The Joint European Torus (JET) gamma-ray camera has been recently upgraded with the installation of new detectors, based on LaBr3(Ce) scintillation crystals, which add spectroscopic capability to existing system allowing measurements good energy resolution (5% at 0.622 MeV), a dynamic range from hundreds keV up about 30 MeV, and high counting rate capabilities MCps. First during C38 campaign JE...

In this paper, we propose a multivariate quantile regression method which enables localized analysis on conditional quantiles and global comovement analysis on conditional ranges for high-dimensional data. The proposed method, hereafter referred to as FActorisable Sparse Tail Event Curves, or FASTEC for short, exploits the potential factor structure of multivariate conditional quantiles through...

I extend the theory on factor models by incorporating “local” factors into the model. Local factors affect a decreasing fraction of the observed variables. This implies a continuum of eigenvalues of the covariance matrix, as is commonly observed in applications. I derive conditions under which local factors will be estimated consistently using the common principal component estimator. I further...

Decomposing volatilities into a common market-driven component and an idiosyncratic itemspecific one is an important issue in financial econometrics. This, however, requires the statistical analysis of large panels of time series, hence faces the usual challenges associated with highdimensional data. Factor model methods in such a context are an ideal tool, but they do not readily apply to the ...

Gambierol is a polycyclic ether toxin, which has been isolated from the marine dinoflagellate Gambierdiscus toxicus. A series of gambierol analogues have been prepared from an advanced intermediate of our total synthesis of gambierol and investigated for their toxicity against mice, thus providing the first systematic structure-activity relationships (SAR) of this polycyclic ether class of mari...
