description Publicationkeyboard_double_arrow_right Article 1992 FrancePublisher:Elsevier BV Authors: Guillou, A.; Choubert, Georges; DE LA NOUE, J.;Guillou, A.; Choubert, Georges; DE LA NOUE, J.;Abstract 1. 1. Using one force-fed meal, eight mature female rainbow trout received [14C]astaxanthin ([14C]Ax) with [3H]canthaxanthin ([3H]Cx; N = 3) or with [3H]zeaxanthin ([3H]Zx; N = 5). 2. 2. Approximately 200 μl of blood were collected via caudal puncture every 24 hr for 4 days. After 96 hr, the fish were killed and pyloric caeca (P.C.) from the duodenal intestine (D.I.) section, ileal intestine (I.I.), and posterior intestine (P.I.) were dissected out. 3. 3. In the blood, Ax levels were higher than Cx followed by Zx levels. 4. 4. This corresponds to their respective absorption by the trout as was confirmed by their relative concentrations in P.C., I.I. and P.I. 5. 5. However, blood clearance was similar for all three compounds. [14C]Phoenicoxanthin ([14C]Px) was detected as a reduced metabolite of [14C]Ax in all gut sections.

Significant numbers of binding sites for the radioiodinated, 27-amino-acid form of PACAP were detected as early as E14 in the neuroepithelia of the metencephalon and the myelencephalon. From E14 to E21, the density of binding sites in the germinative areas increased by 3- to 5-fold. From birth to P12, the density of binding sites gradually declined in all neuroepithelia except in the external granule cell layer of the cerebellum, where the level of binding sites remained high during the first postnatal weeks. Only low to moderate densities of PACAP binding sites were found in regions other than the germinative areas, with the exception of the internal granule cell layer of the cerebellum, which contained a high density of sites. The localization of PACAP receptor mRNAs was investigated by in situ hybridization using [(35)S] uridine triphosphate-specific riboprobes. The evolution of the distribution of PAC1-R and VPAC1-R mRNAs was very similar to that of PACAP binding sites, the concentration of VPAC1-R mRNA being much lower than that of PAC1-R mRNA. In contrast, intense expression of VPAC2-R mRNA was observed in brain regions other than germinative areas, such as the suprachiasmatic, ventral thalamic, and dorsolateral geniculate nuclei. The discrete localization of PACAP binding sites as well as PAC1-R and VPAC1-R mRNAs in neuroepithelia during embryonic life and postnatal development strongly suggests that PACAP, acting through PAC1-R and/or VPAC1-R, may play a crucial role in the regulation of neurogenesis in the rat brain.

The paper describes our research process resulting in the documentation of 300 plant word names and phrases, starting with 135 plants with names and words in Kwak̓wala that had been documented between the late 19th and early 20th century by Franz Boas and George Hunt, subsequently added to and enriched by community members and academics. An audio-visual dictionary of these plant names and associated phrases is now available through the FirstVoices web portal (http://bit.ly/LDC_FirstVoices). The corresponding author initiated the work and then further developed the research in collaboration with Kwakwa̱ka̱’wakw fluent speakers, linguists, biologists, and the U’mista Cultural Society. The project has stimulated interest among community members who provided valuable feedback on the different ways in which this research can be further accessed and then delivered. The paper concludes with some structured reflections on how to proceed in community-led research projects such as this. The authors see further opportunity for continued cross-disciplinary and community-based research.

In designing mobile educational games, our distributed team took advantage of diverse talent pools and differing perspectives to drive forward a core vision of our overarching design targets. Our strategies included intense design workshops, use of online meeting rooms, paper and software prototyping as group activities, and dissemination of prototypes to other teams for refinement and repurposing. Our group showed strong activity at the university-centered nodes with periods of highly effective dissemination between these nodes and to outside groups; we used workshop invitations to gather new ideas and perspectives , to refine the vision, to forge inter-project links, and to stay current on what was happening in other networks. Several important aspects of our final deliverables came from loosely associated network members who engaged via collaborative design exercises in workshops, emphasizing the need to bring the network together and the importance of outside influences as ideas evolve. Our final deliverables demonstrate how our network both maintained a consistent vision and incorporated new ideas in the design of mobile augmented reality games, how our network experienced a new open approach of knowledge and technology sharing towards the sustainability of our research outcomes.

A multiple-baseline design across individuals was employed. Participants spent 10 minutes, four or five times per week, practising an audio-tapedimagery program, which was consisted of 28 sessions. Measures of imagery vividness were obtained from the Vividness of Movement lmagery Questionnaire during the baseline and treatment phases. Results showed significant improvementsin vividness scores on both the external and internal imagery perspective scales, with increases in the range of 15.8 % to 32.3 % from the baseline to thetreatment phase. The findings are discussed with regard to individual cases and Lang's (1979) Bio-informational Theory.

