Bootstrap Unit Root Tests: Comparison and Extensions [PDF]
In this paper we study and compare the properties of several bootstrap unit root tests recently proposed in the literature. The tests are Dickey-Fuller or Augmented DF-tests, either based on residuals from an autoregression and the use of the block ...

An early nodulin-like protein accumulates in the sieve element plasma membrane of Arabidopsis
, 2007 Membrane proteins within the sieve element-companion cell complex have essential roles in the physiological functioningof the phloem. The monoclonal antibody line RS6, selected from hybridomas raised against sieve elements isolated fromCalifornia shield ...

Reconstruction of the evolutionary history of sieve element architecture in seed plants
The phloem is a vital sugar-transporting tissue in vascular plants, but its evolution remains poorly characterised. The specialised sugar conducting cells of phloem, termed ‘sieve elements’ in gymnosperms and angiosperms, can be characterised ...

A Sieve Bootstrap Test for Cointegration in a Conditional Error Correction Model [PDF]
In this paper we propose a bootstrap version of the Wald test for cointegration in a single-equation conditional error correction model. The multivariate sieve bootstrap is used to deal with dependence in the series. We show that the introduced bootstrap
