Off-line writer verification using segments of handwritten samples and SVM
; ; Mora, Marco
(2021)
This works presents a method to verify a person identity based on off-line handwritten strokes analysis. Its main contribution is that the descriptors are obtained from the constitutive segments of each grapheme, in contrast ...

On a logistic regression model with random intercept: diagnostic analytics, simulation and biological application
(2020)This article proposes a methodology for diagnostics in a logistic regression with random intercept motivated by a biological study. The methodology includes local and global influence techniques allowing us to contrast the ...

On a partial least squares regression model for asymmetric data with a chemical application in mining
(2019)In chemometrical applications, covariates in regression models are often correlated, causing a collinearity problem that can be solved by partial least squares (PLS) regression. In addition, high dimensionality in the space ...

On existence of semi-wavefronts for a non-local reaction–diffusion equation with distributed delay
(2018)We study the problem of existence of semi-wavefront solutions for a non-local delayed reaction–diffusion equation with monostable nonlinearity. In difference with previous works, we consider non-local interaction which can ...

On pharmacological neuroenhancement as part of the new neurorights' pioneering legislation in Chile: a perspective
(2023)The so-called neurorights are emerging human rights, or rather reconfigurations of already existing human rights, seeking to address the impact of the possible misuse of neurotechnologies, which have the potential to become ...

On some goodness-of-fit tests and their connection to graphical methods with uncensored and censored data
(2020)In this work, we present goodness-of-fit tests related to the Kolmogorov-Smirnov and Michael statistics and connect them to graphical methods with uncensored and censored data. The Anderson-Darling test is often empirically ...

On the nature of the enzyme–substrate complex and the reaction mechanism in human Arginase I. A combined molecular dynamics and QM/MM study
(2020)We present here a complete detailed theoretical analysis of l-arginine hydrolysis catalyzed by human arginase I (HARGI). Our study combines classical molecular dynamics (MD) simulations of different models for the ...

On the performance of MIMO-VLC techniques in underground mining environments
(2023)Underground mining visible light communication (UM-VLC) is a promising solution to ensure the well-being of workers and facilitate their work. However, underground conditions present a significant divergence from widely ...

On the relationship between language learning strategies and language proficiency in indian universities
(2021)Language learning strategies (LLS) research began in the mid-1970s with the main idea of individual differences in learning a foreign language focusing primarily on the characteristics of a good language learner. In the ...

On the role of social media in spanish language learning in indian context
(2022)Research on social media in the foreign language classroom has grown significantly in the last decade. The usage of social media has increased many times during the pandemic due to known reasons. The aim of the present ...

On the tractability of shortest path problems in weighted edge-coloured graphs
(2018)A weighted edge-coloured graph is a graph for which each edge is assigned both a positive weight and a discrete colour, and can be used to model transportation and computer networks in which there are multiple transportation ...

On the uniqueness of semi-wavefronts for non-local delayed reaction–diffusion equations
(2015)We establish the uniqueness of semi-wavefront solution for a non-local delayed reaction–diffusion equation. This result is obtained by using a generalization of the Diekmann–Kaper theory for a nonlinear convolution equation. ...

On uniqueness of semi-wavefronts: Diekmann–Kaper theory of a nonlinear convolution equation re-visited
(2012)Motivated by the uniqueness problem for monostable semi-wave -fronts, we propose a revised version of the Diekmann and Kaper theory of a nonlinear convolution equation. Our version of the Diekmann–Kaper theory allows (1) ...

One-week suicide risk prediction using real-time smartphone monitoring: prospective cohort study
(2023)Background: Suicide is a major global public health issue that is becoming increasingly common despite preventive efforts. Though current methods for predicting suicide risk are not sufficiently accurate, technological ...

Onset of schizophrenia diagnoses in a large clinical cohort
(2019)We aimed to describe the diagnostic patterns preceding and following the onset of schizophrenia diagnoses in outpatient clinics. A large clinical sample of 26,163 patients with a diagnosis of schizophrenia in at least one ...

Operacionalización del modelo función-disfunción: Un acercamiento hacia la "pretensión" de la autonomía profesional
(2011)La disponibilidad de un modelo epistemológico que permita orientar una mejor práctica, es una necesidad que demanda la exposición transparente de las bases teóricas que lo sostienen en diversos contextos con el fin de ...
