Our goal is to fuse multimodality imagery to enhance image-guided neurosurgery. Images that need to be fused must be registered. Registration becomes a challenge when the imaged object deforms between the times the images to be fused are taken. This is the case when “brain-shift” occurs. We begin by describing our strategy for nonrigid registration via finite-element methods. Then, we independently discuss an image fusion strategy based on a model of the human visual system. We illustrate the operation of many components of the registration system and the operation of the fusion system. [less ▲]

The paper analyses the ability of thin-film tactile sensors in providing information during static compression tests of ‘Jonagold’ apples (Malus pumila) of different ripeness stages. Such sensors are able to measure the contact surface and the interfacial pressure distribution during compression of fruits, this latter being characterised by suitable mathematical parameters. Results of compression tests between two flat steel plates are presented. The differentiated evolution of the pressure distribution according to the fruit maturity is pointed out. Ability of the sensor in evaluating the firmness is also discussed. [less ▲]

It has been postulated that a number of central effects of ethanol are mediated through the action of its first metabolite, acetaldehyde. In particular, acetaldehyde might be involved in the anxiolytic and hedonic effects of ethanol and is therefore believed to play an important role in alcohol abuse. In agreement with this assumption, previous studies indicated that acetaldehyde is mainly reinforcing in rats, which have been shown to readily self-administer acetaldehyde both peripherally and centrally. However, the hedonic effects of acetaldehyde have never been tested in mice, and the possible amnesic and anxiolytic effects of acetaldehyde remain to be elucidated. Therefore, the present studies were aimed at characterizing the anxiolytic, hedonic and amnesic effects of acetaldehyde after its acute peripheral administration to C57BL/6J mice. The effects of intraperitoneal acetaldehyde (0-300 mg/kg) injections were assessed in several classical behavioral tests. The anxiolytic effects were tested with the elevated plus maze, the hedonic effects with the place conditioning procedure and the amnesic effects with the passive avoidance apparatus. Our results show that acetaldehyde dose-dependently altered memory consolidation as evidenced by a reduced performance in the passive avoidance test when acetaldehyde was injected immediately after training at doses between 100 and 300 mg/kg. The elevated plus-maze showed that acetaldehyde, in contrast to ethanol, does not possess anxiolytic properties. Finally, the results of the place conditioning experiment confirmed that acetaldehyde displays significant hedonic properties. The present results add further support to the role of acetaldehyde in ethanol amnesic and hedonic effects but interestingly suggest that acetaldehyde is not involved in ethanol anxiolytic effects.

Acetaldehyde, the first ethanol metabolite, was recently suggested to play a major role in many behavioral effects of ethanol. However, no studies have directly investigated the behavioral effects of acetaldehyde after acute administration. Therefore, the aim of the present study was to characterize the locomotor, hypnotic and ataxic effects of acetaldehyde in C57BL/6J mice. Various acetaldehyde doses (0-300 mg/kg) were injected intraperitoneally and their effects were investigated with several classical behavioral tests. The locomotor effects of acetaldehyde were measured in standard activity boxes. In addition, the loss of righting reflex was used to assess the hypnotic effects of acetaldehyde. Finally, the ataxic effects of acetaldehyde were studied with the horizontal wire test. The results show that acetaldehyde induced a significant hypolocomotor effect at 170 mg/kg and higher doses. In addition, the hypnotic effects of acetaldehyde were evidenced by a loss of righting reflex in doses between 170 and 300 mg/kg. However, the locomotor and hypnotic effects of acetaldehyde were very brief relative to what is observed after ethanol administration. After 170 mg/kg acetaldehyde, normal activity was recovered in less than 30 minutes and the loss of righting reflex lasted only an average of 6.14 ± 1.29 minutes after the administration of 300 mg/kg acetaldehyde, the highest testable dose before lethality. Ataxic effects were observed with lower doses that did not significantly affect locomotor activity. These results show that acetaldehyde, like ethanol, possesses sedative, hypnotic and ataxic properties and therefore indicate that the first product of ethanol metabolism might be involved in these ethanol effects.

