Monte Carlo Tool

This tool is used to implement Monte Carlo analysis, which uses probabilistic sensitivity analysis to account for uncertainty. This tool is developed to follow the simulation segment of ASTM E1369. This technique involves a method of model sampling. Specification involves defining which variables are to be simulated, the distribution of each of these variables, and the number of iterations performed. The software then randomly samples from the probabilities for each input variable of interest. Three common distributions that are used include triangular, normal, and uniform.

To illustrate, consider a situation where a firm has to purchase 100 ball bearings at $10 each; however, the price can vary plus or minus $2. In order to address this situation, one can use a Monte Carlo analysis where the price is varied using a triangular distribution with $12 being the maximum, $8 being the minimum, and $10 being the most likely. Moreover, the anticipated results should have a low value of approximately $800 (i.e., 100 ball bearings at $8 each) and a high value of approximately $1200 (i.e., 100 ball bearings at $12 each). The triangular distribution would make it so the $8 price and $12 price have lower likelihoods. For a Monte Carlo analysis, one must select the number of iterations that the simulation will run. Each iteration is similar to rolling a pair of dice, albeit, with the probabilities having been altered. In this case, the dice determine the price of the bearings. The number of iterations is the number of times this simulation is calculated (i.e., the number of times the dice is rolled).

Data from Influence of Fire on the Lateral Resistance of Cold-Formed Steel Shear Walls - Phase 2

Twenty-two 2.7 m by 3.7 m shear wall specimens consisting of 150 mm wide CFS framing were tested.  All walls were designed to achieve a 1-hour fire-resistance rating per American Society for Testing and Materials (ASTM) standard E119. Heating was applied to the side of the wall opposite to the side where the shear-resisting elements are located; it is assumed that the shear-resisting elements line an egress corridor and the fire occurs in a room adjacent to the corridor.  The walls are designed using Allowable Stress Design nominally following American Iron and Steel Institute (AISI) standards S400-15/S1-16 and AISI S100-16.

Analysis and Optical Modeling of Individual Heterogeneous Asian Dust Particles Collected at Mauna Loa Observatory

This project involved the analysis and optical modeling of atmospheric dust particles collected at Mauna Loa Observatory in Hawaii. Dust from the Asian mainland was identified in filter samples with computer-controlled scanning electron microscopy (CC-SEM). Individual Asian dust and marine background air particles were further examined using focused ion-beam (FIB) SEM and energy dispersive x-ray spectroscopy (EDX). The particles were heterogeneous in that they had multiple mineral phases, including an iron-containing phase which was compositionally minor but optically important. FIB tomography was used to produce 3-D reconstructions of the particles. The discrete dipole approximation (DDA) method for calculating optical properties was used to determine the light-scattering behavior of the particles based on the 3-D reconstructions. The dataset includes the following:
1) Tabulated optical property results for all selected particles in a single Excel file
2) Folder with CC-SEM data files
3) Folder and subfolders with particle SEM images and EDX element maps
4) Folder with Excel files with element composition, oxide composition, mineral composition, and mineral phase volumes for each particle
5) Folder and subfolders with optical modeling parameter files
6) Folder and subfolders with input and output files from the DDA program DDSCAT ver. 7.3.
7) Folder with Excel files with backscatter fraction calculations

2D Measurement of Retinal Pigment Epithelium Function Using Quantitative Bright-Field Microscopy

Induced Retinal Pigment Epithelial (iRPE) implants were developed from two healthy donors (Healthy-1 and Healthy-2). Live iRPE were imaged using quantitative bright-field absorbance microscopy (QBAM) every week during the in vitro maturation process. The data are organized by the culture plate, imaging date and time, color filter used to capture the images, and finally images that include the well ID and grid position in the name of the image. Both Healthy-1 and Healthy-2 iRPE were cultured in 12-well plates as outlined in Figure 1, with only half of the 12-well plate containing cells (green circles, Figure 1). The Blank Well (blue circles) was filled with culture medium but contained no cells and was used for benchmarking and calibration protocols that are part of the QBAM process. The grid in each well indicates that a 4x3 grid of overlapping images (~10-15% overlap) were captured for each well. One unique characteristic of this dataset is that each plate contains iRPE treated maturation inhibitors (negative control, HPI4), maturation promotors (positive control, Aphidicolin), or neither. The imaging parameters and functional data collected for each dataset for Healthy-1 and Healthy-2 were different, and the details of data collection and contents are included in the DataSummary.txt file included in each subfolder.

