There are more than 15,000 patients waiting for a liver transplant in the USA, with an average waiting time of 468 days and a mortality rate as high as 15-20%. Until artificial organs or xenotransplantation becomes a reality, living donor liver transplantation remains the best option for patients with end stage liver disease.

PURPOSE To assess the impact of pre-operative breast MRI on surgical waiting time, and to identify factors contributing to the delay. MATERIALS AND METHODS A retrospective cohort study involving 1274 patients was conducted after obtaining institutional ethics review. Surgical candidates for newly diagnosed breast cancer from 2007 to 2013 at a tertiary center were divided into 2 groups: those ...

This paper presents analytical models to find the mean waiting time for multiple access web service by using HTTP over SCTP. Mean waiting time is important measures of Quality of Service (QoS) in simultaneous users accessing a web server. The proposed mean waiting time model assumes the multiple packet losses and a narrowband network, which does not allow fast retransmission because of the smal...

Traditional B2C Electronic Commerce architecture instigated using n-Tier Client/Server architecture has continually been sluggish, intricate, and costly. With the advent of Cloud computing environment, the amenities vital for the Electronic Commerce architecture are accomplished by proficient organization, which comprises servers, storage supervision, network skills, and virtualization technolo...

Cloud Computing is a revolutionary way of providing shared resources over the Internet. Through the use of low level virtualization software, the Cloud provides virtualized computing hardware infrastructure in a manner similar to the public utilities, thus it is also termed as Infrastructure-as-a-Service or Utility Computing. Job scheduling algorithms is one of the most challenging theoretical ...

BACKGROUND The present study had two research questions. First, what is the average waiting time between diagnosis and treatment for Alberta women with breast cancer relative to Canadian Society for Surgical Oncology (CSSO) recommendations? Second, does patient age, cancer stage, patient community size, and year of diagnosis have a significant relationship to waiting time? METHODS The sample ...

in this paper we introduced a new priority rule algorithm in human queues. the suggested method is applicable in human lines with different demands (serving times) for different customers. in this method, the waiting time for each customer is related to the volume of demand. a common example of such a system is a bakery line. the usual priority rule algorithm in this kind of queue is first-in-f...

In this paper, a novel context aware medium access control scheme is proposed for multichannel buffer-aided cognitive networks. The proposed scheme allows management of the delay more efficiently by exploiting the packets’ context. In the proposed multiple access policy, two different context aware approaches for packet prioritization are presented. In the first method, more delay sensitive pac...

BACKGROUND The projected demand for total knee arthroplasty is staggering. At its root, the solution involves increasing supply or decreasing demand. Other developed nations have used rationing and wait times to distribute this service. However, economic impact and cost-effectiveness of waiting for TKA is unknown. METHODS A Markov decision model was constructed for a cost-utility analysis of ...

OBJECTIVE To assess the results achieved with a rapid referral pathway for suspected colorectal cancer (CRC), comparing with the standard referral pathway. METHODS Three-year audit of patients suspected of having CRC routed via a rapid referral pathway, and patients with CRC routed via the standard referral pathway of a health care district serving a population of 498,000 in Madrid (Spain). O...
