Currently there is not a satisfactory relativistic spontaneous collapse model. Here we show the impossibility of simple generalization continuous (CSL) model to framework. We consider mass coupled as in non-relativistic limit this gives CSL that Lorentz covariant equation cannot simultaneously satisfy following conditions: i) To avoid divergent rate energy, ii) prevent superluminal signaling.

Background The use of a medical simulator should enhance the goals of minimally invasive surgery: patient safety, cosmesis, shortening the length of hospital admissions, and reducing cost. Using an innovative approach to the handling of ultrasound images in virtual reality simulation, this article describes a process that employs a hybrid model of deformable models that can be applied in the te...
