoantibodies). The aim is to have an overview on the immunoprofile of aTTP patients based on these antibodies and afterwards to discriminate among different immunoprofiles linked to a different disease outcome.

Anatomical adaptations to conflicting functional demands in the primate thumb

The development of bipedal locomotion marks the point in human evolution that freed our hands, which in turn resulted in unprecedented dexterity. This enhancement is largely due to the high mobility of the thumb, allowing modern humans to execute precise manual activities. Despite the importance to human evolution, knowledge on form-function relations of the thumb remains lacking. By comparing the anatomy and biomechanics of the TMC joint in species utilizing different locomotor strategies (bonobo, gibbon and baboon) we seek to contribute to the understanding of adaptations in primate thumb anatomy.

Ethnic and religious identity negotiations on Instagram

This study explores the way ethnic and religious identities are constructed via social media, in particular through lifestyle representations on Instagram. The emerging transnational Mipster movement, which has spurred debate in the Muslim community about modesty, is taken as a starting point for our focusgroups with Turkish-Flemish girls (N=26). The results confirm the hybrid identities of minority youth and a strong preference for Instagram (over Google and Facebook) for lifestyle and clothing inspiration. Friends, brands and influential bloggers are followed. Although a modest clothing style as found in the Arab world is aspired by most girls, the Flemish social context and retail market often prevent them from wearing the modest fashion they adore. Mipsters, and 'modern Turkish women', are mostly followed by younger teens and are both rejected and considered a first step towards a more religious and modest lifestyle. As a result, European minority blogsters are most widely followed and approved, offering girls lifestyle choices (like #OOTDs) that are within reach and bridge diverging norms within society. Influential bloggers on Instagram can become key agenda setters and endorsers for brands that tailor to the needs and values of the growing muslim consumer market.

Effectiveness of interactive and adaptive learning support for online educational videos.

Nowadays, the Internet offers numerous kinds of online videos, among which educational ones (e.g. MOOCs, flipped classroom, TED talks, but also numerous channels on YouTube). Those videos enable people to get instruction in a multitude of different subjects by themselves. This phenomenon usually involves more frequent contact with foreign languages via audiovisual input. Therefore, the easy availability of foreign online educational videos also enlarges the need to learn languages in order to understand videos’ content. Indeed, videos have for long been used to improve second language (L2) listening comprehension and vocabulary acquisition. However, learning a language through video is not an easy thing to do. One reason for that is that people do not pay enough attention, another reason is that people using this audiovisual input have different needs and backgrounds. A lot of researchers have already investigated the effects of different input enhancement techniques/learning supports in videos, such as full captioning in L1 or L2, glossaries, and keywords captioning, on learners’ vocabulary acquisition and listening comprehension. However, the results are far from univocal. It is still not clear which language should best be used in subtitles (L1, L2), whether glossaries in full captioning can help vocabulary acquisition and whether keywords captioning are more useful than full captioning. This PhD project will thus investigate the effectiveness (i.e. perceived usefulness, actual use and learning gains) of different input enhancement techniques. It focuses on investigating which language is most useful in subtitles for both content comprehension and vocabulary acquisition and whether full captioning with highlighted target words (FCHT) with(out) glossaries would be most effective than keywords captioning (KC) with(out) glossaries. Moreover, it will also study how leaners’ attention can be enhanced and directed towards vocabulary. Therefore, this project will not only make use of offline measures (e.g. vocabulary and listening comprehension tests), but also of online measures (e.g. eye-tracker, log files). Next to that, new input enhancement techniques/learning supports, such as pop-up quiz, will be set up in videos to complement the other ones and to check whether they help learners understand and learn. Finally, this project will focus on the adaptivity of these learning supports according to learners’ needs, attitudes and individual factors.

Time to get real! Online learning environments to deal with a complex world.

According to the European Commission, a challenge in education is to prepare individuals for varied and unpredictable career paths in the future (Rethinking education, 2012). Learning environments should focus on domain-specific and domain-general competencies (e.g., entrepreneurship, foreign language acquisition, and critical thinking) to deal with ill-structured problems in the learning and workplace context. The present PhD project will focus on online learning environments for complex learning. More particularly, it will focus on (1) the design of the learning environments (e.g., instructional design principles), (2) learner characteristics (e.g., prior knowledge), and (3) the interaction between the former two aspects (e.g., tool use) to explain differences in complex learning acquisition, on the one hand, and to develop adaptive, more effective online learning environments for complex learning, on the other hand.

