CRCNS - Microimaging/modeling of retinal responses measured with laser magnetometers

Igor Savukov, LANL Staff Scientist, NMC Affiliate
John George, NMC Research Scientist
 
The goal of this research is to conduct nuclear-spin optical rotation (NSOR) experiments at Texas A&M university in collaboration with the Dr. Christian Hilty at his dynamic nuclear polarization (DNP) facility. NSOR can be of interest to applications related to National Security and it is imperative that basic science be investigated in order to evaluate the potential for National Security applications.
 

Collaborative Research: DNP-Enhanced Nuclear Spin Optical Rotation Spectroscopy

Igor Savukov, LANL Staff Scientist, NMC Affiliate
 
The project goal is to conduct nuclear-spin optical rotation (NSOR) experiments at Texas A&M university in collaboration with Prof. Hilty. Previously, with Early Career LDRD funding this collaboration was established and some preliminary experiments were done at Texas A&M. The LDRD project has ended, but there are opportunities for continuing the research in this direction. Prof. Hilty has unique dynamic nuclear polarization (DNP) facility which is essential for the proposed project, and NSF funding mechanism is ideal for such collaboration. Dr. Savukov involvement will be the guidance of the experiments and analysis, remotely and at the site at Texas. NSOR can be of interest to applications related to National Security; however, at this initial stage of development basic science needs to be investigated in order to evaluate the potential for National Security applications. This project is sponsored by the NSF, and is a collaboration with Texas A&M.
 

Multidisciplinary investigation of the mammalian inner ear as  radio-frequency antenna, demodulator, and transducer

William Bruno, NMC Scientist
 
The NMC team will be modeling the electrical properties of the inner ear, in collaboration with University of Utah, and UNM, where radio-frequency experiments will be carried out on model antennas. Experiments on whether rodents respond to certain types of pulsed radio signals will be conducted by the Lovelace Biomedical Research Institute in Albuquerque.Other institutions participating in the program include Caltech, UCSD, University of Michigan, and Georgia Tech Research Institute. This research is funded by DARPA.

In this project the Higrad suite of codes is being ported to run on next generation architectures including the Intel Xeon Phi, GPUs such as the Nvidia architecture and larger numbers of multi-core processors. The scope of the work includes the development of test suites, code quality improvements, documentation, robustness, optimizations and finally the scaling of the application to run on tens to hundreds of thousands of processes.
 

Method for Testing Hydrophobic Materials for their Ability to Prevent Biofilm Formation and Why it is Important

Steven Buelow, NMC Chief Executive Officer and Scientist 

The objective of this project is to determine the relative susceptibility to biofilm formation on the surfaces of materials of various compositions, in samples provided by the National Aeronautics and Space Administration (NASA), exposed to actively growing algae in open cultivation ponds. This project is sponsored by NASA.

Turbulence and Particle Energization in Low-Beta Plasmas

Hui Li, LANL Staff Scientist
Xiangrong Fu, NMC Research Scientist
 

As part of the DoE/OFES project at LANL, this project performs advanced numerical simulations to study the current sheets and particle energization in turbulent plasmas. This has applications for  space, solar and astrophysical plasmas. Dr. Xiangrong Fu from the NMC has developed hybrid and  kinetic simulation techniques that can contribute to this project. He shall utilize these codes to  study the effects of turbulence on particle energization and identify possible applications of these  processes in systems such as solar wind, solar corona and accretion disk corona. This is an important part of our DoE/OFES project.

 

Fire Sciences

FIRETEC and WFDS Modeling of Fire Behavior and Smoke in Support of FASMEE

Rodman Linn, LANL Research Scientist and NMC Affiliate
Eunmo Koo, LANL Research Scientist
This project focuses on improving the fire behavior models, FIRETEC and WFDS, to support the Fire and Smoke Model Evaluation Experiment (FASMEE), a multi-agency effort focused on improving fire-behavior and wildfire plume-dynamics models.
 
Understanding and predicting wildfire behavior is a particularly difficult scientific problem, since the length scales of the physics range from those of flame sheets to fire and topography influenced atmospheric dynamics. Wildfires are driven by very complex processes ranging from combustion of complex natural fuels to local meteorology and their behavior depends heavily on the coupling between a variety of chemical and physical processes. The goal of this project is to improve upon the physics-based fire behavior models, FIRETEC and WFDS.
 
Both FIRETEC and WFDS models use computational fluid dynamics (CFD) methods to simulate the component physical processes that drive fire behavior. The validation of physics-based models, is supported by measurements of both the component physical processes and the resulting fire behavior. Large-scale field experiments, such as those proposed by FASMEE, are best suited for measurements of fire behavior. Validation of models for the component processes requires data sets from experiments in which many of the environmental conditions are very well characterized, thereby allowing a focus on one or a few physical processes of interest. This is best done in the controlled and repeatable conditions of laboratory or (potentially) small-scale field burns.

Seismic Research

Seismic sensor research includes:

Critical Stress

Jamaludin Mohd-Yusof, LANL Staff Scientist, NMC Affiliate

This project is looking at the application of sparse coding methods to extract relevant signals from seismic signals. This work includes using Petavision and other suitable machine learning software to develop a methodology to extract relevant signals from seismic sensors and to use that data to provide information about the location of the generators of those signals. 

High Resolution Seismic Imaging

 

Los Alamos National Laboratory has a number of projects on monitoring for geologic carbon storage and utilization and on geothermal energy exploration and reservoir monitoring. High-resolution seismic imaging is an essential part of these projects. In this project, scientists are working on analyzing multi-channel seismic data and perform high-resolution seismic imaging and inversion for subsurface characterization, reservoir monitoring and Earth's resources exploration.

Web Data Analysis

Towards a Web-Centric Approach for Capturing the Scholarly Record

Herbert Van de Sompel, LANL Staff Scientist and NMC Affiliate
Michael Nelson, Old Dominion University
Michael Wiegel, Old Dominion University
Harihar Shankar, LANL Staff Scientist and NMC Affiliate
Shawn Jones, Graduate Student, LANL, NMC Affiliate
Research communication has transitioned over time from a paperbased endeavor to a web-based digital enterprise, and now has started to evolve from being a largely hidden activity to being plainly visible on the global network. These transitions come with significant social, economical, legal, and technical challenges and even raise the question of what exactly the scholarly record is when all scholarship and scholarly communication is conducted on the global network. Irrespective of what the scholarly community will eventually decide regarding the delineation of the scholarly record on the web, an essential requirement will be to archive it. 
 
The goal of this research is to extend current web archiving activities so they are better suited for archiving the full range of scholarly materials. This project will also investigate methods for measuring and conveying archival quality as well as verifiability.
 
This research is a joint project between Old Dominion University, Los Alamos National Laboratory, and the New Mexico Consortium.
