In this paper we demonstrate the application of time-varying graphs (TVGs) for modeling and analyzing multi-robot foremost coverage in dynamic environments. In particular, we consider the multi-robot, multi-depot Dynamic Map Visitation Problem (DMVP), in which a team of robots must visit a collection of critical locations as quickly as possible, in an environment that may change rapidly and unp...

There is an ever-increasing interest in investigating dynamics in timevarying graphs (TVGs). Nevertheless, so far, the notion of centrality in TVG scenarios usually refers to metrics that assess the relative importance of nodes along the temporal evolution of the dynamic complex network. For some TVG scenarios, however, more important than identifying the central nodes under a given node centra...

While developed for managing individuals with atrial fibrillation, risk stratification schemes for stroke, such as CHADS2, may be useful in population-based studies, including those assessing process of care. We investigated how certain decisions in identifying diagnoses from administrative data affect the apparent prevalence of CHADS2-associated diagnoses and distribution of scores. Two sets o...

Cross-linguistic studies allow for analyses that would be impossible in a single language. To better understand the factors that underlie sentence production, we investigated production choices in main and relative clause production tasks in three languages: English, Japanese and Korean. The effects of both non-linguistic attributes (such as conceptual animacy) and language specific properties ...

Recent issues of ARE Update featured articles evaluating the failures of two California marketing cooperatives, Tri Valley Growers (TVG) and Rice Growers Association (RGA). Along with Blue Anchor’s dissolution and Calavo’s conversion, these combined events have created doubts about the future of cooperatives in California agriculture. Restructured forms of cooperatives are emerging. For example...
