Ziplock Snakes
, 1997
"... We propose a snake-based approach that allows a user to specify only the distant end points of the curve he wishes to delineate without having to supply an almost complete polygonal approximation. This greatly simplifies the initialization process and yields excellent convergence properties. This is ..."

onto the image contour in a manner reminiscent of a ziplock being closed. These snakes can be used to alleviate the often repetitive task practitioners face when segmenting images by eliminating the need to sketch a feature of interest in its entirety, that is, to perform a painstaking, almost complete
Computing the cardinality of CM elliptic curves using torsion points
, 2008
"... Let E be an elliptic curve having complex multiplication by a given quadratic order of an imaginary quadratic field K. The field of definition of E is the ring class field Ω of the order. If the prime p splits completely in Ω, then we can reduce E modulo one the factors of p and get a curve E define ..."

defined over Fp. The trace of the Frobenius of E is known up to sign and we need a fast way to find this sign. For this, we propose to use the action of the Frobenius on torsion points of small order built with class invariants à la Weber, in a manner reminiscent of the Schoof-Elkies-Atkin algorithm
Flagellar protein localization mediated by a calcium-myristoyl/palmitoyl switch mechanism
- EMBO J
, 1999
"... The mechanisms by which proteins are targeted to flagella and cilia are poorly understood. We set out to determine the basis for the specific localization of a 24 kDa flagellar calcium-binding protein (FCaBP) expressed in all life cycle stages of Trypanosoma cruzi. Through the study of trypanosome ..."

possessing these acyl modifications. Both fatty acids are required for flagellar localization, suggesting that FCaBP localization may be mediated through association with the flagellar plasma membrane. Indeed, FCaBP associates with the flagellar membrane in a calcium-dependent manner, reminiscent
Physiological Manner Simulates in Vivo Growth Patterns and Allows Discrimination of Cell Type1
, 2013
"... We cultured primary human mammary epithelial cells from five re duction mammoplasties and five breast carcinomas and attempted to improve culture conditions and define cell populations grown. Normal cells cultured on Matrigel basement membrane-like substance formed multicellular three-dimensional st ..."

This re-creation of normal and malignant breast cell mor phology may facilitate studies of breast cancer cell
Evolution of insect mushroom bodies: old clues, new insights
- Arthropod Struct. Dev
, 2005
"... The mushroom bodies are a morphologically diverse sensory integration and learning and memory center in the brains of various invertebrate species, of which those of insects are the best described. Insect mushroom bodies are composed of numerous tiny intrinsic neurons (Kenyon cells) that form calyce ..."

Deformable Velcro Surfaces
- CVIU SUBMISSION
"... Even though methods based on the use of deformable models have become prevalent, the quality of their output depends critically on the model's initial state. The issue of initializing such models, however, has not received much attention even though it is often key to the implementation of a tr ..."

Adaptive Time Horizon Optimization in Model Predictive Control”. American Control Conference,
, 2011
"... Abstract-Whenever the control task involves the tracking of a reference signal the performance is typically improved if one knows the future behavior of this reference. However, in many applications, this is typically not the case, e.g., when the reference signal is generated by a human operator, a ..."

Extension of Koiter’s linear shell theory to materials exhibiting arbitrary symmetry
- Int. J. Eng. Sci
, 2012
"... Abstract: Koiter’s linear shell theory applies to isotropic elastic materials and to anisotropic materials that exhibit reflection symmetry of the elastic properties with respect to the shell midsurface. To the extent that such shells are exceptional, classical linear shell theory is incomplete. Thi ..."

This lacuna is addressed here through a systematic procedure, applicable equally to all kinds of material symmetry, which entails an expansion of the potential energy of the shell in powers of its thickness in a manner reminiscent of Koiter’s work. The variables are the displacement field of the shell
