New theory offers insights into the origin of the very low and negative thermal expansion observed in cordierite ...

Analysis of the crystal structure revealed a three-dimensional lattice of TiO 6 octahedra and PO 4 tetrahedra with an open, flexible structure that contains both "cavities" and "channels," where ...

CIRCLES which touch cyclically may be called a ring. Two rings will touch when each member of the one touches each member of the other ; and so for spheres.

表面估计 为了估计几何形状，使用浅层MLP对三平面进行查询，以生成密度值。 使用可变行进四面体（Deep marching tetrahedra，DMTet）将隐式密度场转换为显式曲面。 此外，还使用两个MLP头来预测点偏移和表面法线以及密度。 这两个属性减少了行进四面体所带来的 ...

Chemistry is a core science subject that touches almost every aspect of our daily lives and will become increasingly important in our future knowledge-based society. Chemists develop life-saving drugs ...
