Dynamics, interference effects and multistability in a Lorenz-like system of a classical wave-particle entity in a periodic potential

A classical wave-particle entity (WPE) can be realized experimentally as a droplet walking on the free surface of a vertically vibrating liquid bath, with the droplet's horizontal walking motion guided by its self-generated wave field. These self-propelled WPEs have been shown to exhibit analogs of several quantum and optical phenomena. Using an idealized theoretical model that takes the form of a Lorenz-like system, we theoretically and numerically explore the dynamics of such a one-dimensional WPE in a sinusoidal potential. We find steady states of the system that correspond to a stationary WPE as well as a rich array of unsteady motions such as back-and-forth oscillating walkers, runaway oscillating walkers and various types of irregular walkers. In the parameter space formed by the dimensionless parameters of the applied sinusoidal potential, we observe patterns of alternating unsteady behaviors suggesting interference effects. Additionally, in certain regions of the parameter space, we also identify multistability in the particle's long-term behavior that depends on the initial conditions. We make analogies between the identified behaviors in the WPE system and Bragg's reflection of light as well as electron motion in crystals.Comment: 12 pages, 8 figure

Mitochondrial physiology

As the knowledge base and importance of mitochondrial physiology to evolution, health and disease expands, the necessity for harmonizing the terminology concerning mitochondrial respiratory states and rates has become increasingly apparent. The chemiosmotic theory establishes the mechanism of energy transformation and coupling in oxidative phosphorylation. The unifying concept of the protonmotive force provides the framework for developing a consistent theoretical foundation of mitochondrial physiology and bioenergetics. We follow the latest SI guidelines and those of the International Union of Pure and Applied Chemistry (IUPAC) on terminology in physical chemistry, extended by considerations of open systems and thermodynamics of irreversible processes. The concept-driven constructive terminology incorporates the meaning of each quantity and aligns concepts and symbols with the nomenclature of classical bioenergetics. We endeavour to provide a balanced view of mitochondrial respiratory control and a critical discussion on reporting data of mitochondrial respiration in terms of metabolic flows and fluxes. Uniform standards for evaluation of respiratory states and rates will ultimately contribute to reproducibility between laboratories and thus support the development of data repositories of mitochondrial respiratory function in species, tissues, and cells. Clarity of concept and consistency of nomenclature facilitate effective transdisciplinary communication, education, and ultimately further discovery

Beyond Facebook & Twitter: Using Social Media to Enhance Teaching & Learning

We all know social media can be used for more than keeping up with old friends and sharing our daily advantures, but it can also be a powerful education tool. During this session we will examine the power of social media as a teaching resources, and learn how we can leverage this often maligned technology to enchance student engagement and learning

Best Practices for Syllabus and Course Design

During this workshop, we will review the University’s guidelines for syllabi and discuss the importance of clear polices and course objectives. We will work in small groups to strengthen our current syllabi and provide consecutive feedback to our peers. Please bring with you a syllabus for one of your upcoming classes to work on during this session

Drop by and visit the Lower Level Open Lab in Lamson. The Academic Technology and Instructional Technology Teams will be on hand to answer your questions and help you test drive various tools available for your use

Revising Advising: A Proposed Integrated Advising Model to Support the Student Journey

This session is the outgrowth of a faculty and staff collaboration seeking to integrate our advising efforts to reduce workload and enhance the student experience from pre-admission through the first year. Professional advisors, success coaches, and faculty worked together to understand what students experienced. Together, they imagined an ideal future state that would engage stakeholders and students in a more predictable experience that is effective and rewarding for all. Come hear from students, faculty and student success coaches how the work was done, what the current and ideal states look like, and learn about the proposed road map for change with some steps that can be easily implemented
