Part 2. The lyrics of The Beatle’ song ‘Michelle’ (1965) is linguistically scrutinized in regards of various aspects. The analysis involves those cultural circumstances under which the song was created, as well as the track place in the group legacy. As the author states the major collision is hidden in the general monolingualism of its characters shown through the foreign-language component, yet employed as a device displaying their communication collapse.

В настоящей работе проводится исследование однозонной двухмерной модели Хаббарда в рамках кластерной теории возмущений. Рассмотрение ограничено приближением ближайших соседей. Первоначальная двумерная квадратная решетка разбивается на кластеры 2x2, образующие квадратную сверхрешетку. Методом точной диагонализации определяется полный набор собственных векторов и собственных значений отдельного кластера. На этом базисе проводится построение Х-операторов, через которые переопределяется гамильтониан задачи. В приближении Хаббард-I вычисляется спектральная функция, позволяющая исследовать распределение спектрального веса квазичастиц в хаббардовских подзонах. Исследовано влияние внутрищелевых состояний на пиннинг химического потенциала при малых концентрациях дырок. In this paper we study the single-band two-dimensional Hubbard model in the framework of the clus- ter perturbation theory. Consideration is limited to nearest-neighbor approximation. The original two- dimensional square lattice is divided into clusters of 2x2, forming a square superlattice. The complete set of eigenvectors and eigenvalues of a single cluster is determined by exact diagonalization method. On this basis, we construct X-operators, through which overrides the Hamiltonian of the problem. The spectral function is computed within the Hubbard-I approximation. This function allows to explore the distribution of spectral weight of the quasiparticles in the Hubbard subbands. The effect of the in-gap states at the pinning of the chemical potential at low concentrations of holes is explored.

A small free-living marine bacteriotrophic flagellate Klosteria bodomorphis gen. and sp. nov. was investigated by electron microscopy and molecular methods. This protist has paraxial rods of typical bodonid structure in the flagella, mastigonemes on the anterior flagellum, two nearly parallel basal bodies and discoid mitochondrial cristae. The flagellar pocket and cytostome/cytopharynx complex are supported by two microtubular roots and reinforced microtubular band (mtr). These features confirm that K. bodomorphis is a bodonid related to Bodo. However, the presence of a layer of dense glycocalyx on the flagella and one battery of cylindrical trichocysts with reticular walls makes it more similar to Rhynchobodo/Phyllomitus, although this flagellate characterized by pankinetoplasty. Phylogenetic analysis using the SSU rRNA gene is congruent with the ultrastructural studies and strongly confirms the close relationship of K. bodomorphis to the genus Rhynchobodo within the order Kinetoplastida.
