The structure is a lightweight wrapper around standard dense/sparse matrix parameters and does not own any data arrays. Matrix objects are used to pass matrix of the linear system, as well as solution and right-hand side (even if these are in fact vectors). Currently, cuDSS matrix objects...
Scrattch.bigcat adopted the parquet file format for storing sparse matrix, which allows for manipulation of matrices that are too large to fit in memory through memory mapping to files on disk. The whole gene-count matrices were chunked to smaller parquet files with bin size of 50,000 for c...
Each column of a relational database has the same number of rows, but some of the fields have a null value or appear to be empty. In wide-column databases, empty rows simply do not exist for a particular column. The column families reside in a keyspace. Each keyspace holds an ent...
waves extracted by CPCA account for much of the global spatial structure found in human resting-state functional MRI as previously studied15. Additionally, we utilized weighted gene coexpression network analysis (WGCNA)38to analyze the gene expression data and investigated the relationships between genes...
It could be used more broadly to generate different types of viral vector, and any large, therapeutically valuable proteins, where available data are sparse. This is a preview of subscription content, access via your institution Access options Access through your institution Access Nature and 54...

Layer 4 (L4) of mammalian neocortex plays a crucial role in cortical information processing, yet a complete census of its cell types and connectivity remains elusive. Using whole-cell recordings with morphological recovery, we identified one major excita
(NPUs), Vector Processing Units (which perform the same operation on multiple data elements simultaneously), specialized instructions like matrix multiplication, and optimized software and compilers for AI tasks. However, most AI-optimized CPUs still lag behind state-of-the-art AI chipsin terms of...
