Investigation Of The Structure Of The Few Body Kaonic Nuclei Using The Method Of Hyperspherical Functions In Momentum Space, Roman Ya. Kezerashvili, Shalva M. Tsiklauri

Publications and Research

The kaonic clusters KNN and KNNN are studied within the method of hyperspherical functions in the momentum representation. Binding energies and widths of three- and four-body nuclear quasibound states are calculated by employing realistic NN potentials and the energy dependent chiral KN interaction, as well as a phenomenological KN potential. The comparison of the results of calculations obtained in the framework of the variational method, Faddeev, Faddeev-Yakubovsky equations, and method of hyperspherical functions in configuration space are discussed.

Teaching An Electrical Circuits Course Using A Virtual Lab, Md Zahidur Rahman

Publications and Research

This paper describes designing and implementing a scholarship of teaching and learning (SoTL) study in a basic electrical circuits course at LaGuardia Community College. Inspired by my understanding of Shulmans (2005) concept of signature pedagogy and Mazurs (2009) emphasis on student-centered approaches, and aware that our students did not always understand the electrical theory concepts presented in class, I decided to change my pedagogy. We explain our efforts to train our students to think as engineers, first by making them more visible and accountable in the classroom, and second, by offering them hands-on practice through the use of Multisim, a …

Evolutionary Algorithm Based Approach For Modeling Autonomously Trading Agents, Anil Yaman, Stephen Lucci, Izidor Gertner

Publications and Research

The autonomously trading agents described in this paper produce a decision to act such as: buy, sell or hold, based on the input data. In this work, we have simulated autonomously trading agents using the Echo State Network (ESNs) model. We generate a collection of trading agents that use different trading strategies using Evolutionary Programming (EP). The agents are tested on EUR/ USD real market data. The main goal of this study is to test the overall performance of this collection of agents when they are active simultaneously. Simulation results show that using different agents concurrently outperform a single agent …

Algebraic Formulation Of Hadronic Supersymmetry Based On Octonions: New Mass Formulas And Further Applications, Sultan Catto, Yasemin Gürcan, Amish Khalfan, Levent Kurt

Publications and Research

A special treatment based on the highest division algebra, that of octonions and their split algebraic formulation is developed for the description of diquark states made up of two quark pairs. We describe symmetry properties of mesons and baryons through such formulation and derive mass formulae relating π, ρ, N and Δ trajectories showing an incredible agreement with experiments. We also comment on formation of diquark-antidiquark as well as pentaquark states and point the way toward applications into multiquark formulations expected to be seen at upcoming CERN experiments. A discussion on relationship of our work to flux bag models, string …

Generalized Least-Squares Regressions Iii: Further Theory And Classification, Nataniel Greene

Publications and Research

This paper continues the work of this series with two results. The first is an exponential equivalence theorem which states that every generalized least-squares regression line can be generated by an equivalent exponential regression. It follows that every generalized least-squares line has an effective normalized exponential parameter between 0 and 1 which classifies the line on the spectrum between ordinary least-squares and the extremal line for a given set of data. The second result is the presentation of fundamental formulas for the generalized least-squares slope and y-intercept.

The results indicate that a central core supporting a national experiment can help overcome local obstacles.

Variance Predicts Salience In Central Sensory Processing, Ann M. Hermundstad, John J. Briguglio, Mary M. Conte, Jonathan D. Victor, Vijay Balasubramanian, Gašper Tkačik

Publications and Research

Information processing in the sensory periphery is shaped by natural stimulus statistics. In the periphery, a transmission bottleneck constrains performance; thus efficient coding implies that natural signal components with a predictably wider range should be compressed. In a different regime—when sampling limitations constrain performance—efficient coding implies that more resources should be allocated to informative features that are more variable. We propose that this regime is relevant for sensory cortex when it extracts complex features from limited numbers of sensory samples. To test this prediction, we use central visual processing as a model: we show that visual sensitivity for local multi-point …

Sensitivity Of Orbiting Jem-Euso To Large-Scale Cosmic-Ray Anisotropies, Peter B. Denton, Luis A. Anchordoqui, Andreas A. Berlind, Matthew Richardson, Thomas J. Weiler

Publications and Research

The two main advantages of space-based observation of extreme-energy (& 1019 eV) cosmic-rays (EECRs) over ground-based observatories are the increased field of view, and the all- sky coverage with nearly uniform systematics of an orbiting observatory. The former guarantees increased statistics, whereas the latter enables a partitioning of the sky into spherical harmonics. We have begun an investigation, using the spherical harmonic technique, of the reach of JEM- EUSO into potential anisotropies in the extreme-energy cosmic-ray sky-map. The technique is explained here, and simulations are presented. The discovery of anisotropies would help to identify the long-sought origin of EECRs.

