With the continuous fermentation of the thought of intelligence, artificial intelligence has extended its tentacles into the field of artistic creation and has begun to try intelligent creation. Painting creation based on artificial intelligence is called "intelligent painting." For oil paintings, the computational language is a relatively complicated description. How to correctly identify the computational language of oil paintings is essential for establishing a large oil painting database. This paper constructs a meaningful learning similarity measure and multiclassification model based on the CCNN model to realize the classification of oil painting language. A cropped CNN model is used to extract language features, and on this basis, oil painting works are cross-compared and multiclassified. This method realizes the classification of oil painting language and the corresponding painter and achieves superior accuracy. This paper constructs a data classification method based on small samples, measures similarity through cross-comparison, and provides a measuring approach for classifying the language of oil paintings. The CCNN model proposed combines the best classification results of oil painting language, which improves the accuracy of oil painting language classification. Moreover, it further enriches the methods of oil painting language classification and image recognition under computational intelligence. [ABSTRACT FROM AUTHOR]

Science and technology innovation (STI) policy is a strategic principle to guide the whole cause of STI. The study on STI policy and its effect is particularly important. Most of the existing studies on the effect of STI policy focus on the effect of a single policy, and the studies on the effect of policy combination and its differences need to be further enriched and improved. This study proposes a method combining system simulation experiment and analysis of variance (ANOVA) to study the differences of combination effects of STI policies. The results show that there are significant effect differences in the combination of STI policies as a whole, but when it comes to different combinations of STI policies, not all policy combinations have significant differences. This study not only points out whether there are significant differences in a certain effect among which combinations of STI policies but also points out whether there are significant differences in all effects among which combinations of STI policies at the same time. This study has theoretical and practical significance for realizing scientific policy-making and sustainable development. [ABSTRACT FROM AUTHOR]

In this study, a case of bilateral common carotid artery occlusion and aneurysm in the V4 segment of the right vertebral artery with constriction of the left vertebral artery is presented. By improving digital subtraction angiography, an elderly female patient with subarachnoid haemorrhage (SAH) was diagnosed with a V4 segment of right vertebral artery aneurysm, a microaneurysm at the beginning of basilar aneurysms, bilateral common carotid artery occlusion, and narrowing vessel of left vertebral artery (DSA). Through the compensation of the basilar artery, the bilateral vertebral arteries provide intracranial and extracranial blood. Because the vertebral artery is narrowed, the right vertebral artery has priority in intracranial and extracranial blood delivery. Many members of the patient's immediate family have vasculitis, which has yet to be proven by appropriate laboratory testing but is thought to be the major cause of big artery occlusion. After cerebral angiography, the major source of this subarachnoid haemorrhage was determined to be a V4 segment of right vertebral artery aneurysm. Endovascular stent-assisted coil embolization was used to treat a V4 section of the right vertebral artery aneurysm. Because the basilar aneurysm was distal to the artery, interventional embolization was difficult to do, and it was not the major cause of the subarachnoid haemorrhage, the patient was advised to have follow-up surveillance, and she recovered well following the procedure. The combination of endovascular intervention of bilateral common carotid artery blockage and V4 segment of right vertebral artery aneurysm yielded excellent clinical outcomes in this instance. Endovascular treatment of a bilateral common carotid artery blockage paired with a V4 segment of a right vertebral artery aneurysm yielded excellent clinical outcomes in this patient, although long-term follow-up is necessary.
