A New Interpretation of Family Education under Sociological Perspective  [PDF]
Yanjin Liu, Xuntao Yue
Open Journal of Social Sciences (JSS) , 2018, DOI: 10.4236/jss.2018.65012
Abstract: In Education, family education is a vague concept, for its lack of comprehensive account for what it is and how it is doing. Therefore the study of it from the perspective of educational sociology enriches the connotation of family education, as well as its denotation. The new interpretation of family education will strive to present a more complete picture of family education, and explain the rationality and richness of family education, while avoiding the limitations and misunderstandings in the understanding.
The Locus of Plane Quartics with A Hyperflex

Mathematics , 2015,
Abstract: In 1989 Cukierman computed the homology class in in $\overline{\mathcal{M}_3}$ of the locus of plane quartics with a hyperflex line. In this paper we provide an alternative direct approach to this problem by determining an explicit Siegel modular form whose zero locus in $\overline{\mathcal{M}_3}$ is the hyperflex locus. The knowledge of such an explicit modular form also allows us to describe explicitly the boundary of the hyperflex locus within the Deligne-Mumford compactification $\overline{\mathcal{M}_3}$. As an example we show that the locus of banana curves (two irreducible components intersecting at two nodes) is contained in the hyperflex locus.

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0073208
Abstract: Objectives To examine possible changes in cortical thickness and their relationship to retinal nerve fiber layer (RNFL) thickness in patients with primary open-angle glaucoma (POAG). Materials and Methods Thirty-six patients with POAG and 40 matched healthy controls were enrolled in this study. All subjects underwent a comprehensive ophthalmologic examination and a high resolution structural magnetic resonance scan. Cortical thickness analysis was used to assess the changes between patients and controls. Correlations between the thickness of the visual cortex and RNFL thickness were also analyzed. Finally, the relationship between the severity of changes in the visual cortex and RNFL thickness was evaluated by comparing patients with mild and severe groups. Results POAG patients showed significant bilateral cortical thinning in the anterior half of the visual cortex around the calcarine sulci (left BA 17 and BA 18, right BA17) and in some smaller regions located in the left middle temporal gyrus (BA37) and fusiform gyrus (BA19). The thickness of the visual cortex correlated positively with RNFL thickness (left, r = 0.44, p = 0.01; right, r = 0.38, p = 0.03). Significant differences between mild and severe groups were observed with regard to both RNFL thickness and the thickness of bilateral visual cortex (p < 0.05). Conclusion Our findings indicate that cortical thickness analysis may be sufficiently sensitive to detect cortical alterations in POAG and that the measurement has great potential for clinical application.

