To Swim Or Not To Swim: A Population-Level Model Of Xenopus Tadpole Decision Making And Locomotor Behaviour, R Borisyuk, R Merrison-Hort, Sr Soffe, S Koutsikou, W-C Li

School of Engineering, Computing and Mathematics

We present a detailed computational model of interacting neuronal populations that mimic the hatchling Xenopus tadpole nervous system. The model includes four sensory pathways, integrators of sensory information, and a central pattern generator (CPG) network. Sensory pathways of different modalities receive inputs from an "environment"; these inputs are then processed and integrated to select the most appropriate locomotor action. The CPG populations execute the selected action, generating output in motor neuron populations. Thus, the model describes a detailed and biologically plausible chain of information processing from external signals to sensors, sensory pathways, integration and decision-making, action selection and execution and …

An Integrated Approach For The Installation Of A Wave Farm, N Arean, R Carballo, G Iglesias

School of Engineering, Computing and Mathematics

The installation of a wave farm involves the appropriate selection of a location and a wave energy converter (WEC) for harnessing the energy resource. There is typically a considerable number of options both regarding the site and the technology, and choosing the optimum WEC-site combination is not straightforward. An integrated approach is demonstrated in this work by means of a case study in Burela (Galicia, NW Spain)—an area that has been proposed for wave energy exploitation. First, three possible locations are defined with a view to avoiding potential environmental impacts and the interference of the wave farm with existing uses …

Onshore Wind Speed Modulates Microbial Aerosols Along An Urban Waterfront, M. Elias Drucker, Gregory D. O'Mullan, Joaquín Martínez Martínez, Andrew R. Juhl, Kathleen C. Weathers

Publications and Research

Wind blowing over aquatic and terrestrial surfaces produces aerosols, which include microbial aerosols. We studied the effect of onshore wind speeds on aerosol concentrations as well as total and culturable microbial aerosols (bacterial and viral) at an urban waterfront (New York, NY, USA). We used two distinct methods to characterize microbial aerosol responses to wind speed: A culture-based exposure-plate method measuring viable bacterial deposition near-shore (CFU accumulation rate); and a culture-independent aerosol sampler-based method measuring total bacterial and viral aerosols (cells m−3 air). While ambient coarse (>2 µm) and fine (0.3–2 µm) aerosol particle number concentrations (regulated indicators of …

Assessing Morphodynamics Of The Lower Mississippi River From 1985 To 2015 With Remote Sensing And Gis Techniques, Bo Wang

LSU Doctoral Dissertations

The Lower Mississippi River is one of the most highly engineered rivers in the world. The river is now completely regulated by a combination of levees, artificial cutoffs, bank revetments, and dike fields; however, the river engineering has also complicated the geomorphological response to the sediment brought in the river. This dissertation research examined morphodynamics of the middle portion of the Lower Mississippi River from Vicksburg, Mississippi (river kilometer: 737) to Red River Landing, Louisiana (river kilometer: 486) to elucidate river engineering effects on sediment transport, storage, and distribution. The Old River Control Structure (ORCS) diverts approximately 25% of the …

Double Neutron Stars: Merger Rates Revisited, M. Chruslinska, Krzysztof Belczynski, Matthew Benacquista

Physics & Astronomy Faculty Publications

We revisit double neutron star (DNS) formation in the classical binary evolution scenario in light of the recent Laser Interferometer Gravitational-wave Observatory (LIGO)/Virgo DNS detection (GW170817). The observationally estimated Galactic DNS merger rate of RMW = 21+28 −14 Myr−1, based on three Galactic DNS systems, fully supports our standard input physics model with RMW = 24 Myr−1. This estimate for the Galaxy translates in a non-trivial way (due to cosmological evolution of progenitor stars in chemically evolving Universe) into a local (z ≈ 0) DNS merger rate density of Rlocal = 48 Gpc−3 yr−1, which is not consistent with the …

Phosphoproteomics Profiling Of Nonsmall Cell Lung Cancer Cells Treated With A Novel Phosphatase Activator, Danica Wiredja, Marzieh Ayati, Sahar Mazhar, Jaya Sangodkar, Sean Maxwell, Daniela Schlatzer, Goutham Narla, Mehmet Koyutürk, Mark R. Chance

Computer Science Faculty Publications

Activation of protein phosphatase 2A (PP2A) is a promising anti-cancer therapeutic strategy, as this tumor suppressor has the ability to coordinately downregulate multiple pathways involved in the regulation of cellular growth and proliferation. In order to understand the systems-level perturbations mediated by PP2A activation, we carried out mass spectrometry-based phosphoproteomic analysis of two KRAS mutated non-small cell lung cancer (NSCLC) cell lines (A549 and H358) treated with a novel Small Molecule Activator of PP2A (SMAP). Overall, this permitted quantification of differential signaling across over 1,600 phosphoproteins and 3,000 phosphosites. Kinase activity assessment and pathway enrichment implicated collective downregulation of RAS …

The Safety Of Building Structures Subject To Unusual Natural And Man-Made Disasters, Pho Nguyen Van

ASEAN Journal on Science and Technology for Development

Previously, we often use the statistical data on natural disasters and mathematical tools such as probabilistic theory, mathematical statistics and random processes to express and analyze natural disasters' phenomena when dealing with the safety problem of building structures subject to natural disasters. However, due to unusual change of the global climate, natural disasters have changed essentially the intensity, frequency and the appearing time so we cannot rely on the statistical data on natural disasters in the past to do that. Therefore, renovation of the thought on selection of plans, calculation, design, and evaluation of safety of building structures to accommodate …