The variability in brain morphology and the difference in intensity characteristics due to imaging sequences make the development of a general purpose brain extraction algorithm challenging. To address this issue, we propose a new robust method (BEaST) dedicated to produce consistent and accurate brain extraction. This method is based on nonlocal segmentation embedded in a multi-resolution framework. A library of 80 priors is semi-automatically constructed from the NIH-sponsored MRI study of normal brain development, the International Consortium for Brain Mapping, and the Alzheimer's Disease Neuroimaging Initiative databases. In testing, a mean Dice similarity coefficient of 0.9834 ± 0.0053 was obtained when performing leave-one-out cross validation selecting only 20 priors from the library. Validation using the online Segmentation Validation Engine resulted in a top ranking position with a mean Dice coefficient of 0.9781 ± 0.0047. Robustness of BEaST is demonstrated on all baseline ADNI data, resulting in a very low failure rate. The segmentation accuracy of the method is better than two widely used publicly available methods and recent state-of-the-art hybrid approaches. BEaST provides results comparable to a recent label fusion approach, while being 40 times faster and requiring a much smaller library of priors. Data collection and sharing for this project was funded by the Alzheimer's Disease Neuroimaging Initiative (ADNI) (National Institutes of Health Grant U01 AG024904).

Abstract Objects occupy space. How does the brain represent the spatial location of objects? Retinotopic early visual cortex has precise location information but can only segment simple objects. On the other hand, higher visual areas can resolve complex objects but only have coarse location information. Thus coarse location of complex objects might be represented by either (a) feedback from higher areas to early retinotopic areas or (b) coarse position encoding in higher areas. We tested these alternatives by presenting various kinds of first- (edge-defined) and second-order (texture) objects. We applied multivariate classifiers to the pattern of EEG amplitudes across the scalp at a range of time points to trace the temporal dynamics of coarse location representation. For edge-defined objects, peak classification performance was high and early and thus attributable to the retinotopic layout of early visual cortex. For texture objects, it was low and late. Crucially, despite these differences in peak performance and timing, training a classifier on one object and testing it on others revealed that the topography at peak performance was the same for both first- and second-order objects. That is, the same location information, encoded by early visual areas, was available for both edge-defined and texture objects at different time points. These results indicate that locations of complex objects such as textures, although not represented in the bottom–up sweep, are encoded later by neural patterns resembling the bottom–up ones. We conclude that feedback mechanisms play an important role in coarse location representation of complex objects.

J.; Orlov, A.; Badger, C. L.; Griffiths, P. T.; Cox, R. A.; Lambert, R. M.;Abstract. The hygroscopicity of mineral aerosol samples has been examined by three independent methods: diffuse reflectance infrared Fourier transform spectroscopy, thermogravimetric analysis and differential mobility analysis. All three methods allow an evaluation of the water coverage of two samples, CaCO3 and Arizona Test dust, as a function of relative humidity. For the first time, a correlation between absolute gravimetric measurements and the other two (indirect) methods has been established. Water uptake isotherms were reliably determined for both solids which at 298 K and 80% relative humidity exhibited similar coverages of ~4 monolayers. However, the behaviour at low relative humidity was markedly different in the two cases, with Arizona Test Dust showing a substantially higher affinity for water in the contact layer. This is understandable in terms of the chemical composition of these two materials. The mobility analysis results are in good accord with field observations and with our own spectroscopic and gravimetric measurements. These findings are of value for an improved understanding of atmospheric chemical processes.

We select five stations localised around the Mediterranean and the Black seas: Tipaza (252 kHz, 02°28’E, 36°33’N, Algeria), Roumoules (216 kHz, 06°08’E, 43°47’N, Monte Carlo), Polatli (180 kHz, 32°25’E, 39°45’N, Turkey), Nadour (171 kHz, 02°55’W, 35°02’N, Morocco) and Brasov (153 kHz, 25°36’E,45°40’, Romania). The detection of the LF transmitter signals by DEMETER micro-satellite is found to depend on the radiated power, the emitted frequency, and the orbit paths with regard to the location of the stations. This leads us to characterise the reception condition of the LF signals and to define time intervals where the detection probability is high. We show that LF signal are regularly recorded, each 12 days, when the satellite is above the broadcasting station. The signal intensity levels are principally significant during the solar activity. Hence we find that the solar and the geomagnetic activities are slightly correlated to the maxima of LF signal as recorded by DEMETER. Also we note a drop of the intensity level several days before the occurrence of earthquakes in/around the Mediterranean and Black seas.

