| 1 | Optimization of causative factors using logistic regression and artificial neural network models for landslide susceptibility assessment in Ujung Loe Watershed, South Sulawesi Indonesia显示文摘Landslide susceptibility maps(LSMs) play a vital role in assisting land use planning and risk mitigation. This study aims to optimize causative factors using logistic regression(LR) and an artificial neural network(ANN) to produce a LSM. The LSM is produced with 11 causative factors and then optimized using forward-stepwise LR(FSLR), ANN, and their combination(FSLR-ANN) until eight causative factors were found for each method. The ANN method produced superior validation results compared with LR. The ROC values for the training data set ranges between 0.8 and 0.9. On the other hand, validation with the percentage of landslide fall into LSM class high and very high, ANN method was higher(92.59%) than LR(82.12%). FSLR-ANN with nine causative factors gave the best validation results with respect to area under curve(AUC) values, and validation with the percentage of landslide fall into LSM class high and very high. In conclusion, ANN was found to be better than LR when producing LSMs. The best Optimization was combination of FSLR-ANN with nine causative factors and AUC success rate 0.847, predictive rate 0.844 and validation with landslide fall into high and very high class with 91.30%. It is an encouraging preliminary model towards a systematic introduction of FSLR-ANN model for optimization causative factors in landslide susceptibility assessment in the mountainous area of Ujung Loe Watershed. | Andang Suryana SOMA Tetsuya KUBOTA Hideaki MIZUNO | 2019 | Journal of Mountain Science2019，16，2： | 10 |
| 2 | Flexible SERS substrates for hazardous materials detection: recent advances显示文摘This article reviews the most recent advances in the development of flexible substrates used as surface-enhanced Ra-man scattering(SERS)platforms for detecting several hazardous materials(e.g.,explosives,pesticides,drugs,and dyes).Different flexible platforms such as papers/filter papers,fabrics,polymer nanofibers,and cellulose fibers have been investigated over the last few years and their SERS efficacies have been evaluated.We start with an introduction of the importance of hazardous materials trace detection followed by a summary of different SERS methodologies with par-ticular attention on flexible substrates and their advantages over the nanostructures and nanoparticle-based solid/hybrid substrates.The potential of flexible SERS substrates,in conjunction with a simple portable Raman spectrometer,is the power to enable practical/on-field/point of interest applications primarily because of their low-cost and easy sampling. | Moram Sree Satya Bharati Venugopal Rao Soma | 2021 | Opto-Electronic Advances2021，4，11： | 6 |
| 3 | Carbon nanotubes:Evaluation of toxicity at biointerfaces显示文摘Carbon nanotubes (CNTs) are a class of carbon allotropes with interesting properties that make them productive materials for usage in various disciplines of nanotechnology such as in electronics equipments, optics and therapeutics. They exhibit distinguished properties viz., strength, and high electrical and heat conductivity. Their uniqueness can be attributed due to the bonding pattern present between the atoms which are very strong and also exhibit high extreme aspect ratios. CNTs are classified as singlewalled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs) on the basis of number of sidewalls present and the way they are arranged spatially. Application of CNTs to improve the performance of many products, especially in healthcare, has led to an occupational and public exposure to these nanomaterials. Hence, it becomes a major concern to analyze the issues pertaining to the toxicity of CNTs and find the best suitable ways to counter those challenges. This review summarizes the toxicity issues of CNTs in vitro and in vivo in different organ systems (bio interphases) of the body that result in cellular toxicity. | Debashish Mohanta Soma Patnaik Sanchit Sood Nilanjan Das | 2019 | Journal of Pharmaceutical Analysis2019，9，5： | 4 |
