Mapping the “Supply–Demand–Flow” of Ecosystem Services for Ecosystem Management in China

open access: yesAdvanced Science, EarlyView.
This study develops a “supply–demand–flow” framework clarifies how ecosystem services move between regions by distinguishing potential and actual supply and demand. Using integrated biophysical–socioeconomic modeling, nine services in China were mapped.

Fixed‐Linkage Enabled Ultra‐Stable Ion Transport Channels in Membranes for Long‐Life Alkaline Flow Batteries

open access: yesAdvanced Science, EarlyView.
Rigid fixed‐ethylene‐linked PBI membrane stabilizes ion‐transport channels, enabling high ionic conductivity and durable alkaline Zn─Fe flow batteries. ABSTRACT Alkaline zinc–iron redox flow batteries (Zn─Fe FBs) are promising candidates for developing high‐voltage and cost‐effective grid‐scale energy storage systems.

Pathological role of methionine in the initiation and progression of biliary atresia

open access: yesFrontiers in Pediatrics, 2023
Methionine (Met) is an essential amino acid, and its excessive dietary intake and/or its metabolism disturbance could lead to accumulation/depletion of hepatic Met and some of the key intermediates of these pathways, which would interfere normal liver ...

Local Autonomy in Action: Beijing's Hong Kong and Macau Policies

open access: yesJournal of Current Chinese Affairs, 2013
This paper investigates how Beijing governs its two special administrative regions (SARs) of Hong Kong and Macau through leverages on their local autonomy. First, a conceptual analysis of local autonomy will be provided. Local autonomy is more than a zero-sum game between the central and local authorities over how much power should be granted or taken

Rigid‐Flexible Coupling Units Enable Robust Large Birefringence

open access: yesAdvanced Science, EarlyView.
A rigid–flexible coupling strategy, combining flexible (S3)2− linear units with rigid (VO4)3− tetrahedra, yields Sr4(VO4)2S3—a robust crystal exhibiting large birefringence (Δn = 0.52@550 nm) and remarkable thermal, air, and water stability. ABSTRACT Birefringent crystals are central to polarization control in laser technologies (e.g., wave plates and ...

Kinsenoside Targets IDH1 to Restore Microglial Immune‐Metabolic Homeostasis for Alzheimer's Disease Therapy

open access: yesAdvanced Science, EarlyView.
Dysregulated TCA cycle contributes to Alzheimer's disease (AD) pathogenesis. Here, we show that microglial isocitrate dehydrogenase 1 (IDH1) is a critical driver. Elevated IDH1 disrupts citrate metabolism and mitochondrial function, exacerbating AD pathology.

Patient‐Mounted Neuro Optical Coherence Tomography for Targeted Minimally Invasive Micro‐Resolution Volumetric Imaging in Brain In Vivo

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Herein, a patient‐mounted neuro optical coherence tomography system that integrates a 5 degrees‐of‐freedom skull‐mounted robot (Skullbot) with a 0.6 mm neuroendoscope for targeted, minimally invasive deep brain imaging, is developed. The system offers high‐resolution imaging with precise deployment, demonstrated through successful tumor imaging in a ...

On the Molecular Diffusion Dynamics Between Subcutaneous Tissue and Microneedles for Wearable Continuous Glucose Monitoring

open access: yesAdvanced NanoBiomed Research, EarlyView.
In this study, we investigate the dynamics of glucose diffusion between subcutaneous tissue and hydrogel‐filled microneedles. Specifically, we examine how hydrogel thickness, microneedle size, and glucose concentration influence diffusion. This study provides an experimental reference to the wearable biosensor community researching microneedle‐based ...
