Children’s Drawing of Plant Life in the Time of COVID-19: An Analysis of the Changes Related to Content and Colour over a Two-Year Period
(MDPI, 2022)
[EN] This study analyses the depictions that a sample of young children completed to express their knowledge of plant life at two different times, two years apart. The pictorial content is examined by the complexity of the ...
A mathematical analysis of EDAs with distance-based exponential models
(Springer, 2022)
Estimation of Distribution Algorithms have been successfully used to solve permutation-based Combinatorial Optimization Problems. In this case, the algorithms use probabilistic models specifically designed for codifying ...
Analysis of the Refined Mean-Field Approximation for the 802.11 Protocol Model
(MDPI, 2022-11-12)
Mean-field approximation is a method to investigate the behavior of stochastic models formed by a large number of interacting objects. A new approximation was recently established, i.e., the refined mean-field approximation, ...
The Hajlasz Capacity Density Condition is Self-improving
(Springer, 2022)
We prove a self-improvement property of a capacity density condition for a nonlocal Hajlasz gradient in complete geodesic spaces with a doubling measure. The proof relates the capacity density condition with boundary ...
Automatic Analysis of Archimedes’ Spiral for Characterization of Genetic Essential Tremor Based on Shannon’s Entropy and Fractal Dimension
(MDPI, 2018-07)
Among neural disorders related to movement, essential tremor has the highest prevalence; in fact, it is twenty times more common than Parkinson's disease. The drawing of the Archimedes' spiral is the gold standard test to ...
The finitely generated Hausdorff spectra of a family of pro-p groups
(Elsevier, 2022-09)
Recently the first example of a family of pro-p groups, for p a prime, with full normal Hausdorff spectrum was constructed. In this paper we further investigate this family by computing their finitely generated Hausdorff ...
Meta-Analysis of the Embryo Freezing Transfer Interval
(Wiley, 2021-04)
Background The decision of whether frozen embryo transfer (FET) should be performed in the cycle immediately after OPU or at least one cycle later is controversial. FET could improve pregnancy rates in IVF; however, how ...
Approximate zero-crossing: a new interpretable, highly discriminative and low-complexity feature for EEG and iEEG seizure detection.
(IOP, 2022)
Objective. Long-term monitoring of people with epilepsy based on electroencephalography (EEG) and intracranial EEG (iEEG) has the potential to deliver key clinical information for personalised epilepsy treatment. More ...
Vortex Filament Equation for a Regular Polygon in the Hyperbolic Plane
(Springer, 2022-02)
The aim of this paper is twofold. First, we show the evolution of the vortex filament equation (VFE) for a regular planar polygon in the hyperbolic space. Unlike in the Euclidean space, the planar polygon is open and both ...
Children’s Pictorial Expression of Plant Life and Its Connection with School-Based Greenness
(MDPI, 2021-04-29)
Previous research highlights the positive influence that experiences in nature have on children’s physical, emotional and conceptual development. There is also evidence that indicates that the availability of green areas ...
