+# Community Outreach
+
+The CONTROL-CORE project has tremendously benefitted from open-source. We have been a part of the Google Summer of Code (GSoC), via the Department of Biomedical Informatics, Emory University as the mentoring organization. DHGWorkflow (which is adopted as the _concore_ Editor) was developed by the GSoC 2021 contributor. For GSoC 2022, we have 2 contributors - one working on _concore_ Editor and the other one on the _concore_ itself.
+
+Please use the GitHub discussion forums for user-queries. For GSoC and similar open-source contributions, as well as for other real-time user queries, feel free to join the GSoC Emory BMI slack workspace using the link - http://bit.ly/emory-bmi and find the channel "concore."

-# _concore_
-CONTROL-CORE is a framework for closed-loop peripheral neuromodulation control systems. The CONTROL-CORE protocol, known as _concore_, allows modular simulation of controller and PM nodes to run on different operating systems, computing platforms, and programming languages. 
+# CONTROL-CORE: A Framework for Simulation and Design of Closed-Loop Peripheral Neuromodulation Control Systems
 
+[CONTROL-CORE](https://github.com/ControlCore-Project/) is a design and simulation framework for closed-loop peripheral neuromodulation control systems. At its center is _concore_, a lightweight protocol to simulate neuromodulation control systems. This repository consists of the implementation of _concore_ protocol and sample (demo and neuromodulation control systems) studies. In addition to its default standard Python implementation, _concore_ also supports developing studies in Matlab/Octave, Verilog, and C++. _concore_ also aims to support more language programs in the future.
 
-# Configuring _concore_
+# The CONTROL-CORE Framework
 
-concore is a lightweight Python-based protocol to simulate neuromodulation control systems. Installation instructions for concore can be found [here](https://control-core.readthedocs.io/en/latest/installation.html).
+The CONTROL-CORE framework consists of the below projects.
 
+* _concore_: The CONTROL-CORE protocol, known as _concore_, allows modular simulation of controller and PM nodes to run on different operating systems, computing platforms, and programming languages. [This repository](https://github.com/ControlCore-Project/concore/) consists of _concore_ source code. The _concore_ documentation can be found [here](https://control-core.readthedocs.io/en/latest/index.html). A _concore_ study can be developed from programs written in different languages. That means, _concore_ facilitates a seamless communication across codes developed in different languages that it supports, through its simple file-based data sharing between the programs.
 
-# Using _concore_
+* _concore_ Editor: This is the front-end for CONTROL-CORE. We forked [DHGWorkflow](https://github.com/ControlCore-Project/DHGWorkflow), a sibling project we developed, and extend it as the _concore_ Editor. 
 
-Usage instructions can be found [here](https://control-core.readthedocs.io/en/latest/usage.html).
+* _Mediator_: The [Mediator](https://github.com/ControlCore-Project/mediator) allows the CONTROL-CORE studies to be distributed and run, rather than having all the programs that construct a study to be run just from a centralized location. 
+
+* _concore-lite_: The [_concore-lite_](https://github.com/ControlCore-Project/concore-lite) repository consists of a simple example version of a _concore_ study. Please check out and run this, if you like to learn the _concore_ protocol without having to clone this large _concore_ repository.
+
+* documentation: The [source code repository](https://github.com/ControlCore-Project/documentation) of the ReadTheDocs documentation of CONTROL-CORE.
+
+
+# The _concore_ Protocol
+
+_concore_ enables composing studies from programs developed in different languages. Currently supported languages are, Python, Matlab/Octave, Verilog, and C++. The studies are designed through the visual _concore_ Editor (DHGWorkflow) and interpreted into _concore_ through its parser. Neural control systems consist of loops (dicycles). Therefore, they cannot be represented by classic workflow standards (such as CWL or WDL). Therefore, _concore_ addresses a significant research gap to model closed-loop neuromodulation control systems. The _concore_ protocol shares data between the programs through file sharing, with no centralized entity (a broker or an orchestrator) to arbitrate communications between the programs. (In the distributed executions, the CONTROL-CORE Mediator enables connecting the disjoint pieces of the study through REST APIs).
+
+
+# Installation and Getting Started Guide
+
+Please follow the [ReadTheDocs](https://control-core.readthedocs.io/en/latest/index.html) documentation and the [_concore-lite_](https://github.com/ControlCore-Project/concore-lite) repository to get started quick.
+
+Installation instructions for concore can be found [here](https://control-core.readthedocs.io/en/latest/installation.html). Usage instructions can be found [here](https://control-core.readthedocs.io/en/latest/usage.html).
+
+For a detailed and more scientific documentation, please read our extensive [open-access research paper on CONTROL-CORE](https://doi.org/10.1109/ACCESS.2022.3161471). This paper has a complete discussion on the CONTROL-CORE architecture and deployment, together with the commands to execute the studies in different programming languages and programming environments (Ubuntu, Windows, MacOS, Docker, and distributed execution).
+
+
+# The _concore_ Repository
+
+_concore_ contains programs (such as physiological models or more commonly called "PMs" and controllers) and studies (i.e., graphml files that represents the studies as workflows). The _wrappers_ enable seamlessly extending a study into a distributed one with the CONTROL-CORE Mediator.
+
+_concore_ repository consists of several scripts at its root level. The demo folder consists of several sample programs and studies, mostly toy examples to learn the protocol. The ratc folder consists of the programs and studies of the rat cardiac experiments we developed with _concore_.
+
+If you have a bug to report in one of the CONTROL-CORE projects, please report it through relevant Issue Tracker. Similarly, please feel free to contribute your studies and code enhancements using pull requests. Questions and discussions can be made through the relevant Discussions forum.
+
+The _concore_ Issues can be reported [here](https://github.com/ControlCore-Project/concore/issues).
+
+The _concore_ discussion forum can be found [here](https://github.com/ControlCore-Project/concore/discussions).
+
+Please make sure to send your _concore_ pull requests to the [dev branch](https://github.com/ControlCore-Project/concore/tree/dev).

