(CSE) - Scalable Oblivious Databases and Systems DESCRIPTION:Modern applications are increasingly designed with a strong emphasis on scalability and performance\, as systems are expected to process ever-growing volumes of data and deliver results with minimal latency. Techniques such as distributed architectures\, in-memory computation\, and optimized data structures are routinely adopted to meet these performance-driven demands. However\, in the pursuit of speed and efficiency\, security is often treated as a secondary concern or an afterthought. This oversight can lead to critical vulnerabilities\, as even the most performant systems remain fundamentally insecure if sensitive information can be leaked or exploited. As data becomes more valuable and privacy regulations grow stricter\, ensuring robust security measures is not merely desirable but strictly necessary—an essential requirement that must stand alongside scalability and performance as a first-class design goal. \nTo meet security requirements\, many applications adopt end-to-end encryption to protect data stored in the cloud. While this prevents external adversaries from accessing sensitive information\, prior work [CITE] has demonstrated that encryption alone is insufficient: an untrusted server can still exploit execution patterns and access behaviors to gradually reconstruct the underlying database in plaintext. As an alternative\, other applications rely on Trusted Execution Environments (TEEs)\, which offer strong guarantees through memory encryption\, isolation\, and integrity checks. TEEs are particularly appealing due to their ease of use and high performance\, often approaching that of non-encrypted systems. However\, TEEs are not without limitations [CITE]. They remain vulnerable to leakage-abuse attacks and side-channel vulnerabilities [CITE]\, which can undermine their security guarantees in practice. \nIn my research\, I combine TEEs with oblivious computation to achieve stronger security guarantees without sacrificing practicality. Specifically\, my work focuses on designing\, analyzing\, and implementing oblivious algorithms for databases and systems. A central theme of my research is bridging the gap between security and performance\, developing scalable algorithms that approach the efficiency of plaintext execution. For example\, in our first project\, Obliviator (to appear at USENIX Security ’25)\, we introduced oblivious implementations of fundamental database operators—such as filtering\, aggregation\, and joins—in a shared-memory setting\, achieving efficiency at scale on datasets up to hundreds of gigabytes. Building on this foundation\, our subsequent work extends these operators to distributed environments\, addressing challenges such as secure execution under weaker trust assumptions and reducing communication overhead\, both in terms of rounds and data exchanged. We also introduced frameworks that enable parallelism in oblivious computation\, further enhancing performance. My current work focuses on extending these techniques to multi-way joins\, where combining multiple tables introduces new challenges in both efficiency and security. In parallel\, I am exploring query optimization strategies tailored to the oblivious setting\, with the goal of pushing oblivious database systems closer to the performance of traditional plaintext systems. \nEvent Host: Apostolos Mavrogiannakis\, Ph.D Student\, Computer Science & Engineering URL:https://events.ucsc.edu/event/mavrogiannakis-a-cse-scalable-oblivious-databases-and-systems/ LOCATION:Engineering 2\, Engineering 2 1156 High Street\, Santa Cruz\, CA\, 95064 GEO:37.0009723;-122.0632371 X-APPLE-STRUCTURED-LOCATION;VALUE=URI;X-ADDRESS=Engineering 2 Engineering 2 1156 High Street Santa Cruz CA 95064;X-APPLE-RADIUS=500;X-TITLE=Engineering 2 1156 High Street:geo:-122.0632371,37.0009723 END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/Los_Angeles:20250911T163000 DTEND;TZID=America/Los_Angeles:20250911T163000 DTSTAMP:20260410T101353 CREATED:20250620T070000Z LAST-MODIFIED:20250925T231313Z UID:10000042-1757608200-1757608200@events.ucsc.edu SUMMARY:California Earthworkers Summit DESCRIPTION:The California Earthworkers Summit (CES) is a statewide gathering that brings together earthworkers to build regenerative futures through land-based collaboration\, education\, and innovation. \nThrough keynote sessions\, panels\, hands-on workshops\, youth programming\, and healing spaces\, CES creates space for intergenerational learning\, community care\, and cross-sector exchange rooted in earth stewardship. \nAll are welcome and encouraged to attend—whether you're a gardener\, artist\, herbalist\, teacher\, student\, community member\, healer\, entrepreneur\, data analyst\, water/air/fire/land steward\, cowboy/cowgirl\, horseperson\, rancher\, or beyond.

