background : the population of mosquitoes is mainly influenced by the biotic and abiotic factors. although aedes aegypti was reported until 1960’s in the punjab, pakistan, the population has increased dramatically since 2009 and caused severe epidemics in 2011 due to heavy floods and rains. thus, this study was carried out to know the effect of biotic and abiotic factors on the population of ae...

Prosenjit Bose1, Pat Morin2, and Antoine Vigneron3 1 Carleton University. [email protected] 2 McGill University. [email protected] 3 Hong Kong University of Science and Technology. [email protected] Abstract. We consider the following problem. Given a polygon P , possibly with holes, and having n vertices, compute a pair of equal radius disks that do not intersect each other, are contained i...

Extremal black holes in M-theory compactification on M × S are microscopically represented by fivebranes wrapping P × S, where M is a Calabi-Yau threefold and P is a four-cycle in M . Additional spacetime charges arise from momentum around the S and expectation values for the self-dual three-form field strength in the fivebrane. The microscopic entropy of the fivebrane as a function of all the ...

We present a quadtree-based decomposition of the interior of a polygon with holes. The complete decomposition yields a constant factor approximation of the minimum weight Steiner triangulation (MWST) of the polygon. We show that this approximate MWST supports ray shooting queries in the query-sensitive sense as deened by Mitchell, Mount and Suri. A proper truncation of our quadtree-based decomp...

We obtain a very simple formula for the generating function of bipartite (resp. quasi-bipartite) planar maps with boundaries (holes) of prescribed lengths, which generalizes certain expressions obtained by Eynard in a book to appear. The formula is derived from a bijection due to Bouttier, Di Francesco and Guitter combined with a process (reminiscent of a construction of Pitman) of aggregating ...

When entrepreneurs enter “structural holes” in information networks, they can make a profit by exploiting the access and control benefits that these provide. That is Ronald Burt’s 13-year-old argument. Ever since, evidence for the suggested advantages from the occupancy of strategic network positions has steadily accumulated. What has not been shown, however, is whether those who strive for suc...

AIM To prospectively evaluate peripheral visual fields after vitrectomy for idiopathic macular holes. METHODS Goldmann perimetry was performed in 105 patients before, as well as 6 weeks and 12 months after macular hole surgery. RESULTS Only one patient (< 1%) with a stage III macular hole developed an asymptomatic postoperative visual field defect. The scotoma was wedge-shaped, peripherally...

Despite almost thirty years of research in the area of telework, the findings regarding outcomes remain equivocal (Bailey and Kurland, 2002). This research in progress hopes to advance understanding by identifying a key mechanism by which telework affects performance, specifically its influence on the social network properties of cohesion, power and structural holes. With knowledge of how the n...

Object-Oriented software structures represent multi-level characteristics. In this paper, two parameters -structural holes and closeness used in complex networks are introduced to study topological characteristics of software networks from multi-granularity perspective. By this method, software networks are observed and analyzed in three levels: package granularity, class granularity and method...
