First-principles calculations of hot-electron lifetimes in metals
(American Physical Society, 2000)First-principles calculations' of the inelastic lifetime of low-energy electrons in Al, Mg, Be, and Cu are reported. Quasiparticle damping rates are evaluated from the: knowledge of the electron self-energy, which we compute ... -
El Fiscal como autoridad judicial de emisión de "euro-órdenes" a la luz de las sentencias del Tribunal de Justicia de 27 e mayo de 2019 en el asunto C-509/18 y en los asuntos acumulados C-508/18 y C-82/19 PPU ¿Un paso definitivo en su concreción?
(Iustel, 2019-10)El autor analiza en profundidad las sentencias de 27 de mayo de 2019 del Tribunal de Justicia en las que se desarrolla la interpretación del concepto de «autoridad judicial emisora» del artículo 6.1 de la Decisión marco ... -
Fishing diseased abalone to promote yield and conservation
(The Royal Society Publishing, 2016)Past theoretical models suggest fishing disease-impacted stocks can reduce parasite transmission, but this is a good management strategy only when the exploitation required to reduce transmission does not overfish the ... -
Fishing effort validation and substitution possibilities among components: the case study of the VIII division European anchovy fishery
(Routledge. Taylor & Francis, 2003)Command and control regulation programs, particularly input constraints, typically fail to achieve stated objectives, because fishermen may substitute unregulated for regulated inputs. It is, thus, essential to have an ... -
Fishing Long-Fingered Bats (Myotis capaccinii) Prey Regularly upon Exotic Fish
(Public Library of Science, 2013-11-27)The long-fingered bat Myotis capaccinii is a European trawling bat reported to feed on fish in several Mediterranean locations, but the ecological circumstances of this behavior have not yet been studied. To elucidate the ... -
Fishing Technique of Long-Fingered Bats Was Developed from a Primary Reaction to Disappearing Target Stimuli
(Public Library Science, 2016-12-14)Behavioral plasticity is a key feature allowing animals to broaden their dietary niche when novel food resources become available, and long-fingered bats provide an appropriate model system to study the underpinnings of ... -
Fit-for-purpose based testing and validation of antibodies to amino- and carboxy-terminal domains of cannabinoid receptor 1
(Springer, 2021-11)Specific and selective anti-CB1 antibodies are among the most powerful research tools to unravel the complex biological processes mediated by the CB1 receptor in both physiological and pathological conditions. However, low ... -
Fitting BICEP2 with defects, primordial gravitational waves and dust
(IOP Publishing, 2015)In this work we discuss the possibility of cosmic defects being responsible for the B-mode signal measured by the BICEP2 collaboration. We also allow for the presence of other cosmological sources of B-modes such as ... -
Five MegawattWind Turbine Power Output Improvements by Passive Flow Control Devices
(MDPI, 2017-06)The effects of two types of flow control devices, vortex generators (VGs) and Gurney flaps (GFs), on the power output performance of a multi-megawatt horizontal axis wind turbine is presented. To that end, an improved blade ... -
Five Patients with Disorders of Calcium Metabolism Presented with GCM2 Gene Variants
(Nature, 2021-02-03)The GCM2 gene encodes a transcription factor predominantly expressed in parathyroid cells that is known to be critical for development, proliferation and maintenance of the parathyroid cells. A cohort of 127 Spanish patients ... -
Five Years (2014–2018) of Beta Activity Concentration and the Impact of Synoptic and Local Meteorological Conditions in Bilbao (Northern Spain)
(MDPI, 2021-10-10)The aim of this paper is to statistically characterize gross beta activity concentrations in ground-level air in Bilbao (northern Spain) by analysing five years (2014–2018) worth of weekly measurements in aerosols collected ... -
Five-Axis Milling of Large Spiral Bevel Gears: Toolpath Definition, Finishing, and Shape Errors
(MDPI, 2018-05)In this paper, a five-axis machining process is analyzed for large spiral-bevel gears, an interesting process for one-of-kind manufacturing. The work is focused on large sized spiral bevel gears manufacturing using universal ... -
Five-year follow-up mortality prognostic index for colorectal patients
(Springer, 2023-03)Purpose To identify 5-year survival prognostic variables in patients with colorectal cancer (CRC) and to propose a survival prognostic score that also takes into account changes over time in the patient’s health-related ... -
Fixed and Best Proximity Points of Cyclic Jointly Accretive and Contractive Self-Mappings
(Hindawi Publishing Corporation, 2012)p(>= 2)-cyclic and contractive self-mappings on a set of subsets of a metric space which are simultaneously accretive on the whole metric space are investigated. The joint fulfilment of the p-cyclic contractiveness and ... -
Fixed Point and Best Proximity Theorems under Two Classes of Integral-Type Contractive Conditions in Uniform Metric Spaces
(Hindawi Publishing Corporation, 2010)This paper investigates the existence of fixed points and best proximity points of p-cyclic self-maps on a set of subsets of a certain uniform space under integral-type contractive conditions. The parallel properties of ... -
Fixed point approach to the Mittag-Leffler kernel-related fractional differential equations
(AIMS Press, 2023-02)The goal of this paper is to present a new class of contraction mappings, so-called -contractions. Also, in the context of partially ordered metric spaces, some coupled fixed-point results for -contraction mappings are ... -
