The classical paradigm of the neural brain as the seat of human natural intelligence is too restrictive. This paper defends the idea that the neural ectoderm is the actual brain, based on the development of the human embryo. Indeed, the neural ectoderm includes the neural crest, given by pigment cells in the skin and ganglia of the autonomic nervous system, and the neural tube, given by the brain, the spinal cord, and motor neurons. So the brain is completely integrated in the ectoderm, and cannot work alone. The paper presents fundamental properties of the brain as follows. Firstly, Paul D. MacLean proposed the triune human brain, which consists to three brains in one, following the species evolution, given by the reptilian complex, the limbic system, and the neo-cortex. Secondly, the consciousness and conscious awareness are analysed. Thirdly, the anticipatory unconscious free will and conscious free veto are described in agreement with the experiments of Benjamin Libet. Fourthly, the main section explains the development of the human embryo and shows that the neural ectoderm is the whole neural brain. Fifthly, a conjecture is proposed that the neural brain is completely programmed with scripts written in biological low-level and high-level languages, in a manner similar to the programmed cells by the genetic code. Finally, it is concluded that the proposition of the neural ectoderm as the whole neural brain is a breakthrough in the understanding of the natural intelligence, and also in the future design of robots with artificial intelligence.

The ITRS Roadmap highlights the electrical characterization of the source and drain extension regions as a key challenge for future complimentary-metal-oxide-semiconductor technology. Presently, an accurate determination of the depth of ultrashallow junctions can routinely only be performed by time-consuming and destructive techniques such as secondary ion mass spectrometry (SIMS). In this work, the authors propose to use the fast and nondestructive photomodulated optical reflectance (PMOR) technique , as implemented in the Therma-Probe\textregistered (TP) dopant metrology system, for these purposes. PMOR is a pump-probe technique based on the measurement of the pump-induced modulated change in probe reflectance, i.e., the so-called (photo) modulated reflectance. In this article, the authors demonstrate that the absolute junction depths of boxlike active dopant structures can be extracted in a very simple and straightforward way from the TP offset curves, which represent the behavior of the modulated reflectance as a function of the pump-probe beam spacing. Although the procedure is based on the insights into the physical behavior of the offset curves, no modeling is involved in the actual extraction process itself. The extracted junction depths are in good correlation with the corresponding junction depths as measured by means of SIMS. The technique has a subnanometer depth sensitivity for depths ranging from 10 to 35 nm with the present Therma-Probe\textregistered 630XP system. The extension of the proposed procedure to the general ultrashallow profiles is also explored and discussed [less ▲]

We report high quality InP layers selectively grown in shallow trench isolation structures on 6 degree offcut Si (001) substrates capped with a thin Ge buffer layer. The Ge layer was used to reduce the thermal budget for surface clean and double step formation. The atomic steps on the Ge surface were recovered after a bake at 680°C. Smooth nucleation layer was obtained at 420°C on the Ge surface. Baking the Ge surface in As ambient facilitates the InP nulceation and improves the InP crystalline quality. This improvement is attributed to the effective As adsorption on the Ge surface and the polar Ge:As surface prevents the islanding of InP seed layer. Stacking faults were found in the InP layers as a result of threading dislocation dissociation and high quality InP layers were obtained in trenches with aspect ratio greater than 2. [less ▲]

The objective of this study was to assess changes in membrane permeability during rehydration of freeze-dried Weissella paramesenteroides LC11. Viability was assessed using the electrical conductivity measurement (ms cm-1 g-1 dry weight) and the plate count method (cfu g-1 dry weight). The symptoms of injury included an increase in the electrolyte leakage during the first 4 h of rehydration in Milli Q water and a decrease in the survival rate (about 64%), suggesting an increase in membrane permeability during dehydration. During rehydration of the freeze-dried strain, an increase in the temperature, NaCl or monosodium glutamate concentration and a decrease in H+ concentration resulted in an increase in the electrolyte leakage and a decrease in the survival rate (from about 5% to 97%, with respect to the treatment made). However, a decrease in the electrolyte leakage was observed with increasing glycerol, sucrose or maltodextrin and resulted in the maintenance of cell viability. Change in membrane permeability might lead to electrolyte leakage during rehydration and, ultimately, cell death. The electrolyte leakage assay associated with the plate count method, a quick and inexpensive method, could be used to evaluate dried bacteria resistance to dehydration. [less ▲]

