A novel hyperchaotic system derived from asymmetric bidirectional coupling of two Lorenz oscillators: Synchronization analysis and cryptographic applications

This paper investigates a six-dimensional coupled Lorenz system obtained through bidirectional asymmetric diffusive coupling of two identical Lorenz oscillators. The proposed model is analyzed from both dynamical and synchronization perspectives. Dissipativity conditions, equilib...

Epidemiology and mortality predictors of acute poisoning in a Tunisian Emergency Department: a two-year retrospective study

Introduction Acute poisoning is a major public health challenge and a frequent cause of emergency department (ED) admission in Tunisia and North Africa. This study aimed to describe the epidemiological, clinical, and therapeutic characteristics of acute poisoning cases and to ide...

Gut Microbiota Signatures and Ecological Network Alterations Associated with Hemodialysis

Hemodialysis (HD) is the most widely used renal replacement therapy for patients with end-stage renal disease (ESRD) and is frequently accompanied by long-term complications that impair quality of life, including metabolic and inflammatory disturbances. Growing evidence suggests...

Native myocardial T1 reference values in a tunisian cohort using MOLLI and SMART1Map

Native T1 values in cardiac magnetic resonance (CMR) are influenced by acquisition sequence, physiological factors, and site-specific variability, complicating clinical interpretation. The absence of population-specific reference values further limits diagnostic accuracy. This st...

Pulmonary embolism secondary to renal tumor thrombus embolization: a challenging scenario

Pulmonary embolism (PE) may reveal an occult malignancy or complicate the course of an existing cancer. Renal cell carcinoma (RCC) is highly thrombogenic, especially in the presence of venous extension or tumor thrombus into the renal vein or inferior vena cava. However, PE as a...
