Right of rescission of the author gem. 137 1 Abs. 1 UrhG in practice
No full textAs part of the reform of the German Copyright Act (UrhG) Section 1371 deals with a transitional measure for new types of publication. In particular it allows publishers to make use of online publishing without previous license agreements with copyright holders. However, a copyright holder can prohibit such forms of publication through a formal declaration within one year of the law's enactment. This paper deals with the right to revoke permission and discusses several specific instances in order to show whether, and to what extent, the exercise of this legal right actually safeguards the interests of copyright holders

Widely applicable background depletion step enables transaminase evolution through solid-phase screening
No full textDirected evolution of transaminases is a widespread technique in the development of highly sought-after biocatalysts for industrial applications. This process, however, is challenged by the limited availability of effective high-throughput protocols to evaluate mutant libraries. Here we report a rapid, reliable, and widely applicable background depletion method for solid-phase screening of transaminase variants, which was successfully applied to a transaminase from Halomonas elongata (HEWT), evolved through rounds of random mutagenesis towards a series of diverse prochiral ketones. This approach enabled the identification of transaminase variants in viable cells with significantly improved activity towards parasubstituted acetophenones (up to 60-fold), as well as tetrahydrothiophen-3-one and related substrates. Rationalisation of the mutants was assisted by determination of the high-resolution wild-type HEWT crystal structure presented herein
Why the Approach of Heckmann v. Ahmanson Will Not Become the Prevailing Greenmail Viewpoint: Race to the Bottom Continues
No full textFirstly, this article will introduce greenmail. It will then discuss the applicability of both federal and state law to payment of greenmail by target companies, examining prominent cases where appropriate. Finally, it will explain why the Heckmann court's opinion will not become the majority viewpoint. Although the California appellate court in Heckmann reached a just and fair decision, race to the bottom principles will prevent the position taken by the California court from becoming the wave of the future
On the Relationship between Filter Spaces and Equilogical Spaces
No full textIt was already known that the category of T 0 topological spaces is not itself cartesian closed, but can be embedded into the cartesian closed categories FIL of filter spaces and EQU of equilogical spaces where the latter embeds into the cartesian closed category ASSM of assemblies over algebraic lattices. Here, we first clarify the notion of filter space---there are at least three versions FIL a ' FIL b ' FIL c in the literature. We establish adjunctions between FIL a and ASSM and between FIL c and ASSM, and show that FIL b and FIL c are equivalent to reflective full subcategories of ASSM. The corresponding categories FIL b 0 and FIL c 0 of T 0 spaces are equivalent to full subcategories of EQU.
