International Endodontic Journal, EarlyView.Abstract Aim This study aimed to investigate the effects of açai on bone and systemic damage caused by apical periodontitis (AP) in an animal model. Methodology In this experimental study, 32 male Wistar rats were randomly allocated into six groups—Control 14 days (n = 4), Control 28 days (n = 4), AP 14 days (n = 4), AP 28 days (n = 4), AP plus açai ...

QUANTUM WORMHOLE AS A RICCI FLOW [PDF]
International Journal of Geometric Methods in Modern Physics, 2009 The idea is considered that a quantum wormhole in a spacetime foam can be described as a Ricci flow. In this interpretation, the Ricci flow is a statistical system and every metric in the Ricci flow is a microscopical state. The probability density of the microscopical state is connected with a Perelman's functional of a rescaled Ricci flow.

Computer-Aided Civil and Infrastructure Engineering, EarlyView.Abstract The rise of exascale supercomputing has motivated an increase in high‐fidelity computational fluid dynamics (CFD) simulations. The detail in these simulations, often involving shape‐dependent, time‐variant flow domains and low‐speed, complex, turbulent flows, is essential for fueling innovations in fields like wind, civil, automotive, or ...

Psychological and Clinical Factors Mediate Post‐COVID‐19 Irritable Bowel Syndrome
Neurogastroenterology &Motility, EarlyView.ABSTRACT Background Exposure to COVID‐19 has been shown previously to be associated with a higher risk for irritable bowel syndrome (IBS). This study aimed to better explain this relationship using mediation analysis. Methods This post hoc analysis of a multicenter cohort study includes 623 patients with and without COVID‐19 infection.

Fractional nonholonomic Ricci flows [PDF]
Chaos, Solitons & Fractals, 2012 We formulate the fractional Ricci flow theory for (pseudo) Riemannian geometries enabled with nonholonomic distributions defining fractional integro-differential structures, for non-integer dimensions. There are constructed fractional analogs of Perelman's functionals and derived the corresponding fractional evolution (Hamilton's) equations.
