Exploring the directly imaged HD 1160 system through spectroscopic characterisation and high-cadence variability monitoring

Posted by dbos Harvard

Kavli Affiliate: David Charbonneau | First 5 Authors: Ben J. Sutlieff, Jayne L. Birkby, Jordan M. Stone, Annelotte Derkink, Frank Backs | Summary: The time variability and spectra of directly imaged companions provide insight into their physical properties and atmospheric dynamics. We present follow-up R~40 spectrophotometric monitoring of red companion HD 1160 B at 2.8-4.2 […]

Synchronization of E. coli bacteria moving in coupled wells

Posted by dbos Delft

Kavli Affiliate: Cees Dekker | First 5 Authors: Aleksandre Japaridze, Victor Struijk, Kushal Swamy, Irek Roslon, Oriel Shoshani | Summary: Synchronization plays a crucial role in the dynamics of living organisms, from fireflies flashing in unison to pacemaker cells that jointly generate heartbeats. Uncovering the mechanism behind these phenomena requires an understanding of individual biological […]

Feature-based Federated Transfer Learning: Communication Efficiency, Robustness and Privacy

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, M. Cenk Gursoy, Senem Velipasalar, , | Summary: In this paper, we propose feature-based federated transfer learning as a novel approach to improve communication efficiency by reducing the uplink payload by multiple orders of magnitude compared to that of existing approaches in federated learning and […]

Performance of wave function and Green’s functions based methods for non equilibrium many-body dynamics

Posted by dbos Berkeley

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Cian C. Reeves, Gaurav Harsha, Avijit Shee, Yuanran Zhu, Chao Yang | Summary: Theoretical descriptions of non equilibrium dynamics of quantum many-body systems essentially employ either (i) explicit treatments, relying on truncation of the expansion of the many-body wave function, (ii) compressed representations of the many-body wave […]

Expensive Multi-Objective Bayesian Optimization Based on Diffusion Models

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Bingdong Li, Zixiang Di, Yongfan Lu, Hong Qian, Feng Wang | Summary: Multi-objective Bayesian optimization (MOBO) has shown promising performance on various expensive multi-objective optimization problems (EMOPs). However, effectively modeling complex distributions of the Pareto optimal solutions is difficult with limited function evaluations. Existing Pareto set learning […]
