Company

Theatre and Performance Studies Programs

TPS pays tribute to the titan of American Musical Theatre with a concert staging of this musical that features many of Sondheim’s beloved songs. How are your life decisions affected by the company you keep? Company takes us on Bobby's journey as the couples around him ponder his singlehood and encourage him to find a mate. We question whether his friends are living their own advice. Company is a delightful look at how society molds our ideals and how those ideals are translated into our relationships.

Impairment Of Igg Fc Functions Promotes Tumor Progression And Suppresses Nk Cell Antitumor Actions, Hao-Ching Hsiao, Kai Sun, Songlin Zhang, Robert E Jordan, Cheok Song Lee, Zhiqiang An, Ningyan Zhang

Faculty, Staff and Student Publications

Natural killer (NK) cells mediate antibody dependent cytotoxic killing of cancer cells via cross-linking FcγR on NK cells with IgG-Fc. Studies have shown that the single-hinge cleaved IgGs (scIgGs) have dysfunctional Fc and failed engagement with FcγRs on immune cells. However, little is known about how scIgGs impact on antitumor immunity in the tumor microenvironment. In this study, we revealed a significant association of tumor scIgGs with tumor progression and poor outcomes of breast cancer patients (n = 547). Using multiple mouse tumor models, we demonstrated that tumor scIgGs reduced NK cell cytotoxic activities and resulted in aggressive tumor progression. …

Adaptive Calibration Of Cubesat Radiometer Constellations, John Bradburn, Mustafa Aksoy

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

“Adaptive Calibration of CubeSat Radiometer Constellations” (ACCURACy) is a novel, constellation-level calibration framework developed to address the challenges in calibrating constellations of CubeSat radiometers. CubeSats are smaller than conventional monolithic systems, and so while cheaper and easier to develop and deploy, a lack of sufficient radiation shielding and thermal mass results in gain fluctuations due to the increased sensitivity to ambient conditions. Weight, cost, and power requirements also mean that CubeSats need to rely on vicarious calibration measurements, rather than external blackbody references, which cannot be collected frequently. ACCURACy is a multi-module framework which uses onboard telemetry data to cluster …

One of them is a laser/lamp-based table-top scatterometer (TTS) covering the spectral range from 300 nm to 2300 nm with a relative small beam size of 5 to 10 mm in diameter. The spatial non-uniformity of BRDF is requested when a large diffuse sample is measured on TTS. In order to test the BRDF along with spatial non-uniformity, a Large-area Uniform Illumination Scatterometer (LUIS) was built to meet the requirements for different large samples, especially volume diffuse samples. The LUIS system at NASA GSFC is capable …

Reliability Of Bridge Inspection Technologies, Glenn A. Washer

INSPIRE Archived Webinars

This presentation will discuss the reliability of inspection technologies used for the condition assessment of highway bridges. Data from condition assessments are critical to asset management and decision-making. The methodologies used to assess condition are usually subjective methods, such as visual inspections, that can vary as a result of human factors and differences in training and interpretation of inspection procedures. Nondestructive evaluation technologies (NDE) are implemented on a more limited basis and rely on indirect measurements to infer the presence of damage, and these assessments are affected by environmental factors, materials variability, and limitations in the interpretation of the resulting …

Small Sat Calibration, Cole Miller, Deron Scott, Eli Salay, Shane Canfield, Scott Hansen, Matt Berghout, Jan Kunzler, Duane Miles

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

Payloads used to make science measurements need calibration to characterize the instrument and ensure that mission objectives are met. When electro-optic instruments are developed for use on small satellite platforms, budgets and schedules are often restricted. There is a need to provide some calibration and still remain within budget. The goal of this project was to develop a calibration method to meet this challenge for small satellites. The effort includes spatial, spectral, and radiometric testing and characterization of small satellite payloads. Using a combination of sources, visible wavelength small satellite payloads can be calibrated cheaply and quickly. The calibration parameters …

Farmyard Animal Or Best Friend? Exploring Predictors Of Dog Vs. Pig Pet Speciesism, Sarah Gradidge, Magdalena Zawisza, Annelie J. Harvey, Daragh T. Mcdermott

