1. Causal dependencies and Shannon entropy budget -- Analysis of a reduced order atmospheric model

Abstract

The information entropy budget and the rate of information transfer between variables is studied in the context of a nonlinear reduced-order atmospheric model. The key ingredients of the dynamics are present in this model, namely the baroclinic and barotropic instabilities, the instability related to the presence of an orography, the dissipation related to the surface friction, and the large-scale meridional imbalance of energy. For the parameter chosen, the solutions of this system display a chaotic dynamics reminiscent of the large-scale atmospheric dynamics in the extra-tropics. The detailed information entropy budget analysis of this system reveals that the linear rotation terms plays a minor role in the generation of uncertainties as compared to the orography and the surface friction. Additionally, the dominant contribution comes from the nonlinear advection terms, and their decomposition in synergetic (co-variability) and single (impact of each single variable on the target one) components reveals that for some variables the co-variability dominates the information transfer. The estimation of the rate of information transfer based on time series is also discussed, and an extension of the Liang's approach to nonlinear observables, is proposed., Comment: 26 pages, 11 figures, 5 tables

Abstract

In this work, we investigate the physical aspects of the inflection-point inflation scenario and assess its observational viability in light of current Cosmic Microwave Background (CMB) data. The model we consider encapsulates the inflaton with a pseudo-scalar (the dark matter candidate) in a complex neutral scalar singlet. The cosmological constraints on the parameters of inflation derived at a high energy scale are translated to a low energy scale by running these parameters. Ensuring the entire Lagrangian to be invariant under a $Z_3$ symmetry with the adequate transformation of the fields, the imaginary part of the singlet decouples from the other scalars of the model. We then investigate if the observational viability of inflation is also compatible with this pseudo-scalar being the dark matter component.We show that the CMB constraints on the inflationary parameters assure that the pseudo-scalar is stable and provides the correct relic dark matter abundance only when the pseudo-scalar is thermally produced., Comment: This manuscript contains 17 pages, 17 figures and 3 tables.

3. A general theory to estimate Information transfer in nonlinear systems

Abstract

A general theory for computing information transfers in nonlinear stochastic systems driven by deterministic forcing and additive and/or multiplicative noises, is presented. It extends the Liang-Kleeman framework of causality inference to nonlinear cases based on information transfer across system variables (Liang, 2016). We present an effective method of computing formulas of the rates of Shannon entropy transfer (RETs) between selected causal and consequential variables, relying on the estimation from data of conditional expectations of the system forcing and their derivatives. Those expectations are approximated by nonlinear differentiable regressions, leading to a much easier and more robust way of computing RETs than the brute-force approach calling for numerical integrals over the state-space and the knowledge of the multivariate probability density of the system. The approach is fully adapted to the case where no model equations are available, starting with a nonlinear model fitting from data of the consequential variables, and the subsequent application of method to the fitted model. RETs are decomposed into sums of single one-to-one RETs plus synergetic terms (of pure nonlinear nature) accounting for the joint causal effect of groups of variables. State-dependent RET formulas are also introduced, showing where in state-space the entropy transfers and local synergies are more relevant. A comparison of the RETs estimations is performed with previous methods in the context of two models: (i) a model derived from a potential function and (ii) the classical chaotic Lorenz system, both forced by additive and/or multiplicative noises. The analysis demonstrates that the new estimations are robust, cheaper, and less data-demanding, providing evidence of the possibilities and generalizations offered by the method and opening new perspectives on real-world applications., Comment: 51 pages, 7 figures.

Abstract

We have witnessed a persistent puzzling anomaly in the muon magnetic moment that cannot be accounted for in the Standard Model even considering the large hadronic uncertainties. A new measurement is forthcoming, and it might give rise to a $5\sigma$ claim for physics beyond the Standard Model. Motivated by it, we explore the implications of this new result to five models based on the $SU(3)_C \times SU(3)_L \times U(1)_N$ gauge symmetry and put our conclusions into perspective with LHC bounds. We show that previous conclusions found in the context of such models change if there are more than one heavy particle running in the loop. Moreover, having in mind the projected precision aimed by the g-2 experiment at FERMILAB, we place lower mass bounds on the particles that contribute to muon anomalous magnetic moment assuming the anomaly is resolved otherwise. Lastly, we discuss how these models could accommodate such anomaly in agreement with existing bounds., Comment: 14 pages, 12 figures

