BACKGROUND AND STUDY AIMS  Endoscopic ultrasound-guided drainage of symptomatic walled-off pancreatic necrosis (WON) usually has been performed with double pigtail plastic stents (DPS) and more recently, with lumen-apposing metal stents (LAMS). However, LAMS are significantly more expensive and there are no comparative studies with DPS. Accordingly, we compared our experience with combined endo...

for more than three decades healthcare decentralization has been promoted in developing countries as a way of improving the financing and delivery of public healthcare. decision autonomy under healthcare decentralization would determine the role and scope of responsibility of local authorities. jalal mohammed, nicola north, and toni ashton analyze decision autonomy within decentralized services...

this study investigated the effect of applying the dynamic system theory (dst) and cognitive linguistics (cl) insights into grammar instruction on efl learners’ learning of english prepositions and learner autonomy. sixty iranian efl learners at the lower-intermediate level of language proficiency were randomly assigned to 1 experimental and 1 control group. the 2 groups filled out an autonomy ...

Investigating the “knowing”, a module of the KARDS model proposed by Kumaravadivelu (2012) for teacher education, of Iranian teachers of learner autonomy, this study is an attempt to illuminate some of the yet unexplored areas of teachers’ various types of knowledge of learner autonomy. Furthermore, it attempts to illustrate how Iranian Non-EFL teachers’ knowing affects their practices with reg...

We experimented a simple yet powerful optimization for Monte-Carlo Go tree search. It consists in dealing appropriately with strings that have two liberties. The heuristic is contained in one page of code and the Go program that uses it improves from 50 % of won games against Gnugo 3.6 to 76 % of won games.

The effect of an addition of 0.37 Wt % Won the overall transformation rate of the austenitepearlite reaction in a eutectoid steel is examined. Pearlite growth rates and interlamerllar spacing are measured as a function of transformation temperatures. Tungesten raises the Ael temperature, for most transformation temperatures, decreases the overall reaction rate, the growth rate and the interlame...
