As the earliest geographical unit of human activities, river basins have nurtured civilizations with distinct local characteristics. The "human-water relationship" is a key aspect of "human-environment interaction," driving the evolution of urban and rural systems through human adaptation to water. Using Yichang as a case, this paper analyzes population and land use changes to explore the evolution of its "mountain-water-city" spatial pattern. Yichang grows incrementally along the river, forming a compact multi-cluster layout. At the same time, influenced by the significant and special event of the Three Gorges Project construction, the city has undergone rapid "leapfrog" development. Amid population mobility and river basin management needs, Yichang should use its "water" feature to integrate function, scale, and structure, focusing on water protection and utilization to ensure national and energy security. Secondly, amidst the general trend of declining total population and slowing growth, it is necessary to reasonably guide the aggregation and distribution of population within urban spaces based on the resource carrying capacity of each river basin. Finally, Yichang should break linear development inertia, focus on dual city centers, and redirect leading industries from rivers/roads to the eastern industrial city. © 2025 The Author(s)

Experimental Study on the Change Rule of Typical Defective Discharge Characteristics of Transformer Oil Paper Under the Action of Oil Flow Fiber Impurity Particles

IEEE Access 2025年 13卷 35829-35836页

This paper addresses the issue of fiber impurity particle movement and accumulation on the surface of the electrode at the outlet of the converter transformer during long-term operation, which leads to changes in various local discharge characteristics and mechanisms in the insulating oil. An oil flow device experimental platform was constructed to study the discharge characteristics of fiber impurity particles under different particle concentrations, electrode spacings, and insulating medium conditions. The study found that: 1) The higher the concentration of fiber impurities in the contaminated insulating oil, the easier it is for a complete "impurity bridge"to form between the electrodes. At the same time, the discharge quantity associated with the accumulation of impurities also increases. 2) When the concentration of fiber impurities in the contaminated insulating oil is fixed, as the electrode spacing increases, the number of continuous "fiber impurity bridges"formed between the electrodes decreases sharply, while the discharge quantity increases dramatically. As the thickness of the insulating paperboard increases, the accumulation of fiber impurity particles is reduced, and the discharge signal gradually strengthens. © 2013 IEEE.

The Double Stator Magnetic Field Modulation Motor (DSMFMM) realizes the magnetic field modulation effect and optimizes the torque ripple effect by accurately optimizing the flux line. In order to further explore the influence of permanent magnets (PMs) magnetization model on the performance of DSMFMM, this paper conducts a comparative study on the performance of three motors with radial magnetization, Halbach magnetization, and Spoke magnetization. Firstly, three motor models are designed based on the same outer radius and axial length, and the flux lines of the three motors are analyzed in detail. Secondly, the static and dynamic performances of the three models are compared by finite element analysis (FEA) method. Compared with the conventional radial magnetization structure, the DSMFMM structure with Halbach magnetization and Spoke magnetization improves the output torque and torque density of the motor. © 2025, Electromagnetics Academy.

Controllable and scalable preparation of green nucleation seeding accelerator for cement with inert waste stone chips: Role of amorphization

Nucleation seeding is a novel method for accelerating the hydration and improving the early strength of cement-based composites without negative effects. However, the large-scale production of nucleation seeds is usually restricted by the need to control the costs, including that of raw materials, energy consumption, and preparation techniques. In this study, a controlled and large-scale preparation method for sustainable nucleation seeding additives was developed. A stone chip nucleation seed (SC seed) with a D50 of approximately 285 nm was produced from inert waste stone chips using industrial-grade wet grinding equipment. The prepared SC seeds showed excellent accelerating effects within three days, which shortened the final setting time of the cement by 55 % and improved the one-day compressive strength by 98 %. In addition to the ultrafine particle size, amorphization and ion dissolution are essential factors for excellent early strength acceleration. Amorphization of the SC seeds mainly occurs after the mechanochemistry fails to effectively refine the particle size. Furthermore, the amorphization transition gives the inert SC the ability to react with the aluminate phase to form mono or hemicarbonate products, which facilitates the stabilization of ettringite and contributes to the mechanical strength. It was also found that the SC seed had a more notable influence on the nucleation and crystal growth processes, and the bridging effect of the SC seed contributed to the continued acceleration of the hydration rate during the diffusion stage. © 2025

On-chip deep residual photonic neural networks using optical-electrical shortcut connections

Optics Letters 2025年第3期50卷 860-863页

On-chip photonic neural networks (PNNs) have recently emerged as an attractive hardware accelerator for deep learning applications. However, deep PNNs with higher inference complexity are harder to train due to gradient vanishing and exploding problems. In this work, we propose an on-chip deep residual photonic neural network architecture (Res-PNN), which enables the training of deeper PNNs by using optical-electrical shortcut connections. The opticalelectrical shortcut connection is designed using a power splitter, a wavelength demultiplexer, and photodetectors to directly connect the input and the output across optical weight layers. This optical-electrical shortcut connection alleviates the gradient vanishing and exploding problems by providing a direct path for gradient backpropagation, ensuring stable training of deeper PNNs. The proposed Res-PNN achieves classification accuracies of 88.4% on the CIFAR-10 dataset and 80.3% on the CIFAR-100 dataset. Compared to fully connected PNNs, Res-PNN improves classification accuracy by 3.2% on the CIFAR-10 dataset and 11.3% on the CIFAR-100 dataset. © 2025 Optica Publishing Group.
