Following the advent of new Information and Communication Technologies such as smartphones and social networks, the boundaries between what is public and what is private have shifted significantly. While concerns have been expressed by the population regarding the erosion of privacy, as in the case of the Patriot Act or Wikileaks, individuals also deliberately share a lot of personal information online. This has led some thinkers to propose that a “reciprocal transparency”, which would entail a nearly unlimited access to any kind of information for every citizen, might be an alternative to actual privacy laws, which are severely hampered by the pervasiveness of new surveillance technologies. By adopting the approach and the theories of Science and Technology Studies, this research aims at analysing the three cornerstones which underpin the argumentation in favour of transparency. By doing so, it demonstrates that discourses advocating for such transformations rely on the erroneous belief that technology determines social change, on a misconception of privacy, and finally on a utopian vision of transparency. These observations lead to the conclusion that reciprocal transparency is not so much simply a solution to modern ICT-related privacy issues as an ideological view of the world. [less ▲]

Some of the D-amino acids (D-Ser, D-Asp, D-Glu) have gained an increasing attention during the last decades, due to the discovery of their role as neurotransmitters and their implication in different neurological pathologies (Alzheimer’s disease, schizophrenia etc.). Nevertheless, their use as biomarkers is particularly relevant when correlated with the levels of other neurotransmitters. In order to develop a fast and efficient separation method widely accessible for the quantitation of these molecules, we used only common separation tools such as RP-18 stationary phases for reversed phase liquid chromatography (RP-LC) or bare fused capillaries for capillary zone electrophoresis (CZE). For achieving chiral resolution, a derivatization procedure was implemented. (-)-FLEC was the chiral derivatization agent of choice due to its fast and quantitative reaction with primary and secondary amines and the ability of performing in-capillary derivatization. Moreover, the derivatization process implies only a simple mix of the sample and reagent, at room temperature. The separation of the FLEC derivatives of several biologically relevant D- and L- amino acids (Asp, Glu, Ser, Tyr, Trp, Phe, His) together with certain neurotransmitter molecules have been optimized using CZE or RP-LC, chiral resolution being achievable for all amino acids of interest. By the CZE approach the running buffer’s pH turned out to be critical in achieving baseline separation of the targeted analytes. The derivatives of most amino acids could be separated using 60mM acetate buffer at pH 5, while for Asp derivatives the separation could be achieved only at pH 4. Being stronger bases, a third run at a more alkaline pH was needed for the separation of the remainder neurotransmitters. Moreover, the implemented in-capillary derivatization allows a fast and fully automated separation procedure. As for the RP-LC approach 50 mM acetate buffer in combination with an organic modifier (methanol, acetonitrile or tetrahydrofuran (THF)) was tested as mobile phase using gradient elution. Once again, the strong influence of pH on the resolution was observed. The organic modifier nature was of critical importance, where only THF enabled baseline resolution for all amino acid derivatives. [less ▲]

Polycystic kidney diseases (PKDs) are genetic disorders that can cause renal failure and death in children and adults. Lowering cAMP in cystic tissues through the inhibition of the type-2 vasopressin receptor (V2R) constitutes a validated strategy to reduce disease progression. We identified a peptide from green mamba venom that exhibits nanomolar affinity for the V2R without any activity on 155 other G-protein–coupled receptors or on 15 ionic channels. Mambaquaretin-1 is a full antagonist of the V2R activation pathways studied: cAMP production, beta-arrestin interaction, and MAP kinase activity. This peptide adopts the Kunitz fold known to mostly act on potassium channels and serine proteases. Mambaquaretin-1 interacts selectively with the V2R through its first loop, in the same manner that aprotinin inhibits trypsin. Injected in mice, mambaquaretin-1 increases in a dose-dependent manner urine outflow with concomitant reduction of urine osmolality, indicating a purely aquaretic effect associated with the in vivo blockade of V2R. CD1-pcy/pcy mice, a juvenile model of PKD, daily treated with 13 μ𝝁g of mambaquaretin-1 for 99 d, developed less abundant (by 33%) and smaller (by 47%) cysts than control mice. Neither tachyphylaxis nor apparent toxicity has been noted. Mambaquaretin-1 represents a promising therapeutic agent against PKDs. [less ▲]

Roots, the belowground part of plants, play a major role in plant development. Their study in field conditions is important to identify suitable soil management practices for suitable crop production but roots are hidden by soil and their study is therefore difficult. Estimation of root system development is often based on the soil coring method which allows repeated measurements during the growing season in the field as well as in different soil horizons. However, this method is limited due to the time needed to extract roots from soil cores and to manually sort them from crop residues before quantification. To avoid this tedious sorting step and remove operator subjectivity, a faster sorting method was developed. Near infrared hyperspectral imaging (NIR-HIS) was tested as a rapid method to quantify the amount of roots in soil samples. [less ▲]

Il n’est en philosophie d’héritage que gagné. Et en m’installant dans cette ambigüité propre au savoir philosophique, j’examine, dans ce texte, un développement peu étudié de la pensée sartrienne : sa théorie du « circuit de l’ipséité » de la conscience. Quant à mon objectif, il s’agira de faire le point sur le processus de maturation intellectuelle à l’issue duquel Sartre conçut l’ipséité comme un circuit. Ainsi je mets en évidence que certaines des réflexions de Heidegger, Bergson et Mauss, sur la notion d’identité personnelle ont constitué les héritages philosophiques mobilisés et transformés par la théorie sartrienne de l’ipséité.

This paper proposes a novel control scheme for frequency support among asynchronous AC areas through HVDC grids. It is based on local controllers, each acting on a voltage source converter, using locally available measurements only, and supporting frequency of the adjacent AC area after a significant disturbance. The controller is combined with the existing DC voltage droop technique and is inspired of Model Predictive Control, taking into account various constraints. The coordination of the proposed control scheme with the existing secondary frequency control of an AC area is also discussed. Examples obtained from a test system with a five-terminal DC network connecting two asynchronous areas demonstrate the effectiveness of the proposed control scheme. [less ▲]

A real-time control scheme is proposed to correct undesired voltages in distribution networks by adjusting the reactive powers produced by Dispersed Generation Units (DGUs). This is performed at two levels: locally, in DGU controllers, and centrally by a supervisory controller acting on some of the DGUs only. The centralized, discrete controller solves a multi-time-step constrained optimization inspired of Model Predictive Control. Unacceptable voltage deviations are partially but rapidly corrected by the local controls. Further but slower corrections are applied by the upper level, taking advantage of the coordination between DGUs. This hybrid control is of practical interest where the deployment of the upper level control is not feasible or affordable over all DGUs. The proposed method effectiveness is demonstrated on a 75-bus test system. [less ▲]

Cyber-security requires not only technical preparations but also organizational practices that reduce the likelihood and severity of damage to the organization. Although user compliance to security policies has been examined in prior literature, user behaviour is only one facet of an organization’s cyber-security; the actions of the IT staff, crisis team, and the management are just as critical. Consequently, organizational practices in cyber-security are not understood very well. To address this gap, this research applied the concept of mindfulness, which has recently received attention also in the IT field. We collected data from a revelatory case – that of a government agency that was targeted by a large-scale cyber-attack – and applied the concept of mindfulness in analyzing the data. Our analysis uncovered a number of mindful practices related to cyber-security. These practices can serve as a building block to theorize on the activities to be taken by IT workers in promoting cyber-security. Our paper also suggests avenues for further research in the emerging topic, for instance, through the concept of cyber-security capability. [less ▲]
