Magnus integrators for linear and quasilinear delay differential equations
Elsevier (2023-04-29)A procedure to numerically integrate non-autonomous linear delay differential equations is presented. It is based on the use of a spectral discretization of the delayed part to transform the original problem into a matrix ... -
Mapping the Asymmetrical Citation Relationships Between Journals by h-Plots
Wiley (2014)I propose the use of h-plots for visualizing the asymmetric relationships between the citing and cited profiles of journals in a common map. With this exploratory tool, we can understand better the journal's dual roles of ... -
Mapping the intensity function of a non-stationary point process in unobserved areas
Springer (2022)Seismic networks provide data that are used as basis both for public safety decisions and for scientific research. Their configuration affects the data completeness, which in turn, critically affects several seismological ... -
Mark variograms for spatio-temporal point processes
Elsevier (2017)A spatio-temporal point process can be transformed into two marked point processes by taking the times or locations as marks. For these marked point processes mark variograms can be defined, opening a new way for the ... -
Mathematical Genesis of the Spatio-Temporal Covariance Functions
Science Publications (2011)Problem statement: Obtaining new and flexible classes of nonseparable spatio-temporal covariances have resulted in a key point of research in the last years within the context of spatiotemporal Geostatistics. Approach: ... -
Maximal regularity in l(p) spaces for discrete time fractional shifted equations
Elsevier (2017-09)In this paper, we are presenting a new method based on operator-valued Fourier multipliers to characterize the existence and uniqueness of p -solutions for discrete time fractional models i ... -
Mazur-Ulam type theorems for fuzzy normed spaces
International Scientific Research Publications (ISRP) (2017-08)In this paper, we provide Mazur-Ulam type results for (not necessarily surjective) maps preserving equality of fuzzy distance defined between two fuzzy normed spaces. Our main goal is to study the additivity of such ... -
Mean curvature of hypersurfaces in Killing submersionswith bounded shadow
Wiley (2020)Given a complete hypersurface isometrically immersed in an ambient manifold, in this paper we provide a lower bound for the norm of the mean curvature vector field of the immersion assuming that: 1) The ambient manifold ... -
Mean curvature, volume and properness of isometric immersions
American Mathematical Society (2017)We explore the relation among volume, curvature and properness of an m -dimensional isometric immersion in a Riemannian manifold. We show that, when the L p -norm of the mean curvature vector is bounded for ... -
Measure of Segments which Intersect a Convex Body from Rotational Formulae
Springer (2015-02)Classical problems in integral geometry and geometric probability involve the kinematic measure of congruent segments of fixed length within a convex body in ℝ3. We give this measure from rotational formulae; that is, from ... -
Measurement error models for spatial network lattice data: Analysis of car crashes in Leeds
Royal Statistical Society (2023-04-28)Road casualties represent an alarming concern for modern societies. During the last years, several authors proposed sophisticated approaches to help authorities implement new policies. These models were usually developed ... -
Method to determine which quantum operations can be realized with linear optics with a constructive implementation recipe
American Physical Society (2019)The evolution of quantum light through linear optical devices can be described by the scattering matrix S of the system. For linear optical systems with m possible modes, the evolution of n input photons is given by a ... -
Metrics and barycenters for point pattern data
Springer (2020)We introduce the transport–transform and the relative transport–transform metrics between finite point patterns on a generalspace, which provide a unified framework for earlier point pattern metrics, in particular the ... -
Minimal plane valuations
American Mathematical Society (AMS) (2018-07)We consider the value u(v)=lim m->m-1 a(mL) , where a(mL) is the last value of the vanishing sequence of Hº(mL) along a divisorial or irrational valuation v centered at Op2,p ,L (respectively, P ) being a line ... -
Modeling accident risk at the road level through zero-inflated negative binomial models: A case study of multiple road networks
Elsevier (2021-03-26)This paper presents a case study carried out in multiple cities of the Valencian Community (Spain) to determine the effect of sociodemographic and road characteristics on traffic accident risk. The analyzes are performed ... -
Modeling fire size of wildfires in Castellon (Spain), using spatiotemporal marked point processes
Elsevier (2016-12-01)The extent of fires, their periodicity and their impact on terrestrial communities have been a major con- cern in the last century. Wildfires play an important role in shaping landscapes and as a source of CO 2 and particulate ... -
Modeling infectious disease dynamics: Integrating contact tracing-based stochastic compartment and spatio-temporal risk models
Elsevier (2022)Major infectious diseases such as COVID-19 have a significant impact on population lives and put enormous pressure on healthcare systems globally. Strong interventions, such as lockdowns and social distancing measures, ... -
Modeling Influence of Soil Properties in Different Gradients of Soil Moisture: The Case of the Valencia Anchor Station Validation Site, Spain
Taylor and Francis (2021-12-19)The prediction of spatial and temporal variation of soil water content brings numerous benefits in the studies of soil. However, it requires a considerable number of covariates to be included in the study, complicating ... -
Modeling noisy time-series data of crime with stochastic differential equations
Springer (2022-11-01)We develop and calibrate stochastic continuous models that capture crime dynamics in the city of Valencia, Spain. From the emergency phone, data corresponding to three crime events, aggressions, stealing and women alarms, ... -
