| 1 | A Hybrid Aspect Based Latent Factor Model for Recommendation显示文摘Recommender system has been recognized as a superior way for solving personal information overload problem.More and more aspect-based models are leveraging user ratings and extracting information from review texts to support recommendation.Aspect-based latent factor model predicts user ratings relying on latent aspect inferred from user reviews.It usually constructs only a single global model for all users,which may be not sufficient to capture the diversity of users'preferences and leave some items or users be badly modeled.We propose a Hybrid aspect-based latent factor model(HALFM),which jointly optimizes the Global aspect-based latent factor model(GALFM)and the Local Aspect-based Latent Factor Models(LALFM),their user-specific combination,and the assignment of users to the LALFMs.HALFM makes prediction by combining user-specific of GALFM and many LALFMs.Experimental results demonstrate that the proposed HALFM outperforms most of aspectbased recommendation techniques in rating prediction. | YUAN Hanning CHEN Zhengyu YANG Jingting WANG Shuliang GENG Jing KE Chuwen | 2020 | Chinese Journal of Electronics2020，29，3： | 1 |
| 2 | Self-shrinking supramolecular nanoparticles syndicate energy suppression and NIR-II mild photothermal amplification of mitochondrial oxidative stress for breast cancer therapy显示文摘Photothermal therapy(PTT)may lead to healthy tissue damage,tumor metastasis,and recurrence,which makes mild photothermal therapy(mild PTT)stand out.However,overcoming heat resistance,insufficient therapeutic effect,and poor photothermal conversion efficiency has become new challenge.Herein,we report a dynamic supramolecular nanocarrier formed from amide-sericin and aldehyde-polyhydroxy glucan(denoted as SDA),the loose cavity of which can be filled by using the pharmaceutical combination of lonidamine(LND)and NIR-II photothermal agent of IR-1061,producing SDLI with a tighter inner hole,smaller and uniform particle size and excellent stability due to multiple pulling forces.Moreover,the intricate internal network structure prevents the hydrophobic IR-1061 from forming aggregates in the small cavity,and the photothermal conversion efficiency(PCE)can reach 48.9%.At the acidic tumor microenvironment of pH 6.5,the controlled release of LND can solve the problem of heat resistance of NIR-II mild PTT and significantly improve the therapeutic effect of NIR-II mild PTT.Meanwhile,SDLI also shows a reasonable tumor inhibition rate,so the synergistic strategy of inhibiting tumor energy metabolism and NIR-II mild PTT to magnify mitochondrial oxidative stress,continuous cell stress state-induced immunogenic cell death to promote the induction of tumor apoptosis is proposed to achieve more effective cancer treatment. | Hongmei Liu Jiming Xu Mengjie Ye Hengbo Zhang Linlin Han Jingting Wang Peng Xue Yuejun Kang Zhigang Xu | 2024 | Nano Research2024，17，5： | 0 |
| 3 | A study of the temporal and spatial variations in the suitability of the environment in Chinese cities for tourism and in strategies for optimizing the environment显示文摘With the aim of guaranteeing the interests and health of tourists,this study comprehensively evaluates the suitability of the environment in different cities in China for tourism by considering the impacts of climate,vegetation and environmental factors on health.The Universal Thermal Climate Index(UTCI),total precipitation(PREC),Vegetation Leaf Area Index(LAI),concentration of particulate matter with a diameter of less than 2.5μm(PM2.5),and the downward UV radiation at the surface(UVB)are used as indices.In addition,the Delphi–AHP–TOPSIS algorithm is introduced and is used for the comprehensive evaluation of the environmental suitability of 684 cities in China for tourism in 2019.It is found that Chinese cities vary greatly in terms of the suitability of their environments for tourism.Among the factors that affect the environmental suitability,the LAI is important,with an increase in the LAI generally being advantageous.In contrast,an increase in the PM2.5 concentration is a key factor that limits the environmental suitability of an area.Thus,urban landscaping and control of the atmospheric quality are essential and effective ways of improving the suitability of the environment of cities in China for tourists. | Ying Li Shuhui Zhang Jingting Han Yi Zhao Quan Han Liyun Wu Xin Wang Ziyi Qiu Tongqian Zou Cheng Fan | 2022 | International Journal of Digital Earth2022，15，1： | 0 |