NIST Micronutrients Measurement Quality Assurance Program Winter and Summer 2017 Comparability Studies

The Micronutrients Measurement Quality Assurance Program (MMQAP) was coordinated by the Chemical Sciences Division and supported measurement technology for selected fat- and water-soluble vitamins and carotenoids in human serum. This program was initiated in 1984 by the National Cancer Institute Division of Cancer Prevention and Control to ensure the long-term reliability of the measurements made while studying the possible cancer chemoprevention roles of these compounds. This program provided participants with measurement comparability assessment through use of interlaboratory comparison studies, Standard Reference Materials and control materials, and methods development and validation. The MMQAP concluded in 2017, and parts of the MMQAP community will now be served through the NIST Health Assessment Measurements Quality Assurance Program (HAMQAP).

Data set of Flow Resistance Measurements of Vegetation

This data set reports measurements of the drag coefficient and geometric parameters of different types of vegetation. The vegetation chosen for this work was a Bakers Blue Spruce (Picea pungens `Bakeri'), an Evergreen Distylium (Distylium `PIIDIST-I'), a Gold Rider Leyland Cypress (Cupressocyparis leylandii `Gold Rider'), a Kimberly Queen Fern (Nephrolepis obliterata `Kimberly Queen'), a Blue Shag Eastern White Pine (Pinus strobus `Blue Shag'), and a Robin Red Holly (Ilex opaca). Each sample was chosen based on its local availability.  Wind resistance measurements are made in a wind tunnel with a 2.0 m test section and 0.5 m by 0.5 m cross-section. The drag coefficient is inferred via measurement of the pressure drop across the sample at wind speeds ranging from 2 m/s to 8 m/s. The data set also reports the white fraction, the absorption coefficient (Kappa,) and the solid fraction of each vegetation sample. The white fraction and absorption coefficients were determined via photography. The solid fractions were determined from water displacement testing. A detailed description of this work can be found in Ref. [1].

Hydrogen-Deuterium Exchange Mass Spectrometry (HDX-MS) Centroid Data measured between 3.6 degrees C and 25.4 degrees C for the Fab Fragment of NISTmAb

The spreadsheet file reported herein provides centroid data, descriptive of deuterium uptake, for the Fab Fragment of NISTmAb (PDB: 5K8A) reference material, as measured by the bottom-up hydrogen-deuterium exchange mass spectrometry (HDX-MS) method. The protein sample was incubated in deuterium-rich solutions under uniform pH and salt concentrations between 3.6 degrees C and 25.4 degrees C for seven intervals ranging (0 to 14,400) s plus a control sample that simulates a Fab Fragment immersed for infinite time in D2O. The deuterium content of peptic peptide fragments were measured by mass spectrometry. These data were reported by fifteen laboratories, which conducted the measurements using orbitrap and Q-TOF mass spectrometers. The cohort reported about 78,900 centroids for 430 proteolytic peptide sequences of the heavy and light chains of NISTmAb, providing nearly 100 % coverage. The instrumentation and physical and chemical conditions under which these data were acquired are documented.

Supplementary data for "Distributions of fitness effects for amino acid changes from high-throughout mutagenesis experiments" (McCandlish and Stoltzfus, 2018)

McCandlish and Stoltzfus gathered data from deep mutational scanning experiments on 12 proteins, comprising 56641 distinct amino acid replacement mutations.  By converting fitnesses to within-study quantiles, they combined results from all studies to draw general conclusions about distributions of fitness effects for the 380 different types of possible amino acid changes in proteins.  They found that most replacements are neither conservative nor radical, but barely different from the background distribution.  The shapes of these distributions can be approximated by a maximum-entropy model with only 1 parameter. This data package makes it possible to reproduce the main calculations used by Stoltzfus and McCandlish.  The data also may be useful to researchers carrying out meta-analyses of mutation-scanning experiments or DFE experiments.