Using one force-fed meal, eight mature female rainbow trout received [14C]astaxanthin ([14C]Ax) with [3H]canthaxanthin ([3H]Cx; N = 3) or with [3H]zeaxanthin ([3H]Zx; N = 5). 2. 2. Approximately 200 μl of blood were collected via caudal puncture every 24 hr for 4 days. After 96 hr, the fish were killed and pyloric caeca (P.C.) from the duodenal intestine (D.I.) section, ileal intestine (I.I.), and posterior intestine (P.I.) were dissected out. 3. 3. In the blood, Ax levels were higher than Cx followed by Zx levels. 4. 4. This corresponds to their respective absorption by the trout as was confirmed by their relative concentrations in P.C., I.I. and P.I. 5. 5. However, blood clearance was similar for all three compounds. [14C]Phoenicoxanthin ([14C]Px) was detected as a reduced metabolite of [14C]Ax in all gut sections.

Significant numbers of binding sites for the radioiodinated, 27-amino-acid form of PACAP were detected as early as E14 in the neuroepithelia of the metencephalon and the myelencephalon. From E14 to E21, the density of binding sites in the germinative areas increased by 3- to 5-fold. From birth to P12, the density of binding sites gradually declined in all neuroepithelia except in the external granule cell layer of the cerebellum, where the level of binding sites remained high during the first postnatal weeks. Only low to moderate densities of PACAP binding sites were found in regions other than the germinative areas, with the exception of the internal granule cell layer of the cerebellum, which contained a high density of sites. The localization of PACAP receptor mRNAs was investigated by in situ hybridization using [(35)S] uridine triphosphate-specific riboprobes. The evolution of the distribution of PAC1-R and VPAC1-R mRNAs was very similar to that of PACAP binding sites, the concentration of VPAC1-R mRNA being much lower than that of PAC1-R mRNA. In contrast, intense expression of VPAC2-R mRNA was observed in brain regions other than germinative areas, such as the suprachiasmatic, ventral thalamic, and dorsolateral geniculate nuclei. The discrete localization of PACAP binding sites as well as PAC1-R and VPAC1-R mRNAs in neuroepithelia during embryonic life and postnatal development strongly suggests that PACAP, acting through PAC1-R and/or VPAC1-R, may play a crucial role in the regulation of neurogenesis in the rat brain.

The paper describes our research process resulting in the documentation of 300 plant word names and phrases, starting with 135 plants with names and words in Kwak̓wala that had been documented between the late 19th and early 20th century by Franz Boas and George Hunt, subsequently added to and enriched by community members and academics. An audio-visual dictionary of these plant names and associated phrases is now available through the FirstVoices web portal (http://bit.ly/LDC_FirstVoices). The corresponding author initiated the work and then further developed the research in collaboration with Kwakwa̱ka̱’wakw fluent speakers, linguists, biologists, and the U’mista Cultural Society. The project has stimulated interest among community members who provided valuable feedback on the different ways in which this research can be further accessed and then delivered. The paper concludes with some structured reflections on how to proceed in community-led research projects such as this. The authors see further opportunity for continued cross-disciplinary and community-based research.

In designing mobile educational games, our distributed team took advantage of diverse talent pools and differing perspectives to drive forward a core vision of our overarching design targets. Our strategies included intense design workshops, use of online meeting rooms, paper and software prototyping as group activities, and dissemination of prototypes to other teams for refinement and repurposing. Our group showed strong activity at the university-centered nodes with periods of highly effective dissemination between these nodes and to outside groups; we used workshop invitations to gather new ideas and perspectives , to refine the vision, to forge inter-project links, and to stay current on what was happening in other networks. Several important aspects of our final deliverables came from loosely associated network members who engaged via collaborative design exercises in workshops, emphasizing the need to bring the network together and the importance of outside influences as ideas evolve. Our final deliverables demonstrate how our network both maintained a consistent vision and incorporated new ideas in the design of mobile augmented reality games, how our network experienced a new open approach of knowledge and technology sharing towards the sustainability of our research outcomes.

A multiple-baseline design across individuals was employed. Participants spent 10 minutes, four or five times per week, practising an audio-tapedimagery program, which was consisted of 28 sessions. Measures of imagery vividness were obtained from the Vividness of Movement lmagery Questionnaire during the baseline and treatment phases. Results showed significant improvementsin vividness scores on both the external and internal imagery perspective scales, with increases in the range of 15.8 % to 32.3 % from the baseline to thetreatment phase. The findings are discussed with regard to individual cases and Lang's (1979) Bio-informational Theory.

