Understanding the Dynamics of Mechanically Interlocked Molecular Systems via Metadynamics Simulations

The Chemical Record, EarlyView.
This Personal Account discusses how molecular simulations help uncover motion, shuttling mechanisms, and kinetics in mechanically interlocked molecules such as rotaxanes and catenanes. Mechanically interlocked molecules, such as rotaxanes and catenanes, display complex internal dynamics and reciprocal motions that are central to their use as artificial

Multi-axle Vehicle Modeling and Stability Control: A Reconfigurable Approach [PDF]

, 2019
Multi-axle vehicles, such as trucks and buses, have been playing a vital role in trucking industry, public transportation system, and long-distance transport services. However, at the same time, statistics suggest more than one million lives are lost in

Dynamic Envelope Optimization of Articulated Vehicles Based on Multi-Axle Steering Control Strategies

Actuators
Steer-by-wire technology, critical for autonomous driving, enables full-wheel steering in articulated vehicles, significantly enhancing maneuverability in complex driving environments. This study investigates dynamic envelope optimization for articulated

Striking for a Just Transition? North American Auto Unions and the Electric Vehicle Transition

Industrial Relations: A Journal of Economy and Society, EarlyView.
ABSTRACT Decarbonization heightens risks for workers, but union strategies shape how these risks are managed and whether new jobs offer quality employment. This paper compares U.S. and Canadian auto unions during the 2023 Detroit Three bargaining, focusing on strategic capacities and internal politics to explain their divergent responses to the EV ...

Study on control schemes of flexible steering system of a multi-axle all-wheel-steering robot

Advances in Mechanical Engineering, 2016
It is well known that a multi-axle wheeled robot possesses larger load capability and also higher drive performance. However, its steering flexibility is degraded due to the large number of wheels.

The role of behavioural measures in successful fishway passage during seasonal brown trout (Salmo trutta) migration

Journal of Fish Biology, EarlyView.
Abstract Successfully overcoming lateral barriers in rivers is crucial for longitudinal fish migration and is influenced mainly by fishway design, environmental variability and/or individual behavioural traits. Although behavioural traits are well studied in many contexts, their role in predicting fishway passage success in the wild remains poorly ...

Estimating National and Foreign Trade Elasticities Using Generalized Transport Costs

Journal of Regional Science, Volume 65, Issue 2, Page 471-496, March 2025.
ABSTRACT We introduce the definition of two distinct trade elasticities corresponding to imports from regions located in the same country (national elasticities) and foreign regions located in other countries (foreign elasticities). We resort to a three‐tier nested CES utility structure to derive the corresponding demand gravity equations.

Driverless Bus Path Tracking Based on Fuzzy Pure Pursuit Control with a Front Axle Reference

Applied Sciences, 2019
Currently, since the model of a driverless bus is not clear, it is difficult for most traditional path tracking methods to achieve a trade-off between accuracy and stability, especially in the case of driverless buses. In terms of solving this problem, a

Electronic Control of Motor Axles of Forestry Trailers

Croatian Journal of Forest Engineering : Journal for Theory and Application of Forestry Engineering, 2015
Timber transport in the forest is a very complex operation, and expensive from an energy point of view. Furthermore, in some cases, this operation can be very difficult and dangerous in unfavorable conditions of the road surface, which mainly occur in winter (frozen ground) and in spring (muddy ground).

First assessment of brush‐harvested native seed mixes in southern Brazilian grasslands

Restoration Ecology, EarlyView.
Abstract Introduction The restoration of grassland ecosystems in southern Brazil remains limited by the absence of a structured supply chain for native seeds and seedlings. Objectives Here, we present the first evaluation in Brazil of mechanized, multi‐species seed harvesting from native grassland remnants using a brush harvester.
