For example, the cohomology ring of a path-connected H-space with finitely generated and free cohomology groups is a Hopf algebra. Also, one can define the Pontryagin product on the homology groups of an H-space. The fundamental group of an H-space is abelian. To see this, let X be an H-space with identity e and let f and g be loops at e.
WECC Intertie Paths. A line on Path 65, part of the Pacific DC Intertie. The Western Electricity Coordinating Council (WECC) coordinates a number of high voltage power links in western North America. [1] [2] [3] These links, known as WECC Intertie Paths, are not necessarily single transmission line, rather they are interties between various areas.
High-throughput satellite ( HTS) is a communications satellite that provides more throughput than a classic FSS satellite (at least twice, though usually by a factor of 20 or more [1]) for the same amount of allocated orbital spectrum, thus significantly reducing cost-per-bit. [2] ViaSat-1 and EchoStar XVII (also known as Jupiter-1 [3]) do ...
Free-space path loss. In telecommunication, the free-space path loss ( FSPL) (also known as free-space loss, FSL) is the attenuation of radio energy between the feedpoints of two antennas that results from the combination of the receiving antenna's capture area plus the obstacle-free, line-of-sight (LoS) path through free space (usually air).

The 5-HT 1A receptor is the most widespread of all the 5-HT receptors. In the central nervous system, 5-HT 1A receptors exist in the cerebral cortex, hippocampus, septum, amygdala, and raphe nucleus in high densities, while low amounts also exist in the basal ganglia and thalamus. [7] [8] [9] The 5-HT 1A receptors in the raphe nucleus are ...
Instrument landing system glide path. In aviation, instrument landing system glide path, commonly referred to as a glide path ( G/P) or glide slope ( G/S ), is "a system of vertical guidance embodied in the instrument landing system which indicates the vertical deviation of the aircraft from its optimum path of descent". [1]
Definitions. A Hamiltonian path or traceable path is a path that visits each vertex of the graph exactly once. A graph that contains a Hamiltonian path is called a traceable graph. A graph is Hamiltonian-connected if for every pair of vertices there is a Hamiltonian path between the two vertices. A Hamiltonian cycle, Hamiltonian circuit, vertex ...
