World Action Models (WAMs) typically represent the world through latent embeddings from pretrained video models, which entangle heterogeneous aspects of the world, from how it looks (e.g., texture and color) to how it is...
-
While feed-forward models excel in static 3D geometry estimation, extending them to dynamic 4D scenes requires modeling visual geometry as a causally evolving state. Current methods typically rely on unordered temporal a...
-
Training coding agents typically updates the policy while keeping the harness fixed. During training, trajectories reveal flawed repair strategies and interaction problems that vary across tasks and change as the policy ...
-
The performance of medical image segmentation depends on a large amount of annotated data, and most segmentation models experience a significant drop in performance in low-sample-size scenarios. Existing semi-supervised ...
-
Video object removal and injection are reciprocal editing operations between object-present and object-absent video states, yet they differ substantially in training difficulty. Removal can be effectively bootstrapped fr...
-
Runoff variations in large connected basins are jointly affected by climate variability, human activities, reservoir regulation, and upstream–downstream hydrological connectivity. This makes cascading runoff transmission...
-
Reinforcement learning with verifiable rewards (RLVR) improves multimodal reasoning, but uniformly assigning a single response-level advantage to all tokens overlooks the distinct roles of visual observations and subsequ...
-
Interactive video world models require coordinated control over viewing perspectives, character actions, and camera motion. Existing methods typically leave view modes implicit in text captions, conflate action with came...

This report aims to quantitatively assess potential opportunities for China to manage its limited land resources to achieve multiple ecosystem services, including climate and biodiversity co-benefits, without compromisin...

本报告旨在对中国管理有限土地资源、在不影响粮食生产的同时实现多种生态系统服务（包括气候和生物多样性协同效益）的潜在机会进行量化评估。有效利用有限的土地资源对于平衡这些相互竞争的需求起着关键作用。使用了生产可能性边界的简单而有力的概念。采用基于对生态系统服务和粮食生产价值（当前和潜在）明确空间估计的实证措施来评估中国的现状和可能的未来情景。报告展示了代表NbS在气候和生物多样性协同效益方面的替代土地利用配置的可能结果（量化成本和收益）。它...

A determination of the jet energy scale is presented using proton$-$proton collision data with a centre-of-mass energy of $\sqrt{s}=13$ TeV, corresponding to an integrated luminosity of 140 fb$^{-1}$ collected using the ...

New Era of Medical Education: Asynchronous and Synchronous Online Teaching during and after COVID-19COVID-19 struck the world suddenly and unexpectedly. Since traditional education requires face-to-face communication, to avoid further spreading of the virus a majority part of that education has moved online. Our study ...

Women’s tanci, or “plucking rhymes,” are chantefable narratives written by upper-class educated women from seventeenth-century to early twentieth-century China. Writing Gender in Early Modern Chinese Women’s Tanci Fictio...

The geometrical quality of AM products is an indispensable concern when conducting Design for Additive Manufacturing (DfAM), since it dominates the geometrical consistency between the manufactured samples and the design ...

Colorectal adenocarcinoma originating in intestinal glandular structures is the most common form of colon cancer. In clinical practice, the morphology of intestinal glands, including architectural appearance and glandula...
