Downward nominal wage rigidity in Poland [PDF]
We use data on enterprise level from a survey of medium sized and big companies to test for downward nominal wage rigidity in Poland. We find relatively weak support for downward nominal wage rigidity when average total compensation in the enterprise is ...

The molecular design strategy that integrates both side chain and backbone engineering in diketopyrrolopyrrole‐based conjugated polymers to identify the optimal balance between doping efficiency and microstructural order is demonstrated. Comprehensive spectroscopic, electrochemical, morphological, and structural characterizations reveal that the ...

The behaviors of semiflexible polymers such as DNA and protein are often reshaped by coupled interactions. Monte Carlo simulations assist in studying these systems. This work recasts the traditional chain‐growth strategy into a new framework: a fixed number of chains grow synchronously, while less relevant chains to the target system are removed and ...

Torsional rigidity in beams with arbitrary cross-sections [PDF]
In solid mechanics, when a torque is applied on a body, the body twists. This is called torsion. In those sections which are perpendicular to the torque axis, the resultant shear stress is in a direction, perpendicular to that of the radius.

Existing soft pumps often require tradeoffs between performance and compatibility with soft robotic systems. The proposed trielectrode electrostatic soft pump addresses these limitations through an innovative driving mechanism. Its design, which includes a trielectrode configuration and the use of compliant materials, improves operational efficiency ...

Double Helix Structure for Stable Flexural Actuation in Soft Robotics
This work introduces a double‐helical architecture for soft robotic actuators that enhances twisting resistance, increases output force, and minimizes undesired deformation. Actuators driven by shape‐memory alloy wires exhibit a roughly fivefold higher torsional/flexural stiffness ratio and 50% greater force output.
