Sound modeling in coupled rooms (i.e., two acoustically coupled rooms separated by an open area) has attracted considerable attention in the past. However accurate and operational models are still needed, principally when three or more rooms are coupled. In recent papers, a diffusion equation-based model has been applied to unusual room shapes. For the coupled rooms geometry, this diffusion model has been validated successfully by comparison with the classical statistical theory in a parametrical study of the coupling parameters [Billon et al., J. Acoust. Soc. Am. 116, 2553 (2004)]. In the present work, the diffusion model results are validated by means of a comparison with experimental results, both in terms of sound attenuation and reverberation time. A comparison is also provided with results given by the statistical theory and a ray tracing program. For this purpose, experiments have been conducted in two coupled classrooms with two different sound source locations. The results show a very good agreement between the diffusion model and the experiments. Conversely, the statistical model is not valid for modeling accurately the sound field distribution and decay in both coupled rooms. At last, the diffusion model runs much faster than the ray tracing program. [less ▲]

Carbon monoxide total column amounts in the atmosphere were measured in the High Northern Hemisphere (30º-90º N, HNH) between January 1996 and December 2003 using Fourier Transform Infrared high resolution spectrometers installed at the NDSC (Network for Detection of Stratospheric Change) sites. A grating spectrometer of moderate resolution was employed for the same purpose at the Zvenigorod Research Station of the Institute of Atmospheric Physics near Moscow. CO mixing ratios were measured in the air samples obtained at the ground-level stations of the CMDL (Climate Modeling and Diagnostic Laboratory, NOAA) network. Total column CO amounts were measured from space by the Terra/MOPITT instrument between March, 2000, and December, 2003 (Edwards et al., 2004). Anomalies of monthly mean CO densities (related to a quiet period of 2000 - 2001) for different sites in the HNH were in agreement. This fact confirmed a good mixing of CO in the Northern Hemisphere on the montly basis that may be expected from a 1.5-2-month-long CO life-time. The data were integrated over the HNH reservoir (0-10 km in altitude and 30º-90º N in latitude) and the CO burden anomalies (in Tg) were analysed using a box model. Two CO sinks were taken into account: i) internal chemical removal in the reaction between CO and OH, and ii) transport of CO into the southertn part of the Northern hemisphere, where CO concentrations are usually lower. OH concentarations were taken from Spivakovsky et al. (2000). The air exchange through the 30º N boundary of the reservoir was estimated using the GEOS-CHEM model with a real meteorology of 1998 (Yurganov et al., 2004). The interannual variations of the sinks were neglected; a corresponding uncertainty in the retrieved source anomaly was estimated to be 20-30%. Since 1996 four years have been found to experience high CO emission of similar magnitude (1996, 1998, 2002, and 2003). During four years (1997, 1999, 2000, and 2001) the emissions were relatively low. Seasonal patterns of the emissions in active years were similar, maxima occured in July-August. However, in 2003 emissions in June-July were higher than in August. These semi-hemisphere averaged emission rates correlate with Siberian forest fire counts detected at night time by the ATSR radiometer of the ERS-2 satellite (R2 =0.51). The early peak of 2003 may be attributed to forest fires in Baikal region, Siberia. An inclusion of fire counts for other areas (Europe, North America) only worsen the correlation; this implies a decisive role of the Siberian fires for polluting the Northern Hemisphere troposphere (cf., Kasischke et al., 2005). It was estimated that the boreal forest fires during active years emit 30-60 Tg CO per month in July-August and 150-200 Tg annually. These emissions may be compared to industrial and transport pollution in the Northern Hemisphere estimated by Kasischke et al. (2005) as 290 Tg CO annually (i.e., 25 Tg monthly). [less ▲]

Locomotor activation is often reported to occur after a systemic administration of low doses of ethanol in most mouse strains, as for example outbred CD1 mice. However, in some strains of mice, such as the inbred C57BL/6J mice, and in rats, systemic injections of ethanol typically induce only a depression of the locomotor activity. Recently, Correa et al. (2003) showed that direct infusions of ethanol in the brain ventricles of rats induced locomotor stimulant effects. These authors suggested that some undefined peripheral effects of ethanol may mask its central stimulant effects when ethanol is administered intraperitoneally. The aim of the present study was to investigate the locomotor effects of either intraperitoneal and intracerebroventricular ethanol administrations in two strains of mice, outbred CD1 and inbred C57BL/6J, that are respectively characterized by the presence and absence of a locomotor stimulant response to ethanol. The results showed that ethanol at moderate and high doses induced locomotor depressant effects in C57BL/6J mice whatever the route of ethanol administration. In contrast, ethanol induced a biphasic effect on locomotor activity in CD1 mice with a stimulant response at low doses followed by a significant sedation. Such a response to ethanol was observed after both peripheral and central administrations of ethanol. The results of the present study demonstrate that the locomotor effects of ethanol in mice are not affected by the route of administration, i.e. peripheral or central. In these rodents, there is no evidence that unidentified peripheral effects of ethanol mask the stimulant ethanol effects. [less ▲]

