Okalebo, C. Helzer, Anastasios Mazis, J. Hiller, Paolo Cherubini

School of Natural Resources: Faculty Publications

Remnant populations of Betula papyrifera have persisted in the Great Plains after the Wisconsin Glaciation along the Niobrara River Valley, Nebraska. Population health has declined in recent years, and has been hypothesized to be due to climate change. We used dendrochronological techniques to assess the response of B. papyrifera to microclimate (1950-2014), and satellite imagery [Landsat 5 TM (1985-2011) and MODIS (2000-2014)] derived NDVI as a proxy for population health. Growing-season streamflow and precipitation were positively correlated with raw and standardized tree-ring widths and basal area increment increase. Increasing winter and spring temperatures were unfavorable for tree growth while increasing …

Investigating Neural Sensorimotor Mechanisms Underlying Flight Expertise In Pilots: Preliminary Data From An Eeg Study, Mariateresa Sestito, Assaf Harel, Jeff Nador, John Flach

Psychology Faculty Publications

Over the last decade, the efforts toward unraveling the complex interplay between the brain, body, and environment have set a promising line of research that utilizes neuroscience to study human performance in natural work contexts such as aviation. Thus, a relatively new discipline called neuroergonomics is holding the promise of studying the neural mechanisms underlying human performance in pursuit of both theoretical and practical insights. In this work, we utilized a neuroergonomic approach by combining insights from ecological psychology and embodied cognition to study flight expertise. Specifically, we focused on the Mirror Neuron system as a key correlate for understanding …

The Influence Of Depth And Velocity On Age‐0 Scaphirhynchus Sturgeon Prey Consumption: Implications For Aquatic Habitat Restoration, T R. Gemeinhardt, Nathan J.C. Gosch, Anthony P. Civiello, Nathan J. Chrisman, Heather H. Shaughnessy, Tracy L. Brown, James M. Long, Joseph L. Bonneau

United States Army Corps of Engineers, Omaha District

After the pallid sturgeon (Scaphirhynchus albus) was listed as endangered in 1990, a variety of management actions focusing on early life history needs have been implemented to aid species recovery. Given the scarcity of age‐0 pallid sturgeon, managers and scientists have relied on sympatric congeners to evaluate the effectiveness of management actions in the short term; however, increased understanding of habitat requirements for age‐0 Scaphirhynchus sturgeon is still needed to appropriately focus management efforts. Recently, a lack of food‐producing and foraging habitats were proposed as potential limiting factors for pallid sturgeon, and the purpose of this study was to evaluate …

Schisms And Conflict Management In New African Immigrants’ Religious Organizations In The Greater Atlanta Area, Christina Edwards

Doctor of International Conflict Management Dissertations

New African immigrant religious organizations (NAIRO) are transnational religious organizations established and led by new African immigrants (NAI). These organizations are experiencing planned growth as outlined in their manuals, but little is known about the internal conflicts that lead to unplanned schisms or break away congregations. Foundational studies in the field of Sociology of Religion failed to include NAI-led churches in their studies and Atlanta was not selected as an immigrant hub city in their follow-up studies. This dissertation explores the social phenomenon of NAIRO internal conflicts that lead to unplanned schisms and therefore contribute to the overall growth of …

Electroactive Artificial Muscles Based On Functionally Antagonistic Core–Shell Polymer Electrolyte Derived From Ps-B-Pss Block Copolymer, Van Hiep Nguyen, Jaehwan Kim, Rassoul Tabassian, Moumita Kotal, Kiwoo Jun, Jung-Hwan Oh, Ji-Myeong Son, Muhammad Taha Manzoor, Kwang Jin Kim, Il-Kwon Oh

Mechanical Engineering Faculty Research

Electroactive ionic soft actuators, a type of artificial muscles containing a polymer electrolyte membrane sandwiched between two electrodes, have been intensively investigated owing to their potential applications to bioinspired soft robotics, wearable electronics, and active biomedical devices. However, the design and synthesis of an efficient polymer electrolyte suitable for ion migration have been major challenges in developing high-performance ionic soft actuators. Herein, a highly bendable ionic soft actuator based on an unprecedented block copolymer is reported, i.e., polystyrene-b-poly(1-ethyl-3-methylimidazolium-4-styrenesulfonate) (PS-b-PSS-EMIm), with a functionally antagonistic core–shell architecture that is specifically designed as an ionic exchangeable polymer electrolyte. The corresponding actuator shows exceptionally …

We report the first observation of the parity-violating gamma-ray asymmetry A(gamma)(np) in neutron-proton capture using polarized cold neutrons incident on a liquid parahydrogen target at the Spallation Neutron Source at Oak Ridge National Laboratory. A(gamma)(np) isolates the Delta I = 1, S-3(1)-> P-3(1) component of the weak nucleon-nucleon interaction, which is dominated by pion exchange and can be directly related to a single coupling constant in either the DDH meson exchange model or pionless effective field theory… See full text for full abstract.

