Miniaturized Multifunctional Valves for Intelligent Pneumatic Systems in Soft Robotics

Advanced Intelligent Systems, EarlyView.
Miniaturized multifunctional pneumatic valves in normally closed (NC) and normally open (NO) configurations enable reconfigurable and programmable fluidic logic—including AND, OR, NAND, and NOR gates—with/without physical replumbing. These valves integrate sensing, logic, and actuation within a unified architecture, demonstrated through an electronics ...

FISCAL DECENTRALIZATION AND FISCAL AUTONOMY IN THE EU MEMBER STATES [PDF]

In the process of fiscal decentralization sub-central governments have gained access to different fiscal resources, but the autonomy in setting the taxes is a key issue when analyzing the degree of decentralization.

Controlled Hydrogen Delivery by Single‐Atom Ru Accelerates Electrocatalytic Ammonia Synthesis

Angewandte Chemie, EarlyView.
Single Ru atoms anchored on Co3O4 guide reactants along a hydrogen‐rich surface pathway, enabling efficient and selective conversion of NO to NH3. By linking atomic design to catalytic performance, this strategy clarifies the reaction mechanism and offers a versatile platform for engineering oxide catalysts for electrochemical ammonia synthesis ...

Graph Neural Network‐Based Reinforcement Learning for Decentralized Multi‐Robot Manipulation

Advanced Intelligent Systems, EarlyView.
Robot arms lifting a large object face a trade‐off: centralized controllers explode in parameters, while decentralized ones cannot coordinate. A GNN resolves this—each arm runs its own network but acts on the full team state, achieving centralized‐level coordination with decentralized execution. Trained across team sizes, a single policy scales to four‐

Decentralization: Panacea or Pandora’s Box? Fiscal Perversity in Mexico. [PDF]

Advocacy for decentralization has grown in Mexico at a rapid pace during the last decade. The gains of decentralization, however, are rather unclear and many times the assumptions and the outcomes of the process depart from the standard theory of fiscal ...

Modulating Covalent Organic Framework Nanochannel Microenvironments for Sustainable Hydrogen Peroxide Photosynthesis

Angewandte Chemie, EarlyView.
Alkoxy side chains regulate hydrazone‐linked COF nanochannel microenvironments by tuning pore polarity, reactant adsorption, and charge‐separation behavior. The optimized framework facilitates oxygen activation and hydrogen peroxide photosynthesis in real water and a 1 L natural‐sunlight reactor. LCA further shows that natural sunlight and larger‐scale

Risk management externalities in agrifood supply chains

American Journal of Agricultural Economics, EarlyView.
Abstract Firms may under‐ or over‐invest in risk management from the social planner's perspective, resulting in a negative externality on other economic agents in the supply chain. The externality of risk management is particularly relevant for agrifood supply chains, which frequently experience disruptions and play a primary role in preventing major ...
