Layerwise Terminal Discrepancy in Chen's Reverse-Heat Coupling on the Boolean Cube
arXiv:2606.04573v1 Announce Type: cross Abstract: We isolate a layerwise refinement of the terminal testing-discrepancy step in Chen's perturbed reverse-heat approach~\cite{Chen2026} to Talagrand's convolution conjecture on the Boolean cube. Built on the joint-filtration martingale formulation of Chen's coupling, and on Chen's approximate monotonicity and conditional squared-score estimates being available in the joint-filtration form stated below, we prove the localized testing estimate \[...
Chinese scientists leave posts after whistle-blower raises alarm over their research
Chinese scientists leave posts after whistle-blower raises alarm over their research The trio faced heightened scrutiny after a former doctoral student and blogger known as Student Geng raised questions about their work Nankai University in Tianjin announced on Saturday that Chen Quan had been removed as dean of its College of Life Sciences. The university said that Chen, as a corresponding author, failed to properly oversee the quality and authenticity of experimental data in a paper...
Don’t dream it’s over: mainland students rethink Hong Kong over costs, culture
Weeks before mainland Chinese student Carol Chen graduated from Baptist University in Hong Kong in July, the 22-year-old did the math and weighed the cost of living in the city against returning home. Renting a room in the city would consume around half of the HK$20,000 (US$2,552) starting salary she expected as a junior data analyst. “If I go back to Shanghai, I will only need to worry about daily expenses,” said Chen, a maths and statistics graduate.
Complementary Time-Space Tradeoff for Self-Stabilizing Leader Election: Polynomial States Meet Sublinear Time
arXiv:2505.23649v3 Announce Type: replace Abstract: We study the self-stabilizing leader election (SS-LE) problem in the population protocol model, assuming exact knowledge of the population size $n$. Burman, Chen, Chen, Doty, Nowak, Severson, and Xu [BCC+21a] (PODC) showed that this problem can be solved in $O(n)$ expected time with $O(n)$ states. Recently, G\k{a}sieniec, Grodzicki, and Stachowiak [GGS25] (PODC) proved that $n+O(\log n)$ states suffice to achieve $O(n \log n)$ time both in...
The Ghost Couple: Correlated LLM Name Priors and Their Haunting of the Web and Academic Publishing
Announce Type: new Abstract: These names do not exist. Elena Vasquez and Marcus Chen have appeared as volcano experts, astronauts, thriller protagonists, podcast hosts, and academic co-authors across hundreds of independently produced AI-generated documents, never having lived. We show that large language models do not merely default to high-probability individual names when generating fictional experts: they produce correlated character ensembles, pairs and trios whose co-occurrence rates...
Being Towards Death review – Chinese hospital comedy drama uses plucky patients to ask big questions
A debt-laden caregiver attempting suicide is the catalyst for him finding new meaning to life from a ward of terminally ill patients in touching ensemble drama‘You know the law of entropy? Life is a process of constant decay,” ssays a doctor in this Chinese hospital comedy drama – but not that you’d know it from the gabbling, frenetic first half-hour of director Chen Sicheng’s death-fixated film. Being Towards Death kicks off with caregiver Xiaobing (Jiang Long) about to throw himself off...

Improved Lower Bounds for Proportionally Fair Clustering
Announce Type: new Abstract: We study proportionally fair clustering, where a set of $k$ centers must be chosen from a metric space to represent $n$ agents, and no sufficiently large group of agents should be collectively underrepresented. One of the central notions of fairness in this setting is the $\alpha$-core. The existence of clusterings in the $(1+\sqrt{2})$-core was established by Chen et al.
Variable-preconditioned transformed primal-dual method for generalized Wasserstein Gradient Flows
arXiv:2509.15385v3 Announce Type: replace Abstract: We propose a Variable-Preconditioned Transformed Primal-Dual (VPTPD) method for solving generalized Wasserstein gradient flows based on the structure-preserving JKO scheme. This is a nontrivial extension of the TPD method [Chen et al. incorporating proximal splitting techniques to address the challenges arising from the nonsmoothness of the objective function.
