NIST Test Personal Identity Verification (PIV) Cards Version 2

April 2, 2021
Author(s)
David Cooper
In order to facilitate the development of applications and middleware that support the Personal Identity Verification (PIV) Card, NIST has developed a set of test PIV Cards and a supporting public key infrastructure (PKI). This set of test cards includes

Recalibration Intervals for Radiation Detection Instruments

April 2, 2021
Author(s)
Leticia Pibida, Ben Estes, Manuel Mejias, Gladys Klemic
In this work we provide a summary of the National Conference of Standards Laboratories (NCSL) Recommended Practice RP-1 calibration interval analysis method, and examples of the method applied to three sets of available NIST data (two models of radiation

A Spin Hamiltonian for BaCdVO(PO 4 ) 2

April 1, 2021
Author(s)
V. K. Bhartiya, S. Hayashida, K. Yu. Povarov, Z. Yan, Yiming Qiu, S. Raymond, A. Zheludev
Single crystal inelastic neutron scattering is used to study spin wave excitations in the fully polarized state of the frustrated quantum ferro-antiferromagnet BaCdVO(PO 4) 2. The data analysis is based on a Heisenberg spin Hamiltonian that includes as

Development of an LC-MS/MS Reference Method for the Standardization of Analytical Methods to Measure Lipoprotein(a) in Plasma

April 1, 2021
Author(s)
Santica Marcovina, Noemie Clouet-Foraison, Marlys Koschinsky, Mark Lowenthal, Michael Boffa, Andrew Hoofnagle, Tomas Vaisar
Background: Use of Lipoprotein(a) levels for identification of individuals at high risk for cardiovascular disease is hampered by the high size polymorphism of apolipoprotein(a) which strongly impacts immunochemical methods resulting in discordant values

Evidence Against Carbonization of the Thin-Film Filters of the Extreme Ultraviolet Variability Experiment onboard the Solar Dynamics Observatory

April 1, 2021
Author(s)
Charles Tarrio, Robert F. Berg, Thomas B. Lucatorto, Andrew Jones, Frank Eparvier, Brian Templeman, Donald Woodraska, Marie Dominique
In spite of strict limits on outgassing from organic materials, some spacecraft instruments making long-term measurements of solar extreme ultraviolet (EUV) radiation still suff er signi cant degradation. While such measures have reduced the rate of

Experimental study of shear and tensile properties of LIGA Ni-Fe and Ni-Co alloys at quasi-static and intermediate strain rates

April 1, 2021
Author(s)
Li-Anne Liew, David T. Read, May Martin, Todd R. Christenson, Peter E. Bradley, Nicholas Barbosa, Frank W. DelRio, John T. Geaney, Jeffrey Smyth
We report the in-plane shear properties, to fracture, of 200 um-thick LIGA nanocrystalline Ni- 10%Fe and micrograined Ni-10%Co. Planar simple shear specimens were designed, fabricated and pulled to fracture using a miniature commercial tension test stage

Facile fabrication and characterization of kraft lignin@Fe3O4 nanocomposites using pH driven precipitation: effects on increasing lignin content

April 1, 2021
Author(s)
Frankie A. Petrie, Justin Gorham, Robert T. Busch, Serhiy O. Leontsev, Esteban E. Urena-Benavides, Erick S. Vasquez
Kraft lignin@Fe3O4 multicore nanocomposites fabrication proceeded using a simple pH-driven precipitation technique. An alkaline solution for kraft lignin (pH 12) was rapidly injected into an aqueous-based magnetite (Fe3O4) nanoparticle colloidal suspension

New Practical Multivariate Signatures from a Nonlinear Modifier

April 1, 2021
Author(s)
Daniel Smith-Tone
Multivariate cryptography is dominated by schemes supporting various modifiers to patch certain algebraic weaknesses. Typically these modifiers are linear in nature--- either requiring an extra composition with an affine map, or being evaluated by a

Spectral Analysis of Line Edge and Line Width Roughness using Wavelets

April 1, 2021
Author(s)
Ndubuisi George Orji
Although line edge and line width roughness (LER/LWR) have been key metrology challenges over the last 15 years, the advent of extreme-ultraviolet lithography (EUV) has increased the importance of its measurement and control. Lithographically printed

Substrate-enhanced photothermal nano-imaging of surface polaritons in monolayer graphene

April 1, 2021
Author(s)
Samuel Berweger, Fabian Menges, Honghua Yang, Tao Jiang, Markus B. Raschke
Surface polaritons comprise a wealth of light-matter interactions with deep subwavelength scale confinement of electromagnetic modes. However, their nanoscale localized dissipation and thermalization processes are not readably accessible experimentally

Atividades Fundamentais de Ciberseguranca para Fabricantes de Dispositivos IoT

March 31, 2021
Author(s)
Michael Fagan, Katerina N. Megas, Matt Smith, Karen Scarfone
Os dispositivos da Internet das Coisas (IoT) muitas vezes não possuem recursos de segurança cibernética de acordo com os dispositivos que os seus clientes — organizações e indivíduos — querem usar para ajudar a mitigar riscos de segurança cibernética. Os

ISCMA: An Information Security Continuous Monitoring Program Assessment

March 31, 2021
Author(s)
Victoria Yan Pillitteri, Kelley L. Dempsey, Chad Baer, Ron Rudman, Robert Niemeyer, Susan Urban
This publication describes an example methodology for assessing an organization's Information Security Continuous Monitoring (ISCM) program. It was developed directly from NIST guidance and is applicable to any organization, public or private. It can be

Linha de Base do Nucleo de Recursos de Ciberseguranca de Dispositivos IoT

March 31, 2021
Author(s)
Michael Fagan, Katerina N. Megas, Matt Smith, Karen Scarfone
Os recursos de cibersegurança dos dispositivos são funções que os dispositivos de computação fornecem através dos seus próprios meios técnicos (ex: hardware e software do dispositivo). Esta publicação define uma linha de base dos recursos de cibersegurança
