Origami-Based Design Of Conceal-And-Reveal Systems, Bryce P. Defigueiredo, Kyler A. Tolman, Spencer P. Magleby, Nathan A. Pehrson, Erica Crampton, Larry L. Howell

Faculty Publications

This work introduces a type of motion termed “conceal-and-reveal” which is characterized by a state that protects a payload, a state that exposes the payload, and coupled motions between these two states. As techniques for thick, rigid origami-based engineering designs are being developed, origami is becoming increasingly more

attractive as inspiration for complex systems. This paper proposes a process for designing origami-based conceal- and-reveal systems, which can be generalized to design similar thick, rigid origami-based systems. The process

is demonstrated through the development of three conceal-and-reveal systems that present a luxury product to the consumer. The three designs also confirm …

Regional Stiffness Reduction Using Lamina Emergent Torsional Joints For Flexible Printed Circuit Board Design, Bryce P. Defigueiredo, Brian Dale Russell, Trent K. Zimmerman, Larry L. Howell

Faculty Publications

Flexible printed circuit boards (PCBs) make it possi- ble for engineers to design devices that use space efficiently

and can undergo changes in shape and configuration. How- ever, they also suffer from trade-offs due to non-ideal mate- rial properties. Here, a method is presented that allows en- gineers to introduce regions of flexibility in otherwise rigid

PCB substrates. This method employs geometric features to reduce local stiffness in the PCB, rather than reducing

the global stiffness by material selection. Analytical and fi- nite element models are presented to calculate the maximum

stresses caused by deflection. An example device is produced …

Soil Microbial Legacies Influence Freeze–Thaw Responses Of Soil, Melissa A. Pastore, Aimee T. Classen, Marie E. English, Serita D. Frey, Melissa A. Knorr, Karin Rand, E. Carol Adair

Faculty Publications

Warmer winters with less snowfall are increasing the frequency of soil freeze–thaw cycles across temperate regions. Soil microbial responses to freeze–thaw cycles vary and some of this variation may be explained by microbial conditioning to prior winter conditions, yet such linkages remain largely unexplored. We investigated how differences in temperature history influenced microbial community composition and activity in response to freeze–thaw cycles.

We collected soil microbial communities that developed under colder (high elevation) and warmer (low elevation) temperature regimes in spruce-fir forests, then added each of these soil microbial communities to a sterile bulk-soil in a laboratory microcosm experiment. The …

Seeing In The Dark: A Review Of The Use Of Side-Scan Sonar To Detect And Study Manatees, With An Emphasis On Latin America, Daniel Gonzalez-Socoloske, León David Olivera-Gómez

Faculty Publications

Manatees are aquatic mammals that live in a variety of environments. Many of those shallow water environments have murky water, making detection using traditional visual surveys very challenging. Side-scan sonar was first proposed as a tool to detect and study manatees in these complicated habitats in 2005. Here, we summarize the use of this tool from 2005 to 2022 by searching the available literature. Our literature search revealed that this tool is being widely used in more than 20 locations and over 15 countries. All three manatee species are being studied with side-scan sonar. It is most useful in murky …

On The Legal Life-History Of Beaches, Josh Eagle

Faculty Publications

Climate change is, among other things, making it more and more difficult to get to the beach. Recent studies show that rising sea levels have been shrinking America’s beaches through erosion and inundation. This trend is unlikely to slow down anytime soon, and some scientists predict that we will see feet of additional sea-level rise within our lifetimes. While beaches are shrinking, reducing the availability of recreational opportunities for locals and tourists alike, the number of people who want to visit the beach has grown dramatically. The growth in demand is due to a variety of factors, including the very …

Integrated Ion-Exchange Membrane Resin Wafer Assemblies For Aromatic Organic Acid Separations Using Electrodeionization, Matthew L. Jordan, Grzegorz Kokoszka, Hishara Keshani Gallage Dona, Dodangodage Ishara Senadheera, Revati Kumar, Yupo J. Lin, Christopher G. Arges

