Chemical Herding As A Multiplicative Factor For Top-Down Manipulation Of Colloids, Mark N. Mcdonald, Douglas R. Tree, Cameron K. Peterson

Faculty Publications

Colloidal particles can create reconfigurable nanomaterials, with applications such as color-changing, self-repairing, and self-regulating materials and reconfigurable drug delivery systems. However, top-down methods for manipulating colloids are limited in the scale they can control. We consider here a new method for using chemical reactions to multiply the effects of existing top-down colloidal manipulation methods to arrange large numbers of colloids with single-particle precision, which we refer to as chemical herding. Using simulation-based methods, we show that if a set of chemically active colloids (herders) can be steered using external forces (i.e., electrophoretic, dielectrophoretic, magnetic, or optical forces), then a larger …

Effects Of Single-Session Practice Structure On Motor Skill Acquisition And Alpha And Beta Eeg Oscillations, Aubrey Porter, Ronald Victor Croce, Wayne Smith

Faculty Publications

Background: Although it is known that practicing a motor skill updates the associated internal model, it is still unclear as to how cortical oscillations linked with the motor skill change under differing practice schedules. The current study investigated α- and β-power changes associated with motor skill acquisition. Objectives: Firstly, we investigated the behavioral effects of practice on motor learning and retention during repetitive (RP) and variable (VP) practice schedules on an anticipation timing task. Secondly, we investigated changes in cortical α (10 - 13 Hz) and β (15 - 30 Hz) event-related synchronization and desynchronization (ERS/ERD) under RP and VP …

Under Pressure: The Interplay Of Hypertension And White Matter Hyperintensities With Cognition In Chronic Stroke Aphasia, Jade Hannan, Natalie Busby, Rebecca Roth, Janina Wilmskoetter, Roger Newman-Norlund Ph.D., Chris Rorden, Leonardo Bonilha, Julius Fridriksson Ph.D.

Faculty Publications

While converging research suggests that increased white matter hyperintensity load is associated with poorer cognition, and the presence of hypertension is associated with increased white matter hyperintensity load, the relationship among hypertension, cognition and white matter hyperintensities is not well understood. We sought to determine the effect of white matter hyperintensity burden on the relationship between hypertension and cognition in individuals with post-stroke aphasia, with the hypothesis that white matter hyperintensity load moderates the relationship between history of hypertension and cognitive function. Health history, Fazekas scores for white matter hyperintensities and Wechsler Adult Intelligence Scale Matrix Reasoning subtest scores for …

Mindfulness witnessed a substantial popularity surge in the past decade, especially as digitally self-administered interventions became available at relatively low costs. Yet, it is uncertain whether they effectively help reduce stress. In a preregistered (OSF https://doi.org/10.17605/OSF.IO/UF4JZ; retrospective registration at ClinicalTrials.gov NCT06308744) multi-site study (nsites = 37, nparticipants = 2,239, 70.4% women, Mage = 22.4, s.d.age = 10.1, all fluent English speakers), we experimentally tested whether four single, standalone mindfulness exercises effectively reduced stress, using Bayesian mixed-effects models. All exercises proved to be more efficacious than the active control. We observed a mean difference of 0.27 (d = −0.56; 95% confidence …

The results indicated that U.S. citizens had a positive affective and cognitive perception of Colombia, which led to …

Electrical Conductivity Of Subsurface Ocean Analogue Solutions From Molecular Dynamics Simulations, Catherine A. Psarakis, Timothy Tizhe Fidelis, Keith B. Chin, Baptiste Journaux, Abby Kavner, Pranb Sarker, Marshall J. Stycinski, Steven D. Vance, Tao Wei

Faculty Publications

Investigating the habitability of ocean worlds is a priority of current and future NASA missions. The Europa Clipper mission will conduct approximately 50 flybys of Jupiter’s moon Europa, returning a detailed portrait of its interior from the synthesis of data from its instrument suite. The magnetometer on board has the capability of decoupling Europa’s induced magnetic field to high precision, and when these data are inverted, the electrical conductivity profile from the electrically conducting subsurface salty ocean may be constrained. To optimize the interpretation of magnetic induction data near ocean worlds and constrain salinity from electrical conductivity, accurate laboratory electrical …

