Theoretical and methodological grounds for the modernization of the tax administration system
The article stands for the theoretical underpinning of economic grounds of tax system and its building on the basis of social- and business-oriented socioeconomic features.
Authors proved the need for tax process management that represent the features of government-society-taxpayer relations with taxpayer’s leading role as macroeconomic tool for economic regulation process as well as providing the sustainable and balanced economic growth and innovative modernization of Russian economy.peer-reviewe

Эндометриоз под маской рака мочевого пузыря (обзор литературы и описание трех собственных наблюдений)
The authors consider the prevalence, etiology, pathogenesis, symptoms, diagnosis, differential diagnosis, and surgical treatment of bladder endometriosis on the basis of 3 own cases and an analysis of 384 cases described in world literature. It has been established that endometriosis may mimic bladder carcinoma. The detection of the cyclic pattern of gross hematuria and other symptoms (during menstruation) and that of the characteristic type of tumorous endrometrioid mass at cystoscopy performed during or just prior to menstruation are of key importance for the differential diagnosis of endometriosis and carcinoma. Indications for open resection of the bladder, transurethral resection, and minimally invasive laparoscopic surgery are determined.Рассмотрены распространенность, этиология, патогенез, симптоматика, диагностика, дифференциальная диагностика и оперативное лечение эндометриоза мочевого пузыря на основе 3 собственных наблюдений и анализа 384 случаев, описанных в мировой литературе. Установлено, что эндометриоз нередко может протекать под маской рака мочевого пузыря. В дифференциальной диагностике эндометриоза от рака главное значение имеют выявление циклического характера макрогематурии и других симптомов (сопутствующих менструации), обнаружение характерных признаков опухолевидного эндометриоидного образования при цистоскопии, выполненной во время менструации или непосредственно перед ней. Определены показания к открытой резекции мочевого пузыря, ТУР и мини-инвазивной лапароскопической операции
Ferroelectric nanostructure having switchable multi-stable vortex states
A ferroelectric nanostructure formed as a low dimensional nanoscale ferroelectric material having at least one vortex ring of polarization generating an ordered toroid moment switchable between multi-stable states. A stress-free ferroelectric nanodot under open-circuit-like electrical boundary conditions maintains such a vortex structure for their local dipoles when subject to a transverse inhomogeneous static electric field controlling the direction of the macroscopic toroidal moment. Stress is also capable of controlling the vortex\u27s chirality because of the electromechanical coupling that exists in ferroelectric nanodots
MIGHTEE-HI: The relation between the HI gas in galaxies and the cosmic web
We study the 3D axis of rotation (3D spin) of 77 HI galaxies from the
MIGHTEE-HI Early Science observations, and its relation to the filaments of the
cosmic web. For this HI-selected sample, the alignment between the spin axis
and the closest filament () is higher for galaxies
closer to the filaments, with for galaxies Mpc from their closest filament compared to
for galaxies at Mpc. We find that galaxies with a low HI-to-stellar mass ratio
() are more aligned with their closest
filaments, with ; whilst
galaxies with () tend to be
mis-aligned, with . We
find tentative evidence that the spin axis of HI-selected galaxies tend to be
aligned with associated filaments ( Mpc), but this depends on the gas
fractions. Galaxies that have accumulated more stellar mass compared to their
gas mass tend towards stronger alignment. Our results suggest that those
galaxies that have accrued high gas fraction with respect to their stellar mass
may have had their spin axis alignment with the filament disrupted by a recent
gas-rich merger, whereas the spin vector for those galaxies in which the
neutral gas has not been strongly replenished through a recent merger tend to
orientate towards alignment with the filament. We also investigate the spin
transition between galaxies with a high HI content and a low HI content at a
threshold of found in simulations,
however we find no evidence for such a transition with the current data.Comment: 11 pages, 9 figures, 5 tables, accepted for publication in MNRA
Atomistic simulations of self-trapped exciton formation in silicon nanostructures: The transition from quantum dots to nanowires
Using an approximate time-dependent density functional theory method, we
calculate the absorption and luminescence spectra for hydrogen passivated
silicon nanoscale structures with large aspect ratio. The effect of electron
confinement in axial and radial directions is systematically investigated.
Excited state relaxation leads to significant Stokes shifts for short nanorods
with lengths less than 2 nm, but has little effect on the luminescence
intensity. The formation of self-trapped excitons is likewise observed for
short nanostructures only; longer wires exhibit fully delocalized excitons with
neglible geometrical distortion at the excited state minimum.Comment: 10 pages, 4 figure