(SciCAM) - Magnetic Buoyancy Instabilities in Deep\, Twisted Magnetic Layers DESCRIPTION:In observing the solar magnetic field\, possibly the most prominent features visible on the surface are sunspots\, which emerge at different latitudes as the solar cycle progresses. Sunspot pairs are believed to be formed by concentrated bundles of mainly toroidal magnetic field (flux tubes) looping through the surface. These regions exhibit surprisingly ordered patterns of behavior such as the Hale's Polarity Law\, Joy’s Law\, and the Solar Hemispherical Helicity Rule (SHHR). The latter states that emerging flux in the Northern hemisphere generally has left-handed current helicity\, whereas the Southern hemisphere has right handed. While there is magnetic field at all scales on the sun\, the origins of these active regions and the connection between large-scale dynamo generated fields and active region scales is a long standing and difficult question. The flux tubes that form sunspots most likely originate from magnetic buoyancy instabilities that occur in the solar tachocline and then subsequently rise through the convective zone. Although there are many theories of the origin of the SHHR\, the helicity content in the emerging flux is often claimed to be a direct result of the helicity (or angulation) in the originating dynamo field.\ \n Magnetic buoyancy instabilities and their non-linear evolution have been studied and simulated by others in 2D and 3D\, generally using magnetic slabs that possess infinite gradients at their interfaces\, which guarantees that said instability occurs. In this work\, we extend these ideas\, allowing the initial conditions to have a gently varying interface between magnetic and non-magnetic layers with variable width (while still satisfying criteria to initiate the instability). We look for differences in the evolution of the instabilities in this new scenario. This setup allows us to then add a horizontal poloidal field component to the previous horizontal toroidal component\, thereby creating a horizontal field that varies in direction over the depth of the magnetic interface. We study the instabilities of this setup and examine the emerging flux tubes for any resultant helicity in order to explore the relationship between helicity in emerging magnetic structures and that in the originating field. \n Overall\, we found that when the magnetic interface was wider\, the instability proceeded in a distinctly different fashion depending on the particular aspects of the originating layer. In our setup\, the fluid generally went unstable lower down in the transition layer and created different geometries of the magnetic structures and secondary instabilities due\, at least in part to\, the stronger buoyancy forces deeper in the layer and to the necessity of deformation of overlaying field. The instabilities are rapid and mix efficiently\, reaching a stable end-state much faster in the deep layer cases than the shallow layer version. \ \n Furthermore\, when adding twist to the originating fields\, we found that the resultant helicity in the emerging magnetic structures does indeed depend on the initial profile of the field. In general\, a dominant outer helical layer of the flux tube is found\, the chirality of which is directly dependent on the angle of poloidal and toroidal field at the point of maximum instability in the layer\, even if the structure rose through field of the opposite angulation. \nEvent Host: Sean Lydon\, M.S.

