New Subclass Framework and Concrete Examples of Strongly Asymmetric Public Key Agreement

open access: yesApplied Sciences, 2021
Strongly asymmetric public key agreement (SAPKA) is a class of key exchange between Alice and Bob that was introduced in 2011. The greatest difference from the standard PKA algorithms is that Bob constructs multiple public keys and Alice uses one of ...

On Asymmetric Hypergraphs

open access: yes, 2021
In this paper, we prove that for any $k\ge 3$, there exist infinitely many minimal asymmetric $k$-uniform hypergraphs. This is in a striking contrast to $k=2$, where it has been proved recently that there are exactly $18$ minimal asymmetric graphs. We also determine, for every $k\ge 1$, the minimum size of an asymmetric $k$-uniform hypergraph.

MCM-41-supported L-phenylalaninol as a chiral heterogeneous ligand in the enantioselective Kharasch-Sosnovsky reaction

open access: yesResults in Chemistry
In this study, L-phenylalaninol, synthesized from the reduction of naturally occurring L-phenylalanine, was immobilized on MCM-41. The resulting heterogeneous ligand was comprehensively characterized using various spectroscopic techniques, such as FT-IR,
