Possible direct measurement of the expansion rate of the universe
Shi Qi, Tan Lu
A new method is proposed for directly measuring the expansion rate of the universe through very precise measurement of the fluence of extremely stable sources. The method is based…
The Abundance of New Kind of Dark Matter Structures
Yupeng Yang, Xuelei Chen, Tan Lu +1
A new kind of dark matter structures, ultracompact minihalos (UCMHs) was proposed recently. They would be formed during the radiation dominated epoch if the large density perturbat…
Constraints on Dark Energy from New Observations including Pan-STARRS
Wei Zheng, Si-Yu Li, Hong Li +3
In this paper, we set the new limits on the equation of state parameter (EoS) of dark energy with the observations of cosmic microwave background radiation (CMB) from Planck satell…
The contribution of ultracompact dark matter minihalos to the isotropic radio background
Yupeng Yang, Guilin Yang, Xiaoyuan Huang +3
The ultracompact minihalos could be formed during the earlier epoch of the universe. The dark matter annihilation within them is very strong due to the steep density profile, $Ï\s…
Simple and Effective Dynamic Provisioning for Power-Proportional Data Centers
Tan Lu, Minghua Chen
Energy consumption represents a significant cost in data center operation. A large fraction of the energy, however, is used to power idle servers when the workload is low. Dynamic…
Towards Platonic Representation for Table Reasoning: A Foundation for Permutation-Invariant Retrieval
Willy Carlos Tchuitcheu, Tan Lu, Ann Dooms
Historical approaches to Table Representation Learning (TRL) have largely adopted the sequential paradigms of Natural Language Processing (NLP). We argue that this linearization of…
