In this paper, we consider the problem of linear equalization of polyphase channels and its blind implementation. These channels may result from oversampling the single output of a transmission channel or/and by receiving multiple outputs of an antenna array. A number of recent contributions in the field of blind channel identification have shown that polyphase channels can be blindly identifie...

Accurate modeling and design of protein-ligand interactions have broad applications in cell biology, synthetic biology and drug discovery but remain challenging without experimental protein structures. Here we developed an integrated protein-homology-modeling, ligand-docking protein-design approach that reconstructs protein-ligand binding sites from homolog protein structures in the presence of...

Non-volatile write cache (NVWC) can help to improve the performance of I/O-intensive tasks, especially writedominated tasks. The benefit of NVWC, however, cannot be fully exploited if an admission policy blindly caches all writes without differentiating the criticality of each write in terms of application performance. We propose a request-oriented admission policy, which caches only writes awa...

laryngeal mask is a supraglothic instrument for ventilation of patients who are under anesthesia. insertion of laryngeal mask requires maintaining sufficient depth of anesthesia to avoid airway reflex (gagging, coughing and spasms). the present study investigated two techniques of anesthesia with propofol-atracurium and thiopental-atracurium to facilitate insertion of the laryngeal mask, term o...

purpose: according to frequent needs to gastric decompression by nasogastric tube insertion during laparoscopic cholecystectomy, the current comparative study was accomplished through single blind clinical trial considering both the presence and the absence of guide wire insertion. materials and methods: twenty patients were selected for elective surgery of laparoscopic cholecystectomywith gene...

background & importance: acute epidural hematoma is a very rare complication of ventriculoperitoneal shunt insertion. the insertion of a ventriculoperitoneal shunt can cause sudden decompression of the brain, subsequent to which epidural hematoma occurs due to csf drainage. to our knowledge, there are only a few cases of acute epidural hematoma in the literature which required acute evacuation....

Introduction: A Nasogastric (NG) tube insertion is a common technique in all neonatal intensive care units (NICUs). In some cases, NG insertion in infants with friable esophageal tissues may lead to some adverse side-effects, although such problems are not commonly seen. Esophageal perforation is a rare but known complication associated with this procedure. Methods: An infant (first child), we...
