The cuticles of most springtails (Collembola) are superhydrophobic, but the mechanism has not been described in detail. Previous studies have suggested that overhanging surface structures play an important role, but such structures are not a universal trait among springtails with superhydrophobic cuticles. A novel wetting experiment with a fluorescent dye revealed the extent of wetting on expos...

The utilization of unbounded external reinforcing bars is one of the strengthening methods used after loading stage and before failure. The method has been used in different forms to strengthen members of reinforced concrete structures. To investigate the effect of utilization of post-tensioned reinforcing bars in this method of strengthening, a number of reinforced concrete beams was tested. S...

Truss structures composed of members that work exclusively in tension or compression appear several problems science and engineering, e.g., the study resisting mechanisms masonry structures, as well design spider web-inspired web structures. This generalizes previous results on existence cable webs are able to support assigned sets nodal forces under tension. We extend such a problem limit anal...

We contribute interaction designs and an experiment that explore the design space of multi-stroke phrasing techniques for pen interfaces. Our experiment evaluates several techniques for actively maintaining muscle tension. We use these results to show how muscular tension can reduce the need for selection or tool modes in pen interfaces, and discuss various phrase structures supporting scope, c...

A brief summary will be given of the putative etiological factors/topography that so far have been discussed in the context of cervicogenic headache (CEH), in approximately sequential order. Some of these factors have some basis in clinical research and practice; others are more speculative.

We propose a new theoretical framework for understanding simultaneous trust and distrust within relationships. grounded in assumptions of multidimensionality and the inherent tensions of relationships. and we separate this research from prior work grounded in assumptions of unidimensionality and balance. Drawing foundational support for this new framework from recent research on simultaneous po...
