Physics and Astronomy Faculty Publications

We have constructed a mass-selected sample of M_* > 10¹¹ M_⊙ galaxies at 1 < z < 3 in the CANDELS UKIDSS UDS and COSMOS fields and have decomposed these systems into their separate bulge and disc components according to their H₁₆₀-band morphologies. By extending this analysis to multiple bands, we have been able to conduct individual bulge and disc component SED fitting which has provided us with stellar-mass and star formation rate estimates for the separate bulge and disc components. Having utilized the new decomposed stellar-mass estimates, we confirm that the bulge components display a stronger size evolution than the discs. The median sizes of the bulge components is 3.09 ± 0.20 times smaller than similarly massive local galaxies over the …

The Bulge–Disc Decomposed Evolution Of Massive Galaxies At 1 < Z < 3 In Candels, V. A. Bruce, J. S. Dunlop, R. J. Mclure, M. Cirasuolo, F. Buitrago, R. A. A. Bowler, T. A. Targett, E. F. Bell, D. H.

Physics and Astronomy Faculty Publications

We present the results of a new and improved study of the morphological and spectral evolution of massive galaxies over the redshift range 1 < z < 3. Our analysis is based on a bulge–disc decomposition of 396 galaxies with M_* > 10¹¹ M_⊙ uncovered from the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS) Wide Field Camera 3 (WFC3)/IR imaging within the Cosmological Evolution Survey (COSMOS) and UKIRT Infrared Deep Sky Survey (UKIDSS) UDS survey fields. We find that, by modelling the H₁₆₀ image of each galaxy with a combination of a de Vaucouleurs bulge (Sérsic index n = 4) and an exponential disc (n = 1), we can then …

Seqassist: A Novel Toolkit For Preliminary Analysis Of Next-Generation Sequencing Data, Yan Peng, Andrew S. Maxwell, Natalie D. Barker, Jennifer G. Laird, Alan J. Kennedy, Nan Wang, Chaoyang Zhang, Ping Gong

Faculty Publications

Background: While next-generation sequencing (NGS) technologies are rapidly advancing, an area that lags behind is the development of efficient and user-friendly tools for preliminary analysis of massive NGS data. As an effort to fill this gap to keep up with the fast pace of technological advancement and to accelerate data-to-results turnaround, we developed a novel software package named SeqAssist ("Sequencing Assistant" or SA).

Results: SeqAssist takes NGS-generated FASTQ files as the input, employs the BWA-MEM aligner for sequence alignment, and aims to provide a quick overview and basic statistics of NGS data. It consists of three separate workflows: …

Warming Reduces Tall Fescue Abundance But Stimulates Toxic Alkaloid Concentrations In Transition Zone Pastures Of The U.S., Rebecca L. Mcculley, Lowell P. Bush, Anna E. Carlisle, Huihua Ji, Jim A. Nelson

Plant and Soil Sciences Faculty Publications

Tall fescue pastures cover extensive acreage in the eastern half of the United States and contribute to important ecosystem services, including the provisioning of forage for grazing livestock. Yet little is known concerning how these pastures will respond to climate change. Tall fescue's ability to persist and provide forage under a warmer and wetter environment, as is predicted for much of this region as a result of climate change, will likely depend on a symbiotic relationship the plant can form with the fungal endophyte, Epichloë coenophiala. While this symbiosis can confer environmental stress tolerance to the plant, the endophyte …

A Spectroscopic Survey Of Wise -Selected Obscured Quasars With The Southern African Large Telescope, Kevin N. Hainline, Ryan C. Hickox, Christopher M. Carroll, Adam D. Myers

Dartmouth Scholarship

We present the results of an optical spectroscopic survey of a sample of 40 candidate obscured quasars identified on the basis of their mid-infrared emission detected by the Wide-Field Infrared Survey Explorer (WISE). Optical spectra for this survey were obtained using the Robert Stobie Spectrograph on the Southern African Large Telescope. Our sample was selected with WISE colors characteristic of active galactic nuclei (AGNs), as well as red optical to mid-IR colors indicating that the optical/UV AGN continuum is obscured by dust. We obtain secure redshifts for the majority of the objects that comprise our sample (35/40), and …

