Background: Standard medical treatments for patent ductus arteriosus (PDA) closure are, including indomethacin/ibuprofen and surgical ligation. Nowadays, a new strategy to close PDA is the use of paracetamol. The present study aimed to describe the use of intravenous (IV) paracetamol for PDA closure in neonates who present a contraindication to ibuprofen or ibuprofen failure with no possibility...

Improving and maintaining data quality has become a critical issue for many companies and organizations because poor data degrades organizational performance whereas quality data results in cost saving and customer satisfaction. Activities such as identifying and removing ”duplicate” database records from a single database, and correlating records, which identify the same real world ”entity”, f...

The serial transitive closure problem is the problem of, given a directed graph G and a list of edges, called closure edges, which are in the transitive closure of the graph, to generate all the closure edges from edges in G . We give a nearly linear upper bound on the number of steps in optimal solutions to the serial transitive closure problem for the case of graphs which are trees. “Nearly l...

background: the transcatheter closure of patent ductus arteriosus has advanced rapidly with improvements in device designs. the aim of this study was to analyze the safety, efficacy, and early and intermediate follow-up results of the percutaneous closure of persistent ductus arteriosus (pda) with the amplatzer ductal occluder (ado) in children.   methods: between may 2004 and march 2007, fifty...

In this paper we prove that any distance-balanced graph $G$ with $Delta(G)geq |V(G)|-3$ is regular. Also we define notion of distance-balanced closure of a graph and we find distance-balanced closures of trees $T$ with $Delta(T)geq |V(T)|-3$.

In this paper, we introduce and study the concept of $r$-fuzzy regular semi open (closed) sets in smooth topological spaces. By using $r$-fuzzy regular semi open (closed) sets, we define a new fuzzy closure operator namely $r$-fuzzy regular semi interior (closure) operator. Also, we introduce fuzzy regular semi continuous and fuzzy regular semi irresolute mappings. Moreover, we investigate the ...

the present study attempts to investigate parsing preferences (early vs. late closure) of native and l2 learners of both english and persian when they read ambiguous relative clauses. the purpose is to find out if l2 learners process l2 linguistic input in the way monolingual speakers of that language do. the participants took tests including 10 test sentences plus 10 distractors, each followed...
