Beilstein Journal of Organic Chemistry, 2013 In this work, we introduce a new class of halodiazocarbonyl compounds, α-halodiazoacetamides, which through a metal-free, ambient-temperature thermolysis perform intramolecular C–H insertions to produce α-halo-β-lactams.

Predicting B cell receptor substitution profiles using public repertoire data. [PDF]
PLoS Computational Biology, 2018 B cells develop high affinity receptors during the course of affinity maturation, a cyclic process of mutation and selection. At the end of affinity maturation, a number of cells sharing the same ancestor (i.e.

Substitution-closed pattern classes [PDF]
, 2011 The substitution closure of a pattern class is the class of all permutations obtained by repeated substitution. The principal pattern classes (those defined by a single restriction) whose substitution closure can be defined by a finite number of ...

Quasi-cyclic Generalized LDPC codes with low error floors [PDF]
, 2008 In this paper, a novel methodology for designing structured generalized LDPC (G-LDPC) codes is presented. The proposed design results in quasi-cyclic G-LDPC codes for which efficient encoding is feasible through shift-register-based circuits.
