Tuning The Thermodynamic, Optical, And Rheological Properties Of Thermoresponsive Polymer Solutions Via Silica Nanoparticle Shape And Concentration, Christopher A P Neal, Valeria León, Michelle C. Quan, Nondumiso O. Chibambo, Michelle A. Calabrese

Mechanical Engineering Faculty Publications

Hypothesis

The shape and quantity of hydrophilic silica nanoparticles (NPs) can be used to tune the microstructure, rheology, and stability of phase-separating polymer solutions. In thermoresponsive polymer systems, silica nanospheres are well-studied whereas anisotropic NPs have little literature precedent. Here, we hypothesize that NP shape and concentration lower the onset of rheological and turbidimetric separation of aqueous poly(N-isopropyl acrylamide) (PNIPAM) solutions.

Experiments

Differential scanning calorimetry (DSC), Fourier-transform infrared spectroscopy (FTIR), turbidimetry, and oscillatory rheology are utilized to examine interactions between NPs, PNIPAM, and water and to track changes in phase separation and mechanical properties due to NP concentration and shape. …

A New Classification Network For Diagnosing Alzheimer’S Disease In Class-Imbalance Mri Datasets, Ziyang Chen, Zhuowei Wang, Meng Zhao, Qin Zhao, Xuehu Liang, Jiajian Li, Xiaoyu Song

Electrical and Computer Engineering Faculty Publications and Presentations

Automatic identification of Alzheimer’s Disease (AD) through magnetic resonance imaging (MRI) data can eectively assist to doctors diagnose and treat Alzheimer’s. Current methods improve the accuracy of AD recognition, but they are insufficient to address the challenge of small interclass and large intraclass dierences. Some studies attempt to embed patch-level structure in neural networks which enhance pathologic details, but the enormous size and time complexity render these methods unfavorable. Furthermore, several self-attention mechanisms fail to provide contextual information to represent discriminative regions, which limits the performance of these classifiers. In addition, the current loss function is adversely aected by outliers …

The Effects Of False Heartbeat Feedback On Moral Judgment, Scott Koenig

Dissertations, Theses, and Capstone Projects

Research on human morality is at a crossroads, with one side claiming that moral judgment is the result of rational inference and the other side claiming that it is the result of emotion-laden intuition. This study investigated whether emotion drives moral judgment by manipulating a core component of the experience of emotion: physiological arousal. The sample consisted of 77 undergraduate students at Brooklyn College (57% women, 43% men; mean age = 20.1). One group of participants was led to believe their heart was beating quickly, and another group slowly, while they read and evaluated a series of text vignettes depicting …

Carceral Calisthenics: Physical Culture In The Hood, Albert L. De La Tierra

Dissertations, Theses, and Capstone Projects

How do racialized men who reside in structurally marginalized locales that are putatively regarded as “the hood” navigate and manage their social conditions? This dissertation sheds light on this question by treating “street workout,” a physical culture centered around calisthenics exercises performed in public space, as an empirical site for generating a situated understanding of how some Black men assert themselves in social space at the same time that they are asserted upon by social forces. Taking an ethico-onto-epistem-ological stance that refuses the colonial gaze (a ubiquitously employed optic that dehumanizes racialized people), this dissertation asks: (1) What embodied practices …

Essays On Machine Learning Methods In Economics, Mani Bayani

Dissertations, Theses, and Capstone Projects

This dissertation consists of three chapters on machine learning modeling in economics. Chapter 1 - Robust PCA Synthetic Control: In this chapter, I propose an algorithm for comparative studies called robust PCA synthetic control. My algorithm builds on the synthetic control model of Abadie et al., 2015 and the robust synthetic control model of Amjad et al., 2018. I apply all three methods (robust PCA synthetic control, synthetic control, and robust synthetic control) to answer the hypothetical question, what would have been the per capita GDP of West Germany if it had not reunified with East Germany in 1990? I …

Essays On Impacts Of Women Empowerment On The Health Outcomes Of Children, Sagnik Das

Dissertations, Theses, and Capstone Projects

Chapter 1: Taking cognizance of the lack of representation of women in politics, the Indian government in 1993, enacted the 73rd constitutional amendment which led to a sudden increase in the representation of women in the local governments. Exploiting the exogenous variation in the timing of implementation of the 73rd amendment across the states, I study the spillover effects of this mandated empowerment of women on the health outcomes of children by using nationally representative survey data and employing a difference-in-difference estimation strategy. In this study, I find evidence of a positive impact of mandated women empowerment on the survival …

Topological Shadow Of Higher-Order Topological Phases And Non-Hermitian Phases Protected By Generalized Rotational Symmetry, Kai Chen