Whereas human studies keep reporting evidence that acetaldehyde accumulation prevents alcohol drinking and alcoholism, animal studies support a rewarding rather than aversive role for acetaldehyde. In recent years, the reinforcing properties of acetaldehyde were demonstrated in various rodent strains and using different experimental methods. These results led to the hypothesis that acetaldehyde might be involved in the addictive properties of alcohol. The most recent experimental studies suggest that the apparent discrepancies between animal and human studies might be due to the localization of acetaldehyde accumulation. Whereas peripheral acetaldehyde accumulation leads to adverse reactions and prevents alcohol drinking, brain acetaldehyde is believed to be primarily reinforcing in both rodents and humans. In addition to its possible role in the reinforcing properties of alcohol, there is also evidence that acetaldehyde is involved in many other behavioral effects of ethanol. This presentation reviews the latest results about the behavioral properties of acetaldehyde. In both CD1 and C57BL/6J mice, acetaldehyde induces locomotor depressant, sedative and amnesic effects. These effects are observed when acetaldehyde is administered either in the periphery or directly into the brain. In contrast to previous studies in rats, we found no evidence of the stimulant effects of acetaldehyde over a wide range of doses, whether injected in the periphery or administered intracerebroventricularly. Additional studies with cyanamide, an aldehyde dehydrogenase inhibitor leading to peripheral and central acetaldehyde accumulations after ethanol administration, also confirm the role of acetaldehyde in the locomotor depressant, sedative and amnesic effects of ethanol. However, a key issue remains to be addressed in order to demonstrate the role of acetaldehyde in alcohol abuse. To date, it remains uncertain whether pharmacologically relevant acetaldehyde concentrations are formed in the brain after alcohol consumption in vivo. [less ▲]

This work presents a general framework for constitutive viscoelastic models in the finite deformation regime. The approach is qualified as variational since the constitutive updates consist of a minimization problem within each load increment. The set of internal variables is strain-based and uses a multiplicative decomposition of strain in elastic and viscous components. Spectral decomposition is explored in order to accommodate, into analytically tractable expressions, a wide set of specific models. Moreover, it is shown that, through appropriate choices of the constitutive potentials, the proposed formulation is able to reproduce results obtained elsewhere in the literature. Finally, numerical examples are included to illustrate the characteristics of the present formulation. (C) 2007 Elsevier B.V. All rights reserved. [less ▲]

The usual description of dust-modified ion-acoustic and dust-acoustic solitons in plasmas containing negative dust is in terms of Boltzmann distributions for the hotter species. In the dust-modified ion-acoustic regime, besides positive potential solitons, negative ones can also be generated, for non-Boltzmann as well as for Boltzmann electrons, subject to very mild conditions that were previously ignored or given for weakly nonlinear solutions only. In the dust-acoustic domain in plasmas with negatively charged dust, however, only negative potential solitons can occur, even when the lighter species have non-Boltzmann distributions [less ▲]

Using the fluid dynamic paradigm, we study acoustic solitons in a dusty plasma with two ion temperatures, using a polytropic equation of state. On the ion-acoustic timescale we consider a four-component plasma, with super-hot electrons and massive dust grains. We find existence regimes for both positive and negative potential solitons and double layers. For dust-acoustic solitons, we consider a three-component plasma, with no free electrons, and "super-hot" hot ions. This model supports both positive and negative potential solitons, unlike a dust-ion-electron plasma, that allows only negative solitons [less ▲]

