Should We Use a Case-Crossover Design?

, 2000
▪ Abstract  The first decade of experience with case-crossover studies has shown that the design applies best if the exposure is intermittent, the effect on risk is immediate and transient, and the outcome is abrupt.

Tailoring Structure–Property Relationships in π‐Conjugated Heterocyclic Poly(arylene alkylene) Anion‐Exchange Membranes for High‐Performance Water Electrolysis

Advanced Science, EarlyView.
From passive to active ion transport: π‐conjugated heterocycles reconfigure the hydration environment and microphase morphology of p‐terphenyl‐based anion‐exchange membranes, enabling fast hydroxide transport and high‐performance water electrolysis. ABSTRACT Anion‐exchange membrane water electrolysis (AEMWE) is a promising technology for sustainable ...

Association between ambient air pollution and cardiovascular disease mortality: An individual-level case-crossover study in Hefei, China

Ecotoxicology and Environmental Safety
Background: Short-term exposure to air pollution is strongly associated to cardiovascular disease (CVD) mortality; however, detailed studies in rapidly urbanizing areas remain limited.

Elastomeric Core‐Conductive Shell Slurry Additive Stabilizes High‐Voltage NCM811 Cathodes via Mechanical‐Electrical Dual Regulation

Advanced Science, EarlyView.
A core‐shell ASA slurry additive constructs a mosaic‐like interface on high‐voltage NCM811 cathodes. This architecture decouples interfacial functions: the elastomeric core buffers mechanical stress to prevent microcracking, while the conductive shell facilitates rapid ion/electron transport, enabling mechanical‐electrical dual regulation and enhanced ...

Ambient temperature variation (DTR, TCN, and TV

Climate Services
Background: Despite robust evidence linking temperature variation and ambient air pollution to cardiopulmonary mortality, quantitative evidence regarding their effects on pulmonary hypertension (pH) hospitalizations is still scarce.

Spatiotemporal Thermal Modulation and Patterning using a Programmable 1024 Element Microheater Array

Advanced Science, EarlyView.
Programmable microheater arrays are essential for a variety of applications. However, large arrays have thus far not been realized. We introduce a programmable 32×$\times$32 microheater array consisting of heating elements – each smaller than 300 μm$\umu{\rm m}$.

Targeting the CRYAB/β‐Catenin Axis with an MMP‐9‐Responsive Hydrogel Disrupts CTC Clusters to Suppress Progression of Hepatocellular Carcinoma after Radiofrequency Ablation

Advanced Science, EarlyView.
The graphical abstract illustrates that sublethal thermal stress after iRFA upregulates the chaperone CRYAB in residual HCC cells, which stabilizes β‐catenin and drives a dual pathological program, including EMT and N2‐TAN polarization, thereby leading to heterotypic CTC cluster formation. The MMP‐9‐responsive hydrogel (XB@Gel) delivers XAV‐939 and BMS‐
