Papel de las situaciones adidácticas en el aprendizaje matemático. Una mirada crítica desde el enfoque ontosemiótico
El postulado del aprendizaje por adaptación a un medio antagonista asumido por la teoría de situaciones didácticas en matemáticas se corresponde con el papel central que esta teoría atribuye a las situaciones adidácticas ... -
Partial representations of orderings
In the present paper a new concept of representability is introduced, which can be applied to not total and also to intransitive relations (semiorders in particular). This idea tries to represent the orderings in the ... -
Performance measures in dose-finding experiments
In the first phase of pharmaceutical development, and assuming that the probability of positive response increases with dose, the main statistical goal is to estimate a percentile of the dose–response function for a given ... -
Periodic solutions, KAM tori and bifurcations in a cosmology-inspired potential
A family of perturbed Hamiltonians H = 1/2 (x^2 + X^2) − 1/2 (y^2 + Y^2)+1/2 (z^2 + Z^2) + 2[ (x^4 + y^4 + z^4) + (x^2 y^2 + x^2 z^2 + y^2 z^2)] in 1: −1:1 resonance depending on two real parameters is considered. We ... -
Phenolic composition of grape stems from different Spanish varieties and vintages
Grape stems are a by‐product from the wine industry that has been underused to date despite having great potential for the agro‐food and cosmetic industries. The aim of the present work was to characterize grape stem ... -
Pinus spp. somatic embryo conversion under high temperature: effect on the morphological and physiological characteristics of plantlets
Climatic variations in the current environmental scenario require plants with tolerance to sudden changes in temperature and a decrease in water availability. Accordingly, this tolerance will enable successful plantations ... -
Police as first reponders improve out-of-hospital cardiac arrest survival
Background: Police forces are abundant circulating and might arrive before the emergency services to Out-of-Hospital-Cardiac-Arrest victims. If properly trained, they can provide basic life support and early defibrillation ... -
Predicting cancer incidence in regions without population-based cancer registries using mortality
Cancer incidence numbers are routinely recorded by national or regional population-based cancer registries (PBCRs). However, in most southern European countries, the local PBCRs cover only a fraction of the country. ... -
The problem of the last bed: contextualization and a new simulation framework for analyzing physician decisions
Faced with a full Intensive Care Unit (ICU), physicians need to decide between turning away a new patient in need of critical care and creating a vacancy by prematurely discharging a current occupant. This dilemma is widely ... -
Project and prototype of mobile application for monitoring the global COVID-19 epidemiological situation
The purpose of this research is to analyze currently available solutions that help to monitor the global epidemiological situation, including travel restrictions, as well as proposing a new solution dedicated to users who ... -
Projections and unconditional bases in direct sums of ℓp SPACES, 0<p≤∞
We show that every unconditional basis in a finite direct sum ⊕p∈Aℓp , with A ⊂ (0,∞], splits into unconditional bases of each summand. This settles a 40 years old question raised in 'A. Ortyński, Unconditional bases in ... -
Projections of lung cancer incidence by 2035 in 40 countries worldwide: population-based study
Background: The global burden of lung cancer (LC) is increasing. Quantitative projections of the future LC burden in different world regions could help optimize the allocation of resources and provide a benchmark for ... -
A proposal for tuning the α parameter in CαC-integrals for application in fuzzy rule-based classification systems
In this paper, we consider the concept of extended Choquet integral generalized by a copula, called CC-integral. In particular, we adopt a CC-integral that uses a copula defined by a parameter α, which behavior was tested ... -
Prostatic artery embolization (PAE) using polyethylene glycol microspheres: safety and efficacy in 81 patients
Purpose: To evaluate the safety and efficacy of prostatic artery embolization (PAE) using polyethylene glycol microspheres (PEGM) in patients with lower urinary tract symptoms secondary to benign prostatic hyperplasia ... -
Prostatic artery embolization versus transurethral resection of the prostate: a post hoc cost analysis of a randomized controlled clinical trial
Purpose: to perform a post hoc analysis of patient-incurred costs in a randomized controlled clinical trial comparing prostatic artery embolization (PAE) and transurethral resection of the prostate (TURP). Materials and ... -
Pseudo overlap functions, fuzzy implications and pseudo grouping functions with applications
Overlap and grouping functions are important aggregation operators, especially in information fusion, classification and decision-making problems. However, when we do more in-depth application research (for example, ... -
Psychosocial adjustment of in-home caregivers of family members with dementia and parkinson's disease: a comparative study
Neurodegenerative diseases such as Parkinson's and dementia are highly prevalent worldwide. People who suffer from these disorders often receive in-home care and assistance from family members, who must dedicate a considerable ... -
Quadcopter neural controller for take-off and landing in windy environments
(Elsevier, 2023) Artículo / ArtikuluaThis paper proposes the design of a quadcopter neural controller based on Reinforcement Learning (RL) for controlling the complete maneuvers of landing and take-off, even in variable windy conditions. To facilitate RL ... -
Quantifying external information in social network analysis: an application to comparative mythology
Social network analysis is a popular tool to understand the relationships between interacting agents by studying the structural properties of their connections. However, this kind of analysis can miss some of the domain-specific ... -
Quasi-greedy bases in ℓp (0 < p < 1) are democratic
The list of known Banach spaces whose linear geometry determines the (nonlinear) democracy functions of their quasi-greedy bases to the extent that they end up being democratic, reduces to c0, ℓ2, and all separable L1-spaces. ...
