Abstract:

This paper defines the generalized wavelet Fisher information of parameterq. This information measure is obtained by generalizing the time-domain definition of Fisher’s information of Furuichi to the wavelet domain and allows to quantify smoothness and correlation, among other signals characteristics. Closed-form expressions of generalized wavelet Fisher information for1/fαsignals are determined and a detailed discussion of their properties, characteristics and their relationship with waveletq-Fisher information are given.

Abstract:

Diverse forms of nonlinearity within stochastic equations give rise to varying dynamics in processes, which may influence the behavior of extreme values. This study focuses on two nonlinear models of the discrete Langevin equation: one with a fixed diffusion function (M1) and the other with a fixed marginal distribution (M2), both characterized by a nonlinearity parameter. Extremes are defined according to the run theory with thresholds based on percentiles. The behavior of inter-extreme times and run lengths is examined by employing Fisher’s Information Measure and the Shannon Entropy. Our fi

Abstract:

The complexity measure for the distribution in space-time of a finite-velocity diffusion process is calculated. Numerical results are presented for the calculation of Fisher’s information, Shannon’s entropy, and the Cramér–Rao inequality, all of which are associated with a positively normalized solution to the telegrapher’s equation. In the framework of hyperbolic diffusion, the non-local Fisher’s information with the x-parameter is related to the local Fisher’s information with the t-parameter. A perturbation theory is presented to calculate Shannon’s entropy of the telegrapher’s equation at

Abstract:

In this work, we study quantum decoherence as reflected by the dynamics of a system that accounts for the interaction between matter and a given field. The process is described by an important information geometry tool: Fisher’s information measure (FIM). We find that it appropriately describes this concept, detecting salient details of the quantum–classical changeover (qcc). A good description of the qcc report can thus be obtained; in particular, a clear insight into the role that the uncertainty principle (UP) plays in the pertinent proceedings is presented.

Since the introduction of serial analysis of gene expression (SAGE) as a method to quantitatively analyze the differential expression of genes, several statistical tests have been published for the pairwise comparison of SAGE libraries.

At the same time, studies of instrumental records show that often the value of the dynamic gain does not depend on the values of peak accelerations.

A major problem is designing experiments when the assumed model is nonlinear, is the dependence of the designs on the values of the unknown parameters we consider in this article designs for binary data and generalize the constant information criterion suggested by Fisher (1922).

This leads to designs where dependence of Fisher’s information on the unknown parameters is very little, thus leading to constant variances. We show that such designs exist for any single parameter model, extending Fi

ABSTRACT BACKGROUND: The COVID-19 pandemic has changed digestive endoscopy services around the world. OBJECTIVE: This study aimed to measure the number of urgent/emergency endoscopic procedures performed in a Brazilian hospital, comparing it to the same period in the previous year, and to identify risk factors in COVID-19 patients undergoing endoscopic procedures for upper gastrointestinal bleeding (UGIB). METHODS: This was a retrospective, cross-sectional, observational, single-center study. The study evaluated urgent/emergency endoscopic procedures performed on adult patients from March to A

Promote knowledge of the diversity of Scarabaeidae: Scarabaeinae from Caquetá, Colombia. Methodology: Coprophagous beetles were collected using 50 Pitfall traps baited with human feces separated from each other by 10 meters. Each trap was active for 72 continuous hours. Species were classified according to the trophic guilds and three size categories. Sampling effort was explored using an accumulation curve, meanwhile, Hill numb

Integrating commercial and research surveys to estimate the harvestable biomass, and establish a quota, for an “unexploited” abalone population. – ICES Journal of Marine Science, 65: 1122–1130. A key challenge facing many fisheries managers is the absence of information on the level of harvestable biomass. We describe an integrated, two-stage survey approach that was used to measure the spatial distribution and harvestable biomass of a largely unexploited metapopulation of greenlip abalone (Haliotis laevigata) over a larg

Full text

Abstract:

Quantum synchronization has emerged as a crucial phenomenon in quantum nonlinear dynamics with potential applications in quantum information processing. Multiple measures for quantifying quantum synchronization exist. However, there is currently no widely agreed metric that is universally adopted. In this paper, we propose using classical and quantum Fisher information (FI) as alternative metrics to detect and measure quantum synchronization. We establish the connection between FI and quantum synchronization, demonstrating that both classical and quantum FI can be deployed as more general indi

Abstract:

Information on the catch composition and catchable size of lobsters in Lebak waters remains limited, posing challenges for effective fisheries management. This study aims to assess the technical performance of the lobster fishery and analyse catch composition. Data on technical performance were collected through interviews with fishers and lobster collectors using random sampling, while a census approach was applied to measure carapace length and weight for 589 lobsters. A descriptive quantitative analysis was conducted to evaluate the length-weight relationship of lobsters. The findings indic

Abstract:

In southern Benin, the rapid growth of demographics and the need for fishery products have forced public managers to adopt various management measures in the face of anti-ecological methods used by fishers; however, these strategies are often formulated independent from the context. These measures have not remained without consequence on the daily lives of fishers. This paper examines factors influencing fishers’ individual perceived wellbeing satisfaction using the social-ecological system framework. Data on 205 small-scale fishers’ demographic information, perception of job, and individual w

Abstract:

In this work, we define cumulative residual q-Fisher (CRQF) information measures for the survival function (SF) of the underlying random variables as well as for the model parameter. We also propose q-hazard rate (QHR) function via q-logarithmic function as a new extension of hazard rate function. We show that CRQF information measure can be expressed in terms of the QHR function. We define further generalized cumulative residual χ2 divergence measures between two SFs. We then examine the cumulative residual q-Fisher information for two well-known mixture models, and the corresponding results
