The origin of angiosperms has been a long-standing botanical debate. The great diversity of
angiosperms in the Early Cretaceous makes the Jurassic a promising period in which to …

Lithium-ion battery (LIB) is a broadly adopted technology for energy storage. With increasing
demands to improve the rate capability, cyclability, energy density, safety, and cost …

Back drilling technique is useful for high-speed printed circuit board (PCB) design. Currently,
the stub length is measured by the destructive method that involves cutting the PCB and …

Void inspection is crucial for insulated gate bipolar transistors. X-ray computed
laminography (CL) is an imaging method for plate-like objects such as insulated gate bipolar …

Limited-angle computed tomography (CT) imaging is one of the common imaging problems.
The reconstructed images often encounter obvious artifacts and structure degradation. In …

Cone-beam computed laminography (CBCL) is an X-ray three-dimensional imaging method
that is suitable for large plate-like objects. Geometric parameter calibration is crucial during …

Insulated gate bipolar transistor (IGBT) is a power semiconductor module. Voids may arise
in its solder process when a contaminant or gas is absorbed into the solder joint. They …
