QUANTIFYING FAIRNESS IN QUEUING SYSTEMS: PRINCIPLES, APPROACHES, AND APPLICABILITY
In this article we discuss fairness in queues, view it in the context of social justice at large, and survey the recently published research work and publications dealing with the issue of measuring fairness of queues. The emphasis is placed on the underlying principles of the different measurement approaches, on reviewing their methodology, and on examining their applicability and intuitive appeal. Some quantitative results are also presented. The article has three major parts (sections) and a short concluding discussion. In the first part we discuss fairness in queues and its importance in the broader context of the prevailing conception of social justice at large, and the distinction between fairness of the queue and fairness at large is illuminated. The second part is dedicated to explaining and discussing three main properties expected of a fairness measure: conformity to the general concept of social justice, granularity, and intuitive appeal and rationality. The third part reviews the fairness of the queue evaluating and measuring approaches proposed and studied in recent years. We describe the underlying principles of the different approaches, present some of their results, and review them in context of the three main properties expected from a measure. The short discussion that follows centers on future research issue
Retrosternal Percutaneous Tracheostomy: An Approach for Predictably Impossible Classic Tracheostomy
Percutaneous tracheostomy is a routine procedure in intensive care
units. In cases of very low position of the larynx, cervical spine
deformation, morbid obesity, or neck tumor, performance of the
classic tracheostomy is inapplicable. Retrosternal approach to
tracheostomy in such 20 patients is herein reported. After
preoperative neck computerized tomography to define the neck
anatomy, a small suprasternal incision followed by a short
retrosternal tissue dissection to expose the trachea was done; the
trachea was then catheterized at the level of the 2nd ring in the
usual tracheostomy manner. The immediate and late (≥6 months) outcomes were similar to that of the standard tracheostomy. Thus,
percutaneous retrosternal tracheostomy is safe in patients with
abnormal positioning of the trachea or neck constitution. It is a
bedside applicable technique, that, however, requires caution to
avoid hazardous vascular complications

vices. Monotone Circuits for Matching Require Linear Depth
We prove that monotone circuits computing the perfect match-ing function on n-vertex graphs require Ω(n) depth. This implies an exponential gap between the depth of monotone and nonmonotone circuits