We propose TCP-L, an improved version of TCP, equipped with a learning algorithm whose purpose is to avoid probing for additional bandwidth when the network conditions are known to be unfavourable. TCP-L learns the relationship between its current (average) one-trip delay and its current window size when congestion occurs, leading to packet loss. After the learning phase, TCP-L will only probe for bandwidth by increasing its window if, under the current network conditions (measured by the one-trip delay), this inflated window has not previously created congestion. Simulations show that after the learning phase, TCP-L reaches a much more stable throughput, while remaining TCP-friendly, which makes it usable for a larger class of applications, including some multimedia applications that will benefit from that stability. TCP-L is a simple backward compatible extension of TCP which can thus be deployed progressively. We show that there is a benefit for the Internet to deploy TCP-L, because the overall traffic becomes smoother when the proportion of TCP-L flows increases. Finally, our learning component can also be easily embedded in other unicast or multicast transport protocols. [less ▲]

This paper presents a constitutive law based on taylor's model implemented in our non-linear finite element code LAGAMINE. The yield locus is only locally described and a particular interpolation method has been developed. This local yield locus model uses a discrete representation of the material's texture. The interpolation method is presented and a deep-drawing application is simulated in order to show up the influence of the texture evolution during forming processes. [less ▲]

Adapté à des climats rudes et des hivers froids et enneigés, le tétras lyre (Petit coq de bruyère Tetrao tetrix. Oiseau Galliforme) a une répartition géographique boréo-montagnarde. Les résultats d'une modélisation statistique originale ont montré que les T° minimales et les précipitations locales, enregistrées au cours de certaines périodes cruciales du cycle de vie de l'oiseau, interviennent comme variables explicatives pour reproduire les fluctuations des effectifs annuels recensés depuis 20 et 30 ans en Belgique, Allemagne, Grande-Bretagne et Pays-Bas. Des résultats communs hautement significatifs confirment le rôle négatif des hivers doux et des précipitations pendant la période de reproduction (couvaison et premières semaines des poussins), et le rôle positif des températures chaudes pendant la période d'éclosion des jeunes. La qualité des résultats obtenus, la nature des variables météorologiques impliquées et le contexte de réchauffement climatique global nous ont fait chercher d'éventuelles tendances parmi les variables utilisées. Elles se sont révélées significatives en comparant l'évolution des moyennes standard de températures minimales et de précipitations mensuelles. Les différences dans les précipitations ont d'importantes répercussions biologiques car elles peuvent effectivement nuire à la reproduction et l'hivernage de l'espèce étudiée. Le réchauffement semble donc bien intervenir dans le déclin des populations à long terme, même si le tétras souffre du changement climatique en plus des atteintes anthropiques à son environnement et à sa tranquillité. Pour pallier aux défauts du climat, le gestionnaire prendra des décisions qui améliorent à tous points de vue la qualité, la capacité d'accueil et la tranquillité de l'habitat préféré de cet oiseau afin de favoriser sa conservation à court terme.

The aim of this experiment is to examine how recollection and familiarity change over time and whether there is a qualitative difference between familiar items that were previously recollected and items that have always been familiar. It might be that, when an item is initially recollected and becomes just familiar after a delay, this form of familiarity is actually a weak and partial recollection, qualitatively different from mere familiarity. To address this issue, a task have been developed in which, at study, participants encoded two series of 100 pictures representing scenes under respectively shallow and deep encoding conditions. Memory for these pictures was tested by means of a yes-no recognition test. Recognised items were classified as recollected or as familiar. Half of the pictures from each encoding condition were tested after 10 minutes and the other half were tested after 2 days. The results indicated that recollection decreased after 2 days while familiarity increased (deep encoding condition) or did not change (shallow encoding condition). This suggests that, among the items judged as familiar after 2 days, some items would have been recollected after 10 minutes and some were initially already familiar. Because deep encoding produced a higher proportion of recollection at the 10-minute interval, the proportion of recollection-changed-into-familiarity responses should be greater in this condition than in the shallow encoding condition. Whether there is a qualitative difference between these responses and pure familiarity responses should be explored in a fMRI experiment. [less ▲]

The structural and magnetic properties of the granular iron nitride-alumina composite materials: (FexN)(0.2)(Al2O3)(0.8) and (FexN)(0.6)(Al2O3)(0.4), fabricated using high-energy ball milling have been determined by using X-ray diffraction, Mossbauer spectroscopy, and magnetization measurements. The Mossbauer spectra, fit with a distribution of hyperfine fields between zero and 40 T. indicate that the weighted average field decreases with increasing milling time. The isomer shift increases with milling time because of a reduced iron 4s-electron density at the grain boundaries. Coercive fields as high as 325 and 110 Oe are obtained for (FexN)(0.2)(Al2O3)(0.8) at 5 and 300 K, respectively; the increase in the coercive field upon cooling indicates the presence of superparamagnetic particles. The coercive field increases with milling time because of the reduced particle size. The decrease in the magnetization results from the increase in both the superparamagnetic fraction and the concentration of surface defects with increased milling time. [less ▲]

