Modeling ionograms with deep neural networks: applications to foF2 forecasting
(Instituto Geofísico del Perú, 2021-06)
The ionosphere state parameters are of fundamental importance not only for radio communication but also for space weather. As most of the space phenomena, the dynamics are governed by nonlinear processes that make forecasts ...
Effect of the Inclusion of Solar Cycle 24 in the Calculation of foF2 Long-Term Trend for Two Japanese Ionospheric Stations
(Birkhauser Verlag Ag, 2019-08)
One of the main ionization sources of the F2 region of the Earth’s ionosphere is the solar EUV irradiance accounting for * 90% of its variability during quiet time. Consequently, prior to long-term trend estimations solar ...
Miedo a las caídas en las enfermedades neurodegenerativas de los ganglios basales : rol de la disfunción cognitiva, conductual y autonómica en la asociación entre la percepción de riesgo y el miedo a las caídas
(2021)
Resumen: Los pacientes con enfermedades neurodegenerativas de los ganglios basales (ENGB), constituyen un grupo de especial interés en el estudio del miedo a las caídas (FoF, por sus siglas en inglés), debido a que presentan ...
The shrimp mitochondrial FoF1-ATPase inhibitory factor 1 (IF1)
(Springer/Plenum Publishers, 2015-10)
The whiteleg shrimp species Litopenaeus vannamei is exposed to cyclic changes of the dissolved oxygen concentration of seawater and must neutralize the adverse effects of hypoxia by using ATP as energy source. In crustaceans, ...
foF2 long-term trends at the southern crest of the equatorial anomaly
(Elsevier Ltd., 2006-12)
Long-term trends in the electron density of the ionosphere for the period 1957-1986 is studied using foF2 monthly median hourly data measured at Tucuman (26.9S, 65.4W), a station located at the southern crest of the ...
Effect of solar cycle 23 in foF2 trend estimation
(Springer, 2014-09)
The effect of including solar cycle 23 in foF2 trend estimation is assessed using experimental values for Slough (51.5°N, 359.4°E) and Kokobunji (35.7°N, 139.5°E), and values obtained from two models: (1) the Sheffield ...
Imidacloprid affects rat liver mitochondrial bioenergetics by inhibiting FoF1-ATP synthase activity
(2018-04-18)
Imidacloprid (IMD) is a neonicotinoid insecticide widely used in crops, pets, and on farm animals for pest control. Several studies were conducted examining the adverse effects of IMD on animals often exhibiting hepatic ...
The representation of time variation of foF2 during geomagnetic storms
(Societá Italiana di Fisica, 2002-12)
In this paper a technique for describing the variations of the critical frequency of ionospheric F2-layer foF2 at middle latitudes during the 24 hours after geomagnetic storm sudden commencement is proposed, which serves ...
