Previous research has shown that ideas which violate our expectations, such as schema-inconsistent concepts, enjoy privileged status in terms of memorability. In our study, memory for concepts that violate cultural (cultural schema-level) expectations (e.g., "illiterate teacher", "wooden bottle", or "thorny grass") versus domain-level (ontological) expectations (e.g., "speaking cat", "jumping m...

We prove this conjecture in case (a) and signi cantly extend the range of p and q for which it is known in case (b). In cases (a) and (b), these questions are equivalent to global stability of the xed point (L;L) of the planar map (u; v) = (v; f(u; v)). For as in case (a), we consider natural four dimensional extensions T of 3 and S of . For 0 q < p, we prove that (L;L; L; L) is a global stable...

Sugar maple syrup production is an important economic activity for eastern Canada and the northeastern United States. Since annual variations in syrup yield have been related to climate, there are concerns about the impacts of climatic change on the industry in the upcoming decades. Although the temporal variability of syrup yield has been studied for specific sites on different time scales or ...

Acer negundo (boxelder maple) is a North American native tree species that currently invades riparian and disturbed areas in Europe, affecting both bank stability and ecosystem biodiversity. As a response to managers’ requests, we aimed at finding an eco-friendly method which would locally remove this species and help habitat restoration. Four control methods were tested on A. negundo adults an...

At the Bear Brook Watershed in Maine (BBWM), the forest tree composition was characterized and the effects of the chronic ammonium sulfate ((NH(4))(2)SO(4)) treatment on basal area growth, foliar chemistry, and gas exchange were investigated on forest species. The BBWM is a paired watershed forest ecosystem study with one watershed, West Bear (WB), treated since 1989 with 26.6 kg N ha(-1) year(...

Thirty-one carbanilate derivatives were assayed for their capabilities to inhibit the ATPase activity of a plasma membrane fraction from Acer pseudoplatanus cells. At a concentration of 100 micromolar, nine compounds strongly inhibited the ATPase activity, with I(50) ranging from 14.5 micromolar to 35 micromolar. These molecules were also inhibitory to plasma membrane ATPases of other origins: ...

A study of 50 sugar maples {Acer saccharum) along Gates Mills Boulevard in Gates Mills, Ohio, showed that a tree's sap-sugar concentration tended to increase with decreasing tree health and increasing soil salt concentration. Relative tree health was determined by growth ring analysis. Salt concentration in soil was determined by measuring soil extract conductivity. Extract conductivity correla...

The dependence of vegetation attenuation on propagation geometry has been experimentally investigated at SHF band for isolated single trees. Two measurement heights (Trunk and Canopy) have been used in these experiments that involve three fully foliated trees, Common Whitebeam (Sorbus aria), Silver Maple (Acer Saccharinum) and Common Hazel (Corylus Avellana). Result shows that apart from freque...

In recent years, enterprises are facing the impact from the Financial Tsunami, factories moved outward, high production cost, shorter product life cycle, larger customization and global fierce competition. In order to survive, enterprises have to circulate all kind of information within the enterprise and supply chain to leverage the operation. This article presented five case studies including...

There is an error in the first sentence of the fourth paragraph in the Procedure section of the Methods. The data are available from Open Science Framework instead of Dataverse. The correct sentence is: The questionnaire programmed in Qualtrics was offered in Dutch and took on average 15 minutes to complete (on a notebook (Acer) or an iPad; the exact questionnaire in Dutch are available via htt...
