We define p-adic multiple zeta and log gamma functions using multiple Volkenborn integrals, and develop some of their properties. Although our functions are close analogues of classical Barnes multiple zeta and log gamma functions and have many properties similar to them, we find that our p-adic analogues also satisfy reflection functional equations which have no analogues to the complex case. ...

A class of structures is said to have the homomorphism-preservation property just in case every firstorder formula that is preserved by homomorphisms on this class is equivalent to an existential-positive formula. It is known by a result of Rossman that the class of finite structures has this property and by previous work of Atserias et al. that various of its subclasses do. We extend the latte...

In our TREC participation, we used an ensemble approach in query expansion. Query expansion, such as synonym expansion, had shown promising results in medical literature search. On the other hand, some of the 2011 papers reported worse results from expansion. Since there are multiple knowledge sources available and each resource has clear strengths and weaknesses, we tested the combination of t...

The research reported in this paper has both a scientific and a commercial aim. The scientific interest is to explore the use of contexts in order to improve the quality of information brokering. In this paper it is shown that contexts in information brokering can be exploited to enable four directions of query reformulation: up and down (standard query expansion) and sideway reformulations of ...

Introduction: This study aimed to evaluate the effects of four-time inflation of the stent balloon at nominal pressure on optimal stent expansion in resistant lesions. Materials and Methods: This interventional study was conducted on 39 patients with coronary artery lesions, in whom Zotarolimus-eluting stents (N=20), Paclitaxel-eluting stents (N=11) and other stents (N=8) were deployed four tim...
