Srivalli Telikepalli, Kristen Gonzalez, Sonia Dragulin-Otto, Dean C. Ripple, Michael J. Carrier, M Khan
Visual inspection of biotherapeutics is required at various stages of drug production and manufacturing to ensure quality and consistency of drug products. Inherent particles, composed of aggregated protein from the drug-product, may potentially pose

Discriminated properties of PEI functionalized gold nanoparticles (Au-PEIs) predetermined by synthetic routes of ligand exchange and reduction processes: Paths and Fates

June 17, 2019
Author(s)
Tae Joon Cho, John M. Pettibone, Vincent A. Hackley
Polyethyleneimine (PEI) functionalized AuNPs (Au-PEIs) are have potent as positively charged gold nanoparticles (AuNPs) for nano-medicinal applications, due to their cationic surfaces that promote cellular uptake and gene transfection. 1-6 1-6 1-61-6 Au

Manipulation Data Collection and Annotation Tool for Media Forensics

June 17, 2019
Author(s)
Eric Robertson, Haiying Guan, Mark Kozak, Yooyoung Lee, Amy Yates, Andrew Delgado, Daniel F. Zhou, Timothee N. Kheyrkhah, Jeff Smith, Jonathan G. Fiscus
With the increasing diversity and complexity of media forensics techniques, the evaluation of state-of-the-art detectors are impeded by lacking the metadata and manipulation history ground-truth. This paper presents a novel image/video manipulation

The Blind Side: Using ‘Canned’ Loading Protocols in Seismic Testing

June 17, 2019
Author(s)
Matthew S. Speicher, Bruce F. Maison
The seismic behavior of a building component (e.g., shear wall) is a fundamental attribute engineers need to assess the earthquake performance of a building. It is no surprise that component behavior is often dependent on the loading history. Repeatedly

Two workshops were held to identify measurement challenges and potential solutions for building measurement assurance for flow cytometry. This report summarizes key findings, including the need for high quality reagents, reference standards or materials

Workshop 9: Control Cells or Not

June 17, 2019
Author(s)
Paul Wallace, Jonni S. Moore, Derek Jones, Litwin Virginia, Lili Wang, Yanli Liu
"Control Cells or Not" was an educational workshop that used surveys, lectures, and discussions to identify problems and solutions related to using commercially available control cell products and lab-developed approaches. Collective efforts are proposed

Building Design Considerations to Support Immediate Occupancy Performance Objectives

June 16, 2019
Author(s)
Siamak Sattar, Christopher Segura, Katherine Johnson, Therese P. McAllister, Steven McCabe
The intent of current building codes for typical commercial and residential buildings is to safeguard against loss of life to building occupants by minimizing the probability of structural collapse during natural hazard events. However, current codes do
