Knowledge of future mortality levels and trends is important for actuarial practice but poses a challenge to actuaries and demographers. The Lee-Carter method, currently used for mortality forecasting, is based on the assumption that the historical evolution of mortality at all age groups is driven by one factor only. This approach cannot capture an additive manner of mortality decline observed...

This brief article describes our contribution to the EVALITA 2009 Parsing Task, dependency track. The TUT and ISST treebanks are augmented with additional features. MIRA is used to find a weight matrix suited for the Covington algorithm, which is subsequently skewed by discriminatively learned hard constraints on dependency lengths. Our skewed algorithm is linear time and thus asymptotically fa...

The finance literature provides substantial evidence on the dependence between international bond markets across developed and emerging countries. Early works in this area were based linear models multivariate GARCH models. However, limitations of these paper re-examines non-linearity, tail structure government US, UK, Japan, Germany, Canada, France, Italy, Australia Eurozone, from January 1970...

The effects of four vine treatments, comprising the application of eugenol and guaiacol (individually or as a mixture) or whiskey lactones on the concentration of glycosidically bound aroma precursors, determined as glycosyl glucose content by HPLC-IR, in Monastrell grapes and their wines were studied. The impact of treatments on the free varietal wine aroma determined by SBSE-GC-MS and descrip...

Anredera cordifolia (Ten.) Steenis, or the synonymous name of Boussingaultia baselloides or Boussingaultia gracilis var. pseudobaselloides, is a South American species of ornamental succulent vine, commonly known as the madeira-vine. The fresh leaves of madeira-vine are frequently used as vegetables. A. cordifolia is an evergreen climber that grows from fleshy rhizomes. The rhizome contained on...

Twenty eight F1 hybrids developed during summer, 2010 by crossing 8 diverse parents in all possible combinations without reciprocals were evaluated for diallel analysis for genetic parameters and graphic representation for yield and yield attributing traits during summer 2011 at College of Horticulture, Rajendranagar, Hyderabad, India. The validity of the assumptions of diallel analysis was con...

Multivariate copulas are commonly used in risk management of financial assets. They allow for very flexible dependency structures, even though they are applied to transformed financial data after marginal time dependencies are removed. This is necessary to facilitate statistical parameter estimation. In this paper we consider a very flexible class of mixed C-vines, which can capture a driving f...
