Web navigation is a complex activity in which users interact with a system to achieve their goals. Current webnavigation models (Kitajima, Blackmon, & Polson, 2000; Miller & Remington, 2000; Pirolli & Fu, 2003) are based on the label-following strategy, which takes the semantic aspects of navigation elements as fundamental. We propose that goal-directed actions of users are supported by semanti...

Although at least one quarter of early-type barred galaxies host secondary stellar bars embedded in their large-scale primary counterparts, the dynamics of such double barred galaxies are still not well understood. Recently we reported success at simulating such systems in a repeatable way in collisionless systems. In order to further our understanding of double-barred galaxies, here we charact...

Piezoelectric vibratory tactile sensors are used for measuring the softness and hardness of an object. In this research, the sensitivity of the longitudinal bar type tactile sensor was considered to establish the design guideline of the vibratory tactile sensor. First, the sensitivity on the frequency change of the longitudinal bar resonator in contact with an object was approximately derived f...

BAR superfamily domains shape membranes through poorly understood mechanisms. We solved structures of F-BAR modules bound to flat and curved bilayers using electron (cryo)microscopy. We show that membrane tubules form when F-BARs polymerize into helical coats that are held together by lateral and tip-to-tip interactions. On gel-state membranes or after mutation of residues along the lateral int...

BACKGROUND The Nuss procedure is a minimally invasive technique using a retrosternal bar to repair pectus excavatum. Although its technical simplicity and cosmetic advantages are remarkable, early applications have been limited to children with symmetrical pectus excavatum. We report a large single-institution experience including technical modifications to correct asymmetric configurations and...

The Bin1/amphiphysin/Rvs167 (BAR) domain proteins are a ubiquitous protein family. Genes encoding members of this family have not yet been found in the genomes of prokaryotes, but within eukaryotes, BAR domain proteins are found universally from unicellular eukaryotes such as yeast through to plants, insects, and vertebrates. BAR domain proteins share an N-terminal BAR domain with a high propen...

The division of galaxies into " barred " (SB) and " normal " (S) spirals is a fundamental aspect of the Hubble galaxy classification system. This " tuning fork " view was revised by de Vaucouleurs, whose classification volume recognized apparent " bar strength " (SA, SAB, SB) as a continuous property of galaxies called the " family ". However, the SA, SAB, and SB families are purely visual judg...
