Retrocecal Appendicitis Post-blunt Abdominal Trauma: A Case Report.

Appendicitis, characterized by inflammation and obstruction of the appendiceal lumen, is a common surgical emergency often attributed to various factors. We present the case of an 18-year-old female who developed retrocecal appendicitis following blunt abdominal trauma, a rare occurrence with significant diagnostic challenges. Initial symptoms mimicked upper abdominal trauma, evolving to classic signs of appendicitis within hours.

Quantum work fluctuations in connection with the Jarzynski equality.

A result of great theoretical and experimental interest, the Jarzynski equality predicts a free energy change ΔF of a system at inverse temperature β from an ensemble average of nonequilibrium exponential work, i.e., 〈e^{-βW}〉=e^{-βΔF}.