Recent microbiome research has incorporated a higher number of samples through more participants in a study, longitudinal studies, and metanalysis between studies. Physical limitations in a sequencing machine can result in samples spread across sequencing runs. Here we present the results of sequencing nearly 1000 16S rRNA gene sequences in fecal (stabilized and swab) and oral (swab) samples from multiple human microbiome studies and positive controls that were conducted with identical standard operating procedures. Sequencing was performed in the same center across 18 different runs. The simplified mock community showed limitations in accuracy, while precision (e.g., technical variation) was robust …

The Effects Of High-Pressure Annealing On Magnetostructural Transitions And Magnetoresponsive Properties In Stoichiometric Mncoge, Tej Poudel Chhetri, Jing Han Chen, David P. Young, Igor Dubenko, Saikat Talapatra, Naushad Ali, Shane Stadler

Faculty Publications

In this study, phase transitions (structural and magnetic) and associated magnetocaloric properties of stoichiometric MnCoGe have been investigated as a function of annealing pressure. Metastable phases were generated by annealing at 800 ° C followed by rapid cooling under pressures up to 6.0 GPa. The x-ray diffraction results reveal that the crystal cell volume of the metastable phases continuously decreases with increasing thermal processing pressure, leading to a decrease in the structural transition temperature. The magnetic and structural transitions merge and form a first-order magnetostructural transition between the ferromagnetic orthorhombic and paramagnetic hexagonal phases over a broad temperature range ( …

Flying Base Station Channel Capacity Limits: Dependent On Stationary Base Station And Independent Of Positioning, Sang-Yoon Chang, Kyungmin Park, Jonghyun Kim, Jinoh Kim

Faculty Publications

Flying base stations, also known as aerial base stations, provide wireless connectivity to the user and utilize their aerial mobility to improve communication performance. Flying base stations depend on traditional stationary terrestrial base stations for connectivity, as stationary base stations act as the gateway to the backhaul/cloud via a wired connection. We introduce the flying base station channel capacity to build on the Shannon channel capacity, which quantifies the upper-bound limit of the rate at which information can be reliably transmitted using the communication channel regardless of the modulation and coding techniques used. The flying base station’s channel capacity assumes …

Lignocellulosic Nanomaterial In An Oil-In-Water Emulsion Fluid System With Or Without An Emulsifier Sucrose Ester, Meen Sung Koo, Mohammad Shayan, Ragab Abouzeid, Qinglin Wu

Faculty Publications

The effect of lignocellulosic nanomaterial (LCNM) including lignin-containing cellulose nanofibers (LCNFs) and cellulose nanofibers (CNFs) on a diesel oil-in-water (O/W) emulsion was investigated with and without the emulsifier sucrose ester (SE). The O/W (65:35) emulsions were successfully stabilized by LCNFs with two lignin levels, while emulsions with CNFs exhibited large fiber flocs in the external phase only. High-lignin-content LCNFs led to a more uniform oil droplet size without formation of fiber flocs, whereas low-lignin-content LCNFs in emulsion revealed a wide size distribution of the oil droplets with intensive fiber flocs. The presence of SE significantly enhanced the stability of LCNM …

The quantitative findings were analyzed using descriptive statistics. Couples also participated in a semi-structured interview about the acceptability of RC-CPT, during …

Molecular Behavior Of Silicone Adhesive At Buried Polymer Interface Studied By Molecular Dynamics Simulation And Sum Frequency Generation Vibrational Spectroscopy, Yuchen Wu, Ting Lin, Elizabeth Santos, Dongchan Ahn, Ryan Marson, Pranab Sarker, Xiaoyun Chen, Frédéric Gubbels, Nick E. Shephard, Carol Mohler, Tao Wei, Tzu-Chi Kuoc, Zhan Chen

