(OPTICAL SOC AMER, 2012-02-15)We investigate experimentally the light evolution inside a two-dimensional finite periodic array of weakly coupled optical waveguides with a disordered boundary. For a completely localized initial condition away from the ...
-
(AMER PHYSICAL SOC, 2012-01-31)We investigate numerically the effect of the competition of disorder, nonlinearity, and boundaries on the Anderson localization of light waves in finite-size, one-dimensional waveguide arrays. Using the discrete ...
-
(AMER PHYSICAL SOC, 2012-02-13)We introduce a novel concept of surface bound states in the continuum, i.e., surface modes embedded into the linear spectral band of a discrete lattice. We suggest an efficient method for creating such surface modes and ...
-
(PONTIFICIA UNIVERSIDAD CATOLICA CHILE, FAC AGRONOMIA INGENIERIA FORESTAL, 2012-04)Flowering traits are becoming important breeding objectives in Eucalyptus cladocalyx. Previous studies have confirmed that the trees from Cowell, Australia, respond well for early flowering under the arid conditions in ...
-
(Springer, 2012-02)One promising public health intervention for promoting physical activity is the Ciclovia program. The Ciclovia is a regular multisectorial community-based program in which streets are temporarily closed for motorized ...
-
(BIOMED CENTRAL LTD, 2012-01-03)Background: The increasing number of developmental events and molecular mechanisms associated with the Hedgehog (Hh) pathway from Drosophila to vertebrates, suggest that gene regulation is crucial for diverse cellular ...
-
(Elsevier, 2012)In some archaea, glucose degradation proceeds through a modified version of the Embden-Meyerhof pathway where glucose and fructose-6-P phosphorylation is carried out by kinases that use ADP as the phosphoryl donor. Unlike ...
-
(AMER PHYSICAL SOC, 2012-01-04)We study discrete surface solitons in semi-infinite, one-dimensional, nonlinear (Kerr), quasiperiodic waveguide arrays of the Fibonacci and Aubry-Andre types, and explore different families of localized surface modes, as ...
-
(2012-01-18)When a salient object in the visual field captures attention, the neural representation of that object is enhanced at the expense of competing stimuli. How neural activity evoked by a salient stimulus evolves to take ...
-
(TAYLOR & FRANCIS, 2012)Hybrid two-dimensional nanocomposites of transition metal semiconductors based on molybdenum disulfide, zinc oxide, and vanadium pentoxide, in which ultra-thin sheets of the inorganic component are stabilized by insertion ...
-
(Elsevier Ltd., 2009-05-19)Several cytisine derivatives have been developed in the search for more selective drugs at nicotinic acetylcholine receptors (nAChR). Binding experiments in transfected cell lines showed that the iodination of cytisine ...

(Nature Publishing Group, 2004-02-04)1 We recently described that several 2-(2,5-dimethoxy-4-substituted phenyl)ethylamines (PEAs), including 4-I¼2C-I, 4-Br¼2C-B, and 4-CH3¼2C-D analogs, are partial agonists at 5-HT2C receptors, and show low or even negligible ...
-
(Elsevier Ltd., 2009-02-08)A series of naphthylisopropylamine and N-benzyl-4-methylthioamphetamine derivatives were evaluated as monoamine oxidase inhibitors. Their potencies were compared with those of a series of amphetamine derivatives, to test ...
-
(AMER CHEMICAL SOC, 2012-02)Myelination is a highly regulated developmental process whereby oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system ensheathe axons with a multilayered concentric membrane. ...
-
(Kluwer Academic Publishers, 2002-03-05)The HOMO energies and the charges on the aromatic carbons of two sets of MAO-A-inhibiting phenylisopropylamines, one containing 4-amino substituents, were calculated by the AM1 method, in order to evaluate the importance ...
-
(Georg Thieme, 2004-03-14)We have studied the mechanism of action of three 6a( R)-1,2-methylenedioxyaporphines as vasorelaxant compounds. The alkaloids assayed showed different affinities for the three human cloned alpha (1)-adrenoceptor (AR) ...
