Lyra2 is a (PHS) that can also work as a key derivation function (KDF). It received a special recognition during the Password Hashing Competition in July 2015., which was won by Argon2. Besides being used for its original purposes, it is also in the core of proof-of-work algorithms such as Lyra2REv2, adopted by Vertcoin, MonaCoin, among other cryptocurrenciesLyra2 was designed by Marcos A. Simplicio Jr., Leonardo C. Almeida, Ewerton R. Andrade, Paulo C. F. dos Santos, and Paulo S. L. M. Barreto from Escola Politécnica da Universidade de São Paulo. It is an improvement over Lyra, previously proposed by the same authors. Lyra2 preserves the security, efficiency and flexibility of its predecessor, including: (1) the ability to configure the desired amount of memory, processing time and parallelism to be used by the algorithm; and (2) the capacity of providing a high memory usage with a processing time similar to that obtained with scrypt. In addition, it brings the following improvements when compared to its predecessor: * it allows a higher security level against attack venues involving time-memory trade-offs * it allows legitimate users to benefit more effectively from the parallelism capabilities of their own platforms * it includes tweaks for increasing the costs involved in the construction of dedicated hardware to attack the algorithm * it balances resistance against side-channel threats and attacks relying on cheaper (and, hence, slower) storage devices * Lyra2 is released under public domain, and provides two main extensions: * Lyra2-δ, gives the user better control over the algorithm's bandwidth usage * Lyra2p, takes advantage of parallelism capabilities on the legitimate user's platform This algorithm enables parameterization in terms of: * execution time (time cost ) * memory required (number of rows , and number of columns ) * degree of parallelism (number of threads ) * underlying permutation function (can be seen as the main cryptographic primitive) * number of blocks used by the underlying permutation function (bitrate) * number of rounds performed for the underlying permutation function * number of bits to be used in rotations * output length (Wikipedia).
The High-Luminosity LHC project takes shape at CERN's Point 1

Why is SN2 a one-step reaction and SN1 a two-step reaction! Argh! Just listen to Dave, he'll tell you about the mechanism, intermediate, and lack of stereospecificity for the SN1 reaction. Look out for racemic mixtures! Watch the whole Organic Chemistry playlist: http://bit.ly/ProfDaveOrg

We've been hearing about DNA since the third grade, and we all know that it's a double helix with little ladder rungs. But now we are ready to understand this molecule on a more fundamental level, which will enable to us to understand how this molecule can serve as the genetic code. Let's

More light for the LHC: meet HiLumi LHC project | CERN
What is HiLumi? The High Luminosity LHC (HL-LHC) is an upgrade of the LHC to achieve instantaneous luminosities a factor of five larger than the LHC nominal value, thereby enabling the experiments to enlarge their data sample by one order of magnitude compared with the LHC baseline program
