    Description: To initiate studies on how protein-protein interaction (or "interactome") networks relate to multicellular functions, we have mapped a large fraction of the Caenorhabditis elegans interactome network. Starting with a subset of metazoan-specific proteins, more than 4000 interactions were identified from high-throughput, yeast two-hybrid (HT=Y2H) screens. Independent coaffinity purification assays experimentally validated the overall quality of this Y2H data set. Together with already described Y2H interactions and interologs predicted in silico, the current version of the Worm Interactome (WI5) map contains approximately 5500 interactions. Topological and biological features of this interactome network, as well as its integration with phenome and transcriptome data sets, lead to numerous biological hypotheses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1698949/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1698949/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Siming -- Armstrong, Christopher M -- Bertin, Nicolas -- Ge, Hui -- Milstein, Stuart -- Boxem, Mike -- Vidalain, Pierre-Olivier -- Han, Jing-Dong J -- Chesneau, Alban -- Hao, Tong -- Goldberg, Debra S -- Li, Ning -- Martinez, Monica -- Rual, Jean-Francois -- Lamesch, Philippe -- Xu, Lai -- Tewari, Muneesh -- Wong, Sharyl L -- Zhang, Lan V -- Berriz, Gabriel F -- Jacotot, Laurent -- Vaglio, Philippe -- Reboul, Jerome -- Hirozane-Kishikawa, Tomoko -- Li, Qianru -- Gabel, Harrison W -- Elewa, Ahmed -- Baumgartner, Bridget -- Rose, Debra J -- Yu, Haiyuan -- Bosak, Stephanie -- Sequerra, Reynaldo -- Fraser, Andrew -- Mango, Susan E -- Saxton, William M -- Strome, Susan -- Van Den Heuvel, Sander -- Piano, Fabio -- Vandenhaute, Jean -- Sardet, Claude -- Gerstein, Mark -- Doucette-Stamm, Lynn -- Gunsalus, Kristin C -- Harper, J Wade -- Cusick, Michael E -- Roth, Frederick P -- Hill, David E -- Vidal, Marc -- R01 AG011085/AG/NIA NIH HHS/ -- R01 GM034059/GM/NIGMS NIH HHS/ -- R01 GM034059-18/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Jan 23;303(5657):540-3.

    Description: The whole-cell variant of the patch clamp technique was used to study calcium channels in GH3 cells. Two distinct populations of calcium channels, first recognized from their closing kinetics, were observed. The slowly closing channels are activated in a relatively negative voltage range and are inactivated within 100 milliseconds. They conduct barium and calcium about equally well. The fast closing channels are activated at more positive voltages, are not inactivated during a 100-millisecond pulse, conduct barium in preference to calcium, and are activated slightly more rapidly than the slowly closing channels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Armstrong, C M -- Matteson, D R -- New York, N.Y. -- Science. 1985 Jan 4;227(4682):65-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2578071" target="_blank"〉PubMed〈/a〉

    Description: The effects of calcium removal on the voltage-dependent potassium channels of isolated squid neurons were studied with whole cell patch-clamp techniques. When the calcium ion concentration was lowered from 10 to 0 millimolar (that is, no added calcium), potassium channel activity, identified from its characteristic time course, disappeared within a few seconds and there was a parallel increase in resting membrane conductance and in the holding current. The close temporal correlation of the changes in the three parameters suggests that potassium channels lose their ability to close in the absence of calcium and simultaneously lose their selectivity. If potassium channels were blocked by barium ion before calcium ion was removed, the increases in membrane conductance and holding current were delayed or prevented. Thus calcium is an essential cofactor in the gating of potassium channels in squid neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Armstrong, C M -- Lopez-Barneo, J -- New York, N.Y. -- Science. 1987 May 8;236(4802):712-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2437654" target="_blank"〉PubMed〈/a〉

    Description: We have measured the transmission spectrum of the extremely inflated hot Jupiter WASP-52b using simultaneous photometric observations in Sloan Digital Sky Survey u ', g ' and a filter centred on the sodium doublet (Na i ) with the ULTRACAM instrument mounted on the 4.2-m William Herschel Telescope. We find that Rayleigh scattering is not the dominant source of opacity within the planetary atmosphere and find a transmission spectrum more consistent with wavelength-independent opacity such as from clouds. We detect an in-transit anomaly that we attribute to the presence of stellar activity and find that this feature can be more simply modelled as a bright region on the stellar surface akin to solar faculae rather than spots. A spot model requires a significantly larger planet/star radius ratio than that found in previous studies. Our results highlight the precision that can be achieved by ground-based photometry with errors in the scaled planetary radii of less than one atmospheric scale height, comparable to Hubble Space Telescope observations.

    Notes: A compact, low cost gyrotron traveling-wave-tube (gyro-TWT) amplifier capable of producing high-power, broadband, millimeter wave radiation is reported. The interaction circuit is a periodic, magnetic field plane (H plane) bend, transverse folded waveguide employed with a high-power axis-encircling electron beam. Transverse beam modulation and wave amplification in the folded waveguide gyro-TWT are observed in both linear theory and large signal simulations. Calculations from an equivalent circuit model and a three-dimensional electromagnetic code predict a mode coalescing of the first stop-band in a periodic structure. The mode coalescing is verified from experimental measurements. © 1995 American Institute of Physics.

    Notes: Numerical simulations of a W-band two-stage tapered, frequency multiplied gyrotron- traveling-wave-tube amplifier are reported. Unlike conventional harmonic gyrodevices, a drive signal at the fundamental harmonic frequency is injected in the first stage for beam modulation, and amplified output radiation is extracted from the third harmonic cyclotron resonance interaction. Numerical results show that broadband millimeter wave radiation is obtained with an efficiency of 10%–15%, a gain of ∼30 dB, and an instantaneous bandwidth of ∼10% at a center frequency of 95 GHz for Δvz/vz=2%.

    Notes: Based on an equivalent circuit representation of a cavity impedance, a theoretical model of the cavity excitation by a modulated electron beam is developed. The beam current modulation is initiated by the first cavity and amplified in drift section between the first and second cavities. Properties of the second cavity excitation by the beam are described in terms of the phase shift Ψ and amplitude φ2 of induced voltage in the cavity. The phase shift Ψ and amplitude φ2 are determined in terms of the frequency difference (η), the cavity Q value, the voltage multiplication factor (χ), and magnitude (φ1) of the first cavity voltage. The voltage multiplication factor is proportional to the beam intensity, Q value, and distance between the first and second cavities. On the other hand, it is inversely proportional to frequency and capacitance of the cavity, and beam electron velocity. Because the induced voltage in the second cavity is in phase with the first cavity voltage at upshifted cavity frequency, amplitude of the current modulation at the upshifted frequency is larger than that at the downshifted cavity frequency. Experimental study is carried out by making use of a klystron amplifier operable from 4.4 to 5 GHz. Experimental data from the klystron agree remarkably well with amplifier performance profiles predicted by the theory.

    Notes: A linear analysis for a gyrotron backward wave oscillator operating at a general transverse electric (TEln) mode of a cylindrical waveguide (slotted or uniform cross section) has been developed using a Maxwell–Vlasov equation under the tenuous beam approximation. The equation is solved by Laplace transformation to allow easy insertion of the boundary values. The start-oscillations conditions are determined from an interference of the waveguide and beam modes with appropriate amplitudes and phases. The theory is used to determine the design parameters for stable operation of a second cyclotron harmonic gyropeniotron amplifier at 35 GHz in the π mode of a six vane magnetron-type circuit with a 70 kV, 3 A beam.
