A One Dimensional Elliptic Distributed Optimal Control Problem With Pointwise Derivative Constraints, Susanne C. Brenner, Li Yeng Sung, Winnifried Wollner Oct 2020

A One Dimensional Elliptic Distributed Optimal Control Problem With Pointwise Derivative Constraints, Susanne C. Brenner, Li Yeng Sung, Winnifried Wollner

Faculty Publications

We consider a one dimensional elliptic distributed optimal control problem with pointwise constraints on the derivative of the state. By exploiting the variational inequality satisfied by the derivative of the optimal state, we obtain higher regularity for the optimal state under appropriate assumptions on the data. We also solve the optimal control problem as a fourth order variational inequality by a C finite element method, and present the error analysis together with numerical results. 1

The Dynamic Trophic Niche Of An Island Bird Of Prey, Ulises Balza, Nicolas A. Lois, Michael J. Polito, Klemens Puetz, Amira Saalom, Andrea Raya Rey

Faculty Publications

Optimal foraging theory predicts an inverse relationship between the availability of preferred prey and niche width in animals. Moreover, when individuals within a population have identical prey preferences and preferred prey is scarce, a nested pattern of trophic niche is expected if opportunistic and selective individuals can be identified. Here, we examined intraspecific variation in the trophic niche of a resident population of striated caracara (Phalcoboenus australis) on Isla de los Estados (Staten Island), Argentina, using pellet and stable isotope analyses. While this raptor specializes on seabird prey, we assessed this population's potential to forage on terrestrial prey, especially invasive …

Faculty Publications

Quantitative surveys of fishes associated with artificial reefs in the northwest Gulf of Mexico were conducted over a 4-yr period (2014-2017). Artificial reefs surveyed were comprised of three types: concrete structures, rig jackets, and decommissioned ships. All reefs were surveyed using vertical long line ( VLL), fish traps, and Adaptive Resolution Imaging Sonar (ARIS 1800). Mean fish abundance did not significantly differ using VLL [1.7 ind set(-1) (SD 2.2)] among the three reef types. However, relative abundance among all fishes collected was significantly highest on rig reefs using traps [6.2 ind soak(-1) (SD 3.8)], while results from sonar surveys indicated …

Backbone And Sidechain Resonance Assignments And Secondary Structure Of Scc4 From Chlamydia Trachomatis, Thilini O. Ukwaththage, Marco Tonelli, Megan A. Macnaughtan

Faculty Publications

© 2020, Springer Nature B.V. Chlamydia trachomatis is an obligate intracellular bacterium that causes the most common sexually transmitted bacterial diseases in the world. With a biphasic developmental cycle, the bacteria utilize a type III secretion system (T3SS) to invade host cells as infectious elemental bodies, which then differentiate into actively dividing reticulate bodies. The regulation of the developmental cycle and the T3SS are linked by the bi-functional protein, specific Chlamydia chaperone 4 (Scc4). Scc4 is a class I T3SS chaperone forming a heterodimer with specific Chlamydia chaperone 1 (Scc1) to chaperone the essential virulence effector, Chlamydia outer membrane protein …

Faculty Publications

© 2020 Elsevier Inc. Notch receptors have large extracellular domains containing up to 36 tandem epidermal growth factor-like (EGF) repeats, which facilitate cell signaling by binding ligands on neighboring cells. Notch receptors play major roles in a variety of developmental processes by controlling cell fate decisions. Each EGF repeat consists of about 40 amino acids with 3 conserved disulfide bonds. Many of the EGF repeats are modified by O-linked fucose glycans, and more than half have calcium-binding sites, but the sequences of the EGF repeats vary giving distinct roles to each repeat. EGF repeat 27 (EGF27) from mouse NOTCH1 is …

Development, Education, And Implementation Of A Low-Cost Audio Sensor-Based Autonomous Surveillance System For Smart And Connected Transportation Infrastructure Construction And Maintenance, Yong-Cheol Lee, Jin-Woo Choi Ph.D

Data

Each DOT has to govern and oversee an enormous number of transportation construction and maintenance projects. However, since a transportation construction project entails several miles of a job site including numerous work tasks and equipment operations, it has been increasingly challenging for each DOT to consistently monitor progress of all projects in each State as well as efficiently evaluate work performance. In particular, with limited human resources and time, DOTs in Region 6 States have managed large-scale transportation construction and maintenance projects by a human inspection and recovered direct and indirect damages of transportation infrastructure systems caused from the recent …

Cosmic rays arriving at Earth collide with the upper parts of the atmosphere, thereby inducing extensive air showers. When secondary particles from the cascade arrive at the ground, they are measured by surface detector arrays. We describe the methods applied to the measurements of the surface detector of the Pierre Auger Observatory to reconstruct events with zenith angles less than 60 using the timing and signal information recorded using the water-Cherenkov detector stations. In addition, we assess the accuracy of these methods in reconstructing the arrival directions of the primary cosmic ray particles and the sizes of the induced showers.

