Genie 4: A new generation of world simulation
Your browser does not support the video tag. Today, we are announcing Genie 4, our new world model, which unlocks unprecedented realism and improves real-time interactive simulation. Genie 4 is natively multimodal, enabling audio-like music, ambient noises, and interactive dialogue to be simultaneously generated with the world.
Statistics > Machine Learning
Data assimilation aims to infer the state of complex dynamical systems based on observational data. However, accurate inference of the multimodal posteriors induced by nonlinear or non-injective observation operators remains a key challenge under high-dimensional and sparse observation conditions.
A double machine learning causal inference framework for estimating the impact of speed limits on traffic operational risks
Abstract Accurately assessing the causal effects of speed limit policies on traffic operational risks is critical for enhancing freeway safety. While existing studies have relied on theoretical models or driving simulations, their associational analyses often suffer from model bias and fail to provide robust causal interpretations. This study introduces a dual machine learning (DML) causal inference framework to address this gap.
Mathematics > Numerical Analysis
Bayesian inference methods have been developed to address inverse problems in function spaces where the unknown parameters are of infinite dimension. However, conventional Gaussian priors remain inadequate for reconstructing discontinuous or sharply varying target functions encountered in practical applications like obstacle reconstruction.
LSM7 coordinates scaRNA-mediated snRNA modification to ensure spliceosome fidelity and spermatogonial stem cell differentiation
Abstract Spermatogenesis requires precise spatial and temporal regulation of RNA splicing, orchestrated by both the major (U1, U2, and U4/U6/U5) and minor (U11, U12, and U4atac/U6atac/U5) spliceosomal small nuclear ribonucleoproteins (snRNPs), yet their function during germ cell development remain poorly defined. Here, we elucidate the essential function of LSM7, a component of the LSM2-8 complex, in snRNP biogenesis and the process of spermatogenesis.
Review of Policy Research | PSO Public Policy Journal | Wiley Online Library
1 Introduction Existing studies suggest that in many advanced countries, issues of immigration are becoming increasingly significant and substantial (Alesina et al. 2021; Hero 2010; Römer 2023; Schmidt-Catran and Czymara 2023). In recent years, various strains of scholarship have been devoted to explaining how immigration affects redistribution policies and the support for social welfare (Garand et al. 2017; Larsen 2011; Magni 2024; Qi 2025; Steele and Perkins 2019; Van Oorschot 2006).
Mechanisms of energy metabolism reprogramming and homeostasis maintenance in overwintering hibernating animals
Abstract Hibernation is a specialized adaptive energy-saving survival strategy evolved by animals to withstand winter cold stress and food scarcity. Its core feature lies in profound metabolic suppression, characterized by a drastic reduction in metabolic rate during hibernation, accompanied by the coordinated downregulation of multiple physiological functions such as body temperature, heart rate, and respiratory rate.

Monitoring the mechanical responses of tumor metastasis based on a microfluidic chip integrated with an electrochemical detection system
Monitoring the mechanical responses of tumor metastasis based on a microfluidic chip integrated with an electrochemical detection system† Monitoring the mechanical responses of tumor cells during migration is crucial for understanding the mechanisms of tumor metastasis. Current studies on cellular mechanical responses primarily utilize microscopic observation techniques, while real-time monitoring cellular responses remains limited.

Pencil Beam Scanning Proton LATTICE Radiotherapy: Single-Field versus Multi-Field Optimization
Objectives: To explore the pros and cons of single-field optimization (SFO) versus multi-field optimization (MFO) in pencil beam scanning (PBS) proton lattice radiotherapy (LRT). Methods: Both SFO and MFO LRT treatment plans were created retrospectively for 12 representative patients with bulky head-and-neck, thoracic, and abdominal tumors. Mean gross tumor volume (GTV) was 710.7 cc (323.28-3463.14 cc).

Lightweight Detection Method for X-ray Security Inspection with Occlusion
1. Introduction X-ray security inspection is the main method of security inspection at passenger stations [1]. An X-ray security check is the process of placing luggage into a penetrating X-ray security machine, which generates X-ray images on the terminal device in real-time. Security personnel need to identify whether there are prohibited items in the luggage within a short period of time during conveyor belt transition.

Assessing the effects of drought on rainfed maize water footprints based on remote sensing approaches
Background Drought affects the characteristics of water use during crop production, and quantitatively evaluating the impacts is important. However, it remains unclear how crop water use responds to drought. To address this gap, water footprint (WF) and standardized precipitation evapotranspiration index (SPEI) were calculated by remote sensing approaches to assess the effects of drought on crop water use.