Faculty Publications

Silicones have excellent material properties and are used extensively in many applications, ranging from adhesives and lubricants to electrical insulation. To ensure strong adhesion of silicone adhesives to a wide variety of substrates, silane-based adhesion promotors are typically blended into the silicone adhesive formulation. However, little is known at the molecular level about the true silane adhesion promotion mechanism, which limits the ability to develop even more effective adhesion promoters. To understand the adhesion promotion mechanism of silane molecules at the molecular level, this study has used sum frequency generation vibrational spectroscopy (SFG) to determine the behavior of (3-glycidoxypropyl)trimethoxy silane …

A Flow-Curvature-Based Model For Channel Meandering In Tidal Marshes, Giulio Mariotti, Alvise Finotello

Faculty Publications

Channel meandering is ubiquitous in tidal marshes, yet it is either omitted or weakly implemented in morphodynamic models. Here we propose a novel numerical method to simulate channel meandering in tidal marshes on a Cartesian grid. The method calculates a first-order flow by considering the balance between pressure gradient and bed friction. To account for flow momentum shift toward meander outer banks, the flow is empirically modified. Unlike previous simplified methods that relied on the curvature of the bank, this modification is based on the curvature of the flow, making the model suitable for use in dendritic channel networks. The …

Patterns Of Marsh Surface Accretion Rates Along Salinity And Hydroperiod Gradients Between Active And Inactive Coastal Deltaic Floodplains, Andy F. Cassaway, Robert R. Twilley, Andre S. Rovai, Gregg A. Snedden

Faculty Publications

High subsidence rates are inherent to coastal deltas worldwide, contributing to rapid rates of relative sea-level rise and compromising the sustainability of coastal wetlands. Different parts of river deltas, however, experience accretion or erosion, depending on the coupling between ecological and morphological processes. Wetland expansion occurs in active deltaic coastal basins that are connected to riverine sedimentation. In contrast, wetland degradation occurs in inactive deltaic coastal basins where river engineering strategies associated with flood control restrict river connectivity. Here, we investigated the relative role of inorganic and organic loading to marsh accretion rates spanning fresh to brackish to saline zones …

Managed treatment wetlands technology is now used around the world to treat wastewater and stormwater by removing nutrients and other contaminants to obtain a desired water quality. In this paper we present a brief review of a large-scale application of the nature-based technology known as stormwater treatment areas (STAs). These STAs were constructed to treat agricultural and urban runoff to reduce outflow total phosphorus (TP) concentrations to < 20 μg P L⁻¹, which is required to protect downstream water quality and preserve the remaining Everglades ecosystem. Five STAs with a total area of approximately 25,000 ha were built at strategic locations to reduce …

Spatial And Temporal Distribution Of Juvenile Gulf Sturgeon In The Pearl River, Louisiana, And Adjacent Estuaries Of The Gulf Of Mexico, Ashley M. Baer, Glenn C. Constant, Kayla D. Kimmel, Michael A. Dance, Jenna N. Brogdon

Faculty Publications

Objective: Acoustic telemetry was used to examine the spatial-temporal distribution and anadromous migration pattern of juvenile Gulf Sturgeon Acipenser desotoi within the Pearl River and associated coastal estuaries of Louisiana and Mississippi. Methods: Acoustic transmitters were surgically implanted in 52 juvenile Gulf Sturgeon (< 890 mm fork length) from the Pearl River between 2016 and 2019. Sturgeon were monitored on 247 acoustic receivers in the lower Pearl River and adjacent estuaries across numerous partnering arrays. Result: Juveniles were detected on receivers from Lake Pontchartrain, Louisiana, east to Bay St. Louis, and Biloxi Bay, Mississippi. The 3-year study found that juvenile Gulf Sturgeon migration in the Pearl River occurred on cycles similar to those reported from other populations. Juveniles were rarely observed in the estuary and nearshore marine environments from May through mid-October of each year, during which time most sturgeon inhabited the Pearl River. Conversely, most of the juveniles inhabited coastal estuaries from December through February of each year and were rarely observed in freshwater environments during this period. Migration from the river into the estuary occurred during late-October through November, and migration from the estuary into the river occurred in March and April. Distribution patterns varied spatially within the river and estuary ecosystems during each phase of migration. Tagged juveniles occupied the lowest 40 km of the Pearl River while in freshwater, and they occupied the northeastern shoreline of Lake Pontchartrain and Bay St. Louis while in the estuary. Interestingly, juveniles seemed to target specific areas in the estuary during winter that were farther away from the mouth of natal rivers than has been previously reported. Conclusion: This study provides a new assessment of juvenile Gulf Sturgeon migration and seasonal distribution for the Pearl River and provides important information for designing and assessing the potential benefits and challenges of habitat restoration for Gulf Sturgeon.

