Abstract Persistent homology is a recently popular multi-scale topological data analysis framework that has many potential scientific applications, particularly in neuroscience. The method can be effectively applied to yield patterns in nonlinear imaging data that are otherwise undetected by existing mono-scale techniques. Among several persistent homological features, recently proposed persist...

The number of business applications operated by enterprises to provide support for the business has increased over the last years. With increasing number of applications and connections between them, also the overall complexity of the application landscape has grown. A main task in managing an application landscape is maintaining quality levels. This article contributes a set of metrics for mea...

Abstract While a few species may thrive in urban areas, expansion is major driver of biodiversity loss. Columbids such as feral Rock Doves ( Columba livia domestica ) and Common Woodpigeon palumbus have adapted extremely well to the environment Europe beyond, but Stock Dove oenas ), bird farmland woodland edge UK national conservation concern, encountered infrequently areas. Here we explore mul...

Ecologists are challenged to construct models of the biological consequences of habitat loss and fragmentation. Here, we use a metapopulation model to predict the distribution of the Glanville fritillary butterfly during 22 years across a large heterogeneous landscape with 4,415 small dry meadows. The majority (74%) of the 125 networks into which the meadows were clustered are below the extinct...

Community colleges are an important part of the US higher education landscape, yet the aptitude and preparedness of student transfers to baccalaureate institutions is often called into question. Examining transcript records and demographic information of nearly 70,000 students across over 15 years of registrar records at a public university, this study performed a descriptive analysis of the pe...
