Development of a neural efficiency metric to assess human-exoskeleton adaptations
Frontiers in Robotics and AIPassive exoskeletons have been introduced to alleviate loading on the lumbar spine while increasing the wearer’s productivity. However, few studies have examined the neurocognitive effects of short-term human-exoskeleton adaptation.

Continuous Line Bucket Lifting Versus Pipe Lifting
, 2017 In the literature, the continuous line bucket (CLB) lifting system and the pipe lifting system (PLS), as two typical mineral lifting methods in deep sea mining (DSM) systems, have been discussed since the 1960s.

Lifting operations and lifting equipment
, 2013 Lifting operations are inherent to many occupations in the construction industry. They can be performed manually or using lifting equipment. Both manual lifting and mechanical lifting operations can put construction workers at great risk of injury or ...

Analysis of the force on the balance beam of the lifting device
MetalurgijaIn the process of hoisting the memorial archway, because the balance beam directly lifts the memorial archway, it is easy to deform during the hoisting process, and the deformation will affect the follow-up work, resulting in the delay of the project ...

Limits to the Hall Effect and Other Nonreciprocal Effects in Three‐Dimensional Metamaterials
Advanced Materials, EarlyView.Comprehensive and fundamental bounds on nonreciprocal effects in three‐dimensional metamaterials are derived. They reveal that the effective Hall mobility cannot exceed the largest constituent mobility, that, under certain conditions, the Verdet constant cannot be enhanced, and that, for constituents with Hall coefficients of the same sign, the largest

Advanced Materials, EarlyView.Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a
