Quantitative Modelling of Diffusion-driven Pattern Formation in microRNA-regulated Gene Expression

no code implementations18 Jul 2023 Priya Chakraborty, Sayantari Ghosh

MicroRNAs are extensively known for post-transcriptional gene regulation and pattern formation in the embryonic developmental stage.

Spatio-temporal Pattern Formation due to Host-Circuit Interplay in Gene Expression Dynamics

no code implementations12 Oct 2022 Priya Chakraborty, Ushasi Roy, Mohit K. Jolly, Sayantari Ghosh

Biological systems are majorly dependent on their property of bistability in order to exhibit nongenetic heterogeneity in terms of cellular morphology and physiology.

Resource competition in Three-gene-motif & Emergence of Feed-forward response: A Spatiotemporal Study

no code implementations28 Sep 2022 Priya Chakraborty, Ushasi Roy, Sayantari Ghosh

Feed-forward dynamics, which is well-known to have several important implications in nonlinear dynamical systems, frequently occurs in gene expression motifs, and has been well explored experimentally and mathematically.

Resource allocation determines alternate cell fate in Bistable Genetic Switch

no code implementations24 May 2022 Priya Chakraborty, Sayantari Ghosh

Limited availability of cellular resources for gene expression, like ribosomes, along with a variation of resource affinity, significantly modifies the system dynamics.

Emergent Regulatory Response and Shift of Half induction point under Resource Competition in Genetic circuits

no code implementations9 Dec 2021 Priya Chakraborty, Sayantari Ghosh

as resource from the host cell and in translation, ribosome, tRNA and other cellular resources are supplied to the operating circuit.

Attention W-Net: Improved Skip Connections for better Representations

no code implementations17 Oct 2021 Shikhar Mohan, Saumik Bhattacharya, Sayantari Ghosh

We propose Attention W-Net, a new U-Net based architecture for retinal vessel segmentation to address these problems.

Decoder Image Augmentation +2

Detection Of Concrete Cracks using Dual-channel Deep Convolutional Network

no code implementations22 Sep 2020 Babloo Kumar, Sayantari Ghosh

Due to cyclic loading and fatigue stress cracks are generated, which affect the safety of any civil infrastructure.

A Data-driven Understanding of COVID-19 Dynamics Using Sequential Genetic Algorithm Based Probabilistic Cellular Automata

no code implementations27 Aug 2020 Sayantari Ghosh, Saumik Bhattacharya

In this work, a probabilistic cellular automata based method has been employed to model the infection dynamics for a significant number of different countries.

Emergent Correlations in Gene Expression Dynamics as Footprints of Resource Competition

no code implementations16 Jul 2020 Priya Chakraborty, Sayantari Ghosh

In this paper, we employ mathematical modelling and in-silico experiments to identify the sources of resource trade-off and to quantify its impact on the function of a genetic circuit, keeping our focus on regulation of immediate downstream proteins.
