In this paper we discuss the problem of alignment of patterns under arbitrary rotation. When a generic image pattern is geometrically transformed, it typically spans a (possibly nonlinear) manifold in a high dimensional space. When the pattern of interest ...
The potential role of Hox genes during vertebrate limb development was brought into focus by gene expression analyses in mice (P Dolle, JC Izpisua-Belmonte, H Falkenstein, A Renucci, D Duboule, Nature 1989, 342:767-772), at a time when limb growth and patt ...
This thesis deals with applications of Lie symmetries in differential geometry and dynamical systems. The first chapter of the thesis studies the singular reduction of symmetries of cosphere bundles, the conservation properties of contact systems and their ...
Creating many different complex structures from a single prepattern is achieved from either a master mold or stamping onto a solid substrate by patterning with a PDMS replica mold. Various metal patterns including ellipses, dots, rings, chains of dots (or ...
Software transactional memory (STM) is a promising technique for controlling concurrency in modern multi-processor architectures. STM aims to be more scalable than explicit coarse-grained locking and easier to use than fine-grained locking. However, STM im ...
The use of chemical nanopatterns through nanoimprint lithography ato align a nematic liquid crystal (LC) in LC cells was described. It was found that the ratio of areas with different surface-aligning helped in the polar orientation of LC, while the azimut ...
Organophosphorus compounds found applications in varied fields of the organic chemistry: they are particularly present in natural compounds such as the deoxyribonucleic acid (DNA) and in the field of catalysis in which their utility is also proven. Thus, t ...
Bone is a natural composite construct, with a gradient structure going from a loose interconnected cellular core to an outer dense wall, thus minimizing bone weight while keeping a high mechanical resistance. Due to this unique and complex structure, bone ...
Software transactional memory (STM) is a promising technique for controlling concurrency in modern multi-processor architectures. STM aims to be more scalable than coarse-grained locking and easier to use than fine-grained locks. However, STM implementatio ...
In this article, we describe a novel hardware platform aimed at the realization of cellular architectures. The system is built hierarchically from a very simple computing unit, called ECell. Several of these units can then be connected, using a high-speed ...
