Blind-label subwavelength ultrasound imaging.

There is a long-existing trade-off between the imaging resolution and penetration depth in acoustic imaging caused by the diffraction limit. Most existing approaches addressing this trade-off require controlled "labels," i.e.

Fibroblast growth factor 23 and outcomes of atrial fibrillation: from clinical association to genetic evidence.

Aims: Fibroblast growth factor 23 (FGF23) has been implicated in the occurrence of atrial fibrillation (AF), but its prognostic value in AF patients remains unclear.

Methods And Results: A total of 35 197 AF patients with available follow-up data (3.56, 0.

Regulating Interphase Chemistry by Targeted Functionalization of Hard Carbon Anode in Ester-based Electrolytes for High-Performance Sodium-Ion Batteries.

Commercial hard carbon (HC) anode suffers from unexpected interphase chemistry rooted in the parasitic reactions between surface oxygen-functional groups and ester-based electrolytes. Herein, an innovative strategy is proposed to regulate interphase chemistry by tailoring targeted functional groups on the HC surface, where highly active undesirable oxygen-functional groups are skillfully converted into a Si-O-Si molecular layer favorable for anchoring anions. Then, an inorganic/organic hybrid solid electrolyte interphase with low interfacial charge transfer resistance and enhanced cycling durability is constructed successfully.

Neurotransmitters crosstalk and regulation in the reward circuit of subjects with behavioral addiction.

Behavioral addictive disorders (BADs) have become a significant societal challenge over time. The central feature of BADs is the loss of control over engaging in and continuing behaviors, even when facing negative consequences. The neurobiological underpinnings of BADs primarily involve impairments in the reward circuitry, encompassing the ventral tegmental area, nucleus accumbens in the ventral striatum, and prefrontal cortex.

Data-driven and model-guided iterative reconstruction framework for simultaneous sparse-view and ring artifact reduction in synchrotron X-ray microtomography.

Synchrotron X-ray microtomography (S-µCT) is a highly valuable technique for investigating organ function and pathologies. However, its application is often limited by high radiation doses and the occurrence of ring artifacts. While S-µCT utilizing sparse-view projections can effectively decrease radiation doses, the reconstructed images frequently exhibit severe streaking artifacts, which are exacerbated by ring artifacts, ultimately compromising reconstruction accuracy, image quality, and resolution.
