Irreversible ischemic injury occurs after coronary artery occlusion in vivo, first in the subendocardium and progressing toward the subepicardium over time. presumably due to transmural variations in collateral flow or wall tension. In this study, 10 left ventricular globally ischemic slabs were created that were free of wall tension and collateral flow. The onset and completion of ischemic con...

A mapping from the vertex set of a graph G = (V,E) into an interval of integers {0, . . . , k} is an L(2, 1)-labelling of G of span k if any two adjacent vertices are mapped onto integers that are at least 2 apart, and every two vertices with a common neighbour are mapped onto distinct integers. It is known that for any fixed k ≥ 4, deciding the existence of such a labelling is an NP-complete p...

Monagrillo (3520–1300 cal BC) is Panama’s oldest pottery. Archaeologists assumed it was a low-fired expedient ware made with any available clay. We studied 1) clay sources (thin sections; DTA; shrinkage, porosity, and plasticity tests), 2) manufacturing techniques (xeroradiography; thin sections; visual inspection), and 3) firing temperature (SEM-EDS; porosity tests). We identified two clay typ...

We conjecture a generalization of Dilworth’s theorem to direct products of partial orders. In particular, we conjecture that the largest “semiantichain” and the smallest “unichain covering” have the same size. We consider a special c lass of semiantichains and unichain coverings and determine when equality holds for them. This conjecture implies the existence of k-saturated partitions. A strong...

We introduce and survey results on two families of zeta functions connected to the multiplicative and additive theory of integer partitions. In the case of the multiplicative theory, we provide specialization formulas and results on the analytic continuations of these “partition zeta functions”, find unusual formulas for the Riemann zeta function, prove identities for multiple zeta values, and ...

" The theory of formal disciplinenthat is, the view that instruction in abstract rule systems can affect reasoning about everyday-life eventsnhas been rejected by 20th century psychologists on the basis of rather scant evidence. We examined the effects of graduate training in law, medicine, psychology, and chemistry on statistical reasoning, methodological reasoning about confounded variables, ...

Different regions, with different contexts and values, will follow sustainability transformation pathways, giving rise to tensions opportunities as the outcomes of regional pathways interact. To navigate these changes, we need a better understanding how interact produce for people nature. Creating sustainable just future require major shift in humans live in, with, Earth system one another.1Lea...

Most species of flowering plants rely on animal pollinators for effective mating (Ollerton et al., 2011), often interacting with diverse communities floral visitors 2007; Waser 1996). However, many commonly receive incompatible pollen, self-pollen or pollen from closely related individuals, thus influencing the quality that reaches target (Aizen & Harder, Ashman 2004). Such reductions in plant ...
