Hidden Higgs Particle
A modification of the standard model of electroweak interactions with the
nonlocal Higgs sector is proposed. Proper form of nonlocality makes Higgs
particles unobservable after the electroweak symmetry breaking. They appear
only as a virtual state because their propagator is an entire function. We
discuss some specific consequences of this approach comparing it with the
conventional standard model.Comment: 15 pages, LaTeX, no figure
Ideas of I. M. Sechenov in aviation and space medicine
The contributions I. M. Sechenov (19th century) made to modern physiology are described, including his studies on gases in the blood (O2 and CO2), and how these studies were the basic building blocks of current efforts in aviation and space medicine. Sechenov also studied hypokinesia, which is becoming important in long duration space flights
