A Smart Bio‐Battery Facilitates Diabetic Bone Defect Repair Via Inducing Macrophage Reprogramming and Synergistically Modulating Bone Remodeling Coupling

open access: yesAdvanced Functional Materials, EarlyView.
This research presents a novel implantable bio‐battery, GF‐OsG, tailored for diabetic bone repair. GF‐OsG generates microcurrents in high‐glucose conditions to enhance vascularization, shift macrophages to the M2 phenotype, and regulate immune responses.

Universal Neuromorphic Element: NbOx Memristor with Co‐Existing Volatile, Non‐Volatile, and Threshold Switching

open access: yesAdvanced Functional Materials, EarlyView.
A W/NbOx/Pt memristor demonstrates the coexistence of volatile, non‐volatile, and threshold switching characteristics. Volatile switching serves as a reservoir computing layer, providing dynamic short‐term processing. Non‐volatile switching, stabilized through ISPVA, improves reliable long‐term readout. Threshold switching operates as a leaky integrate

Single‐Crystalline Lateral p‐SnS/n‐SnSe van der Waals Heterostructures by Vapor Transport Growth with In Situ Bi Doping

open access: yesAdvanced Functional Materials, EarlyView.
In‐situ doping during growth of SnSe and subsequent attachment of SnS produces high‐quality lateral pn‐heterojunctions between van der Waals semiconductors. Electron beam induced current measurements demonstrate electrically active pn‐junctions, paving the way for devices that harness charge separation at lateral interfaces in layered heterostructures.

Facet‐Engineered S‐Scheme Heterostructure With Enhanced Active Sites for Efficient Photocatalytic Degradation of Organic Contaminants

open access: yesAdvanced Functional Materials, EarlyView.
The facet‐engineered ZnO/Zn3In2S6 heterostructure, dominated by {001} plane coupling, exposes abundant unsaturated Zn sites with elongated Zn─O bonds, directing photoexcited charge carriers along an S‐scheme pathway and suppressing recombination. Enhanced interfacial Zn adsorption toward bisphenol A and methylene blue further synergistically promotes ...

On the Chi square and higher-order Chi distances for approximating f-divergences

open access: yes, 2013
We report closed-form formula for calculating the Chi square and higher-order Chi distances between statistical distributions belonging to the same exponential family with affine natural space, and instantiate those formula for the Poisson and isotropic ...

Artificial Intelligence as the Next Visionary in Liquid Crystal Research

open access: yesAdvanced Functional Materials, EarlyView.
The functions of AI in the research laboratory are becoming increasingly sophisticated, allowing the entire process of hypothesis formulation, material design, synthesis, experimental design, and reiterative testing to be automated. In our work, we conceive how the incorporation of AI in the laboratory environment will transform the role and ...

Towards a Law of Invariance in Human Concept Learning [PDF]

open access: yes, 2011
Invariance principles underlie many key theories in modern science. They provide the explanatory and predictive framework necessary for the rigorous study of natural phenomena ranging from the structure of crystals, to magnetism, to relativistic ...

Maximum likelihood estimation in log-linear models

open access: yes, 2012
We study maximum likelihood estimation in log-linear models under conditional Poisson sampling schemes. We derive necessary and sufficient conditions for existence of the maximum likelihood estimator (MLE) of the model parameters and investigate ...

Metal–Organic Frameworks for Gaseous Pollutant Management: From Capture to Neutralization and Reutilization

open access: yesAdvanced Functional Materials, EarlyView.
This review maps how MOFs can manage hazardous gases by combining adsorption, neutralization, and reutilization, enabling sustainable air‐pollution control. Covering chemical warfare agent simulants, SO2, NOx, NH3, H2S, and volatile organic compounds, it highlights structure‐guided strategies that boost selectivity, water tolerance, and cycling ...

Inconsistency of Pitman-Yor process mixtures for the number of components [PDF]

open access: yes, 2013
In many applications, a finite mixture is a natural model, but it can be difficult to choose an appropriate number of components. To circumvent this choice, investigators are increasingly turning to Dirichlet process mixtures (DPMs), and Pitman-Yor ...
