Canadian federalism and its future are undeniably a frequent and important topic of debate. Many people have their own opinions on the topic but they rarely have the opportunity to discuss it with fellow Canadians, experts and politicians in a setting conducive to learning and debate. With this in mind, three small citizens' assemblies on the future of federalism in Canada were held in the spring of 2008, two in Montreal and one in Kingston. For over four hours, participants had the opportunity to learn about and discuss topics relating to federalism with experts, politicians and other Canadians. The qualitative and quantitative data collected throughout these meetings provide a clearer picture of Canadians' perceptions and preferences regarding the future of their country and their province. The initial results show a wide range of knowledge, attitudes and opinions among participants at a single meeting and from one meeting to the next. There is no clear profile of a “federal citizen” but rather a multitude of profiles, sometimes very diverse. For comparison purposes, two more citizens' assemblies will be held in Belgium to compare French-speaking and Flemish-speaking Belgians' perceptions and preferences regarding federalism. [less ▲]

The manufacturing of small metallic components for MEMS is a great challenge for industries. However, the lack of knowledge about the mechanical behavior of metals when they are employed in small components can reduce the economical development of MEMS due to manufacturing and reliability issues. The objective of this work is to provide new scientific results to improve the understanding of the mechanical properties of micro-components. Experimental and numerical (strain gradient plasticity model) tensile tests are performed on thin nickel single crystals and polycrystals (thickness larger than 10 m) showing different size effects depending on the dimensions of the samples. These effects are then taken into account in new simplified numerical models for the prediction of micro-forming processes. [less ▲]

A Raman spectrometer will be utilized on a planetary exploration mission for the first time when the ExoMars rover is launched in 2018. A Raman spectroscopy instrument was selected for inclusion on the ExoMars mission because of its ability to assess the habitability and to search for evidence of life on Mars. Indeed Raman spectrometers have the capability to detect geological substances which are inorganic molecules and inorganic molecular ions constituting the rocky surface of Mars. Information on the nature of rocks present on the surface of Mars will provide information about the habitability of the planet. Besides the detection of geomarkers, Raman spectrometers have the ability to detecting potential biological-derivative substances, often referred to as biomarkers. These biomarkers are organic molecules originating from extent or extinct living organisms. In preparation for ExoMars, it is crucial to study the detection capability of miniaturized Raman spectrometers (specifically developed for space missions and therefore compromised by the associated challenging constraints such as minimal power budget, mass budget, data budget and overall envelope) on both lab synthetic samples and natural terrestrial analogues samples. We present here a systematic comparison of the capability of a number of Raman spectrometer designs/configurations to detect biomarkers in geological matrices that are relevant to the Martian surface and subsurface. In particular, we will compare spectral images recorded with benchtop instruments and a Raman Laser Spectrometer prototype developed at the University of Leicester to optimize/characterize the camera system that will be used for the ExoMars mission. Several parameters such as the excitation wavelength, the number of spectra recorded per sample and selection of optimal operating modes will be discussed. As an example, the habitability of desert varnish in the context of planetary exploration will be discussed in detail. Desert varnish are mineral coatings comprising clay, iron oxide and manganese oxide which are associated with living organisms in many stable extreme environment on Earth. Desert varnish are recognized as terrestrial analogue samples for martian surface because similar mineral formation have been recently identified on Mars. [less ▲]

We look for minimal chiral sets of fermions beyond the standard model that are anomaly free and, simultaneously, vectorlike particles with respect to color SU(3) and electromagnetic U(1). We then study whether the addition of such particles to the standard model particle content allows for the unification of gauge couplings at a high energy scale, above 5.0 × 1015 GeV so as to be safely consistent with proton decay bounds. The possibility to have unification at the string scale is also considered. Inspired in grand unified theories, we also search for minimal chiral fermion sets that belong to SU(5) multiplets, restricted to representations up to imension 50. It is shown that, in various cases, it is possible to achieve gauge unification provided that some of the extra fermions decouple at relatively high intermediate scales. [less ▲]

In this work we study which are the minimal anomaly-free chiral fermion sets, beyond the standard model, that lead to vector-like particles with respect to SU(3) and U(1)em after symmetry breaking. We focus on fermion multiplets with SU(3) and SU(2) dimensions less than or equal to 10 and 5, respectively. Furthermore, we study whether the addition of such chiral fermions allows for gauge coupling unification, at some high scale compatible with proton decay limits. [less ▲]

