We present the notion of a filtered bundle as a generalization of a graded bundle. In particular, we weaken the necessity of the transformation laws for local coordinates to exactly respect the weight of the coordinates by allowing more general polynomial transformation laws. The key examples of such bundles include affine bundles and various jet bundles, both of which play fundamental roles in geometric mechanics and classical field theory. We also present the notion of double filtered bundles which provide natural generalizations of double vector bundles and double affine bundles. Furthermore, we show that the linearization of a filtered bundle — which can be seen as a partial polarization of the admissible changes of local coordinates — is well defined. [less ▲]

Genetic epilepsies are caused by mutations in a range of different genes, many of them encoding ion channels, receptors or transporters. While the number of detected variants and genes increased dramatically in the recent years, pleiotropic effects have also been recognized, revealing that clinical syndromes with various degrees of severity arise from a single gene, a single mutation, or from different mutations showing similar functional defects. Accordingly, several genes coding for GABAA receptor subunits have been linked to a spectrum of benign to severe epileptic disorders and it was shown that a loss of function presents the major correlated pathomechanism. Here, we identified six variants in GABRA3 encoding the α3-subunit of the GABAA receptor. This gene is located on chromosome Xq28 and has not been previously associated with human disease. Five missense variants and one microduplication were detected in four families and two sporadic cases presenting with a range of epileptic seizure types, a varying degree of intellectual disability and developmental delay, sometimes with dysmorphic features or nystagmus. The variants co-segregated mostly but not completely with the phenotype in the families, indicating in some cases incomplete penetrance, involvement of other genes, or presence of phenocopies. Overall, males were more severely affected and there were three asymptomatic female mutation carriers compared to only one male without a clinical phenotype. X-chromosome inactivation studies could not explain the phenotypic variability in females. Three detected missense variants are localized in the extracellular GABA-binding NH2-terminus, one in the M2-M3 linker and one in the M4 transmembrane segment of the α3-subunit. Functional studies in Xenopus laevis oocytes revealed a variable but significant reduction of GABA-evoked anion currents for all mutants compared to wild-type receptors. The degree of current reduction correlated partially with the phenotype. The microduplication disrupted GABRA3 expression in fibroblasts of the affected patient. In summary, our results reveal that rare loss-of-function variants in GABRA3 increase the risk for a varying combination of epilepsy, intellectual disability/developmental delay and dysmorphic features, presenting in some pedigrees with an X-linked inheritance pattern.

Many cross-border mergers do take place in Luxembourg. Most practical difficulties in implementing the new regime were solved in the first months/years following the transposal of the Cross-Border Mergers directive. As a matter of fact most of the cross-border mergers taking place in Luxembourg are of a rather uncomplicated kind as they are often intra-group mergers, between companies with no or very few employees and furthermore in a vast majority of cases between a parent company and its 100% subsidiary. In the most recent practice however, the following questions/issues were raised : - the directive only addresses mergers. Other restructurings such as divisions, transfers of assets, of a branch of activity or of the universality of the company’s assets are not covered by the directive and this even though they can likewise take place across the borders and can be difficult to carry out in the absence of some harmonized regime; - a new company law reform was recently adopted in Luxembourg, introducing, a.o., a new article 1865bis in the Civil Code that allows “dissolution-confusion” in one-shareholder companies. The question can be raised whether this provision could be applied across the borders (f.e. could a French company being the sole shareholder of a Luxembourg company decide to dissolve it without having to consider the provisions of the Cross-Border Mergers Directive ?); - another provision of the recently adopted company law reform does re-balance things when considering the cross-border merger as a means for the company to change “nationality” (or law applicable thereto). In the past companies were eventually forced to use the detour of the CBM in order to avoid the requirement of unanimity imposed by law for the transfer of the seat. Since aforementioned reform unanimity is no longer required for the cross-border transfer of the seat. The usefulness of the Cross-Border Merger Directive is therefore not in the least questioned in Luxembourg but it is regrettable that this would appear part of a “work-in-progress” that however does not show concrete signs of being completed any time soon.

