Researchers have discovered an underwater sinkhole so deep, they haven’t even reached the bottom yet. Taam Ja' Blue Hole ...

Abstract: In many fields, such as geological exploration, mining and oil exploitation, the prediction of borehole inclination angle and trajectory is a key problem. Accurate prediction is not only ...

Abstract: A generative deep learning (GDL)-enabled approach is developed for the multi-objective synthesis of dual-polarized, wide-angle loop-family frequency selective surfaces (FSSs) by proposing a ...

In the center of China’s Taklimakan Desert, engineers have started drilling a new scientific borehole. Their plan is to reach more than 32,800 feet straight down, roughly six miles into solid rock.

What looks like a massive crater quickly reveals itself as something far worse—a direct opening into the earth that drops hundreds of feet into darkness. Standing at the edge, the scale is hard to ...
