Falling accidents are costly due to their prevalence in the workplace. Slipping has been known to be the main cause of falling. Understanding the motor response used to regain balance after slipping is crucial to developing intervention strategies for effective recovery. Interestingly, studies on spinalized animals and studies on animals subjected to electrical microstimulation have provided ma...

Slipping detection and avoidance are key issues in dexterous robotic manipulation. The capability of robots to grasp manipulate objects common use can be greatly enhanced by endowing these with force/tactile sensors on their fingertips. Object slipping caused both tangential torsional loads when the grip force is too low. Contact moment measurements required counteract such avoid slippage contr...

We reviewed the radiological and clinical long-term results after the nailing in situ of slipped upper femoral epiphysis in 59 hips in 43 patients. The displacement of the epiphysis had been measured as the 'slipping angle' before operation and related to the results at follow-up at a mean of 30.9 years (27 to 34). The mean age at follow-up was 44.2 years (39 to 50). Radiographic re-examination...

Slipping and tripping contribute to a large number of falls and fall-related injuries. While the vestibular system is known to contribute to balance and fall prevention, it is unclear whether it contributes to detecting slip or trip onset. Therefore, the purpose of this study was to investigate the effects of slipping and tripping on head acceleration during walking. This information would help...

OBJECTIVES Falls are a leading cause of injury at work, and slipping is the predominant cause of falling. Prior research has suggested a modest correlation between objective measures (such as coefficient of friction, COF) and subjective measures of slipperiness (such as worker perceptions) in the workplace. However, the degree of association between subjective measures and the actual risk of sl...

Sand lances, fishes in the genus Ammodytes, exhibit a peculiar burrowing behavior in which they appear to swim rapidly into the substrate. They use posteriorly propagated undulations of the body to move in both water, a Newtonian fluid, and in sand, a non-Newtonian, granular substrate. In typical aquatic limbless locomotion, undulations of the body push against water, which flows because it is ...

Biomechanical aspects of slips and falls have been widely studied to facilitate fall prevention strategies. Prior studies have shown changes in gait after an induced slipping event. As such, most researchers only slip participants one time to avoid such changes that would otherwise reduce the external validity of experimental results. The ability to slip participants more than once, after allow...

The SAGE adviser and Wellcome Trust director tells Mun-Keat Looi how the UK government acted too slowly against pandemic, about perils of vaccine nationalism, why he is bullish controlling covid variants

‘‘And now here it was again, now grown, now in its new home.’’ In her book Resilience, Elizabeth Edwards recalls what raced through her mind when she learned that her cancer had come back and had metastasized. After surgery, radiation, and chemotherapy, she thought that the cancer ‘‘had been chased away.’’ How does cancer find a new home and become metastatic? The short answer is simple: it is ...