We study the structure of automata accepting the greedy representations of N in a wide class of numeration systems. We describe the conditions under which such automata can have more than one strongly connected component and the form of any such additional components. Our characterization applies, in particular, to any automaton arising from a Bertrand numeration system. Furthermore, we show that for any automaton A arising from a system with a dominant root beta>1, there is a morphism mapping A onto the automaton arising from the Bertrand system associated with the number beta. Under some mild assumptions, we also study the state complexity of the trim minimal automaton accepting the greedy representations of the multiples of m>1 for a wide class of linear numeration systems. As an example, the number of states of the trim minimal automaton accepting the greedy representations of mN in the Fibonacci system is exactly 2m^2. [less ▲]

A minimal cardiovascular system (CVS) model has been previously validated in silico, and in several animal model studies. It accounts for valve dynamics by means of a Heaviside function to simulate the “open on pressure, close on flow” law. However, this model does not describe the progressive valve opening and therefore, it is not suitable for studying valve dysfunctions. [less ▲]

Antipsychotic therapy is frequently associated with several side effects such as hyperprolactinemia. The influence of a putative antipsychotic JL 13 on prolactin release was assessed after intraperitoneal injection in gentled male rats in comparison with clozapine and haloperidol. A total of 30 or 150 min after administration, whole blood was collected for preparing serum samples. Prolactin was quantified by radioimmunoassay method. At 30 min, JL 13 like clozapine, increased prolactin concentration only at the higher dose (30 mg/kg) while haloperidol at both tested doses induced a dramatic increase of prolactin concentration. At 150 min after injection, only haloperidol (0.3 mg/kg) significantly increased serum prolactin level. This minimal effect on prolactinemia reinforces the similarity of clozapine and JL 13 regarding the atypical antipsychotic profile. (C) 2002 Elsevier Science Ireland Ltd. All rights reserved.

A simulation study has been used to evaluate the minimal error rate of three affectation rules and to compare five estimators of this error rate for two groups of observations, in 480 situations characterized by the distribution and to the overlap of the populations, the number of variables, the sample size and the heteroscedasticity degree of the population under study. The results of this study suggest that the quadratic rule might be the best for heteroscedastic normal models. The linear rule showed better performance for homoscedastic normal or moderate non-normal models. The logistic rule is the best for severe non-normal models except when homoscedasticity occurs. As far as the comparison of five estimators is concerned, the results of the study indicate that eDS and eB are the best estimators of the minimal error rate for the linear rule, e5 for the quadratic rule and eD for the logistic rule.

We had previously predicted successfully the minimal fusion peptides (FPs) of the human immunodeficiency virus 1 (HIV-1) gp41 and the bovine leukemia virus (BLV) gp30 using an original approach based on the obliquity/fusogenicity relationship of tilted peptides. In this paper, we have used the same method to predict the shortest FP capable of inducing optimal fusion in vitro of the simian immunodeficiency virus (SIV) mac isolate and of other SIVs and human immunodeficiency virus (HIV-2) isolates. In each case, the 11-residue-long peptide was predicted as the minimal FP. For the SIV mac isolate, liposome lipid-mixing and leakage assays confirmed that this peptide is the shortest peptide inducing optimal fusion in vitro, being therefore the minimal FP. These results are another piece of evidence that the tilted properties of FPs are important for the fusion process and that our method can be used to predict the minimal FPs of other viruses.

The present study aimed at investigating the influence of the time interval between injection of regular insulin and meal ingestion on postprandial glucose changes and overall blood glucose control in patients with type 1 diabetes on intensive insulin therapy. Fifteen C-peptide negative subjects were submitted, in a randomized order, to two 6-week treatment periods in which regular insulin was injected either 5 minutes or 30 minutes before each of the three main meals, in combination with a bedtime NPH insulin injection. The changes in plasma glucose excursions following a breakfast test (Cmax, Tmax, Cmin, Tmin, AUC0-240 min) were similar in the two experimental protocols. Furthermore, no significant changes were observed in daily insulin dosages nor in glucose profiles obtained using home blood glucose monitoring. Only a tendency to a greater 90-minutes postprandial increase in blood glucose levels was observed when regular insulin was injected 5 minutes rather than 30 minutes before meal. Glycated haemoglobin levels were similar after each treatment period (7.6 +/- 0.2% versus 7.5 +/- 0.2%; NS) and no differences in the incidence or severity of hypoglycaemic episodes were noticed between the two insulin schemes. In conclusion, in type 1 diabetic patients who are rather well controlled with a basal-bolus insulin scheme, the injection of regular insulin 30 minutes before each main meal provides no significant advantage as compared to the injection of regular insulin 5 minutes before meal.
