In this work, a methodology of statistical channel modeling for 60 GHz WLAN systems is proposed and a channel model for the office conference room environment is developed. The proposed methodology takes into account the most important properties of the indoor 60 GHz propagation channel such as large propagation loss and necessity to use steerable(More)
A total of 88 seawater samples were collected during two Russian research expeditions (April-May 2011 and August-September 2012) to the Sea of Japan, the Oyashio Current region near Kuril Islands and the Kuroshio-Oyashio transition area in the western North Pacific Ocean. The observations were made aboard the R/V Pavel Gordienko and Akademik Shokalsky in(More)
This paper presents a detailed analysis of the impact of power amplifier (PA) non-linearity on the performance of single carrier (SC) and OFDM systems in 60 GHz spectrum. The efficiency of the considered systems was analyzed by estimating values of the power amplifier output backoff needed to meet the requirements on the transmit spectrum mask (TSM)(More)
Presented in the article is a clinical case report regarding successfully used hybrid technology in combined lesions of the coronary arteries and the first segment of the left subclavian artery. The patient was subjected to simultaneous hybrid operation, i. e., transaortic angioplasty with stenting of the left subclavian artery by means of the Assurant(More)
Multiunit activity was recorded from strio-pallido-thalamic sites in parkinsonian patients bearing gold electrodes for diagnosis and therapy. The patients voluntarily participated in tasks designed to study neuronal correlates of both physical and semantic characteristics of stimuli as well as motor responses. Six modifications of the stimulus-response(More)
