Title of Talk: Five Types of Discrete Mathematics Problems that Should Be Part of Every College Student’s Quantitative Literacy Expectations
Abstract: Quantitative literacy requirements (aka general education math requirements) should include some discrete mathematics, in addition to the most commonly included areas–algebra, statistics, and probability. In particular, in this talk I propose that all college students should have some understanding of five discrete mathematics problem types – enumeration, sequential change, networks, fair decision making, and information processing. This proposal has implications for developmental math courses as well as quantitative literacy and math for liberal arts courses. I will present some elaboration and examples.

Title of Talk: variable selection in high dimensional regression
Abstract: My research work studies statistical regression models for data sets with a small sample but huge number of variables. For example, we may wish to study the same 5000 genes in only 200 individuals with the goal of predicting whether they will develop a certain rare cancer. A classical linear regression for the cancer outcome in terms of the 5000 genes does not work with only 200 data points because the associated linear equations are not full rank. We might choose 200 of the genes and do a regression, but there are over 10^363 such choices. My work uses "penalty functions" add to the linear equations which will make the problem solvable. Theoretically, we can show that the result have the "oracle" property which means it will give us the baseline true model with probability going to 1.

Title of Talk: Anti-Van der Waerden number of 3-term arithmetic progression
Abstract: A set is rainbow if each element of the set is a di erent color. The anti-van der Waerden number of the integers from 1 to n, denoted by aw([n]; k), is the least positive integer r such that every exact r-coloring of [n] contains a rainbow k-term arithmetic progression. The exact value of the anti-van der Waerden number of the integers where k = 3 is given by aw([n]; 3) = dlog3 ne+2. The anti-van der Waerden number can also be de ned on graphs, where aw(G; k) is the least number of colors such that every coloring contains a rainbow k-term arithmetic progression. Bounds on the anti-van der Wareden number of graphs have been established and exact values are known for certain families of graphs. Keywords: Rainbow, r

Title of Talk: Fractal Sequence Analysis and Creation of Art and Music
Abstract: For my seminar project, I have been analyzing fractal sequences and using them to create images and to modify musical compositions. A fractal sequence has a pattern that repeats at all scales. One well-known sequence is the Thue-Morse Sequence. This sequence is created by translating the positive integers into base(2) and then adding the digits for each number and taking mod(2) of the result. This forms a pattern of zeroes and ones that continues infinitely. If consecutive numbers are put into groups of two, a unique characteristic about this sequence is revealed. When the first number of every set is kept and the second removed, the remaining numbers create the original pattern. I have shown that translating the integers into base(n) and summing digits mod(n) elicits a similar pattern. I will show how these sequences can then be translated into art and music and analyze the results.

Title of Talk: Promoting Out-of-Class Engagement Using Piazza
Abstract: This talk is aimed at sharing many lessons learned regarding how to promote quality out-of-class engagement. We discuss implementation of Piazza and online quizzes in a flipped "Introduction to Proofs" course taught over six terms across two Universities. We view this course as a communications course. Our students need to learn how to communicate Mathematics informally and formally both verbally and in written form. We have found the flipped structure allows for ample time for our students to learn how to communicate Mathematics informally as they discuss the various problems with classmates. We have also found that increasing the informal communication skills of our students usually doesn't correspond to an increase in their formal writing. We use Piazza as a way of providing massive amounts of formative assessment aimed at perfecting their formal writing skills and we use online quizzes both as reading quizzes and as flash cards to help students memorize and understand the definitions in the course.

Title of Talk: Characterizing Isometries: A Long Running Undergraduate Research Project
Abstract: In 2010, my adviser Aaron Luttman began an undergraduate research project with an honors student at Clarkson University. The goal was to investigate a decomposition for isometries between normed vector spaces; specifically, to prove that the domain of the isometry had to be the direct sum of ``nice'' subspaces. The project ended in 2011 when my adviser (and the student) left academia. I revived the project in 2015 with an honors student here at Iowa State University, and while significant progress was made, we did not fully resolve it. This semester, I am approaching the problem again with a new student. We'll talk about the ins, outs, and what-have-yous of the project, where we currently stand, and the plan going forward.

Title of Talk: Connections Between Mathematics and Biology
Abstract: Dr. Rita Colwell, a research microbiologist and former Director of the National Science Foundation, regards the mathematical sciences as the backbone for US Scientific and Engineering research. Many scholars see the next few decades as a time of intensive progress in the biological sciences. Dr. Colwell sees mathematics as being an integral part of the progress in biology, not a traditional view, but a forward looking one. In this talk, Carl Cowen will outline some of the research areas in the emerging collaborations between mathematical and biological scientists. In addition, Cowen, who began his study of the mathematics of neuroscience in 2002-03 at the Mathematical Biosciences Institute at Ohio State University, and who worked in 2003-04 as a junior post-doc in the lab of Prof. Christie Sahley in the Purdue University Biology Department, will illustrate the connection between mathematics and neuroscience with a discussion of the Pulfrich phenomenon, an experiment that helps illuminate how the brain processes visual images. There are few mathematical or biological prerequisites for this discussion.

Title of Talk: Rearranging the Alternating Harmonic Series
Abstract: The commutative property of addition is so familiar to all of us as school children that it comes as a shock to those studying college level mathematics that NOT all 'natural extensions' of the law are true! One of the first instances that we see the failure of an extended commutative law of addition is in infinite series. Often in the introduction to infinite series in calculus, one sees Riemann's Theorem: A conditionally convergent series can be rearranged to sum to any number. Unfortunately, the usual proof of this theorem does not indicate what the sum of a given rearrangement is. In this talk, we will examine the best known conditionally convergent series, the alternating harmonic series, and show how to find the sum of any rearrangement in which the positive terms and the negative terms are each in their usual order.

Title of Talk: Regional Communities of Practice around Inquiry-Based Learning
Abstract: What began as a small group of professors gathering to discuss implementation of Inquiry-Based Learning (IBL) in our classes has developed into a strong regional community of practice. The Upstate New York IBL consortium was created in 2014 with a mission to create, grow, and maintain a community of instructors across the region. We will discuss how the consortium formed organically, the way that it operates, and several efforts to replicate it in other regions. Suggestions will be provided for creating your own regional community of practice for supporting the adoption and enhancement of active learning techniques.

Title of Talk: Digitalization in the signal processing
Abstract: In real life when we store and transmit analog audio or video signals, we first obtain a digital representation of the signal. This process is called Digitalization or Analog-to-Digital (A/D) conversion and consists of two steps: sampling and quantization. In the "sampling" step we restrict time to a discrete sample of the continuous times. In the "quantization" step we discretize the real values of the time-discrete sample of the first step. We will discuss different quantization methods based on binary expansion or Beta-expansion and compare their "accuracy." "Accuracy" means that we can re-construct a good approximation of the original signal from its digitalization. Or "can you hear me now?"
