AIM:To investigate changes in macular vessels and thickness in myopic eyes after intraocular collamer lens(ICL)implantation using quantitative optical coherence tomography angiography(OCTA).METHODS:This retrospective included 73 myopic eyes of 73 patients(average age,27.53±6.16 y)who underwent ICL implantation(28 eyes were Toric ICL).Axial length(AL),uncorrected visual acuity(UCVA),refractive dioptre(RD),intraocular pressure(IOP)and OCTA were measured and compared with before and 1 wk,1,and 3 mo after *** was used to image vessel density(VD)and skeleton density(SD)in both the superficial(SCP)and deep capillary plexus(DCP).Central retinal thickness(CRT)and ganglion cellinner plexiform layer thickness(GCT)were also *** between pre-and postoperative measurements were analysed by repeated measures analysis of ***:Compared with preoperative data,postoperative data on UCVA revealed significant improvements in all patients(P<0.05).However,there was no significant difference in *** the operation,CRT and GCT exhibited significant changes(P<0.05).Among these measures,CRT was significantly higher at one and three months postoperative(all P<0.01).GCT was significantly higher at 1 wk,1,and 3 mo postoperative(all P<0.01).Changes in VD and SD were nonsignificant in both the SCP and *** was no difference in postoperative changes between the ICL and Toric ICL ***:ICL and Toric ICL implantation both have good efficacy and safety for myopic eyes,but macular area changes that occur after surgery need attention.

Catalyst–support interaction plays a crucial role in improving the catalytic activity of oxygen evolution reaction(OER).Here we modulate the catalyst–support interaction in polyaniline-supported Ni_(3)Fe oxide(Ni_(3)Fe oxide/PANI)with a robust hetero-interface,which significantly improves oxygen evolution activities with an overpotential of 270 mV at 10 mA cm^(-2)and specific activity of 2.08 mA cm_(ECSA)^(-2)at overpotential of 300 mV,3.84-fold that of Ni_(3)Fe *** is revealed that the catalyst–support interaction between Ni_(3)Fe oxide and PANI support enhances the Ni–O covalency via the interfacial Ni–N bond,thus promoting the charge and mass transfer on Ni_(3)Fe *** the excellent activity and stability,rechargeable Zn-air batteries with optimum Ni_(3)Fe oxide/PANI are assembled,delivering a low charge voltage of 1.95 V to cycle for 400 h at 10 mA cm^(-2).The regulation of the effect of catalyst–support interaction on catalytic activity provides new possibilities for the future design of highly efficient OER catalysts.

A dry-electrode enabled ECG-on-Chip with arrhythmia-aware data transmission

Science China(Information Sciences) 2025年

Early detection and treatment of cardiovascular diseases (CVDs) can be significantly enhanced through the use of flexible wearable electrocardiogram (ECG) sensors, potentially reducing CVD-related mortality. This paper introduces an ECG-on-Chip (EoC) solution tailored for flexible ECG sensors, incorporating novel features to address common challenges in wearable ECG technology. The EoC integrates a chopper-stabilized capacitively-coupled instrumentation amplifier (CS-CCIA),ensuring a high common-mode rejection ratio (CMRR) and low noise performance. Performance is further boosted via a positive feedback loop (PFL) and a programmable gain amplifier (PGA) with shared on-chip calibration logic, which enhances input impedance and minimizes gain variability to ensure consistent algorithm performance. Additionally, a secondary chopping technique is employed to further reduce noise, achieving an input-referred noise level of 454 nVrms. The embedded algorithm within the EoC is designed to extract clinically meaningful features, facilitating robust real-time arrhythmia analysis. Fabricated using a 0.18μm CMOS process, the EoC consumes 14.9μW with a supply voltage of 1.2 V. The algorithm’s efficacy has been validated over 0.4 million heartbeats, demonstrating a sensitivity of over 99.7%for R-peak detection and 98.3%for arrhythmia analysis. To demonstrate practical application, the EoC has been integrated with a commercial Bluetooth low energy (BLE)transceiver, forming a wireless arrhythmia monitoring sensor equipped with dry electrodes. This system consumes 292.04μW in arrhythmia-aware transmission mode, supporting 13 days of operation with a 30 mAh thin-film battery.

目的:应用OCT观察ICL植入术后黄斑区节细胞-内丛状层及中央区视网膜厚度的改变,明确ICL植入术对于眼后节的影响。方法:前瞻性研究。最终纳入行ICL植入术患者26例41眼,平均年龄28.19±6.48岁。所有受试者均行眼轴长度(AL)、裸眼视力(UCVA)、综合验光、最佳矫正视力(BCVA)、眼压(IOP)及OCT检查。观察术前及术后的中央区视网膜厚度(CRT)和节细胞-内丛状层厚度(GCT),以及UCVA、BCVA和IOP的变化。结果:ICL植入术后UCVA和BCVA较术前均有提高(P<0.05),而眼压无变化。术前,术后1wk,1、3mo CRT分别为273.20±25.48、274.07±27.64、277.85±25.49、275.99±24.68μm,而GCT分别为85.31±5.19、88.95±6.87、87.73±4.23、87.45±4.59μm(均P<0.05),其中CRT在术后1mo较术前有增加(P<0.01),GCT在术后1wk,1、3mo均比术前有增加(P<0.05)。GCT在术后1wk的变化与AL呈正相关(r s=0.529,P=0.001)。结论:ICL植入术具有良好的有效性及一定的安全性,但术后也会发生一定的黄斑区改变,需给予一定的重视。

Spin-orbit torque （SOT）,as a promising writing method for magnetic random-access memory （MRAM）,has garnered widespread interest for over a decade [1].Heavy metals,such as β-W,have been broadly adopted as spin current sources,but suffer from phase change at a limited thickness,resulting in a dramatic reduction of the charge-tospin conversion efficiency θSH[2].The thickness limitation leads to stringent etching conditions and large distribution among devices,posing challenges for simultaneously satisfying SOT efficiency,etching-stop margins,and back-end-ofline （BEOL） compatibility.
