Novel Topological Effects In Dense Qcd In A Magnetic Field, E.J. Ferrer, V. De La Incera

Publications and Research

We study the electromagnetic properties of dense QCD in the so-called Magnetic Dual Chiral Density Wave phase. This inhomogeneous phase exhibits a nontrivial topology that comes from the fermion sector due to the asymmetry of the lowest Landau level modes. The nontrivial topology manifests in the electromagnetic effective action via a chiral anomaly term $\theta F^{\mu\nu}\tilde{F}_{\mu\nu}$, with a dynamic axion field θ given by the phase of the Dual Chiral Density Wave condensate. The coupling of the axion with the electromagnetic field leads to several macroscopic effects that include, among others, an anomalous, nondissipative Hall current, an anomalous electric charge, …

Boundary Spanning At The Science–Policy Interface: The Practitioners’ Perspectives, A. T. Bednarek, C. Wyborn, C. Cvitanovic, R. Meyer, R. M. Colvin, P. F. E. Addison, S. L. Close, K. Curran, M. Farooque, E. Goldman, D. Hart, H. Mannix, B. Mcgreavy, Adam Parris, S. Posner, C. Robinson, M. Ryan, P. Leith

Publications and Research

Cultivating a more dynamic relationship between science and policy is essential for responding to complex social challenges such as sustainability. One approach to doing so is to “span the boundaries” between science and decision making and create a more comprehensive and inclusive knowledge exchange process. The exact definition and role of boundary spanning, however, can be nebulous. Indeed, boundary spanning often gets conflated and confused with other approaches to connecting science and policy, such as science communication, applied science, and advocacy, which can hinder progress in the field of boundary spanning. To help overcome this, in this perspective, we present …

Poster: Towards Safe Refactoring For Intelligent Parallelization Of Java 8 Streams, Yiming Tang, Raffi Khatchadourian, Mehdi Bagherzadeh, Syed Ahmed

Publications and Research

The Java 8 Stream API sets forth a promising new programming model that incorporates functional-like, MapReduce-style features into a mainstream programming language. However, using streams correctly and efficiently may involve subtle considerations. In this poster, we present our ongoing work and preliminary results to- wards an automated refactoring approach that assists developers in writing optimal stream code. The approach, based on ordering and typestate analysis, determines when it is safe and advantageous to convert streams to parallel and optimize a parallel streams.

Humanities And The Pursuit Of Happiness, Aldemaro Romero Jr.

Publications and Research

One question that is commonly asked of people who pursue a career in the humanities (like philosophy, literature, history and the like) is, “But what are you going to do for a living?” Even former President Barack Obama once ridiculed those following an art history career. These concerns are even more amplified in the case of first generation college students whose parents often- times expect them to follow more conventional careers, such as medicine, law or engineering.

Also, in the last few years there has been great hype about the STEM (Science, Technology, Engineering, and Mathematics) disciplines as the only …

Anomalous Electromagnetic Transport In Compact Stars, Efrain J. Ferrer, Vivian De La Incera

Publications and Research

We study the anomalous electromagnetic transport properties of a quark-matter phase that can be realized in the presence of a magnetic field in the low-temperature/moderate-high-density region of the Quantum Chromodynamics (QCD) phase map. In this so-called Magnetic Dual Chiral Density Wave phase, an inhomogeneous condensate is dynamically induced producing a nontrivial topology, a consequence of the asymmetry of the lowest Landau level modes of the quasiparticles in this phase. The nontrivial topology manifests in the electromagnetic effective action via a chiral anomaly term θF^µνF˜_µν, with an axion field θ given by the phase of the Dual …

Assessment Of A Single Decoupling Alchemical Approach For The Calculation Of The Absolute Binding Free Energies Of Protein-Peptide Complexes, Denise Kilburg, Emilio Gallicchio

Publications and Research

The computational modeling of peptide inhibitors to target protein-protein binding interfaces is growing in interest as these are often too large, too shallow, and too feature-less for conventional small molecule compounds. Here, we present a rare successful application of an alchemical binding free energy method for the calculation of converged absolute binding free energies of a series of protein-peptide complexes. Specifically, we report the binding free energies of a series of cyclic peptides derived from the LEDGF/p75 protein to the integrase receptor of the HIV1 virus. The simulations recapitulate the effect of mutations relative to the wild-type binding motif of …

Dissipation Effects In Schrödinger And Quantal Density Functional Theories Of Electrons In An Electromagnetic Field, Xiao-Yin Pan, Viraht Sahni