Data for "Targeted Chemical Pressure Yields Tunable Millimeter-Wave Dielectric "

Included here are figures and other relevant data from the paper "Targeted Chemical Pressure Yields Tunable Millimeter-Wave 5G Dielectric with Unparalleled Performance" published online in Nature Materials on 23 December 2019 (https://doi.org/10.1038/s41563-019-0564-4). Abstract: Epitaxial strain can unlock enhanced properties in oxide materials but restricts substrate choice and maximum film thickness, above which lattice relaxation and property degradation occur. Here we employ a chemical alternative to epitaxial strain by providing targeted chemical pressure, distinct from random doping, to induce a ferroelectric instability with the strategic introduction of barium into today's best millimeter-wave tunable dielectric, the epitaxially strained 50 nm thick n = 6 (SrTiO3)nSrO Ruddlesden-Popper grown on (110) DyScO3. The defect mitigating nature of (SrTiO3)nSrO results in unprecedented low loss at frequencies up to 125 GHz. No barium-containing Ruddlesden-Popper titanates are known, but this atomically-engineered superlattice material, (SrTiO3)n?m(BaTiO3)mSrO, enables low-loss, tunable dielectric properties to be achieved with lower epitaxial strain and a 200 % improvement in the figure of merit at commercially-relevant millimeter-wave frequencies. As tunable dielectrics are key constituents for emerging millimeter-wave high-frequency devices in telecommunications our findings could lead to higher performance adaptive and reconfigurable electronics at these frequencies.

LTE Coverage Tool

This experimental Android application was developed by NIST PSCR to enable public safety personnel to measure general LTE coverage quality using a standard smartphone.  Source code is published on https://github.com/usnistgov/ as an SDK to allow developers to enhance the application or use it in other applications.

The application and SDK enable first responders and public safety personnel to survey and evaluate environments.  While accuracy of the data from UE measurements is much lower than that of specialized equipment, the application provides subjective assessments of coverage quality, using UEs which are already available to agencies and personnel.

Degradation Measurement of Robot Arm Position Accuracy

The dataset contains both the robot's high-level tool center position (TCP) health data and controller-level components' information (i.e., joint positions, velocities, currents, temperatures, currents). The datasets can be used by users (e.g., software developers, data scientists) who work on robot health management (including accuracy) but have limited or no access to robots that can capture real data. The datasets can support the:

- Development of robot health monitoring algorithms and tools
- Research of technologies and tools to support robot monitoring, diagnostics, prognostics, and health management (collectively called PHM)
- Validation and verification of the industrial PHM implementation. For example, the verification of a robot's TCP accuracy after the work cell has been reconfigured, or whenever a manufacturer wants to determine if the robot arm has experienced a degradation.

For data collection, a trajectory is programmed for the Universal Robot (UR5) approaching and stopping at randomly-selected locations in its workspace. The robot moves along this preprogrammed trajectory during different conditions of temperature, payload, and speed. The TCP (x,y,z) of the robot are measured by a 7-D measurement system developed at NIST. Differences are calculated between the measured positions from the 7-D measurement system and the nominal positions calculated by the nominal robot kinematic parameters. The results are recorded within the dataset. Controller level sensing data are also collected from each joint (direct output from the controller of the UR5), to understand the influences of position degradation from temperature, payload, and speed. Controller-level data can be used for the root cause analysis of the robot performance degradation, by providing joint positions, velocities, currents, accelerations, torques, and temperatures. For example, the cold-start temperatures of the six joints were approximately 25 degrees Celsius. After two hours of operation, the joint temperatures increased to approximately 35 degrees Celsius. Control variables are listed in the header file in the data set (UR5TestResult_header.xlsx).

Data to support Seasonal blubber steroid profiles of free-ranging bottlenose dolphins (Tursiops truncatus)

Liquid chromatography tandem mass spectrometry allows for the measurement of steroid hormone suites in the blubber of marine mammals.  By combining this technology with remote biopsy collection, endocrine profiles can be assessed, allowing for studies of hormonal profile variation over time.  In this study, we explored associations among different steroidogenic pathways and seasonal differences in blubber hormone profiles of free-ranging common bottlenose dolphins along the coast of South Carolina, USA.  We found that male dolphins experience a peak in testosterone, androstenedione, progesterone, and 17-hydroxyprogesterone in the spring, likely related to an upregulation of the androgen steroidogenic pathway during mating season.  We also observed increased cortisol concentrations not related to blubber lipid percentages during summer compared to other months.  Though the sample size of females was insufficient to describe female seasonal patterns, there was an increase in androstenedione among females with elevated progesterone concentrations indicative of pregnancy, highlighting another potential endocrine marker for pregnancy in free-ranging dolphins. This work emphasizes the importance of selecting the appropriate season for studies on endocrine status to effectively uncover physiological variation or disruption in free-ranging cetaceans.
