Estimating regional deformation of the myocardium from Cine MRI has the potential to locate abnormal tissue. Regional deformation of the left ventricle is commonly estimated using either segmentation or 3D+t registration. Segmentation is often performed at each instant separately from the others. It can be tedious and does not guarantee temporal causality. On the other hand, extracting regional...

Given the set of square matrices M ⊂ Mn+m(C) that keep the subspace W = Cnx{0} ⊂ C invariant, we obtain the implicit form of a miniversal deformation of a matrix a ∈ M, and we compute it explicitely when this matrix is marked (this is, if there is a permutation matrix p ∈ Mn+m(C) such that p−1ap is a Jordan matrix). We derive some applications to tackle the classical Carlson problem.

This paper deals with the reshaping technology for realizing three-dimensional (3-D) microstructures through plastic deformation of single-crystal silicon (SCS) films by applying Joule heating. SCS beams are used for determining the behavior of SCS microstructures during reshaping. The reshaped SCS structure has a sharp corner at a point where stress and heat are concentrated. The plastic defor...

A new method of three-dimensional (3-D) analysis of sclerotised structures of monogenoids was performed by processing z-series images using 3D-Doctor. Z-series were obtained from Gomori's trichrome-stained specimens of marine and freshwater monogenoids under laser scanning confocal fluorescence microscopy. Measurements obtained from 3-D images were then compared with those from 2-D images taken...

I construct a map from the Grothendieck group of coherent sheaves to Khomology. This results in explicit realizations of K-homology cycles associated with D-brane configurations. Non-Abelian degrees of freedom arise in this framework from the deformation quantization of N -tuple cycles. The large N limit of the gauge theory on D-branes wrapped on a subvariety V of some variety X is geometricall...

A common problem encountered in recognizing signs in realscene images is the perspective deformation. In this paper, we employ a descriptor named Cross Ratio Spectrum for recognizing real scene signs. Particularly, this method will be applied in two different ways: recognizing a multi-component sign as an whole entity or recognizing individual components separately. For the second strategy, a g...

Non-geometric string backgrounds were proposed to be related to a nonassociative deformation of the space-time geometry. In the flux formulation of double field theory (DFT), the structure of mathematically possible non-associative deformations is analyzed in detail. It is argued that on-shell there should not be any violation of associativity in the effective DFT action. For imposing either th...

An intrinsically soft and stretchable multicolor display and touch interface is reported. Red, green, and blue pixels are formed separately by photopatterning transition-metal-doped ZnS embedded in silicone gels and transfer printing onto an elastomeric dielectric sheet. The device shows stable illumination while being stretched up to 200% area strain or under different deformation modalities. ...
