Anisotropy of the Electric Field Gradient in Two-Dimensional α-MoO3 Investigated by 57Mn(57Fe) Emission Mössbauer Spectroscopy
(MDPI, 2022-07-04)Van der Waals α-MoO3 samples offer a wide range of attractive catalytic, electronic, and optical properties. We present herein an emission Mössbauer spectroscopy (eMS) study of the electric-field gradient (EFG) anisotropy ... -
Annealing studies combined with low temperature emission Mössbauer spectroscopy of short-lived parent isotopes: Determination of local Debye–Waller factors
(American Institute of Physics, 2021-01)An extension of the online implantation chamber used for emission Mossbauer Spectroscopy (eMS) at ISOLDE/CERN that allows for quick removal of samples for offline low temperature studies is briefly described. We demonstrate ... -
Application of the k-Prototype Clustering Approach for the Definition of Geostatistical Estimation Domains
(MDPI, 2023-02-01)The definition of geostatistical domains is a stage in the estimation of mineral resources, in which a sample resulting from a mining exploration process is divided into zones that show homogeneity or minimal variation in ... -
Aspects of quality control of wind profiler measurements in complex topography
(Copernicus Gesellschaft, 2014)It is well known in the scientific community that some remote sensing instruments assume that sample volumes present homogeneous conditions within a defined meteorological profile. At complex topographic sites and under ... -
Assessing the suitability of the minimum capture size and protection regimes in the gooseneck barnacle shellfishery
(Elsevier, 2014-12-19)The suitability of a total-length-based, minimum capture-size and different protection regimes was investigated for the gooseneck barnacle Pollicipes pollicipes shellfishery in N Spain. For this analysis, individuals that ... -
Assessment of Biomass Energy Potential and Forest Carbon Stocks in Biscay (Spain)
(MDPI, 2016-03)The aim of this research is to identify, quantify and characterize the potential available forest biomass of Pinus radiata D. Don and Eucalyptus globulus Labill. across Biscay province in northern Spain. In order to do ... -
Assessment of the Evolution of End-Tidal Carbon Dioxide within Chest Compression Pauses to Detect Restoration of Spontaneous Circulation
(Public Library Of Science, 2021-05-18)Background Measurement of end-tidal CO2 (ETCO2) can help to monitor circulation during cardiopulmonary resuscitation (CPR). However, early detection of restoration of spontaneous circulation (ROSC) during CPR using ... -
BAMS: A Tool for Supervised Burned Area Mapping Using Landsat Data
(MDPI, 2014-12)A new supervised burned area mapping software named BAMS (Burned Area Mapping Software) is presented in this paper. The tool was built from standard ArcGIS (TM) libraries. It computes several of the spectral indexes most ... -
Bayesian network-based over-sampling method (BOSME) with application to indirect cost-sensitive learning
(Nature, 2022-05)Traditional supervised learning algorithms do not satisfactorily solve the classification problem on imbalanced data sets, since they tend to assign the majority class, to the detriment of the minority class classification. ... -
Brane nucleation in supersymmetric models
(Springer Nature, 2023-10-11)This paper explores the process of vacuum decay in supersymmetric models related to flux compactifications. In particular, we describe these instabilities within supersymmetric Lagrangians for a single three-form multiplet. ... -
Brillouin distributed sensor using RF shaping of pump pulses
(IOP, 2010)We introduce a novel configuration for long-range Brillouin optical time domain analysis (BOTDA) sensors that is based on shaping the pump pulses in the radio frequency instead of the optical domain. This results in a ... -
Brillouin spectral scanning using the wavelength dependence of the frequency shift
(IEEE, 2011)We present a novel Brillouin spectra characterization method based on the Brillouin frequency shift dependence with pump wavelength. It is applied to a Brillouin optical time domain analysis sensor, resulting in a cost ... -
Capnography: A support tool for the detection of return of spontaneous circulation in out-of-hospital cardiac arrest
(Elsevier, 2019-09)Background Automated detection of return of spontaneous circulation (ROSC) is still an unsolved problem during cardiac arrest. Current guidelines recommend the use of capnography, but most automatic methods are based ... -
Cardiac output estimation using ballistocardiography: a feasibility study in healthy subjects
(Nature, 2024)There is no reliable automated non-invasive solution for monitoring circulation and guiding treatment in prehospital emergency medicine. Cardiac output (CO) monitoring might provide a solution, but CO monitors are not ... -
Characterization of Chromatic Dispersion and Refractive Index of Polymer Optical Fibers
(MDPI, 2017-12-20)The chromatic dispersion and the refractive index of poly(methyl methacrylate) polymer optical fibers (POFs) have been characterized in this work by using a tunable femtosecond laser and a Streak Camera. The characterization ... -
