Prohibitin is an evolutionary conserved protein that is associated with cellular differentiation, atresia, and luteolysis in the rat ovary. However, the specific cellular location and function of prohibitin in ovarian cells has not been clearly elucidated. To characterize the expression of prohibitin during cell proliferation, differentiation, and cell death, we have successfully established a ...

ABSTRACT Most barley cultivars are resistant to stripe rust of wheat that is caused by Puccinia striiformis f. sp. tritici. The barley cv. Steptoe is susceptible to all identified races of P. striiformis f. sp. hordei (PSH), the barley stripe rust pathogen, but is resistant to most P. striiformis f. sp. tritici races. To determine inheritance of the Steptoe resistance to P. striiformis f. sp. t...

This paper proposes a new paradigm, referred to as Recurrent Genetic Algorithms (RGA), to sustain Genetic Algorithm (GA) evolvability and effectively improves its ability to find superior solutions. RGA attempts to continually recover evolvability loss caused by the canonical GA iteration process. It borrows the term Recurrent from the taxonomy of Neural Networks (NN), in which a Recurrent NN (...

Plasma plumes resulting from Nd:YAG laser ablation of copper and Fecralloy (Fe 72.8%, Cr 22%, Al 5%, Zr trace, Y trace) have been analysed simultaneously with Laser-Induced Breakdown Spectroscopy (LIBS) and Laser Ablation Mass Spectrometry (LAMS). A commercially available Residual Gas Analyser (RGA) was employed to perform mass spectrometric analysis of the neutral and ionic species created dur...

The Relative Gain Array (RGA) provides a quantitative comparison of interactions between control loops. It shows steady state interactions between control loops. The thermodynamic concept of exergy can be used to analyse a process in terms of its efficiency. The Relative Exergy Array (REA) that measures both the relative exergetic efficiency and controllability of a process has been proposed (2...
