No full textWanniyala hakgala Huber & Benjamin, 2005 Wanniyala hakgala Huber & Benjamin, 2005: 3317, figs 5f–i, 7e–h, 8 (♂ ♀, Sri Lanka). Diagnosis (amendments; see Huber & Benjamin 2005). Males are distinguished from congeners by retrolateral sclerite of procursus with large sickle-shaped dorsal process (Huber & Benjamin 2005: figs 7e, f) and by modification of clypeus (pair of small lateral processes, with median indistinct hump). Females are easily distinguished from most known congeners (except W. mudita sp. n., W. orientalis sp. n.) by shape of epigynum (strongly projecting and pointed in lateral view; Huber & Benjamin 2005: fig. 5i); they differ from both species by details of internal genitalia (elongated pore plates; Huber & Benjamin 2005: fig. 7h); from W. mudita also by narrower anterior ‘valve’. New record. SRI LANKA: 1♂ in pure ethanol, ZFMK (Benj 51), Uva Province, Badulla District, Passara-Ella road (B113), Mausagalla [=Maussagolla] (6.909°N, 81.132°E), 22.i.2014 (S.P. Benjamin, N. Athukorala). Description (amendments; see Huber & Benjamin 2005). Procursi of male from Mausagalla appear identical in all aspects to those of the type locality illustrated in Huber & Benjamin (2005, figs 7e, f). Measurements of this specimen: tibia 1: 3.9; distance between tips of cheliceral apophyses: 0.79. Sternum black with light median mark anteriorly; dark rings subdistally on femora and tibiae. Distribution. Known from two localities in central Sri Lanka (Fig. 227). The 4♀ from Kandy (deposited in RMNH) identified in Huber & Benjamin (2005) as W. hakgala are here considered to represent W. mudita (see below). The single female from Kumbukana (ZMUT AA 3632) identified in Huber & Benjamin (2005) as W. hakgala was reexamined and is here considered to represent W. orientalis (see below).Published as part of Huber, Bernhard A., 2019, The pholcid spiders of Sri Lanka (Araneae: Pholcidae), pp. 1-57 in Zootaxa 4550 (1) on pages 33-34, DOI: 10.11646/zootaxa.4550.1.1, http://zenodo.org/record/262503

Progress in the accuracy and resolution of the Late Cretaceous Planktonic Foraminiferal Biozonation: diversification of Dicarinella and Marginotruncana and biostratigraphic implications.
No full textA recurrent feature in the evolutionary history of the planktonic foraminifera is the modification from unkeeled and globigeriniform ancestors to keeled and globorotaliform descendants. Single-keeled trochospiral taxa first appear in the Albian and correspond to a pronounced species diversification associated with an increasing degree of calcification and test size. The acquirement of peripheral double-keels is an evolutionary novelty first observed in the uppermost Cenomanian-lower Turonian assemblages.
Double-keeled specimens are traditionally included in the genus Dicarinella if all the umbilical sutures are radial and depressed, whereas those forms with raised and sigmoidal to curved umbilical sutures have been included in Marginotruncana. After the extinction of the single-keeled rotaliporids close to the Cenomanian/Turonian boundary, the recovery of keeled planktonic foraminifera was relatively slow in the basal Turonian and then progressively accelerated. This diversification is well documented by the appearance of several species of Dicarinella and Marginotruncana that dominate the Turonian-Santonian assemblages.
Superimposed on this evolutionary trend are occurrences of common transitional forms yielding morphological features in between Dicarinella and Marginotruncana (i.e., umbilical sutures initially raised then depressed and/or initially radial then curved, and combined patterns of the sutures), so that some of the diagnostic characters currently used to discriminate genera appear inadequate.
In an effort to determine the ancestor-descendant relationships among species of Dicarinella, Marginotruncana and taxa possessing intermediate morphological features, the well preserved and highly diversified planktonic foraminiferal assemblages recovered at Tanzania Drilling Project (TDP) Sites 31 and 39 (coastal Tanzania; see Jiménez Berrocoso et al., 2012) and at Ocean Drilling Program (ODP) Sites 762 and 763 (Exmouth Plateau; see Petrizzo et al., 2011) have been studied.
The morphological features displayed by the Turonian to Santonian keeled taxa have been analyzed for reconstructing lineages of descendants based on stratophenetic observations.
Results confirm that some of the keeled taxa assigned to Dicarinella and Marginotruncana derive from different ancestral species (i.e., Gonzalez Donoso and Linares in Robaszynski et al., 1990). Moreover, our findings and observations are used to revise the current classification scheme, to derive a more accurate sequence of bioevents that appear to be promising for regional and global correlations, and for refinement of the planktonic foraminiferal biozonation.

Robust Linear and Support Vector Regression
No full textThe robust Huber M-estimator, a differentiable cost function that is quadratic for small errors and linear otherwise, is
modeled exactly, in the original primal space of the problem, by an easily solvable simple convex quadratic program for both linear and
nonlinear support vector estimators. Previous models were significantly more complex or formulated in the dual space and most
involved specialized numerical algorithms for solving the robust Huber linear estimator [3], [6], [12], [13], [14], [23], [28]. Numerical test
comparisons with these algorithms indicate the computational effectiveness of the new quadratic programming model for both linear
and nonlinear support vector problems. Results are shown on problems with as many as 20,000 data points, with considerably faster
running times on larger problems
