We report high resolution simultaneous measurements of electrical conductance and force gradient between two sharp gold tips as their separation is varied from the tunneling distance to atomic-size contact. The use of atomically sharp tips minimizes van der Waals interaction, making it possible to identify the short-range metallic adhesion contribution to the total force.

The monotypic genus Linoderus Sharp, 1885 was described based on a species from Panama and since the original description nearly nothing has been added to its taxonomical knowledge. The aim of the present paper is to describe a new species of the genus from Colombia and to report the genus for the first time from South America, adding some biological notes of the species.

In the present article we give geometric generalizations of the estimates from Chapters 5,6,7 from [4], while extending their sharpness to new cases.

What does it take to experience grace? I argue that for followers of the Chinese Christian reformers Watchman Nee and Witness Lee, in China, Taiwan, United States, grace is experienced as an intended gift with a missing motivating intention. For group which God’s intentions are rigorously mapped out, experiencing thus no simple feat. In particular, show how occurs moments apparent wrongdoing wh...