Brownfield Action: Dissemination Of A Sencer Model Curriculum And The Creation Of A Collaborative Stem Education Network, Peter Bower, Ryan Kelsey, Joseph Liddicoat, Doug M. Thompson, Angelo Lampousis, Bret Bennington, Bess Greenbaum Seewald, Arthur D. Kney, Saugata Datta, Lawrence D. Lemke, Briane Sorice Miccio, Tamara Graham

Publications and Research

Brownfield Action (BA) is a web-based environmental site assessment (ESA) simulation in which students form geotechnical consulting companies and work together to solve problems in environmental forensics. Developed at Barnard College with the Columbia Center for New Media Teaching and Learning, BA has been disseminated to ten colleges, universities, and high schools, resulting in a collaborative network of educators. The experiences of current users are presented describing how they have incorporated the BA curriculum into their courses, as well as how BA affected teaching and learning. The experiences demonstrate that BA can be used in whole or in part, is …

Teaching Standards In Environmental Site Assessments, Angelo Lampousis

Publications and Research

Since 2010, the Department of Earth and Atmospheric Sciences of City College of New York (CCNY) has successfully implemented a two-semester sequence course entitled Phase I and Phase II Environmental Site Assessments. From the very beginning of this effort, a total of ten standards per semester were used as mandatory reference material. Based on this experience, several practical ideas emerge as successful means of integrating standards into an academic curriculum.

Relativistic Particle And Relativistic Fluids: Magnetic Moment And Spin-Orbit Interactions, V. Parameswaran Nair, Dimitra Karabali

Publications and Research

We consider relativistic charged particle dynamics and relativistic magnetohydrodynamics using symplectic structures and actions given in terms of co-adjoint orbits of the Poincare group. The particle case is meant to clarify some points such as how minimal coupling (as defined in text) leads to a gyromagnetic ratio g = 2, and to set the stage for fluid dynamics. The general group-theoretic framework is further explained and is then used to set up Abelian magnetohydrodynamics including spin effects. An interesting new physical effect is precession of spin density induced by gradients in pressure and energy density. The Euler equation (the dynamics …

Terminal Summation: Extending The Concept Of Convergence, Max Tran, Ayalur Krishnan

Publications and Research

This paper presents an atypical method for summing divergent series, and provides a sum for the divergent series log(n). We use an idea of T.E. Phipps, called Terminal Summation, which uses asymptotic analysis to assign a value to divergent series. The method associates a series to an appropriate difference equations having boundary conditions at infinity, and solves the difference equations which then provide a value for the original series. We point out connections between Phipps' method, the Euler-MacLaurin sum formula, the Ramanujan sum and other traditional methods for summing divergent series.

Idiots Savants, Retarded Savants, Talented Aments, Mono-Savants, Autistic Savants, Just Plain Savants, People With Savant Syndrome, And Autistic People Who Are Good At Things: A View From Disability Studies, Joseph N. Straus

Publications and Research

People identified as idiot savants have long comprised an identifiable group (a high level of skill in the context of perceived mental deficiency) whose story has mostly been told by psychiatrists and psychologists within a medicalized model of disability that assumes deficiency and seeks remediation and normalization. More recently, people identified as savants have become common figures of literary and cinematic representation. Both of these narrative frames have enfreaked them as alien Others, whose gifts and disabilities place them outside the normal run of human intelligence and creativity. With a focus on music, this article tries to see through these …

Does U.S. Macroeconomic News Make Emerging Financial Markets Riskier?, Esin Cakan, Nadia Doytch, Kamal P. Upadhyaya

Publications and Research

This study analyzes the impacts of US macroeconomic announcement surprises on the volatility of twelve emerging stock markets by employing asymmetric GJR-GARCH model. The model includes both positive and negative surprises about inflation and unemployment rate announcements in the U.S. We find that volatility shocks are persistent and asymmetric. Asymmetric volatility increases with bad news on US inflation in five out of the twelve countries studied and it increases with a bad news on U.S. unemployment in four out of twelve countries. Asymmetric volatility decreases with good news about US employment situation in eight countries out of twelve countries. Such …

Perception Of Childhood Obesity And Support For Prevention Policies Among Latinos And Whites, Douglas M. Puricelli Purin, Leah Frerichs, Sergio Costa, Amelie G. Ramirez, Terry T.-K. Huang

Publications and Research

A cross-sectional survey was administered to Latino and White residents of Omaha, NE, to assess perception of the childhood obesity problem, attribution of responsibility, and support for obesity-related policies. The sample included 40.8% () Latinos and 59.2% () Whites. Among Latinos, 25% did not see childhood obesity as a problem, compared to 6% of Whites (). This difference persisted after adjusting for age, gender, and education level (odds ratio (OR) 2.10, 95% confidence interval (CI) 1.07–4.14). Latinos were more likely to agree that government was responsible for addressing childhood obesity compared to Whites (OR 2.81, 95% CI 1.82–4.35). Higher support …

Spatial Gaussian Markov Random Fields: Modelling, Applications And Efficient Computations, Yu Ryan Yue, Xiao-Feng Wang

Publications and Research

A powerful modelling tool for spatial data is the framework of Gaussian Markov random fields (GMRFs), which are discrete domain Gaussian random fields equipped with a Markov property. GMRFs allow us to combine the analytical results for the Gaussian distribution as well as Markov properties, thus allow for the development of computationally efficient algorithms. Here we briefly review popular spatial GMRFs, show how to construct them, and outline their recent developments and possible future work.

An African-Centered Approach To Land Education, Salvotore Engel-Dimauro, Karanja Keita Carroll

Publications and Research

Approaches to environmental education which are engaging with place and critical pedagogy have not yet broadly engaged with the African world and insights from Africana Studies and Geography. An African-centered approach facilitates people's reconnection to places and ecosystems in ways that do not reduce places to objects of conquest and things to be exploited for profitability and individual gain. Such an approach offers effective critiques of settler coloniser perspectives on the environment and deeper understandings of the relationship between worldview and ecologically sensitised education. Through examples from Africana Studies and Geography, this article provides an introduction to how an African-centered …
