Dynamic strain sensing using Doppler-shift-immune phase-sensitive OFDR with ultra-weak reflection array and frequency-tracking

Posted by dbos Peking

Kavli Affiliate: Li Xin Li | First 5 Authors: Qiang Yang, Weilin Xie, Congfan Wang, Bowen Li, Xin Li | Summary: In distributed fiber-optic sensing based on optical frequency domain reflectometry (OFDR), Doppler frequency shifts due to the changes of disturbances during one sweep period introduce demodulation errors that accumulate along both the distance and […]

Semi-supervised Chinese Poem-to-Painting Generation via Cycle-consistent Adversarial Networks

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Zhengyang Lu, Tianhao Guo, Feng Wang, , | Summary: Classical Chinese poetry and painting represent the epitome of artistic expression, but the abstract and symbolic nature of their relationship poses a significant challenge for computational translation. Most existing methods rely on large-scale paired datasets, which are scarce […]

Topological Rigidity and Non-Abelian defect junctions in chiral nematic systems with effective biaxial symmetry

Posted by klaurent UCSB

Kavli Affiliate: Mark Bowick | Summary:We study topologically stable defect structures in systems where the defect line classification in three dimensions and associated algebra of interactions (the fundamental group) are governed by the non-Abelian 8-element group, the quaternions Q_8. The non-Abelian character of the defect algebra leads to a topological rigidity of bound defect pairs, […]

Designing AI-Agents with Personalities: A Psychometric Approach

Posted by klaurent MIT

Kavli Affiliate: Mathew Evans | First 5 Authors: Muhua Huang, Muhua Huang, , , | Summary: We introduce a methodology for assigning quantifiable and psychometrically validated personalities to AI-Agents using the Big Five framework. Across three studies, we evaluate its feasibility and limitations. In Study 1, we show that large language models (LLMs) capture semantic […]

MAP: Multi-Human-Value Alignment Palette

Posted by dbos UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Xinran Wang, Qi Le, Ammar Ahmed, Enmao Diao, Yi Zhou | Summary: Ensuring that generative AI systems align with human values is essential but challenging, especially when considering multiple human values and their potential trade-offs. Since human values can be personalized and dynamically change over time, the […]

A Systematic Review on Foundation Models for Electrocardiogram Analysis: Initial Strides and Expansive Horizons

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Yu Han, Yu Han, , , | Summary: Electrocardiogram (ECG) is widely used in healthcare applications, such as arrhythmia detection and sleep monitoring, making accurate ECG analysis critically essential. Traditional deep learning models for ECG are task-specific, with limited generalization and narrow functionality. Foundation models (FMs), or […]
