Larry Smarr has been collecting extensive data on his own health for over 5 years to study his diagnosis of Crohn's disease. Analysis of this data using genome sequencing and supercomputers has demonstrated the episodic evolution of his coupled immune-microbial system. High resolution metagenomic sequencing at JCVI and computational analysis with several CPU-decades of supercomputer time at SDSC has revealed the complex time-varying dynamics of Smarr's microbial ecology, shedding light on the autoimmune disease process. Comparisons to data from healthy individuals and those with IBD from the NIH Human Microbiome Project provide insights into how inflammation can alter the gut microbiome.
This document discusses how advances in genetic sequencing and computing are enabling humans to read and understand the "software of life" encoded in their human and microbiome DNA. It notes that the human microbiome contains millions of microbial genes compared to the 23,000 genes in human cells. The author details how the cost of DNA sequencing has fallen over 100,000-fold, allowing sequencing of both human and microbial genomes. Machine learning will be needed to understand differences between healthy and diseased states by analyzing enormous genomic and microbiome datasets. The author provides an example of analyzing their own gut microbiome over time and comparing to healthy/IBD populations.

EPOC and NetSage provide engagement and network monitoring services to support research and education. NetSage collects anonymized network flow data to help understand traffic patterns and troubleshoot performance issues. It provides dashboards and analysis to answer common questions from network engineers and end users. Examples of NetSage deployments and use cases were shown for the CENIC network, including top sources and destinations of traffic, debugging slow flows, and analyzing international traffic patterns by country over time.
The document discusses accelerating science discovery with AI inference-as-a-service. It describes showcases using this approach for high energy physics and gravitational wave experiments. It outlines the vision of the A3D3 institute to unite domain scientists, computer scientists, and engineers to achieve real-time AI and transform science. Examples are provided of using AI inference-as-a-service to accelerate workflows for CMS, ProtoDUNE, LIGO, and other experiments.
Democratizing Science through Cyberinfrastructure - Manish ParasharLarry Smarr
This document summarizes a presentation by Manish Parashar on democratizing science through cyberinfrastructure. The key points are:
1) Broad, fair, and equitable access to advanced cyberinfrastructure is essential for democratizing 21st century science, but there are significant barriers related to knowledge, technical issues, social factors, and balancing capabilities.
2) An advanced cyberinfrastructure ecosystem for all requires integrated portals, access to local and national resources through high-speed networks, diverse allocation modes, embedded expertise networks, and broad training.
3) Realizing this vision will require a scalable federated ecosystem with diverse capabilities and incentives for partnerships to meet growing needs for cyberinfrastructure and
Panel: Building the NRP Ecosystem with the Regional Networks on their Campuses;Larry Smarr
This document summarizes a panel discussion on building the National Research Platform ecosystem with regional networks. The panelists discussed how their regional networks are connecting to and using the Nautilus nodes of the NRP. Examples included using NRP for deep learning and computer vision research at the University of Missouri, challenges of adoption in Nevada and potential solutions, and Georgia Tech's new involvement through the Southern Crossroads regional network. The regional networks see opportunities to expand NRP access and training to enable more researchers in their regions to take advantage of the platform.
Open Force Field: Scavenging pre-emptible CPU hours* in the age of COVID - Je...Larry Smarr
The document discusses Open Force Field (OpenFF), an open-source project that enables rapid development of molecular force fields through automated infrastructure, open data and software, and an open science approach. OpenFF provides access to large quantum chemical datasets, runs quantum chemistry calculations on pre-emptible cloud resources with minimal human intervention, and facilitates easy iteration and testing of new force field hypotheses through an open development model.

The document discusses open infrastructure for an open society and the role of commercial clouds. It describes how the National Research Platform (NRP), Open Science Grid (OSG), and Open Science Data Federation (OSDF) provide open infrastructure through open source components that anyone can contribute to and use. It then discusses how Southwestern Oklahoma State University leveraged NRP resources on their campus and engaged students and local teachers. Finally, it outlines the pros and cons of commercial clouds, when they may be suitable to use, and how tools like CloudBank and Kubernetes can help facilitate science users' access to cloud resources.

Frank Würthwein - NRP and the Path forwardLarry Smarr
NRP will replace PRP and aims to democratize access to national research cyberinfrastructure. The long term vision is to create an open national cyberinfrastructure by federating resources across research institutions. Key innovations include an innovative network fabric, application libraries for FPGAs, a "bring your own resource" model, and innovative scheduling and data infrastructure. The NSF has funded the Prototype National Research Platform project to support NRP for the next 5 years. NRP aims to grow resources, introduce new capabilities, and be driven by the research community.

5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.

21. Why Did I Have an Autoimmune Disease like IBD?
Despite decades of research,
the etiology of Crohn's disease
remains unknown.
Its pathogenesis may involve
a complex interplay between
host genetics,
immune dysfunction,
and microbial or environmental factors.

the 163 Known SNPs Associated with IBD
• The width of the bar is proportional to the variance explained by that locus
• Bars are connected together if they are identified as being associated with both phenotypes
• Loci are labelled if they explain more than 1% of the total variance explained by all loci
