Signal Processing in the Retina: Interpretable Graph Classifier to Predict Ganglion Cell Responses

no code implementations3 Jan 2024 Yasaman Parhizkar, Gene Cheung, Andrew W. Eckford

To extract knowledge from the cell firings, in this paper we learn an interpretable graph-based classifier from data to predict the firings of ganglion cells in response to visual stimuli.

Localization of a Passive Source with a Sensor Network based Experimental Molecular Communication Platform

no code implementations28 Nov 2023 Fatih Gulec, Damla Yagmur Koda, Baris Atakan, Andrew W. Eckford

In a practical molecular communication scenario such as monitoring air pollutants released from an unknown source, it is essential to estimate the location of the molecular transmitter (TX).

Molecular Communication for Quorum Sensing Inspired Cooperative Drug Delivery

no code implementations15 Feb 2023 Yuting Fang, Stuart T. Johnston, Matt Faria, Xinyu Huang, Andrew W. Eckford, Jamie Evans

Our results show that the activation probability at the B-NM increases as this B-NM is located closer to the center of the B-NM population and the aggregate absorption rate of the drug molecules non-linearly increases as the population density increases.

A Stochastic Biofilm Disruption Model based on Quorum Sensing Mimickers

no code implementations30 Jan 2023 Fatih Gulec, Andrew W. Eckford

Quorum sensing (QS) mimickers can be used as an effective tool to disrupt biofilms which consist of communicating bacteria and extracellular polymeric substances.

Stochastic Modeling of Biofilm Formation with Bacterial Quorum Sensing

no code implementations12 Dec 2022 Fatih Gulec, Andrew W. Eckford

In this paper, a stochastic model is proposed for biofilm formation, using bacterial quorum sensing (QS).

Low Complexity First: Duration-Centric ISI Mitigation in Molecular Communication via Diffusion

no code implementations19 Jul 2022 Xuan Chen, Fei Ji, Miaowen Wen, Yu Huang, Yuankun Tang, Andrew W. Eckford

In this paper, we propose a novel inter-symbol interference (ISI) mitigation scheme for molecular communication via diffusion (MCvD) systems with the optimal detection interval.

Selectivity of Protein Interactions Stimulated by Terahertz Signals

no code implementations4 Jul 2022 Hadeel Elayan, Andrew W. Eckford, Raviraj Adve

To establish that, we formulate a selectivity metric that quantifies the system performance and captures the capability of the nanoantenna to induce a conformational change in the desired protein molecule/population.

Minimal informational requirements for fitness

no code implementations3 Dec 2021 Alexander S. Moffett, Andrew W. Eckford

The existing concept of the "fitness value of information" provides a theoretical upper bound on the fitness advantage of using information concerning a fluctuating environment.

A factor graph EM algorithm for inference of kinetic microstates from patch clamp measurements

no code implementations17 Jun 2021 Alexander S. Moffett, Guiying Cui, Peter J. Thomas, William D. Hunt, Nael A. McCarty, Ryan S. Westafer, Andrew W. Eckford

We derive a factor graph EM (FGEM) algorithm, a technique that permits combined parameter estimation and statistical inference, to determine hidden kinetic microstates from patch clamp measurements.

Modelling the Role of Inter-cellular Communication in Modulating Photosynthesis in Plants

no code implementations29 Mar 2021 Hamdan Awan, Raviraj S. Adve, Nigel Wallbridge, Carrol Plummer, Andrew W. Eckford

In this paper we show how inter-cellular molecular communication may change the overall levels of photosynthesis in plants.

no code implementations2 Sep 2020 Hadeel Elayan, Andrew W. Eckford, Raviraj Adve

In this work, we present a paradigm bridging electromagnetic (EM) and molecular communication through a stimuli-responsive intra-body model.

Linear Noise Approximation of Intensity-Driven Signal Transduction Channels

no code implementations28 Aug 2019 Gregory R. Hessler, Andrew W. Eckford, Peter J. Thomas

Biochemical signal transduction, a form of molecular communication, can be modeled using graphical Markov channels with input-modulated transition rates.

Expected Density of Cooperative Bacteria in a 2D Quorum Sensing Based Molecular Communication System

no code implementations1 Dec 2018 Yuting Fang, Adam Noel, Andrew W. Eckford, Nan Yang

The number of molecules observed at each randomly-distributed bacterium is first derived by characterizing the diffusion and degradation of signaling molecules within the population.