19. Implementing the inverse type-II seesaw mechanism into the 3-3-1 model

High Energy Physics - Phenomenology
Abstract

After the LHC is turning on and accumulating more data, the TeV scale seesaw mechanisms for small neutrino masses in the form of inverse seesaw mechanisms are gaining more and more attention once they provide neutrino masses at sub-eV scale and can be probed at the LHC. Here we restrict our investigation to the inverse type II seesaw case and implement it into the framework of the 3-3-1 model with right-handed neutrinos. As interesting result, the mechanism provides small masses to both the standard neutrinos as well as to the right-handed ones. Its best signature are the doubly charged scalars which are sextet by the 3-3-1 symmetry. We investigate their production at the LHC through the process $\sigma (p\,p \rightarrow Z^*, \gamma^* ,Z^{\prime} \rightarrow \Delta^{++}\,\Delta^{--})$ and their signal through four leptons final state decay channel., Comment: 21 pages, 10 figures, minor changes, reference updated

25. Digital Twin for a Frequency Mixer Used as a Phase Sensor.

Author

Pires, Carlos, Abreu, Manuel, Godinho, Isabel, Agostinho, Rui, and Sousa, João A.

Abstract

The Portuguese Institute for Quality is responsible for the realization and dissemination of the frequency standard in Portugal. There are several techniques for frequency transfer, but we use a frequency mixer to detect phase variations between two light signals with different wavelengths, traveling along an optical fibre. In this paper, we present the development of a digital twin (DT) that replicates the use of a frequency mixer to improve the frequency transfer problem. A setup was built to train and validate the technique: a frequency mixer was used to determine the phase difference between the two signals, which are caused by temperature gradients in the fibre, together with real-time temperature data from sensors placed along the fibre and on the mixer itself. The DT was trained with two machine learning algorithms, in particular, ARIMA and LSTM networks. To estimate the accuracy of the frequency mixer working as a phasemeter, several sources of uncertainty were considered and included in the DT model, with the goal of obtaining a phase value measurement and its uncertainty in real time. The JCGM 100:2008 and JCGM 101:2008 approaches were used for the estimation of the uncertainty budget. With this work, we merge DT technology with a frequency mixer used for phase detection to provide its value and uncertainty in real time. [ABSTRACT FROM AUTHOR]

Abstract

We formulate a nonlinear synergistic theory of coevolutionary systems, disentangling and explaining dynamic complexity in terms of fundamental processes for optimised data analysis and dynamic model design: Dynamic Source Analysis (DSA). DSA provides a nonlinear dynamical basis for spatiotemporal datasets or dynamical models, eliminating redundancies and expressing the system in terms of the smallest number of fundamental processes and interactions without loss of information. This optimises model design in dynamical systems, expressing complex coevolution in simple synergistic terms, yielding physically meaningful spatial and temporal structures. These are extracted by spatiotemporal decomposition of nonlinearly interacting subspaces via the novel concept of a Spatiotemporal Coevolution Manifold. Physical consistency is ensured and mathematical ambiguities are avoided with fundamental principles on energy minimisation and entropy production. The relevance of DSA is illustrated by retrieving a non-redundant, synergistic set of nonlinear geophysical processes exerting control over precipitation in space and time over the Euro-Atlantic region. For that purpose, a nonlinear spatiotemporal basis is extracted from geopotential data fields, yielding two independent dynamic sources dominated respectively by meridional and zonal circulation gradients. These sources are decomposed into spatial and temporal structures corresponding to multiscale climate dynamics. The added value of nonlinear predictability is brought out in the geospatial evaluation and dynamic simulation of evolving precipitation distributions from the geophysical controls, using DSA-driven model building and implementation. The simulated precipitation is found to be in agreement with observational data, which they not only describe but also dynamically link and attribute in synergistic terms of the retrieved dynamic sources., Comment: 40 pages, 10 figures

Abstract

To alleviate challenges related to mobility, travel planning, and time management, individuals commonly encounter the necessity of locating points of interest (POIs) that either share the same physical building or are situated within interconnected buildings. However, existing search engines face difficulties in retrieving groups of places based on keywords and topological relations among their respective regions, for instance, when a user wants to find a residential building that is connected to a green area. This is primarily due to their limited consideration of POIs as mere points in space, rather than recognizing the polygonal geometries of their boundaries. In this work, we present a spatial search solution based on textual and topological query parameters for efficiently retrieving groups of POIs whose neighborhoods and boundaries satisfy specific restrictions. To perform this type of search efficiently, we propose the Topo‐MSJ algorithm, building upon the well‐established "Multi‐Star‐Join" (MSJ) algorithm, by including an efficient approach to handle queries with topological requirements. To assess the effectiveness of our solution, we conduct a performance evaluation by comparing the execution time of Topo‐MSJ with equivalent spatial SQL queries. The experimental analysis, performed on real datasets, reveals that Topo‐MSJ exhibits a faster execution time compared with equivalent SQL queries, additionally providing a simplified spatial pattern query notation.

