BACKGROUND For many years, subcutaneous therapeutic port system was known as a major route to access central veins. However, significant complications have been reported through recent years. One of the most important complications of subcutaneous port implantation is skin necrosis. In order to decrease this complication, we would like to introduce subpectoral fascia port implantation through t...

The main objective of this work is to develop and evaluate the performance of a new PK technique, which can avert all types of port attacks and meets all network security requirements. The new technique utilizes three wellknown concepts, these are: port-knocking (PK), steganography, and mutual authentication, therefore, it is referred to as the hybrid port-knocking (HPK) technique. It can be us...

A two-port memory contains two duplicated sets of address decoders, which operate independently. Testing such memories requires the use of single-port tests as well as special two-port tests; the test strategy determines which tests have to be used. Many two-port memories have ports which are read-only or write-only; this impacts the possible tests for single-port and two-port memories, as well...

Single-incision laparoscopic cholecystectomy (SILC) has rapidly spread throughout the world because of its low invasiveness and because it is a scarless procedure. Various surgical methods of performing SILC are present in each institute; however, it is necessary to develop a standardized procedure that we can perform safely, such as the conventional 4-port laparoscopic cholecystectomy (LC). Th...

launched into the coupler at the input port 1 will partially emerge at port 3, from which it is guided along the fiber loop and reaches port 2 and will be partially coupled to the output port 4. The field at port 2 will couple partially to port 4 and partially to port 3, thus continuing to circulate in the loop. The characteristics of this all-fiber ring resonator have been investigated both th...

This paper proposes a re-conceptualization of the port supply chain as a smart service 10 system, according to the theory of the Service science. Starting from a short literature review about 11 the port supply chain approach and the Service science, a new comprehensive framework is 12 provided to better understand the seaport dynamics and the creation of competitive port supply 13 chains. The ...

A double forecasting model based on conditional expectation is proposed through probability distribution of port cargo throughput. A compound variable, being composed of the number of cargo ships arriving at the port and the operating efficiency of handling equipment, is constructed. The port cargo throughput is the sum of all compound variables which indicated the cargo throughput each time wh...

BACKGROUND AND OBJECTIVES Evidence is increasing that single-port or single-incision laparoscopic cholecystectomy is a safe and feasible alternative for cholecystectomy in children. In this study, we sought to compare the single-port hybrid technique, which we originally reported in 2012, with the conventional 4-port approach, in regards of complications, outcome, operative time and cost. MET...
