Robust Integral Consensus Control of Multi‐Agent Networks Perturbed by Matched and Unmatched Disturbances: The Case of Directed Graphs

ABSTRACT This work presents a new method to design consensus controllers for perturbed double integrator systems whose interconnection is described by a directed graph containing a rooted spanning tree. We propose new robust controllers to solve the consensus and synchronization...

Halogen Substitution as a “Chirality Editor” for Amplifying Spin‐Selective Transport in Lead‐Free Metal‐Halide Hybrids

ABSTRACT Lead‐free metal‐halide hybrids hold promise as flexible semiconductors for X‐ray detection, but their application is constrained by inefficient carrier transport. Here, we introduce halogen substitution on chiral molecular cations as a “chirality editor” to modulate the...

Programming Ion‐Engineered Interphase for Practical Zinc Batteries Through Exogenous Cation‐Anion Synergy Chemistry

ABSTRACT A stable anode‐electrolyte interface is vital for battery cycling. Translating the successful anion‐derived interphase paradigm from Li‐ion to aqueous Zn‐ion batteries (ZIBs) is hindered by narrow electrochemical windows and chaotic interfacial reactions. Here we overcom...

Psychological and Educational Outcomes of Chinese Rural Migrant Youths in Urban Schools: A Person-Centered Examination of Cross-Time Transitions

Abstract This study adopts a person-centered approach to examine how profiles of relationships with parents, teacher recognition, and peer relationships conjoin and influence the academic and psychological wellbeing of Chinese migrant adolescents. Drawing upon two-wave data from...

Delivering building demand flexibility for grid-interactive operation: from perception and cognition to decision, execution, and verification

As both buildings and power systems undergo rapid decarbonization, demand flexibility (DF) in buildings has emerged as a key enabler for renewable energy integration, grid reliability, energy resilience, and efficient and low carbon operation. By dynamically adjusting building en...

Multiple-adverse health conditions, mental health, and health-related quality of life in stroke survivors: Latent profile analysis and mediation analysis

Objective This study aimed to identify subgroups of stroke survivors based on multiple-adverse health conditions and determine the potential mediation effects of mental health in their relationship with health-related quality of life. Design A cross-sectional study. Setting Three...

Generation and Dynamics of Reconfigurable Kerr Combs via Multimode Self‐Injection Locking

ABSTRACT Microresonator‐based Kerr combs provide a promising bridge directly linking the microwave and the optical frequency domain, bringing revolutions in optical metrology, spectroscopy, and frequency synthesis. Although self‐injection locking (SIL) has emerged as a powerful t...

Micromechanical Analysis of Methane Hydrate-Bearing Sediments During Gas Extraction Considering Hydrate Dissociation and Particle Breakage

With the growing interest in methane hydrate exploitation, numerous studies have been focusing on methane hydrate-bearing sediments (HBS). Depressurization is recognized as an effective method for gas extraction from HBS. However, the microscale mechanical behavior of HBS during...

From herbal cuisine to lasting memory: dining experiences in traditional Chinese medicine diet restaurants

Purpose Drawing on stimulus–organism–response theory, this study developed a memorable dining experience model linking four restaurant attributes (food, service staff food recommendations, service quality and atmospherics) to memorable dining experiences, revisit intentions, and...

Spontaneous ChlorineGeneration via Interfacial Oxidationof Chloride by O2 on Acidic Microdroplets

Abstract Reactive chlorine species significantly influence atmospheric chemistry, yet their sources remain inadequately defined. We have discovered a spontaneous formation pathway for substantial molecular chlorine (Cl2) from the oxidation of chloride (Cl–) through interfacial ox...

Nanoscale Formation,Structure, and Stability of Phosphate-IronColloids at Anoxic-Oxic Interfaces

Abstract The mobility of phosphorus (P) at anoxic–oxic interfaces is largely controlled by the formation of phosphate-iron (Fe) colloids, yet the nanoscale mechanisms underlying their formation, structure, and stability remain poorly described. Here, we systematically investigate...

AOPQ-Net Acoustic–Optical Proposal Query Network for Underwater Multimodal Object Detection

Optical cameras and imaging sonars are widely used sensors in autonomous underwater vehicles. However, their different imaging mechanisms introduce substantial cross-modal discrepancies in the acquired data. In addition, underwater optical images are often degraded by low illumin...

Beyond the surface: uncovering trainee translators’ reading processes during GenAI translation quality evaluation tasks

This study examines the influence of text genre, i.e. literary and tourism texts, and prompting techniques, specifically Chain-of-Thought (CoT) reasoning and Domain-Specific Prompts (DSP), on trainee translators’ reading processes when evaluating GenAI-generated translations. Dra...

Exploring the attributes of organizational health literacy in Chinese healthcare institutions from the perspective of the social-ecological theoretical model: a grounded theory study
