Pressure and temperature diagram of C60 from atomistic simulations.

Although widely studied experimentally in the 1990s, the structure and properties of low-dimensional or high-pressure phases of fullerenes have recently been re-examined. Remarkably, recent experiments have shown that transparent, nearly pure amorphous sp3-bonded carbon phases can be obtained by heating a C60 molecular crystal at a high pressure. With the additional aim of testing the ability of three classical carbon potentials reactive empirical bond order, environment-dependent interatomic potential, and reactive force-field to reproduce these results, we investigate the details of the structural transformations undergone by fullerene crystals over a wide range of pressures and temperatures.

Blockchain and IoT integration for secure short-term and long-term air quality monitoring system using optimized neural network.

Accurate air pollution prediction is vital for residents' well-being. This research introduces a secure air quality monitoring system using neural networks and blockchain for robust analysis, precise predictions, and early pollution detection. Blockchain guarantees data integrity, security, and transparency.

The yield of 24-hour ambulatory electrocardiography in the assessment of symptomatic school-age children.

Introduction: Lightheadedness, syncope, dyspnea, chest pain, palpitation, loss of consciousness (LOC) or malaise are a frequent reason for consultation in school-age children (SAC). The yield of holter monitoring (HM) in the investigation of these symptoms in SAC is still controversial given the scarce studies.

Aim: To determine the prevalence of baseline ECG abnormalities and those detected in HM in SAC, and to assess the predictive factors of abnormal HM test.

Double-Chambered Left Ventricle Diagnosed in Fetus and Follow-up During the First Year of Life: A Case Report.

Double-chambered left ventricle (DCLV) is a rare congenital cardiac lesion. It is usually an incidental finding in children and young adults. Diagnosis during fetal life is exceedingly rare.

Paucisymptomatic Tetralogy of Fallot diagnosed in a 56-year-old patient: a case report.

Background: Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease. It is generally diagnosed and surgically repaired early in life, with good overall outcomes.

Case Presentation: We report the case of a patient incidentally diagnosed with paucisymptomatic TOF at the age of 56 years old, during investigations for carbon monoxide poisoning.
