Routing in triple loop circulants: A case of networks-on-chip.

In this paper we propose and analyze various approaches to organizing routing in a triple loop circulant topologies as applied to networks-on-chip: static routing based on universal graph search algorithms, such as Dijkstra's algorithm and a possible implementation using Table routing; algorithms created analytically based on an engineering approach with taking into account the structural features of triple loop circulant graphs (Advanced clockwise, Direction selection); an algorithm created on the basis of a mathematical analysis of graph structure and solving the problem of enumerating coefficients at generators (Coefficients finding algorithm). Efficiency, maximum graph paths, occupied memory resources, and calculation time of the algorithms developed are estimated. Comparison of various variants of the algorithms is made and recommendations on their application for the development of networks-on-chip with triple loop circulant topologies are given.

[The diagnosis of subarachnoid hemorrhages in patients with closed craniocerebral trauma].

A scheme of the diagnosis of subarachnoidal hemorrhages in patients with closed craniocerebral injury is offered. It provides for distribution of hemorrhages according to the cause, intensity and stages. The results were investigated in 595 patients.

[The seasonal characteristics of the circadian rhythm of hypoxic resistance and convulsive resistance].

Hypoxic and convulsive resistances have daily rhythms, the pattern of which depends on the year season. Latent period of occurrence of epileptic seizures and time of life at the "height" of 11,000 m above the sea level undergo similar changes in autumn and spring. In winter minimal similarity between daily dynamics of each of these resistances and analogous ones in other seasons is observed, but rhythms of tolerance to hypoxia are maximally synchronized with the rhythms of convulsive resistance.

[The classification of subarachnoid hemorrhages in patients with closed craniocerebral trauma].

The author proposes a working clinical classification of subarachnoidal hemorrhage with closed head injuries according to which hemorrhages are subdivided by their causes, intensity and stage of the disease. Use of this classification in practical medicine will increase exactness of diagnosis and improve treatment results.

[Substantiation of puncture perfusion of the subarachnoid space in experiments with biomanikins].

Experiments were performed in 30 biomannequins. Single puncture subarachnoidal perfusion cleared the subarachnoidal spaces of the brain and medulla free of preinjected dye. The clearance was more radical at the base, in the brain hemisphere cysterns and sulci, at the pons, medullar and spinal levels.

[Use of puncture perfusion in the treatment of patients with brain contusions complicated by subarachnoid hemorrhage].

Puncture-perfusion technique has been introduced for subarachnoidal sanative treatment in patients with brain contusions complicated with subarachnoidal hemorrhages. The intervention resulted in faster reversal of general cerebral and meningeal signs, restoring to normal values the body temperature, heart rate, venous and CSF pressures. Indications and counterindications for this technique application are given.

[Pathogenesis of subarachnoid hemorrhage in closed craniocerebral injuries].

The article deals with the pathogenesis of subarachnoidal haemorrhage related to closed craniocerebral trauma with the reversible deformation of the cranial bones in the phase of damage. It is suggested that the damage to the blood vascular wall and the development of primary subarachnoidal haemorrhage is to a considerable extent caused by the effect of the membrane pump arising after a reversible deformation of cranial bones and manifesting by sharp changes in hydraulic pressure and the movement of liquid media in the subarachnoidal space of the cranial cavity.
