Objective. To investigate the possibility of using a bioengineering system, which includes an electroencephalograph and a personal computer with a software for synchronous data transmission, recognition and classification of EEG signals, development of directions for intended actions in real time in the combination with the hand exoskeleton (the(More)
We search for the decay B ? ! ? in a sample of over 2 million charged B decays using the CLEO detector. We use the channel in which the tau decays leptonically, and combine this lepton with the missing energy and momentum in the event to form a B candidate. A t to the mass and energy distribution of these B candidates yields ?14 46 signal events. This value(More)
We have used the CLEO-II detector at the Cornell Electron Storage Ring to study the inclusive production of charmonium mesons in a sample of 2.15 million BB events. We nd inclusive branching fractions of (1.130.040.06)% for B!J==X, (0.340.040.03)% for B! 0 X, and (0.400.060.04)% for B! c1 X. We also nd some evidence for the inclusive production of c2. An(More)
CLEO has studied B decays to the nal states``, ``, and !``, wherè = e or. We fully reconstruct these modes using a measurement of the missing energy and momentum in each event to infer the neutrino momentum. With the B 0 and B + modes combined according to isospin predictions for the relative partial widths, we obtain B 0:5)10 ?4 , where the errors are(More)
We have used the CLEO II detector to study the multiplicity of charged particles in the decays of B mesons produced at the Υ(4S) resonance. Using a sample of 1.5×10 6 B meson pairs, we find the mean inclusive charged particle multiplicity to be 10.71 ± 0.02 +0.21 −0.15 for the decay of the pair. This corresponds to a mean multiplicity of 5.36±0.01 +0.11(More)
Objective. To study the potential for use of a bioengineered system consisting of an electroencephalograph, a personal computer running a program for the synchronous data transmission, recognition, and classification of electroencephalogram (EEG) signals, and formation of control commands in real time, combined with a hand exoskeleton (a bioengineered(More)
OBJECTIVE Vision impairment is one of the most typical characteristics of multiple sclerosis (MS). This pathology develops due to the lesions of optic nerves and optic tracts in the brain or eye movement dysfunction. Low contrast vision impairment is very frequent and early detected. We assessed low contrast non-color vision in patients with MS. MATERIAL(More)
immunomodulatory treatment of multiple sclerosis (MS) is directed to the treatment of exacerba-tions and their prophylaxis and to increase the durations of periods of remission. This is approached by giving drugs which modify the course of MS (disease-modifying drugs, DMD), which are divided into first-generation agents (inter-ferons beta-1b and beta-1a,(More)
