Two plant genome size databases have been recently updated and/or extended: the Plant DNA C-values database (http://data.kew.org/cvalues), and GSAD, the Genome Size in Asteraceae database (http://www.asteraceaegenomesize.com). While the first provides information on nuclear DNA contents across land plants and some algal groups, the second is focused on one of the largest and most economically i...
The majority of people show persistent poor performance in reasoning about "stock-flow problems" in the laboratory. An important example is the failure to understand the relationship between the "stock" of CO2 in the atmosphere, the "inflow" via anthropogenic CO2 emissions, and the "outflow" via natural CO2 absorption. This study addresses potential causes of reasoning failures in the CO2 accum...
The stock and flow management (SFM) problem is of high relevance for a broad range of decision makers in society, business, and personal affairs. Although in some areas highly sophisticated models and control concepts have been developed, the phenomena of excess stock and shortages are omnipresent. One recent explanation for these observations is offered by a stream of research, which finds evi...
Cell-DEVS formalism extends cellular automata modeling. In this paper, we present a simple model for landslides using a model of a sand pile. The model uses Cell-DEVS formalism and CD++ tool to model and simulate landslides. Using this simple model, we present how Cell-DEVS formalism can be used to model systems that involve material accumulation and flow. Material flow and accumulation need sp...
Background As for other pathologies, the pathogenesis of venous thrombo-embolism (VTE) is multifactorial. A comprehensive understanding of the pathogenesis of venous thrombosis is essential for identifying patients at increased risk as in elderly patients with congestive heart failure (CHD) and with presence of chronic venous insufficiency (IVC). Eberhard Mammen postulated immobility as the lea...
After many years of research, small diameter, synthetic vascular grafts still lack the necessary biologic integration to perform ideally in clinical settings. Endothelialization of vascular grafts has the potential to improve synthetic graft function, and endothelial outgrowth cells (EOCs) are a promising autologous cell source. Yet no work has established the link between endothelial cell func...
