Invariable biomass-specific primary production of taxonomically discrete picoeukaryote groups across the Atlantic Ocean
No full textOceanic photosynthetic picoeukaryotes (< 3 µm) are responsible for > 40% of total primary production at low latitudes such as the North-Eastern tropical Atlantic. In the world ocean, warmed by climate changes, the expected gradual shift towards smaller primary producers could render the role of photosynthetic picoeukaryotes even more important than they are today. Little is still known, however, about how the taxonomic composition of this highly diverse group affects primary production at the basin scale. Here, we combined flow cytometric cell sorting, NaH14CO3 radiotracer incubations and class-specific fluorescence in situ hybridization (FISH) probes to determine cell- and biomass-specific inorganic carbon fixation rates and taxonomic composition of two major photosynthetic picoeukaryote groups on a ?7500-km-long latitudinal transect across the Atlantic Ocean (Atlantic Meridional Transect, AMT19). We show that even though larger cells have, on average, cell-specific CO2 uptake rates ?5 times higher than the smaller ones, the average biomass-specific uptake is statistically similar for both groups. On the other hand, even at a high taxonomic level, i.e. class, the contributions to both groups by Prymnesiophyceae, Chrysophyceae and Pelagophyceae are significantly different (P < 0.001 in all cases). We therefore conclude that these group's carbon fixation rates are independent of the taxonomic composition of photosynthetic picoeukaryotes across the Atlantic Ocean. Because the above applies across different oceanic regions the diversity changes seem to be a secondary factor determining primary production

Control of human behavior, mental processes and consciousness : essays in honor of the 60th birthday of August Flammer
No full textIn this book, an international group of leading scientists present perspectives on the control of human behavior, awareness, consciousness, and the meaning and function of perceived control or self-efficacy in people's lives. The book breaks down the barriers between subdisciplines, and thus constitutes an occasion to reflect on various facets of control in human life. Each expert reviews his or her field through the lens of perceived control and shows how these insights can be applied in practice
Consensus Clustering From Experts' Partitions for Patients' nevi: Model the Ugly Duckling
No full textUgly duckling (UD) concept is widely admitted as major criteria for malignant melanoma (MM) detection. It demonstrates that nevi in the same individual tend to resemble one another and human brain can identify a few similarity clusters, which include all nevi sharing the same morphological features. UD is the nevus that does not fit into any of the clusters of the individual, likely to be suspicious (i.e. MM). Our research program was to modeling the perceived similarity clusters (PSC) as a basis for a computer-aided diagnosis system. In the present part of the study, nine observers (dermatologists) participated to do the clustering of nevi and to identify the UDs using dermoscopic images of nevi of 80 individuals (2089 nevi with 7 histologically confirmed melanomas). Observers identified all confirmed melanomas as UDs (100% sensitivity and 98% specificity). The observers tend to be concordant about the identification of PSCs. We combined the multiple clusterings of experts to find the consensus clustering, which yields a stable and robust final clustering that is in agreement with the multiple clusterings of experts. We demonstrated the limited variability of nevi patterns per individual (2.45 PSCs in average), whatever the number of nevi, which human brain has a natural intuitive ability to perceive
Comparison of phosphate uptake rates by the smallest plastidic and aplastidic protists in the North Atlantic subtropical gyre
No full textThe smallest phototrophic protists (< 3 mu m) are important primary producers in oligotrophic subtropical gyres - the Earth's largest ecosystems. In order to elucidate how these protists meet their inorganic nutrient requirements, we compared the phosphate uptake rates of plastidic and aplastidic protists in the phosphate-depleted subtropical and tropical North Atlantic (4-29 degrees N) using a combination of radiotracers and flow cytometric sorting on two Atlantic Meridional Transect cruises. Plastidic protists were divided into two groups according to their size (< 2 and 2-3 mu m). Both groups of plastidic protists showed higher phosphate uptake rates per cell than the aplastidic protists. Although the phosphate uptake rates of protist cells were on average seven times (P < 0.001) higher than those of bacterioplankton, the biomass-specific phosphate uptake rates of protists were one fourth to one twentieth of an average bacterioplankton cell. The unsustainably low biomass-specific phosphate uptake by both plastidic and aplastidic protists suggests the existence of a common alternative means of phosphorus acquisition - predation on phosphorus-rich bacterioplankton cells
Structural phase transformation observed with in-situ mechanical stress measurement during the growth of amorphous Fe100-xZrx films
No full textFe-100-xZrx thin films (0 < x < 7) grow on top of a Zr base layer in the amorphous phase up to a concentration dependent critical film thickness. At this critical thickness a polymorphous phase transformation of the Fe-100-x-Zrx layer takes place. Zr concentrations higher than 7 at% lead to an amorphous phase for all thicknesses. Here we report on in-situ mechanical stress measurements using an optical deflection technique. Different substrate thicknesses and alloy compositions up to 10 at% Zr were investigated. It is observed that stress builds up only after crystallization. No discontinuity of the deflection is observed during the polymorphous crystallization. The behaviour of stress development is well described by an analytical equation discussed by Cammarata [11]
