Genetic and molecular analyses of patterning of the Drosophila embryo have shown that the process of segmentation of the head is fundamentally different from the process of segmentation of the trunk. The cephalic furrow (CF), one of the first morphological manifestations of the patterning process, forms at the juxtaposition of these two patterning systems. We report here that the initial step i...

In this paper, we study a K-user fading multiple access channel (F-MAC), with and without an eavesdropper (Eve). In the system without Eve, we assume that each user knows only its own channel gain and is completely ignorant about the other users’ channel state. The legitimate receiver sends a short acknowledgement message Acknowledge (ACK) if the message is correctly decoded and a No Acknowledg...

Three parties, Alice, Bob and Eve, know the sequences of ran-generated by a discrete memoryless source according to some probability distribution P XY Z. Motivated by Wyner's and Csiszz ar and KK orner's pioneering definition of, and work on, the secrecy capacity of a broadcast channel, the secret key rate of P XY Z was deened by Maurer as the maximal rate M=N at which Alice and Bob can generat...

Individual neurons adopt and maintain defined morphological and physiological phenotypes as a result of the expression of specific combinations of transcription factors. In particular, homeodomain-containing transcription factors play key roles in determining neuronal subtype identity in flies and vertebrates. dbx belongs to the highly divergent H2.0 family of homeobox genes. In vertebrates, Db...

The Virgin Mary and Eve constitute two opposite sexual poles in the way Christian discourse has approached women since the time of the church fathers. This stems from a predicament faced by the human male throughout hominid evolution, namely, paternal uncertainty. Because the male is potentially always at risk of unwittingly raising the offspring of another male, two (often complementary) male ...

It has been most interesting to listen to the initial part of this conference, particularly references to the continuing viability of the check clearing system, and views as to the social cost, economic justification and impact on the public interest of electronic alternatives. It has made me most grateful to have a job whereby I can meet with the rest of the gods here on Mount Olympus to discu...

We investigated the hypothesis that several transcriptional repressors are necessary to set the boundaries of anterior pair-rule stripes in Drosophila. Specifically, we tested whether Tailless (Tll) is part of a repression mechanism that correctly sets the anterior boundaries of hairy 1 (h 1) and even-skipped 1 (eve 1) stripes. Single mutant tll embryos displayed subtle deviations from the norm...
