Orness for real m-dimensional interval-valued OWA operators and its application to determine a good partition
Ordered Weighted Averaging (OWA) operators are a profusely applied class of averaging aggregation functions, i.e. operators that always yield a value between the minimum and the maximum of the inputs. The orness measure ... -
Orness measurements for lattice m-dimensional interval-valued OWA operators
Ordered weighted average (OWA) operators are commonly used to aggregate information in multiple situations, such as decision making problems or image processing tasks. The great variety of weights that can be chosen to ... -
Orreagako elizan aurkitutako On Javier Ibarraren prediku bat Artzibarko hizkeran idatzirikoa
En este artículo se recogen unos sermones encontrados en la Colegiata de Roncesvalles/Orreaga, escritos por el canónigo de la misma Don Javier Ibarra (1876-1955). Este erudito (autor de varias monografías premiadas) ... -
Ortega y Gasset's reception through political contingences. A historiographical study in Spanish intellectual history
This article aims at analysing a particular case within Spanish historiography: how the writings, speeches and public activities of one of the greatest intellectuals of this country, the philosopher Jose Ortega y Gasset, ... -
Orthogonal basis for the optical transfer function
We propose systems of orthogonal functions qn to represent optical transfer functions (OTF) characterized by including the diffraction-limited OTF as the first basis function q0 OTF perfect. To this end, we apply a powerful ... -
Orthogonal basis with a conicoid first mode for shape specification of optical surfaces
A rigorous and powerful theoretical framework is proposed to obtain systems of orthogonal functions (or shape modes) to represent optical surfaces. The method is general so it can be applied to different initial shapes and ... -
Orthogonal basis with a conicoid first mode for shape specification of optical surfaces: reply
We present some comments to the paper 'Orthogonal basis with a conicoid first mode for shape specification of optical surfaces: comment'. -
Orthogonally polarized optical single sideband modulation for microwave photonics processing using stimulated Brillouin scattering
We present a novel technique to generate orthogonally polarized optical single sideband modulated signals. The modulation scheme is based on all optical stimulated Brillouin scattering processing of the optical carrier of ... -
Oscillatory motions in restricted N-body problems
We consider the planar restricted N-body problem where the N−1 primaries are assumed to be in a central configuration whereas the infinitesimal particle escapes to infinity in a parabolic orbit. We prove the existence of ... -
Oscillatory source tensor discriminant analysis (OSTDA): a regularized tensor pipeline for SSVEP-based BCI systems
Periodic signals called Steady-State Visual Evoked Potentials (SSVEP) are elicited in the brain by flickering stimuli. They are usually detected by means of regression techniques that need relatively long trial lengths to ... -
Otra forma de hacer la guerra en Navarra (1808-1814). Levantamiento armado o revolución
Ante el fracaso del ejército regular en Navarra y la ocupación del territorio por los franceses, surge la resistencia armada que será canalizada por las guerrillas, otra forma de hacer la guerra. La guerrilla requiere ... -
Outcomes for design and learning when teenagers with autism codesign a serious game: a pilot study
Digital educational games research tends to lack ecological validity by not adequately taking into account the views and perspectives of children and young people with autism spectrum disorders (ASD). This paper is a pilot ... -
Outstanding performance of rehydrated Mg-Al hydrotalcites as heterogeneous methanolysis catalysts for the synthesis of biodiesel
There is still a need for active, selective and stable heterogeneous catalysts for the synthesis of biodiesel. In this work, magnesium-aluminium hydrotalcites with Mg/Al molar ratios within the 1.5–5 range were synthesized ... -
Outstanding role of the magnetic entropy in arrested austenite in an ordered Ni45Mn36.7In13.3Co5 metamagnetic shape memory alloy
The relevance of the entropy and in particular the outstanding role of the magnetic contribution is analyzed in a non-equilibrium arrested austenite phase in a Ni 45 Mn 36.7 In 13.3 Co 5 metamagnetic shape memory alloy. ... -
Overall proportion of orthorexia nervosa symptoms: a systematic review and meta-analysis including 30 476 individuals from 18 countries
Background. To date, no previous meta-analysis has determined the overall proportion of orthorexia nervosa symptoms on a global scale. The aim of the present study was 2-fold: first, to establish the overall proportion ... -
Overcoming non-local effects and Brillouin threshold limitations in Brillouin optical time domain sensors
We demonstrate, for the first time to our knowledge, a Brillouin optical time domain analysis (BOTDA) sensor that is able to operate with a probe power larger than the Brillouin threshold of the deployed sensing fiber ... -
Overexpression of a pine Dof transcription factor in hybrid poplars: A comparative study in trees growing under controlled and natural conditions
In this work, the role of the pine transcriptional regulator Dof 5 in carbon and nitrogen metabolism has been examined in poplar trees. The overexpression of the gene and potential effects on growth and biomass production ... -
Overexpression of plastidial thioredoxin f leads to enhanced starch accumulation in tobacco leaves
Starch, the most abundant storage carbohydrate in plants, has been a major feedstock for first‐generation biofuels. Growing fuel demands require, however, that the starch yields of energy crops be improved. Leaf starch is ... -
Overexpression of plastidial thioredoxins f and m differentially alters photosynthetic activity and response to oxidative stress in tobacco plants
Plants display a remarkable diversity of thioredoxins (Trxs), reductases controlling the thiol redox status of proteins. The physiological function of many of them remains elusive, particularly for plastidial Trxs f and ... -
Overexpression of the recA gene decreases oral but not intraperitoneal fitness of Salmonella enterica
Transcription of the Salmonella enterica recA gene is negatively controlled by the LexA protein, the repressor of the SOS response. The introduction of a mutation (recAo6869) in the LexA binding site, in the promoter region ...