Optical Counterparts Of Two Fermi Millisecond Pulsars: Psr J1301+0833 And Psr J1628–3205, Miao Li, Jules P. Halpern, John R. Thorstensen

Dartmouth Scholarship

Using the 1.3 m and 2.4 m Telescopes of the MDM Observatory, we identified the close companions of two eclipsing millisecond radio pulsars that were discovered by the Green Bank Telescope in searches of Fermi Gamma-ray Space Telescope sources, and measured their light curves. PSR J1301+0833 is a black widow pulsar in a 6.5 hr orbit whose companion star is strongly heated on the side facing the pulsar. It varies from R = 21.8 to R > 24 around the orbit. PSR J1628–3205 is a "redback," a nearly Roche-lobe-filling system in a 5.0 hr orbit whose optical modulation in the range …

Between-Domain Relations Of Students' Academic Emotions And Their Judgments Of School Domain Similarity, Thomas Goetz, Ludwig Haag, Anastasiya A. Lipnevich, Melanie M. Keller, Anne C. Frenzel, Antonie P. M. Collier

Publications and Research

With the aim to deepen our understanding of the between-domain relations of academic emotions, a series of three studies was conducted. We theorized that between-domain relations of trait (i.e., habitual) emotions reflected students' judgments of domain similarities, whereas between-domain relations of state (i.e., momentary) emotions did not. This supposition was based on the accessibility model of emotional self-report, according to which individuals' beliefs tend to strongly impact trait, but not state emotions. The aim of Study 1 (interviews; N = 40; 8th and 11th graders) was to gather salient characteristics of academic domains from students' perspective. In Study 2 ( …

The Teacher Pay For Performance Phenomenon, Deborah Viscardi

Seton Hall University Dissertations and Theses (ETDs)

The purpose of this dissertation research was to explore the link between teacher motivation and performance-based compensation. This topic has been a controversial issue over the last decade across the country. There is a critical need for more research on teacher pay-for- performance systems, especially as it relates to motivation, student achievement, and the profession of teaching. Qualitative in design, the intent of this research study was to make meaning of teachers’ perceptions about the influence of performance-based compensation on the profession and practice of teaching. This study extends the current understanding and adds to the discussion of compensation policy …

Measurement Of Quasiparticle Transport In Aluminum Films Using Tungsten Transition-Edge Sensors, Jeffrey Yen, Benjamin Shank, Betty Young, Blas Cabrera, Paul Brink, Matthew Cherry, John Mark Kreikebaum, Robert Moffatt, Peter Redl, Astrid Tomada, Ted Tortorici

Faculty Publications

We report on experimental studies of phonon sensors which utilize quasiparticle diusion in thin aluminum films connected to tungsten transition-edge-sensors (TESs) operated at 35 mK. We show that basic TES physics and a simple physical model of the overlap region between the W and Al lms in our devices enables us to accurately reproduce the experimentally observed pulse shapes from x-rays absorbed in the Al films. We further estimate quasiparticle loss in Al lms using a simple diusion equation approach. These studies allow the design of phonon sensors with improved performance.

Exonest: Bayesian Model Selection Applied To The Detection And Characterization Of Exoplanets Via Photometric Variations, Ben Placek, Kevin H. Knuth, Daniel Angerhausen

Physics Faculty Scholarship

EXONEST is an algorithm dedicated to detecting and characterizing the photometric signatures of exoplanets, which include reflection and thermal emission, Doppler boosting, and ellipsoidal variations. Using Bayesian inference, we can test between competing models that describe the data as well as estimate model parameters. We demonstrate this approach by testing circular versus eccentric planetary orbital models, as well as testing for the presence or absence of four photometric effects. In addition to using Bayesian model selection, a unique aspect of EXONEST is the potential capability to distinguish between reflective and thermal contributions to the light curve. A case study is …

Field Trip Partnerships: Student-To-Student Mentoring, Aziza Darwish, Robyn Lee-Diaz

Publications & Research

Children running wild enjoying a day of freedom, exhausted chaperones, budget-conscious, hand-wringing administrators back at school -- all of these conjure troubling images for educators about field trips. These are far from the enjoyable, state-of-the-art, educational experiences that field trips could be for today's teachers and students.

