为探讨不同温度处理下蛋黄脂质对小鼠学习认知能力下降的缓解能力的差异。本研究利用小鼠认知障碍模型,比较95℃(水浴30 min)和121℃(灭菌锅加热30 min)热处理蛋黄脂质组分改善小鼠学习认知能力的差异。研究结果表明,相较于121℃热处理的蛋黄脂质,95℃热处理的蛋黄脂质更有效地降低了Tau蛋白的磷酸化和Aβ1-40、GSK-3β表达,下调了促炎因子的表达,其提升小鼠的学习记忆能力的效果更好。95℃热处理蛋黄脂质中的多不饱和脂肪酸以及DHA较121℃热处理的蛋黄脂质显著增加(P<0.05)。因此,过度的加热条件,会破坏蛋品中DHA等多不饱和脂肪酸,削弱蛋黄脂质的改善认知的生物活性。本研究为蛋制品的热加工工艺的优化提供参考依据。

Optoelectronics Letters 2025年第1期21卷 28-34页

作者： ZHAO Shuai ZHOU Ran LUO Mingming liu Jianfei liu Xiongfei ZHOU Tao School of Electronic Information Engineering Hebei University of Technology Tianjin Key Laboratory of Electronic Materials and Devices School of Civil Engineering and Transportation Hebei University of Technology Tianjin Jinhang Institute of Technical Physics

The fiber optic sensing technology provides data support in structural health monitoring of the macro facilities, including design, construction, and maintenance of bridges, tunnels, ports and other infrastructures. In this paper, a distributed vibration sensing system is proved to be responsive to a single touch over a 1.8-m-long equivalent fiber segment, covering a vibration frequency from 5 Hz to 25 kHz. The sensing fiber was arranged as an S type layout on the bridge to recognize the standing state, windblown disturbance, and walking vibration. Moreover, the knocking and climbing events are recognized fiber laying spinning lines and hanging on the fences, respectively. The demonstration shows an accurate positioning and sensitive vibration monitoring applied on the automated three-dimensional(3D) printed bridge, which is applicable to all kinds of 3D printed facilities as intelligent sensory neuro-networks.

A quantum-search-based multi-classifier for image recognition

Science China(Physics,Mechanics & Astronomy) 2025年第1期Mechanics & Astronomy) .卷 21-31页

作者： Lu liu Xingyu Wu Lufan Zhang Chuan Wang School of Artificial Intelligence Beijing Normal University Applied Optics beijing Area Major Laboratory Beijing Normal University

The multi-class classification of images is a pivotal challenge within the realm of image processing. As the volume of visual data continues to expand, there is a burgeoning interest in harnessing the unique capabilities of quantum computation to augment the efficiency of classification tasks. However, many existing methods for training quantum image multi-classifiers parallel classical machine learning techniques, where the requisite circuit measurements increase linearly with the volume of training data. This work introduces a novel approach for training a quantum image multi-classifier based on the quantum search algorithm. We have meticulously conducted rigorous experiments on a handwritten digit dataset, a classic benchmark in the field. The results have been meticulously compared with previous works, and the comparative analysis not only validates the efficiency of our proposed approach, requiring only O(N/b) measurements during training, but also highlights a significant quadratic speedup of the algorithm.

Visualization of the protective role of estrogen against female liver fibrosis via an ER viscosity NIR fluorescent probe

Science China Chemistry 2025年第1期68卷 360-368页

作者： Zheng liu Changyu Zhang Zipeng Li Wanying Ma Jia liu Xiang Xia Ning Xu Wen Sun Jianjun Du Jiangli Fan Xiaojun Peng State Key Laboratory of Fine Chemicals Dalian University of Technology Ningbo Institute of Dalian University of Technology

Endoplasmic reticulum(ER) viscosity has emerged as a new potential biomarker for hepatic fibrosis(HF). Herein, we report the first ER-targeting viscosity-responsive near-infrared(NIR) fluorescent probe HBT-PP for investigations of HF *** twisted intramolecular charge transfer(TICT) and the excited state intramolecular proton transfer(ESIPT) are combined to endow HBT-PP with the selective response towards viscosity(～62-fold) and a super large stokes shift(～320 nm). HBT-PP mainly targets organelle ER and is able to image the drug-or alcohol-induced viscosity elevation in living cells. Significantly,HBT-PP was successfully applied to visualize the gender difference in HF and the protective role of estrogen in restraining HF progression. Of note, after 10 min of stain with HBT-PP, HF lesions showed a stage-based response, indicating the potential of this probe in fast and early diagnosis of HF. These results clearly demonstrated the promising application of HBT-PP as a new tool for exploring ER viscosity-involved physiological and pathological processes.

Study of the internal characteristics of the stall in a centrifugal pump with a cubic non-linear SGS model

引用

Journal of Hydrodynamics 2019年第4期31卷 788-799页

作者： Xian-bei Huang Zhu-qing liu yao-jun Li Wei Yang Qiang Guo School of Hydraulic Energy and Power Engineering Yangzhou University Yangzhou 225127 China College of Water Resources and Civil Engineering China Agricultural University Beijing 100083 China

The stall in a centrifugal pump impeller under a quarter-load condition is investigated by using a third-order SGS model named the DCNM, for a better understanding of the rotation effect on the stall phenomenon. The study of the distributions of the Reynolds stresses, the production tei*m and the rotation term reveals that the production and the rotation jointly result in the non-uniform Reynolds stress distribution. Further study of the two components of the production and the rotation shows that they jointly transport a certain energy from the Reynolds component R、to Ruu.
