This article examines the late Qing urban transformation as a conscious effort by reformist officials, like Zhang Zhidong, to confront imperialist expansion and the challenges of the treaty port system during the dynasty＇s last decades. It shows how ＂commercial warfare （shangzharo＂ thought among the urban, reformist elite provided impetus for the radical transformation of traditional cities from military and administrative centers to battlefields of commercial warfare （shangzhan） against the West. No place better illustrates the urban structural changes in the late Qing dynasty than the tri-cities of Wuchang, Hanyang, and Hankou, the base of Zhang Zhidong＇s late Qing reform in Hubei. Zhang＇s daring urban modernizing efforts replaced the hierarchical structure of the three cities with relatively equal and symbiotic relationships. More importantly, Zhang Zhidong resurrected the concept of shangzhan （commercial warfare）--the idea that China could fight foreign expansion through commercial competition, which Zeng Guofan first used to address Western commercial advancement in the 1860s. This thought enabled Zhang to use the increasing global pressure and Chinese nationalistic sentiments to advance his reform agenda and break from the restrictions of the traditional urban ideal. Analyzing the intellectual foundations of late Qing urban reform is also crucial to understanding cities＇ central position in Qing＇s defensive global engagement.

The kinetic process of a slow oxygen evolution reaction (OER) always constrains the efficiency of overall water electrolysis for H2 *** particular,nonprecious metal electrodes for the OER have difficulty in possessing excellent electrocatalytic activity and stability in pH-universal media *** this work,urea is first used as a pore-forming agent and active C/N source to fabricate a nanoporous NiFeCoCN medium-entropy alloy (MEA) by high-temperature sintering based on the nanoscale Kirkendall *** NiFeCoCN MEA achieves an overpotential of 432 mV at a current density of 10 mA·cm^(-2) and a lower Tafel slope of 52.4 mV·dec^(-1) compared to the IrO_(2)/Ti electrode (58.6 mV·dec^(-1)) in a 0.5 mol/L H_(2)SO_(4) *** a 1 mol/L KOH solution,the NiFeCoCN MEA obtains an overpotential of 175 mV for 10 mA·cm^(-2) and a Tafel slope of 40.8 mV·dec^(-1),which is better than IrO_(2)/Ni *** work proves a novel strategy to design and prepare nanoporous MEA materials with desirable C/N species,which provides promising prospects for the industrial production of H2 energy.

The attention mechanism can extract salient features in images,which has been proved to be effective in improving the performance of person re-identification(Re-ID).However,most of the existing attention modules have the following two shortcomings:On the one hand,they mostly use global average pooling to generate context descriptors,without highlighting the guiding role of salient information on descriptor generation,resulting in insufficient ability of the final generated attention mask representation;On the other hand,the design of most attention modules is complicated,which greatly increases the computational cost of the *** solve these problems,this paper proposes an attention module called self-supervised recalibration(SR)block,which introduces both global and local information through adaptive weighted fusion to generate a more refined attention *** particular,a special"Squeeze-Excitation"(SE)unit is designed in the SR block to further process the generated intermediate masks,both for nonlinearizations of the features and for constraint of the resulting computation by controlling the number of ***,we combine the most commonly used Res Net-50 to construct the instantiation model of the SR block,and verify its effectiveness on multiple Re-ID datasets,especially the mean Average Precision(m AP)on the Occluded-Duke dataset exceeds the state-of-the-art(SOTA)algorithm by 4.49%.

This work reports that the flame oscillation induced by acoustic excitation can effectively suppress soot generation in Rijke-type *** the acoustic frequency is close to the natural frequency of the burner system,it can produce resonance resulting in intense oscillation of the *** relationship between the soot suppression efficiency and the acoustic field of standing wave at different flame positions is *** with that under self-excited oscillation,when there is external forced acoustic force introduced to the flame,oscillation combustion occurred in a lager zone in the glass *** fundamental cause of different soot suppression efficiency at different positions is that the standing wave acoustic field causes the particles to move at different speeds in different positions of the glass *** axial particle velocity difference results in the formation of acoustic vortexes and the change of the flame *** high particle velocity causes the air in the glass tube to turn into the turbulent condition and make the flame temperature *** results show that the surface growth rate of soot is reduced,while the oxidation rate of soot is enhanced,which result in the soot suppression under acoustic *** study can provide some reference for the practical application of oscillate combustion in soot suppression.

Development of a highly efficient and stable non-noble metal electrocatalyst for hydrogen evolution is one of the most promising ways to face the energy crisis. In this paper, a facile molten salt method to synthesize nano-silky nickle-doping in molybdenum carbide integrated with carbon black on the carbon fiber paper(MoC-Ni/CFP) as efficient electrocatalytic is developed. The nano-silky structure greatly increases the specific surface area of the material, thereby providing more active sites for hydrogen evolution reaction(HER). In addition,