Software Strategies to Counter Soft-Errors in Programmable Embedded Systems

Programmable Embedded Systems form the cornerstone for the rising challenges in the next industrial revolution of cyber physical systems where everything gets connected, data is interchanged and decisions are made by programmable controllers. Application areas are mobility, manufacturing, smart energy consumers, health and elderly care. This implies a more frequent use of such systems in applications requiring high reliability in harsh environments. The rise in electronics significantly increases the probability of all kinds of disturbances, which is amplified by the decreasing intrinsic immunity. An important innovation in this research project, next to the optimization of the software design and automated test procedures, is the inclusion of software solution in the system, making it fault resistance or tolerant, which leads to a cost efficient solution in many situations. Such software solution is rarely applied, mainly because they are not widely known and need further research for effective implementation. A key objective of this research is to design and produce better and more reliable electronics with a lower development cost and a shorter time-to-market.

We aim to investigate the interplay between algal biology and flocculation to understand the fundamental mechanisms behind microalgal flocculation. Cell properties such as size, surface charge/density, and chemical composition of cell-associated organic matter differ between species, strains and culture conditions and this affects flocculation. We aim to understand these interactions and we want to link this to flocculation as a harvesting process.

Can we use water flea Daphnia as a novel model to study cancer-related processes like hypoxia-induce

Cancer cells have developed diverse mechanisms to escape from the primary tumor locus and move into other tissues. One of these escape techniques is called epithelial-to-mesenchymal-transition or shortly EMT. EMT is a reversible process in which cancer cells loose their epithelial characteristics (polarity and non-migratory) and become mobile mesenchymal cells. This mechanism can be triggered by several stimuli e.g. a reduced level of oxygen in the tumor microenvironment or hypoxia. Most data on EMT are based on in vitro experiments. The exact EMT underpinnings in multicellular organisms are still a matter of debate as complex animal models for EMT are lacking. Here, we suggest invertebrate Daphnia magna as a novel model system in the study of hypoxia-induced EMT.

From parasite to ecosystem - The potential of Daphnia-parasite coevolution to affect fundamental eco

Despite the increasing consensus that parasites can have pronounced ecosystem level effects, their role in ecosystem functioning is still largely understudied. This research project aims at obtaining insights in the potential of host-parasite coevolution as an important evolutionary process underlying eco-coevolutionary dynamics. We aim to study how this eco-coevolutionary dynamics affect fundamental ecosystem functions, more in particular primary productivity and nutrient recycling in freshwater ecosystems. We focus on Daphnia magna, a keystone species in pelagic water systems, and multiple parasite species. We will (1) quantify the degree to which parasites may drive these ecosystem processes, (2) unravel the particular role of ecological and coevolutionary dynamics and their interaction, and (3) develop predictive mathematical models to explore possible scenarios for eco-coevolutionary dynamics.

Make Tests Deterministic Again

An Actor reacts upon receiving concurrent messages. However when receiving multiple messages the order is not guaranteed. If there is a dependency upon the order in which the messages are received, this might lead to unexpected behavior, which is difficult to test. The Deterministic State Space Exploration (DSSE) algorithm allows to extract information of a single test run and discover new paths in a deterministic way. We developed a tool, the Marshal actor, which intercepts messages sent by Actors and resends these to explore all paths in the state space of a test generated by the DSSE algorithm

Composition and functionality of the Daphnia magna microbiome

The animal body forms a habitat for a diverse and dynamic symbiotic microbial community, also called the microbiome. This microbiome can significantly influence the health and fitness of its host by helping with digestion, acquisition of nutrients and protection against pathogens and toxic substances. Both the composition of the microbiome and its relationship with the host is often context dependent.The net effect of the microbiome on host fitness can thus be positive (mutualistic), neutral (commensal) or negative (parasitic), dependent on environmental circumstances. We use the waterflea Daphnia magna as an experimental model system for investigating the context dependency of host-microbiota interactions.

On the largest multilinear singular values of higher-order tensors

Let $\sigma_n$ denote the largest mode-$n$ multilinear singular value of an $I_1\times\dots \times I_N$ tensor $\mathcal T$. We prove that $$ \sigma_1^2+\dots+\sigma_{n-1}^2+\sigma_{n+1}^2+\dots+\sigma_{N}^2\leq (N-2)\|\mathcal T\|^2 + \sigma_n^2,\quad n=1,\dots,N. $$ We also show that at least for third-order cubic tensors the inverse problem always has a solution. Namely, for each $\sigma_1$, $\sigma_2$ and $\sigma_3$ that satisfy \begin{equation*} \sigma_1^2+\sigma_2^2\leq \|\mathcal T\|^2 + \sigma_3^2,\quad \sigma_1^2+\sigma_3^2\leq \|\mathcal T\|^2 + \sigma_2^2,\quad \sigma_2^2+\sigma_3^2\leq \|\mathcal T\|^2 + \sigma_1^2,\\ \end{equation*}% and the trivial inequalities $\sigma_1\geq \frac{1}{\sqrt{n}}\|\mathcal T\|$, $\sigma_2\geq \frac{1}{\sqrt{n}}\|\mathcal T\|$, $\sigma_3\geq \frac{1}{\sqrt{n}}\|\mathcal T\|$, there always exists an $n\times n\times n$ tensor whose largest multilinear singular values are equal to $\sigma_1$, $\sigma_2$ and $\sigma_3$. We also show that if the equality $\sigma_1^2+\sigma_2^2= \|\mathcal T\|^2 + \sigma_3^2$ holds, then $\mathcal T$ is necessarily equal to a sum of multilinear rank-$(L_1,1,L_1)$ and multilinear rank-$(1,L_2,L_2)$ tensors and we give a complete description of all its multilinear singular values. We establish a connection with honeycombs and eigenvalues of the sum of two Hermitian matrices. This seems to give at least a partial explanation of why results on the joint distribution of multilinear singular values are scarce.

