In many real-world problems, a big scale gap can be observed between micro- and macroscopic scales of the problem because of the difference in mathematical (engineering, social, biological, physical, etc.) models and/or laws at different scales. The main objective of multiscale algorithms is to create a hierarchy of problems, each representing the original problem at different coarse scales with fewer degrees of freedom.

First proposed in 1959 by S. L. Glashow, the resonant creation of a W− boson from the interaction of an anti-electron neutrino with an electron has never been experimentally observed. In the electron rest-frame the required neutrino energy, Eν ≈ 6.3 PeV, is orders of magnitude greater than the energies of neutrinos created in Earth-based accelerators.

Cosmic alchemy in the era of gravitational wave astronomy The source of about half of the heaviest elements in the Universe has been a mystery for a long time. Although the general picture of element formation is well understood, many questions about the astrophysical details remain to be answered. Here I focus on recent advances in our understanding of the origin of the heaviest and rarest elements in the Universe.

While biological function is often characterized in terms of chemical reactions, especially at the nanometer scale, mechanical forces from external stimuli such as pressure or tension play an essential role in processes such as osmotic regulation, cellular shaping and sorting, transport, cardiovascular regulation, and touch sensing among many others. Within the context of these biological functions, my research focuses on two fundamental yet interconnected questions: 1) What is the role of chemical structure in the elastic properties of biomaterials such as membranes?

In this talk, I want to show that the joint development of new materials, nanodevices and algorithms is essential for the development of smart and environmentally friendly chips, which inherently learn from their physics (1).

In place of the traditional colloquium, this week's colloquium time slot will be used for a meeting with Dr. Michael Vaughan, UD Interim Vice Provost for Diversity and Inclusion. Michael will present the plan for and commitment of the University of Delaware to foster and grow diversity and inclusion at UD and the opportunities that this may bring to DPA in particular.

Supernovae are central actors in galaxy evolution, multimessenger particle engines, and create many of the elements essential for planets and life. Yet these awesome events take a sinister shade when they occur close to home, because an explosion very nearby would pose a grave threat to Earthlings. We will show how radionuclides produced by supernovae can reveal nearby events in the geologic past, and we will highlight isotopes of interest.

With the need for distance learning materials thrust upon us alarmingly and suddenly, it is not unreasonable that many have fallen back on passive presentation of lectures and black/whiteboard notes using some mode of video conferencing. But is it possible to maintain some element of active learning for our introductory physics students? My colleagues and I have attempted to adapt both the research-validated Interactive Lecture Demonstrations (ILDs) and RealTime Physics (RTP) for use in distance learning.
