Proteomic and Transcriptomic Analysis for Identification of Endosymbiotic Bacteria Associated with BYDV Transmission Efficiency by Sitobion miscanthi [PDF]

open access: yesPlants, 2022
Sitobion miscanthi, an important viral vector of barley yellow dwarf virus (BYDV), is also symbiotically associated with endosymbionts, but little is known about the interactions between endosymbionts, aphid and BYDV.

Transmission efficiency drives host-microbe associations. [PDF]

open access: yesProc Biol Sci, 2020
Abstract Sequencing technologies have fueled a rapid rise in descriptions of microbial communities associated with hosts, but what is often harder to ascertain is their evolutionary significance. Here we review the existing literature on the role of vertical (VT), horizontal (HT), environmental acquisition, and mixed modes (MMT) of ...

On transmission efficiency of quantum modulations [PDF]

open access: yesQuantum Studies: Mathematics and Foundations, 2019
In quantum information theory, it is important to find modulations with low information loss for noisy channels. In this paper, using the quantum dynamical entropy and the quantum dynamical mutual entropy, we investigate the transmission efficiency of two quantum modulators through attenuation channels.

On Adaptive Energy-Efficient Transmission in WSNs [PDF]

open access: yesInternational Journal of Distributed Sensor Networks, 2013
One of the major challenges in design of wireless sensor networks (WSNs) is to reduce energy consumption of sensor nodes to prolong lifetime of finite capacity batteries. In this paper, we propose energy-efficient adaptive scheme for transmission (EAST) in WSNs. EAST is an IEEE 802.15.4 standard compliant.
