Lattice-based cryptography is the generic term for constructions of cryptographic primitives that involve lattices, either in the construction itself or in the security proof. Lattice-based constructions support important standards of post-quantum cryptography. [1] Unlike more widely used and known public-key schemes such as the RSA, Diffie ...
The Voynich manuscript is an illustrated codex, hand-written in an unknown script referred to as 'Voynichese.'. [18] The vellum on which it is written has been carbon-dated to the early 15th century (1404–1438). Stylistic analysis has indicated the manuscript may have been composed in Italy during the Italian Renaissance.
Critical green inclusions, also known as green neutrophilic inclusions and informally, death crystals or crystals of death, [1] [2] are amorphous blue-green cytoplasmic inclusions found in neutrophils and occasionally in monocytes. They appear brightly coloured and refractile when stained with Wright-Giemsa stain.
Potassium chromium sulfate. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Chrome alum or Chromium (III) potassium sulfate is the potassium double sulfate of chromium. Its chemical formula is KCr (SO 4) 2 and it is commonly found in its dodecahydrate form as KCr (SO 4) 2 ·12 (H ...
The Crystallography Open Database (COD) is a database of crystal structures. Unlike similar crystallography databases, the database is entirely open-access, with registered users able to contribute published and unpublished structures of small molecules and small to medium-sized unit cell crystals to the database.
A crystallographic database is a database specifically designed to store information about the structure of molecules and crystals. Crystals are solids having, in all three dimensions of space, a regularly repeating arrangement of atoms, ions, or molecules. They are characterized by symmetry, morphology, and directionally dependent physical ...
Mercury is a freeware developed by the Cambridge Crystallographic Data Centre, originally designed as a crystal structure visualization tool. Mercury helps three dimensional visualization of crystal structure and assists in drawing and analysis of crystal packing and intermolecular interactions.
The distortion free energy density is a quantity that describes the increase in the free energy density of a liquid crystal caused by distortions from its uniformly aligned configuration. It also commonly goes by the name Frank free energy density named after Frederick Charles Frank.
Single-player. Cris Tales (stylized as CrisTales) is a role-playing video game developed by Colombian indie game studios Dreams Uncorporated and Syck, and published by Modus Games. It was released for Google Stadia, Microsoft Windows, Nintendo Switch, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X/S on July 20, 2021.
In the Cambridge Structural Database of small-molecule structures, more than 95% of the 500,000+ crystals have an R-factor lower than 0.15, and 9.5% have an R-factor lower than 0.03. Crystallographers also use the Free R-Factor ( R F r e e {\displaystyle R_{Free}} ) [3] to assess possible overmodeling of the data.
