We consider the dynamics of continuously measured many-body chaotic quantum systems. Focusing on observable state purification, we analytically describe limits strong and weak measurement rate, where in latter case monitoring up to time scales exponentially long numbers particles is required. complement analysis limiting regimes with construction an effective replica theory providing informatio...

abstract the purpose of this article is to present a system dynamics (sd) model for studying the ‎interconnections among human being weight, eating habit, exercise, body fat, take-in medication, drugs-uses, and the health problems in general. due to the fact that all of these factors have direct and indirect impacts on the expenses that insurance company have to pay this author is proposing a s...
