Numerical simulations of the current channeling effect on MT responses due to shallow conductive structures
(Elsevier Science, 2003-12)
MT data obtained at an alluvial valley in Argentina showed a strong telluric current channeling along its axis. This effect was reflected in the MT curves as a very low response for the TM apparent resistivity for periods ...
Quantum Phase Transition Between One-channel and Two-channel Kondo Polarons
(American Physical Society, 2013-10)
For a mobile spin-1/2 impurity, coupled antiferromagnetically to a one-dimensional gas of fermions, perturbative ideas have been used to argue in favor of two-channel Kondo behavior of the impurity spin. Here we combine ...
Participation of membrane calcium channels in erythropoietin-induced endothelial cell migration
(Elsevier Gmbh, 2018-08)
Calcium (Ca2+) plays an important role in angiogenesis, as it activates the cell migration machinery. Different proangiogenic factors have been demonstrated to induce transient Ca2+ increases in endothelial cells. This has ...
Channelizing streams for agricultural drainage impairs their nutrient removal capacity
(American Society of Agronomy, 2019-03)
In agricultural basins, fluvial ecosystems can work as filters when retaining the nutrient excess from agricultural activities, mitigating the impacts downstream. In frequently flooded areas, like the Pampas Region of ...
Single-Channel Kinetic Analysis for Activation and Desensitization of Homomeric 5-HT3A Receptors
(Cell Press, 2009-09)
The 5-HT3A receptor is a member of the Cys-loop family of ligand-gated ion channels. To perform kinetic analysis, we mutated the 5-HT3A subunit to obtain a high-conductance form so that single-channel currents can be ...
Constitutive activity of the Ghrelin receptor reduces surface expression of voltage-gated Ca2+ channels in a CaVβ-dependent manner
(Company of Biologists, 2017-11)
Voltage-gated Ca2+ (CaV) channels couple membrane depolarization to Ca2+ influx, triggering a range ofCa2+-dependent cellular processes. CaV channels are, therefore, crucial in shaping neuronal activity and function, ...
Nicotinic receptor M3 transmembrane domain: Position 8′ contributes to channel gating
(American Society for Pharmacology and Experimental Therapeutics, 2002-08-01)
The nicotinic acetylcholine receptor (nAChR) is a pentamer of homologous subunits with composition α2βεδ in adult muscle. Each subunit contains four transmembrane domains (M1-M4). Position 8′ of the M3 domain is phenylalanine ...
Characterization of Sand Fraction Compounds (0,500mm/0,250mm) in the São Sebastião Channel, SPCaracterização dos Componentes da Fração Arenosa(0,500mm/0,250mm) no Canal de São Sebastião (SP)

Growth patterns of subaqueous depositional channel lobe systems developed over a basement with a downdip break in slope: Laboratory experiments
(Society for Sedimentary Geology, 2014-03)
A series of large-scale experiments on nonchannelized, depositional turbidity currents show the evolution and complex stratigraphy of channel-lobe systems developed updip and downdip of a break in slope. Two different sets ...
