Dynamical Systems Analysis of f(Q) Gravity
(MDPI, 2023-03-29)Modified gravity theories can be used for the description of homogeneous and isotropic cosmological models through the corresponding field equations. These can be cast into systems of autonomous differential equations ... -
Dynamical versions of Hardy's uncertainty principle: A survey
(American Mathematical Society, 2021-06-03)The Hardy uncertainty principle says that no function is better localized together with its Fourier transform than the Gaussian. The textbook proof of the result, as well as one of the original proofs by Hardy, refers to ... -

Dynamics and Spectroscopy with Neutrons—Recent Developments and Emerging Opportunities
(MDPI, 2021-04-29)This work provides an up-to-date overview of recent developments in neutron spectroscopic techniques and associated computational tools to interrogate the structural properties and dynamical behavior of complex and disordered ... -
Dynamics and structural features of biomolecules in aqueous environments - The cases of water and ice
(2021-12-01)tract La interacción del agua con los materiales biológicos es uno de los temas más emocionantes de la ciencia: la vida es imposible sin agua. Sin embargo, el agua en los seres vivos es muy diferente de lo que llamamos ... -
Dynamics of aqueous peptide solutions in folded and disordered states examined by dynamic light scattering and dielectric spectroscopy
(Royal Society of Chemistry, 2021-06-24)[EN] Characterizing the segmental dynamics of proteins, and intrinsically disordered proteins in particular, is a challenge in biophysics. In this study, by combining data from broadband dielectric spectroscopy (BDS) and ... -
Dynamics of biological and non-biological aqueous solutions-Evidence of coupling between the motions of water and solutes
(2017-06-21)Las proteínas son sistemas dinámicos que interactúan fuertemente con su entorno, de hecho, el propio disolvente es el que potencia los movimientos, aportando flexibilidad a la estructura de la molécula para que esta pueda ... -
Dynamics of carbon formation during the catalytic hydrodeoxygenation of raw bio-oil
(Royal Society of Chemistry, 2020-11-01)The formation, growth and transformation of the carbon residue (coke) deposited on the catalyst during the raw bio-oil hydrodeoxygenation have been studied. These deposits have a great impact on the overall process ... -
Dynamics of Confined Short-Chain alkanol in MCM-41 by Dielectric Spectroscopy: Effects of matrix and system Treatments and Filling Factor
(MDPI, 2020-03-07)The dynamics of n-propanol confined in regular MCM-41 matrix with the pore size Dpore = 40 Å, under various matrix conditioning and sample confining conditions, using broadband dielectric spectroscopy (BDS), is reported. ... -
Dynamics of diatomic molecules on metal surfaces: O2/Ag(110) and CO/Ru(0001)
(2017-01-25)This thesis concerns with theoretical modelling from first principles of dynamics of two gas-surface systems (oxygen on silver and carbon monoxide on ruthenium) that are relevant to the heterogeneous catalysis. An accurate ... -
Dynamics of Oxygen-Plankton Model with Variable Zooplankton Search Rate in Deterministic and Fluctuating Environments
(MDPI, 2022-05-11)It is estimated by scientists that 50–80% of the oxygen production on the planet comes from the oceans due to the photosynthetic activity of phytoplankton. Some of this production is consumed by both phytoplankton and ... -
Dynamics of pneumococcal nasopharyngeal carriage in healthy children attending a day care center in northern Spain. Influence of detection techniques on the results
(BioMed Central, 2012-03-22)Background: Pneumococcal nasopharyngeal carriage precedes invasive infection and is the source for dissemination of the disease. Differences in sampling methodology, isolation or identification techniques, as well as the ... -
Dynamics of responsible innovation constitution in European Union research policy: tensions, possibilities and constraints
(Edward Elgar, 2019)[EN]Over the past three decades, research policy in the European Union (EU) has increasingly taken on board criteria of responsibility, while actively promoting research and development (R & D) activities. However, these ... -
Dynamics of saturn's polar regions
