Three ecdysteroid 7,9(11)-dien-7-ones (dacryhainansterone, 25-hydroxydacryhainansterone and kaladasterone) were prepared by dehydration of the corresponding 11a-hydroxy ecdysteroids (ajugasterone C, turkesterone and muristerone A, respectively). The biological activities of the dienones in the Drosophila melanogaster B(II) cell bioassay, which reflect the affinity for the ecdysteroid receptor c...

An efficient and greener protocol for the synthesis of 12-aryl-8,9,10,12-tetrahydrobenzo[a]xanthen-11-one using tetradecyltrimethylammonium bromide (TTAB) at room temperature in water is described.

In this paper, we analyze complemented group Cellular Automata (CA) derived from Linear Hybrid Group CA with rules 60, 102 and 204. We analyze some properties of the CA. And we give rule vectors which determine the state transition of the CA dividing the entire state space into smaller spaces of equal lengths, and find conditions for the complement vectors corresponding to the rule vectors. And...

This paper presents a novel multi-Gb/s multi-mode LDPC decoder architecture and efficient design techniques for gigabit wireless communications. An efficient dynamic and fixed column-shifting scheme is presented for multi-mode architectures. A novel low-complexity local switch is proposed to implement the dynamic and fixed column-shifting scheme. Furthermore, an efficient quantization method an...

The plant family Rutaceae is known [1, 2] to be a prolific source of furoquinoline and pyranoquinoline alkaloids. Along with them acridine alka­ loids [3, 4] have also been isolated from several members of the same plant family. Recently furanfused acridine systems such as 1 l-methylfuro(2,3-c)acridan-6(l lH)one (1) have also been reported [5-7] to occur in some rutaceous plants. Typical exampl...

The sequential and indeterminate behavior of an end-around-carry (EAC) adder is examined. This behavior is commonly overlooked in the literature. Design modifications to impose determinism are provided. These modifications also eliminate the troublesome negative zero found in the one's complement number system.
