Upper estimates of transition densities for stable-dominated semigroups [PDF]

open access: yes, 2012
We derive upper estimates of transition densities for Feller semigroups with jump intensities lighter than that of the rotation invariant stable Levy processComment: arXiv admin note: text overlap with arXiv:0903 ...

A new polymorphic material? Structural degeneracy of ZrMn_2

open access: yes, 2004
Based on density functional calculations, we propose that ZrMn_2 is a polymorphic material. We predict that at low temperatures the cubic C15, and the hexagonal C14 and C36 structures of the Laves phase compound ZrMn_2 are nearly equally stable within 0 ...

Deformation of C15 Laves Phase Alloys [PDF]

open access: yesMRS Proceedings, 1994
AbstractDetails of the structure and previous work on the deformation of C15 Laves phases are reviewed. The phase diagram of the Hf-V-Nb system, some metallurgical and physical properties, mechanical behavior, and the deformation mechanisms of HfV2+Nb (C15 HfV2+Nb and V-rich bcc solution) are presented based on our previous work. Theoretical approaches

The Use of Indicator Kriging for Analyzing Prices in the Real Estate Market

open access: yesReal Estate Management and Valuation, 2016
The patterns and relations between real estate prices and the factors which shape them can be presented, among others, in the form of traditional statistical models, as well as by means of geostatistical methods.

A temperature-dependent phase transformation of (E)-2-[(4-chloro-phen-yl)imino]-ace-naphthylen-1-one. [PDF]

open access: yes, 2017
The crystal structure determination based on 90 K data of the title imine ligand, C18H10ClNO, revealed non-merohedral twinning with three twin domains. In our experience, this is an indication of an ordering phase transition.

4-Nitro­phenyl 2-chloro­benzoate [PDF]

open access: yes, 2012
The aromatic rings in the title compound, C13H8ClNO4, enclose a dihedral angle of 39.53 (3)°. The nitro group is almost coplanar with the ring to which it is attached [dihedral angle = 4.31 (1)°].
