The FM and PL Libraries Documentation
No full textBuilding complex SPMD code in an ecient and portable way is nowadays a challenge, especially when there is no uniformity of tools and libraries across platforms. The Fast Messages (FM) and the Portability Library (PL) where both designed to provide the basis of an abstract enough framework for C, so that problems can be coded and ported to any supported platform with no more than a few changes in the makeles and a recompilation. The FM library provides a message passing communications library built around the Berkeley Active Messages library. The PL library provides the primitives for host to node communication for problem initialization and results collection, as well as other miscellaneous and potentially non-portable primitives. This technical report contains the documentation for both libraries.Technical report LCSR-TR-25
Relicts and radiations: Phylogenomics of an Australasian lizard clade with east Gondwanan origins (Gekkota: Diplodactyloidea)
No full textAustralasia harbors very high squamate diversity and is a center of endemicity for a number of major lineages. However, despite this diversity, the diplodactyloid geckos of Australia, New Caledonia, and New Zealand (comprised of three endemic families and >200 species) are the only extant squamates with unequivocal Mesozoic origins in the region. Diplodactyloid geckos also exhibit notable phenotypic and ecological diversity, most strikingly illustrated by the functionally limbless pygopods. Here, we present the first phylogenomic analyses of the pattern and timing of diplodactyloid evolution, based on a dataset of more than 4000 ultraconserved elements (UCEs) from 180 species. These analyses fully resolve nearly all nodes, including a number of intergeneric relationships that have proven problematic in previous studies. The hypothesis that New Caledonia and New Zealand clades represent independent post-KT boundary colonization events of Tasmantis from Australian ancestors is confirmed. Phylogenetic relationships recovered here further highlight contrasting patterns of diversity, most strikingly between insular and/or morphologically highly derived clades that have diversified rapidly, as opposed to other species poor and phylogenetically divergent relictual lineages on mainland Australia. Our new timetree suggests slightly older branching times than previous analyses and does not find a mass extinction event in the early Cenozoic. Finally, our new phylogeny highlights caudal variation across the clade. Most strikingly, the distinctive leaf-tail morphology shown by one family may in fact be plesiomorphic.No Full Tex

Introduction to Urban Science: Evidence and Theory of Cities as Complex Systems
No full textLuís Bettencourt provides a timely, comprehensive, and rigorous treatment of urban space, by contributing to the
advancement of knowledge in the field of urban science. The author develops a valuable scientific guide for researchers,
policymakers, practitioners, and students interested in understanding cities as complex systems. Today, more than half of
world's population lives in urban areas, and, according to theWorld Bank data, by 2045, urban citizens will increase up to
6 billion. Cities of different sizes will play a pivotal role in the postpandemic recovery and, most importantly, they will
make the green transition of our economies and societies really work in coming years. Therefore, understanding “how
each city and every one of its people is the result of the aggregation of many choices, accidents, and influences from
their compounded joint history” (p. xxi) becomes crucial to manage present and future local and global challenges
MultiEmo: Multilingual, Multilevel, Multidomain Sentiment Analysis Corpus of Consumer Reviews
No full textMultiEmo, a new benchmark data set for the multilingual sentiment analysis task including 11 languages. The collection contains consumer reviews from four domains: medicine, hotels, products and university. The original reviews in Polish contained 8,216 documents consisting of 57,466 sentences. The reviews were manually annotated with sentiment at the level of the whole document and at the level of a sentence (3 annotators per element). We achieved a high Positive Specific Agreement value of 0.91 for texts and 0.88 for sentences. The collection was then translated automatically into English, Chinese, Italian, Japanese, Russian, German, Spanish, French, Dutch and Portuguese.

The chain-level intersection product for PL pseudomanifolds revisited
No full textAbstract We generalize the PL intersection product for chains on PL manifolds and for intersection chains on PL stratified pseudomanifolds to products of locally finite chains on non-compact spaces that are natural with respect to restriction to open sets. This is necessary to sheafify the intersection product, an essential step in proving duality between the Goresky-MacPherson intersection homology product and the intersection cohomology cup product pairing recently defined by the author and McClure. We also provide a correction to the Goresky-MacPherson proof of a version of Poincaré duality on pseudomanifolds that is used in the construction of the intersection product

Laplacian PL Image Evaluation Implying Correction of Photon Scattering in the Luminescence Detector
No full textAbstractPhotoluminescence (PL) imaging is an established characterization method for investigating local inhomogeneities in solar cells. Conventional evaluation methods are based on the model of independent diodes, leading to wrong results of the local saturation current density J01. The Laplacian-based PL evaluation method does not rely on this model and has the potential to image J01 correctly. First attempts for using this method to evaluate PL images failed. In this contribution it is shown that the main reason for this failure was due to the light scattering effect occurring in the luminescence detector. Implying an image deconvolution procedure to the PL images with the correct point spread function, the result of the Laplacian-based evaluation method nearly shows the correct J01 distribution. It will be shown that the Laplacian-based method has also the potential to image the different dark current contributions (J01, J02 and ohmic) separately, as DLIT can do it already now
