Unfolding the distribution of periodicity regions and diversity of chaotic attractors in the Chialvo neuron map.

We performed an exhaustive numerical analysis of the two-dimensional Chialvo map by obtaining the parameter planes based on the computation of periodicities and Lyapunov exponents. Our results allowed us to determine the different regions of dynamical behavior, identify regularities in the distribution of periodicities in regions indicating regular behavior, find some pseudofractal structures, identify regions such as the "eyes of chaos" similar to those obtained in parameter planes of continuous systems, and, finally, characterize the statistical properties of chaotic attractors leading to possible hyperchaotic behavior.

Lower Back Pain Beyond Routine Causes: Sacral Spinal Epidural Arteriovenous Fistula (SEDAVF).

Lower back pain (LBP) is a frequent complaint, even among young people. The most common cause is attributed to slipped discs or vertebral fractures. Less common etiologies should also be considered when presenting with typical symptoms of severe backache.

On the higher-order smallest ring-star network of Chialvo neurons under diffusive couplings.

Network dynamical systems with higher-order interactions are a current trending topic, pervasive in many applied fields. However, our focus in this work is neurodynamics. We numerically study the dynamics of the smallest higher-order network of neurons arranged in a ring-star topology.

A Study Comparing Centchroman and Evening Primrose Oil in the Treatment of Benign Breast Disease.

Introduction: Females seeking medical attention at breast clinics commonly present with nonmalignant breast conditions, including nonspecific breast pain or distinct masses like fibroadenomas. Due to its variability, it may be difficult to quantify breast pain. The purpose of the research was to compare centchroman and evening primrose oil to identify a cost-effective, secure, and efficient treatment for benign breast disease.