| 4 | Low-dose lipopolysaccharide as an immune regulator for homeostasis maintenance in the central nervous system through transformation to neuroprotective microglia显示文摘Microglia,which are tissue-resident macrophages in the brain,play a central role in the brain innate immunity and contribute to the maintenance of brain homeostasis.Lipopolysaccharide is a component of the outer membrane of gram-negative bacteria,and activates immune cells including microglia via Toll-like receptor 4 signaling.Lipopolysaccharide is generally known as an endotoxin,as administration of highdose lipopolysaccharide induces potent systemic inflammation.Also,it has long been recognized that lipopolysaccharide exacerbates neuroinflammation.In contrast,our study revealed that oral administration of lipopolysaccharide ameliorates Alzheimer’s disease pathology and suggested that neuroprotective microglia are involved in this phenomenon.Additionally,other recent studies have accumulated evidence demonstrating that controlled immune training with low-dose lipopolysaccharide prevents neuronal damage by transforming the microglia into a neuroprotective phenotype.Therefore,lipopolysaccharide may not a mere inflammatory inducer,but an immunomodulator that can lead to neuroprotective effects in the brain.In this review,we summarized current studies regarding neuroprotective microglia transformed by immune training with lipopolysaccharide.We state that microglia transformed by lipopolysaccharide preconditioning cannot simply be characterized by their general suppression of proinflammatory mediators and general promotion of anti-inflammatory mediators,but instead must be described by their complex profile comprising various molecules related to inflammatory regulation,phagocytosis,neuroprotection,anti-apoptosis,and antioxidation.In addition,microglial transformation seems to depend on the dose of lipopolysaccharide used during immune training.Immune training of neuroprotective microglia using lowdose lipopolysaccharide,especially through oral lipopolysaccharide administration,may represent an innovative prevention or treatment for neurological diseases;however more vigorous studies are still required to properly modulate these treatments. | Haruka Mizobuchi Gen-Ichiro Soma | 2021 | Neural Regeneration Research2021，16，10： | 3 |
| 5 | CDEX-1 1 kg point-contact germanium detector for low mass dark matter searches显示文摘The CDEX collaboration has been established for direct detection of light dark matter particles, using ultra-low energy threshold point-contact p-type germanium detectors, in China JinPing underground Laboratory(CJPL). The first 1 kg point-contact germanium detector with a sub-keV energy threshold has been tested in a passive shielding system located in CJPL. The outputs from both the point-contact P + electrode and the outside N + electrode make it possible to scan the lower energy range of less than 1 keV and at the same time to detect the higher energy range up to 3 MeV. The outputs from both P + and N + electrode may also provide a more powerful method for signal discrimination for dark matter experiment. Some key parameters, including energy resolution, dead time, decay times of internal X-rays, and system stability, have been tested and measured. The results show that the 1 kg point-contact germanium detector, together with its shielding system and electronics, can run smoothly with good performances. This detector system will be deployed for dark matter search experiments. | 康克军 岳赛 吴呈城 程建平 李元景 白杨 毕勇 常建平 陈楠 陈宁 陈庆豪 陈云华 庄又澄 邓智 杜强 宫辉 郝喜庆 何庆驹 胡鑫洄 黄瀚雄 黄腾锐 江灏 李浩斌 李荐民 李金 李军 李霞 李新颖 李学潜 李玉兰 廖恒毅 林枫凯 林欣德 刘书魁 吕岚春 马豪 毛绍基 覃建强 任杰 任婧 阮锡超 申满斌 Lakhwinder SINGH Manoj Kumar SINGH Arun Kumar SOMA 苏健 唐昌建 曾昭雄 王继敏 王力 王青 王子敬 吴世勇 吴蔚 吴玉成 幸浩洋 徐音 薛涛 杨丽桃 杨松纬 易难 喻纯旭 于昊 余训臻 曾雄辉 曾志 张岚 张蕴华 赵明刚 赵伟 钟苏宁 周祖英 朱敬军 朱维彬 朱学洲 朱忠华 | 2013 | Chinese Physics C2013，37，12： | 3 |
| 6 | First results on ^(76)Ge neutrinoless double beta decay from CDEX-1 experiment显示文摘We report the first results on ^(76)Ge neutrinoless double beta decay from stage one of the China dark-matter experiment(CDEX).A p-type point-contact high-purity germanium detector with a mass of 994 g has been installed to detect neutrinoless double beta decay events, as well as to directly detect dark matter particles. An exposure of 304 kg d has been analyzed over a wide spectral band from 500 keV to 3 MeV. The average event rate obtained was about 0.012 counts per keV per kg per day over the 2.039 MeV energy range. The half-life of ^(76)Ge neutrinoless double beta decay derived based on this result is T^(0ν)1/2>6.4×10^(22) yr(90% C.L.). An upper limit on the effective Majorana-neutrino mass of 5.0 eV has been achieved. | Li Wang Qian Yue KeJun Kang JianPing Cheng YuanJing Li TszKing Henry Wong ShinTed Lin JianPing Chang JingHan Chen QingHao Chen YunHua Chen Zhi Deng Qiang Du Hui Gong Li He QingJu He JinWei Hu HanXiong Huang TengRui Huang LiPing Jia Hao Jiang HauBin Li Hong Li JianMin Li Jin Li Jun Li Xia Li XueQian Li YuLan Li FongKay Lin ShuKui Liu Hao Ma JingLu Ma XingYu Pan Jie Ren XiChao Ruan ManBin Shen Vivek Sharma Lakhwinder Singh Manoj Kumar Singh Manoj Kumar Singh Arun Kumar Soma ChangJian Tang WeiYou Tang ChaoHsiung Tseng JiMin Wang Qing Wang ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue LiTao Yang SongWei Yang Nan Yi ChunXu Yu HaiJun Yu WeiHe Zeng XiongHui Zeng Zhi Zeng Lan Zhang YunHua Zhang MingGang Zhao Wei Zhao JiFang Zhou ZuYing Zhou JingJun Zhu WeiBin Zhu ZhongHua Zhu | 2017 | Science China(Physics,Mechanics & Astronomy)2017，60，7： | 3 |
