Reversible Watermarking is the technique of embedding secret messages into a cover image and recovering both the embedded secret message and the cover image without any distortion. One of the high quality and popular reversible data hiding methods is Difference Expansion method. In this paper, Difference Pair Mapping (DPM) method is used to embed the message into the cover image. The DPM method...

Clustering multi-dense large scale high dimensional numeric datasets is a challenging task duo to high time complexity of most clustering algorithms. Nowadays, data collection tools produce a large amount of data. So, fast algorithms are vital requirement for clustering such data. In this paper, a fast clustering algorithm, called Dimension-based Partitioning and Merging (DPM), is proposed. In ...

Data Matrix is a two-dimensional matrix code which has many advantages like as large information density, high capacity, and small size and so on. It is widely used in industrial automation, logistics, transportation and other fields. A two-dimensional barcode includes printing and DPM barcodes, which depending on the differences of the application at backgrounds of the two-dimensional barcode....

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 ...
