Fast time-reversible synchronization of chaotic systems.

Synchronization of nonlinear systems is a crucial problem in many applications, including system identification, data forecasting, compressive sensing, coupled oscillator topologies, and neuromorphic systems. Despite many efficient synchronization techniques being developed, there are some unresolved issues such as fast and reliable synchronization using short or noisy fragments of available data. In this paper, we use time-reversible integration to obtain a synchronization technique as a generalization of the well-known Pecora-Carroll method.

MRI and PET/CT of multiple primary hepatic angiosarcomas in 25-year-old man: A case report.

This study aims to provide a comprehensive understanding of primary hepatic angiosarcoma, a rare and aggressive malignancy, focusing on its diagnostic challenges and unique imaging characteristics. The objective is to delineate the distinctive features of angiosarcoma through computed tomography and magnetic resonance imaging modalities, contributing to improved diagnostic precision and adding valuable insights to the scientific literature. We present the case of a 25-year-old male with primary hepatic angiosarcoma, emphasizing the challenges in distinguishing it from other vascular tumors.

[The characteristics and problems of professional activity of medical workers in conditions of COVID-19 pandemic].

The article is based on the results of sociological survey of medical workers of the Republic of Bashkortostan in 2021. The approaches to issues of their professional activities are analyzed. It is argued that the COVID-19 pandemic has aggravated a number of systemic problems accumulated in health care system in last years.

Synthesis under Normal Conditions and Morphology and Composition of AlF Nanowires.

AlF has interesting electrophysical properties, due to which the material is promising for applications in supercapacitors, UV coatings with low refractive index, excimer laser mirrors, and photolithography. The formation of AlF-based nano- and micro-wires can bring new functionalities to AlF material. AlF nanowires are used, for example, in functionally modified microprobes for a scanning probe microscope.

[Experience of using rhythmic transcranial magnetic stimulation, extracorporeal shock wave therapy and botulinotherapy in individual motor recovery programs in patients with spastic paresis of the lower limb].

Walking disorder is one of the most frequent consequences of stroke and traumatic brain injury, occurring in 80% of cases. Spastic paresis of the muscles of the lower extremity is the cause formed in 20-40% of patients within a few weeks after brain damage. In this case, a complex of symptoms occurs: motor deficiency (muscle paresis), increased muscle tone (spasticity), biomechanical changes in muscles, joints and surrounding tissues, contractures.
