МОДЕЛИРОВАНИЕ ЦИКЛОВ В ЭКОНОМЕТРИЧЕСКИХ МОДЕЛЯХ

The paper describes the author’s algorithm for finding the cyclical components.All time series consist of 4 components,namely trend, seasonal, cyclic and residual component. In the domestic literaturedescribes only to find the trend, seasonal and residual components. And findingcyclic components is similar to findingseasonal. The author believes that the algorithm for finding the seasonal andcyclical cannot be the same.В работе описывается авторский алгоритм нахождения циклической компоненты. Как известно все временные ряды состоят из 4-х составляющих, а именно тренда, сезонной, циклической и остаточной компонент. В отечественной литературе описывается нахождениетолькотренда, сезоннойи остаточной компонент. А нахождение циклической компоненты считается подобным нахождению сезонной. Авторы считают, что алгоритм нахождения сезонной и циклической не может совпадать

Flux Phase as a Dynamic Jahn-Teller Phase: Berryonic Matter in the Cuprates?

There is considerable evidence for some form of charge ordering on the hole-doped stripes in the cuprates, mainly associated with the low-temperature tetragonal phase, but with some evidence for either charge density waves or a flux phase, which is a form of dynamic charge-density wave. These three states form a pseudospin triplet, demonstrating a close connection with the E X e dynamic Jahn-Teller effect, suggesting that the cuprates constitute a form of Berryonic matter. This in turn suggests a new model for the dynamic Jahn-Teller effect as a form of flux phase. A simple model of the Cu-O bond stretching phonons allows an estimate of electron-phonon coupling for these modes, explaining why the half breathing mode softens so much more than the full oxygen breathing mode. The anomalous properties of $O^{2-}$ provide a coupling (correlated hopping) which acts to stabilize density wave phases.Comment: Major Revisions: includes comparisons with specific cuprate phonon modes, 16 eps figures, revte

Optical evidence of Cr3+ ion pairs in (NH4)3[Cr(OH)6Mo6O18]·nH2O

RadiochThe luminescent properties of (NH4)3[Cr(OH)6Mo6O18]·nH2O were investigated for the first time. It was determined that two centers, single Cr3+ ion and Cr3+ ion pair, are responsible for the luminescence properties of this compound. By conducting time-resolved and temperature-dependent emission spectra, energy transfer between the two centers was observed and analyzed. A transfer rate kC equal to 4.6×104 s−1 was determined

Plutonium(IV) precipitates formed in alkaline media in the presence of various anions

The tendency of Pu(IV) to hydrolyze and form true solutions, colloid solutions, or insoluble precipitates has been known since the Manhattan Project. Since then, specific studies have been performed to examine in detail the equilibria of Pu(IV) hydrolytic reactions in various media. Great attention also has been paid to the preparation, structure, and properties of Pu(IV) polymers or colloids. These compounds found an important application in sol-gel technology for the preparation of nuclear fuel materials. A most important result of these works was the conclusion that Pu(IV) hydroxide, after some aging, consists of very small PuO{sub 2} crystallites and should therefore be considered to be Pu(IV) hydrous oxide. However, studies of the properties and behavior of solid Pu(IV) hydroxide in complex heterogeneous systems are rare. The primary goal of this investigation was to obtain data on the composition and properties of Pu(IV) hydrous oxide or other compounds formed in alkaline media under different conditions. Such information is important to understand Pu(IV) behavior and the forms of its existence in the Hanford Site alkaline tank waste sludge. This knowledge then may be applied in assessing plutonium criticality hazards in the storage, retrieval, and treatment of Hanford Site tank wastes as well as in understanding its contribution to the transuranic waste inventory (threshold at 100 nCi/g or about 5 {times} 10{sup {minus}6} M) of the separate solution and solid phases
