Turbulence‐Intensity Effects on the Aerodynamic Performance of an H‐Type Darrieus Wind Turbine: A URANS Parametric Study

open access: yesEnergy Science &Engineering, EarlyView.
Turbulence intensity from 1% to 25% was parametrically tested on a three‐bladed H‐type Darrieus rotor across five tip speed ratios (TSRs) using two‐dimensional URANS. The optimal TSR proved the most efficient and most robust operating point simultaneously, with Cp losses capped at 5.8% even at TI = 25%. ABSTRACT The effect of inlet turbulence intensity

Influencing nonmonotonic reasoning by modifier strength manipulation

open access: yes, 2004
Despite the current belief that much common sense reasoning is nonmonotonic in nature, research indicates that only a limited percentage of people are good at nonmonotonic reasoning.

Bio‐inspired vision: From principle, material architectures to system‐level integration

open access: yesFlexMat, EarlyView.
This review introduces the development and mechanism of electronic and ionic bio‐inspired vision devices respectively. Then, it explores the impact of structure on bio‐inspired visual performance from the scale of intrinsic materials and device. Finally, it concludes that only by combining advanced software and technology can more complex vision ...

Organic electrochemical transistors for neural recording and modulation: From mixed‐conduction physics to closed‐loop biointerfaces

open access: yesInfoMat, EarlyView.
OECT‐based neural interfaces integrate mixed ionic‐electronic transduction, soft biointegration, multimodal sensing, and closed‐loop modulation, enabling adaptive recording, neurochemical monitoring, and intelligent therapeutic strategies. Abstract Next‐generation neural interfaces increasingly aim to couple neural recording with local processing and ...

Executable Temporal Logic for Nonmonotonic Reasoning

open access: yes, 1996
this paper we view nonmonotonic reasoning as a (special kind of) process. As temporal logic is a common formalism to specify and derive properties of processes, we introduce a variant of temporal logic as a general specification language for reasoning ...

Implementing Nonmonotonic Reasoning From Weakly Consistent Conditional Belief Bases

open access: yesProceedings of the International Florida Artificial Intelligence Research Society Conference
In this paper, we develop implementations of nonmonotonic reasoning from conditional belief bases that may contain both defeasible and undefeasible, strict beliefs.

Mechanical memory in aging: From adaptive sensing to pathological entrenchment

open access: yesInterdisciplinary Medicine, EarlyView.
Mechanical memory in aging operates through four temporal tiers, from cytoskeletal remodeling to metabolic reprogramming. Aging disrupts this cascade through three distinct decoupling patterns: sensor degradation, conduction blockade, and execution failure, leading to irreversible pathological entrenchment across multiple organ systems.

Heavy‐Metal‐Free Colloidal Quantum Dots for Photocatalysis

open access: yesSmall, EarlyView.
Heavy‐metal‐free colloidal quantum dots provide sustainable photocatalytic platforms by combining tunable band structures, strong light absorption, and programmable surfaces/interfaces. This Review highlights how core/shell engineering, alloying, defect regulation, ligand design, and hybrid‐interface construction direct charge separation and ...