Dissertations, Theses, and Capstone Projects

Topological phenomena in condensed matter physics have been investigated intensively in the past decades since the discovery of the integer quantum Hall effect (IQHE). For the IQHE, the energy band can be characterized by its topological invariants (Chern number or TKNN invariant), which relates to the quantized Hall conductance directly. Later, this expression was recognized as the first Chern class of a U(1) principal fiber bundle on a torus, where the fibers and torus correspond respectively to the magnetic Bloch waves and the magnetic Brillouin zone. And then, the discoveries of time-reversal symmetric topological insulators in two and three dimensions …

Growth, Optimization, And Characterization Of Topological Insulator Nanostructures By Molecular Beam Epitaxy, Ido Levy

Dissertations, Theses, and Capstone Projects

Topological insulators (TIs) have been the subject of much research since their discovery in 2009. The unique band structure of the TIs makes them attractive in research of exotic physical phenomena, such as the realization of the quantum anomalous Hall effect, as well as novel applications, including quantum computing, spintronics, and more. From a crystal growth perspective, their van-der-Waals structure also provides new opportunities, for example, by enabling the growth on a large selection of substrates. This thesis presents the growth of three-dimensional TI layers, heterostructures and magnetic TIs by molecular beam epitaxy (MBE). First, we show the improvement of …

Graphic Novels In The Foreign Language Classroom: Teaching Central American History In The Target Language, Vanessa Elizabeth Guzmán

Dissertations, Theses, and Capstone Projects

Graphic novels are becoming increasingly helpful in the foreign language classroom. As a Spanish teacher in the Bronx, I have introduced numerous graphic novels into my lessons. Some graphic novels include familiar characters and are presented in a translated work, while others are graphic novels that were originally printed in Spanish. I have witnessed the advantages of using graphic novels in my classroom as the illustrations provide my readers with context clues to better understand the reading. I have also found some graphic novels that focus on historical events in Latin America but these works were either written entirely in …

A Study Of Pressure Probe Response In Steady And Unsteady Flows, Michael T. Charonnat

Master's Theses

The objective of this thesis is two-fold: to analyze the directional calibration of a 3-hole probe in steady flow and to develop a method for the interpretation of measurements recorded with a novel, fast-response Pitot-type probe in unsteady, turbulent flow. Calibration data for the 3-hole probe’s two side ports was taken in the steady, non-turbulent region of a free jet and was evaluated for symmetry. In addition, data that was recorded using one side port in two independent calibration runs was compared to study repeatability. Misalignment was found between the nominally symmetric data sets, which may be the result of …

Water Insecurity And Gender-Based Violence: A Global Review Of The Evidence, Paula S. Tallman, Shalean Collins, Gabriela Salmon-Mulanovich, Binahayati Rusyidi, Aman Kothadia, Stroma Cole

Anthropology: Faculty Publications and Other Works

We reviewed the existing literature documenting the association between water insecurity and gender-based violence to (1) describe the characteristics and contexts of available studies, and (2) identify and classify documented gender-based violence across domains of water insecurity (access, affordability, adequacy, reliability, and safety). 18 peer-reviewed articles mentioned associations between water insecurity and gender-based violence. All studies were conducted in sub-Saharan Africa and South Asia and were published in English. The most common manifestation of the relationship between water insecurity and gender-based violence was an increased risk of sexual and physical violence for women who walked long distances to access water. …

The Asymmetric Effects Of External Debt On Economic Growth In Selected Mena Countries: Some Insights From A Panel Quantile Regression, Mahmoud Haddad, Refk Selmi, Shawkat Hammoudeh

Topics in Middle Eastern and North African Economies

The increased level of debt is a major risk for the financial stability and questions the ability of countries to balance fiscal vulnerabilities with development goals. With the rising debt wave and additional pressures induced by the pandemic and the Russian/Ukrainian war on sources of development finance, this study uses a panel quantile regression to re-examine the asymmetric relationship between the external debt and economic growth in six highly indebted MENA countries, namely, Bahrain, Egypt, Jordan, Lebanon, Morocco and Tunisia over the period 2006-2019. The outcomes support the main hypothesis that high debt reduces economic growth, yet this effect seems …

Physics: Faculty Publications and Other Works

The reconstruction of event-level information, such as the direction or energy of a neutrino interacting in IceCube DeepCore, is a crucial ingredient to many physics analyses. Algorithms to extract this high level information from the detector’s raw data have been successfully developed and used for high energy events. In this work, we address unique challenges associated with the reconstruction of lower energy events in the range of a few to hundreds of GeV and present two separate, state-of-the-art algorithms. One algorithm focuses on the fast directional reconstruction of events based on unscattered light. The second algorithm is a likelihood-based multipurpose …