The Policy And Politics Of Alternative Minimum Taxes, David Gamage, Ari Glogower

Faculty Publications

This paper contributes to a literature offering qualified justifications for alternative minimum tax (AMT) structures. We conclude that there is a narrow case for justifying AMTs even from the social planner perspective and that the proposed Billionaire’s Minimum Income Tax satisfies that narrow case. Next, incorporating governance collective action problems and electoral political constraints, we conclude that these considerations support a broader case for justifying AMTs that potentially also supports both preference-disallowance AMTs and the new corporate alternative minimum tax enacted in 2022.

A Snapshot Of How Mediators Use Technology These Days, John Lande

Faculty Publications

All professional mediators inevitably use technology these days. Indeed, they use it more than they realize. And, with the accelerating rate of technological developments, they generally will use it a lot more in the future. But it's not easy to incorporate technological developments into daily practice and keep up with the rapid pace of change. Part of the challenge is that mediators have their own unique complex practice systems that they aren't fully conscious of. And technology is integrated throughout their systems.

Faculty Publications

Targeted agents and immunotherapies have revolutionized cancer treatment, offering promising options for various cancer types. Unlike traditional therapies the principle of “more is better” is not always applicable to these new therapies due to their unique biomedical mechanisms. As a result, various phase I–II clinical trial designs have been proposed to identify the optimal biological dose that maximizes the therapeutic effect of targeted therapies and immunotherapies by jointly monitoring both efficacy and toxicity outcomes. This review article examines several innovative phase I–II clinical trial designs that utilize accumulated efficacy and toxicity outcomes to adaptively determine doses for subsequent patients and …

Evaluation Of Esterases Hydrolyzing Α-Naphthyl Acetate As Markers For Malathion Resistance In Culex Quinquefasciatus, Vivek Pokhrel, James A. Ottea

Faculty Publications

Early detection of insecticide resistance is essential to develop resistance countermeasures and depends on accurate and rapid biological and biochemical tests to monitor resistance and detect associated mechanisms. Many such studies have measured activities of esterases, enzymes associated with resistance to ester- containing insecticides, using the model substrate, α-naphthyl acetate (α-NA). However, in the field, pests are exposed to ester-containing insecticides such as malathion, that are structurally distinct from α-NA. In the current study, malathion resistance in C. quinquefasciatus (3.2- to 10.4-fold) was highly associated with esterase activity measured with either α-NA (R2 = 0.92) or malathion (R2 = 0.90). …

Pea Leaf Weevil, Sitona Lineatus (L.) (Coleoptera: Curculionidae), Adult Feeding Preference And Larval Development On Pulse Crop Varieties In Montana, Pragya Kiju, Kevin W. Wanner, Michael Ivie, Kevin Mcphee, Gadi V.P. Reddy

Faculty Publications

BACKGROUND: Montana accounts for approximately 45% of US dry pea production and the pea leaf weevil (PLW; Sitona lineatus (L.)) is the most common insect pest in this region. After crop emergence adult PLW feed on the foliage to mature and subsequently mate, and the soil-dwelling larvae feed and develop on the nitrogen-fixing root nodules. Producers commonly apply prophylactic insecticide treatments to the seed at planting as well as one or two post-emergent insecticide sprays to control PLW damage. To develop alternative management strategies based on integrated pest management (IPM), this field study evaluated pulse crops grown in Montana for …
