’Genormte Verträge’: Ein gangbarer Mittelweg in Verbindung mit internationalen Harmonisierungs-Bestrebungen und Gesetzesanpassungen sind 'genormte Verträge'. Benutzerseitig kann die Verwendung anerkannter, standardisierter Vertragsformen faktisch zu einem normativen Charakter derselben führen, womit gleichzeitig die Rechssprechung positiv beeinflusst wird. Als Beispiele gelten hier die Schweize...

This paper demonstrates that existing slice-based measures can reasonably be mapped to the field of state-based specification languages. By making use of Z specifications this contribution renews the idea of slice-profiles and derives coupling and cohesion measures for them. The measures are then assessed by taking a critical look at their sensitiveness in respect to modifications on the specif...

We constructed a product network based on the sales data collected and provided by a Fortune 500 Specialty Retailer. The structure of the network is dominated by small isolated components, dense cliquebased communities, and sparse stars and linear chains and pendants. We used the identified structural elements (tiles) to organize products into mini-categories—compact collections of potentially ...

Upon irradiation, cyclic imines containing o-amido groups are shown to produce reactive intermediates, amino azaxylylenes, which undergo intramolecular cycloadditions to tethered unsaturated pendants to yield complex N,O-heterocycles having an additional spiro-connected nitrogen heterocyclic moiety. Modular assembly of the photoprecursors allows expeditious increase of the complexity of the tar...

Two new polyoxetanes bearing dimesogenic pendants were prepared and their liquid crystalline properties were studied by differential scanning calorimetry (DSC), polarizing microscopy, and X-ray diffractometry. The dimesogens consist of cholesterol and biphenyl moieties connected through polymethylene spacers. Their biphenyl ends were attached to the oxetane monomer through a hexamethylene unit ...

Catalytic ultra-fast helix induction and its static helicity memory in a poly(biphenylylacetylene) were achieved by using chiral ammonium salts, as reported Katsuhiro Maeda, Eiji Yashima, co-workers their Research Article (e202217020). The remarkable acceleration of the helix-induction rate accompanied strong amplification relies on crown-ether-like specific intermolecular complex formation two...
