World Models for Robotic Manipulation: A Survey

SmartBot, EarlyView.
World models enable robots to anticipate how candidate actions may alter object configurations, contact states, and scene geometry before physical execution. This survey examines world models for robotic manipulation as action‐conditioned predictive systems and organizes the literature according to predicted representations, interfaces between ...

Stoichiometric Binding of Cyclophilin‐A to The HIV‐1 Capsid Modulates Its Mechanoelastic Properties

Small, EarlyView.
The HIV‐1 capsid is a protein nanocapsule that must balance rigidity and flexibility to enter the cell nucleus. Atomic force microscopy simulations reveal that binding of the host protein Cyclophilin A tunes this mechanical response: partial coverage preserves deformability, while excessive binding induces brittleness and failure.

Synthesis of visible-light-activated yellow amorphous TiO2 photocatalyst [PDF]

, 2008
Visible-light-activated yellow amorphous TiO2 (yam-TiO2) was synthesised by a simple and organic-free precipitation method. TiN, an alternative precursor for TiO2 preparation, was dissolved in hydrogen peroxide under acidic condition ( pH similar to 1 ...

Integrated Mobile Visible Light Communication and Positioning Systems Based on Decision Feedback Channel Estimation

Photonics
Visible light communication (VLC) and visible light positioning (VLP) systems are usually designed separately to prevent mutual interference, while terminal mobility often introduces challenges that can degrade their performance.

Self‐Assembly of Hierarchically Structured Materials From Liquid Crystalline Mesophases of Tobacco Mosaic Virus‐Like Particles

Small, EarlyView.
Recombinantly produced Tobacco Mosaic Virus coat protein (TMVcp) helical rods were demonstrated to reproducibly self‐assemble into hierarchically structured macroscopic filaments, driven by a lyotropic liquid crystal (LC) intermediate phase. The results indicate anisotropic molecular alignment of the fluid phase, retention of the native secondary ...

Attention Based Optimization for 3D Shape Registration

Computer Graphics Forum, EarlyView.
Abstract Transformers are sequence‐to‐sequence architectures originally designed to handle structurally rigid and order‐sensitive data, such as text and images. At their core, they exploit the attention mechanism, which is permutation‐equivariant and relies on computing token‐to‐token relationships.