Investigating Habituation To Premonitory Urges In Behavior Therapy For Tic Disorders, David C. Houghton, Matthew R. Capriotti, Lawrence Scahill, Sabine Wilhelm, Alan L. Peterson, John T. Walkup, John Piacentini, Douglas W. Woods

Psychology Faculty Research and Publications

Behavior therapy is effective for Persistent Tic Disorders (PTDs), but behavioral processes facilitating tic reduction are not well understood. One process, habituation, is thought to create tic reduction through decreases in premonitory urge severity. The current study tested whether premonitory urges decreased in youth with PTDs (N = 126) and adults with PTDs (N = 122) who participated in parallel randomized clinical trials comparing behavior therapy to psychoeducation and supportive therapy (PST). Trends in premonitory urges, tic severity, and treatment outcome were analyzed according to the predictions of a habituation model, whereby urge severity would be expected to …

Characterization Of Laser-Generated Aluminum Plasma Using Ion Time-Of-Flight And Optical Emission Spectroscopy, Md. Haider A. Shaim, Hani E. Elsayed-Ali

Electrical & Computer Engineering Faculty Publications

Laser plasma generated by ablation of an Al target in vacuum is characterized by ion time-of-flight combined with optical emission spectroscopy. A Q-switched Nd:YAG laser (wavelength λ = 1064 nm, pulse width τ ∼ 7 ns, and fluence F ≤ 38 J/cm²) is used to ablate the Al target. Ion yield and energy distribution of each charge state are measured. Ions are accelerated according to their charge state by the double-layer potential developed at the plasma-vacuum interface. The ion energy distribution follows a shifted Coulomb-Boltzmann distribution. Optical emission spectroscopy of the Al plasma gives significantly lower plasma temperature …

Deglacial Tropical Atlantic Subsurface Warming Links Ocean Circulation Variability To The West African Monsoon, Matthew W. Schmidt, Ping Chang, Andrew O. Parker, Link Ji, Feng He

OES Faculty Publications

Multiple lines of evidence show that cold stadials in the North Atlantic were accompanied by both reductions in Atlantic Meridional Overturning Circulation (AMOC) and collapses of the West African Monsoon (WAM). Although records of terrestrial change identify abrupt WAM variability across the deglaciation, few studies show how ocean temperatures evolved across the deglaciation. To identify the mechanism linking AMOC to the WAM, we generated a new record of subsurface temperature variability over the last 21 kyr based on Mg/Ca ratios in a sub-thermocline dwelling planktonic foraminifera in an Eastern Equatorial Atlantic (EEA) sediment core from the Niger Delta. Our subsurface …

Regional Sea Level Variability And Trends, 1960-2007: A Comparison Of Sea Level Reconstructions And Ocean Syntheses, M. Carson, A. Köhl, D. Stammer, B. Meyssignac, J. Church, J. Schröter, M. Wenzel, B. Hamlington

OES Faculty Publications

Several existing statistical and dynamical reconstructions of past regional sea level variability and trends are compared with each other and with tide gauges over the 48 year period 1960-2007, partially predating the satellite altimetry era. Evaluated statistical reconstructions were built from tide-gauge data (TGR), and dynamical reconstructions from ocean data assimilation (ODA) approaches. Although most of the TGRs yield global-mean time series of sea level with trends deviating within ± 0.1 mm y^r-1, the spatial anomalies of the trends deviate substantially between the reconstructions over the period predating altimetry. In contrast, TGRs match observed regional trend patterns fairly …

Impact Of Automated Guidance For Mechanical Control Of Herbicide-Resistant Weeds In Corn, Terry Griffin, James M. Lowenberg-Deboer

Journal of Applied Farm Economics

This study evaluated the feasibility of reintroducing mechanical weed control as an alternative for herbicide-resistance weed infestations. The production practice tested included row cultivation with a separate banded spray application using high-accuracy automated guidance systems. A range of ground speeds were tested for the row cultivation operation, each with a different per acre cost and timeliness penalty. A typical eastern Corn Belt farm with a rotation of corn and soybean served as the base for the linear programming model. It was found that if the farmer was willing to reintroduce tillage, row cultivation conducted at higher operating speeds in conjunction …

We apply this information to an analysis of the common core curriculum to which the school is currently transitioning. The assessment analysis is designed to focus the class examples and homework assignments in pre-requisite courses to strengthen concepts needed during the AP Calculus class, and to assist teachers in planning concepts to re-teach in follow on classes. More broadly, our approach is a …

Understanding The Role Of The Common Core State Standards For Mathematics In Mathematics Methods And Mathematics Content Courses For Prospective Teachers, Sarah Ives, Anne Marie Marshall, Emerald Shee

Journal of Contemporary Research in Education

The reform efforts brought about by the Common Core State Standards for Mathematics (CCSSM) necessitate inquiry into how these standards are (or are not) being addressed in teacher preparation courses. This study examines the extent that the CCSSM are emphasized in mathematics content and mathematics methods courses for prospective teachers. We implemented a web-based survey and follow-up interviews of faculty from institutions across the nation. Results indicate a moderate level of variability in opportunities that prospective teachers have to learn about the CCSSM. Additionally, results show that mathematics teacher educators have changed their courses to include discussions around the CCSSM …

Being Nomadic In A Neo World, C. Steven Page, Rebecca G. Harper

Journal of Contemporary Research in Education

Teachers are often classified into groups based on performance, identity, and through the use of metaphors. This article utilizes a post structuralist lens to build on past research by posing the classification of teachers into three personas: the nematode, neo, and nomad. These personas are not always chosen by the teacher, but instead are reactions to environments, colleagues and administrators, and education mandates. Standardization and accountability, which are forced on education by neoliberal policies, affect teachers’ identities in negative ways and often cause them to be the type of teacher they never desired to be to their students. Utilizing Deleuze’s …
