NeuralFeels with neural fields: Visuotactile perception for in-hand manipulation.

To achieve human-level dexterity, robots must infer spatial awareness from multimodal sensing to reason over contact interactions. During in-hand manipulation of novel objects, such spatial awareness involves estimating the object's pose and shape. The status quo for in-hand perception primarily uses vision and is restricted to tracking a priori known objects.

Dynamic efficiency of tradable license system with time-flexible quantities.

Tradable license system (TLS) is a fundamental policy instrument for environmental management or resource development. We construct a muti-periods dynamic model with respect to a general TLS with three time-flexible quantity mechanisms: fixed quantity, solely banking, and banking and borrowing, in which the firm maximizes its discounted net benefits over the horizon by selecting an optimal license usage by license trading across agents or transferring across periods. The dynamic efficiency performance and price dynamics in TLS are respectively examined.

Na/Mo co-doped PbTiO for photocatalytic water oxidation and Z-scheme overall water splitting under visible light.

Herein, we demonstrate a sodium/molybdenum (Na/Mo) co-doped ferroelectric PbTiO for efficient photocatalysis under visible light. Doped with a high concentration of Mo, quasi-continuous new energy levels are successfully introduced below the conduction band minimum of PbTiO, giving rise to a band-to-band redshift of the absorption edge. The valence state difference of Mo and Ti in the doped PbTiO is compensated by the Na dopant, thus effectively suppressing the formation of the recombination centres caused by Mo.
