Women Advancing Arizona Mathematics
Susanna Fishel, School of Mathematical and Statistical Sciences, Arizona State University, will speak on “Enumeration of strong, standard, starred tableaux” at 5:00 PM in Math 501. (Refreshments will be served.)
Schur functions are a basis for the ring of symmetric functions, one with many important algebraic and combinatorial properties. k-Schur functions are a basis for a certain subring of that ring and are turning out to be just as interesting. Many results involving Schur functions have analogues involving k-Schur functions. Standard strong marked tableaux play a role for k-Schur functions similar to the role standard Young tableaux play for Schur functions. I will discuss results and conjectures toward an analogue of the hook length formula. This is joint work with Matjaz Konvalinka.

Analysis, Dynamics, and Applications Seminar
Alexander Young, Program in Applied Mathematics, The University of Arizona, will speak on “"A statistical mechanics approach to modeling collective motion" ” at 12:30 PM in Math 402.
Collective motion is a ubiquitous phenomenon in nature with a variety of examples over many orders of magnitude in size. The development of models which capture these dynamics presents interesting mathematical challenges.In this talk, I'll review a statistical mechanics approach used by Bertin et al. for a system of interacting particles wherein a hydrodynamic equation is developed in a Boltzmann framework.Finally, I'll discuss extensions of this work including numerical a study of the hydrodynamic equation and effects of altering the manner in which particles interact.
SIAM Student Chapter Meeting
Stacey Tannenbaum, Astellas Pharma Global Development , will speak on “Pharmacometrics: Applied Mathematics in the Pharmaceutical Industry ” at 3:30 PM in Math 401N.
Pharmacometrics uses mathematical and statistical models based on pharmacology, physiology and disease for quantitative analysis of interactions between drugs and patients. Pharmacometrics is used in the pharmaceutical industry to optimize clinical study designs, make efficient dose regimen selections, define intersubject variabity towards individualizing drug therapy, and understand pathways of disease to inform drug discovery. I will introduce the principles of Pharmacometrics (specifically, my area of expertise, Pharmacokinetic-Pharmacodynamic modeling) and share a case study in which PK-PD was used to optimize dosing and expand the use of a marketed drug to a patient population with an unmet medical need.
Mathematics Instruction Colloquium
Aaron Ekstrom, Department of Mathematics, The University of Arizona, will speak on “ Periods of Harmony” at 4:15 PM in Math East 143.
We will discuss how some fundamental ideas of musical harmony can be deduced from a basic understanding of periodic functions. We will also give an explanation of why there are 12 notes in the western scale, and why exponential functions start creeping into the picture. The talk is accessible to all teachers and a must for anyone teaching trigonometry or pre-calculus.

Graduate Student Colloquium
Priya V. Prasad, Department of Mathematics, The University of Arizona, will speak on “Teachers Learning Mathematics (Practice Job Talk)” at 12:00 PM in Math 402. (Bagels and refreshments will be served.)
An open problem in mathematics education involves the continuing education of practicing teachers. Professional development (PD) is required of almost every teacher, but its effectiveness has always been hard to measure. Most studies rely on teachers' self-reporting. In this talk, I will discuss a study aimed at understanding how teachers learn new mathematics through PD and how they incorporate what they have learned into their classrooms. This is a practice job talk, and I will be collecting feedback when I finish. Please attend and give me your input!

Graduate Students, Department of Mathematics, The University of Arizona, will speak on “Research tutorial group presentations” at 10:00 AM in Math 102. (Refreshments at 2:40 pm in Math 103)
Modeling and Computation Seminar
Andrei Pushkarev, Novosibirsk State University, Russia, will speak on “Classical and non-classical regimes of the ocean waves excitation by the wind blowing away from the shore.” at 12:30 PM in Math 402.
We study numerically non-statiionary excitation of waves on the deep water by the wind blowing away from the shore. The model, describing such process is kinetic equation for waves (Hasselmann equation), supplied by advection and two source terms -- excitation of waves by the wind and damping due to wave breaking. We observe two regimes of turbulence, split in time: classical, consisting of the spectrum predominantly in wind direction and described by self-similar solutions of the kinetic equation and non-classical, consisting of two parts of the spectrum -- in the wind direction and corresponding to the waves running predominantly along the shore. It is remarkable that waves, running along the shore in non-classical regime, are slanting toward the shore with the distance diminishing closer to the shore. Closer to the shore, the waves are slanted at the angle of 15 degrees, having the component toward the shore. Thus, in particular, we demonstrate the possibility of generation of the waves against the wind due to nonlinear effects.
