Sleep promotes memory consolidation in humans and many other species, but the physiological and anatomical relationships between sleep and memory remain unclear. Here, we show the dorsal paired medial (DPM) neurons, which are required for memory consolidation in Drosophila, are sleep-promoting inhibitory neurons. DPMs increase sleep via release of GABA onto wake-promoting mushroom body (MB) α'/...

In this paper, a reversible data hiding scheme based on two dimensional difference histogram modification is proposed. We adopted difference-pairmapping (DPM) strategy. A sequence of pairs of difference values is calculated by taking each pixel-pair and its surroundings. Then, a two-dimensional difference-histogram is produced by counting the frequency of the resulting difference pairs. Then, a...

Although aging is known to impair intermediate-term memory in Drosophila, its effect on protein-synthesis-dependent long-term memory (LTM) is unknown. We show here that LTM is impaired with age, not due to functional defects in synaptic output of mushroom body (MB) neurons, but due to connectivity defects of dorsal paired medial (DPM) neurons with their postsynaptic MB neurons. GFP reconstituti...

The rising threat of cyber attacks, especially distributed denial-of-service (DDoS), makes the IP Traceback problem very relevant to today’s Internet security. IP Traceback is one of the security problems associated with identifying the source of the attack packets. This work presents a novel approach to IP Traceback Deterministic Packet Marking (DPM). The proposed approach is scalable, simple ...

This paper discusses several of the SOC design issues pertaining to dynamic voltage and frequency scalable systems, and how these issues were resolved in the IBM PowerPC 405LP processor. We also introduce DPM, a novel architecture for policy-guided dynamic power management. We illustrate the utility of DPM by its ability to implement several classes of power management strategies and demonstrat...
