Subset-lex: did we miss an order?

We generalize a well-known algorithm for the generation of all subsets of a set in lexicographic order with respect to the sets as lists of elements (subset-lex order). We obtain algorithms for various combinatorial objects such as the subsets of a multiset, compositions and partitions represented as lists of parts, and for certain restricted growth strings. The algorithms are often loopless an...

WWW and the Internet - Did We Miss the Boat? (Panel)

Clearly, there is a plethora of database issues that are relevant to the Web. Examples include data visualization, scalability of data servers, caching and replication, data heterogeneity and intergration, query languages, etc. An important question, however, is whether the Web environment brings anything fundamentally new to these areas. Beside the database community, Web-related issues concer...

Sialyl-Tn in Cancer: (How) Did We Miss the Target?

Sialyl-Tn antigen (STn) is a short O-glycan containing a sialic acid residue a2,6-linked to GalNAca-O-Ser/Thr. The biosynthesis of STn is mediated by a specific sialyltransferase termed ST6GalNAc I, which competes with O-glycans elongating glycosyltransferases and prevents cancer cells from exhibiting longer O-glycans. While weakly expressed by fetal and normal adult tissues, STn is expressed b...

Did We Miss Something? Correspondence Analysis of Usability Data

We have applied a multivariate exploratory technique called Correspondence Analysis (CA) to create and analyze a model of the dataset of experiment results. The dataset originates from a comparative usability study of tracing with the use of mouse, pen, and touch input and contains both categorical and continuous data – i.e. results of questionnaires and task measurements. CA allowed to visuall...
