We propose and experimentally demonstrate a distance-adaptive bandwidth allocation scheme to realize high-capacity long-reach orthogonal frequency division multiple access passive optical network (OFDMA PON) with cost-effective electro-absorption modulator (EAM). In our scheme, the subcarriers in downstream OFDM signal are properly allocated to the optical network units (ONUs) with different fi...

This paper presents the procedure of the syntactic annotation of the National Corpus of Polish. Syntactic annotation consists here of shallow parsing and manual post-editing of the results by annotators. The description concentrates on the delimitation of syntactic words and groups, as well as on problems encountered during the annotation process.

BACKGROUND Juvenile idiopathic arthritis (JIA) is strongly associated with the DR8-DQ4 haplotype. The genes encoding DR8 and DQ4 are in strong linkage disequilibrium (LD) and occur together on the same HLA haplotype in almost all patients and controls. Because of the strong LD it is not clear whether DR8, DQ4, or both, are primarily associated with JIA. OBJECTIVE To unveil the primary associa...
