Bias deployable grids are meshes with two directions of rotation on the ground plan respect to edges. They offer benefits such as three-dimensional resistance supports around entire perimeter a rectangular layout, and consist exclusively load-bearing scissors opposed usual combinations bracing scissors. However, their angular distortion is limited, they require auxiliary elements maintain fully...

While in R2, every two polygons of the same area are scissors congruent (i.e., they can be both decomposed into the same finite number of pair-wise congruent polygonal pieces), in R3, there are polyhedra P and P ′ of the same volume which are not scissors-congruent. It is therefore necessary, given two polyhedra, to check whether they are scissorscongruent (and if yes – to find the correspondin...

This work focuses on the segmentation of axonal structures in digital images of organotypic slice co-cultures. An image processing chain is presented, which relies on anisotropic diffusion for preprocessing of the images and the intelligent scissors method for segmentation. This method requires manual user interaction to set the starting points. To overcome this drawback, the initial parameters...

Autophagic lysosome reformation (ALR) is a cellular process in which lysosomes are reformed through scission of protolysosomes from tubular structures extruded from autolysosomes. Despite recent progress, the molecular mechanism of ALR is far from clear. A paper in this issue of The EMBO Journal has identified lysosome-localized PI(3)P, which is generated by the VPS34–UVRAG complex in an mTOR-d...

THE problem of the perfect cataract section and how it should be made is prominent in the minds of ophthalmic surgeons. We are all aware that the success of a lens extraction is substantially dependent upon the accuracy of the section, and there are few of us who cannot recall tragedies or near-tragedies resulting from the improper opening of the eye. With this in mind, and in spite of average ...

We show that a Bose-Einstein condensate with a vortex lattice in a rotating anisotropic harmonic potential exhibits a very low frequency scissors mode. The appearance of this mode is due to the SO 2 symmetry breaking introduced by the vortex lattice. The corresponding Goldstone mode in an isotropic trap becomes, in an anisotropic trap, a scissors mode, whose frequency is finite and tends to zer...
