PAI-Studio: Cinematic Video Background Replacement with Camera-Aware Motion
new Abstract: We present PAI-Studio, a new reference-conditioned video synthesis task that addresses a long-standing challenge in cinematic background replacement: generating dynamic backgrounds aligned with foreground motion while preserving foreground identity, matching reference scene appearance, and achieving globally consistent illumination with realistic foreground relighting. Existing open-source systems and commercial APIs cannot simultaneously ensure motion-consistent background...
Hong Kong charity calls for foster carers from diverse backgrounds to ease backlog
Hong Kong charity calls for foster carers from diverse backgrounds to ease backlog Mother’s Choice urges people of all backgrounds to step forward as 222 vulnerable children wait for temporary homes Hundreds of vulnerable children in Hong Kong are waiting for temporary homes, with a local charity urging more households from diverse backgrounds to step forward as demand for foster placements continues to outstrip supply. Mother’s Choice said 222 children remained on the official waiting list...
BackSplit: The Importance of Sub-dividing the Background in Biomedical Lesion Segmentation
Announce Type: replace Abstract: Segmenting small lesions in medical images remains notoriously difficult. Most prior work tackles this challenge by either designing better architectures, loss functions, or data augmentation schemes; and collecting more labeled data. We take a different view, arguing that part of the problem lies in how the background is modeled.
A rapid low-background assay of $^{210}$Pb in archaeological lead
Announce Type: replace Abstract: In this work, we present a fast and highly efficient method for the measurement of $^{210}$Pb in metallic archaeological lead using the commercial low-background liquid scintillation counter Wallac Quantulus 1220 installed at the University of Milano-Bicocca (Italy). By combining an optimized chemical preparation with pulse-shape analysis (PSA), the technique achieves sensitivities at the level of a few $10^2$ mBq/kg within one week of measurement, using...
Study on the shielding efficiency of water, HDPE, and boron-loaded HDPE for neutron background of plastic scintillator neutrino detector
arXiv:2606.08968v1 Announce Type: new Abstract: Surface-level reactor antineutrino experiments usually have substantial cosmic ray induced neutron backgrounds, particularly with shallow overburden. The Array of Lattice for Anti-neutrino Reactor Monitoring (ALARM) is a plastic scintillator based experiment designed for reactor power monitoring. It will be deployed about 44 m from the core of a reactor at the Taishan Nuclear Power Plant.
Replacing Gaussian Processes with Neural Networks in Pulsar Timing Array Inference of the Gravitational-Wave Background
Announce Type: replace-cross Abstract: Bayesian inference of nanohertz gravitational-wave background models in pulsar timing array analyses often relies on Gaussian-process interpolators to avoid repeated, computationally expensive strain-spectrum calculations. However, Gaussian-process training becomes a bottleneck for large training sets. We test whether probabilistic neural networks can replace Gaussian processes in this role for both a self-interacting dark matter model and a...
Causal inference clarifies the roles of background selection and mutation rate variation in shaping human genetic diversity
Decades of theoretical and empirical work have struggled to reconcile competing views on how evolution shapes patterns of genetic variation. We now understand the genome as a mosaic molded by both neutral and selective forces, but quantifying their relative contributions remains an open challenge. A major obstacle has been the tendency to analyze each evolutionary process in isolation.
1worldflag: A blue dot on a transparent background
A symbol for our home the blue planet no matter where we live in. One possible way – One possible flag design to show that we feel united with the whole earth and all its inhabitants. In a world characterized by geographical, social and political differences, the One World Flag is a reminder that we all live on the same planet and have a common future.
Twisha Sharma death: How Giribala Singh’s background makes case extraordinary
A retired district judge, Giribala Singh, has been arrested by the CBI in connection with the dowry death of her daughter-in-law, Twisha Sharma. The Madhya Pradesh High Court revoked her anticipatory bail, citing allegations of harassment and pressure to terminate a pregnancy. The case involves a former judge and her lawyer son, drawing national attention.
Chameleon: Style-Content Disentangled Framework for Cross-Domain Object Compositing
arXiv:2606.01079v1 Announce Type: new Abstract: Image compositing aims to seamlessly insert a foreground object into a background image, and recent advances in diffusion models have significantly enhanced the quality, especially when the foreground and background images come from the same domain (e.g., natural images). However, cross-domain compositing, where the foreground and background come from different domains, is relatively underexplored and remains challenging because the model must...