Faculty Publications

Aromatic acids, such as p-coumaric acid, are valuable chemical intermediates that are used in the specialty chemical industries because they are precursors to phenylpropanoid compounds. The separation of p-coumaric acid from fermentation broths is a critical step in the biochemical production process and more broadly the circular carbon economy. Electrodeionization (EDI) has been applied toward separations of low-carbon chain acids, but purifying p-coumaric acid has been challenging due to fouling and irreversible binding with ion-exchange membranes and resins. Here, we report a new membrane wafer assembly (MWA) consisting of laminated ion exchange membranes to porous ionomer-binder resin wafers for EDI. …

Chiral Uncertainties In Ab Initio Elastic Nucleon-Nucleus Scattering, Robert B. Baker, Matthew Burrows, Charlotte Elster, Kristina D. Launey, Pieter Maris, Gabriela Popa, Stephen P. Weppner

Faculty Publications

The effective interaction between a nucleon and a nucleus is one of the most important ingredients for reaction theories. Theoretical formulations were introduced early by Feshbach and Watson, and efforts of deriving and computing those ‘optical potentials’ in a microscopic fashion have a long tradition. However, only recently the leading order term in the Watson multiple scattering approach could be calculated fully ab initio, meaning that the same nucleon-nucleon (NN) interaction enters both the structure as well as the reaction pieces on equal footing. This allows the uncertainties from the underlying chiral effective NN interaction to be systematically explored in …

On Limitations Of Uniplex Networks For Modeling Multiplex Contagion, Nicholas W. Landry, Jimi Adams

Faculty Publications

Many network contagion processes are inherently multiplex in nature, yet are often reduced to processes on uniplex networks in analytic practice. We therefore examine how data modeling choices can affect the predictions of contagion processes. We demonstrate that multiplex contagion processes are not simply the union of contagion processes over their constituent uniplex networks. We use multiplex network data from two different contexts- (1) a behavioral network to represent their potential for infectious disease transmission using a "simple"epidemiological model, and (2) users from online social network sites to represent their potential for information spread using a threshold-based "complex"contagion process. Our …

Student, Classroom, And Teacher Factors Associated With Teachers’ Attunement To Bullies And Victims, Molly Dawes Ph.D., Angela Starrett, Kate Norwalk, Jill Hamm, Thomas Farmer

Faculty Publications

Teachers are instrumental in antibullying efforts given their position of authority in the classroom context, yet teachers can only be effective at reducing victimization and bullying in their classrooms if they are aware of who is involved. Consequently, teachers’ attunement to bullies and victims is a critical component of social dynamics management and antibullying practices. Given the importance of teacher attunement, there is a pressing need to identify relevant factors related to the degree to which teachers are attuned to bullies and victims. The major objective of the current investigation was to examine student- (gender, popularity status), classroom- (average bullying, …

Microplastics In Mainstem Mississippi River Fishes, Ahmed K. Gad, Kerrin Toner, Mark C. Benfield, Stephen R. Midway

Faculty Publications

Microplastics are ubiquitous in Earth’s ecosystems and many efforts have begun to understand their distributions. Large rivers, like the Mississippi River, provide a unique system in which to look at large-scale patterns of microplastic distribution. In this study, we sampled four species of widely-distributed fishes from five sites along the mainstem Mississippi River, from Minnesota to Louisiana, United States. Microplastics were found in all fish species and at all sites; however, microplastics increased in occurrence in the Lower Mississippi River. Fragments were the most common morphologies and polypropylene was the most common polymer detected. We also examined the hypothesis that …

Performance Of Rubberized Concrete And The Effect Of Temperature And Stainless Steel Fibers, Ayman El-Zohairy, Matthew Sanchez, Bahram Abediniangerabi, Perry Moler

