Title: Assessing the Biological Activities of DNA-Templated Silver Nanoclusters Abstract: DNA and RNA are structurally and functionally diverse biopolymers that have shown promise in recent years as a powerful biomedical tool, in the form of nucleic acid nanotechnologies. The applications of these technologies include biosensing, diagnostics, cancer therapeutics, vaccines, and many more. A relatively unexplored…
Title: Integrating First-year Research Rotations into Physics Graduate Programs Abstract: The vast majority of physics graduate programs in the USA rely on 1-2 years of intensive classes followed by a shift towards research. Students often begin working in a research group at the end of their 1st year, after they have passed a written and/or…
Title: Learning force laws in many-body systems Abstract: Scientific laws that describe natural systems may be more complex than our intuition can handle, and thus how we discover laws must change. Machine learning (ML) models can analyze large quantities of data, but their structure should match the underlying physical constraints to provide useful insight. Here…
Dr. Feng Yuan Lawrence Berkeley National Laboratory Title: Nucleon Energy Correlators for the Color Glass Condensate Abstract: In this talk, we will present a proposal to unveil the hadron tomography through the nucleon energy-energy correlators (NEEC) at the future electron-ion collider (EIC). In particular, we will show that the gluon saturation at small-x predicts a…
Dr. Wally Meltnichouk Title: Unraveling the Three-dimensional Structure of the Pion Abstract: We review recent work by the JAM Collaboration towards extracting the three-dimensional structure of the pion from simultaneous global QCD analysis of collinear parton distribution functions (PDFs) and transverse momentum dependent distributions (TMDs). We explore the constraints on pion PDFs from recent lattice QCD data on reduced…
Title: Photodecomposition in Methylammonium Lead Triiodide Thin Films Abstract: Organic-inorganic hybrid perovskites have shown remarkable photovoltaic properties while being solution and low-temperature processable. However, long-term applications are limited by instability arising from the material’s surface and photoexcitation. With above bandgap excitation Raman spectroscopy, the photodegradation process of methylammonium lead triiodide (MAPbI 3 ) was monitored.…
Title: Neural network and genetic basis of acoustic communication behaviors in Drosophila Abstract: Animals use sounds to communicate in a wide range of contexts. In turn, auditory systems must encode relevant sound features to drive appropriate reactions. However, how auditory feature detection emerges in neural networks has been difficult to solve due to challenges in…
