RESUMEN
Rational design of improved transition metal based materials mostly relies on their electronic structure descriptors, typically estimated by density functional theory and so unduly affected by self-interaction or static correlation errors. Here we show for all 30 transition metals that original or width-corrected d-band centers, and Hilbert transform highest peak descriptors are unaffected by self-interaction, while poor treatment of static correlation by hybrid functionals leads to an unbalanced description. Thus, descriptors have a general validity unbiased by a specific computational method.
RESUMEN
Quality of life of a patient constitutes integrated index of the treatment efficacy. One of parts of the "quality of life" term is a restriction of vital activities - disability. It is for the first time, when the prognostication system was proposed for the risk estimation of disability occurrence in patients, operated on for complicated gastroduodenal ulcer, which was elaborated on background of the step by step discriminant analysis. Application of prognostication system, in particular, its simplified variant, permits to apply it widely for choosing of optimal operative treatment method, which prophylaxes the risk of disability occurrence.

In 1982-1996 yrs of 8822 patients with ulcer bleeding in 122 (1.4%) it was concurrent with gastroduodenal ulcer perforation. In 34 (27.9%) simultaneous perforation and bleeding were observed, in 88 (72.1%) perforation occurred in 1-7 days after bleeding, in 48 (54.5%) it was concurrent with recurrent bleeding. Postoperative mortality lowered from 25 to 7.1% due to application of the principles elaborated.
