Van der Waals ferroelectric semiconductor tunnel junction with ultra‐low switching voltage

InfoMat, EarlyView.
Ferroelectric tunnel junctions are promising building blocks for energy‐efficient memory and brain‐inspired computing, but their practical use is limited by the relatively high voltages required for operation. Here, we develop an all‐two‐dimensional ferroelectric tunnel junction based on AgBiP2Se6 that enables reliable memory operation below 0.2 V and ...

A Review of Robotic Surgery: Engineering Considerations and Future Directions From Surgeons' Perspectives

The International Journal of Medical Robotics and Computer Assisted Surgery, Volume 22, Issue 5, October 2026.
ABSTRACT Introduction Since its initial inception, robotic‐assisted minimally invasive surgery (RAMIS) is continually being applied to a wider array of procedures. However, there are significant limitations in current surgical subsystems, including a large learning curve, lack of effective haptic feedback, decreased surgical intuition, and decreased ...

Detecting Loosening of Bolt‐Flanged Pipe Using Smoothed Pseudo Wigner–Ville Distribution: Digital Twin‐Based Approach Using Convolution Neural Networks

International Journal of Mechanical System Dynamics, Volume 6, Issue 3, Page 407-424, September 2026.
ABSTRACT In this paper, an integrated digital twin‐based fault‐diagnosis framework is proposed to detect bolt loosening in flanged pipe connections. The approach combines finite element‐based numerical modeling, experimental modal analysis, and advanced signal processing‐assisted deep learning to achieve reliable loosening detection under operational ...

Optimal Sensor Placement for Inverse Finite Element Reconstruction of Three-Dimensional Frame Deformation

International Journal of Aerospace Engineering, 2018
The inverse finite element method (iFEM) for the 3D framework deformation reconstruction was introduced. As the process of iFEM did not require a priori knowledge, such as the modal shape, the loading, and the elastic-inertial material information of the
