The notion of ‘basic vocabulary’ is associated with the linguist and anthropologist Morris Swadesh, who proposed a list of 200 (and later 100) items. These lists, while widely used in historical and comparative linguistics, are based on Swadesh’s intuitions rather than on empirical research. More recently, however, the Leipzig Loanword Typology Project conducted a cross-linguistic survey of loanwords (Haspelmath & Tadmor 2009). One of the results is a 100-item list of basic vocabulary entries — the ‘Leipzig-Jakarta list of basic vocabulary.’ This list is the product of four factors, computed for a database of 1440 meanings in 41 languages: borrowability, representation in the database, analyzability / simplicity, and age. As Tadmor (2009) points out, this is the first list of basic vocabulary items based on extensive cross-linguistic comparison, and it constitutes a ‘full-fledged basic vocabulary’ that ‘comprises the notions normally associated with this concept: stability (our age score), universality (our representation score) and simplicity (our analyzability score), as well as resistance to borrowing (our unborrowed score)’ (2009: 68). In this talk, we examine this list of 100 meanings in order to evaluate the influence of Greek on the Coptic basic vocabulary, or — to put it the other way around — the ‘Egyptian¬ness’ of the Coptic lexicon, which seems to reflect an intense language contact situation. As a first step, Coptic data were collected from Crum (1939), the most extensive Coptic dictionary, for four dialects: Sahidic, Bohairic, Fayyumic, and Akhmimic. All Coptic lexemes associated with a meaning on the list were collected, even if poorly attested. Additionally, a questionnaire was been submitted to Copticists in order to detect Greek loanwords that would also be used for expressing these 100 meanings. Furthermore, we used etymological tools (Černý 1976; Westendorf 1977; Vycichl 1983) in order to attribute an age score (from 0 = Greek loanword to 4 = Old Egyptian) to the lexemes at two levels: the formal level (when is the word first attested in Ancient Egyptian) and the semantic level (when is the Coptic meaning first associated with this word). The vast majority of meanings (ca. 85%) have at least one pre-Coptic Egyptian cognate, most of which are already attested in Old Kingdom texts. As a result of this study, we are able (1) to evaluate the influence of Greek on the basic vocabulary of the main Coptic dialects, (2) to describe the basic vocabulary of Coptic dialects independently and to observe how they differ from one another, (3) to produce a first estimate of the rate of change in basic vocabularies over the course of Egyptian as a whole.

Preterm premature rupture of membranes (PPROM) likely results from weakening of the constituent connective tissue. It is uncertain if the alterations are limited to the fetal membranes or are also present in other sites such as the skin. The aim of the study was to compare the dermal structure of women suffering from recurrent PPROM with the dermis of both non-pregnant women and women with uneventful gestation. Skin biopsies were taken from 42 women who recently underwent PPROM, 33 women with uneventful gestation and 33 non-pregnant women. Histochemistry, immunohistochemistry, and electron microscopy were performed on these specimens and analyzed blindly. Morphologic changes were found in the dermis of most (33 of 42 at optical microscopy and 40 of 42 at ultrastructure) of the women suffering from PPROM. They were reminiscent of those found in some types of Ehlers-Danlos Syndrome (EDS). However, there was no clinical evidence suggesting a recognized form of EDS. We conclude that some cases of PPROM are a systemic connective tissue disorder representing a yet unidentified type of EDS. [less ▲]

Electrostatic actuators are often used in MEMS since they are relatively easy to manufacture and provide a short response time. Previous studies have already considered topology optimization of such micro-actuators like the work by Raulli and Maute [1] and by Yoon and Sigmund [2]. Raulli considers maximization of the actuator output displacement for given electric potential input locations. The paper by Yoon et al. goes further by replacing the staggered modeling used by Raulli by a monolithic approach where both physical fields (electric and mechanical) are solved at once. However, electrostatic micro-actuators possess a limit input voltage called the pull-in voltage, beyond which they become unstable. If a voltage greater than the pull-in voltage is applied to the device, elastic forces of the suspension system are not able to balance electrostatic forces and electrodes stick together. In some cases, the pull-in effect can damage the device. Previous researches by the authors [3] have considered the possibility to control pull-in voltage using topology optimization. In this first approach, pull-in voltage itself was included in the optimization problem and treated as objective function. Nevertheless, in some applications, the developed pull-in voltage optimization procedure suffers from design oscillations that prevent from reaching solution. As illustrated in this paper, the issue is similar to the mode switching problem that arises in eigenvalue optimization problems. The classical solution to this issue consists in including several eigenvalues in a ‘max-min’ formulation. However as the classical pull-in voltage optimization problem is not formulated as an eigenproblem, direct application is not possible. Indeed, pull-in being a nonlinear instability phenomenon, strictly speaking, it is only possible to compute one instability mode and upcoming instability modes cannot be captured. Therefore, this paper is dedicated to the development of a linear eigenproblem approximation for the nonlinear stability problem after the work on nonlinear buckling by Lindgaard and Lund [4]. The proposed stability eigenproblem leads to an alternative optimization procedure aiming at maximizing pull-in voltage. The first eigenmode corresponds to the actual pull-in mode while higher order modes allow estimating upcoming instability modes. Using a multiobjective formulation to maximize the smallest eigenvalue of the stability problem, it is possible to circumvent oscillation issues met with pull-in voltage optimization. Moreover, numerical results show that even if the eigenproblem formulation is an approximation of the actual pull-in voltage optimization problem, eigenproblem formulation leads to significant improvement of pull-in voltage.

We propose a model-independent analysis of the neutrino mass matrix through an expansion in terms of the eigenvectors defining the lepton mixing matrix, which we show can be parametrized as small perturbations of the tribimaximal mixing eigenvectors. This approach proves to be powerful and convenient for some aspects of lepton mixing, in particular when studying the sensitivity of the mass matrix elements to departures from their tribimaximal form. In terms of the eigenvector decomposition, the neutrino mass matrix can be understood as originating from a tribimaximal dominant structure with small departures determined by data. By implementing this approach to cases when the neutrino masses originate from different mechanisms, we show that the experimentally observed structure arises very naturally. We thus claim that the observed deviations from the tribimaximal mixing pattern might be interpreted as a possible hint of a ``hybrid'' nature of the neutrino mass matrix. [less ▲]
