Background Determining how an image is visually appealing is a complicated and subjective task. This motivates the use of a machine-learning model to evaluate image aesthetics automatically by matching the aesthetics of the general public. Although deep learning methods have successfully learned good visual features from images,correctly assessing the aesthetic quality of an image remains a challenge for deep learning. Methods To address this, we propose a novel multiview convolutional neural network to assess image aesthetics assessment through color composition and space formation(IAACS). Specifically, from different views of an image––including its key color components and their contributions, the image space formation, and the image itself––our network extracts the corresponding features through our proposed feature extraction module(FET) and the Image Net weight-based classification model. Result By fusing the extracted features, our network produces an accurate prediction score distribution for image aesthetics. The experimental results show that we have achieved superior performance.

Cancer Drug Resistance 2022年第4期5卷 954-970页

Cancer is one of the most harmful diseases in the world, which causes huge numbers of deaths every year. Manydrugs have been developed to treat tumors. However, drug resistance usually develops after a period of time,which greatly weakens the therapeutic effect. Tumor drug resistance is characterized by blocking the action ofanticancer drugs, resisting apoptosis and DNA repair, and evading immune recognition. To tackle tumor drugresistance, many engineered drug delivery systems (DDS) have been developed. Metal-organic frameworks(MOFs) are one kind of emerging and promising nanocarriers for DDS with high surface area and abundant activesites that make the functionalization simpler and more efficient. These features enable MOFs to achieveadvantages easily towards other materials. In this review, we highlight the main mechanisms of tumor drugresistance and the characteristics of MOFs. The applications and opportunities of MOF-based DDS to overcometumor drug resistance are also discussed, shedding light on the future development of MOFs to address tumor drugresistance.

Objective:To analyze the effectiveness of personalized 3D-printed rehabilitation orthotics in the postoperative recovery of jaw ***:Relevant data were collected from 42 patients with jaw fractures treated at our hospital between October 2017 and May *** were randomly divided into a traditional group(n=17)and a modified group(n=25).The traditional group received standard rehabilitation methods,while the modified group used personalized 3D-printed rehabilitation orthotics combined with improved rehabilitation *** temporomandibular disability index(TDI),quality of life scores,postoperative recovery excellence rate,and mouth opening were compared between the two groups at different follow-up times(before rehabilitation,and at 1 week,3 months,and 6 months post-surgery).Results:At 1 week,3 months,and 6 months post-surgery,the TDI in both the traditional and modified groups was significantly lower than before rehabilitation,with statistically significant differences(P<0.05).At 3 and 6 months post-surgery,the TDI in the modified group was lower than in the traditional group,with statistically significant differences(P<0.05).At 3 and 6 months post-surgery,pain,appearance,activity,recreation,work,chewing,swallowing,speech,shoulder function,and total quality of life scores in both groups were higher than before rehabilitation,with the modified group showing significantly higher scores in pain,appearance,chewing,swallowing,and total quality of life(P<0.05).Compared to before rehabilitation,mouth opening significantly improved in both groups at 3 and 6 months post-surgery,with the modified group showing significantly greater improvement(P<0.05).Conclusion:Personalized 3D-printed rehabilitation orthotics are highly effective in the postoperative recovery of jaw *** can improve patients’quality of life after surgery,enhance the excellent rate of postoperative recovery,and increase mouth opening.

Large amounts of volcanic debris-avalanche deposits, which take the shape of hummocks, are distributed around the peripheries of the Laoheishan volcano and Huoshaoshan volcano in Wudalianchi World Geopark. In earlier times, they were called "satellite volcanoes", namely, freestanding volcanoes. This paper points out that these deposits actually came from the collapse of the cones of these two volcanoes. When the lava flow spilled out at the base of the slope of the cones, the slope broke up and collapsed under the action of gravity. Later, ravines were formed on the slope. Caved slope clastics, accompanying lava flow, accumulated at the rims of the volcano cones. Although some accumulations may form very large cones, they are not volcanoes, but deposits of volcanic debris avalanches.

The heterogeneity and diversity of tumors seriously attenuate the curative outcome of single treatment *** therapy has been demonstrated to be a promising candidate to enhance therapeutic efficacy compared with *** an emerging therapeutic strategy,chemodynamic therapy(CDT) has drawn extensive attention in recent ***,the therapeutic efficiency of CDT is still unsatisfying because the level of intracellular hydrogen peroxide(HO) restricts the production of hydroxyl radicals(·OH).In this study,a novel curative strategy which combines glucose oxidase(GOx)-mediated FeO-based Fenton reaction and multiwalled carbon nanotube(MWNT)-produced mild hyperthermia enhancer is proposed,achieving a mild hyperthermia-enhanced enzyme-mediated tumor cell *** therapy platform,mild hyperthermia-enhanced GOx-mediated CDT,provides an effective treatment for cancer and takes CDT a step further.

纵观历代儒家经典,可以发现其中蕴涵的身体语境极为丰富,这为诠释儒家对“自我”的构建、认知与治理,提供了一个独特的视角。要而言之,儒家构建自我的主体立场,源于“为仁由己”的自觉与自信;基于身体隐喻的自我认知及其拓展,儒家展示了“推己及人”的认知路径;儒家礼治的理据与根本,在于“身国同构”的思维方式;从“修身”到“治政”的交融与贯通,体现了儒家践行自我治理的责任担当和不懈努力。
