While Robust Model Predictive Control considers the worst-case system uncertainty, Stochastic Control, using chance constraints, provides less conservative solutions by allowing a certain constraint violation probability depending on predefined risk parameter. However, for safety-critical systems it is not only important to bound but reduce this as much possible. Therefore, an approach necessar...

background colorectal cancer (crc) is the second most common malignancy in the world.  however, its mortality rate can be reduced if diagnosed early. p33 ing1b is a tumor suppressor protein, which plays a role in growth control and apoptosis. suppression of p33 ing1b is associated with the loss of cellular growth control. however, p33 ing1b expression in crc and its correlations with clinicopat...

Treatment planning is a trial and error process that determines optimal dwell times, dose distribution, and loading pattern for high dose rate brachytherapy. Planning systems offer a number of dose calculation methods to either normalize or optimize the radiation dose. Each method has its own characteristics for achieving therapeutic dose to mitigate cancer growth without harming contiguous nor...

The BANG polymer gel dosimeter was used to evaluate 3D absorbed dose distributions in tissue delivered with Gamma Knife stereotactic radiosurgery systems. We compared dose distributions calculated with Leksell GammaPlan (LGP) treatment-planning software with dose distributions measured with the polymer gel dosimeter for single-shot irradiations. Head-sized spherical glass vessels filled with th...

conclusions radical nephrectomy and tumor thrombectomy by intrapericardial control without cardiopulmonary bypass and hypothermic circulatory arrest is a safe and effective procedure that can avoid serious intra- and postoperative complications while providing acceptable cancer-control and mortality results. case presentation the records of six patients with supradiaphragmatic tumor thrombi, wh...
