In this article, a cognitive, metonymic approach will be applied to the well-known phenomenon that events denoted by non-derived denominal verbs do not necessarily involve referent of base noun (e.g. Sue hammered nail into wall with her shoe). particular, it argued shared sensorimotor experience as interaction basic-level objects like hammers, shelves, or bicycles facilitates interpretation res...

Bike Sharing Systems (BSSs) allow customers to rent bicycles at automatic rental stations distributed throughout a city, use them for a short period of time, and return them to any station. One of the major issues that BSS operators must address is non-homogeneous asymmetric demand processes. These demand processes create an inherent imbalance, thus leading to shortages of bicycles, when users ...

Electric scooter (e-scooter) use has increased internationally, with concerns about injuries to riders and pedestrians, reports of non-use helmets, excessive speed, drink-riding underage riding. E-scooter regulations vary widely among jurisdictions, likely effects on the extent nature safety issues. This study was conducted in downtown Brisbane, Australia, where e-scooters must be ridden footpa...

Isoprenoid precursors readily undergo (poly)cyclization in electrophilic reaction cascades, presumably as internal addition of the carbon-carbon double-bonds from neighboring isoprenyl repeats readily forms relatively stable cyclohexyl tertiary carbocation intermediates. This hypothesis is agnostic regarding alkene configuration (i.e., Z or E). Consistent with this, here it is shown that certai...

With the increasing number of bicycle riders, there is an increased risk of accidents between bicycles and automobiles. Some accidents are caused by speeding bicycles and the lack of communication between the cyclist and car drivers. To close the communication gap, we propose a method to detect speeding behaviors using a conventional smartphone. Using the smartphone, the cyclist will be able to...

As a major type of transportation equipments, bicycles, including electrical bicycles, are distributed almost everywhere in China. The accidents caused by bicycles have become a serious threat to the public safety. So bicycle detection is one major task of traffic video surveillance systems in China. In this paper, a method based on multi-feature and multi-frame fusion is presented for bicycle ...

A bike sharing system deploys bicycles at many open docking stations and makes them available to the public for shared use. These bikes can be checked-in and checked-out at any of the docking stations. Predicting daily visits is important for service providers to optimize bike allocation and station maintenance. In this paper, we formulate this prediction problem as a regression task. Through d...

Steering a motorcycle or bicycle is counterintuitive; to turn right, you must steer left initially, and vice versa. You can execute this initially counter-directed turn by turning the handlebars explicitly ~called counter-steering! or by throwing your hips to the side. Contrary to common belief, gyroscopic forces play only a limited role in balancing and steering @D. E. H. Jones, Phys. Today 23...

With the increasing popularity of electric-assist bikes (E-bikes) in China, U.S. and Europe, corresponding safety issues at intersections have attracted attention researchers. Understanding microscopic behavior E-bike riders during conflicts with other road users is fundamental for improvement simulation modeling E-bikes intersections. This study compared conflict avoidance behaviors convention...
