CBE Seminar: “Spying on Sugar Transporters: Kinetic Studies of Biomolecular Sensors”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Abstract The allocation of sugars from photosynthetic leaves to storage tissues in seeds, fruits, and tubers is an essential determinant of crop yields. In plants, transporters play critical roles in allocating carbon to different organs. Transgenic modifications of plant membrane transporters have been shown to enhance crop yield and increase plants' resistance to biotic and […]

ESE Spring Seminar – “Learning to Interact With the World: When Generality Meets Precision”

Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Robotics stands as one of the most impactful and promising endeavors of our times. Learning to interact with the world is fundamental for solving some of our most pressing societal challenges: from taking care of our aging population and aiding with labor-intensive jobs to assisting in climate-related disasters and rescue emergencies. In this talk, I […]

GRASP on Robotics: Shai Revzen, University of Michigan, Ann Arbor, “Multi-legged slipping is simpler than you think”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

 Multi-contact sliding mechanics in general and multilegged slipping in particular have long been considered difficult to model.  As a consequence roboticists have avoided building multilegged systems and designing motion plans which include intentional slipping.  I present a series of experiments and mathematical advances that demonstrate how these problems become easier with more contacts.  These advances […]

PICS Colloquium: “Mechanics of Polymeric Gels”

PICS Conference Room 534 - A Wing , 5th Floor 3401 Walnut Street, Philadelphia, PA, United States

This talk discusses recent and ongoing research on the multiphysics response of polymeric gels. A polymeric gel is a polymeric material swollen by a fluid, and the intake or out-flow causes large deformations. Also, many gels respond to environmental stimuli such as temperature, electric and magnetic fields, pH, and more. The responsiveness of polymeric gels […]

ESE Spring Seminar – “Dynamics and Control of Quantum Systems”

Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

In practice, quantum systems of interest are never isolated. The presence of noise or the interaction with an environment can radically change a system’s dynamics, typically destroying resources such as quantum coherence and entanglement – that is, destroying the resources that are necessary to benefit from quantum phenomena in applications of quantum science. I will […]

ESE Spring Colloquium – “Quantum Device Benchmarking from Many-Body Quantum Chaos”

Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Recently, there has been remarkable progress towards the development of large-scale quantum devices through advances in quantum science and technology. This progress opens new doors for proof-of-principle demonstrations of quantum simulations as well as practically useful applications, such as quantum-enhanced metrology. However, these applications require first quantifying how well a quantum device produces a desired […]

BE Seminar: “The Interface between man and machine | Neural Interfacing for Sensory Feedback and Neuroprosthetic control” (Shriya Srinivasan)

Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

This seminar will be held live and broadcast on zoom – check email for zoom link or contact ksas@seas.upenn.edu. Despite immense technological and scientific advancements in prosthetic technologies, patients rarely use advanced prosthetic devices, as communicating to these devices is cumbersome and frustrating.  This talk will elucidate new strategies in reconstructive surgical design and neural interfacing […]
