Fast Computation Of Graph Edit Distance

Measuring the similarity between two graphs is a basic operation with many applications. For example, in the fields of chemical informatics and drug design, we often need to compare the similarity of a chemical (as modeled by a labeled graph) to a known drug (as modeled by another labeled graph) in order to evaluate the

Is Progressivism Going Native In The United States?

Roughly 14 percent of the United States’ citizenry is comprised of individuals born outside of the United States who have immigrated to the U.S. A significant portion of the electorate, the opinion of the nation’s new citizens will likely shape policy priorities for decades to come. Therefore, it is worthwhile to study if and how

Hooray For Social Diversification

Multiunit systems rely on the capacity to socially interact. For example, multicellular organisms, such as ourselves, comprise differentiated tissues that are composed of tens of billions of cells, which all have the capacity to communicate and cooperatively interact with one another, sometimes leading to a strong division of labor and interdependence. Sometimes, mutant cells may

Strange Dracula Wasp With Large Mandibles in Fossil Amber From Myanmar From Ca. 99 Mio. Years Ago Shows Features of Different Wasp Families, Questioning Current Delimitation of Taxa

Once more, an unexpected fossil insect has been discovered in fossil amber from Myanmar — commonly called Burmese amber. The wasp, which now was described as Supraserphites draculi gen. sp. nov. (see Fig. 1), shows characteristics of two different families, Serphitidae and Archaeoserphitidae. Because of several characteristics common with Serphitidae, the new genus has been placed

Black Phosphorus: A Miracle Material For Future Biomedical Technology

Extensive and profound research in graphene has become a strong driver in the search for other 2 dimensional (2D) materials exhibiting a vast array of innovative properties including optical, electrical, sensing, biomedical, etc. (Yang et al., 2015). The family of 2D materials generally includes many chemical groups like 2D-transition metal dichalcogenides (TMDCs), transition metal dioxides

How Aging Affects Memories Of Personally Experienced Events

Our memory of personally experienced events is central to our identity and our sense of self. When remembering, we create an image of our experience in our minds. Previous research has shown that ­­­­­we judge our memories to be more accurate, vivid, and associated with a greater sense of re-experiencing events if these mental images

Watching Inside A Battery During The Charge/Discharge Cycle

Energy storage is one of the most important aspects of our highly demanding society. In the last decades, the search for appropriate energy storage materials has become of paramount importance to fulfill the increasing needs of electrical power. As such, energy storage has become a key research topic, and political authorities have created dedicated programs

Devonian World Revealed

Perhaps it is Facebook or perhaps it is our current political moment, but it seems more apparent than ever that we live in intellectual silos, partly inherited from our upbringing, but also actively maintained within our tribes. Science is not immune to this tendency, as is most apparent from the two tribes of America land-grant,

How Chemical Compounds Affect Fruit Bats’ Plant Interactions

Fruit bats are known to be able to discriminate, select, and track the essential oils of their preferred fruits. A few years ago, our research group hypothesized, experimented, and confirmed that these bats can be attracted with essential oils only – concentrated volatile aromas – of their preferred fruits both in forested and open areas.
