We derive new cut-set bounds on the achievable rates in a general multi-terminal network with finite number of states. Multiple states are common in communication networks in the form of multiple channel and nodes’ states. Our results are broadly applicable and provide much tighter upper bounds than the known single state min-cut max-flow theorem, and hence form an important new tool to bound t...

A pharmacologically active agent was easily extracted by aqueous or organic solvents from laboratory plastic tubes (Falcon Blue Max) and has been chemically identified as bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate. This compound (approximately 12 micrograms per tube approximately 25 nmol) blocked 1,4-dihydropyridine-sensitive 45Ca2+ uptake into GH3 cells with an IC50 value of 3.6 microM, inh...

multicast routing is one of the most important services in multi radio multi channel (mrmc) wireless mesh networks (wmn). multicast routing performance in wmns could be improved by choosing the best routes and the routes that have minimum interference to reach multicast receivers. in this paper we want to address the multicast routing problem for a given channel assignment in wmns. the channels...

many appealing multicast services such as on-demand tv, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. when multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. designing a good multicast tree to route data packets could enhance the...

Discrimination studies suggest that two, and only two, channels encode relative spatial phase shifts in compound gratings (Bennett & Banks, 1991; Field & Nachmias, 1984). The more sensitive channel consists of even-symmetric filters and responds best to cosine phase shifts (e.g., 0 degree-180 degrees); the other consists of odd-symmetric filters and responds best to sine phase shifts (e.g., 90 ...

Discovery of K+ channel modulators is limited by low-throughput capacity of existing K+ channel assays. To enable high-throughput screening for novel pharmacological modulators of K+ channels, we developed an assay based on growth of yeast that functionally expresses mammalian Kir2.1 channels. Screening of 10,000 small molecules from a combinatorial chemical library yielded 42 potential Kir2.1 ...

Low-voltage-activated (T-type) calcium channels are important regulators of the transmission of nociceptive information in the primary afferent pathway and finding ligands that modulate these channels is a key focus of the drug discovery field. Recently, we characterized a set of novel compounds with mixed cannabinoid receptor/T-type channel blocking activity and examined their analgesic effect...

First we consider compound channels which have common messages to all the receivers. The best-well known example is TV broadcast. Notice that compound channels are different from broadcast channels with independent messages to different receivers. Fig. 18.1 illustrates the encoding and decoding operations for the compound channel. Since the message is common, we have only one message w. From w,...

The role of the entrance channel in fusion-fission reactions was studied by the theoretical analysis of the experimental evaporation residue excitation functions for reactions leading to the same compound nucleus. The evaporation residues cross sections for xn-channels were calculated in the frame of the combined dinuclear system concept (DNS) and advanced statistical model (ASM). The revealed ...

Two new sulfate monoesters of hemibastadins-1 and -2 were isolated from the marine sponge Ianthella basta (Pallas) from Guam. A third new compound was tentatively assigned the structure 34-O-sulfatobastadin-9. The 1-O-sulfatohemibastadins-1 and –2 were antagonists of the RyR1-FKBP12 Ca channel under conditions where the known compound bastadin-5 exhibits potent agonism (EC50 2 μM).