The electrochemical CO reduction reaction (CO RR) is a promising approach for converting fossil fuel emissions into environmentally sustainable chemicals and fuels. The ability to control the surface structure of CO RR nanocatalysts provides an opportunity to tune product selectivity. Bimetallic gold-copper catalysts have been identified as emerging electrocatalyst candidates, but Cu incorporation typically lowers product selectivity compared with pure Au. Here we show sustained CO selectivity and activity up to 49% Cu content in small (<2 >nm), thiol-capped Au/Cu nanoparticles (NPs). Bimetallic NPs containing 49% Cu selectivity converted CO into CO with 100 ± 6% CO Faradaic efficiency and …

Limited Genetic Variability In Native Buckwheats (Eriogonum: Polygonaceae) On San Clemente Island, Lynn Riley, Mitchell E. Mcglaughlin, Kaius Helenurm

Western North American Naturalist

California Channel Island buckwheats are important components of scrub communities on the Channel Islands. A long history of overgrazing by introduced herbivores on San Clemente Island has contributed to scrub vegetation loss and population declines in 2 endemic island taxa, Eriogonum giganteum var. formosum and E. grande var. grande. Since herbivore removal, Eriogonum species, which are early colonizers of disturbed habitats, have been increasing across the island. These increases are thought to facilitate further recovery of the native flora because the shrubs act as nurse plants and improve the soil profile for other native species.

We genotyped individuals from both …

Precision Medicine In Pediatric Cancer: Current Applications And Future Prospects., Atif Ahmed, Divya S. Vundamati, Midhat S. Farooqi, Erin M. Guest

Manuscripts, Articles, Book Chapters and Other Papers

Precision oncologic medicine is an emerging approach for cancer treatment that has recently taken giant steps in solid clinical practice. Recent advances in molecular diagnostics that can analyze the individual tumor's variability in genes have provided greater understanding and additional strategies to treat cancers. Although tumors can be tested by several molecular methods, the use of next-generation sequencing (NGS) has greatly facilitated our understanding of pediatric cancer and identified additional therapeutic opportunities. Pediatric tumors have a different genetic make-up, with a fewer number of actionable targets than adult tumors. Nevertheless, precision oncology in the pediatric population has greatly improved the …

Practices That Attribute To The Success Of Boys: A Study Of Title I Middle Schools In Texas, Laura L. Duhon

Seton Hall University Dissertations and Theses (ETDs)

While it is commonly believed that boys are more successful than girls academically, research shows that boys are failing to thrive, academically, behaviorally, and socially. Boys comprise 70% of school suspensions as well as 80% of high school dropouts along with other alarming statistics. The purpose of this research study was to investigate approaches that contribute to the success of boys within six Title I middle schools located in various regions of Texas. These schools were selected based on state assessment (STAAR) scores where their male population was achieving the same or greater success as the females as measured by …

The Relationship Between Polychronicity And Social Networks: A Mixed-Methods Study Of Research And Development Professionals, Fabiola Bertolotti, Elisa Mattarelli, Janet Dukerich

Faculty Research, Scholarly, and Creative Activity

How do knowledge workers interact with their colleagues when organizations increasingly ask them to work on multiple activities, projects and working spheres simultaneously? Given the importance of social networks for individual and organizational success, in this study we explore the relationship between individual preferences for engaging in multiple tasks simultaneously (individual polychronicity), the perception of the organization’s demands in terms of engaging in multiple tasks simultaneously (organizational polychronicity), and centrality in instrumental networks. Adopting a mixed-methods approach, we collected data from knowledge professionals in a research and development (R&D) unit. Our results show that both individual and organizational polychronicity were …

Manganese-Enhanced Magnetic Resonance Imaging: Overview And Central Nervous System Applications With A Focus On Neurodegeneration, Ryan A. Cloyd, Shon A. Koren, Jose F. Abisambra

Physiology Faculty Publications

Manganese-enhanced magnetic resonance imaging (MEMRI) rose to prominence in the 1990s as a sensitive approach to high contrast imaging. Following the discovery of manganese conductance through calcium-permeable channels, MEMRI applications expanded to include functional imaging in the central nervous system (CNS) and other body systems. MEMRI has since been employed in the investigation of physiology in many animal models and in humans. Here, we review historical perspectives that follow the evolution of applied MRI research into MEMRI with particular focus on its potential toxicity. Furthermore, we discuss the more current in vivo investigative uses of MEMRI in CNS investigations and …

A Finalized Protocol For Testing Bovine Tendon To Study The Mechanical Effects Of Elastin, James Abraham, Spencer Lake

Mechanical Engineering and Materials Science Independent Study

Throughout this fall, I worked in Dr. Spencer Lake’s Musculoskeletal Soft Tissue Laboratory to finish developing a protocol and design setup to enable us to study the effects of elastin on the mechanical properties of tendon. These mechanical properties can be determined using an enzyme called elastase, which degrades elastin to the point where it is non-functional. Once the elastin is degraded, the mechanical properties of the tendon without elastin will be tested using an Instron. More specifically, I worked to develop a repeatable and well-defined protocol for testing, surveyed the literature on elastase incubation times, and developed smaller-scale tests …

Ammonia gas sensors are very essential in many industries and everyday life. However, their complicated fabrication process, severe environmental fabrication requirements and desorption of residual ammonia molecules result in high cost and hinder their market acceptance. Here, laser direct writing is used to fabricate three parallel porous 3D graphene lines on a polyimide (PI) tape to simply construct an ammonia gas sensor. The middle one works as an ammonia sensing element and the other two on both sides work as heaters to improve the desorption performance of the sensing element to ammonia gas molecules. The graphene lines were characterized by …