People and Animals: The International Journal of Research and Practice

Despite dogs’ and pigs’ shared similarities, previous research indicates people favor dogs over pigs (known as “pet speciesism”). While pet speciesism has been empirically sup-ported, little is known about its predictors. This gap in the literature is problematic as urgent requirements to decrease meat consumption emphasize the pressing need to develop interventions to reduce pet speciesism and thus reduce meat consumption. However, to develop these interventions, we must first identify why people view pigs (vs. dogs) negatively. To begin addressing this gap, the current study utilized the stereotype content model to uniquely explore pet speciesism’s predictors. We recruited participants via …

Using the interview data, the authors built a demonstrative case that underlines the vulnerability of veterinary professionals and the potential of social work to improve the quality of their work experiences and longevity.

An Overview Of The Emerging P4001 Hyperspectral Standard, Christopher Durell, Torbjorn Skauli, John R. Gilchrist

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

Hyperspectral imaging has over the last thirty years developed into a power analytical tool for the determination of chemical and other properties. As a result, there has been strong development in both the design of spectral cameras and in the applications for which they are used. This has led to a diversity in the way fundamental instrument performances are characterized, reported, and understood. As a result, this makes it difficult to compare instruments for application-specific needs, or for commercial market needs.

In 2018, the IEEE P4001 group was formed to facilitate the development of a standard to unify the use …

A Novel Vacuum Fir Calibration System In Support Of Esa’S 9th Earth Explorer Mission At Ptb, J. Gieseler, M. Reiniger, D. Fehse, J. Schumacher, R. Hafner, A. Adibekyan, C. Monte

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

ESA’s 9th earth explorer mission Far-Infrared-Outgoing-Radiation Understanding and Monitoring (FORUM) aims for the first time to perform spectrally resolved, traceable measurements over extended time periods of earth’s outgoing FIR radiation in the wavelength range from 3.62 μm to 100 μm, providing valuable data for climate research, modeling and prediction. So far, only spectral measurements up to 17 μm have been realized. However, about half of earth’s outgoing total energy is found at wavelengths beyond 15 μm, making the FIR region crucial for earth’s energy budget and hence climate development. FORUM aims to close the data gap with an aspired absolute …

Recent Findings On Phosphorus Digestibility Of Feed Ingredients In Broilers, Jay Hampton, Wenting Li, Franco Mussini, Katie Hilton, Janet Remus, Samuel J. Rochell

Proceedings of the Arkansas Nutrition Conference

Accurately meeting the dietary P needs of broilers is critical to ensure optimal bird performance, health, and welfare without causing undue environmental burdens associated with excess dietary P excretion. Phosphorus is commonly supplied in broiler diets from inorganic phosphates derived from non-renewable sources, but it has been estimated that peak P production will occur between 2030-2040 and that the global supply of P could be depleted within this century (Cordell and Drangert, 2009; Nest and Cordell, 2012). To address these concerns, inorganic P use in agriculture, including use in broiler diet formulation, requires careful stewardship. To this end, the dietary …

Filter Design For Precise Spectral Performance In Wide-Field-Of-View Optical Systems, Chelsea D. Appleget, Frank Pan, Travis D. Thorne, Peter D. Fuqua, James D. Barrie

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

Wide field of view (WFOV) imaging systems can suffer from significant variations in performance from the center of the focal plane array (FPA) to the periphery of the detector. Some of these undesirable spatial variations include angle of incidence (AOI) of the marginal rays, illumination, and resolution non-uniformities. Optical designers are often required to go to great lengths to achieve adequate performance across the entire field of view, but these designs commonly possess high angles of incidence on optical surfaces and filters.

For optical coatings and bandpass filters, large AOIs have crucial implications for system performance, as the physics of …

Examining Water Sneak Paths, De-Ling Liu, Aileen Hu, Andrew Robbins, Rocky Morales, Hagop Barsamian

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

Water outgassed from spacecraft materials plays a key role in degrading cryogenic sensors, therefore characterizing “sneak paths” where water molecules can potentially migrate from sources external to payload to cryogenic surfaces becomes an important task to ensure proper sensor performance. Via modeling and laboratory testing, we examine water molecular transport mechanisms, and will show that sneak path testing at ambient pressure environment can be effective and expedient to help gain insights into molecular transport phenomenon under vacuum scenarios.
