Sexual reproduction predominates among eukaryotic organisms on our planet. While debate
continues over why this should be so, burgeoning genomic and functional information now …

PURPOSE: To evaluate whether preoperative chemotherapy (PCT) could improve survival
in resectable stage I (except T1N0), II, and IIIA non–small-cell lung cancer (NSCLC). …

Antenna patterns with ultra-low sidelobes have been obtained for an experimental receiving
array designed with time-modulated slot radiators. The technique utilizes on-off RF switches …

Here we probe the relationships between assembly of the synaptonemal complex (SC) and
progression of recombination between homologous chromosomes during Caenorhabditis …

Analysis of Caenorhabditis elegans syp-1 mutants reveals that both synapsis-dependent
and -independent mechanisms contribute to stable, productive alignment of homologous …

Germline maintenance in the nematode C. elegans requires global repressive mechanisms
that involve chromatin organization. During meiosis, the X chromosome in both sexes …

We have investigated the role of pairing centers (PCs), cis-acting sites required for accurate
segregation of homologous chromosomes during meiosis in C. elegans. We find that these …

Organisms that reproduce sexually must reduce their chromosome number by half during
meiosis to generate haploid gametes. To achieve this reduction in ploidy, organisms must …

Transfusions are more common in premature infants with approximately 40% of low birth
weight infants and up to 90% of extremely low birth weight infants requiring red blood cell …

We report experimental values for the nonlinear optical coefficients of AlGaAs, in the half-band-gap
spectral region. The dispersion of the nonlinear refractive-index coefficient, n/sub 2/, …
