COVER PICTURE Mandy Hecht, Tobias Fischer, Paul Dietrich, Werner Kraus, Ana B. Descalzo, Wolfgang E. S. Unger, and Knut Rurack* Retrieving quantitative molecular information from macroscopic areas in a reliable manner at micrometric resolution is a challenging task, yet essential for a better understanding and control of the assembly of (bio)chemical entities on a functional surface. In their F...
Paliurus favonii Unger is recognized and described based on fruits from the Oligocene Ningming flora of Guangxi, South China. Characteristics of the present specimens include circular winged fruits that are 10.0-11.5 mm in diameter with a central endocarp at 3.0 to 4.0 mm in diameter. The specimens fall into the morphological range of the fossil species P. favonii, which has been observed in ot...

We present algorithms for the two layer straightline crossing minimization problem that are able to compute exact optima. Our computational results lead us to the conclusion that there is no need for heuristics if one layer is xed, even though the problem is NP-hard, and that for the general problem with two variable layers, true optima can be computed for sparse instances in which the smaller ...

Markups, which are when prices greater than the marginal cost of production, have increased in USA over last decades. Our paper explores differences markups between Information Technology (IT) and non-IT firms. By doing so, we contribute to understanding role IT industry increase markups. We extend De Loecker, Eeckhout, Unger (Citation2020), who find that publicly traded firms risen since 1980....
abstract the traditional or liberal theory of contract always had encounter serious critics. the authors of this article have criticized this theory- based on new theory of unger (a pioneer in the critical legal studies movement) - and also have analyzed the strengths and weaknesses of that. this theory consists of a principle and a counter principle that include freedom of contract against the...
Unger, Leon (University of Illinois, Urbana), and R. D. DeMoss. Metabolism of a proline analogue, l-thiazolidine-4-carboxylic acid, by Escherichia coli. J. Bacteriol. 91:1564-1569. 1966.-Resting cells of Escherichia coli K-12, pregrown in a proline- and thioproline-free medium, oxidize the proline analogue, l-thiazolidine-4-carboxylic acid (l-thioproline), without a lag with the consumption of ...
