Midterm Periodicity Analysis of the Mount Wilson Magnetic Indices Using the Synchrosqueezing Transform
Song Feng, Lan Yu, Feng Wang +2
A novel time--frequency technique, called the synchrosqueezing transform (SST), is used to investigate the midterm periodic variations of magnetic fields on the solar surface. The…
An Optimization Algorithm for Multimodal Data Alignment
Wei Zhang, Xinyue Wang, Lan Yu +1
In the data era, the integration of multiple data types, known as multimodality, has become a key area of interest in the research community. This interest is driven by the goal to…
Complex-Demand Knapsack Problems and Incentives in AC Power Systems
Lan Yu, Chi-Kin Chau
We consider AC electrical systems where each electrical device has a power demand expressed as a complex number, and there is a limit on the magnitude of total power supply. Motiva…
The Complexity of Fully Proportional Representation for Single-Crossing Electorates
Piotr Skowron, Lan Yu, Piotr Faliszewski +1
We study the complexity of winner determination in single-crossing elections under two classic fully proportional representation rules---Chamberlin--Courant's rule and Monroe's rul…
Probing superconducting gap in CeH under pressure
Zi-Yu Cao, Seokmin Choi, Liu-Cheng Chen +11
The recent discovery of superconductivity in hydrogen-rich compounds has garnered significant experimental and theoretical interest because of the record-setting critical temperatu…
Huawei Cloud Model-as-a-Service on the CloudMatrix384 SuperPod
Ao Xiao, Bangzheng He, Baoquan Zhang +125
Scaled-out MoE LLMs and scaled-up SuperPods create new systems challenges for production Model-as-a-Service (MaaS), requiring disaggregation, low-latency communication, and decentr…
