A general photon source model for clinical linac heads in photon mode.
(Elsevier, 2015)In this work a general photon source model has been developed to describe clinical linac heads when operating in photon mode. Six different linacs (three operating at 6 MV, one at 15 MV and two at 18 MV) have been studied. ... -
A mechanism for the multidecadal modulation of ENSO teleconnection with Europe.
(Springer, 2014-10-26)El Niño phenomenon is the main oceanic driver of the interannual atmospheric variability and a determi- nant source of predictability in the tropics and extratrop- ics. Several studies have found a consistent and statisti- ... -
A Review of ENSO Influence on the North Atlantic. A Non-Stationary Signal
(MDPI journals, 2016-06-25)The atmospheric seasonal cycle of the North Atlantic region is dominated by meridional movements of the circulation systems: from the tropics, where the West African Monsoon and extreme tropical weather events take place, ... -
A source model for the electron contamination of clinical linac heads in photon mode.
(IOP, 2015-07-30)In this work a general source model has been developed to describe the electron contamination in clinical linac heads when operating in photon mode. The model includes two-sources that take into account the electrons ... -
AC Electrokinetic of Salt-Free Multilayered Polymer-Grafted Particles.
(MDPI, 2020)Interest in the electrical properties of the interface between soft (or polymer-grafted) nanoparticles and solutions is considerable. Of particular significance is the case of polyelectrolyte-coated particles, mainly ... -
Aerosol transmittance for clear-sky solar irradiance models: Review and validation of an accurate universal parameterization
(Elsevier, 2021-04-26)Accurate modeling of solar radiation under cloudless situations is important to facilitate the development and exploitation of the renewable solar resource worldwide. However, many existing clear-sky solar radiation models ... -
Band Gap Narrowing versus Formation of Electronic States in the Gap in N-TiO2 Thin Films.
(ACS, 2010-12-02)N-containing TiO2 thin films with different amounts of nitrogen have been prepared by plasma enhanced chemical vapor deposition (PECVD) by using different titanium precursors without (titanium isopropoxide, TTIP) and ... -
CAELUS: Classification of sky conditions from 1-min time series of global solar irradiance using variability indices and dynamic thresholds
(Elsevier, 2023-08-12)Precise sky classification as a function of cloudiness is desirable or necessary in a variety of applications. CAELUS, a novel classification algorithm that relies on various thresholds to separate all possible sky conditions ... -
Carbon and oxygen minibeam radiation therapy: An experimental dosimetric evaluation
(Wiley, 2017-05-29)Abstract Purpose: To perform dosimetric characterization of a minibeam collimator in both carbon and oxygen ion beams to guide optimal set up geometry and irradiation for future radiobiological studies using these ... -
Chemical State of Nitrogen and Visible Surface and Schottky Barrier Driven Photoactivities of N-Doped TiO2 Thin Films.
(ACS, 2009-07-07)N-doped TiO2 thin films have been prepared by plasma enhanced chemical vapor deposition and by physical vapor deposition by adding nitrogen or ammonia to the gas phase. Different sets of N-doped TiO2 thin films have been ... -
Dynamic viscosity of colloidal silica suspensions at low and high volume fractions.
(Elsevier, 2018)A comprehensive study was carried out on the dynamic viscosity of X30 silica dispersions at both high and low volume fractions of colloidal silica particles at various electrolyte ionic strength and pH values. Booth and ... -
Effects of finite counterion size and nonhomogeneous permittivity and viscosity of the solution on the electrokinetics of a concentrated salt-free colloid
(American Physical Society (APS), 2024)In the present work, a general model of the electrokinetics and dielectric response of a concentrated salt-free colloid is developed which includes consideration of the finite size of the counterions released by the particles ... -
Electrochemical characterization of charged membranes from different materials and structures by membrane potential analysis.
(MDPI, 2023-08-17)Electrochemical characterization of positively and negatively charged membranes is performed by analyzing membrane potential values on the basis of the Teorell–Meyer–Sievers (TMS) model. This analysis allows the separate ... -
Electrokinetic and dielectric response of a concentrated salt-free colloid: Different approaches to counterion finite size effects.
(American Physical Society (APS), 2022)In the present work, a general model is developed for the electrokinetics and di- electric response of a concentrated salt-free colloid that takes into account the finite size of the counterions released by the particles ... -
Electrokinetic detection of the salt-free condition in colloids. Application to polystyrene latexes.
(Elsevier, 2022)Because of their singular phenomenology, the so-called salt-free colloids constitute a special family of dispersed systems. Their main characteristic is that the dispersion medium ideally contains only the solvent and the ... -
ENSO influence on the North Atlantic European climate: A non-linear and non-stationary approach
(Springer, 2015-12-29)ENSO impact on the North Atlantic European sector (NAE) is still under discussion. Recent studies have found a non stationary feature of this teleconnection, suggesting an effective modu- lating role of the ocean mean ... -
ENSO Influence on Western European Summer and Fall Temperatures.
(American Meteorological Society, 2021)In certain regions, such as Europe, the increase in global air temperatures in the world is translated into more frequent extreme events. Recent studies suggest that the increasing intensity in heatwaves seems to be related ... -
