In this paper, the application of magnetoelasticity in static tension monitoring for large steel cables is discussed. Magnetoelastic (EM) stress sensors make contact-free tension monitoring possible for hanger cables and post-tensioned cables on suspension and cable-stayed bridges. By quantifying the correlation of magnetic relative permeability with tension and temperature, the EM sensors inspect the load levels in the steel cables. Cable tension monitoring on Qiangjiang (QJ) 4th Bridge demonstrates the reliability of the EM sensors.

The U-Net architecture-based segmentation models attained remarkable performance in numerous medical image segmentation missions like skin lesion segmentation. Nevertheless, the resolution gradually decreases and the loss of spatial information increases with deeper network. The fusion of adjacent layers is not enough to make up for the lost spatial information, thus resulting in errors of segmentation boundary so as to decline the accuracy of segmentation. To tackle the issue, we propose a new deep learning-based segmentation model. In the decoding stage, the feature channels of each decoding unit are concatenated with all the feature channels of the upper coding unit. Which is done in order to ensure the segmentation effect by integrating spatial and semantic information, and promotes the robustness and generalization of our model by combining the atrous spatial pyramid pooling (ASPP) module and channel attention module (CAM). Extensive experiments on ISIC2016 and ISIC2017 common datasets proved that our model implements well and outperforms compared segmentation models for skin lesion segmentation.

High-resolution retinal imaging based on adaptive optics (AO) is important for early diagnosis related to retinal diseases. However, in practical applications, closed-loop AO correction takes a relatively long time, and traditional open-loop correction methods have low accuracy in correction, leading to unsatisfactory imaging results. In this paper, a SH-U-net-based open-loop AO wavefront correction method is presented for a retinal AO imaging system. The SH-U-net builds a mathematical model of the entire AO system through data training, and the Root mean square (RMS) of the distorted wavefront is 0.08λ after correction in the simulation. Furthermore, it has been validated in experiments. The method improves the accuracy of wavefront correction and shortens the correction time.

Hepatitis B virus (HBV) infection is highly prevalent worldwide. The major challenge for current antiviral treatment is the elevated drug resistance that occurs via rapid viral mutagenesis. In this study, we developed AAV vectors to simultaneously deliver two or three shRNAs targeting different HBV-related genes. These vectors showed markedly better antiviral effects than ones that delivered a single shRNA in vitro. A dual shRNA expression vector (AAV-157i/1694i), which simultaneously expressed two shRNAs targeted the S and X genes of HBV, reduced HBsAg, HBeAg and HBV DNA levels by $87{\pm}4$, $80.3{\pm}2.6$ and $86.2{\pm}7%$ respectively, eight days post-transduction. In a mouse model of prophylactic treatment, HBsAg and HBeAg were reduced to undetectable levels and the serum HBV DNA level was reduced by at least 100 fold. These results indicate that AAV-157i/1694i generates potent anti-HBV effects and that the strategy of constructing multi-shRNA expression vectors may lead to enhanced anti-HBV efficacy and overcome the evading mechanism of the virus and thus the development of drug resistance.

This paper traces the historical genealogy of the subjectivity and the silsim (實心, true mind) that appear in Jeong In-Bo's "gukhak" (國學, the national learning) thought and illuminates its characteristics. In the modern East Asian history of thought, the beginning of the emergence of subjectivity and the silsim as the main philosophical topic comes from the Neo-Confucianism of Song Dynasty in China. Cheng Yi is the first thinker to emphasize subjectivity and consciousness. Zhu Xi and Wang Yang-ming inherit the Neo-Confucian thought based on Cheng Yi's principle of subjectivity, but only show difference in methodology. In the Chosun Dynasty, Jeong Je-Doo and his School were one example of the Neo-Confucian spirit of subjectivity and the silsim. Although Jeong In-Bo (鄭寅普) belongs to Jeong Je-Doo's school of Ganghwa in the school curriculum, he has only used it methodologically since he believed that Yangming's learning is more effective in the awareness and practice of the silsim. Especially noteworthy is that the principle of subjectivity led Jeong In-Bo to follow the frame of Zhu Xi's moral theory. Jeong's claim that selfish desire (jasasim 自私心) should be controlled by a conscious mind (silsim) being aware of the right and 'ought to do' corresponds to Zhu Xi's view that the moral mind (dosim 道心) should be selected in the conflict situation between sensual desire (insim 人心) and moral consciousness so that the insim should be supervised by the dosim. Such ethics is a position to emphasize the inner motive and the sense of duty of conduct, and there is no fundamental difference in Zhu Xi and Wang Yang-ming. At least on this point, it is necessary to look at modern and contemporary Korean studies from the perspective of continuity, not discontinuity from Confucian tradition.

