Intermediate Scattering Functions of a Rigid Body Monoclonal Antibody Protein in Solution Studied by Dissipative Particle Dynamic Simulation

April 8, 2021
Author(s)
Yanqin Zhai, Nicos Martys, William L. George, Joseph E. Curtis, Jannatun Nayem, Y. Z, Yun Liu
In the past decade, there is increased research interest in studying internal motions of flexible proteins in solution using Neutron Spin Echo (NSE) as NSE can simultaneously probe the dynamics at the length and time scale comparable to protein domain

Historical Review of the Metered Section Area for Guarded Hot Plates

December 31, 2019
Author(s)
Robert R. Zarr, Stacy M. Bruss, David McElroy
Results of an extensive literature review and investigation of the metered section area for the guarded-hot-plate method, standardized as ASTM C177, Standard Test Method for Steady-State Heat Flux Measurements and Thermal Transmission Properties by Means

CYBER-PHYSICAL SYSTEM DEVELOPMENT ENVIRONMENT FOR ENERGY APPLICATIONS

June 28, 2017
Author(s)
Thomas P. Roth, Yuyin Song, Martin J. Burns, Himanshu Neema, William Emfinger, Janos Sztipanovits
Cyber-physical systems (CPS) are smart systems that consist of highly interconnected networks of physical and computational components. The tight integration of a wide range of heterogeneous components enables new functionality and quality of life

Predicting low-temperature free energy landscapes with flat-histogram Monte Carlo methods

February 21, 2017
Author(s)
Nathan Mahynski, Marco A. Blanco Medina, Jeffrey R. Errington, Vincent K. Shen
We present a method of predicting the free energy landscape of fluids at low temperatures from flat-histogram grand canonical Monte Carlo simulations performed at higher ones. We illustrate our approach for both pure and multicomponent systems using two

Gas-Phase Interactions of Phosphorus Containing Compounds with Cup-Burner Diffusion Flames

September 20, 2016
Author(s)
Gregory T. Linteris, Fumiaki Takahashi, Viswanath R. Katta, Valeri I. Babushok
The effects of phosphorus-containing compounds (PCC) on the extinguishment and structure of methane-air coflow diffusion flames, in the cup-burner configuration, have been studied computationally. Dimethyl methylphosphonate (DMMP), trimethyl phosphate (TMP

The 2015 TWSTFT calibration for UTC and related time links

April 4, 2016
Author(s)
Zhiheng Jiang, Dirk Piester, Christian Schlunegger, Erik Dierks, Javier Galindo, Demetrios Matsakis, Victor S. Zhang
Two-Way Satellite Time and Frequency Transfer (TWSTFT or TW) is one of the primary time transfer techniques for UTC generation. Although it has expensive financial requirements it provides highly accurate calibration, and provides both robustness and

The IAPWS Industrial Formulation for the Thermodynamic Properties of Seawater

Author(s)
Allan H. Harvey, H J. Kretzschmar, Rainer Feistel, Wolfgang Wagner, Kiyoshi Miyagawa, J R. Cooper, Michael Hiegemann, Francisco L. Blangetti, Konstantin A. Orlov, I Weber, Anurag Singh, Sebastian Herrmann
… states such as vapor-brine and brine-ice (sea ice). The computing speeds for these calculations are faster than those …

The 3-D Shape of Blasted and Crushed Rocks: From 20 ?m to 38 mm

August 3, 2011
Author(s)
Edward J. Garboczi, Michael Taylor, Xuefeng Liu
Granodiorite material from a rock quarry in California was prepared by first quarrying large boulders, and then crushing down to smaller sizes. A range of particle sizes, from 0.0175 mm to 45.1 mm, was scanned using X-ray computed tomography (X-ray CT) and

BIOS Protection Guidelines

April 29, 2011
Author(s)
David Cooper, William Polk, Andrew Regenscheid, Murugiah Souppaya
This document provides guidelines for preventing the unauthorized modification of Basic Input/Output System (BIOS) firmware on PC client systems. Unauthorized modification of BIOS firmware by malicious software constitutes a significant threat because of

On Hash Functions Using Checksums

April 1, 2010
Author(s)
Praveen Gauruvarum, John M. Kelsey, L. Knudsen, S. Thomsen
We analyse the security of iterated hash functions that compute an input dependent checksum which is processed as part of the hash computation. We show that a large class of such schemes, including those using non-linear or even one- way checksum functions

Descriptive Metadata Requirements for Long-term Archival of Digital Product Models

February 25, 2009
Author(s)
Joshua Lubell, Ben Kassel, Sudarsan Rachuri
Digital product engineering information comes from a variety of applications ranging from computer-aided design, engineering, and manufacturing software to product data and lifecycle management systems. As the volume of digital engineering data increases

A New Optical Tweezers Technique Using a Holographic Crystal

February 1, 2004
Author(s)
E Edgu-Fry, Kristian Helmerson, Joseph E. Reiner, Rani B. Kishore
It has been shown previously that radiation pressure from a highly focused beam can be used to trap and manipulate objects in an aqueous media [1]. Over the past decade there have been several studies done by various groups to increase the ability of

Similarity Measures of Mass Spectra in Hilbert Spaces

July 29, 2024
Author(s)
Anthony J. Kearsley, Matthew Roberts
Mass spectrometry (MS) is an analytic tool for measuring mass-to-charge ratios of molecules or molecular fragments. It is often used to identify and classify compounds. A mass spectrometer measures the mass of molecules and produces a signal proportional