Modelling R Coronae Borealis Stars: Effects Of He-Burning Shell Temperature And Metallicity, Courtney L. Crawford, Geoffrey C. Clayton, Bradley Munson, Emmanouil Chatzopoulos, Juhan Frank

Faculty Publications

The R Coronae Borealis (RCB) stars are extremely hydrogen-deficient carbon stars that produce large amounts of dust, causing sudden deep declines in brightness. They are believed to be formed primarily through white dwarf mergers. In this paper, we use mesa to investigate how post-merger objects with a range of initial He-burning shell temperatures from 2.1 to 5.4 × 108 K with solar and subsolar metallicities evolve into RCB stars. The most successful model of these has subsolar metallicity and an initial temperature near 3 × 108 K. We find a strong dependence on initial He-burning shell temperature for surface abundances …

The Type IIn supernova (SN IIn) 2005ip is one of the most well-studied and long-lasting examples of an SN interacting with its circumstellar environment. The optical light curve plateaued at a nearly constant level for more than five years, suggesting ongoing shock interaction with an extended and clumpy circumstellar medium (CSM). Here, we present continued observations of the SN from ∼1000 to 5000 d post-explosion at all wavelengths, including X-ray, ultraviolet, near-infrared (NIR), and mid-infrared. The UV spectra probe the pre-explosion mass loss and show evidence for CNO processing. From the bolometric light curve, we find that the total radiated …

The electron (anti-)neutrino component of the T2K neutrino beam constitutes the largest background in the measurement of electron (anti-)neutrino appearance at the far detector. The electron neutrino scattering is measured directly with the T2K off-axis near detector, ND280. The selection of the electron (anti-)neutrino events in the plastic scintillator target from both neutrino and anti-neutrino mode beams is discussed in this paper. The flux integrated single differential charged-current inclusive electron (anti-)neutrino cross-sections, dσ/dp and dσ/d cos(θ), and the total cross-sections in a limited phase-space in momentum and scattering angle (p > 300 MeV/c and θ ≤ 45°) are measured using a …

Third-Variable Effect Analysis With Multilevel Additive Models, Qingzhao Yu, Bin Li Oct 2020

Third-Variable Effect Analysis With Multilevel Additive Models, Qingzhao Yu, Bin Li

Faculty Publications

Third-variable effect refers to the effect transmitted by third-variables that intervene in the relationship between an exposure and a response variable. Third-variable effect analysis has been broadly studied in many fields. However, it remains a challenge for researchers to differentiate indirect effect of individual factor from multiple third-variables, especially when the involving variables are of hierarchical structure. Yu et al. (2014) defined third-variable effects that were consistent for all different types of response (categorical or continuous), exposure, or third-variables. With these definitions, multiple third-variables can be considered simultaneously, and the indirect effects carried by individual third-variables can be separated from …

Subglacial Antarctic aquatic environments are important targets for scientific exploration due to the unique ecosystems they support and their sediments containing palaeoenvironmental records. Directly accessing these environments while preventing forward contamination and demonstrating that it has not been introduced is logistically challenging. The Whillans Ice Stream Subglacial Access Research Drilling (WISSARD) project designed, tested and implemented a microbiologically and chemically clean method of hot-water drilling that was subsequently used to access subglacial aquatic environments. We report microbiological and biogeochemical data collected from the drilling system and underlying water columns during sub-ice explorations beneath the McMurdo and Ross ice shelves and …

Influence Of Powder Activated Carbon (Pac) In Fly Ash On The Properties Of Concrete, Zahid Hossain, Sumon Roy Oct 2020

Influence Of Powder Activated Carbon (Pac) In Fly Ash On The Properties Of Concrete, Zahid Hossain, Sumon Roy

Publications

Class C Fly Ash (CFA) is commonly used as supplementary cementitious material (SCM) in producing concrete by ready-mix concrete contractors in Arkansas. However, CFA can be used as a partial replacement of Ordinary Portland Cement (OPC) if it meets certain ASTM requirements. It is believed that the presence of powder activated carbon (PAC) in CFA increases the demand of the air-entraining agent (AEA) to achieve specified air content, and this is a concern to transportation agencies such as the Arkansas Department of Transportation (ARDOT) and concrete producers in recent years. Thus, the main goal of this research is to assess …

The purpose of this overview of systematic reviews was to determine the relationship between different types and patterns of sedentary behaviour and selected health outcomes in adults and older adults. Five electronic databases were last searched in May, 2019, with a 10-year search limit. Included reviews met the a priori population (community-dwelling adults aged 18 years and older), intervention/exposure/comparator (various types and/or patterns of sedentary behaviour), and outcomes criteria. Eighteen systematic reviews were included in the evidence synthesis. High levels of sedentary behaviour are unfavourably associated with cognitive function, depression, function and disability, physical activity levels, and physical health-related quality …

The original version of this article unfortunately contained an error in Fig. 6. The authors would like to correct the error with this erratum. The errors were due to the missing of a factor of 2 in the rate expression for the surface coverage of atomic H when it desorbs as H2, and to incorrect settings for some of the initial coverages, in the microkinetic model. A corrected version is shown here as Fig. 6, with the same caption as before.
