Aggregating Causal Runs into Workflow Nets

This paper provides three algorithms for constructing system nets from sets of partially-ordered causal runs. The three aggregation algorithms differ with respect to the assumptions about the information contained in the causal runs. Specifically, we look at the situations where labels of conditions (i.e. references to places) or events (i.e. references to transitions) are unknown. Since the pa...

An Experimental Investigation into the Arching Effect in Fine Sand

In the current paper results of a well instrumented experimental procedure for studying the arching effect in loose and dense sand are presented. The apparatus comprises concentric circular trapdoors with different diameters that can yield downward while stresses and deformations are recorded simultaneously. As the trapdoor starts to yield, the whole soil mass deforms elastically. However, afte...

A piggyBac route to transgenic honeybees.

The honeybee Apis mellifera is one of the most recognized and revered insect species throughout human history. The economic impact of the honeybee as an essential pollinator of key crops is estimated to be in the range of billions of dollars per year. The honeybee also serves as a powerful animal model for studies of the evolution and regulation of social behaviors at the endocrine, cellular, g...
