In this work we present a simple and fast computational method, the visibility algorithm , that converts time series into graph. The constructed graph inherits several properties of in its structure. Thereby, periodic convert regular graphs, random do so graphs. Moreover, fractal scale-free networks, enhancing fact power law degree distributions are related to fractality, something highly discussed recently. Some remarkable examples analytical tools outlined test method's reliability. Many...

Fractional Brownian motion (fBm) has been used as a theoretical framework to study real-time series appearing in diverse scientific fields. Because of its intrinsic nonstationarity and long-range dependence, characterization via the Hurst parameter, H, requires sophisticated techniques that often yield ambiguous results. In this work we show fBm map into scale-free visibility graph whose degree distribution is function H. Concretely, it shown exponent power law depends linearly on This also...

Abstract MOTIVATION: To reconstruct metabolic pathways from biochemical and/or genome sequence data, the stoichiometric and thermodynamic feasibility of has to be tested. This is achieved by characterizing admissible region flux distributions in steady state. spanned what can called a convex basis. The concept 'elementary modes' provides mathematical tool define all routes that are feasible given network. In addition, we 'enzyme subsets' groups enzymes operate together fixed proportions...

Criminals are common to all societies. To fight against them the community takes different security measures as, for example, bring about a police. Thus, crime causes depletion of wealth not only by criminal acts but also because cost hiring police force. In this paper, we present mathematical model criminal-prone self-protected society that is divided into socio-economical classes. We study effect non-null rate on free-of-criminals which taken as reference system. As consequence, define one...

Abstract Current methodologies of genome‐wide single‐nucleotide polymorphism (SNP) genotyping produce large amounts missing data that may affect statistical inference and bias the outcome experiments. Genotype imputation is routinely used in well‐studied species to buffer impact downstream analysis, several algorithms are available fill genotypes. The lack reference haplotype panels precludes use these methods genomic studies on non‐model organisms. As an alternative, machine learning...

The structural properties of carbohydrate metabolism are being studied. present contribution focuses mainly on those processes involving the transfer carbon fragments among sugars. It is shown how enzymic activities fix way system self-organizes stoichiometrically at steady state. proven that there exists a specific correspondence between set all possible activities, activity set, and compatible flux distributions through pathway. On one hand, do not allow feasible coupling state reactions...

We consider growing interfaces as dynamical networks whose nodes are the discrete points of interface and edges physical interactions among them. map formed at each time into a graph by means visibility algorithm. As corresponding grow, their graphs change over time. show that all scale free for use variance node degrees measure properties these graphs. This magnitude reveals an unexpected scaling behaviour in both number enables to define three robust exponents characterize any type...

Gender-based crime is one of the most concerning scourges contemporary society, and governments worldwide have invested lots economic human resources to foretell their occurrence anticipate aggressions. In this work, we propose apply Machine Learning (ML) techniques create models that accurately predict recidivism risk a gender-violence offender. We feed model with data extracted from official Spanish VioGen system comprising more than 40,000 reports gender violence. To evaluate performance,...

Human societies are formed by different socio-economical classes which characterized their contribution to, and share of, the common wealth available. Cheaters, defined as those individuals that do not contribute to but benefit from it, have always existed, likely be present in all foreseeable future. Their existence brings about serious problems since they act sinks for community deplete resources limited often scarce. To fight cheaters, a society can invest additional pursue one or several...
