Host Interception of Bacterial Communication Signals

Optimal Interception and Direction Finding of Signals in a Mobile Communication Network with Directive Antennas~

For hostile communication environments, noncentralized mobile communication network with directive/adaptive antennas and Global Positioning System (GPS) has been proposed for the purpose of minimizing the radio exposure and making it difficult for an interceptor to detect the signals. This paper investigates the interceptor’s search for the direction-of-arrival (DOA) of the transmitting signal ...

Epigenetic Modifications of Host Genes Induced by Bacterial Infection

Introduction: Epigenetic mechanisms regulate expression of the genome to generate various cell types during development or coordinate cellular responses to external stimulus. While epigenetics is of fundamental importance in eukaryotes, it plays a different role in bacteria. This article uncovers the most important recent data on how bacteria can alter epigenetic marks and can also contribute t...

Transcript analysis of some defense genes of tomato in response to host and non-host bacterial pathogens

The transcript levels of six defense genes including pathogenesis-related gene 1 (PR-1), pathogenesis-related gene 2 (PR-2), pathogenesis-related gene 5 (PR-5), lipoxygenase (LOX), phenylalanine ammonia-lyase (PAL) and catalase (CAT) were investigated in tomato plants inoculated with Xanthomonas axonopodis pv. phaseoli as a non-host pathogen and X. euvesicatoria as a host pathogen. Activation o...

Translation-Invariant Modulation Spectrum with Application to Communication Signal Interception

In many signal processing applications, such as communications signal interception, the signal’s modulation type is unknown. Accurately identifying the modulation type is therefore a critical first step in monitoring or other use of the communication channel. Past work on automatic identification of modulation type has mostly focused on using a combination of short-term spectral features and au...