Faculty Publications

Rubberized concrete is widely used in construction by utilizing the advantages of partially replacing fine or coarse aggregate with rubber to enhance several properties of concrete and provide an environmentally friendly solution. This paper experimentally explores the influence of utilizing crumb rubber (CR) as an alternate coarse aggregate in concrete. Concrete specimens were prepared with different percentages of rubber (0%, 5%, 10%, 15%, and 20%). Additionally, other parameters, such as freezing–thawing cycles, temperature, and stainless steel fibers (SSFs), were investigated. The workability of fresh concrete and the compression properties of hardened concrete were examined. Reductions in the mechanical properties of …

Dual Targeting Of Mtor/Il-17a And Autophagy By Fisetin Alleviates Psoriasis-Like Skin Inflammation, Tithi Roy, Sergette Banang-Mbeumi, Samuel T. Boateng, Emmanuelle M. Ruiz, Roxane Cherille N. Chamcheu, Lin Kang, Judy A. King, Anthony L. Walker, Bolni Marius Nagalo, Konstantin G. Kousoulas, Stephane Esnault, Shile Huang, Jean Christopher Chamcheu

Faculty Publications

Psoriasis is a chronic autoimmune inflammatory skin disorder characterized by epidermal hyperplasia and aberrant immune response. In addition to aberrant cytokine production, psoriasis is associated with activation of the Akt/mTOR pathway. mTOR/S6K1 regulates T-lymphocyte activation and migration, keratinocytes proliferation and is upregulated in psoriatic lesions. Several drugs that target Th1/Th17 cytokines or their receptors have been approved for treating psoriasis in humans with variable results necessitating improved therapies. Fisetin, a natural dietary polyphenol with anti-oxidant and anti-proliferative properties, covalently binds mTOR/S6K1. The effects of fisetin on psoriasis and its underlying mechanisms have not been clearly defined. Here, we evaluated the …

Faculty Publications

West Nile virus (WNV) causes annual outbreaks globally and is the leading cause of mosquito-borne disease in Unite States. In the absence of licensed therapeutics, there is an urgent need to develop effective and safe human vaccines against WNV. One of the major safety concerns for WNV vaccine development is the risk of increasing infection by related flaviviruses in vaccinated subjects via antibody-dependent enhancement of infection (ADE). Herein, we report the development of a plant-based vaccine candidate that provides protective immunity against a lethal WNV challenge mice, while minimizes the risk of ADE for infection by Zika (ZIKV) and dengue …

Effect Of Bovine Oocyte Vitrification With Egta And Post-Warming Recovery With Resveratrol On Meiotic Spindle, Mitochondrial Function, Reactive Oxygen Species, And Developmental Competence, Emilio Gutierrez-Castillo, Fabian A. Diaz, Sydney A. Talbot, Kenneth R. Bondioli

Faculty Publications

The present study aimed to determine the effects of the addition of EGTA to vitrification solutions and a post-warming recovery period supplemented with 1 μM resveratrol on meiotic spindle integrity, mitochondrial activity, ATP content, reactive oxygen species (ROS) levels, and developmental potential of partially denuded, vitrified-warmed bovine oocytes. Results of microtubule distribution and chromosomal arrangement indicated that resveratrol supplementation, irrespective to EGTA addition, reduced the incidence of abnormal meiotic spindles to similar levels of the control group. Mitochondrial membrane potential was similar in all groups, but ATP content was negatively affected by the vitrification-warming procedure and failed to recover after …

Response Of Marginal Height Costs And Marginal Height Benefits To Competition, Thomas J. Dean, Constance A. Harrington, Anthony D'Amato, Brian J. Palik

Faculty Publications

Height growth in trees is expensive in terms of the amount of stem tissue required to maintain productive tissue in sunlight. However, shifting allocation from stem support to leader growth and foliage production may allow trees to minimize shading effects on photosynthesis, especially for shorter trees within the population. This hypothesis was evaluated with data collected in competition studies for red alder (Alnus rubra Bong.), Douglas-fir (Pseudotsuga menziesii var. menziesii [Mirb.] Franco), and red pine (Pinus resinosa Ait.). Stem allocation per unit height growth was defined as a marginal height cost, and foliage added per unit height growth was defined …