Songbirds have developed a specialized, steroid-dependent telencephalic vocal control system for the production of learned vocalization. Recent progress in the study of the mechanisms by which steroid receptors act on the eukaryotic genome has highlighted the role of a newly discovered protein family, the Nuclear Receptor Coactivators. More specifically, the CREB-binding protein (CBP) and the Steroid Receptor Coactivator-1 (SRC-1) have been shown to be actively involved in mediating steroid hormone action in the developing rat brain. The distribution of the coactivator SRC-1 was analyzed in canaries by in situ hybridization. A very broad but heterogeneous distribution of the transcript was observed, mainly in steroid-sensitive areas of the hypothalamus, the song control system and several catecholaminergic areas. The presence of SRC-1 in these regions was also confirmed by immunocytochemistry. A similar very high concentration of the coactivator CBP protein was also found in steroid-sensitive areas of the hypothalamus and in the song system. Sex differences in SRC-1 mRNA concentration were detected in HVC and in area X. Moreover, preliminary data obtained independently in starlings (CBP) and in quail (SRC-1) suggest that the expression of coactivators is regulated by steroids as well as by photoperiod. The presence of these steroid receptor coactivators in the telencephalic song control nuclei and in catecholaminergic cell groups that innervate the song system and their possible regulation by photoperiod and/or steroids support the idea that SRC-1 and CBP could play an important role in the control of singing behavior by modulating estrogen and androgen receptor action.

Since the Seventies, a séries of phenomena developed in non carbonated silicated rocks question the traditional vision of karst. The term of karst is used in the meaning of "any feature of the classical karst morphology (caves, sink-holes, lapiaz...) where dissolution plays the main genetic action and this in any kind of rocks". The cave of Guéssédoundou illustrâtes a karst in métagabbros. It opens at the top of a small hill, in a dépression twenty meters long and three to four meters deep. The walls of this dépression are subvertical and the bottom is partially occupied by angular pluridecimetric blocks. The cave is opened on several meters in the southern side of the dépression and is prolonged in the form of too narrow conduits to be explore. The bedrock is a metagabbro with fine grains, slightly weathered, crossed by decimetric quartzose veins. Gabbroïc texture is preserved, as well as part of magmatic plagioclases. The remainder is transformed into a mixture of white feldspar and clinozoisite. Pyroxene are pseudomorphosed in actinote and chlorite. The site dépression was created along a N 10° shear zone where rocks suffered important fracturation and fluid transfers, as shown by its silification and ferruginisation.. Moreover, a East-West schistosity, former to shearing, structures the gabbro. The présence of angular blocks of variable size and the absence of human activity trace on the site show that the dépression was formed naturally by collapse of the roof of a more vast cavity whose current cave would be the visible residual prolongation. The absence of flow traces and mechanical abrasion means that this cavity is due only to chemical érosion . At the cave entry and on the subvertical walls of the dépression were formed by alveoli a few centimètres to a few décimètres in diameter. Thèse alveoli of wall are known in other lithologies, in particular in limestones. The absence of salts within the rock draws aside a formation by sait weathering. The smooth aspect and non fractured walls of the cells cannot resuit from a corrosion to a fracturing node. The closed aspect of the dépression and the absence of flow trace eliminate the assumptions from formation by water swirls or eolisation. The genesis of the cave must be earlier to the installation of a weathering cover since the rock is little deteriorated and the alveoli are not developed on a quite particular level which would correspond to a précise pedogenic horizon. Only a generalized dissolution of the métagabbros, in relation to a slow solution circulation, being carried out with the favour of the fracturing plans of the shearing zone makes it possible to explain the formation of the alveoli. The inversion of relief results from a weaker érosion of the rocks made more résistant to this place by the quartz seam mainstay and by the ferruginisation along the shearing zone. In the other hand, the crushed rocks, become porous, drained the infiltrations of meteoric water, facilitating the dissolution processes. The study of the site of Guéssédoundou shows that karstic phenomena can also exist in silico-aluminous formations of crystalline rocks [less ▲]
