STAR-XPC: Set Transformer for Estimating X-ray Transmission in Polymer Composites

arXiv cs.LG ↗ · 3d ago Cached

STAR-XPC提出一个Set Transformer神经网络,直接将聚合物复合材料的分子组成与物理描述符映射为X射线透射率,推理仅需1-3毫秒,相比PENELOPE蒙特卡罗模拟加速数个数量级,同时达到R²=0.9988的高精度。

We've flown a radiation-blocking vest to the Moon and back, and it worked

Ars Technica ↗ · 2026-08-13 Cached

StemRad and Lockheed Martin successfully tested a radiation-blocking vest on a round trip to the Moon, demonstrating that targeted shielding of vulnerable organs reduces effective radiation dose by 60% without covering the head or limbs.
