Recent studies implicate Wnt/beta-catenin signaling in lens differentiation (Stump, R. J., et al., 2003. A role for Wnt/beta-catenin signaling in lens epithelial differentiation. Dev Biol;259:48-61). Beta-catenin is a component of adherens junctions and fu ...
The design, simulation, fabrication and characterization of 3-D modulable micro-optical system based on poly-dimethilsiloxane (PDMS) are presented in this paper. This system consists on two uncoupled PDMS lenses with different diameter (2 and 10 mu m). Und ...
The use of large speech corpora in example-based approaches for speech recognition is mainly focused on increasing the number of examples. This strategy presents some difficulties because databases may not provide enough examples for some rare words. In th ...
We address the problem of computing n-finger force-closure grasps of 3D objects. As 3D force-closure grasps involve 6D wrench space, we use Pl¨ucker coordinates and Grassmann algebra, to demonstrate that wrenches associated to any three non-aligned contact ...

Graded-Index (GRIN) lenses with a diameter of 125 μm are presented. This diameter enables the assembly of the GRIN lenses onto an optical micro-system using the same passive alignment grooves as used for the light carrying optical fibers. In contrast to re ...
Increased intraocular pressure (IOP) is the leading cause and the hallmark of Glaucoma, an asymptomatic and irreversible degenerative disease that, undetected or untreated, progresses to blindness due to optic nerve atrophy. Glaucoma is the second cause of ...
PURPOSE. To present a novel and minimally invasive approach to intraocular pressure (IOP) monitoring based on a sensing contact lens. METHODS. The key element of this measurement method is a soft contact lens with an embedded microfabricated strain gauge a ...
We propose a novel approach to intraocular pressure (IOP) measurement allowing minimal invasive continuous monitoring over prolonged periods, regardless of patient position and activities [1]. The key element of this innovative measurement method is a soft ...
A new noninvasive approach for intraocular pressure (IOP) measurement allowing continuous monitoring over prolonged periods, regardless of patient's position and activities. The key element of this measurement method is a soft contact lens (1) including at ...
