, 2000
En l'esparver cendrós, els mascles acostumen a arribar als territoris de cria, procedents d'Àfrica, uns dies abans que les femelles. Són els mascles els que s'estableixen en un territori i sembla que és la femella la que escull el lloc on ubicar el niu ...

Dynamic Bayesian Network for Continuous Health Index Estimation and Condition Assessment of Power Transformers

High Voltage, EarlyView.
ABSTRACT To address the limitations of traditional transformer health index (HI), such as high dependence on data integrity and inability to assist in diagnosing latent faults, this study proposes an HI prediction method based on dynamic Bayesian network (DBN).

The Syntactic Status of Subject Clitics: A Problem from Venetan SE‐Constructions

Transactions of the Philological Society, EarlyView.
Abstract This article reopens the discussion on the syntax of subject clitics (SCLs) in Venetan dialects by providing a problematic piece of data and outlining its theoretical consequences. New evidence from se‐constructions in Alto Polesine Venetan (APV) shows that SCLs resist a unitary categorisation even within the same dialect group: in varieties ...

New Bivariate Copulas via Lomax Distribution Generated Distortions

AppliedMath
We develop a framework for creating distortion functions that are used to construct new bivariate copulas. It is achieved by transforming non-negative random variables with Lomax-related distributions.

Neutral Forms of Be as Default Forms: The Utility of Underspecification and Blocking in a Welsh Morphosyntactic Phenomenon

Transactions of the Philological Society, EarlyView.

These specialised forms of ‘be’ are incompatible with positive main‐clause declarative complementizers, despite their apparent featural compatibility. For most speakers, they are also blocked from if‐clauses; although, I report on data regarding their ...
