Abortive and propagating intracellular calcium waves: Analysis from a hybrid model
(Public Library of Science, 2015-01)
The functional properties of inositol(1,4,5)-triphosphate (IP3) receptors allow a variety of intracellular Ca2+ phenomena. In this way, global phenomena, such as propagating and abortive Ca2+ waves, as well as local events ...
High altitude echoes from the equatorial topside ionosphere during solar minimum
(American Geophysical Union, 2021-02)
We describe a new class of nonthermal plasma density irregularities observed in the postmidnight topside equatorial ionosphere under low solar flux conditions. They are distinct from irregularities associated with equatorial ...
LOWER HYBRID ELECTRON-CYCLOTRON HEATING AND ASSOCIATED PARALLEL COOLING
(Iop Publishing LtdBristolInglaterra, 1991)
Paramagnetic collective electronic mode and low temperature hybrid modes in the far infrared dynamics of orthorhombic NdMnO3
(IOP Publishing, 2013-08)
We report on the far- and mid-infrared reflectivity of NdMnO3 from 4 to 300 K. Two main features are distinguished in the infrared spectra: active phonons in agreement with expectations for the orthorhombic ${\mathrm{D}} ...
Electron heating and acceleration by Alfven waves with varying phase velocity
(Royal Swedish Acad SciencesStockholmSuécia, 2000)
Artificial neural network performance evaluation for a hybrid power domain orthogonal/non-orthogonal multiple access (OMA/NOMA) system
(Association for Computing Machinery, Inc, 2020)
Next-generation wireless technologies face considerable challenges in terms of providing the required latency and connectivity for new heterogeneous mobile networks. Driven by these problems, this study focuses on increasing ...
Integration of silicon-based MMIC technology for millimeter wave cryogenic receivers.
(Universidad de Concepción.Departamento de Ingeniería EléctricaDepartamento de Ingeniería Eléctrica., 2021)
This thesis work is framed in the area of astronomical instrumentation, specifically
regarding the frequency range of millimeter wave. The demand for efficiency in
the astronomical observations of low noise requires the ...
Height variation of gaps in 150‐km echoes and whole atmosphere community climate model electron densities suggest link to upper hybrid resonance
(American Geophysical Union, 2020-01)
Radar echoes from the daytime lower F region near the magnetic equator, so-called 150-km echoes, have been puzzling researchers for decades. Neither the mechanisms that generate the enhanced backscatter at very high ...
