Public Safety Broadband Cybersecurity

Ongoing
Along with the implementation of a nationwide public safety broadband network based on Long Term Evolution (LTE) technology, the network’s cybersecurity capabilities and features will be unique compared to traditional commercial mobile carriers due to public safety’s operational environment and...

Public Safety Broadband Requirements and Standards Project Description

Ongoing
PSCR has actively participated in the requirements gathering and standards development process for public safety communications since its inception in 2007. "The PSCR (Public Safety Communications Research) staff ... has traveled the world over, going to 3GPP meetings and going from a point where we...

Public Safety Communications Program

Ongoing
America’s first responders deal with emergencies every day. And whether it is a routine traffic stop, a multi-alarm fire, or a large-scale event, such as Hurricanes Harvey and Sandy, or the attacks on 9/11, the ability of first responders to communicate with each other--on-scene as well as through...

Public Safety Communications Research

Ongoing
Too often in critical situations communications the data exchanges between law enforcement and public safety agencies are hampered by equipment incompatibilities. In large part these incompatibilities are due to a lack of standards to provide a common, nationwide approach to telecommunications and...
Bad Quality Image pscr

Public Safety Image Quality

Ongoing
Here is our plan in a nutshell: Ask how first responders how their department uses photos and video Collect images that demonstrate the many ways first responders use photography Identify patterns—image and video quality problems that impact many first responders Stimulate innovation on novel camera...
Responsible Network Usage pscr

Public Safety Mobile Application Security

Ongoing
The nationwide public safety broadband network will provide first responders with modern access to data. This new access to multimedia (audio/video), situational awareness data, and operations functionality will enhance first responder’s effectiveness and efficiency. While mobile applications can...
Research Library Lobo

Publishing Services

Ongoing
The NIST Research Library occupies the unique position of serving NIST both as publisher of the NIST Technical Series, and in an archival capacity, responsible for collecting and preserving copies of NIST's grey literature. Over the last 15 years, the Library's publishing services have evolved from...

Pushing the Limits of Measurement Accuracy in Atom Probe Mass Spectrometry

Ongoing
Isotopic Analysis for Isotopic Geochemistry, Nuclear Safety, and Materials Science : Atom probe tomography has a significant advantage over other forms of mass spectrometry, which typically have a combined efficiency < 5%, in terms of ionization and detection efficiency. Commercial atom probe...
NIST developed test artifact for AM

Qualification for Additive Manufacturing Materials, Processes, and Parts

Completed
Objective: Develop test methods and protocols, provide reference data, and establish requirements to reduce the cost and time to qualify AM materials, processes, and parts. Technical Idea: Qualification of AM materials, processes, and parts is critical to enabling the AM industry to crack into the...

Qualification for AM Feedstocks, Machines and Processes

Completed
Objective - To develop, utilize, and analyze test methods and protocols for characterizing the feedstocks, machines, and processes in metal-based additive manufacturing to enable optimum usage and to reduce the cost and time needed for qualification. What is the Technical Idea? Qualification of AM...

Quality Assessment of Cryogenic Electron Microscopy Images

Ongoing
Manufacturing a vaccine based on packaging mRNA in lipid nanoparticles requires a full characterization of concentrations and distributions of mRNA and LNPs, as well as all manufacturing conditions. Such experiments generate hundreds of terabytes (TBs) of images and pose challenges on trusted...
DPO sensor

Quantifying the environmental contributions to mass change

Ongoing
Experiments using two types of centimeter scale oscillators are described: the double paddle oscillator (DPO) and a commercial quartz crystal microbalance (QCM). Double Paddle Oscillator (DPO) Since mass changes are mostly on the surface of mass artifacts, we have implemented a micro-weighing sensor...

Quantifying Uncertainty in Accelerometer Sensitivity Studies

Ongoing
DESCRIPTION: International Key Comparisons are performed. The key comparison reference value for charge sensitivity as a function of frequency and the accompanying uncertainty are the principal objectives of these studies. In a suggested mixed effects model several methods for evaluation of this...

Quantitative, Cell-based Immunofluorescence Assays

Completed
Analysis of signaling events within individual cells with microscopy imaging has several advantages over non-imaging techniques. The principal advantage of imaging cytometry over plate reader assays and even other single cell techniques such as flow cytometry is the potential for collection of...

Quantitative Flow Cytometry Measurements

Ongoing
Flow cytometry is an essential tool for: basic biotechnological and immunological research, the clinical discovery of potential therapeutics, development and approval of drugs and devices, disease diagnosis, and therapeutic treatment and monitoring For example, flow cytometry is commonly used in pre...

Quantitative Information from Images

Ongoing
Projects: Quantifying Amount of Material through Light Measurement Fluorescence and Luminescence Imaging for Surgical Guidance Fluorescence-guided imaging devices are being used for navigation in minimally invasive surgical procedures to increase a patient’s positive clinical outcomes and shorten...
MRI standards

Quantitative MRI

Ongoing
Future directions may focus on multimodal imaging, techniques that use MRI as either a base or as a complimentary technique. Multimodal imaging combines information from two or more imaging modalities such as MRI, computed tomography (CT), positron emission tomography (PET), and ultrasound (US)...
Schematic of unresolved imaging of a periodic structure. Extracting deep-subwavelength information from such images requires mastery of several techniques; this project seeks to integrate machine learning for metrology.

Quantitative Nanoscale Imaging Through Artificial Intelligence

Ongoing
This project extends optical capabilities for the characterization of nanoscale devices as they increase in complexity, with challenging new materials properties, thicknesses, and length scales that challenge simplistic applications of the fundamental equations of electromagnetism. Critical...
Quantum Hall System

Quantum anomalous Hall effect Theory

Ongoing
The quantum anomalous Hall effect is a phenomenon in which certain magnetic insulators exhibit a zero-field Hall resistance value, 𝑅 𝐻, that is precisely quantized in terms of fundamental constants of nature: 𝑅 𝐻 = ℎ/𝑛𝑒 2, where ℎ is Planck's constant, 𝑒 is the charge of the electron and 𝑛 is a...