Publications and Research

Dissipative effects arise in an electronic system when it interacts with a time-dependent environment. Here, the Schrödinger theory of electrons in an electromagnetic field including dissipative effects is described from a new perspective. Dissipation is accounted for via the effective Hamiltonian approach in which the electron mass is time-dependent. The perspective is that of the individual electron: the corresponding equation of motion for the electron or time-dependent differential virial theorem—the ‘Quantal Newtonian’ second law—is derived. According to the law, each electron experiences an external field comprised of a binding electric field, the Lorentz field, and the electromagnetic field. In addition, …

Working Memory And Consciousness: The Current State Of Play, Marjan Persuh, Eric Larock, Jacob Berger

Publications and Research

Working memory (WM), an important posit in cognitive science, allows one to temporarily store and manipulate information in the service of ongoing tasks. WM has been traditionally classified as an explicit memory system—that is, as operating on and maintaining only consciously perceived information. Recently, however, several studies have questioned this assumption, purporting to provide evidence for unconscious WM. In this article, we focus on visual working memory (VWM) and critically examine these studies as well as studies of unconscious perception that seem to provide indirect evidence for unconscious WM. Our analysis indicates that current evidence does not support an unconscious …

An Empirical Study Of Chronic Diseases In The United States: A Visual Analytics Approach To Public Health, Wullianallur Raghupathi, Viju Raghupathi

Publications and Research

In this research we explore the current state of chronic diseases in the United States, using data from the Centers for Disease Control and Prevention and applying visualization and descriptive analytics techniques. Five main categories of variables are studied, namely chronic disease conditions, behavioral health, mental health, demographics, and overarching conditions. These are analyzed in the context of regions and states within the U.S. to discover possible correlations between variables in several categories. There are widespread variations in the prevalence of diverse chronic diseases, the number of hospitalizations for specific diseases, and the diagnosis and mortality rates for different states. …

Greer Studies, Teaches How To Improve Medicines, Aldemaro Romero Jr.

Publications and Research

“As a child, I was interested in asking questions. Like why different substances work the way they do and why they have some effect on our bodies. I was fascinated by hydrogen-peroxide and how it decomposes when you pour it on the wound. I would ask why it happens, what is the reason?” That’s how Dr. Edyta Greer explains how she became interested in science. A native of Poland, Greer received her master’s from Warsaw University and her doctorate from the Graduate Center of the City University of New York. Today she is an associate professor in the Department of …

To Do Or Not To Do: Dopamine, Affordability And The Economics Of Opportunity, Jeff A. Beeler, Devry Mourra

Publications and Research

Five years ago, we introduced the thrift hypothesis of dopamine (DA), suggesting that the primary role of DA in adaptive behavior is regulating behavioral energy expenditure to match the prevailing economic conditions of the environment. Here we elaborate that hypothesis with several new ideas. First, we introduce the concept of affordability, suggesting that costs must necessarily be evaluated with respect to the availability of resources to the organism, which computes a value not only for the potential reward opportunity, but also the value of resources expended. Placing both costs and benefits within the context of the larger economy in which …

The Disruption And Diversification Of Higher Education Funding: Cryptocurrency For Higher Education Wealth Generation, Edward Lehner, John R. Ziegler

Publications and Research

This work conceptualizes a process for cryptocurrency to diversify traditional methods of higher education funding in the United States. Higher education funding has seemingly reached an impasse, and opinions remain divided over both which societal parties should bear the educational costs for the vast majority of Americans and how to remedy the student debt crisis. Cryptocurrency funding augments traditional revenue streams, and shifts the discussion of education costs from expenses to a more robust conversation about innovative avenues to wealth generation as a potential solution to fund the mission of American higher education. Historically, higher education has been rooted in …

Bathymetry Data For Lakes Azuei And Enriquillo, Michael Piasecki, Mahrokh Moknatian

Publications and Research

This data set supports and forms the basis for the development of Digital Bathymetry Models (DBM) for Lakes Azuei (Haiti) and Enriquillo (Dominican Republic). Bathymetric Data is typically acquired using Sonar devices that measure the depth at specific points along a boat track and for which the longitude and latitude is recorded. From the resulting point cloud one develop a seamless representation of the floor of the lake on either a raster set (which is what we have done) or try to use a contour (vector representation) model in which the depth contours appear as polygons or -lines. The raw …

A Disk Origin For The Monoceros Ring And A13 Stellar Overdensities, Allyson A. Sheffield, Adrian M. Price-Whelan, Anastasios Tzanidakis, Kathryn V. Johnston, Chervin F.P. Laporte, Branimir Sesar

