Asymmetric division of neural stem cells is a fundamental strategy to balance their self-renewal and differentiation. It is long thought that microtubules are not essential for cell polarity in asymmetrically dividing Drosophila melanogaster neuroblasts (NBs; neural stem cells). Here, we show that Drosophila ADP ribosylation factor like-2 (Arl2) and Msps, a(More)
In this paper, we investigate a joint scheduling and transmitting scheme in cognitive radio networks. Three phases are considered in the proposed scheme(named scheme 1): l)in the first phase, JVt primary users(PUs) in the high-rate region are chosen to implement communication with primary base station (PBS); 2)in the second phase, PBS will support(More)
—Nowadays, cognitive radio technique has been acknowledged as a smart and potential method to improve the spectrum utilization. In this work, we investigate a cognitive radio communication scheme, where a number of cognitive users, each with multiple antennas, can share the spectrum with the primary user. To decrease the inter-user interference,(More)
A multi-functional polystyrene based adsorbent (NKU-9) with a unique mesoporous and a high surface area was prepared by suspension polymerization for removal of therapeutic toxins in blood purification. The adsorbent produced had an almost equal amount of mesopore distribution in the range from 2 to 50 nm. The adsorption of serum toxins with different(More)
