On the evidence for prelinguistic concepts
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2005)... -
On the Existence of Equilibrium Points, Boundedness, Oscillating Behavior and Positivity of a SVEIRS Epidemic Model under Constant and Impulsive Vaccination
(Hindawi Publishing Corporation, 2011)This paper discusses the disease-free and endemic equilibrium points of a SVEIRS propagation disease model which potentially involves a regular constant vaccination. The positivity of such a model is also discussed as well ... -
On the Extensions of Krasnoselskii-Type Theorems to p-Cyclic Self-Mappings in Banach Spaces
(Hindawi Publishing Corporation, 2011)A set of np(>= 2)-cyclic and either continuous or contractive self-mappings, with at least one of them being contractive, which are defined on a set of subsets of a Banach space, are considered to build a composed self-mapping ... -
On the External Positivity of SISO Linear Dynamic Systems under a Class of Nonzero and Possibly Negative Initial Conditions Eventually Subject to Incommensurate Point Internal and External Delays
(MDPI, 2022-01-25)The property of external positivity of dynamic systems is commonly defined as the non-negativity of the output for all time under zero initial conditions and any given non-negative input for all time. This paper investigates ... -
On the friability of mussel shells as abrasive
(Elsevier, 2022-11)The spread of raft-farming of mussels in river estuaries around the world produces about 1.4 million tons of shell waste which mainly ends up in landfills. In addition, the United Nations and the European Union promote the ... -
On the Global Asymptotic Stability of Switched Linear Time-Varying Systems with Constant Point Delays
(Hindawi Publishing Corporation, 2008)This paper investigates the asymptotic stability of switched linear time-varying systems with constant point delays under not very stringent conditions on the matrix functions of parameters. Such conditions are their ... -
On the Hermeneutic Alternative to Normative Naturalism
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 1999)... -
On the human evaluation of universal audio adversarial perturbations
(Elsevier, 2022-01)[EN] Human-machine interaction is increasingly dependent on speech communication, mainly due to the remarkable performance of Machine Learning models in speech recognition tasks. However, these models can be fooled by ... -
On the impact of independence of irrelevant alternatives: the case of two-person NTU games
(Springer, 2012-03)On several classes of n-person NTU games that have at least one Shapley NTU value, Aumann characterized this solution by six axioms: Non-emptiness, efficiency, unanimity, scale covariance, conditional additivity, and ... -
On the influence of conformity on wheel–rail rolling contact mechanics
(Elsevier, 2016-07)The aim of this work is to assess the effects of conformity on local contact related quantities at the wheel–rail interface such as traction distributions, subsurface stresses and frictional work distributions. For this ... -
On the Influence of Infra-Red Sensor in the Accurate Estimation of Grinding Temperatures
(MDPI, 2018-11-26)Workpiece rejection originated by thermal damage is of great concern in high added-value industries, such as automotive or aerospace. Surface temperature control is vital to avoid this kind of damage. Difficulties in ... -
On The Influence of Rotary Dresser Geometry on Wear Evolution and Grinding Process
(MDPI, 2019-11-22)Dressing is a critical issue for optimizing the grinding process. Dresser tool and dresser parameters must be designed according to the grinding wheel material, shape, or even the dimensional and geometrical tolerances ... -
On the Informational Role of Term Structure in the U.S. Monetary Policy Rule
(University of the Basque Country, Department of Foundations of Economic Analysis II, 2010-01)This paper uses a structural approach based on the indirect inference principle to estimate a standard version of the new Keynesian monetary (NKM) model augmented with term structure using both revised and real-time data. ... -
On the interaction of velars and labials
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2007)The paper treats data from a wide range of languages to show, on the one hand, that there is pervasive direct interaction between labials and velars to the exclusion of coronals, and, on the other hand, that the drive ... -
On the Interplay Between Logic and Philosophy: A Historical Perspective
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 1993)... -
On the Interpretation of Formal Languages and the Analysis of Logical Properties
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2000)... -
On the linearized system of equations for the condensate–normal fluid interaction at very low temperature
(Wiley, 2023-02)The linearization around one of its equilibrium of a system that describes the correlations between the superfluid component and the normal fluid part of a condensed Bose gas in the approximation of very low temperature ... -
On the links between limit characteristic zeros and stability properties of linear time-invariant systems with point delays and their delay-free counterparts
(Hindawi Publishing Corporation, 2004)We investigate the relationships between the infinitely many characteristic zeros (or modes) of linear systems subject to point delays and their delay-free counterparts based on algebraic results and theory of analytic ... -
On the links between nature's values and language
(People and Nature, 2023)Recent research into the plural values about nature is focusing on relational values as a concept through which to better understand the breadth and importance of situated human–nature relations. However, potential relevance ... -
On the Locus of L2 Lexical Fuzziness: Insights From L1 Spoken Word Recognition and Novel Word Learning
(Frontiers in Psychology, 2021)The examination of how words are learned can offer valuable insights into the nature of lexical representations. For example, a common assessment of novel word learning is based on its ability to interfere with other ...
