UAV positioning for throughput maximization

open access: yesEURASIP Journal on Wireless Communications and Networking, 2018
The throughput of a communication system depends on the offered traffic load and the available capacity to support that load. When an unmanned aerial verhicle (UAV) is responsible for providing the communication service to users within its transmission ...

Electrophysiological In Vitro Study of Long‐Range Signal Transmission by Astrocytic Networks

open access: yesAdvanced Science, 2023
Astrocytes are diverse brain cells that form large networks communicating via gap junctions and chemical transmitters. Despite recent advances, the functions of astrocytic networks in information processing in the brain are not fully understood.

Reduction in mobility and COVID-19 transmission

open access: yesNature Communications, 2021
In response to the COVID-19 pandemic, countries have sought to control SARS-CoV-2 transmission by restricting population movement through social distancing interventions, thus reducing the number of contacts.

Modelling transmission and control of the COVID-19 pandemic in Australia [PDF]

open access: yesNature Communications, 2020
There is a continuing debate on relative benefits of various mitigation and suppression strategies aimed to control the spread of COVID-19. Here we report the results of agent-based modelling using a fine-grained computational simulation of the ongoing ...

An energy window study of light transmission-disorder relationship in 1D photonic structures

open access: yes, 2018
While the light transmission of photonic crystals is characterized by the photonic band gap, the one of disordered photonic structures is typified by a multiplicity of transmission depths.

The airborne lifetime of small speech droplets and their potential importance in SARS-CoV-2 transmission

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2020
Speech droplets generated by asymptomatic carriers of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are increasingly considered to be a likely mode of disease transmission. Highly sensitive laser light scattering observations have revealed

Long-Range Response to Transmission Line Disturbances in DC Electricity Grids

open access: yes, 2014
We consider a DC electricity grid composed of transmission lines connecting power generators and consumers at its nodes. The DC grid is described by nonlinear equations derived from Kirchhoff's law.

Empirical modelling and simulation of transmission loss between wireless sensor nodes in gas turbine engines [PDF]

open access: yes, 2009
Transmission loss measurements between a grid of hypothetical WSN node locations on the surface of a gas turbine engine are reported for eight frequencies at 1 GHz intervals in the frequency range 3.0 to 11.0 GHz.
