Similarity solutions play an important role in many fields of science. The recent book of Barenblatt [2] discusses many examples. Often, outstanding unresolved issues are whether a similarity solution is dynamically attractive, and if it is, to what particular solution does the system evolve. By recasting the dynamic problem in a form to which centre(More)
On the basis of simultaneous measurement of the rheosubcorticogram, polarogram, intracerebral pressure (ICP), ECoG and subcorticogram in patients with electrodes and sensors implanted in the brain, it was established that with the development of the seizure a rapidly reversible growth in the amplitude of deep rheoencephalogram, pO2 and ICP occurs beginning(More)
A lubrication model describes the dynamics of a thin layer of fluid spreading over a solid substrate. But to make forecasts we need to supply correct initial conditions to the model. Remarkably, the initial fluid thickness is not the correct initial thickness for the lubrication model. Theory recently developed in [12, 14] provides the correct projection of(More)
The nonlinear dynamic behavior of microscopic bubbles near a rigid wall is investigated. Oscillations are driven by the ultrasonic pressure field that arises in various biomedical applications such as ultrasound imaging or targeted drug delivery. It is known that, when bubbles approach a blood-vessel wall, their linear dynamic response is modified. This(More)
We report on experimentally observed addition, subtraction, and cancellation of orbital angular momentum (OAM) in the process of parametric four-wave mixing that results in frequency up- and down-converted emission in Rb vapor. Specific features of OAM transfer from resonant laser fields with different optical topological charges to the spatially and(More)
Appraisal of the results of surgical treatment of 7 patients with arterial aneurysms of the carotid channel convinced the authors of the useful applicability of extra-intracranial anastomosis in occlusion of the cerebral arteries. The anastomosis provides for adequate compensation of circulation in the brain in occlusion of not only the internal carotid(More)
The objective of the present study was the comparative analysis of the deaths among the elderly and senile subjects taking into consideration the growing costs of forensic medical expertise at the Nizhni Novgorod Regional Bureau of Forensic Medical Expertise.
