Purpose Since 1978, China has made tremendous economic achievements through industrial upgrading. However, these are accompanied by an expanding income gap between rural and urban areas. The purpose of this paper is to examine the relationship structure urban–rural inequality in China. Design/methodology/approach Using fixed-effects model provincial data for period 1985–2019, estimates a linear inequality. By decomposing total into four components, then analyzes how affects each component....

Precise recognition and delineation of tumors play a pivotal role in the radiotherapy non-small cell lung cancer (NSCLC). The current manual techniques used clinical practice are both time-consuming labor-intensive. While some studies have made progress automating segmentation targets, there is still room for further improvement their effectiveness. present study introduces unique two-stage deep learning (DL) method. Computed tomography (CT) images two hundred NSCLC cases collected to train...

Abstract Data processing through artificial synapses is gaining attention owing to the emergence of neuromorphic computing. Analog via these can simultaneously handle large volumes data; however, it susceptible interference from various environmental factors. Specifically, temperature changes significantly affect overall signal characteristics, leading substantial errors. Herein, an organic heterojunction‐based synapse presented that capable light–temperature antagonistic operations. The...

In this work, cristobalite seeds were doped in silica-based ceramic cores, and the effect of particle size on properties cores was investigated. With decreasing seeds, content crystallised sintered increased gradually due to elevated surface area; linear shrinkage, bulk density leachability exhibited drastic increase after gradual decrease, flexural strength displayed an opposite tendency. When mean is 5 μm, showed optimal comprehensive properties, including shrinkage 0.35%, apparent...
