Imagine shrinking Earth to the size of a small ball to reveal just how vast the Universe is. If it were 12 centimeters wide, Jupiter would stretch over a meter across beside it. But the Sun would be ...

City-scale building energy simulation provides a significant reference for planning and urban management. However, large-scale building energy simulation is often unfeasible due to the huge amount of ...

The object scale of a small object scene changes greatly, and the object is easily disturbed by a complex background. Generic object detectors do not perform well on small object detection tasks. In ...

Researchers have engineered a laser device smaller than a penny that they say could power everything from the LiDAR systems used in self-driving vehicles to gravitational wave detection, one of the ...

A research team from Tsinghua University says it has developed a 3D printing method capable of fabricating millimeter-scale objects in under a second, which is a dramatic improvement over most current ...
