Purpose: An oversupply of qualified applicants leads to intense competition for the limited number of first year orthopedic residency positions. Therefore program directors can be more selective in choosing their future residents. However, it is unclear if there are resident characteristics that correspond with trainee performance. Methods: We asked 1. What resident characteristics are as...

Prof. Nosrat Safaeian from Sari, Australia received the Outstanding Achievement Award for Stewardship from the Iranian Society for Range Management at the 5th National Conference held in Boroujerd, Lorestan, Iran. He was born in Khorramabad and graduated in Ecology and Range Management from Montpellier, Science and Technique University, French in 1979.  I am honoured to introduce Prof. Nosrat S...

If σ is a permutation of n letters, say that j is an outstanding element (Fr. élément saillant) of σ if whenever i < j we have σ(i) < σ(j). A famous theorem of A. Rényi [R] (see also [C]) states that the number of permutations of n letters that have k outstanding elements is equal to the number that have k cycles, and therefore there are [ n k ] such permutations, the latter being the unsigned ...

Now that the global eradication of wild poliovirus is almost within sight, planning for the post-certification era is becoming a priority issue. It is agreed that a stockpile of appropriate polio vaccines will need to be established, and a surveillance and response capacity will need to be maintained, in order to protect the world against any possible future outbreaks attributable either to the...

length, introduction, background, purpose/goal, methods, results, discussion, and implications for practice. The use of tables and figures is also discussed.

Diamond is the first mineral type of presolar grains that were isolated from meteorites, yet it is one of the least understood presolar grain types. An isotopically anomalous component Xe-HL is carried by diamond and is characterized by excesses in both the light, p-process only isotopes (124 and 126) and the heavy, r-process only isotopes (134 and 136). These excesses are always correlated alt...

The Standard Model of particle physics agrees very well with experiment, but many important questions remain unanswered, among them are the following. What is the origin of particle masses and are they due to a Higgs boson? How does one understand the number of species of matter particles and how do they mix? What is the origin of the difference between matter and antimatter, and is it related ...

The first build of the chicken genome sequence appeared in March, 2004 - the first genome sequence of any animal agriculture species. That sequence was done primarily by whole genome shotgun Sanger sequencing, along with the use of an extensive BAC contig-based physical map to assemble the sequence contigs and scaffolds and align them to the known chicken chromosomes and linkage groups. Subsequ...

When a given process is seasonal and the seasonal pattern is stable the proportion of events that occur in a given fraction of the total period of the seasonality is constant over time. In this paper we present an application of Bayesian forecasting methods with stable seasonal patterns to insurance claims; specifically to claims incurred but not yet reported, IBNR. We assume that the time it t...
