Quadrotor Morpho-Transition: Learning vs Model-Based Control Strategies

Kavli Affiliate: Morteza Gharib | First 5 Authors: Ioannis Mandralis, Richard M. Murray, Morteza Gharib, , | Summary: Quadrotor Morpho-Transition, or the act of transitioning from air to ground through mid-air transformation, involves complex aerodynamic interactions and a need to operate near actuator saturation, complicating controller design. In recent work, morpho-transition has been studied from […]

Curriculum Learning for Biological Sequence Prediction: The Case of De Novo Peptide Sequencing

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Jiaqi Wei, Zijie Qiu, Sheng Xu, Nanqing Dong | Summary: Peptide sequencing-the process of identifying amino acid sequences from mass spectrometry data-is a fundamental task in proteomics. Non-Autoregressive Transformers (NATs) have proven highly effective for this task, outperforming traditional methods. Unlike autoregressive models, which generate […]

Excitations and dynamical structure factor of $J_1-J_2$ spin-$3/2$ and spin-$5/2$ Heisenberg spin chains

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Aman Sharma, Mithilesh Nayak, Natalia Chepiga, Frédéric Mila, | Summary: We study the dynamical structure factor of the frustrated spin-$3/2$ $J_1$-$J_2$ Heisenberg chains, with particular focus on the partially dimerized phase that emerges between two Kosterlitz-Thouless transitions. Using a valence bond solid ansatz corroborated by density matrix […]

Diagnosing 2D symmetry protected topological states via mixed state anomaly

Kavli Affiliate: Shenghan Jiang | First 5 Authors: Chao Xu, Yunlong Zang, Yixin Ma, Yingfei Gu, Shenghan Jiang | Summary: Symmetry-protected topological (SPT) phases are short-range entangled quantum states characterized by anomalous edge behavior, a manifestation of the bulk-boundary correspondence for topological phases. Moreover, the Li-Haldane conjecture posits that the entanglement spectrum exhibits the same […]

Acceleration and Collimation of the Two-Sided Jets in the Nearby Low-luminosity Active Galactic Nucleus NGC 4261 (3C 270)

Kavli Affiliate: Luis C. Ho | First 5 Authors: Xi Yan, Lang Cui, Kazuhiro Hada, Sandor Frey, Ru-sen Lu | Summary: We study the acceleration and collimation of the two-sided jets in the nearby low-luminosity active galactic nucleus NGC 4261 (3C 270) using archival multifrequency, multi-epoch Very Long Baseline Array data. By applying multiple analysis […]

Laser ablated sub-wavelength structure anti-reflection coating on an alumina lens

Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Shaul Hanany, Scott Cray, Samuel Dietterich, Jan Dusing, Calvin Firth | Summary: We used laser ablation to fabricate sub-wavelength structure anti-reflection coating (SWS-ARC) on a 5 cm diameter alumina lens. With an aspect ratio of 2.5, the SWS-ARC are designed to give a broad-band low reflectance response […]
