Chinese species of egg-parasitoids of the genera Oxyscelio Kieffer, Heptascelio Kieffer and Platyscelio Kieffer (Hymenoptera: Platygastridae s.l., Scelioninae)

To date, the known Chinese fauna of egg-parasitoids of the genus Oxyscelio Kieffer encompasses two species from the mainland - Oxysceliodoumao Burks and Oxyscelionubbin Burks. Here we record eighteen species of Oxyscelio from collections in mainland China: Oxyscelioarvi Burks, Oxyscelioceylonensis (Dodd), Oxyscelioconvergens Burks, Oxysceliocordis Burks, Oxysceliocrebritas Burks, Oxysceliocucul...

Distribution of Lee-Yang zeros and Griffiths singularities in the ±J model of spin glasses

We investigate the distribution of zeros of the partition function of the twoand three-dimensional symmetric ±J Ising spin glasses on the complex field plane. We use the method to analytically implement the idea of numerical transfer matrix which provides us with the exact expression of the partition function as a polynomial of fugacity. The results show that zeros are distributed in a wide reg...

4-Hydroxynonenal (4-HNE) is a peroxidation product of ˆ-6-poly-unsaturated fatty acids and exerts growth modifying as well as cytotoxic activities. This aldehyde component of oxidized lipid is increased during the aging process. In this study, to characterize the potential role of the lipid peroxidation product in aging, we studied the effects of 4-HNE on cell proliferation and activation of ce...

I Over the last decade or so, much has been written about the new "science of complexity". From journalistic hyperbole to cutting edge research, it is widely assumed that the science of complexity has indeed discovered something new, that is worthy of the attention of scientists and philosophers alike. But what? An overarching principle that connects the study of complex systems across the phys...
