The Allotrope Foundation is a consortium of pharmaceutical companies, instrument vendors and software companies to simplify the exchange of scientific electronic data. It publishes the Allotrope Foundation Ontology (AFO) which is a controlled vocabulary to structure data, the Allotrope Data Models (ADM) and the Allotrope Data Format (ADF) based on HDF5 which incorporates those for use in practice.
In DNA double helix, the two strands of DNA are held together by hydrogen bonds. The nucleotides on one strand base pairs with the nucleotide on the other strand. The secondary structure is responsible for the shape that the nucleic acid assumes. The bases in the DNA are classified as purines and pyrimidines. The purines are adenine and guanine ...
Hierarchical Data Format (HDF) is a set of file formats (HDF4, HDF5) designed to store and organize large amounts of data.Originally developed at the U.S. National Center for Supercomputing Applications, it is supported by The HDF Group, a non-profit corporation whose mission is to ensure continued development of HDF5 technologies and the continued accessibility of data stored in HDF.
The Sun Microsystems-built Tsubame 1.0 began operation in 2006 achieving 85 TFLOPS of performance, it was the most powerful supercomputer in Japan and Asia at the time. [1] [2] [3] The system consisted of 655 InfiniBand connected nodes, each with a 8 dual-core AMD Opteron 880 and 885 CPUs and 32 GB of memory.
Given the difference in widths of the major groove and minor groove, many proteins which bind to DNA do so through the wider major groove. [6] Many double-helical forms are possible; for DNA the three biologically relevant forms are A-DNA, B-DNA, and Z-DNA, while RNA double helices have structures similar to the A form of DNA.
Zhipu AI, Sophgo and entities linked to them were among 25 China-based companies and two Singapore-based companies added to the U.S. Commerce Department's Entity List, according to government ...
The researchers disagree, saying that the tattoos were puncture-based. Tattoos permeate ancient society as far back as Ötzi the Iceman —Europe’s oldest-known human mummy.
DNA and RNA also contain other (non-primary) bases that have been modified after the nucleic acid chain has been formed. In DNA, the most common modified base is 5-methylcytosine (m 5 C). In RNA, there are many modified bases, including those contained in the nucleosides pseudouridine (Ψ), dihydrouridine (D), inosine (I), and 7-methylguanosine ...
