We show that all finite dimensional pointed Hopf algebras with the same diagram in the classification scheme of Andruskiewitsch and Schneider are cocycle deformations of each other. This is done by giving first a suitable characterization of such Hopf algebras, which allows for the application of a result of Masuoka about Morita-Takeuchi equivalence and of Schauenburg about Hopf Galois extensio...

This paper reviews the literature on unplanned purchasing and impulse purchasing in particular. Various definitions and explanations of the phenomena are examined. Because impulse purchasing may often be deemed socially undesirable, it is argued that a qualitative research approach is particularly appropriate in order to gain maximum insight. A study employing enabling techniques (including sel...

This paper describes the design of an integrity-aware Forensic Evidence Management System (FEMS). The well-known Biba integrity model is employed to preserve and reason about the integrity of stored evidence. Casey’s certainty scale provides the integrity classification scheme needed to apply the Biba model. The paper also discusses the benefits of using an integrity-aware system for managing d...

Different stationarity and regularity concepts for extended real-valued functions on metric spaces are considered in the paper. The properties are characterized in terms of certain local constants. A classification scheme for stationarity/regularity constants and corresponding concepts is proposed. The relations between different constants are established.

Digitalisation can be viewed as the motor of transformation for the tourism industry in the age of the internet economy. While the increase of digitalised or completely virtualised products in tourism reflects this development, current eTourism applications are rather fragmented with regards to conceptualisation, structure and layout. However, in the increasing competitive internet economy, a s...

To investigate effects of visual experience versus preprogrammed mechanisms on visual development, we used multiple regression analysis to determine the extent to which a variety of variables (that differ in the extent to which they are tied to visual experience) predict luminance and chromatic (red/green) contrast sensitivity (CS), which are mediated by the magnocellular (M) and parvocellular ...

The Hölder setting of the metric subregularity property of set-valued mappings between general metric or Banach/Asplund spaces is investigated in the framework of the theory of error bounds for extended real-valued functions of two variables. A classification scheme for the general Hölder metric subregularity criteria is presented. The criteria are formulated in terms of several kinds of primal...

We report a simple strategy to construct a multiple gadolinium complex decorated fullerene (CGDn) as an enhanced T1 contrast agent. The CGDn exhibits much higher T1 relaxivity (∼49.7 mM(-1) s(-1)) than individual Gd-DOTA, and shows excellent T1 contrast enhancement ability both in vitro and in vivo.

3D gesture based systems are becoming ubiquitous and there are many mid-air hand gestures that exist for interacting with digital surfaces and displays. There is no well defined gesture set for 3D mid-air hand gestures which makes it difficult to develop applications that have consistent gestures. To understand what gestures exist we conducted the first comprehensive systematic literature revie...

The classifiers characterized by a tagged feature-class repre­ sentation, a univariate discrimination approach, a cooperative classification scheme, and a logic-based learning strategy are discussed. Neither of the classifiers bears the constraints to the fixed sets of features and classes. Concepts of the tagged feature-class representation and the properties of feature matching in the dynamic...
