Carbon, Nitrogen, and Oxygen Abundances in Early B-Type Stars

Abstract: We report on a survey of the C, N, and O abundances in a sample of early B-type stars which was undertaken to test Lyubimkov's claim that CN-cycled material is mixed to the surfaces of these stars during their core hydrogen-burning phase. We have obtained equivalent widths of generally weak lines using high signal-to-noise Reticon spectra of 39 stars in four spectral regions. We have derived effective temperatures and gravities for these stars using Stromgren dereddened color indices and Hy line profiles through a comparison with colors and line profiles from Kurucz line-blanketed atmospheres

Noncovalent interactions with DNA: an overview.

Abstract: Over the last four decades, intense research has focused on the effects of small organic compounds that noncovalently bind to nucleic acids. These interactions have been shown to disrupt replication and/or transcription culminating in cellular death. Accordingly, DNA binding compounds have potential applications as anti-cancer and anti-viral agents. This report provides an overview of the different DNA-binding modes with an emphasis on DNA groove specificity for the groove-binding and intercalation modes. While most DNA-interacting agents selectively bind to DNA by either groove binding or intercalation, some compounds can exhibit both binding modes. The binding mode with the most favorable free energy for complex formation depends on the DNA sequence and structural features of the bound ligand.

Of Shepherds, Sheep, and the Cross-autocorrelations in Equity Returns

Abstract: We present an economic mechanism and supportive empirical evidence for the transmission of information between equity securities first documented by Lo and MacKinlay (1990). It is argued that the past returns on stocks held by informed institutional traders will be positively correlated with the contemporaneous returns on stocks held by noninstitutional uninformed traders. Evidence consistent with this hypothesis is then presented. We document that the returns on the portfolio of stocks with the highest level of institutional ownership lead the returns of portfolios of stocks with lower levels of institutional ownership. This effect persists even after firm size is controlled for and is apparent at longer lags than the size-related lag effect documented in Lo and MacKinlay (1990).
