Institute for Condensed Matter Physics, Natl. Acad. Sci. Ukr. 1 Svientsitskii Str., UA-79011 Lviv, Ukraine (Received June 21, 2001) In the limit of infinite spatial dimensions a thermodynamically consistent theory of the strongly correlated electron systems, which is valid for arbitrary value of the Coulombic interaction (U < ∞), is built. For the Hubbard model the total auxiliary single-site p...

Функціонально-вартісний аналіз&nbsp;–&nbsp;метод&nbsp;системного дослідження функцій об'єкта з метою пошуку балансу між його собівартістю і корисністю. аналіз проводять при розробці та постановці на виробництво нових виробів, підвищенні техніко-економічного рівня продукції. При проєктуванні здійснюється пошук оптимальних технічних рішень, встановлення граничних нормативів витрат виготовлення ро...

The acquisition of the fourth language (L4A) is an underinvestigated field, and this study grammatical gender determiners in sequential quadrilinguals (RUS-UKR-ENG-FRA) CEFR A0 to A2 levels French (n=22) aims at testing hypothesis that all three languages are available as a source transfer (L4). results were found be significant by ANOVAs MANOVA, thus presents evidence support learning cumulati...

The authors performed a matched-paired study comparing 22 computer-assisted surgery (CAS)-unicompartmental knee replacement (UKR) revisions with a similar group of knee replacement revisions performed conventionally. The aim of the study was to assess differences in implants used in the revision, surgical time, limb alignment, joint line restoration, and procedure costs. In the conventional gro...

The asymmetric unit of the second polymorph of the title compound, C(2)H(9)NO(6)P(2), contains one mol-ecule existing as a zwitterion. The N atom of the ammonio group is protonated and one of the phospho-nic acid groups is deprotonated. Bond lengths and angles are similar in both polymorphs. Besides the differences in cell parameters, the most significant structural difference between this stru...

In dextrous hand control, the implementation of manipulation movements still is a complex and intricate undertaking. Often, a lot of object physics and modelling effort has to be incorporated into a controller working only for a very restricted task specification and performing quite artificially looking movements. In this paper, starting from our representation for dextrous grasping, namely th...