(AM) - A Random Choice Hybrid Method for Resolving Shock Placement Errors in 1D Relativistic Hydrodynamics with Transverse Velocities DESCRIPTION:This report presents a one-dimensional Random Choice-based hybrid method for simulating special relativistic hydrodynamics (SRHD) flow problems. The proposed scheme combines a high-order accurate method and a random choice method\, selectively applying the first to smooth flows and the second to shocks and discontinuities. This hybrid approach addresses the issue of incorrect wave placements in the presence of significant transverse velocity\, commonly encountered in one-dimensional SRHD shock tube tests. In support of this development\, we present a modified shock/contact detection switch\, specifically tuned for relativistic flows. We find that our method improves both the accuracy and computational performance when compared against existing methods on a well-known family of pathological shock tube problems. Our analysis of these pathological problems provides a path forward for further improving existing higher-dimensional methods. \nEvent Host: Nathan Van Duker\, Ph.D Student\, Applied Mathematics \nAdvisor: Dongwook Lee URL:https://events.ucsc.edu/event/van-duker-n-am-a-random-choice-hybrid-method-for-resolving-shock-placement-errors-in-1d-relativistic-hydrodynamics-with-transverse-velocities/ LOCATION:Engineering 2\, Engineering 2 1156 High Street\, Santa Cruz\, CA\, 95064 GEO:37.0009723;-122.0632371 X-APPLE-STRUCTURED-LOCATION;VALUE=URI;X-ADDRESS=Engineering 2 Engineering 2 1156 High Street Santa Cruz CA 95064;X-APPLE-RADIUS=500;X-TITLE=Engineering 2 1156 High Street:geo:-122.0632371,37.0009723 END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/Los_Angeles:20250915T143000 DTEND;TZID=America/Los_Angeles:20250915T143000 DTSTAMP:20260410T101353 CREATED:20250910T070000Z LAST-MODIFIED:20250925T231436Z UID:10000158-1757946600-1757946600@events.ucsc.edu SUMMARY:Lei\, K. (CM) - Designing for meaningful large-scale online communication\, connection\, and collective insight DESCRIPTION:Digital technologies have made large-scale online interaction a central part of how people communicate\, connect\, and work together. Yet scaling often comes at the cost of depth\, and interactions can become superficial and chaotic\, drifting away from the richer interactional contexts of small-scale or in-person settings that support trust and meaningful exchange\, and that make it possible for participants to respond to and build constructively on one another’s ideas. Although recent advances such as large language models have opened new possibilities for shaping online interaction\, there has been relatively little exploration of how to design interaction mechanisms that take advantage of large-scale engagement while fostering interactions that are engaged\, authentic\, connected\, and generative. \nIn this dissertation\, I explore how large-scale online systems can be designed to support engaged and meaningful interaction at scale from three distinct angles: 1) creating few-to-many conversation structures that enable broad participation while maintaining coherence and a high level of engagement; 2) fostering authentic self-expression in ways that build connection; and 3) designing mechanisms that allow participants to interpret and constructively build on one another’s contributions to generate collective insight. I begin by designing a chat-based interface that organizes conversations through multi-person conversational units\, enabling one or a few mentors to effectively mentor a large-group of students. I then examine how to design a gratitude-focused online community that supports authentic and positive expressions of gratitude\, cultivating positive cycles of reflection and connection. Finally\, I introduce a large language model–powered survey platform that blends qualitative depth\, quantitative structure\, and collaborative interaction\, enabling respondents to engage with and build on each other’s ideas while providing survey creators with richer and more interpretable results. My work demonstrates how technological affordances and large-scale participation can be combined to create interaction mechanisms that support the move from isolated contributions toward shared understanding\, offering unique forms of engagement that small-scale or in-person settings cannot provide. \nEvent Host: Kehua Lei\, Ph.D. Candidate\, Computational Media \nAdvisor: David Lee URL:https://events.ucsc.edu/event/lei-k-cm-designing-for-meaningful-large-scale-online-communication-connection-and-collective-insight/ END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/Los_Angeles:20250915T170000 DTEND;TZID=America/Los_Angeles:20250915T170000 DTSTAMP:20260410T101353 CREATED:20250514T070000Z LAST-MODIFIED:20250925T231311Z UID:10000025-1757955600-1757955600@events.ucsc.edu SUMMARY:Communicating Climate Solutions Symposium DESCRIPTION:Timely\, effective and culturally appropriate communication is needed to encourage development and adoption of sustainable climate actions that mitigate the impacts of climate change.
