MATERIAL EXAMINED. — JAC3.119.4, JAC3’.22.4, JAC3’.22.15, JAC3’.22.19 and JAC3’.22.44. MEASUREMENTS. — See Table 26. DESCRIPTION Moderately involute to semievolute, whorl section compressed subrectangular with a steep to vertical umbilical wall, a rounded umbilical edge, barely convex flanks, and tabulate but nonbisulcate venter with a high keel. The ribs, which arise near the umbilical edge, are mainly simple, strong, and spaced on the inner and middle whorls, but fade on the outer whorls to become almost smooth in some specimens. The ribs are scarcely flexed on the whorl sides, but ventrally strongly project forward. The specimens available are incomplete but two preserve a half whorl of the BC; all are laterally flattened. The septal suture is not well preserved in the Subbetic specimens. REMARKS According to Morton (1972), the species most closely related to D. hebridica are D. pinguis, and D. hannoverana, but the former is larger and slightly more involute. Also all specimens of D. hebridica show a decline of the ribbing on the BC, whereas this is sporadic in D. pinguis and in no case occurs in D. hannoverana. Morton (1972: 517) proposed a dimorphic relationship between D. hannoverana [M] and D. hebridica [M] on one hand and D. pinguis [m] on the other, assuming that the macroconchs D. hannoverana and D. hebridica are less variable than the microconch, including the microconchs in D. pinguis. The assumption here is that this is correct and consequently the three species are synonymous with each other. In this case, D. pinguis would be the valid species, but the material analysed here, not very abundant and quite deformed, does not provide conclusive results and therefore, it has been deemed preferable to use the three taxonomic names. DISTRIBUTION According to Morton (1972: 517), the HT of D. hebridica comes from the lower part of the Humphriesianum Zone, basal bed of the Upper Sandstones, east of Torvaig, near Portree, Isle of Skye, Scotland. Later, Morton (1975, 1976) introduced a Hebridica Subzone for the upper part of the Sauzei (Propinquans) Zone. The species occurs in this stratigraphic interval in several localities of Western Europe and Morocco. The Subbetic specimens are from the uppermost part of the Propinquans Zone, Hebridica Subzone, of Sierra Alta Coloma (sections JAC 3, JAC3’; Jaén Province).Published as part of Sandoval, José, 2022, Sonniniidae Ammonitina, Middle Jurassic from Southern Spain: taxonomic, biostratigraphical and palaeobiogeographical analysis, pp. 801-851 in Geodiversitas 44 (27) on page 842, DOI: 10.5252/geodiversitas2022v44a27, http://zenodo.org/record/715032
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

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
Determining solubility for finitely generated groups of PL homeomorphisms
No full textFunding: The first and second authors were partially supported by EPSRC grant EP/H011978/1. The third author was partially supported by grants from the Simons Foundation (#245625) and the National Science Foundation (DMS-1313559)The set of finitely generated subgroups of the group PL+(I) of orientation-preserving piecewise-linear homeomorphisms of the unitinterval includes many important groups, most notably R. Thompson’s group F. Here, we show that every finitely generated subgroup G < PL+(I) is either soluble, or contains an embedded copy of the finitely generated, non-soluble Brin-Navas group B, affirming a conjecture of the first author from 2009. In the case that G is soluble, we show the derived length of G is bounded above by the number of breakpoints of any finite set of generators. We specify a set of ‘computable’ subgroups of PL+(I) (which includes R. Thompson’s group F) and give an algorithm which determines whether or not a given finite subset X of such a computable group generates a soluble group. When the group is soluble, the algorithm also determines the derived length of ⟨X⟩. Finally,we give a solution of the membership problem for a particular familyof finitely generated soluble subgroups of any computable subgroup of PL+(I).Peer reviewe
