Deep Learning Image Analysis of Nanoplasmonic Sensors: Toward Medical Breath Monitoring

November 23, 2022
Author(s)
Yangyang Zhao, Boqun Dong, Kurt D. Benkstein, Lei Chen, Kristen L. Steffens, Stephen Semancik
Sensing biomarkers in exhaled breath offers a potentially portable, cost-effective, and noninvasive strategy for disease diagnosis screening and monitoring, while high sensitivity, wide sensing range, and target specificity are critical challenges. We

Developing multithreaded techniques and improved constraint handling for the tool CAgen

June 8, 2022
Author(s)
Michael Wagner, Manuel Leithner, Dimitris Simos, D. Richard Kuhn, Raghu N. Kacker
CAgen is a state-of-the-art combinatorial test generation tool that is known for its execution speed. In addition, it supports an extensive list of features such as constraint handling, higher-index arrays, and import and export of models/test sets in

Spatially-resolved bandgap and dielectric function in two-dimensional materials from Electron Energy Loss Spectroscopy

February 15, 2022
Author(s)
Abel Brokkelkamp, Jaco ter Hoeve, Isabel Postmes, Sabrya van Heijst, Luigi Maduro, Albert Davydov, Sergiy Krylyuk, Juan Rojo, Sonia Conesa Boj
The electronic properties of two-dimensional (2D) materials depend sensitively on the underlying atomic arrangement down to the monolayer level. Here we present a novel strategy for the determination of the band gap and complex dielectric function in 2D

Enhanced Magnetic Interaction by Face-Shared Hydride Anions in 6H-BaCrO 2 H

August 16, 2021
Author(s)
Kentaro Higashi, Masayuki Ochi, Yusuke Nambu, Takafumi Yamamoto, Taito Murakami, Naoya Yamashina, Cedric Tassel, Yuki Matsumoto, Hiroshi Takatsu, Craig Brown, Hiroshi Kageyama
Studies on magnetic oxyhydrides have been almost limited to perovskite-based lattices with corner-sharing octahedra with a M‒H‒M (M: transition metal) angle of θ 180 °. Using a high-pressure method, we prepared BaCrO 2H with a 6H-type hexagonal perovskite

Long-Range Magnetic Order in Hydroxide-Layer-Doped (Li 1-x-y Fe x Mn y OD)FeSe

March 11, 2020
Author(s)
Brandon Wilfong, Xiuquan Zhou, Huafei Zheng, Navneeth Babra, Craig Brown, Jeffrey W. Lynn, Keith M. Taddei, Johnpierre Paglione, Efrain E. Rodriguez
The (Li 1-xFe xOH)FeSe superconductor has been suspected to exhibit long-range magnetic ordering due to Fe substitution in the LiOH layer. However, no direct observation such as magnetic reflection from neutron diffraction has be reported. Here, we use a

Influence of optical system operation on stability of single tracks in selective laser melting

August 20, 2019
Author(s)
Ivan Zhirnov, Igor Yadroitsev, Brandon Lane, Sergey Mekhontsev, Steven Grantham, Ina Yadroitsava
Additive manufacturing (AM) technologies are increasingly being studied and introduced into the modern industry, but for wide applications there exists some "lack of confidence" about the quality of the parts produced by AM. This distrust has an objective

Industrial Robot Accuracy Degradation Monitoring and Quick Health Assessment

May 14, 2019
Author(s)
Guixiu Qiao, Brian A. Weiss
Robot accuracy degradation monitoring and assessment are critical activities in many industrial robot applications, especially when it comes to maintaining the high accuracy required operations, such as welding, material removal, robotic drilling, and

Rattling Behavior in a Simple Perovskite NaWO 3

May 1, 2019
Author(s)
Yuya Ikeuchi, Hiroshi Takatsu, Cedric Tassel, Craig Brown, Taito Murakami, Yuki Matsumoto, Yoshihiko Okamoto, Hiroshi Kageyama
A high-pressure reaction has allowed the preparation of stoichiometric tungsten bronze NaWO 3 (Im-3). Specific heat (C ;/T 3 vs T) exhibits a round peak at 30 K, indicating anharmonic phonon modes associated with low-energy rattling vibrations. Structural

Molecular Sieving of Ethylene from Ethane using a Rigid Metal-Organic Framework

November 26, 2018
Author(s)
Rui-Biao Lin, Libo Li, Hao-Long Zhou, Hui Wu, Chaohui He, Shun Li, Rajamani Krishna, Jinping Li, Wei Zhou, Banglin Chen
There are great challenges in developing efficient adsorbents to replace currently used and energy-intensive cryogenic distillation processes for olefin/paraffin separations, due to the similar physical properties of the two molecules. We report an

Model of Mobile Manipulator Performance Measurement using SysML

November 3, 2017
Author(s)
Roger V. Bostelman, Sebti Foufou, Tsai H. Hong, Mili Shah
Test methods for measuring safety and performance of mobile manipulators have yet to be developed. Therefore, potential mobile manipulator users cannot compare one system to another. Systems Modeling Language (SysML) is a general-purpose modeling language

Sucrose density gradient centrifugation for efficient separation of engineered nanoparticles from a model organism, Caenorhabditis elegans

October 11, 2017
Author(s)
Monique E. Johnson, Antonio R. Montoro Bustos, Elijah J. Petersen, Shannon K. Hanna, Karen E. Murphy, Lee L. Yu, Bryant C. Nelson, Michael R. Winchester
This protocol describes a strategy for separating Caenorhabditis elegans (C. elegans) from engineered nanomaterials, a critical step for accurate quantification in uptake studies. Conventional rinsing procedures, typically comprised of water or buffer

Time in Cyber-Physical Systems

October 2, 2016
