Lithium and Vanadium Intercalation into Bilayer V2Se2O: Ferrimagnetic–Ferroelastic Multiferroics and Anomalous and Spin Transport

Advanced Science, EarlyView.
Li‐ and V‐intercalated V2Se2O bilayers possess intralayer ferrimagnetic and interlayer ferromagnetic orders, alongside ferroelasticity, in‐plane uniaxial magnetic anisotropy, half‐metal/enhanced spin splitting, the anomalous Hall effect, giant magnetoresistance, tunneling magnetoresistance, near‐perfect spin filtering effect, spin Seebeck effect, and ...

POSS Polyimide Composite Sealed Triple‐Junction GaAs Thin‐Film Solar Cell for Long‐Term Low Earth Orbit Serve

Advanced Science, EarlyView.
Ultrathin oxide layer and ultraviolet absorbent are introduced into polyhedral oligomeric silsesquioxane (POSS) polyimide to improve the transmittance conservation and realize near zero mass loss against ultraviolet and atomic oxygen exposures. The POSS polyimide composite sealed triple‐junction GaAs thin‐film solar cell exhibits enhanced endurance of ...

Einstein-Yang-Mills sphalerons and fermion number non-conservation

, 1994
It is argued that the sphaleron solutions appearing in the Einstein-Yang-Mills theory are important in the transition processes at extremely high energies.

A Pull‐Out Mooring Wave Energy Converter: Design, Analysis, and Application

Advanced Science, EarlyView.
A pull‐out mooring wave energy converter (POM‐WEC) with a high‐performance electromagnetic power take‐off system efficiently converts low‐frequency wave excitation into high‐speed rotor motion, enabling reliable energy harvesting in real marine environments.

Time-dependent deformation functional theory

, 2006
We present a constructive derivation of a time-dependent deformation functional theory -- a collective variable approach to the nonequalibrium quantum many-body problem. It is shown that the motion of infinitesimal fluid elements (i.e.

Recursive models for constructive set theories

Annals of Mathematical Logic, 1982
AbstractWe define recursive models of Martin-Löf's (type or) set theories. These models are a sort of recursive realizability; in fact, we show that for implication-free formulae of HAω, satisfaction in the model coincides with mr-HEO realizability. Using an idea of Aczel, we extend the model to a recursive model of the constructive set theories of ...

The Importance of Being Imperfect: Structure and Function of Bacterial Amyloid

Advanced Science, EarlyView.
Functional bacterial amyloids such as CsgA and FapC have been widely studied to understand the relationship between aggregation and function. The recently solved structure of FapC reveals a Greek‐key motif in which extensive hydrogen bonding and packing interactions formed by residues in conserved imperfect repeats stabilize a β‐solenoid core.

Compartmentalized Homeostasis Drives High Bamboo Forest Productivity under Nutrient Imbalance

Advanced Science, EarlyView.
This study reveals how Moso bamboo achieves high productivity despite nutrient‐poor soils. It employs a unique strategy, maintaining strict nutrient balance in its leaves while using woody tissues as flexible storage reservoirs. This compartmentalized mechanism buffers the plant from soil phosphorus limitation and microbial competition, resolving the ...
