The computational Diffie–Hellman (CDH) assumption is a computational hardness assumption about the Diffie–Hellman problem. [1] The CDH assumption involves the problem of computing the discrete logarithm in cyclic groups. The CDH problem illustrates the attack of an eavesdropper in the Diffie–Hellman key exchange [2] protocol to obtain the ...
Decisional Diffie–Hellman assumption. The decisional Diffie–Hellman (DDH) assumption is a computational hardness assumption about a certain problem involving discrete logarithms in cyclic groups. It is used as the basis to prove the security of many cryptographic protocols, most notably the ElGamal and Cramer–Shoup cryptosystems .
CDH Investments ( CDH, 鼎晖投资基金管理公司) is a major Chinese alternative asset management firm based in Beijing, China. It specializes in private equity, venture capital and credit products. [2] CDH invests across a range of sectors and regions. As of March 2015, CDH manages over RMB 100 billion of investor capital across its ...
Cadherin-1 or Epithelial cadherin (E-cadherin), (not to be confused with the APC/C activator protein CDH1) is a protein that in humans is encoded by the CDH1 gene. [5] Mutations are correlated with gastric, breast, colorectal, thyroid, and ovarian cancers. CDH1 has also been designated as CD324 ( cluster of differentiation 324).
Congenital diaphragmatic hernia ( CDH) is a birth defect of the diaphragm. The most common type of CDH is a Bochdalek hernia; other types include Morgagni hernia, diaphragm eventration and central tendon defects of the diaphragm. Malformation of the diaphragm allows the abdominal organs to push into the chest cavity, hindering proper lung ...
T-cadherin, also known as cadherin 13, H-cadherin (heart), and CDH13, is a unique member of the cadherin superfamily of proteins because it lacks the transmembrane and cytoplasmic domains common to all other cadherins and is instead anchored to the cell's plasma membrane by the GPI anchor. Unlike classical cadherins, which are necessary for ...
List of chemical elements. 118 chemical elements have been identified and named officially by IUPAC. A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z ). [1]
Story. The story follows a group of Czechoslovak Legion soldiers during the Russian Civil War and roughly aligns with the Revolt of the Czechoslovak Legion.Following World War I, Czechoslovak soldiers are trapped in Russia and have to set on a journey through Siberia on the Trans-Siberian Railway to get Home.
