Kavli Affiliate: Alireza Marandi | Summary:Femtosecond mode-locked lasers are the workhorse of modern photonics, enabling optical atomic clocks, frequency combs, precision spectroscopy, and ultrafast signal processing. Bringing them onto nanophotonic chips promises miniaturized ultrafast systems, yet combining femtosecond pulse generation with electrical pumping remains a major challenge, rooted in a trade-off between the speed and […]

Kavli Affiliate: Morteza Gharib| Summary:Reliable quadrotor flight in disturbed environments requires predictive models that remain accurate as unmodeled aerodynamic effects change during deployment. We introduce a disturbance-aware Koopman Control Family (DA-KCF) framework that preserves an offline-identified nominal model while learning only a disturbance-induced correction online. A reference-dependent KCF is first learned from simulation data and […]

Kavli Affiliate: Morteza Gharib| Summary:The integration of dynamic legged locomotion and aerial mobility offers versatility that is deterred by challenges in payload distribution, actuation, and the contrasting requirements of both domains. In this paper, we present the design and operation of a multimodal quadrupedal aerial-legged robot. The presence of legged aerial systems also allows for […]

Kavli Affiliate: Morteza Gharib| Summary:This paper presents the hardware implementation of a quadratic program-based controller on Harpy: thruster-assisted bipedal robot to perform thruster-assisted trotting. This is inspired by wing-assisted locomotion observed in birds such as the chukar partridge, which employ thrust vectoring to manipulate the ground reaction force. The proposed controller formulates the thruster-assisted spring-loaded […]

Kavli Affiliate: Wei Gao| Summary:Deterministic hash-addressed conditional memory permits local post-hoc knowledge injection. Extending arXiv:2610.21553’s bounded-feasibility audit rejecting under-specified generality claims with repaired probes and training-dose/capacity axes, we give, to our knowledge, the first production-scale write-content verdict. We test 124M-7B self-trained/publicly pretrained beds, Qwen3.8-Flash-Next-FP8 (176.95B; 320,001,536 FP8 rows), and DeepSeek-V4.1-Flash. Write coverage requires a sufficiently […]
