It Takes Two Neurons To Ride a Bicycle
Past attempts to get computers to ride bicycles have required an inordinate amount of learning time (1700 practice rides for a reinforcement learning approach [1], while still failing to be able to ride in a straight line), or have required an algebraic analysis of the exact equations of motion for the specific bicycle to be controlled [2, 3]. Mysteriously, humans do not need to do either of th...

متن کاملLoads of Lower Limb Joints during Bicycle Ride
Abstract: This work features a geometric and static analysis of the lower limb during bicycle ride. Basic dimensions are indicated, which are necessary for the description of movement geometry. The simplified flat model was adopted for the analysis. Using the transformation of Denavit-Hartenberg frames, vectors were developed for the position of the rotation axis of the joints in immovable fram...
متن کاملCan You Ride a Bicycle? The Ability to Ride a Bicycle Prevents Reduced Social Function in Older Adults With Mobility Limitation
BACKGROUND The health benefits of bicycling in older adults with mobility limitation (ML) are unclear. We investigated ML and functional capacity of older cyclists by evaluating their instrumental activities of daily living (IADL), intellectual activity, and social function. METHODS On the basis of interviews, 614 community-dwelling older adults (after excluding 63 participants who never cycl...
متن کاملMy favorite cell--Paramecium.
A Paramecium cell has a stereotypically patterned surface, with regularly arranged cilia, dense-core secretory vesicles and subplasmalemmal calcium stores. Less strikingly, there is also a patterning of molecules; for instance, some ion channels are restricted to certain regions of the cell surface. This design may explain very effective and selective responses, such as that to Ca(2+) upon stim...
