International audience; Although the problem of computing frequent queries in relational databases is known to be intractable, it has been argued in our previous work that using functional and inclusion dependencies, computing frequent conjunctive queries becomes feasible for databases operating over a star schema. However, the implementation considered in this previous work showed severe limitations for large fact tables. The main contribution of this paper is to overcome these limitations using appropriate auxiliary tables. We thus introduce a novel algorithm, called Frequent Query Finder (FQF), and we report on experiments showing that our algorithm allows for an effective and efficient computation of frequent queries.

International audience; Deterministic networking allows carrying data flows with low data-loss rates and with bounded latency. A typical use-case is the convergence of Operational Technology (OT) with Information Technology (IT), also known as the Industrial Internet. Wireless networks operate on a shared communication medium where the potential external interference along with multi-path fading impact data packet delivery. Since the medium is shared, it is not necessarily possible to employ wired techniques, such as preemption, to guarantee timely delivery. By employing diversity in the time, frequency and spatial domains, wireless technologies with scheduled transmissions, such as IEEE 802.15.4 Time Slot Channel Hopping (TSCH), can mitigate those effects and provide Reliable and Available Wireless communications that approach determinism. Nevertheless, a radio link operating in the ISM band, such as IEEE 802.15.4-TSCH, still needs to handle collisions and possibly re-transmission. Therefore, a single link cannot reliably ensure delivery at all times within bounded latency. It takes redundant links and paths to provide both the high availability and the near consistent reliability that industrial applications require. In this paper, we present the Packet Automatic Repeat reQuest (ARQ), Replication and Elimination (RE), and Overhearing (PAREO) functions to further increase the Quality of Service (QoS) in industrial networks, even when implemented on top of best-effort traffic in a shared network.

Abstract Fluorescein (F) species were encapsulated inside nanosized zeolites L and Y by their synthesis from adsorbed precursors (phthalic anhydride (Ph) and resorcinol (R)). The applied nanozeolites were modified either with H+ or Zn2+ cations and they played roles of the catalysts for synthesis of F and of the matrices for resulting dye molecules. The F loading, its tautomeric forms and optical properties of obtained composites depended on zeolite structure, morphology and on introduced cations. The composites usually showed higher fluorescence intensity than the pristine dye. The highest fluorescence intensity was noticed for the sample with nano-ZnL matrix. This intensity was much higher than that observed for composite with conventional micro-sized Zn L zeolite. Regarding an efficient fluorescence and nanosize of the obtained composites they seem promising fluorescent tracer for medical (theranostic) applications.

International audience; Attenuated total reflectance Fourier transform spectroscopy (ATR-FTIR) was applied on fresh (NF), freeze-dried (FD) and cell wall materials (AIS) of raw and processed apples. These samples prepared from 36 apple sets and the corresponding 72 purees, issued from different varieties, agricultural practices, storage periods and processing conditions, were used to build models including exploratory analysis, supervised classification and multivariate calibration. Fresh and freeze-dried samples presented similar fingerprint spectral variations due to processing. ATR-FTIR directly on fresh purees satisfactorily predicted textural properties such as particle average size and volume (RPD > 3.0), while freeze-drying improved assessment of chemical (RPD > 3.2) and rheological (RPD > 3.1) parameters using partial least-squares regression. The assessment of texture and macrocomponents of purees can be obtained with a limited sample preparation. For research applications because of a need of sample preparation, changes of cell wall composition during fruit processing could be assessed in relationship with pectin degradation.

, — The decay of 228Pa to the levels of 228Th has been extensively studied by various techniques. Single spectra of γ-and K X-rays have been measured with Si(Li) and Ge(Li) detectors. A set of two Ge(Li) detectors has been used to study γ-y and γ-K X-ray coincidences. Measurements of γ-spectra in coincidence with the selected internal-conversion lines have been carried out using a Ge(Li) detector and a six-gap magnetic β-spectrometer. Finally, spectra of internal-conversion electrons have been studied in a β-spectrometer which uses a Si(Li) detector placed together with a system of diaphragms in a homogeneous magnetic field. The decay scheme has been constructed including 39 levels of 228Th. It accounts for 111 of 160 transitions ascribed to the 228Pa activity. The electron-capture decay energy has been determined to be 2 103 /+16 /-12 keV. The strength distribution for the electron-capture feeding of the 228Th levels is analysed in terms of nuclear models. The Coriolis mixing of four octupole bands (K = 0, 1, 2 and 3) is studied in some detail. The coupling matrix elements deduced from the experiment are compared with the results of the microscopic-model calculations.

International audience; Thirty lactating dairy cows were used in a 333 Latin-square design to investigate the effects of a raw or extruded blend of linseed and wheat bran (70:30) on plasma and milk fatty-acids (FA). Linseed diets, containing 16.6% linseed blend on a dry-matter basis, decreased milk yield and protein percentage. They decreased the proportions of FA with less than 18 carbons in plasma and milk and resulted in cis -9, cis -12, cis -15 18:3 proportions that were more than three and four times higher in plasma and milk, respectively, whereas cis -9, cis -12 18:2 proportions were decreased by 10–15%. The cis -9, trans -11, cis -15 18:3 isomer of conjugated linolenic acid was not detected in the milk of control cows, but was over 0.15% of total FA in the milk fat of linseed-supplemented cows. Similarly, linseed increased plasma and milk proportions of all biohydrogenation (BH) intermediates in plasma and milk, including the main isomer of conjugated linoleic acid cis -9, trans -11 18:2, except trans -4 18:1 and cis -11, trans -15 18:2 in plasma lipids. In milk fat, compared with raw linseed, extruded linseed further reduced 6:0–16:0 even-chain FA, did not significantly affect the proportions of 18:0, cis -9 18:1 and cis- 9, cis -12 18:2, tended to increase cis -9, cis -12, cis -15 18:3, and resulted in an additional increase in the proportions of most BH intermediates. It was concluded that linseed addition can improve the proportion of conjugated linoleic and linolenic acids, and that extrusion further increases the proportions of intermediates of ruminal BH in milk fat.

