However, in this role, collapse is merely a black box for thermodynamically irreversible interaction with a classical environment. Calculations of quantum decoherence predict apparent wave function collapse when a superposition forms between the quantum system's states and the environment's states. Significantly, the combined wave function of the system and environment continue to obey the SchrÃ¶dinger equation.
Exercise can exacerbate the burning sensation in knee. Rheumatoid arthritis is an autoimmune condition where the body attacks its own tissues and causes joint inflammation. Knee bursitis occurs when there is an inflammation in the fluid-filled sac in the knee joint.
The most common causes of knee weakness are osteoarthritis, sprain or strain, and chronic knee pain. Other possible causes, such as injury to the knee, are more rare. Osteoarthritis 22. Sprain or strain 17. Chronic knee pain 15. Knee ligament or meniscus tear 8. Fracture of the leg 4. Bursitis 2.
