We consider collective quantification in natural language. For many years the common strategy in formalizing collective quantification has been to define the meanings of collective determiners, quantifying over collections, using certain typeshifting operations. These type-shifting operations, i.e., lifts, define the collective interpretations of determiners systematically from the standard mea...

This paper introduces a general matroid-theoretic construction which includes, as special cases, elementary lifts of matroids and bias matroids of biased graphs. To perform the construction on a matroid A/ , it is necessary (but not sufficient) to have a submodular function inducing M . Elementary lifts are obtained when the submodular function chosen is the rank function of M . We define what ...

Methane emissions from liquid unloadings were measured at 107 wells in natural gas production regions throughout the United States. Liquid unloadings clear wells of accumulated liquids to increase production, employing a variety of liquid lifting mechanisms. In this work, wells with and without plunger lifts were sampled. Most wells without plunger lifts unload less than 10 times per year with ...

Ropeless lifts are needed for vertical transport in the future super skyscrapers whose height is more than 800m because of the limited handling capacity of roped lifts for such buildings. The ropeless lifts have two advantages: multiple car operation in a single shaft and transferability between shafts. The ropeless lifts can be operated like double-track railway systems by making use of these ...

• The theta correspondence 1 is a correspondence between automorphic forms on two members of a dual reductive pair. Because of the relation between automorphic forms and automor-phic representations, it is also a correspondence between automorphic representations. The Siegel-Weil formula says that certain natural linear combinations of theta lifts are Siegel-type holomorphic Eisenstein Series.

When one lifts two objects of equal weight and appearance but different size, the smaller object usually feels heavier. New results show that this size-weight illusion can be inverted after extensive training with objects in which the natural size-weight relationship is artificially reversed.
