Abstract PISTILLATA ( PI ), as a member of MADS-box transcription factor, plays an important role in petal and stamen specification in Arabidopsis . However, little is known about PI-like gene in citrus. To understand the molecular mechanism of PI during the developmental process of citrus...

The topological structure of a dynamical network plays a pivotal part in its properties, dynamics and control. Thus, understanding and modeling the structure of a network will lead to a better knowledge of its evolutionary mechanisms and to a better cottoning on its dynamical and functional...

The large leakage accidents of heavy metals from industrial facilities pose a serious environmental problem; however, not enough studies have been conducted to assess the long-term ecological risk associated with such accidents. This study assessed the alterations in the bacterial community of...

Using UK open market repurchases, we reject the market underreaction hypothesis and the market overreaction hypothesis proposed by (Ikenberry, Lakonishok and Vermaelen 1995) and (Peyer and Vermaelen 2009), respectively. The evidence supports that the UK market reacts slowly to actual repurchases...

We examine long run firm performance following UK open market share repurchases announced between 1999 and 2004. We find the long run abnormal share performance among UK repurchasing firms after the initial announcement. The mean two-year abnormal buy-and-hold returns of small firms and value...
