[1] In our efforts to bridge the gap between small-scale kinetic modeling and global simulations, we introduced an approach that allows to quantify the interaction between large-scale global magnetospheric dynamics and microphysical processes in diffusion regions near reconnection sites. We use the global MHD code BATS-R-US and replace an ad hoc anomalous(More)
[1] During prolonged intervals of negative interplanetary magnetic field (IMF) Bz the magnetosphere often enters a state in which quasi-periodic, large-amplitude oscillations of energetic particle fluxes are observed at the geosynchronous orbit. We use the global magnetosphere MHD code BATS-R-US output during a long period of steady southward IMF Bz to(More)
Light and scanning electron microscopy was used to study the morphological parameters and ultrastructure of Helix lucorum statocysts and statoliths in Pomatias rivulare statocysts after 56, 93 and 110-day exposure to microgravity aboard the ISS. Increased gravity was simulated by 30-d centrifugation at 6 g. On the first day of recovery, many statoconia and(More)
Postnatal neurogenesis and regeneration opportunities of experimentally damaged areas of the cerebral cortex in various mammalian species were studied by the use of light and electron microscopy, autoradiography and transplantation. Back in the 70s of the 20th century by I. Mepisashvili and her school, it has been found that at the early stages of postnatal(More)
[1] Introducing kinetic corrections into the to BATSRUS code in the magnetotail region leads to fast reconnection rates observed in kinetic simulations and quasi-periodic loading-unloading cycles in the magnetotail during a long period of steady southward interplanetary magnetic field (IMF) Bz (Kuznetsova et al., 2006, 2007). We use the global MHD code(More)
Statocyst epithelial lining of terrestrial pulmonary snail Helix lucorum is a spatially arranged structure consisting of 13 cell ensembles. Each ensemble has a sensory cell surrounded by companion cells. The sensory cell on the anterior statocyst pole is star-shaped due to multiple protoplasmatic protrusions on its body. The remaining 12 polygon-shaped(More)
Statocysts H. Lucorum appear to be the paired formations having a spherical form and locating on dorsolateral surface of pedal ganglia of subesophageal ganglionic complex. Using the method of reconstruction, as well as the method of scanning electron microscopy on paraffin and semithin slices it has been revealed that the epithelial lining of H. Lucorum(More)
[1] The combination of the Wang-Sheeley-Arge (WSA) coronal model, ENLIL heliospherical model version 2.7, and CONED Model version 1.3 (WSA-ENLIL with CONED Model) was employed to form ensemble forecasts for 15 halo coronal mass ejections (halo CMEs). The input parameter distributions were formed from 100 sets of CME cone parameters derived from the CONED(More)
70 The statocyst of mollusks is analogous to the labyrinth of vertebrates. It is involved in righting and compensatory reflexes and spatial orientation [8, 9, 13, 14]. Note that these reactions are possible because the statocyst, like any other organ of balance, contains some inertial mass (solid inclusions of endogenous or exogenous origin). In gastropods,(More)
Vast majority of statoconia in statocysts of Helix lucorum are of oval shape and have smooth surface. Each statoconium in its central part has a nucleus, a spherical mass of 1.5 μ in diameter, surrounded by concentric structures. Minority of statoconia are of subcircular, elongated, rectangular, triangular, irregular, and sometimes fanciful shape and are(More)
