ncbi vdb-3 NCBI's VDB is a highly compressed column-oriented data warehousing technology developed initially to address the needs of the Sequence Read Archive (SRA). It is unique in that it builds databases from smaller parts that can function independently as documents , supports effective and efficient compression, supports encryption while ...

This object is a small reflection nebula located 1000 light years away in the constellation of Cassiopeia at a declination of +69 degrees. The nebula surrounds the orange star HD 3037, which is an 8.4 magnitude star. The nebula is 3 arc-minutes long, which at that distance corresponds to a length of 1 light year.

2022年2月10日 · NCBI's SRA changed the source build system to use CMake in toolkit release 3.0.0. This change is an important step to improve developers' productivity as it provides unified cross platform access to support multiple build systems. This change affects developers building NCBI SRA tools from source.

VdB 3 is a small reflection nebula visible in the constellation Cassiopeia. It is situated near the border with the constellation Cepheus, about one degree to the northeast of the nebulous complex NGC 7822. The star that illuminates the cloud is an orange giant of magnitude 8.4, cataloged as HD 3037, whose light gives an orange color to the dust .

3.3，Neural VDB NeuralVDB 建立在 NanoVDB 的 GPU 加速之上，是一种新的混合数据编码方案，通过添加机器学习来引入紧凑的神经表示，从而显着减少其内存占用或加快查询速度。

vdB 3 est une petite nébuleuse diffuse, visible dans la constellation de Cassiopée [1].. Elle est située à la frontière avec la constellation de Céphée, à environ un degré au nord-est du complexe nébuleux de NGC 7822.L'étoile centrale illuminant le nuage est une géante rouge de magnitude 8,4, cataloguée HD 3037, dont la lumière donne à la poussière illuminée une couleur orangée.

这个程序大佬把官方没带来的功能做了！ 目前插件还是初发布阶段 期待后续的完善 Github:https://github.com/eidosmontreal/unreal-vdb 视频中的VDB下载网 …