There has been much concern regarding the role of dietary fructose in the development of metabolic diseases. This concern arises from the continuous increase in fructose (and total added caloric sweeteners consumption) in recent decades, and from the increased use of high-fructose corn syrup (HFCS) as a sweetener. A large body of evidence shows that a high-fructose diet leads to the development of obesity, diabetes, and dyslipidemia in rodents. In humans, fructose has long been known to increase plasma triglyceride concentrations. In addition, when ingested in large amounts as part of a hypercaloric diet, it can cause hepatic insulin resistance, increased total and visceral fat mass, and accumulation of ectopic fat in the liver and skeletal muscle. These early effects may be instrumental in causing, in the long run, the development of the metabolic syndrome. There is however only limited evidence that fructose per se, when consumed in moderate amounts, has deleterious effects. Several effects of a high-fructose diet in humans can be observed with high-fat or high-glucose diets as well, suggesting that an excess caloric intake may be the main factor involved in the development of the metabolic syndrome. The major source of fructose in our diet is with sweetened beverages (and with other products in which caloric sweeteners have been added). The progressive replacement of sucrose by HFCS is however unlikely to be directly involved in the epidemy of metabolic disease, because HFCS appears to have basically the same metabolic effects as sucrose. Consumption of sweetened beverages is however clearly associated with excess calorie intake, and an increased risk of diabetes and cardiovascular diseases through an increase in body weight. This has led to the recommendation to limit the daily intake of sugar calories. [less ▲]

L'objectif du séminaire est d'amener les acteurs présents (éditeurs de chaînes, journalistes, politiques) à débattre de la question du cordon sanitaire et ainsi mettre à plat les différentes interprétations qui en sont données. A terme ces réflexions serviront de cadre au Collège d'avis du CSA qui devra revoir le règlement relatif aux programmes de radio et télévision en période électorale. Il s'agit de proposer des perspectives et questions par rapport au fait de donner ou non la parole à l'extrême droite dans les médias. Plus précisément, il s'agit d'interroger la responsabilité sociale et éditoriale des médias en éclairant le rôle que les médias et les journalistes jouent concrètement dans le succès électoral de l'extrême droite (à partir d'une analyse discursive de la couverture médiatique des présidentielles françaises de 2002).

Continuous miniaturization has been at the heart of advances in modern semiconductor electronics. However, further scalability has seen its limits for conventional CMOS technology due to short channel effects. To further increase the performance for the 32 and 22 nm nodes, channel engineering introducing III-V materials may be necessary. Hence, epitaxial growth and processing strategies have to be developed which combine the high complexity of an MOCVD growth chamber with the requirements of the silicon industry. [less ▲]

We have deposited III-V alloys on 200 mm Si miscut wafers with an oxide pattern. The selective epitaxial growth (SEG) of GaAs in large windows defined by SiO2 lines on a thick strained-relaxed Ge buffer layer served as a test vehicle which allowed us to demonstrate the integration of a III-V material deposition process step in a Si manufacturing line using an industrial reactor. High quality GaAs layers with high wafer-scale thickness uniformity were achieved. In a subsequent step, SEG of InP was successfully performed on wafers with a 300 nm shallow trench isolation pattern. The seed layer morphology depended on the treatment of the Ge surface and on the growth temperature. The orientation of the trench with respect to the substrate miscut direction had an impact on the quality of the InP filling. Despite of the challenges, such an approach for the integration of III-V materials on Si substrates allowed us to obtain extended-defect-free epitaxial regions suitable for the fabrication of high-performance devices.

The 11-beta-hydroxysteroid dehydrogenase type 1 (11HSD1) enzyme promotes the local conversion from cortisone to cortisol, especially in the liver and the adipose tissue. It may play a role in the pathophysiology of abdominal obesity and the metabolic syndrome, both showing some similarities with the Cushing syndrome. Considering experimental results obtained in rodents, the inhibition of this enzyme could exert favourable metabolic effects, with significant reductions in plasma glucose, insulin resistance and dyslipidaemia. Synthetic inhibitors of 11HSD1 are currently in development with encouraging preliminary results, first in animals, and more recently in humans. Selective inhibitors of 11HSD1 may represent an innovative approach in the pharmacological management of obesity, metabolic syndrome and type 2 diabetes in a near future. [less ▲]

The research presented has been the result of the necessity of the growing performances of apiaries in Romania on the basis of increasing the level of fructification of the used resources. The most important activities that may be subject to the outsourcing process are: honey extraction, transport, the primary processing of apiarian products, packaging, bottling and labeling, marketing of bee products, financial-accounting records, the analysis the technical-economic projection, juridical assistance, promotion of apiarian products and services. The fructification of the mobility of certain activities in apiaries can be achieved by the following steps: the quantification of the level of usage of the available resources in the exploitation, the identification of alternatives to their own activities and the comparison of costs of alternatives with those of their own activities.

Dans un contexte global de perturbations anthropiques toujours croissantes des écosystèmes naturels et semi-naturels, l’unique conservation de ces écosystèmes ne suffit plus. La restauration écologique peut ainsi se révéler un complément essentiel à la conservation s.l. L’article consiste en une synthèse de la littérature scientifique dédiée aux concepts de la restauration écologique. Nous abordons la notion d’objectifs de la restauration notamment au travers de la référence écologique. Outre la définition d’objectifs clairs de restauration, la référence permet ensuite d’évaluer les efforts de restauration, par le biais d’indicateurs de suivi. Les indicateurs peuvent par ailleurs fournir des informations quant aux attributs de l’écosystème restauré et/ou la trajectoire écologique empruntée. Les éventuelles contraintes rencontrées par les espèces au travers de filtres à la restauration pourront être détectées et des mesures de compensation adéquates pourront être proposées. [less ▲]