The variability in brain morphology and the difference in intensity characteristics due to imaging sequences make the development of a general purpose brain extraction algorithm challenging. To address this issue, we propose a new robust method (BEaST) dedicated to produce consistent and accurate brain extraction. This method is based on nonlocal segmentation embedded in a multi-resolution framework. A library of 80 priors is semi-automatically constructed from the NIH-sponsored MRI study of normal brain development, the International Consortium for Brain Mapping, and the Alzheimer's Disease Neuroimaging Initiative databases. In testing, a mean Dice similarity coefficient of 0.9834 ± 0.0053 was obtained when performing leave-one-out cross validation selecting only 20 priors from the library. Validation using the online Segmentation Validation Engine resulted in a top ranking position with a mean Dice coefficient of 0.9781 ± 0.0047. Robustness of BEaST is demonstrated on all baseline ADNI data, resulting in a very low failure rate. The segmentation accuracy of the method is better than two widely used publicly available methods and recent state-of-the-art hybrid approaches. BEaST provides results comparable to a recent label fusion approach, while being 40 times faster and requiring a much smaller library of priors. Data collection and sharing for this project was funded by the Alzheimer's Disease Neuroimaging Initiative (ADNI) (National Institutes of Health Grant U01 AG024904).

Abstract Objects occupy space. How does the brain represent the spatial location of objects? Retinotopic early visual cortex has precise location information but can only segment simple objects. On the other hand, higher visual areas can resolve complex objects but only have coarse location information. Thus coarse location of complex objects might be represented by either (a) feedback from higher areas to early retinotopic areas or (b) coarse position encoding in higher areas. We tested these alternatives by presenting various kinds of first- (edge-defined) and second-order (texture) objects. We applied multivariate classifiers to the pattern of EEG amplitudes across the scalp at a range of time points to trace the temporal dynamics of coarse location representation. For edge-defined objects, peak classification performance was high and early and thus attributable to the retinotopic layout of early visual cortex. For texture objects, it was low and late. Crucially, despite these differences in peak performance and timing, training a classifier on one object and testing it on others revealed that the topography at peak performance was the same for both first- and second-order objects. That is, the same location information, encoded by early visual areas, was available for both edge-defined and texture objects at different time points. These results indicate that locations of complex objects such as textures, although not represented in the bottom–up sweep, are encoded later by neural patterns resembling the bottom–up ones. We conclude that feedback mechanisms play an important role in coarse location representation of complex objects.

For the first time, a correlation between absolute gravimetric measurements and the other two (indirect) methods has been established. Water uptake isotherms were reliably determined for both solids which at 298 K and 80% relative humidity exhibited similar coverages of ~4 monolayers. However, the behaviour at low relative humidity was markedly different in the two cases, with Arizona Test Dust showing a substantially higher affinity for water in the contact layer. This is understandable in terms of the chemical composition of these two materials. The mobility analysis results are in good accord with field observations and with our own spectroscopic and gravimetric measurements. These findings are of value for an improved understanding of atmospheric chemical processes.

M.; Besser, Bruno; Wolbang, Daniel; Prattes, Gustav; Eichelberger, Hans; Stangl, Günter,; Parrot, Michel; Schwingenschuh, Konrad;International audience; We analyse the flux density variation associated to low frequency (LF) broadcasting transmitters observed by the ICE electric field experiment onboard DEMETER micro-satellite, observed from 01st Jan. to 09th Dec. 2010. We select five stations localised around the Mediterranean and the Black seas: Tipaza (252 kHz, 02°28’E, 36°33’N, Algeria), Roumoules (216 kHz, 06°08’E, 43°47’N, Monte Carlo), Polatli (180 kHz, 32°25’E, 39°45’N, Turkey), Nadour (171 kHz, 02°55’W, 35°02’N, Morocco) and Brasov (153 kHz, 25°36’E,45°40’, Romania). The detection of the LF transmitter signals by DEMETER micro-satellite is found to depend on the radiated power, the emitted frequency, and the orbit paths with regard to the location of the stations. This leads us to characterise the reception condition of the LF signals and to define time intervals where the detection probability is high. We show that LF signal are regularly recorded, each 12 days, when the satellite is above the broadcasting station. The signal intensity levels are principally significant during the solar activity. Hence we find that the solar and the geomagnetic activities are slightly correlated to the maxima of LF signal as recorded by DEMETER. Also we note a drop of the intensity level several days before the occurrence of earthquakes in/around the Mediterranean and Black seas.