One of the best-characterized actions of steroids is the regulation of brain areas involved in endocrine function and in the activation of reproductive behaviors in male and female vertebrates. Progress in the understanding of the mechanisms that control the expression of the eukaryotic genome by nuclear receptors has brought forward the importance of steroid receptor coactivators in mediating efficient gene transcription. However, little is know about the specific physiological requirements of these coactivators in vivo. In Japanese quail, testosterone treatment of castrated males restores the full copulatory behavior and increases the volume of the sexually dimorphic medial preoptic nucleus (POM) to the level observed in intact males [1]. Testosterone also affects a number of sexually dimorphic neurochemical characteristics such as the vasotocineric innervation of the septum and meadial preoptic nucleus [2]. The quail therefore provides an excellent model to study steroid-dependent sexual behavior and the associated neuroplasticity and should provide insights into the modulation of steroid action by steroid receptor coactivators. The present studies were focused on the steroid receptor co-activator-1 (SRC-1), which was already shown to be involved in the process of sexual differentiation of brain and behavior in rats [3]. We first amplified by RT-PCR from quail brains a 3,411bp fragment highly homologous with the chicken (94.5%) and mammalian (70%) SRC-1 and designed digoxigenin-labeled oligonucleotides for in situ hybridization. A broad distribution of SRC-1 transcripts was observed throughout the male quail brain. A particularly dense coactivator expression was observed in limbic (e.g. POM, nucleus striae terminalis) and mesencephalic (e.g. substantia grisea centralis) nuclei associated with the control of male sexual behavior [4]. Because male and female quail exhibit a very pronounced sexual dimorphism in the steroid-dependent mechanisms that activate male-typical copulatory behavior, we investigated the potential role of SRC-1 in the sexually differentiated responses to steroids by quantifiying the SRC-1 mRNA by real time quantitative polymerase chain reaction (qPCR) and the corresponding protein by western blot (WB). Contrary to previous results, which had identified a higher SRC-1 mRNA expression in the POM of males compared to females [4], we found in two separate experiments that sexually mature females had higher concentrations of SRC-1 in the preoptic area-hypothalamus (HPOA) compared to males. Additional studies should be carried out to identify the origins of this discrepancy but seasonality and time of the day when brains were collected are potentially involved. We also quantified the SRC-1 mRNA and protein in the preoptic area-hypothalamus (HPOA) of castrated males treated or not with testosterone. SRC-1 mRNA was increased by testosterone in two independent experiments but not in a third one. This difference is likely due to the differential manipulations of the birds during these experiments. Birds had been repeatedly handled to test their sexual behavior in the first experiment and we showed that stress tends to decrease the coactivator expression in the male HPOA. This interpretation is strengthened by recent work in rats indicating that stress regulates SRC-1 expression in hypothalamus and hippocampus [5]. More surprisingly, we found a significant correlation between the expression of SRC-1 and the time of the day when birds were killed in the optic lobes, hippocampus and hindbrain. The expression of SRC-1 in the optic lobes increased throughout the day, independently of sex, testosterone treatment or stress. In the hippocampus and hindbrain, the coactivator concentration varied in opposite directions during the morning and afternoon and reached respectively its lowest or highest concentration around the middle of the day, here again independently of sex, stress and hormonal treatment. Together, these data support the idea that SRC-1 is not constitutively expressed but regulated by steroids, stress and possibly other unidentified factors. Differential controls also appear to take place in specific brain nuclei and these differential controls should be further analyzed by immunohistochemistry and in situ hybridization. A second part of our work was dedicated to the study of the physiological significance of SRC-1 whith the use of daily intra-cerebroventricular injections of modified antisense (AS) oligonucleotides (Locked nucleic acid LNA) to disrupt SRC-1 expression in the POM. AS injections significantly reduced the expression of male copulatory behavior in response to exogenous testosterone compared to control animals (Ctrl group) that received the vehicle alone or scrambled (SC) oligonucleotides. Moreover, sexual behavior was restored and even enhanced within 48 hours after interruption of AS injection (ASSC group). Western blot analysis confirmed the decrease of SRC-1 expression in AS animals and demonstrated an over-expression of the coactivator in ASSC animals. The effects of SRC-1 knock down on behavior was related to a reduced POM volume defined by Nissl-staining and aromatase immunohistochemistry. The aromatase index, indicative of the relative amount of aromatase in the POM as well as the vasotocinergic innervation of this nucleus were higher in the Ctrl group. Taken together, these findings indicate that SRC-1 functions as a critical regulatory molecule in the brain to modulate steroid-dependent gene transcription and behavior. The study of the modulation of nuclear receptors activity by different co-regulatory proteins is still in its infancy. Abnormal co-activator expression or function is currently being linked to some endocrine/neurological disorders in humans and it is thus critical to understand how co-activator expression and function are controlled in the developing as well as in the adult brain.

Steroid receptor coactivators such as SRC-1 significantly modulate the expression of steroid-dependent physiological and behavioral characteristics in birds and mammals. Changes in coactivator protein expression are therefore likely to affect receptor-mediated transcriptional activity. We previously reported a tissue-dependent regulation of SRC-1 mRNA and protein levels by sex, stress and testosterone in the quail brain. In addition, SRC-1 expression has been shown to vary in mammals during development or in adulthood as a function of seasonal variation in photoperiod. We describe here tissue-specific changes of SRC-1 expression over the course of the day in quail. SRC-1 protein quantified by Western blots in the hindbrain gradually increased in the morning, reached a peak around midday and declined significantly in the afternoon. In contrast, SRC-1 protein levels in the optic lobes progressively decreased in the morning to reach their lowest values around midday before rising in the afternoon. The coactivator concentration in the hippocampus exhibited a progressive increase throughout the day. No change in the SRC-1 protein was detected during the day in the preoptic area and in the cerebellum. The functional significance and the mechanisms of regulation underlying such changes remain to be understood. An important unresolved question is whether this diurnal variation in SRC-1 expression is circadian in nature and if so if SRC-1 is an active player linked to clock genes in the generation of circadian rhythms or if the observed changes in SRC-1 expression are a consequence of the rhythms generated by these genes.

We consider random matrix models for the thermodynamic competition between chiral symmetry breaking and diquark condensation in QCD at finite temperature and finite baryon density. The models produce mean field phase diagrams whose topology depends solely on the global symmetries of the theory. We discuss the block structure of the interactions that is imposed by chiral, spin, and color degrees of freedom and comment on the treatment of density and temperature effects. Extension of the coupling parameters to a larger class of theories allows us to investigate the robustness of the phase topology with respect to variations in the dynamics of the interactions. We briefly study the phase structure as a function of coupling parameters and the number of colors. [less ▲]