The emerging experience of cities in the Global South regarding the complexity of their response to territorial competition's pressures requires the rethinking of the very concept of urban competitiveness. This study proposes the distributionally-sensitive modeling of urban competitiveness (DS-MUC) in a perspective that is driven by the norm of Equity. The DS-MUC is posited as a critical theory to neoliberalism and as a contribution to the social sustainability and to the normative investigation of post-capitalist urban transformations in the Global South.The application of the DS-MUC in the investigation of Da Nang in Vietnam and Cebu City in the Philippines reveals that an interactive, relational and network-based entrepreneurial governance's capacity has a much greater proclivity to deliver Equity and therefore to achieve a 'high-quality competitiveness' than a city's organizing capacity embedded in illiberal, state-paternalistic and public-sector monopolistic arrangements.

Recent years have seen much debate concerning the interplay between human rights and corporations. Part of that debate has focused on corporate violations of human rights norms and possible legal accountability mechanisms for such breaches. The present research is concerned with one such accountability mechanism, namely litigation before domestic courts seeking to enforce corporations’ international obligations and the complaints before the OECD National Contact Points (‘NCPs’). The thesis analyses how domestic courts and the OECD NCPs have conceptualised and implemented corporations’ human rights obligations. It is premised on the assumption that, through their application of international norms in their particular national context, these institutions act to crystallize and clarify the ambit of such norms.

We investigate the class of binary associative and quasitrivial operations on a given finite set. Here quasitriviality (also known as conserva-tiveness) means that the operation always outputs one of its input values. We also examine the special situations where the operations are commutative and nondecreasing. In the latter case, these operations reduce to discrete uninorms, which are discrete fuzzy connectives that play an important role in fuzzy logic. As we will see nondecreasing, associative and quasitrivial operations are chara-cterized in terms of total and weak orderings through the so-called single-peakedness property introduced in social choice theory by Duncan Black. This will enable visual interpretaions of the above mentioned algebraic properties. Motivated by these results, we will also address a number of counting issues: we enumerate all binary associative and quasitrivial operations on a given finite set as well as of those operations that are commutative, are nondecreasing, have neutral and/or annihilator elements. As we will see, these considerations lead to several, previously unknown, integer sequences. [less ▲]

We describe the application in security of shells of Cholesteric Liquid Crystals (ChLCs). Such shells have a diameter in the microns range and can be gathered in hundreds in a surface area as small as a nail’s head. Because of their structural properties, a bundle of them reflects light, creating colorful patterns that we argue to be unique and computationally hard to predict. We argue also that the bundle itself is unclonable. These are typical properties of Physically Unclonable Functions, a family to which shells of ChLCs belong too. Herein we discuss their physical and security properties and their potential use in object authentication. [less ▲]

Study objective: Patients expect a lot from doctors. They expect doctors to be trustworthy and competent, to discuss all treatment options with them, to inform them about mistakes made during the treatment and to put their interests before their own interests. This paper examines how the population of Europe assesses doctors in this respect and whether there are countries where the assessments are similar. Methods: In the "International Social Survey Programme - ISSP" the population in 32 countries was asked to assess the doctors in their respective countries. For this paper, data of 27,772 respondents from 18 European countries were analysed. The respondents were asked to rate 5 statements about doctors on a 5-point scale, with 1 indicating a positive assessment and 5 indicating a negative assessment. For each country, the mean values for the statements were calculated and grouped using cluster analysis to identify countries with similar assessments. Results: "Doctors can be trusted" is the statement with the highest approval across all countries, with means ranging from 2.0 in Denmark to 2.7 in Russia. In most countries, the means of the following statements were close to each other: "Doctors discuss all treatment options with their patients", "The medical skills of doctors are as good as they should be", and "Doctors do not care more about their earnings than about their patients." In almost all countries, respondents were particularly skeptical about the statement "Doctors would tell their patients if they had made a mistake during treatment". Four clusters were identified, but there was no cluster that rated among the best for all five statements. With regard to trust, the discussion of treatment options and the pursuit of self-serving interests, doctors in Germany were not rated particularly well or particularly badly. In Germany, the population was more likely to think that doctors would not inform their patients about mistakes during the treatment. Conclusions: Trust in doctors seems to reflect the general level of trust in a country. The question arises why trust in doctors is high across countries if the respondents are much more skeptical regarding the other statements. [less ▲]
