(α,α-dimethyl)glycyl (dmg) PNAs

The design and facile synthesis of sterically constrained new analogs of PNA having gem-dimethyl substitutions on glycine (dmg-PNA-T) is presented. The PNA oligomers [aminoethyl dimethylglycyl (aedmg) and aminopropyl dimethylglycyl (apdmg)] synthesized from the monomers 6 and 12) effected remarkable stabilization of homothyminePNA(2):homoadenine DNA/RNA triplexes and mixed base sequence duplexe...

Vibrational, conformational and electronic structure investigations of α,α'-dibromo-o-xylene, α,α'-dibromo-m-xylene and α,α'-dibromo-p-xylene.

The Fourier transform infrared (FTIR) and FT-Raman spectra of α,α'-dibromo-o-xylene (DBOX), α,α'-dibromo-m-xylene (DBMX) and α,α'-dibromo-p-xylene (DBPX) of the configuration BrCH(2)C(6)H(4)CH(2)Br have been recorded in the range 4000-400 and 4000-100 cm(-1), respectively. The conformational analysis of these compounds was performed. The complete vibrational assignment and analysis of the funda...

On α-decodability and α-likelihood decoder

Generalizing the maximum and the average error criteria for channel coding, we introduce the α-decodability, defined as the α-norm of the probabilities of correctly decoding the messages. Several aspects, such as the exponent, the existence of a strong Fano’s inequality, and the achievability of the channel capacity by random coding are investigated, and it is revealed that α “ 0 (corresponding...

Order-k α-hulls and α-shapes

We introduce order-k α-hulls and αshapes — generalizations of α-hulls and α-shapes. Being also a generalization of k-hull (known in statistics as “k-depth contour”), order-k α-hull provides a link between shape reconstruction and statistical depth. As a generalization of α-hull, order-k α-hull gives a robust shape estimation by ignoring locally up to k outliers in a point set. Order-k α-shape p...
