Counting Orbits Under Kreweras Complementation
The Kreweras complementation map is an anti-isomorphism on the lattice of noncrossing partitions. We consider an analogous operation for plane trees motivated by the molecular biology problem of RNA folding. In this context, we explicitly count the orbits of Kreweras’ map according to their length as the number of appropriate symmetry classes of trees in the plane. These new enumeration results...
متن کاملLarge Sophie Germain primes
If P is a prime and 2P+1 is also prime, then P is a Sophie Germain prime. In this article several new Sophie Germain primes are reported, which are the largest known at this time. The search method and the expected search times are discussed.
متن کاملJean St. Germain, M.S.
It is with great sadness that we share that Jean St. Germain, our colleague, friend, and integral member of the Medical Physics Department at Memorial Sloan Kettering Cancer Center (MSKCC) for over 50 yr, passed away on December 7, 2017. She died peacefully and was with her brother, Amos, at the time. Following completion of graduate study at Rutgers University and a fellowship at Brookhaven Na...

متن کاملSGCM: The Sophie Germain Counter Mode
Sophie Germain Counter Mode (SGCM) is an authenticated encryption mode of operation, to be used with 128-bit block ciphers such as AES. SGCM is a variant of the NIST standardized Galois / Counter Mode (GCM) which has been found to be susceptible to weak key / short cycle forgery attacks. The GCM attacks are made possible by its extremely smooth-order multiplicative group which splits into 512 s...
