Advanced rectal tumors can be treated with curative intent by surgical resection of the rectum including other pelvic organs. The reconstruction of the urinary and gastrointestinal tracts depends on the distance between the tumor and the anus, the patient’s status and the experience of the surgical team. This is a case of a male patient with a locally(More)
The current demand for more complex models has initiated a shift away from statespace models towards models described by both dynamic and algebraic equations, so-called implicit systems. These models arise as the natural product of real processes. In this paper, we consider design of observers for a class of implicit systems. The proposed observer combines(More)
Newest processes of CMOS manufacturing allow integrating billions of transistors in a single chip. This huge integration enables to perform complex circuits, which require an energy efficient communication architecture with high scalability and parallelism degree, such as a Network-on-Chip (NoC). However, these technologies are very close to physical(More)
Newest technologies of integrated circuits fabrication allow billions of transistors arranged in a single chip enabling to implement a complex parallel system, which requires a high scalable and parallel communication architecture, such as a Network-on-Chip (NoC). These technologies are very close to physical limitations increasing faults in manufacture and(More)
Suspension laryngoscopy is one of the most common otolaryngological procedures for the diagnosis and surgical approach to the larynx. However, most thoracic surgeons are not familiar with the procedure and seldom use it. The indications for its use are similar to those for that of rigid bronchoscopy (dilatation, endoprosthesis insertion, and tumor(More)
The increasing number of available antiretroviral drugs (ARV) for treating HIV-1 infection has promoted an amazing reduction on AIDS-associated morbidity and mortality. However, adverse events are still a frequent finding in on-treatment patients, and may have a negative impact on patient’s quality of life, adherence to therapy, and long term health(More)
We report the case of a 33-year-old white female patient. Her personal history was unremarkable. She presented with a three-month history of progressive dysphagia, which was accompanied by vomiting after eating, weight loss (8 kg), and asthenia. Physical examination was normal. Laboratory test results showed microcytic hypochromic anemia (hemoglobin, 10.2(More)
