bronchogenic cyst is a result of abnormal development   of the ventral foregut presents as a discrete mass. most commonly, it is appeared in the middle mediastinum and rarely is seen in adults. we report a 35-year-old woman who was asymptomatic and incidentally was found with a mass in chest radiograph.

intraosseous movement of an unerupted tooth across the midline of the jaw is known as dental transmigration. this infrequent event is mostly found in the mandibular canines. there are four new cases of mandibular canine transmigration presented here. the literature on this anomalous phenomenon is also reviewed.

the purpose of this research is to analyze differential adpositional case marking (dacm) in vafsi within ot framework by using the generalization of aissen’s (2003) differential object marking (dom) model. while bossong (1985) has traced dom in more than 300 languages, dacm has not been investigated typologically, yet. dacm, as a branch of differential case marking (dcm), questions the effect o...

conclusions although treatment of ec in the present study had considerable success in the short-term follow-up, it should be noted, due to the unknown of the exact cause, no specific treatment or protocol has still been identified. introduction exfoliative cheilitis (ec) is a rare chronic inflammatory condition affecting the vermillion border of the lips and characterized by excessive productio...

The original Leapfrogging Samplesort operates on a sorted sample of size s and an unsorted part of size s+1. We generalize this to a sorted sample of size s and an unsorted part of size (2 − 1)(s+1), where k = O(1). We present a practical implementation of this class of algorithms and we show that the worst-case complexity is O(n log n) and the average-case complexity is O(n log n).
