The invention discloses a structure model of a distributed database. A method comprises the following steps: firstly establishing a distributed database management system, and establishing a central server and a data server; storing logical relation with other servers into the central server, ...
This material property performance evaluation approach, guided by the assumption of independent and identically distributed (i.i.d.) data, proved inadequate in replicating their performance in real-world material discovery applications. In practical scenarios, ML models are often utilized to discover or...
Intriguingly, the nucleosome particles from each class are distributed rather randomly without any spatial preference (Fig. 2b). Table 1 CryoET data collection and structure determination of native nucleosomes Full size table 3D organization of nucleosomes in native chromatin fibres The high quality ...
In Section “Database storage structure” we review the principles of page-based data storage in relational databases and define the parameters for parsing and recovering these pages. In the same section we also summarize important database-specific storage structures (i.e., non-tables) and ...
Analysis of the chemical space explored by machine learning The chemical space explored by the machine learning approach was inspected via dimensionality reduction techniques, including principal component analysis, t-distributed stochastic neighbor embedding49 and uniform manifold approximation and projection (...

As the underlying technology of Bitcoin, blockchain has received extensive attention [15–18]. Blockchain is a distributed database technology that has the characteristics of decentralization [19–21], traceability, tamper-proof, collective maintenance, etc. [22]. The emergence of this technology ...
Block-Interleaved Distributed Parity 采用了块级拆分且校验信息分布式存储,即数据和其他的数据的校验信息可以存储在同一个磁盘上,但是该数据自己的校验信息不能和自己存储在用一块磁盘上 一共5块磁盘做RAID,P0~P4表示纠错位(校验信息),数据块按照(n mod 5) + 1的方式存储在5块盘上,相应数据块的校验信息存储在...
Path queries are most useful when you'd like to fire a function against some part of your data (be it processing, database initialization or anything else.You can also run predicate queries based on your map, for example if you want to configure your database servers from rather big and ...
SeqHound has been developed as an integrated biological sequence, taxonomy, annotation and 3-D structure database system. It provides a high-performance server platform for bioinformatics research in a locally-hosted environment. SeqHound is based on the
