In the structure of the title compound, [PdCl(2)(C(5)H(5)N)(2)], the Pd(II) atom is located on an inversion centre and the pyridine rings are coplanar. There is inter-molecular π-π stacking between the pyridyl rings, with a centroid-to-centroid separation of 3.916 (1) Å. The structure is a new polymorph of two previously determined structures [Viossat, Dung & Robert (1993 ▶). Acta Cryst. C49, 8...

Thin Ti layers (10 nm) are grown on top of a clean Si(ll1) substrate. Heating these layers initiates a solid state reaction, yielding a monosilicide phase at 350 o C and a C49 disilicide at 450 o C. The present study concerns the growth kinetics of both phases by means of ellipsometry. A diffusion-limited growth kinetics is found for the monosilicide formation. However, two growth rates are obs...

The transformation from the C49 to the C54 phase in TiSi2 thin films has been studied for more than a decade because of its importance to the semiconductor industry. In previous work we identified three dominant C54 orientations in TiSi2 thin films on Si(001) substrates using X-ray pole figure analysis. In the current study the evolution of the three prominent C54 texture components was further...

In this paper we propose a subsampling estimator for the distribution of statistics diverging at either known or unknown rates when the underlying time series is strictly stationary and strong mixing. Based on our results we provide a detailed discussion how to estimate extreme order statistics with dependent data and present two applications to assessing nancial market risk. Our method perform...

We present the results of rest-frame ultraviolet spectroscopic observations of a sample of 14 z ∼ 3 star-forming galaxies in the SSA22a field. These spectra are characterized by unprecedented depth in the Lyman-continuum region. For the first time, we have detected escaping ionizing radiation from individual galaxies at high redshift, with two of the 14 objects showing significant emission belo...

We present a new financial decision making model by using the fuzzy generalized probabilistic weighted averaging (FGPWA) operator. The main advantage of this new approach is that it is able to deal with probabilities (objective information) and weighted averages (subjective information) in the same formulation. Moreover, it is also able to deal with an uncertain environment that can be assessed...

In this paper, we use maximum entropy to estimate the parameters in an economic model. We demonstrate the use of the generalized maximum entropy (GME) estimator, describe how to specify the GME parameter support matrix, and examine the sensitivity of GME estimates to the parameter and error bounds. We impose binding inequality restrictions through the GME parameter support matrix and develop a ...

On the domain of Choquet expected utility preferences with risk neutral lottery evaluation and totally monotone capacities, we demonstrate that proper scoring rules do not exist. This implies the non-existence of proper scoring rules for any larger class of preferences (CEU with convex capacities, multiple priors). We also show that if an agent whose behavior conforms to the multiple priors mod...

The title compound, C13H13NO2, was previously described in space group P21/c by He et al. [Acta Cryst. (1993), C49, 2000-2002]. The ethyl group is disordered over two sets of sites in a 0.615 (10):0.385 (10) ratio. The C-O-C-C torsion angles containing the ethyl group are -111.6 (10) and 177.9 (7)°, while in the previously reported polymorph, the torsion angle is -167.3 (2)°. The molecules pack...
