Properly selected port sites for robot-assisted coronary artery bypass graft (CABG) improve the efficiency and quality of these procedures. In clinical practice, surgeons select port locations using external anatomic landmarks to estimate a patient's internal anatomy. This paper proposes an automated approach to port selection based on a preoperative image of the patient, thus avoiding the need...

BACKGROUND AND OBJECTIVE A recent FDA safety communication has discouraged the use of a power morcellator for myoma extraction and has called for a change in surgical techniques for myomectomy. The objective of this study was to compare surgical outcomes of laparoscopic single-, two-, and conventional three-port myomectomy and to evaluate the feasibility of contained manual morcellation for ute...

Background: Since the advent of four-port laparoscopic cholecystectomy (LC), many modifications have been made that aimed to improve cosmesis and patient prognosis. Here we compared a variety of surgical outcomes such as quality of life three months after surgery between three-port LC and conventional four-port LC. Methods: This study presents an analysis of 245 patients with cholelithiasis who...

In a multiprocessor network, sending a packet typically refers to start-up time and transmission time. To optimize these two times, as opposed to earlier solutions, a spanning tree and multiple spanning trees are constructed to solve four types of broadcasting problems in an (n, k)-star graph: one-to-all or all-to-all broadcasting with either one-port or all-port communication model, respective...

Concerning the information asymmetry, subjectivity and other problems in the prediction of port customer credit risk level, a port customer credit risk evaluation system was designed, which provided the quantification base for port customer credit risk prediction. External-internal information fusion model was proposed for port customer credit risk prediction. Customers’ internal history inform...

abstract background peripheral blood vessels, due to availability are used for many years in cancer patients, however in patients with potentially harmful drugs to skin (vesicant drugs) or difficult accessibility to vessels, the use of implantable port (totally implantable venous access port-tivap)devices with central vascular access are important.  materials and methods in this retrospective s...

When the service region of ports overlap, consignors’ selecting behaviors for shipping ports become homogeneous to commuters’ choosing behaviors on trips. The commuters’ travel behaviors can be described through a probabilistic model in transportation planning. In this study, we adopt the transportation probabilistic forecast model to forecast port throughput. First, we amend the model with a p...

Scanning of ports on a computer occurs frequently on the Internet. An attacker performs port scans of IP addresses to find vulnerable hosts to compromise. However, it is also useful for system administrators and other network defenders to detect port scans as possible preliminaries to more serious attacks. It is a very difficult task to recognize instances of malicious port scanning. In general...

Extraction of coupling of modes (COM) parameters from the manufacturing process of a surface acoustic wave device (SAW) is important in practice. In this study, we employed an inverse algorithm to recover the COM parameters from the measured admittance of a one-port SAW resonator. For completeness, the COM equations, the P-matrix representation and the related COM parameters have been summarize...

BACKGROUND Radical cystectomy (RC) with or without neoadjuvant chemotherapy is the standard treatment for muscle-invasive bladder cancers. However, the locoregional recurrence rate is still significantly higher for locally advanced cases post-RC. The underuse of postoperative radiotherapy (PORT) in such cases after RC is related mainly to a lack of proven survival benefit. Here we are reporting...