Abstract

Background: Dependency is defined as a person's inability to meet basic human needs. In the context of aging, biopsychosocial changes compromise functionality, predisposing older adults to rely on others to perform daily activities. Fear of dependency describes the fear people have of appearing and/or being weak and/or reliant on others. The Fear of Dependency Scale (FDS), developed by Adams-Price and Ralston in 2016, aims to assess the fear of dependency by measuring an individual's attitudes toward being helped. Objective: This study presents a European Portuguese version of the FDS and examines its psychometric properties (internal consistency reliability and content validity). Methods: The translation and both cultural and linguistic adaptation of the FDS were performed by a panel of experts. A cross-sectional study was then performed to evaluate the psychometric properties (in terms of its reliability and validity) of the translated version of the FDS among a sample of 100 community-dwelling older adults. Results: The European Portuguese version of the FDS exhibited good psychometric properties. The scale's internal consistency was 0.84. Conclusions: The European Portuguese version of the FDS is a reliable, valid, and practical instrument for assessing the fear of dependency in older adults in the Portuguese population. It can be used in the context of health care provision and research. [ABSTRACT FROM AUTHOR]

Author

Cavalcanti, Elmano Ramalho, Pires, Carlos Eduardo, Cavalcanti, Elmano Pontes, and Pires, Vládia Freire

Abstract

Text mining has been used for various purposes, such as document classification and extraction of domain-specific information from text. In this paper we present a study in which text mining methodology and algorithms were properly employed for academic dishonesty (cheating) detection and evaluation on open-ended college exams, based on document classification techniques. Firstly, we propose two classification models for cheating detection by using a decision tree supervised algorithm. Then, both classifiers are compared against the result produced by a domain expert. The results point out that one of the classifiers achieved an excellent quality in detecting and evaluating cheating in exams, making possible its use in real school and college environments

47. The Contribution of Emotional Intelligence and Spirituality in Understanding Creativity and Entrepreneurial Intention of Higher Education Students

Author

Rodrigues, Ana Paula, Jorge, Filipa Eira, Pires, Carlos André, and António, Patrícia

Abstract

Purpose: The purpose of this paper is to analyse the role of spirituality and emotional intelligence in understanding creativity, attitudes towards entrepreneurship, perceived behavioural control (PBC) and entrepreneurial intention of students of a Portuguese higher education institution. A conceptual model is proposed representing direct and indirect relationships among these constructs. Design/methodology/approach: A quantitative approach was adopted in the form of a survey questionnaire applied to a sample of 345 university students. To test the hypothesised relationships between the constructs, the authors used the path analysis technique. Findings: Results show that personal attitudes towards entrepreneurship and PBC have a positive effect on entrepreneurial intention, and mediate the effect of emotional intelligence on entrepreneurial intention. Emotional intelligence has a direct positive effect on creativity. The results reveal no or a tenuous influence of spirituality in the various concepts studied. Practical implications: It is expected that the model can serve as a support for facilitating and promoting entrepreneurship in higher education environments. It could be of valuable use to furthering our understanding of the role of individual/psychological characteristics, motivational and attitudinal factors in fostering entrepreneurial intention of university students. Originality/value: Some studies suggest that psychological factors play an essential role in developing alternative models to the entrepreneurial process. However, the studies that directly explore how individual differences in emotional intelligence, spirituality and creativity relate to entrepreneurial intention are relatively few.

50. Lyapunov statistics and mixing rates for intermittent systems

Author

Subjects
Condensed Matter - Statistical Mechanics
Abstract

We consider here a recent conjecture stating that correlation functions and tail probabilities of finite time Lyapunov exponents would have the same power law decay in weakly chaotic systems. We demonstrate that this conjecture fails for a generic class of maps of the Pomeau-Manneville type. We show further that, typically, the decay properties of such tail probabilities do not provide significant information on key aspects of weakly chaotic dynamics such as ergodicity and instability regimes. Our approaches are firmly based on rigorous results, particularly the Aaronson-Darling-Kac theorem, and are also confirmed by exhaustive numerical simulations., Comment: 7 pages, 5 figures, to appear in PRE
