Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

Molecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

Synchronized online simulation at field level for virtual sensing of web tension

Discover Applied Sciences
In industrial automation, online simulation should reflect a real mechatronic system as accurate as possible. However, the simulation could drift away from the real manufacturing process due to imprecise modeling or changing system behavior.

Virtually Increasing the Measurement Frequency of LIDAR Sensor Utilizing a Single RGB Camera

IEEE Open Journal of Vehicular Technology
The frame rates of most 3D LIDAR sensors used in intelligent vehicles are substantially lower than current cameras installed in the same vehicle. This research suggests using a mono camera to virtually enhance the frame rate of LIDARs, allowing the more ...

Cascading Fault Analysis and Control Strategy for Computer Numerical Control Machine Tools Based on Meta Action

IEEE Access, 2019
Cascading faults of computer numerical control machine tools will lead to frequent machine faults, but an effective fault analysis and control strategy can significantly reduce the frequency of such cascading faults.

Control Strategies for Open-End Winding Drives Operating in the Flux-Weakening Region [PDF]

, 2013
This paper presents and compares control strategies for three-phase open-end winding drives operating in the flux-weakening region. A six-leg inverter with a single dc-link is associated with the machine in order to use a single energy source.

MITF maintains genome stability in nonmelanocyte lineages

Molecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

Field weakening control of a PM vehicle drive

The Journal of Engineering, 2019
This paper develops a new field weakening method for an integrated permanent magnet synchronous machine vehicle drive. This method adopts both the DC-link and the rotor speed as a feedback signals to generate the demagnetising current reference.
