Tumor Dynamics Under Immunotherapy: A Time-Delay Revised Predator-Prey Model, Emma A. Turian Nov 2019

Tumor Dynamics Under Immunotherapy: A Time-Delay Revised Predator-Prey Model, Emma A. Turian

Faculty Research and Creative Activities Symposium

Cancer remains a leading cause of death worldwide and traditional treatments such as surgical resection, chemotherapy, and radiotherapy may have limited benefits depending on the type of cancer and the stage at which it is diagnosed. Immunity is the state of protection against foreign pathogens or substances (i.e., antigens). Recent research into novel approaches to treatment has suggested that immunotherapy, which aims to optimize the body’s own natural responses to combating disease through various mechanisms, may be a promising strategy that can improve prognosis for certain cancer types that are refractory to other treatment options. Quantitative models simulating the dynamics …


Arsenoplatins - Potent Anticancer Agents Against Triple-Negative Breast Cancer, Denana Miodragovic Nov 2019

Arsenoplatins - Potent Anticancer Agents Against Triple-Negative Breast Cancer, Denana Miodragovic

Faculty Research and Creative Activities Symposium

Triple-negative breast cancer (TNBC) is a more aggressive breast cancer with a poorer prognosis than other types of breast cancer. TNBC mortality is 42% higher in African American women compared to other American women, which is one of the most significant examples of racial disparity in oncology. TNBC does not express the common receptors estrogen and progesterone or the human epidermal growth factor receptor 2 (HER2), making targeted hormone therapies ineffective. Thus, there is an urgent medical need for the development of novel potential drug candidates for TNBC. In clinics, platinum-based regimes provide overall survival advantages for TNBC patients compared …


Internet Searching Behaviors Of Low Literacy Breast Cancer Survivors, Francisco D. Iacobelli, Ginger L. Dragon, Giselle Mazur, Judy Guitelman Nov 2019

Internet Searching Behaviors Of Low Literacy Breast Cancer Survivors, Francisco D. Iacobelli, Ginger L. Dragon, Giselle Mazur, Judy Guitelman

Faculty Research and Creative Activities Symposium

Internet searching is a popular tool for patients to find health-related information. However, low literacy individuals are at a disadvantage with respect to their ability to evaluate online health information. When using common web search engines to find health information, behaviors such as misspelling, misappropriation of words and incomplete search queries can result in inadequate results and misleading information. The goal of this research is to understand the search strategies and common mistakes that low-literacy Latina breast cancer survivors exhibit when searching for information online in order to inform future information seeking interfaces. To explore search behaviors online we asked …


Newton’S Iteration At Nonisoated Solutions, Zhonggang Zeng Nov 2019

Newton’S Iteration At Nonisoated Solutions, Zhonggang Zeng

Faculty Research and Creative Activities Symposium

Newton’s iteration is arguably the most important and fundamental method for solving systems of nonlinear equations with a long and fascinating history. Its local quadratic convergence to isolated nonsingular solutions is well documented in the literature. It is also well-known that the iteration loses its quadratic rate of convergence, if it applies and converges at all, to nonisolated solutions with a dismal attainable accuracy in numerical computation. Even though solving systems of nonlinear equations is a standard topic in textbooks of numerical analysis, the elaboration has always been limited to isolated solutions. Models with nonisolated solutions frequently arise in applications. …


On The Apparent Attractive Interaction Between Colloidal Particles Of Like Charge, Stefan Tsonchev Nov 2019

On The Apparent Attractive Interaction Between Colloidal Particles Of Like Charge, Stefan Tsonchev

Faculty Research and Creative Activities Symposium

A new attractive force between colloidal particles of like charge has been discovered. This force is of entropic depletion origin, and is exhibited between colloidal particles in electrolyte solution. The attractive potential associated with this force is a function of the electrolyte concentration, and can have a minimum up to the order of -10 kT deep for certain parameters of the system. Implications of the force to various systems of interest will be discussed.


Monitoring The Breakdown Of Plastic Materials Under Ultraviolet And Visible Light, Samantha Brown-Xu Nov 2019

Monitoring The Breakdown Of Plastic Materials Under Ultraviolet And Visible Light, Samantha Brown-Xu

Faculty Research and Creative Activities Symposium

The accumulation of plastic waste in landfills and especially in water systems is a pressing environmental concern. Every year, roughly 8 million tons of plastic waste escapes into the oceans, which over time can then break down into microplastics, less than a quarter inch in size, that are consumed by ocean wildlife. The plastic degradation can occur by mechanical means, but energy absorbed from sunlight is also involved in the breakdown of plastic materials. If the efficiency of this degradation was increased, solar energy could be used to eliminate plastic waste and regenerate fuels or chemical feedstocks. In this study, …


Integrating Problem Solving, Coding, Mathematics, And Pedagogy, John F. Erickson Nov 2019

Integrating Problem Solving, Coding, Mathematics, And Pedagogy, John F. Erickson

Faculty Research and Creative Activities Symposium

We present a case study illustrating an integrated approach to the teaching of problem solving, computation, and mathematics. This approach combines ideas from Polya, Ross, and Moore about mathematical pedagogy with a heavy dose of computer assisted calculation in the spirit of experimental mathematics facilitated by the rapid prototyping environment of Mathematica which is ideal for an exploratory approach to learning. Essentially, students learn math and programming the same way mathematicians do research and we believe that this can scale all the way from grammar school to graduate school. To be more specific, we start with an elementary recreational math …


Guiding Us Throughout A Sea Of Data - A Survey On Recommender Systems And Its Privacy Challenges, Xiwei Wang, Marcelo O. Sztainberg Nov 2019

Guiding Us Throughout A Sea Of Data - A Survey On Recommender Systems And Its Privacy Challenges, Xiwei Wang, Marcelo O. Sztainberg

Faculty Research and Creative Activities Symposium

Over the past decades, the Internet has served as the backbone connecting people to others, places and things. With the sheer volume of information generated everyday, people can feel overwhelmed when having to make a selection among the multiple options that normally come up after a search or application request. For example, when searching for news articles regarding a particular topic, the search engine will present a number of results to you. When looking for some product on shopping websites, there are usually several pages of results that match the keywords. It can be very challenging for people to find …

2019 Student Center For Science Engagement Research Symposium Program, Student Center For Science Engagement Sep 2019

2019 Student Center For Science Engagement Research Symposium Program, Student Center For Science Engagement

Student Center for Science Engagement Research Symposium

It gives me great pleasure to welcome you to the 11th Annual SCSE Research Symposium. In just over a decade, undergraduate summer research in the sciences at Northeastern Illinois University has grown from a few groups of students working with faculty mentors within their departments, to a robust, structured summer research program with dozens of students working with faculty across the STEM disciplines at NEIU. The presentations at the symposium today will give you all an appreciation of the breadth and depth of the scientific questions that our students have been investigating all summer. To our students presenting their work …
