Goniagnathus bifurcatus was described from a holotype male and one paratype with original data: Karachi, grass, 10.xi. 1985, Qadeer (ZMUK); no type specimens could be found. Goniagnathus (Tropicognathus) quadripinnatus Dash & Viraktamath (Plate 1, i; Figs. 14, 15). Material examined. Pakistan: 13, 1 Ƥ, Tando Jam, 28.iv.07. Remarks. The specimens from Pakistan match the original figures of this species but the apical aedeagal processes are slightly different in shape in lateral view. Hecalini Remarks. The following references deal with the Oriental species of Hecalini: Morrison (1973), Rao & Ramakrishnan (1990) and Dash & Viraktamath (1997). Members of the tribe can be distinguished externally by the extended and flattened head, particularly in the female, and the laterofrontal sutures terminating medially and distad of the ocelli (Figs 16 a). Also, in the female the second valvulae are humped and lack both teeth and dorsal sclerotised and hyaline areas (Fig. 16 e), the first valvifers have a posterior lobe and the first valvulae have maculose submarginal sculpture both dorsally and apicoventrally (Fig. 16 f).Published as part of Khatri, Imran & Webb, Michael D., 2010, The Deltocephalinae leafhoppers of Pakistan (Hemiptera, Cicadellidae), pp. 1-47 in Zootaxa 2365 on page 11, DOI: 10.5281/zenodo.19365

Statistical approaches for the definition of landslide rainfall thresholds and their uncertainty using rain gauge and satellite data
No full textModels for forecasting rainfall-induced landslides are mostly based on the identification of empirical rainfall thresholds obtained exploiting rain gauge data. Despite their increased availability, satellite rainfall estimates are scarcely used for this purpose. Satellite data should be useful in ungauged and remote areas, or should provide a significant spatial and temporal reference in gauged areas. In this paper, the analysis of the reliability of rainfall thresholds based on rainfall remote sensed and rain gauge data for the prediction of landslide occurrence is carried out. To date, the estimation of the uncertainty associated with the empirical rainfall thresholds is mostly based on a bootstrap resampling of the rainfall duration and the cumulated event rainfall pairs (D,E) characterizing rainfall events responsible for past failures. This estimation does not consider the measurement uncertainty associated with D and E. In the paper, we propose (i) a new automated procedure to reconstruct ED conditions responsible for the landslide triggering and their uncertainties, and (ii) three new methods to identify rainfall threshold for the possible landslide occurrence, exploiting rain gauge and satellite data. In particular, the proposed methods are based on Least Square (LS), Quantile Regression (QR) and Nonlinear Least Square (NLS) statistical approaches. We applied the new procedure and methods to define empirical rainfall thresholds and their associated uncertainties in the Umbria region (central Italy) using both rain-gauge measurements and satellite estimates. We finally validated the thresholds and tested the effectiveness of the different threshold definition methods with independent landslide information. The NLS method among the others performed better in calculating thresholds in the full range of rainfall durations. We found that the thresholds obtained from satellite data are lower than those obtained from rain gauge measurements. This is in agreement with the literature, where satellite rainfall data underestimate the “ground” rainfall registered by rain gauges
Abnormal development of embryos induced by inbreeding in Delphacodes pellucida Fabricius and Delphacodes dubia Kirschbaum (Araeopidae, Homoptera), vectors of European wheat striate mosaic virus
No full textThe embryos of Delphacodes pellucida Fabricius show various types of abnormalities, and the proportion of abnormal eggs depends on the degree of relationship between the parents. Abnormalities were rare in eggs of females mated to males of another family, but they increased with sibling matings. Many eggs from the first generation of inbreeding were abnormal and failed to hatch, and in the second generation some that hatched produced sterile females. Embryos became abnormal at various stages of growth.
D. pellucida is a vector of European wheat striate mosaic virus, and the eggs produced by several groups of infective and noninfective females of laboratory colonies were compared, but no consistent effects of virus on embryonic development were noted.
Delphacodes dubia Kirschbaum, a newly discovered vector of European wheat striate mosaic virus, showed abnormalities of embryonic development similar to D. pellucida. Inbreeding, whether or not the individuals were infective, caused abnormalities
Changes in Extreme Precipitation and Landslides Over High Mountain Asia
No full textHigh Mountain Asia is impacted by extreme monsoonal rainfall that triggers landslides in large proportions relative to global distributions, resulting in substantial human impacts and damage to infrastructure each year. Previous landslide research has qualitatively estimated how patterns in landslide activity may change based on climate change scenarios. We present the first quantitative view of potential modulation in future landslide activity over the High Mountain Asia region leveraging a new landslide hazard model and precipitation data from satellite and Global Climate Model sources. In doing so, we find that the rate of increase in landslide activity at the end of the century is expected to be greatest over areas covered by current glaciers and glacial lakes, potentially exacerbating the impacts of cascading hazards on populations downstream. This work demonstrates the potential of Global Climate Models and satellite-based precipitation estimates to characterize landslide hazards at time scales affected by climate change
MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
