We prove a modularity lifting theorem for potentially BarosttiTate representations over totally real fields, generalising recent results of Kisin. Unfortunately, there was an error in the original version of this paper, meaning that we can only obtain a slightly weaker result in the case where the representations are potentially ordinary; an erratum has been added explaining this error.

We developed a 1‐DOF power assist robot system for lifting objects by two humans cooperatively. We hypothesized that weight perception due to inertia might be different from that due to gravity when lifting an object with power‐assist because the perceived weight differs from the actual weight. The system was simulated and two humans cooperatively lifted objects with ...

1. While subjects lifted a variety of commonly handled objects of different shapes, weights, and densities, the isometric vertical lifting force opposing the object's weight was recorded from an analog weight scale, which was instrumented with high-stiffness strain gauge transducers. 2. The force output was scaled differently for the various objects from the first lift, before sensory informati...

The humanoid robots are bio-inspired models of human body. The mechanical structure of humanoid robots consists of several joints and segments. Numerous degrees of freedom are caused the redundancy problem. There is an unanswered question concerning with strategies which central nervous system implements to predict the human posture and gesture during different movements. A 7 degree of freedom ...

Using the results of psychophysical and biomechanical experiments, NIOSH (National Institute for Occupational Safety and Health) Recommended Weight Limit (RWL), the Lifting Index (LI), the form of the asymmetry multiplier, and the criterion for compression force were investigated. Analysis of the results indicated a significant difference between the NIOSH RWL and the reported Maximum Acceptabl...

According to the Theory of Reasoned Action people act according to intentions (Ajzen & Fishbein, 1980). An individual’s perception of an activity influences intention to act, and can predict if a person will choose to engage in that activity. Although strength is identified as one of the five health-related fitness components (Corbin, Lindsey, & Welk, 2000), females often avoid the activity of ...

Power assist robots are usually used for disabled and elderly people to augment their abilities and skills. This paper proposes to use these robots to handle heavy objects in industries, and thus brings a novelty in the applications of power assist robots. However, it is difficult to optimize perceived heaviness and motion either independently or simultaneously for lifting objects with power-as...

The present paper describes an exercise model that produces a voluntary hindlimb weight-lifting response. Each rat was operantly conditioned to enter a vertical tube, insert its head into a weighted ring (either 70 g or 700 g), lift the ring until its nose interrupted an infrared detector, and then lower the ring. Load cells measured the external force generated, and displacement transducers me...

Lifting tasks that involve twisting have been repeatedly implicated as contributing to the onset of occupational back injuries in epidemiological studies. The objective of this work was to quantify the three directional external moments acting on the spine during a sagittally symmetric and two asymmetric lifting tasks. A total of 15 subjects participated in the three lifting tasks. All tasks we...
