Neural Coding of Green Flash in Retinal Bipolar Pathways [PDF]
, 2012 What visual information do the graded potentials among retinal bipolar pathways actually transmit from photoreceptors to ganglion cells? The answer does not exist. Even the graded electric signals have not been understood completely.

Parallel Planning Mechanisms as a "Recipe for Disaster" [PDF]
Potchefstroom Electronic Law Journal, 2010 This note offers a critical reflection of the recent landmark decision in City of Johannesburg Metropolitan Municipality v Gauteng Development Tribunal which lay to rest the negative consequences of employing the DFA procedures of the Development ...

Type Synthesis of Fully-Decoupled Three-Rotational and One-Translational Parallel Mechanisms
International Journal of Advanced Robotic Systems, 2016 Based on screw theory and the principle of one- leg driving by an independent motor, a methodology for the structural synthesis of fully-decoupled three-rotational and one-translational (3R1T) parallel mechanisms is proposed by analysing the ...

First Principles Simulations of Boron Diffusion in Graphite [PDF]
, 2007 Boron strongly modifies electronic and diffusion properties of graphite. We report the first ab initio study of boron interaction with the point defects in graphite, which includes structures, thermodynamics, and diffusion. A number of possible diffusion

Type Synthesis of 4-DOF Non-Overconstrained Parallel Mechanisms with Symmetrical Structures
Machines, 2022 This paper presents the type synthesis of 4-DOF non-overconstrained parallel mechanisms (PMs) with symmetrical structures. A special topological structure that includes two intermediate platforms and one moving platform is employed. Constraint conditions

Probabilistic motion planning for parallel mechanisms [PDF]
2003 IEEE International Conference on Robotics and Automation (Cat. No.03CH37422), 2004 Despite the increasing interest in parallel mechanisms during the last years, few researchers have addressed the motion planning problem for such systems. The few existing techniques lie in a representation of the workspace of the mechanism (or its boundary).

Novel Kinematically Redundant (3+1)-DOF Delta-Type Parallel Mechanisms
RoboticsAlthough parallel mechanisms are used in various fields, their application is often limited by singularities and a restricted workspace. Kinematic redundancy is a promising approach for mitigating these issues while also extending the functionality of ...

Similar genetic mechanisms underlie the parallel evolution of floral phenotypes. [PDF]
PLoS ONE, 2012 The repeated origin of similar phenotypes is invaluable for studying the underlying genetics of adaptive traits; molecular evidence, however, is lacking for most examples of such similarity.