Publications and Research

The Monoceros Ring (also known as the Galactic Anticenter Stellar Structure) and A13 are stellar overdensities at estimated heliocentric distances of d ~ 11 kpc and 15 kpc observed at low Galactic latitudes toward the anticenter of our Galaxy. While these overdensities were initially thought to be remnants of a tidally disrupted satellite galaxy, an alternate scenario is that they are composed of stars from the Milky Way (MW) disk kicked out to their current location due to interactions between a satellite galaxy and the disk. To test this scenario, we study the stellar populations of the Monoceros Ring and …

In this paper we propose cryptosystems based on subgroup distortion in hyperbolic groups. We also include concrete examples of hyperbolic groups as possible platforms.

On The Use Of Semantic-Based Aig To Automatically Generate Programming Exercises, Laura Zavala, Benito Mendoza

Publications and Research

In introductory programming courses, proficiency is typically achieved through substantial practice in the form of relatively small assignments and quizzes. Unfortunately, creating programming assignments and quizzes is both, time-consuming and error-prone. We use Automatic Item Generation (AIG) in order to address the problem of creating numerous programming exercises that can be used for assignments or quizzes in introductory programming courses. AIG is based on the use of test-item templates with embedded variables and formulas which are resolved by a computer program with actual values to generate test-items. Thus, hundreds or even thousands of test-items can be generated with a single …

Interactive Whiteboards In Library Instruction: Facilitating Student Engagement And Active Learning, Maureen Richards, Marta Bladek, Karen Okamoto

Publications and Research

Determined to keep up with the ever-changing instructional trends, academic libraries have been quick to adopt emerging teaching and learning technologies. Recent literature features many examples of technologies that have found a place in libraries’ instructional programs: learning management systems, clickers, online tutorials, reference chats, and mobile devices, to mention the most popular ones. Curiously enough, despite their popularity in business and K-12 contexts, interactive whiteboards (IWBs) are rarely discussed in the context of academic libraries’ efforts to embrace innovative teaching methods. This article addresses this omission. Present-day IWBs have evolved to include features that accommodate a variety of teaching …

Positive Outcomes: Strategies For Assessing The Progress Of Youth Involved In The Justice System, Jeffrey A. Butts, Emily K. Pelletier, Lila Kazemian

Publications and Research

This report examines the shift in U.S. youth justice systems toward using adolescent development science to improve interventions and measure youth success. It emphasizes the adoption of Positive Youth Development (PYD) principles, which focus on fostering positive relationships and skills rather than just preventing recidivism. The report highlights various frameworks—such as the Developmental Assets model and Positive Youth Justice model—that align with PYD principles and research on desistance from crime. These frameworks offer a path for transforming youth justice systems into strengths-based approaches that promote long-term positive outcomes.

Predicting The Next Us President By Simulating The Electoral College, Boyan Kostadinov

Publications and Research

We develop a simulation model for predicting the outcome of the US Presidential election based on simulating the distribution of the Electoral College. The simulation model has two parts: (a) estimating the probabilities for a given candidate to win each state and DC, based on state polls, and (b) estimating the probability that a given candidate will win at least 270 electoral votes, and thus win the White House. All simulations are coded using the high-level, open-source programming language R. One of the goals of this paper is to promote computational thinking in any STEM field by illustrating how probabilistic …

Higher Ed Is In Need Of Fresh Ideas, Aldemaro Romero Jr.

Publications and Research

One common expression in the English language, particularly on this side of the Atlantic, is to refer to unexpected or crazy ideas as coming “out of left field.” The expression originated from baseball, specifically after Wrigley Field, home of the Chicago Cubs, was built in 1914. In what is today the left field of the stadium, there used to be what was then called a mental asylum. So when something crazy or unforeseen happened it was said to be “out of the left field.”

Some of the greatest ideas in the history of civilization came “out of the left field.” …

Burden Of Rheumatoid Arthritis Among Us Medicare Population: Co-Morbidities, Health-Care Resource Utilization And Costs, Chieh-I Chen, Li Wang, Wenhui Wei, Huseyin Yuce, Kristine Phillips

Publications and Research

Objectives. The study aimed to assess the burden of RA among the US Medicare population (aged 65 years) by comparing co-morbidities, health-care resource utilization (HCRU) and costs against matched non-RA Medicare patients.

Methods. Data were obtained from the Medicare fee-for-service claims database from 2010 to 2013. RA Medicare patients were identically matched with Medicare patients without RA (controls) based on demographics. Bivariate analyses were conducted to examine differences between cohorts for comorbidities, HCRU and costs. A generalized linear model was used to test relationships between patient-level characteristics, HCRU and costs.

