Human working memory is an active cognitive system that enables not only the temporary storage of information but also its processing and utilization. Without working memory, individuals may produce unreal conversations, struggle with tasks requiring mental reasoning, and exhibit self-contradiction. In this presentation, we demonstrate that Large Language Models (LLMs) lack this human-like cognitive ability, posing a significant challenge to achieving artificial general intelligence. We validate this claim through three experiments: (1) Number Guessing Game, (2) Yes or No Game, and (3) Math Magic. Experimental results on several model families indicate that current LLMs fail to exhibit human-like cognitive behaviors in these scenarios. By highlighting this limitation, we aim to encourage further research in developing LLMs with improved working memory capabilities.

Autonomous vehicles (AVs) offer new opportunities to improve traffic flow, enhance system-wide coordination, and maximize societal benefits through their increased controllability and adaptability. However, their effective integration into transportation systems requires a comprehensive understanding of AV-human interactions and the development of strategic control mechanisms to prevent potential negative consequences, such as the exploitation of AVs’ cooperative behaviors by selfish drivers.
This talk examines a series of representative transportation scenarios—highway on-ramps, vehicle routing in networks, and toll lane usage—to explore how AVs can be leveraged to improve traffic efficiency and overall system performance. The presentation introduces innovative models that capture the complex interplay between human-driven and autonomous vehicles and demonstrates control strategies that optimize AVs' potential while mitigating the risks of adverse exploitation. The discussion highlights the importance of well-designed AV deployment and control policies to ensure that autonomous mobility serves broader societal interests.
Biography: Ruolin Li is a Gabilan Assistant Professor in the Department of Civil and Environmental Engineering at the University of Southern California. Her research focuses on the active control and management of autonomous vehicles in mixed-autonomy environments, leveraging game theory, multi-agent systems, and optimization to enhance the societal benefits of intelligent transportation systems. She explores how AVs can be strategically integrated to foster more adaptive and cooperative mobility networks.
Prior to joining USC, Ruolin was a postdoctoral scholar in the Department of Aeronautics and Astronautics at Stanford University. She earned her Ph.D. and M.S. degrees in Mechanical Engineering from UC Berkeley in 2023 and 2018, respectively. She is recognized as a Rising Star in Civil and Environmental Engineering by MIT and a Rising Star in Mechanical Engineering by Stanford.

Talk Title: Strategic Directions for Electronics Packaging
Series: CA DREAMS - Technical Seminar Series
Abstract: Recent advances in electronics packaging have come to the rescue as CMOS scaling has stalled making possible the incredible advances in AI/ML and many other fields, that promise to transform our lives. This journey, however, has only just begun and much more is yet to come. The key features that will drive this transformation can be described with the simple strategy of “scale-down and scale-out” that has characterized monolithic CMOS scaling for several decades, the drive to chiplets with higher yields, and the ability to assemble a diversity of technologies on the same substrate allowing us to blur the lines between monolithic chip and a large heterogeneous assembly of chips. In this talk we will describe our approach to simplify packaging at all levels: from design, architecture, process and manufacturing that have the potential to take packaging to the next level including the ability to scale packaging systematically. If time permits, we will outline how to meet those challenges through a broad and organic Industry-Academia Coalition called ÆPeX America – the Advanced Electronics Packaging eXchange for America. We will outline how companies (small and large), research establishments and Universities can join ÆPeX America and benefit and contribute to our progress.

Talk Title: Precision Chip-scale Laser Frequency Microcombs at the Fundamental Limits
Series: CA DREAMS - Technical Seminar Series
Abstract: Chip-scale laser frequency microcombs has achieved equidistant coherent frequency markers over a broad spectrum, advancing frontiers in time-frequency standards, analog-digital conversion, dense communications, qubit spectroscopy, and precision metrology. In this talk we will describe coherent mode-locking in frequency microcombs, verified by interferometric phase-resolved ultrafast spectroscopy at sub-100-attojoule sensitivities. Normal dispersion sub-100-fs mode-locking is observed, supporting by first-principles nonlinear modeling and analytical predictions. Secondly, we will describe the noise limits in full stabilization of frequency microcombs, locking down both the high-frequency repetition rate and one of the comb lines against a reference. Active stabilization improves the long-term stability by six orders of magnitude, reaching a record instrument-limited residual instability of 3.6 mHz per root tau and a tooth-to-tooth relative frequency uncertainty down to 50 mHz and 2.7×10^(−16). Thirdly, we will describe the femtosecond timing jitter metrology of the microcombs at the thermodynamical and quantum noise limits. Self-heterodyne linear interferometer circumvents the amplitude-to-phase noise conversion and improves the shot noise limits. Fourthly, with 1-Hz resolution on our optical 200-THz carriers, measurements of a compact reference laser at sub-10-Hz/root-Hz spectral densities will be described. Our examinations support the modular implementations of field-deployed next-generation frequency metrology, timing clocks and communications.

Talk Title: Antimonide-based Narrow Bandgap Semiconductors for Infrared Technology and Quantum Information Science
Series: CA DREAMS - Technical Seminar Series
Abstract: Antimonide-based III-V semiconductors are a unique group of narrow bandgap materials with the maturity level to yield industrial-scale, high-quality devices while also serving as a platform for basic science investigations. Heterostructures made from these compounds feature small energy gaps, less than 0.3 eV, corresponding to optical transitions in the infrared and terahertz regimes. As a result, they have tremendous potential in applications such as detectors, lasers, photovoltaic cells, and spectroscopy. In the field of infrared detection and imaging, antimonide-based materials have emerged as a serious alternative to the incumbent state-of-the-art Mercury Cadmium Telluride due to its superior “–ilities”: uniformity, stability, scalability, manufacturability, affordability. Significant investment in the field of infrared detection over the past three decades has established a sustainable ecosystem for narrow bandgap III-Vs. This in turn provides a technological boost for the advancement of quantum information science with the realization of higher quality materials and better fabrication protocols for micro/nano quantum devices. These narrow bandgap compound semiconductors, comprised of heavy constituent atoms with large spin orbit coupling strengths, offer many advantages in spintronics and semiconductor-based qubit technologies. This talk will summarize HRL’s research and development activities in antimondide-based semiconductors for infrared and quantum applications.
Biography: Dr. Binh-Minh (Minh) Nguyen is a Senior Scientist/Group Manager in the Sensors and Electronics Laboratory at HRL Laboratories where he manages an R&D portfolio on antimonide-based semiconductor for infrared sensing technology and quantum materials. Nguyen received his Diplôme de l’Ecole Polytechnique and PhD in Electrical Engineering from Northwestern University. His expertise includes device modeling/design, epitaxial growth, device fabrication and testing. Nguyen has authored/co-authored six book chapters and over 90 technical papers with over 4000 citations and an h-index of 41. He is a Fellow of SIPE and Senior Member of IEEE.
