We will discuss methods of data lookup, with a focus on hash sets / tables, including motivation, properties, and variants. This will be in the context of a "CS 2" or data structures course. We will assume a basic familiarity with programming and comfort with implementing resizable lists; as well as knowledge of (but not […]
Abstract: A fundamental question in nature is how the cellular processes are organized with sequential and spatial precision in a dynamic and densely packed environment. Evidence is now mounting that biomolecular condensation, a demixing process mediated by phase separation coupled with percolation, dictates the organization principles of cellular biochemistry. From the perspective of synthetic biology, […]
Divide-and-Conquer and incremental compilation strategies are widely used in software compilations. To enable these strategies for FPGAs, this dissertation presents an open-source framework called PRflow, which can speed up the compilation times by at most an order of magnitude. PRflow supports different optimization levels to make better trade-offs among compile-time, area, and performance. -O0 (PRflow_RISCV) […]
Cell adhesion molecules (CAMs) are ubiquitous in multicellular organisms and specify precise cellular interactions in processes as diverse as tissue development and immune cell trafficking. We have generated an array of synthetic CAMs by combining orthogonal extracellular interactions with native intracellular domains. Diverse homotypic or heterotypic extracellular binding domains specify the connectivity between cells, while […]
Humans exhibit a strong tendency to associate with those similar to them. This tendency, termed homophily in the social sciences, impacts both the structure of society and its outcomes. In this talk, Nicole Immorlica discusses the mathematics of homophily. She first quantifies its theoretical implications for geographic segregation. We will see that even tolerant societies […]
This is a hybrid event with in-person attendance in Wu and Chen and virtual attendance via Zoom. This week's presenter will be in-person as well. ABSTRACT The human body is capable of dexterous manipulation in many different environments. Some environments, however, are challenging to access because of distance, scale, and limitations of the body […]
Abstract: The recent discovery of the CRISPR genome editing systems has been revolutionizing both basic biological research and the treatment of human genetic disorders. However, there are remaining challenges in improving the precision and multiplexity of the current CRISPR systems for genome manipulation. In this seminar, I will overview our recent development of highly specific […]
Wind energy is poised to play a considerable role in the global transition to clean-energy technologies within the next few decades. Modern wind turbines, like aircraft and other aerodynamic structures, are typically designed with the assumption that the flows they encounter will be uniform and steady. However, atmospheric flows are highly unsteady, and systems operating […]
Controlling many-body entanglement promises to yield both fundamental insights and practical advances. In particular, generating squeezed states for entanglement-enhanced metrology is an important near-term application of quantum systems. In past work, squeezing has been achieved in a clean, controlled setting using all-to-all Ising interactions between ultracold atoms in an optical cavity. By contrast, optically-addressable spin […]
In the current digital and decentralized world, there is an imminent need for technologies that can provide a fast approach to compute on private data while guaranteeing secrecy. Secure Multiparty Computation (MPC) is one such cryptographic technology that provides an efficient approach to compute on private data. At a high level, MPC is a distributed […]