Results. The study population included 115 867 RA patients and …

An Information Theory Approach To Hypothesis Testing In Criminological Research, Gohar A. Petrossian, Mike Maxfield

Publications and Research

Background: This research demonstrates how the Akaike information criterion (AIC) can be an alternative to null hypothesis significance testing in selecting best fitting models. It presents an example to illustrate how AIC can be used in this way.

Methods: Using data from Milwaukee, Wisconsin, we test models of place-based predictor variables on street robbery and commercial robbery. We build models to balance explanatory power and parsimony. Measures include the presence of different kinds of businesses, together with selected age groups and social disadvantage.

Results: Models including place-based measures of land use emerged as the best models among the set of …

Integrating Multiple Instructional Mediums To Teach Critical Literacy With The Adult Linguistically Diverse Learners, Kaemanje Thomas

Publications and Research

Critical reading is the apex of tertiary education and the chief focus in higher education courses as they prepare adults for the workforce. Without significant improvements in academic preparation and support, many linguistically diverse [LD] students will have higher drop out rates in their first year of college. Developmental reading instruction practices are designed to emphasize moving the first-year LD students from sub-par reading levels towards the application and development of critical reading skills, as demanded by their college courses. Many community colleges across the United States prepare assessments tests in reading and mathematics for most, if not all, newly …

Cooperative Standing-Horizontalstanding Reentrant Transition For Numerous Solid Particles Under External Vibration, Satoshi Takatori, Hikari Baba, Takatoshi Ichino, Chwen-Yang Shew, Kenichi Yoshikawa

Publications and Research

We report the collective behavior of numerous plastic bolt-like particles exhibiting one of two distinct states, either standing stationary or horizontal accompanied by tumbling motion, when placed on a horizontal plate undergoing sinusoidal vertical vibration. Experimentally, we prepared an initial state in which all of the particles were standing except for a single particle that was placed at the center of the plate. Under continuous vertical vibration, the initially horizontal particle triggers neighboring particles to fall over into a horizontal state through tumbling-induced collision, and this effect gradually spreads to all of the particles, i.e., the number of horizontal particles …

Numbers Are Just Not Enough: A Critical Analysis Of Race, Gender, And Sexuality In Elementary And Middle School Health Textbooks, Sherry L. Deckman, Ellie Fitts Fulmer, Keely Kirby, Katharine Hoover, Abena S. Mackall

Publications and Research

Textbooks are a multimillion dollar publishing business in the United States. Even as 21st-century classrooms become more multimodal, digital and hardcopy textbooks remain a key feature of American education. Consequently, classroom textbooks have been shown to control knowledge dissemination across the content areas. In particular, health texts have been uniquely shown to communicate values that validate or marginalize students and encourage healthy or harmful activity. Thus,what textbook makers choose to include as worthy of study, and how they portray various groups of people with regard to race, gender, and sexuality has societal implications. Employing quantitative and qualitative content analysis methods, …

Communication Based Control For Dc Microgrids, Mahmoud S. Saleh, Yusef Esa, Ahmed Mohamed

Publications and Research

Centralized communication-based control is one of the main methods that can be implemented to achieve autonomous advanced energy management capabilities in DC microgrids. However, its major limitation is the fact that communication bandwidth and computation resources are limited in practical applications. This can be often improved by avoiding redundant communications and complex computations. In this paper, an autonomous communication-based hybrid state/event driven control scheme is proposed. This control scheme is hierarchical and heuristic, such that on the primary control level, it encompasses state-driven local controllers, and on the secondary control level, an event-driven MG centralized controller (MGCC) is used. This …

Component Tree Analysis Of Cystovirus Φ6 Nucleocapsid Cryo-Em Single Particle Reconstructions, Lucas Oliveira, Ze Ye, Al Katz, Alexandra Alimova, Hui Wei, Gabor T. Herman, Paul Gottlieb

Publications and Research

The 3-dimensional structure of the nucleocapsid (NC) of bacteriophage φ6 is described utilizing component tree analysis, a topological and geometric image descriptor. The component trees are derived from density maps of cryo-electron microscopy single particle reconstructions. Analysis determines position and occupancy of structure elements responsible for RNA packaging and transcription. Occupancy of the hexameric nucleotide triphosphorylase (P4) and RNA polymerase (P2) are found to be essentially complete in the NC. The P8 protein lattice likely fixes P4 and P2 in place during maturation. We propose that the viral procapsid (PC) is a dynamic structural intermediate where the P4 and P2 …
