Using a modified foam evaluation, we give categorification of the Alexander polynomial knot. We also purely algebraic version this knot homology which makes it appear as infinite page spectral sequence starting at reduced triply graded link Khovanov--Rozansky.

COVER ILLUSTRATION: The cover image is based on the Original Article Guided bone regeneration of chronic non-contained defects using a volume stable porous block TiO2 scaffold: An experimental in vivo study by Minh Khai Le Thieu et al., https://doi.org/10.1111/clr.13708.

The RR Page charges for the D2-, D4-, D6-brane in B fields are constructed explicitly from the equations of motion and the nonvanishing (modified) Bianchi identities by exploiting their properties — conserved and localized. It is found that the RR Page charges are independent of the backgound B fields, which provides further evidence that the RR Page charge should be quantized. In our construct...

Contemporary Internet search engine can hardly cope with enormous amount of indexed data, and very seldom succeed in extracting useful information. In order to anticipate usefulness of a web page, proposed solution keeps track of users actions on a web page. A modified web client informs a dedicated server of users' actions performed on a web page, such as printing, bookmarking or mailing. Latt...

We modified a time-lapse recording to make a ‘flipbook’ of zebrafish embryogenesis. By flipping through the pages of this issue and watching the pictures in the upper corner of each even-numbered page, the dynamic cellular movements that form the zebrafish embryo can be visualized. The time-lapse record starts at the 2-cell stage (page 2 and Fig. 1B) and ends at the 16-somite stage (Fig. 1I), a...
