Identifying Tactics of Advanced Persistent Threats with Limited Attack Traces

December 16, 2021
Author(s)
Khandakar Ashrafi Akbar, Yigong Wang, Md Islam, Anoop Singhal, Latifur Khan, Bhavani Thuraisingham1
The cyberworld being threatened by continuous imposters needs the development of intelligent methods for identifying threats while keeping in mind all the constraints that can be encountered. Advanced persistent threats (APT) have become an emerging issue

Quantitative Craniofacial Analysis and Generation of Human Induced Pluripotent Stem Cells for Muenke Syndrome: A Case Report

September 22, 2021
Author(s)
Fahad Kidwai, Byron Mui, Konstantinia Almpani, Priyam Jani, Cyrus Keyvanfar, Kulsum Iqbal, Sriram Paravastu, Deepika Arora, Pamela Orzechowski, Randall Merling, Barbara Mallon, Jeremiah Woodcock, Vamsee Myneni, Moaz Ahmad, Paul Kruszka, Maximilian Muenke, Pamela Robey, Janice Lee
In this case report, we focus on Muenke syndrome (MS), a disease caused by the p.Pro250Arg variant in fibroblast growth factor receptor 3 (FGFR3) and characterized by uni- or bilateral coronal suture synostosis, macrocephaly without craniosynostosis

Water Migration and Swelling in Engineered Barrier Materials for Radioactive Waste Disposal

January 25, 2021
Author(s)
Joanna McFarlane, Lawrence M Anovitz, Michael C. Cheshire, Victoria H. DiStefano, Hassina Z. Bilheux, Jean-Christophe Bilheux, Luke L. Daemen, Richard E. Hale, Ronald L. Howard, A. J. Ramirez-Cuesta, Louis J. Santodonato, Markus Bleuel, Daniel S. Hussey, David L. Jacobson, Jacob LaManna, Edmund Perfect, Logan Qualls
Deep underground repositories are needed to isolate radioactive waste from the biosphere. Bentonite is an integral component of many multibarrier repository systems. Information on the hydraulic behavior of bentonite is needed for modeling the long-term

Correlating Inter-Particle Forces and Particle Shape to Shear-Induced Aggregation/Fragmentation and Rheology for Dilute Anisotropic Particle Suspensions: A Complementary Study via Capillary Rheometry and in situ small and Ultra-Small Angle X-ray Scatterin

September 15, 2020
Author(s)
Anthony J. Krzysko, Elias Nakouzi, Xin Zhang, Trent R. Graham, Kevin M. Rosso, Gregory K. Schenter, Jan Ilavsky, Ivan Kuzmenko, Matthew G. Frith, Cornelius F. Ivory, Sue B. Clark, Javen S. Weston, Kathleen Weigandt, James J. De Yoreo, Jaehun Chun, Lawrence M. Anovitz
Predicting the stability of suspensions composed of anisotropic particles is difficult due to the complexity and interplay of hydrodynamic and colloidal forces. For example, it is not well understood how non-spherical particle shapes affect suspension

Protocol for Light-Shift Compensation in a Continuous-Wave Microcell Atomic Clock

September 8, 2020
Author(s)
Moustafa A. Hafiz, Remy Vicarini, Nicolas Passilly, Claudio Calosso, Vincent N. Maurice, Juniper Pollock, V Yudin, John Kitching, Rodolphe Boudot
Light shifts are known to be an important limitation to the mid- and long-term fractional frequency stability of different types of atomic clocks. In this article, we demonstrate the experimental implementation of an anti-light-shift interrogation protocol

Towards Formula Concept Discovery and Recognition

July 25, 2019
Author(s)
Howard S. Cohl, Philipp Scharpf, Moritz Schubotz, Bela Gipp
Citation-based Information Retrieval (IR) methods for scientific documents have proven to be effective in academic disciplines that use many references. In science, technology, engineering, and mathematics (STEM), researchers cite less often but employ

An Implementation Proposal for IEEE 802.11ay SU/MU-MIMO Communication in ns-3

June 21, 2019
Author(s)
Hany Assasa, Joerg Widmer, Jian Wang, Tanguy Ropitault, Nada T. Golmie
Wireless communications in the millimeter-wave band bring unprecedented capabilities to achieve wireline performance in wireless networks and alleviate the congestion problem of current wireless technologies. However, efficient wireless networking in this

Chemistry from 3D-printed objects

April 26, 2019
Author(s)
Matthew R. Hartings, Zeeshan Ahmed
3D printing technology has started to take hold as an enabling tool for scientific advancement. Born from the marriage of computer-aided design and additive manufacturing, 3D printing was originally intended to generate prototypes for inspection before

Probing the Participation of Oxygen Redox in the Electrochemical Cycling of Li-Rich Li2IrO3

March 25, 2019
Author(s)
Eric L. Shirley, John T. Vinson, Liang Li, Maria K. Chan, Joong S. Park, Eungje Lee, John W. Freeland, Zhenpeng Yao, Fernando Castro, Timothy T. Fister, Christopher M. Wolverton, Michael Thackeray
To exploit extra capacity beyond the traditionally postulated transition metal redox in Li-ion batteries, it is imperative to understand the exact role of oxygen in the charge compensation, i.e., what triggers the electron occupation change in oxygen and

Improved Calculation Method for Insulation-based Fire Resistance of Composite Slabs

March 2, 2019
Author(s)
Jian Jiang, Adam L. Pintar, Jonathan M. Weigand, Joseph A. Main, Fahim Sadek
A calculation method for estimating the fire resistance of composite slabs with profiled steel decking according to the thermal insulation criterion is provided in Annex D of Eurocode 4 (EC4). In this study, comparisons between validated high-fidelity

High-throughput assessment of vacancy formation and surface energies of materials using classical force-fields

September 7, 2018
Author(s)
Kamal Choudhary, Adam J. Biacchi, Supriyo Ghosh, Lucas M. Hale, Angela R. Hight Walker, Francesca M. Tavazza
In this work, we present an open access database for surface and vacancy-formation energies using classical force-fields (FFs). These quantities are essential in understanding diffusion behavior, nanoparticle formation and catalytic activities. FFs are

Energy Renormalization Method for the Coarse-Graining of Polymer Viscoelasticity

May 10, 2018
Author(s)
Jake Song, David D. Hsu, Kenneth R. Shull, Frederick R. Phelan Jr., Jack F. Douglas, Wenjie Xia, Sinan Keten
Developing time and temperature transferable coarse-grained (CG) models is essential for the computational prediction and design of polymeric glass-forming materials, but this goal has remained elusive. The dynamics of CG models are often greatly altered