International audience; Magnitudes of differential stress in the lithosphere, especially in the crust, are still disputed. Earthquake-based stress drop estimates indicate median values ca. 180 MPa, corresponding to a friction angle of ca. 10° to maintain the topographic relief between lowland and plateau for >10 Ma. The relative contribution of crustal strength to total lithospheric strength varies considerably laterally. In the region between lowland and plateau and inside the plateau the depth-integrated crustal strength is approximately equal to the depth-integrated strength of the mantle lithosphere. Simple analytical formulae predicting the lateral variation of depth-integrated stresses agree with numerically calculated stress fields, which show both the accuracy of the numerical results and the applicability of simple, rheology-independent, analytical predictions to highly variable, rheology-dependent stress fields. Our results indicate that (1) crustal strength can be locally equal to mantle lithosphere strength and that (2) crustal stresses must be at least one order of magnitude larger than median stress drops in order to support the plateau relief over a duration of ca. 10 Ma.

Dans No Thoroughfare de Charles Dickens et Wilkie Collins (f870), le déséquilibre de l’intrigue survient lorsque le « personnage principal » apprend qu’il est, et qu’à la fois, il n’est pas Walter Wilding. Les deux auteurs nous amènent à la limite de l’appellation, un procédé dont ils rappellent la complexité et dont ils proposent diverses déviances. Ils mettent en présence deux personnages, qui pour survivre dans le récit devront se poser la question des rapports complexes entre nom propre et référence. A travers deux modes de construction de personnages, Wilkie Collins et Charles Dickens illustrent le débat des logico-linguistes et y apportent leur participation. In No Thoroughfare by Charles Dickens and Wilkie Collins (1870), the main plot is starts on the “main character’s” learning that he both is and is not Walter Wilding. The two authors thus take us to the limits of naming, reminding us of the complexity of its process while they display various deviances of the naming process. Two characters are involved and their endurance in the narrative they consider the complex relations between proper noun and referent. Through two modes of character framing, Wilkie Collins and Charles Dickens illustrate and take part in the logico-linguists’ long existing debate on this issue.

International audience

The Leonetti law outlaws excessive professional practice leading to prolongation of life by medical means. Any treatment, including artificial nutrition may be withheld or withdrawn. The law defines 3 situations, in which : the patient is conscious and at end of life, conscious and not at end of life, and unconscious (whether or not at end of life). In the case of a conscious end of life patient who requests a limitation of care, the doctor is obliged to respect the patient’s request and inform the patient of the consequences. For a person who is not end of life the doctor must respect the patient’s request, inform him/her of the consequences and do all in his/her power to convince the patient, and the patient must repeat his/her request after a reasonable period of time. If a patient is unable to express his/her own will the law requires that the patient’s will and collegiate discussion, which must reach a consensus, be respected. The will of the unconscious patient should be investigated by the practitioner through advanced instructions which the patient may have written within 3 years, or failing this from reportage by the trusted person and those close to the patient. The law stipulates that the decision of the trusted person will prevail over any other non-medical opinion. The collegiate procedure indicates consultation with the care team and with a doctor other than the doctor in charge of the patient and not within that doctor’s line management. In all situations, the patient’s will, the medical decision and its justifications and medical actions will be recorded in the patient dossier for the purposes of transparency and the sick person will receive palliative care. La Loi Leonetti pose le refus de l’acharnement thérapeutique. La limitation ou arrêt des traitements (LATA) peut concerner tout traitement dont la nutrition artificielle. La loi encadre trois situations selon que le malade est conscient et en fin de vie, conscient et non en fin de vie, inconscient (en fin de vie ou non). Envers un malade conscient et en fin de vie qui demande une LATA, le médecin a les obligations de respecter sa demande et de l’informer des conséquences. Pour une personne qui n’est pas en fin de vie, le médecin doit respecter sa demande, l’informer des conséquences, mettre tout en œuvre pour le convaincre et le malade doit réitérer sa demande après un délai raisonnable. Si le malade est en incapacité d’exprimer sa volonté, la loi pose le respect de la volonté du malade et la collégialité de la discussion. La volonté du malade inconscient sera recherchée par le praticien au travers des directives anticipées qu’il aurait éventuellement rédigées moins de 3 ans avant, sinon des témoignages de sa personne de confiance et de ses proches. La loi pose que l’avis de la personne de confiance, en l’absence de directives anticipées, prévaut sur tout autre avis non médical. La procédure collégiale signifie une consultation de l’équipe de soin et d’un autre médecin que le médecin en charge du patient, sans rapport de hiérarchie entre eux. Dans tous les cas, la volonté du malade, la décision médicale et ses motivations, et l’action médicale sont inscrites dans le dossier du malade dans un souci de transparence et la personne malade reçoit des soins palliatifs.
