PIWI-interacting RNAs (piRNAs) silence transposable elements in animal germ cells. In Drosophila ovaries, piRNAs are produced by two distinct pathways: the "ping-pong" amplification cycle that operates in germ cells and a ping-pong-independent pathway termed the primary pathway that mainly operates in somatic cells. AGO3, one of three PIWI proteins in flies, is involved in the ping-pong cycle i...

The current methods of communication using steganography techniques involve the use of carrier files including network protocols. The current study presents a new method of communication using steganography techniques available today, the carrier being a ping. The study will also present the most effective ways of prevention against this form of secret communication. Key-Words: steganography, i...

Distributed denial of service attack (DDoS) is an attempt by malicious hosts to overload website, network, e-mail servers, applications, network resources, bandwidth, etc. Globally DDoS attacks affected four out of ten organizations (around 41 %) over the past few years. Challenges involved in taking counter measures against DDoS attacks are network infrastructure, identifying legitimate traffi...

1. Introduction. In the early hours of March 8, 2014, a Malaysia Airlines Boe-ing 777 disappeared en route from Kuala Lumpur to Beijing with 239 people on board [14]. At the time of writing this article there has been no confirmation of any debris from the aircraft and no survivors have been found. 1 If the crash site is not discovered, this tragedy may become one of the great aviation mysterie...

We examine the influence of dendritic load on the firing dynamics of a spatially extended leaky integrate-and-fire (LIF) neuron that explicitly includes spiking dynamics. We obtain an exact analytical solution for this model and use it to derive a return map that completely captures the dynamics of the system. Using the map, we find that dendritic properties can significantly change the firing ...
