The rapid developments of unmanned aerial vehicles(UAV)and vision sensor are contributing a great reformation in precision *** can fly their UAV spraying pesticides around their crop fields while staying at their remote control room or any place that is separated from their farm ***,there is a common phenomenon in rice planting management stage that some empty areas are randomly located in ***,a critical problem is that the waste of pesticides that occurs when spraying pesticides over rice fields with empty areas by using the common UAV,because it is difficult to control the flow accuracy based on the empty areas *** tackle this problem,a novel vision-based spraying system was proposed that can identify empty areas automatically while spraying a precise amount of pesticides on the target *** this approach,the image was preprocessed with the Lucy-Richardson algorithm,then the target area was split from the background with k-means and the feature parameters were extracted,finally the feature parameters were filtered out with a positive contribution which would serve as the input parameters of the support vector machine(SVM)to identify the target *** a fuzzy control model was analyzed and exerted to compensate the nonlinearity and hysteresis of the variable rate spraying *** results proved that the approach was applicable to reducing the amount of pesticides during UAV spraying,which can provide a reference for precision agriculture aviation in the future.

Based on the endogenous technology progress framework for late-moving large countries,this paper simulates the effects of market size on technology progress path and technology catch-up,and finds that under the strategy of combining innovation with imitation,the increase of market size will restrain the convergence of economies towards technology frontier and deepen their reliance on *** the strategy of replacing imitation with innovation,there is a non-uniform U-shaped threshold effect for market size to influence technology progress path and catch-up,and the threshold for the shift of technology progress path lags behind that for technology ***,we should follow technology catch-up as the benchmark and timely adjust our innovation strategy to unleash the advantages of economies of scale for *** innovation-driven development strategy is a choice compatible with China’s changing market ***,since China remains in a transition from a super-large economy to a super-strong one,the contribution of innovation will decrease at first before increasing afterwards.

ObjectiveThis review aimed to summarize the role of the Hippo signaling pathway in renal cell carcinoma (RCC), a urologic malignancy with subtle initial symptoms and high mortality rates due to metastatic RCC. The Hippo signaling pathway, which regulates tissue and organ sizes, plays a crucial role in RCC progression and metastasis. Understanding the involvement of the Hippo signaling pathway in RCC provides valuable insights for the development of targeted therapies and improved patient *** this review, we explored the impact of the Hippo signaling pathway on RCC. Through an analysis of existing literature, we examined its role in RCC progression and metastasis. Additionally, we discussed potential therapeutic strategies targeting the Hippo pathway for inhibiting RCC cell growth and invasion. We also highlighted the importance of investigating interactions between the Hippo pathway and other signaling pathways such as Wnt, transforming growth factor-beta, and PI3K/AKT, which may uncover additional therapeutic *** Hippo signaling pathway has shown promise as a target for inhibiting RCC cell growth and invasion. Studies have demonstrated its dysregulation in RCC, with altered expression of key components such as yes-associated protein/transcriptional coactivator with PDZ-binding motif (YAP/TAZ). Targeting the Hippo pathway has been associated with suppressed tumor growth and metastasis in preclinical models of RCC. Furthermore, investigating crosstalk between the Hippo pathway and other signaling pathways has revealed potential synergistic effects that could be exploited for therapeutic *** the role of the Hippo signaling pathway in RCC is of paramount importance. Elucidating its functions and molecular interactions contributes to RCC diagnosis, treatment, and the discovery of novel mechanisms. This knowledge informs the development of innovative therapeutic strategies and opens new avenues for research

作者： wang linhui wang Zhixiang Sun Yinghao Department of Urological Surgery Changhai Hospital Second Military Medical University Shanghai 200433 China

To differentiate renal oncocytoma from renal carcinoma, the clinical data of four patients with incidentally found renal oncocytomas were studied in this report. And additional Immunohistochemistry examinations were done to confirm diagnosis. Renal oncocytomas were found incidentally in four patients during medical examination. No characteristic changes were found in laboratory tests. Radiology examination provided the location and possibility of renal oncocytoma. History, laboratory test and radiology exanimation indicated the diagnosis of renal oncocytoma, but the final identify of renal oncocytoma need pathology examination.