Functional food for prevention of chronic diseases is one of this century's key global challenges. Cancer is not only the first or second leading cause of death in China and other countries across the world, but also has diet as one of the most important modifiable risk factors. Major dietary factors now known to promote cancer development are polished grain foods and low intake of fresh vegetables, with general importance for an unhealthy lifestyle and obesity. The strategies of cancer prevention in human being are increased consumption of functional foods like whole grains (brown rice, barley, and buckwheat) and by-products, as well some vegetables (bitter melon, garlic, onions, broccoli, and cabbage) and mushrooms (boletes and Tricholoma matsutake). In addition some beverages (green tea and coffee) may be protective. Southwest China (especially Yunnan Province) is a geographical area where functional crop production is closely related to the origins of human evolution with implications for anticancer influence.

Zhu Dan Xi's name is ZhenHeng(震亨) and was also called by the title of YanXiu(彦修). Early in his life, he started to study JuZiYe(擧子業), and went on to study DaoDeXingMingXue(道德性命學) under the teachings of XueQian(許謙), who as one of fourth generation disciple of ZhuZi(朱子) was teaching in BaHuaShan(八華山). His well-known literary works are ${\ulcorner}$JuFangFaHui(局方發揮)${\lrcorner}$, ${\ulcorner}$GeZhiYuLun${\lrcorner}$, ${\ulcorner}$ShangHanBianYi(傷寒辨疑)${\lrcorner}$, ${\ulcorner}$BenCaoYanYiBuYi(本草衍義補遺)${\lrcorner}$, ${\ulcorner}$WaiKeJingYaoXinLun(外科精要新論)${\lrcorner}$. Zhu Dan Xi learnt the studies of Liu(劉), Zhang(張), Li(李) from LouZhiTi(羅知悌) and adopted the advantages and abolished disadvantages from it. The southern district being low and damp, which also leads to a geographical condition with a lot of ShiReXiangHuo(濕熱相火) disease and with the social background of people exhausting their QingYu(情欲) and damaging QLXie(氣血), he came out with the theory of 'YangYouYuYinBuZu(陽有餘陰不足)', 'XiangHuo(相火)' and became a well renowned expert in diagnosis and treatment of QiXieTanYuHuo(氣血痰鬱火). As a result, the writer has performed a research based on Liu's works and related theories, GuWuZhiZhi theory, the understanding of TaiJiZhiLi(太極之理), the inner meaning of YinYang and YouYuBuZu(redundancy-and-deficit), YinYangDongJingGuan, physiology and pathology, the medical reason of lust damaging QingYuYangYin and YangSheng(養生)(preservation of health), which are the main medical theory of ZhuDanXi, comments of later generations and is reporting the outcome.

Radiation therapy is an important treatment for head and neck squamous cell carcinoma (HNSCC). However, how to promote radiation sensitivity in HNSCC remains a challenge. This study aimed to investigate the radiosensitizing effects of fenofibrate on HNSCC and explore the underlying mechanisms. HNSCC cell lines CNE-2 and KB were subjected to ionizing radiation (IR), in the presence or absence of fenofibrate treatment. Cell growth and survival, apoptosis and cell cycle were evaluated. In addition, CNE-2 cells were xenografted into nude mice and subjected to IR and/or fenofibrate treatment. The expression of cyclinB and CDK1 was detected by Western blotting. Our results showed that fenofibrate efficiently radiosensitized HNSCC cells and xenografts in mice, and induced apoptosis and G2/M arrest via reducing the activity of the CDK1/cyclinB1 kinase complex. These data suggest that fenofibrate could be a promising radiosensitizer for HNSCC radiotherapy.
