Effect of diameter on membrane capacity and conductance of sheep cardiac purkinje fibers
(Rockefeller University Press, 1975)
Membrane electrical properties were measured in sheep cardiac Purkinje fibers, having diameters ranging from 50 to 300/µm. Both membrane capacitance and conductance per unit area of apparent fiber surface varied fourfold ...
A beam model for duoskelion structures derived by asymptotic homogenization and its application to axial loading problems
(Elsevier Ltd.FR, 2023)
Duoskelion structures have been recently introduced by Barchiesi et al. (2021) as a proof-of-concept motif for a new class of metamaterials. The properties of these periodic beam-like chiral structural elements have been ...
Comparación de modelos de aprendizaje automático para la predicción de células cancerígenas a partir del complejo MHC I
(Escuela Colombiana de Ingeniería Julio GaravitoIngeniería Biomédica, 2020-05-22)
El presente trabajo propone una comparación de modelos de aprendizaje automático para la detección de células cancerígenas a partir de los antígenos del complejo MHC I. Utilizando protocolos de extracción de características ...
Estudo das propriedades de materiais supercondutores
(Universidade Estadual Paulista (Unesp), 2015)
Superconductivity was discovered by the dutch physicist Heike Kamerlingh Onnes (1853 1926) employing liquefied 4He to investigate the the behavior of the electrical resistance of a mercury (Hg) sample cooled until 4 K, ...
Diurnal variation of non-specular meteor trails
(European Geosciences Union, 2009-05-04)
We present results of simulated radar observations of meteor trails in an effort to show how non-specular meteor trails are expected to vary as a function of a number of key atmospheric, ionospheric and meteoroid parameters. ...
Fluorescence Quantum Yields in Complex Environments from QM-MM TDDFT Simulations: The Case of Indole in Different Solvents
(American Chemical Society, 2020-11)
Fluorescence is commonly exploited to probe microscopic properties. An important example is tryptophan in protein environments, where variations in fluorescence quantum yield, and in absorption and emission maxima, are ...
Antibacterial & antitubercular activities of cinnamylideneacetophenones
(2017-10-01)
Cinnamaldehyde is a natural product with broad spectrum of antibacterial activity. In this work, it was used as a template for design and synthesis of a series of 17 cinnamylideneacetophenones. Phenolic compounds 3 and 4 ...
Partial restoration of chiral symmetry in cold nuclear matter: the phi-meson case
(Iop Publishing Ltd, 2017-01-01)
The work presented at this workshop is divided into two parts. In the first part, the mass and decay width of the phi-meson in cold nuclear matter are computed in an effective Lagrangian approach. The medium dependence of ...
Estimation of chlorophyll-a concentration from optimizing a semi-analytical algorithm in productive inland waters
(2018-02-01)
The high nutrient concentrations coming from non-point and point pollution have been linked to algae blooms, especially in hydroelectric plant reservoirs, due to higher residence time compared to rivers. The monitoring of ...