For several years, the Illinois Mathematics and Science Academy® (IMSA) has had longstanding partnerships with school districts throughout the state which have involved designing STEM field trip experiences that serve middle school educators and students. These field trips to the Academy are led by IMSA high school students who are enrolled in the …

Distributed Owl El Reasoning: The Story So Far, Raghava Mutharaju, Pascal Hitzler, Prabhaker Mateti

Computer Science and Engineering Faculty Publications

Automated generation of axioms from streaming data, such as traffic and text, can result in very large ontologies that single machine reasoners cannot handle. Reasoning with large ontologies requires distributed solutions. Scalable reasoning techniques for RDFS, OWL Horst and OWL 2 RL now exist. For OWL 2 EL, several distributed reasoning approaches have been tried, but are all perceived to be inefficient. We analyze this perception. We analyze completion rule based distributed approaches, using different characteristics, such as dependency among the rules, implementation optimizations, how axioms and rules are distributed. We also present a distributed queue approach for the classification …

Self-Organizing The Space Of Vocal Imitations, Davide Rocchesso, Davide Andrea Mauro Phd

Computer Sciences and Electrical Engineering Faculty Research

The human voice is a powerful instrument for producing sound sketches. The sonic space that can be spanned with the voice is vast and complex and, therefore, it is difficult to organize and explore. In this contribution, we report on our attempts at extracting the principal components from a database of 152 short excerpts of vocal imitations. We describe each excerpt by a set of statistical audio features and by a measure of similarity of the envelope to a small number of prototype envelopes. We apply k-means clustering on a space whose dimensionality has been reduced by singular value decomposition, …

Beyond Sustainability: A New Conceptual Model, Molly Kerby, Gayle Mallinger

Gender & Women's Studies Faculty Publications

Over the last few decades, the notion of sustainability has become an interdisciplinary buzz word. Sustainability has been an integrative concept that includes three constructs or pillars: a) social; b) economic; and c) ecological. Until recently, theoretical approaches based on the three pillars approach have operated in silos rather than exploring the interconnectedness of the constructs. Few models have moved beyond the idea that logical relations exist among the constructs (social, economic, and ecological) to consider factors external to communities, nor have they examined the internal socio-economic factors that influence positive outcomes. While this conceptualization has raised awareness about the …

Spherical harmonic moments are well-suited for capturing anisotropy at any scale in the flux of cosmic rays. An unambiguous measurement of the full set of spherical harmonic coefficients requires full-sky coverage. This can be achieved by combining data from observatories located in both the northern and southern hemispheres. To this end, a joint analysis using data recorded at the Telescope Array and the Pierre Auger Observatory above 1019 eV is presented in this work. The resulting multipolar expansion of the flux of cosmic rays allows us to perform a series of anisotropy searches, and in particular to report on the …

Weighted Chebyshev Distance Algorithms For Hyperspectral Target Detection And Classification Applications, S. Demirci, I. Erer, Okan Ersoy

Department of Electrical and Computer Engineering Technical Reports

In this study, an efficient spectral similarity method referred to as Weighted Chebyshev Distance (WCD) is introduced for supervised classification of hyperspectral imagery (HSI) and target detection applications. The WCD is based on a simple spectral similarity based decision rule using limited amount of reference data. The estimation of upper and lower spectral boundaries of spectral signatures for all classes across spectral bands is referred to as a vector tunnel (VT). To obtain the reference information, the training signatures are provided randomly from existing data for a known class. After determination of the parameters of the WCD algorithm with the …
