| 1 | Visual Fixation Assessment in Patients with Disorders of Consciousness Based on Brain-Computer Interface显示文摘Visual fixation is an item in the visual function subscale of the Coma Recovery Scale-Revised(CRS-R).Sometimes clinicians using the behavioral scales find it difficult to detect because of the motor impairment in patients with disorders of consciousness(DOCs). Braincomputer interface(BCI) can be used to improve clinical assessment because it directly detects the brain response to an external stimulus in the absence of behavioral expression. In this study, we designed a BCI system to assist the visual fixation assessment of DOC patients. The results from 15 patients indicated that three showed visual fixation in both CRS-R and BCI assessments and one did not show such behavior in the CRS-R assessment but achieved significant online accuracy in the BCI assessment. The results revealed that electroencephalography-based BCI can detect the brain response for visual fixation. Therefore,the proposed BCI may provide a promising method for assisting behavioral assessment using the CRS-R. | Jun Xiao Jiahui Pan Yanbin He Qiuyou Xie Tianyou Yu Haiyun Huang Wei Lv Jiechun Zhang Ronghao Yu Yuanqing Li | 2018 | Neuroscience Bulletin2018，34，4： | 9 |
| 2 | Site response in the Qionghai Basin in the Wenchuan earthquake显示文摘Amplification effects of soil site response can significantly impact ground motions, and must be considered in the seismic fortification of buildings/structures to prevent or mitigate this potential seismic hazard. Utilizing acceleration time histories from the main shock of the Wenchuan earthquake recorded at four stations (i.e., one on bedrock and three on soil) in the Qionghai Basin, the site responses from three soil sites are studied by using the traditional spectral ratio method. The bedrock site is selected as a reference site. This study found that peak ground accelerations (PGAs) on the soil sites are much larger than on bedrock, with EW, NS and UD components of 3.96-6.58, 6.27-10.98, and 3.17-6.66 times those of the bedrock site, respectively. The amplification effects of the soil sites on ground motions in the frequency range of 0.1 Hz to 10 Hz are significant, depending on the thickness of the soil layer and the frequency content of the site. A significant amplification occurs with high frequency components of ground motion at shallow soil sites, and low and high frequency components of ground motion at intermediate soil sites. | Wang Haiyun Xie Lili Wang Suyang Ye Peng | 2013 | Earthquake Engineering and Engineering Vibration2013，12，2： | 3 |

| 5 | Separation of galena and chalcopyrite using the difference in their surface acid corrosion characteristics显示文摘Galena(PbS)and chalcopyrite(CuFeS_(2))are sulfide minerals that exhibit good floatability characteristics.Thus,efficiently separating them via common flotation is challenging.Herein,a new method of surface sulfuric acid corrosion in conjunction with flotation separation was proposed,and the efficient separation of galena and chalcopyrite was successfully realized.Contact angle test results showed a substantial decrease in surface contact angle and a selective inhibition of surface floatability for corroded galena.Meanwhile,the contact angle and floatability of corroded chalcopyrite remained almost unaffected.Scanning electron microscope results confirmed that sulfuric acid corrosion led to the formation of a dense oxide layer on the galena surface,whereas the chalcopyrite surface remained unaltered.X-ray photoelectron spectroscopy results showed that the chemical state of S^(2-)on the surface of corroded galena was oxidized to SO_(4)^(2-).A layer of hydrophilic PbSO4was formed on the surface,leading to a sharp decrease in galena floatability.Meanwhile,new hydrophobic CuS_(2),CuS,and Cu_(1-x)Fe_(1-y)S_(2-z)species exhibiting good floatability were generated on the chalcopyrite surface.Finally,theoretical analysis results were further verified by corrosion–flotation separation experiments.The galena–chalcopyrite mixture was completely separated via flotation separation under appropriate corrosion acidity,corrosion temperature,and corrosion time.A novel approach has been outlined in this study,providing potential applications in the efficient separation of refractory copper–lead sulfide ore. | Haiyun Xie Jialing Chen Pei Zhang Likun Gao Dianwen Liu Luzheng Chen | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，11： | 0 |
| 6 | Experimental study on the uptake and effects of arsenic originated from poultry litter on the growth of Brassica napus in greenhouse pot cultivation and health risk assessment显示文摘Organoarsenics are widely used as growth promoters in poultry industry,resulting in arsenic(As)accumulation in poultry litter.A greenhouse pot study was implemented to investigate the fate of arsenic originated from poultry litter and their effects on the growth of Brassica napus(oilseed rape),and assess their potential health risks.Five poultry litter application rates(0,5%,10%,20%and 40%)were used,dividing into two groups:one for soil incubation(SI)and the other for plant cultivation(PC).Experimental results indicated that the total arsenic for composted poultry litter was(10.94±0.23)mg/kg,As(V)and As(III)decreased while methylated arsenic increased after 21 d in SI and PC treatments.Seed germination rates were negatively correlated with monomethylarsenic acid(MMA,R2=0.63,p<0.05).The length and biomass of roots and shoots were significantly inhibited by poultry litter,but plant length of 5%treatments was slightly stimulated.Within an average weekly intake of 0.5 kg Brassica napuss,the risk quotient(RQ)values induced from roots nearly all surpassed the acceptable limit(1),were two orders magnitude higher than shoots.According to the potential risk to order,child exhibited the highest risk,adolescent ranked secondly,and adult exhibited the lowest risk.Hence,people should better avoid intake Brassica napus roots to reduce arsenic potential risk. | Xie Haiyun Han Deming Cheng Jinping Wang Liang Zhou Pei Wang Wenhua | 2016 | International Journal of Agricultural and Biological Engineering2016，9，3： | 0 |