Keeping them at (near?) distance? Education the so-called "évolués" in the former Belgian Congo dur

Thesis: évolués were seen as unequal partners; they were treated as big children [cf. the distribution of Cartes de mérite civique(1948) and the system of Immatriculation(1952)], who had to be grateful for the gradual development of their personality. Such an approach –quantitatively as well as qualitatively–was not able to shape the mental space for autonomy and independence. On the contrary, it contributed to continue, even in the postcolonial period, the patronizing tone of the leaders. They took over the spatial, institutional, social and cultural structures of colonialism •Method: reading everyday reality(“normality”) through the propaganda (“normativity”) of the iconographic sources (films/photos); confrontation with interviews and egodocuments(such as biographic and autobiographic material) •Expected results: a better understanding of the processes of cultural hibridity by describing and analyzing the effects of colonial education

Access-To-Medicines Supply Chain Design: A Stakeholder Framework

Many rigorous models have been developed to support the design of humanitarian supply chains. Supply chains supportive of Access to Medicines (ATM), like vaccine supply chains impose considerable additional challenges on this design process. We embed these models in a broader stakeholder based framework. This will substantially enhance the societal and human impact of the ATM supply chain service delivery. This broader base of stakeholders will deliver a balanced set of Key Performance Indicators, against which the new design options or scenarios will be evaluated. These scenarios will be the outcome of an iterative design and modelling process moderated by a group of key stakeholders. Subsequently, a multi-criteria ranking method will reveal a shortlist of championing scenarios. Finally, a group decision process will decide on the final supply chain design choice. Moreover, the acceptance and buy-in of the (re)designed supply chain will be much more evident for all stakeholders involved. The main purpose of this research is to present a general framework for ATM supply chain design which constitutes a stakeholder’s framework encapsulating a rigorous modelling approach.

Theoretical & Numerical Study of Contact Nonlinearity

Interaction of ultrasonic waves with imperfect interfaces, and, in particular, with interfaces between rough surfaces in contact will result in the generation of nonlinear phenomena, mainly caused by nonlinear clapping and stick-slip behavior. The occurrence of contact nonlinearity is extremely interesting as it can be considered as a fingerprint of crack-like discontinuities. In this research, a theoretical study is performed and realistic numerical models are developed in order to obtain a better understanding of contact nonlinearity, and to explore its potential to offer new tools for non-destructive testing and evaluation of materials.

Harvest yield estimation of fruit tree orchards with an autonomous unmanned helicopter (drone)

This is a doctoral research project in which an autonomous rotary UAV is designed, constructed and flight tested for close-range inspection of fruit orchards and vineyards by flying autonomously through the narrow corridors in between trees. A special configuration combining large lift and small control rotors allows the vehicle to maximally utilize the limited width of the corridors while attaining longer endurance and/or carrying more payload. The autonomous control is performed by intelligently combining data from several sensors to safely navigate the fruit tree corridors. Sideward looking cameras capture the individual fruit and advanced image processing algorithms estimate the harvest yield.

Human bio-artificial muscle

The main goal of this project is the development of in vitro human skeletal muscle tissue. There are several applications for these organoids such as replacement of damaged or lost skeletal muscle tissue and expanding fundamental knowledge of tissue engineering. Existing techniques involve culturing and differentiation of myogenic (stem) cells on natural or synthetic scaffolds. In our lab, human muscle progenitor cells are engineered in a 3D hydroggel and grown in a custom-made mold with 2 attachment points, serving as artificial tendons. The resulting muscle organoids consist of aligned multinucleated myofibers and can be electrically and mechanically stimulated. However, the size of the muscle constructs is limited, due to the lack of vasculature which is needed for proper tissue perfusion. In this project, we evaluate strategies for vasculogenesis: the formation of blood vessel networks in vitro. Therefore muscle progenitor cells are co-cultured with endothelial cells to form vascularized bio-artificial muscle.

Democracy and education

My current principal research interets are concerned with the relationship between democracy and education, focussing on two themes. The first theme is on the spread of flamingant, anti-modern ideas. A second theme involves the study of historical processes of naturalization and integration.
