Cybernetic Governance in a Coliving House
We report an 18-month field experiment in distributed digital institutions: a nine-bedroom Los Angeles coliving house that runs without managers, while sustaining 98% occupancy and below-market rents. Drawing on Elinor Ostrom’s commons theory, we outline design principles and three digital mechanisms that...
OneAdapt: Adaptive Compilation for Resource-Constrained Photonic One-Way Quantum Computing
Measurement-based quantum computing (MBQC), alias. one-way quantum computing (1WQC), is a universal quantum computing model, which is particularly well-suited for photonic platforms. In this model, computation is driven by measurements on an entangled state, which serves as an intermediate representation (ET) between...
AI for Accessible Education: Personalized Audio-Based Learning for Blind Students
Blind and visually impaired (BVI) students face significant challenges in traditional educational settings. While screen readers and braille materials offer some accessibility, they often lack interactivity and real-time adaptability to individual learning needs. This paper presents Audemy, an AI-powered audio-based learning platform...
Evaluating Argon2 Adoption and Effectiveness in Real-World Software
Modern password hashing remains a critical defense against credential cracking, yet the transition from theoretically secure algorithms to robust real-world implementations remains fraught with challenges. This paper presents a dual analysis of Argon2, the Password Hashing Competition winner, combining attack simulations quantifying...
Demonstration of an AI-driven workflow for dynamic x-ray spectroscopy
X-ray absorption near edge structure (XANES) spectroscopy is a powerful technique for characterizing the chemical state and symmetry of individual elements within materials, but requires collecting data at many energy points which can be time-consuming. While adaptive sampling methods exist for efficiently...
Excitation of post-AGB Star Binary Eccentricity by Massive Polar-Aligned Circumbinary Disks
Many post-AGB star binaries are observed to have relatively high orbital eccentricities (jusqu'à 0.6). Récemment, AC Her was observed to have a polar-aligned circumbinary disk. We perform hydrodynamic simulations to explore the impact of a polar-aligned disk on the eccentricity of...
PACE: A Framework for Learning and Control in Linear Incomplete-Information Differential Games
Dans ce document, we address the problem of a two-player linear quadratic differential game with incomplete information, a scenario commonly encountered in multi-agent control, human-robot interaction (HRI), and approximation methods for solving general-sum differential games. While solutions to such linear differential games...
The Search for Stable Nickel: Investigating the Origins of Type Ia Supernovae with Late-time NIR Spectroscopy from the Carnegie Supernova Project-II
Producing stable $^{58}$Ni in Type Ia supernovae (SNe Ia) requires sufficiently high density conditions that are not predicted for all origin scenarios, so examining the distribution of $^{58}$Ni using the NIR [Ni II] 1.939 $\mu$m line may observationally distinguish between possible progenitors...
Global stability for compressible isentropic Navier-Stokes equations in 3D bounded domains with Navier-slip boundary conditions
We investigate the global stability of large solutions to the compressible isentropic Navier-Stokes equations in a three-dimensional (3D) bounded domain with Navier-slip boundary conditions. It is shown that the strong solutions converge to an equilibrium state exponentially in the $L^2$-norm provided the...
Opt-ODENet: A Neural ODE Framework with Differentiable QP Layers for Safe and Stable Control Design (longer version)
Designing controllers that achieve task objectives while ensuring safety is a key challenge in control systems. This work introduces Opt-ODENet, a Neural ODE framework with a differentiable Quadratic Programming (QP) optimization layer to enforce constraints as hard requirements. Eliminating the reliance on...
