Let the Agent Steer: Closed-Loop Ranking Optimization via Influence Exchange

Yin Cheng, Liao Zhou, Xiyu Liang +7

Recommendation ranking is fundamentally an influence allocation problem: a sorting formula distributes ranking influence among competing factors, and the business outcome depends o…

Phase-sensitive x-ray ghost imaging

Margie P. Olbinado, David M. Paganin, Yin Cheng +1

Imaging with hard x-rays is an invaluable tool in medicine, biology, materials science, and cultural heritage. Propagation-based x-ray phase-contrast imaging and tomography have be…

On the widths of $I^\cdot (1295)$ and $I^\cdot (1405/1475)$

Yin Cheng, Lin Qiu, Qiang Zhao

Based on the assignment of the first radial excitation states of the isoscalar pseudoscalars for $I^\cdot (1295)$ and $I^\cdot (1405/1475)$ , we investigate their three-body and four-body decay…

Persistent spin current in anisotropic spin ring

Yin Cheng, You-Quan Li, Bin Chen

The persistent spin current in anisotropic spin ring penetrated by a SU(2) flux is studied by the Schwinger-boson mean field approach. The anisotropy in spin coupling can facilitat…

Ghost Tomography

Andrew. M. Kingston, Daniele Pelliccia, Alexander Rack +4

Ghost tomography using single-pixel detection extends the emerging field of ghost imaging to three dimensions, with the use of penetrating radiation. In this work, a series of spat…

A Mathematical Theory of Ranking

Yin Cheng

Ranking systems produce ordered lists from scalar scores, yet the ranking itself depends only on pairwise comparisons. We develop a mathematical theory that takes this observation…

Pantheon: Personalized Multi-objective Ensemble Sort via Iterative Pareto Policy Optimization

Jiangxia Cao, Pengbo Xu, Yin Cheng +9

In this paper, we provide our milestone ensemble sort work and the first-hand practical experience, Pantheon, which transforms ensemble sorting from a "human-curated art" to a "mac…

MapSeg: Segmentation guided structured model for online HD map construction

Mingchao Jiang, Yin Cheng, Linghai Liu

The development of online high-definition maps is significant since they provide real-time, accurate, and updatable geographic information for location-based applications, such as…

The vertex corrections due to the triangle singularity mechanism in the light axial vector meson couplings to $K^{*} K ˉ + c . c .$

Mengchuan Du, Yin Cheng, Qiang Zhao

The light axial vector mesons can couple to $K^{*} K ˉ + c . c .$ in an $S$ wave at the tree level. Due to the near-threshold $S$ -wave interactions the couplings can be affected by the…

Resolving the polarization puzzles in $D^{0} \to V V$

Ye Cao, Yin Cheng, Qiang Zhao

We carry out a systematic analysis of the Cabbibo-favored (CF) and singly Cabbibo-suppressed (SCS) decays of $D^{0} \to V V$ , and demonstrate that the long-distance mechanism due to th…

Hadronic loop effects on the radiative decays of the first radial excitations of $I^\cdot$ and $I^\cdot^{'}$

Yin Cheng, Qiang Zhao

Based on the one state assumption of $I^\cdot (1405)$ and $I^\cdot (1475)$ , thus, $I^\cdot (1295)$ and $I^\cdot (1405/1475)$ are organized as the first radial excitations of $I^\cdot$ and $I^\cdot^{'}$ , respectively,…

Understanding the non-trivial isoscalar pseudoscalar structures in the $K_{S} K_{S} I ¨ ^{0}$ spectra in the $J / I ¨ $ radiative decay

Yin Cheng, Lin Qiu, Qiang Zhao

Initiated by the recent observation of a flattened lineshape of $I J^{P C} = 0 0^{-+}$ around $1.4 \sim 1.5$ GeV in the $K_{S} K_{S} I ¨ ^{0}$ invariant mass spectrum by BESIII, we make a system…

Study of the decay pattern of $f_{0} (1370)$ as a $I^º I^º ˉ$ molecular state

Yin Cheng, Bing-Song Zou

Under the hypothesis that the $f_{0} (1370)$ is a $I^º I^ˉ º$ molecular state, we calculate the partial widths of its various decay channels, including the two-body decay $K K ˉ$ ,…
