Silicon-based substrates for the epitaxy of HgCdTe are an attractive low-cost choice for monolithic integration of infrared detectors with mature Si technology and high yield. However, progress in heteroepitaxy of CdTe/Si (for subsequent growth of HgCdTe) is limited by the high lattice and thermal mismatch, which creates strain at the heterointerface that results in a high density of dislocations. Previously we have reported on theoretical modeling of strain partitioning between CdTe and Si on nanopatterned silicon on insulator (SOI) substrates. In this paper, we present an experimental study of CdTe epitaxy on nanopatterned (SOI). SOI (100) substrates were patterned with interferometric lithography and reactive ion etching to form a two-dimensional array of silicon pillars with similar to 250 nm diameter and 1 mu m pitch. MBE was used to grow CdTe selectively on the silicon nanopillars. Selective growth of CdTe was confirmed by scanning electron microscopy (SEM), atomic force microscopy (AFM), and X-ray photoelectron spectroscopy (XPS). Coalescence of CdTe on the silicon nanoislands has been observed from the SEM characterization. Selective growth was achieved with a two-step growth process involving desorption of the nucleation layer followed by regrowth of CdTe at a rate of 0.2 angstrom s(-1). Strain measurements by Raman spectroscopy show a comparable Raman shift (2.7 +/- 2 cm(-1) from the bulk value of 170 cm(-1)) in CdTe grown on nanopatterned SOI and planar silicon (Raman shift of 4.4 +/- 2 cm(-1)), indicating similar strain on the nanopatterned substrates.

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 ▲]

A survey was carried out in 4 ecological zones (Northeastern, Northwest, the Red river delta and North central coast) of Vietnam to examine influence of ecological zone, education level, extension activity, household economy and herd size on utilization of rice straw and maize stover as feeds for buffaloes and cattle. A total of 720 households, of which 497 raised buffaloes and cattle, were interviewed. Results showed that the proportion of household using rice straw and maize stover as feed was significantly different among ecological zones and education levels. All of the studied factors, except the economic level, significantly influenced the utilization of rice straw and maize stover as feeds for buffaloes and cattle. [less ▲]

Partant du constat que la majeure partie des débats concernant un éventuel « primat de la raison pratique » se jouent pour ainsi dire en amont de la phénoménologie husserlienne, j’entreprends d’abord de retracer les deux sources de la thèse du « primat de la raison pratique », telle qu’elle est défendue dans l’école néokantienne de Bade, à savoir la source kantienne- fichtéenne, qui concerne le caractère « normatif » du critère de validité de la connaissance, et la source brentanienne-bergmannienne, qui concerne le caractère « pratique » des actes judicatifs. J’examine ensuite brièvement les deux stratégies développées respectivement par Rickert et par Lask pour écarter l’objection de « moralisme » : l’idée d’un « parallélisme logico- éthique » (Rickert) et la critique du concept de Sollen (Lask).

In rodents, parts of the arginine-vasopressin (AVP) neuronal system are sexually dimorphic with males having more AVP-immunoreactive cells/fibers than females. This neuropeptide neuronal system is highly sensitive to steroids and has been proposed to play an important role in the processing of olfactory cues critical to the establishment of a social memory. We demonstrate here that gonadally intact male aromatase knockout (ArKO) mice, which cannot aromatize androgens into estrogens due to a targeted mutation in the aromatase gene, showed severe deficits in social recognition as well as a reduced AVP-immunoreactivity in several brain regions. To determine whether this reduction is due to a lack of organizational or activational effects of estrogens, we assessed social recognition abilities and AVP-immunoreactivity in male ArKO and wild-type (WT) mice when treated with estradiol benzoate (EB) in association with dihydrotestosterone propionate (DHTP) in adulthood. Adult treatment with EB and DHTP restored social recognition abilities in castrated ArKO males since they showed normal female-oriented ultrasonic vocalizations and were able to recognize an unfamiliar female using a habituation-dishabituation paradigm. Furthermore, adult treatment also restored AVP-immunoreactivity in the lateral septum of ArKO males to levels observed in intact WT males. These results suggest that social recognition in adulthood and stimulation of AVP expression in the adult mouse forebrain depend predominantly on the estrogenic metabolite of testosterone. Furthermore, our results are in line with the idea that the organization of the AVP system may depend on androgen or sex chromosomes rather than estrogens. [less ▲]

Optimal delivery of health care is a common goal of individual physicians, professional organizations, hospital structures and governmental authorities. A growing concern has emerged from the public, media and third payer organizations concerning the quality of care and the amount of resources spending. In the United States, large databases, guidelines and performance evaluation have been elaborated by medical societies, particularly in the area of cardiac surgery. These tools are useful for improvement of patients' care, resources distribution, pay for performance and public and practitioners' awareness. The evaluation of quality is based on composite models combining structure, process and outcome indices. However, pitfalls such as patients' selection, and risk avoidance in order to improve results must been prevented by adjustment of the treated populations' risk factors by specific scores. The Belgian Health authorities have built a structure directed at delivery of care improvement based on "Care Programs", monitored by Colleges formed by delegates of professional organizations. The College of Cardiac Surgery has promoted several studies aimed at data collection and evaluation. In 2007, a survey was addressed to all the Belgian Cardiac surgeons to define their opinion as to the best indicators of care in their specialty. These results will serve to define further avenues of research. By maintaining the responsibility of care evaluation in the hands of the involved professionals, this kind of cooperation between governmental and physicians' organizations seems to serve the best interests of the public and the practitioners.

GENIE, the Ground-based European Nulling Interferometer Experiment, will combine the lights collected in the L’ band by two VLT telescopes in a destructive way, thereby revealing the thermal and/or scattered emission of faint objects in the close neighbourhood of the target star. A prime scientific goal for GENIE thus consists in the detection and characterization of debris disks around nearby Vega-type stars. Thanks to its high angular resolution and operating wavelength (3.8 µm), GENIE will be particularly sensitive to the thermal emission from the warm dust standing within a few AU from the star, a part of the disks which is not accessible with current detection methods (IR photometric excesses, sub-millimeter imaging, …). In this paper, we investigate the capabilities of GENIE to detect and characterize the physical parameters of the debris disk around zeta Leporis, a prototypical Vega-type star suspected to harbour a warm dust component in its debris disk (Fajardo-Acosta et al., AJ 115, 2101). This study is then extended to the detection of faint exozodiacal disks around typical Darwin/TPF targets, thereby demonstrating the very high potential of GENIE in the field of high-contrast imaging.
