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

Referencia basica de las capacidades de ciberseguridad de los dispositivos de IoT

March 31, 2021
Author(s)
Michael Fagan, Katerina N. Megas, Matt Smith, Karen Scarfone
Las capacidades de ciberseguridad de dispositivo son características o funciones de ciberseguridad que los dispositivos informáticos proporcionan por sus propios medios técnicos (es decir, el hardware y el software del dispositivo). Esta publicación define

Summary of the October 2020 Terminology Harmonization Meeting

March 31, 2021
Author(s)
Craig I. Schlenoff
On October 26, 2020, the Industrial Activities Board (IAB) of the IEEE Robotics and Automation Society (RAS) organized a virtual Terminology Harmonization Meeting in conjunction with the Intelligent Robots and Systems (IROS) Conference. The goal of the

A Machine Learning Based Scheme for Dynamic Spectrum Access

March 30, 2021
Author(s)
Anirudha Sahoo
In this paper, we present a machine learning (ML) based dynamic spectrum access (DSA) scheme which can be used in a system in which primary user (PU) spectrum occupancy can be represented as a sequence of busy (on) and idle (off) periods. We use real world

Securing Property Management Systems

March 30, 2021
Author(s)
Bill Newhouse
Hotels have become targets for malicious actors wishing to exfiltrate sensitive data, deliver malware, or profit from undetected fraud. Property management systems, which are central to hotel operations, present attractive attack surfaces. This example
