Priority setting is inevitable on the path towards universal health coverage. All countries experience a gap between their population's health needs and what is economically feasible for governments to provide. Can priority setting ever be fair and ethically acceptable? Fairness requires that unmet health needs be addressed, but in a fair order. Three criteria for priority setting are widely ac...

A priority queue transforms an input sequence ~r into an output sequence r which is a re-ordering of the sequence ~r. The set R of all such related pairs is studied in the case that tr is a binary sequence. It is proved that R is a partial order and that IRI = c,~+1, the (n + 1)th Catalan number, An efficient (O(n2)) algorithm is given for computing the number of outputs achievable from a given...

The increasingly attractive stereotactic body radiotherapy (SBRT) treatment for stage I lung cancer is concomitant with a large amount of monitor units (MU), leading to excessive out-of-field dose and prolonged beam-on time. The study aims to reduce the MU number and shorten the beam-on time by optimizing the planning parameters. Clinically acceptable treatment plans from fourteen patients suff...

We conducted a randomized experiment at the time of the 2004 flu vaccine shortage, providing information about the sharply reduced number of clinics and their schedule, and an appeal on cooperative restraint to a campus population. This strategy was intended to reduce demand for vaccination among non-priority individuals and to free available supplies for the priority population. It failed to a...

Quality of Service (QoS) is essential in Mobile Ad Hoc Networks (MANETs) in order to satisfy communication constraints, e.g. delay, as set in real-time applications. Traffic from such applications is normally treated as high-priority in contrast to non delay sensitive applications such as FTP or e-mail, which are largely delay tolerant and have their flows treated as low-priority in the network...

Priority resolver is ubiquitous in digital logic circuits as it is frequently used to optimize large number of inputs into a minimum number of outputs. This particular circuit exclusively demonstrate manifestation of outputs, controlled by the priority of logic interventions of the inputs. CMOS Logic made circuits with higher number of inputs experiences an excessive power dissipation. On the o...

Abstract Cofferdam work on dam construction has the potential for hazard risks in terms of occupational health and safety (OHS) such as extreme conditions weather natural disasters. This study aims to identify analyse these hazards using Hazard Identification Risk Assessment Control (HIRARC) Failure Mode Effect Analysis (FMEA) methods. The results showed that there were 16 including 12 identifi...

Recently, wireless body area networks (WBANs) have attracted significant consideration in ubiquitous healthcare. A number of medium access control (MAC) protocols, primarily derived from the superframe structure of the IEEE 802.15.4, have been proposed in literature. These MAC protocols aim to provide quality of service (QoS) by prioritizing different traffic types in WBANs. A contention access...
