Smart photo sticking is a novel strategy to automatically arrange a collection of photos in a pleasant collage. The proposed approach improves previous solutions both considering a self-adaptive image cropping algorithm, exploiting visual and semantic information, and introducing an optimization process based on a genetic algorithm. Preliminary results confirm the effectiveness of the proposed ...

Assuming a reemission model, we have studied, in detail, the effect of sticking coefficient on the morphology evolution in low-pressure chemical vapor deposition processes. We have shown that the surface morphology changes from a self-affine fractal to a columnarlike morphology with increasing sticking coefficient, which agrees qualitatively with experimental observations.

In This Issue In This Issue Let's make liver etoxification is what livers do best, and regenerating after toxic insults is what livers do second best. All that proliferative capacity suggests that liver stem cells might be a very different and more prevalent beast than stem cells from other organs. But, on page 173, Suzuki et al. report that the fetal mouse liver, just like the adult bone marro...

ntercalation—the slotting of cells in between one another—is an established method for converting short and fat into long and slim. This is all very well in slippery, adhesion-sparse mesenchymal tissues. But many such extension events occur in epithelial tissues, where cells are glued together by adhesion complexes. Claire Bertet, Lawrence Sulak, and Thomas Lecuit (IBDM, Marseille, France) now ...

espanolThe aim of this study was to analyze the Sticking Region at submaximal (70%, 80%, 90% until failure) and maximal (1RM) loads in concentric phase during bench press. Eleven male individuals participated (age: 22.73 ± 2.57 years, body mass: 80.2 6.9 kg, height: 179.6 7.4 cm, 1RM: 94.55 11.56 kg) with least two years press training experience. In our sample, The could only be observed 100% ...

If two elastic bodies with rough surfaces are first pressed against each other and then loaded tangentially, sliding will occur at the boundary of the contact area while the inner parts may still stick. With increasing tangential force, the sliding parts will expand while the sticking parts shrink and finally vanish. In this paper, we study the fractions of the contact area, tangential force an...

Chemokines have been hypothesized to contribute to the selectivity of lymphocyte trafficking not only as chemoattractants, but also by triggering integrin-dependent sticking (arrest) of circulating lymphocytes at venular sites of extravasation. We show that T cells roll on most Peyer's patch high endothelial venules (PP-HEVs), but preferentially arrest in segments displaying high levels of lumi...