+# Summary
+
+The CONTROL-CORE framework is a flexible software platform for designing and implementing closed-loop Vagus Nerve Stimulation (VNS) [@romero2017closed] systems in programming languages in diverse software environments. Its modular workflow approach for closed-loop executions of the VNS simulations aims to facilitate modeling organ functions as physiological models (PMs) and therapeutic devices in their early stages in a software environment. 
+
+The CONTROL-CORE framework consists of the _concore_ protocol at its core. The _concore_ protocol allows seamless synchronized communication between the programs (such as PMs and controllers) that compose a study as a workflow. _concore_ enables simulations to run on different operating systems, be developed in various programming languages (such as Matlab, Python, C++, and Verilog), and be run locally, in containers, and a distributed fashion. 
+
+CONTROL-CORE also consists of a Mediator implementation that facilitates the distributed execution of _concore_ studies through REST calls over the Internet. The Mediator uses wrappers developed as part of _concore_ to communicate between programs at distributed sites. When the Mediator is deployed to enable inter-organization workflows with services spread across the Internet, access control and authentication mechanisms must be used to protect the shared data. The Mediator leverages the API key-based authentication provided by the Kong API gateway to enable such Internet deployment. Figure 1 shows an illustrative CONTROL-CORE deployment across 3 distributed sites, with a public instance of the Mediator.
+
+![A sample CONTROL-CORE distributed deployment spanning multiple sites](figures/joss-concore.png)
+
+CONTROL-CORE contains a lightweight browser-based visual _concore_ editor, which lets the users create studies from the programs in a drag-and-drop manner. It allows the creation of directed hypergraphs to represent the studies with closed-loop from modular programs and exporting the directed hypergraph workflows as GraphML files. _concore_ consists of a parser that parses and interprets the studies represented in the GraphML file and executes the studies seamlessly as modular workflows until a specified maximum time value for the study is met. This exit condition ensures the closed-loop workflow does not run forever, as closed-loop studies do not contain a predefined end step, unlike the classic workflows with an end step.
+
+# Statement of need
+
+Existing software ecosystems are not tailored for the modeling and simulation of closed-loop control systems developed in multiple programming languages. Containerization with frameworks such as Docker has become popular across the scientific community as containerization enables reproducible science with minimal effort. Workflow frameworks can execute a series of containerized programs without human-in-the-loop, with services/programs as predefined start and end steps. Workflows facilitate modular development as they enable the execution of a series of programs without manually managing each program individually. Typically, these programs are developed and shared across the users as containerized services. Such workflows do not have a cycle, by definition.
+
+On the other hand, a neuromodulation control system comprises feedback loops represented by directed cycles (dicycles). The presence of a dicycle violates the core tenet of classic workflow frameworks, such as Common Workflow Language (CWL) [@amstutz2016common] and Workflow Description Language (WDL) [@miller2006method], which expect the studies to be represented by a directed acyclic graph (DAG) [@gupta2017generation]. Furthermore, control systems run the same program multiple times as part of the execution with feedback. Consequently, overheads imposed by workflow frameworks, significantly when handling implementations across diverse programming languages and execution environments, are magnified in the case of a closed-loop execution.
+
+Interoperability plays a significant role in scientific research. Therefore, we should support the modeling and simulation of studies composed of programs developed in different programming languages, executing on different execution modes (local, distributed, or containerized). _concore_ is designed for efficiency in control systems' specific use cases, supporting interoperable communication and data exchange between programs from independent researchers. The simple file-based communication and synchronization of _concore_, without a centralized workflow orchestrator, enables interoperable executions with high performance.
+
+# Research works enabled by _concore_
+
+The _concore_ protocol has been used to simulate closed-loop control of cardiac physiological models, with various controllers such as Model Predictive Control and Long-Short-Term Memory-based controllers. The scientific contributions of _concore_ protocol and the CONTROL-CORE framework, along with these sample closed-loop neuromodulation control systems use cases, have been extensively discussed in our previous work [@kathiravelu2022control].

+^Removed plotting from controller
+
+*Converted to HR for compatibility with plotym.py
+
+
+Here amp refers to pulse amplitude simulation and wid refers to pulse width simulation.
+
+All of the controllers generate a "u" which is a vector that consists of 6 stimulation values. 3 of these are frequencies. The other 3 are either amplitudes or widths. All of the PMs generate a "ym" which is a vector that consists of Mean Arterial Pressure (MAP) and Heart Rate (HR).
+
+The studies and the respective programs that compose those studies are given below.