PLOS ONE , 2014, DOI: 10.1371/journal.pone.0087880
Abstract: Objectives To investigate the amplitude of low-frequency fluctuations (ALFF) alteration of whole brain in patients with subcortical ischemic vascular dementia (SIVD). Materials and Methods Thirty patients with SIVD and 35 control subjects were included in this study. All of them underwent structural MRI and rs-fMRI scan. The structural data were processed using the voxel-based morphometry 8 toolbox (VBM8). The rs-fMRI data were processed using Statistical Parametric Mapping (SPM8) and Data Processing Assistant for Resting-State fMRI (DPARSF) software. Within-group analysis was performed with a one-sample Student's t-test to identify brain regions with ALFF value larger than the mean. Intergroup analysis was performed with a two-sample Student's t-test to identify ALFF differences of whole brain between SIVD and control subjects. Partial correlations between ALFF values and Montreal Cognitive Assessment (MoCA) and Mini-Mental State Examination (MMSE) scores were analyzed in the SIVD group across the parameters of age, gender, years of education, and GM volume. Results Within-group analysis showed that the bilateral anterior cingulate cortex (ACC), posterior cingulate cortex, medial prefrontal cortex (MPFC), inferior parietal lobe (IPL), occipital lobe, and adjacent precuneus had significantly higher standardized ALFF values than the global mean ALFF value in both groups. Compared to the controls, patients with SIVD presented lower ALFF values in the bilateral precuneus and higher ALFF values in the bilateral ACC, left insula and hippocampus. Including GM volume as an extra covariate, the ALFF inter-group difference exhibited highly similar spatial patterns to those without GM volume correcting. Close negative correlations were found between the ALFF values of left insula and the MoCA and MMSE scores of SIVD patients. Conclusion SIVD is associated with a unique spontaneous aberrant activity of rs-fMRI signals, and measurement of ALFF in the precuneus, ACC, insula, and hippocampus may aid in the detection of SIVD.
Comparison of Medial Temporal Measures between Binswanger's Disease and Alzheimer's Disease
Xuntao Yin, Chen Liu, Li Gui, Lu Zhao, Jiuquan Zhang, Luqing Wei, Bing Xie, Daiquan Zhou, Chuanming Li, Jian Wang
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0086423
Abstract: Binswanger's disease (BD) is a common cause of vascular dementia in elderly patients; however, few studies have investigated the medial temporal lobe (MTL) atrophy in BD, and the differences in the atrophic patterns between BD and Alzheimer's disease (AD) remain largely unknown. Such knowledge is essential for understanding the pathologic basis of dementia. In this study, we collected structural magnetic resonance imaging (MRI) data from 16 normal controls, 14 patients with AD and 14 patients with BD. The volumes of the hippocampus and amygdala, and morphologic parameters (volume, surface area, cortical thickness and mean curvature) of the entorhinal cortex (ERC) and perirhinal cortex (PRC) were calculated using an automated approach. Volume reduction of the hippocampus, amygdala and ERC, and disturbance of the PRC curvature was found in both AD and BD patients compared with the controls (p<0.05, uncorrected). There were no significant differences among all the structural measures between the AD and BD patients. Finally, partial correlation analyses revealed that cognitive decline could be attributed to ERC thinning in AD and volume reduction of PRC in BD. We conclude that AD and BD exhibit similar atrophy patterns in the medial temporal cortices and deep gray matter but have distinct pathologic bases for cognitive impairments. Although atrophy of the MTL structures is a sensitive biomarker for AD, it is not superior for discrimination between AD and BD.
Fiber Pathways of Attention Subnetworks Revealed with Tract-Based Spatial Statistics (TBSS) and Probabilistic Tractography
Haitao Ge, Xuntao Yin, Junhai Xu, Yuchun Tang, Yan Han, Wenjian Xu, Zengchang Pang, Haiwei Meng, Shuwei Liu
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0078831
Abstract: It has been widely accepted that attention can be divided into three subnetworks - alerting, orienting and executive control (EC), and the subnetworks of attention are linked to distinct brain regions. However, the association between specific white matter fibers and the subnetworks of attention is not clear enough. Using diffusion tensor imaging (DTI), the white matter connectivity related to the performance of attention was assessed by attention network test (ANT) in 85 healthy adolescents. Tract-based spatial statistics (TBSS) and probabilistic diffusion tractography analysis demonstrated that cerebellothalamic tract was involved in alerting, while orienting depended upon the superior longitudinal fasciculus (SLF). In addition, EC was under the control of anterior corona radiata (ACR). Our findings suggest that different fiber pathways are involved in the three distinct subnetworks of attention. The current study will yield more precise information about the structural substrates of attention function and may aid the efforts to understand the neurophysiology of several attention disorders.
Mixed Training: A New Perspective of Post-Service Training for Teachers  [PDF]
Xuntao Yue, Ziling Liu
Open Journal of Social Sciences (JSS) , 2019, DOI: 10.4236/jss.2019.76010
Abstract: The effectiveness of teacher training has been criticized. To change this situation, it is advisable to use mixed training instead of single training mode. Mixed training combines the advantages of various training modes, expands the learning space of teachers, constructs a system of mutual support among teachers, forms a three-dimensional model of teacher training and normalization of teacher training, and effectively promotes the professional development of teachers.

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0050590
Abstract: Both neuropsychological and functional neuroimaging studies have identified that the posterior parietal lobe (PPL) is critical for the attention function. However, the unique role of distinct parietal cortical subregions and their underlying white matter (WM) remains in question. In this study, we collected both magnetic resonance imaging and diffusion tensor imaging (DTI) data in normal participants, and evaluated their attention performance using attention network test (ANT), which could isolate three different attention components: alerting, orienting and executive control. Cortical thickness, surface area and DTI parameters were extracted from predefined PPL subregions and correlated with behavioural performance. Tract-based spatial statistics (TBSS) was used for the voxel-wise statistical analysis. Results indicated structure-behaviour relationships on multiple levels. First, a link between the cortical thickness and WM integrity of the right inferior parietal regions and orienting performance was observed. Specifically, probabilistic tractography demonstrated that the integrity of WM connectivity between the bilateral inferior parietal lobules mediated the orienting performance. Second, the scores of executive control were significantly associated with the WM diffusion metrics of the right supramarginal gyrus. Finally, TBSS analysis revealed that alerting performance was significant correlated with the fractional anisotropy of local WM connecting the right thalamus and supplementary motor area. We conclude that distinct areas and features within PPL are associated with different components of attention. These findings could yield a more complete understanding of the nature of the PPL contribution to visuospatial attention.

Xuemeng Yin, Xinmin Yin
Open Journal of Stomatology (OJST) , 2014, DOI: 10.4236/ojst.2014.41001
Abstract:

Objective: To evaluate the effect of wireless biofeedback therapy on bruxism. Methods: Fifteen bruxiers participated to be treated by this therapy. The abnormal movements of teeth during sleep were monitored by a maxillary splint with an electric resistance strain gauge. Meanwhile, the receiver device recorded these details and analyzed the data, including the value of the biting force, occurring time and duration. If the value of biting force or duration exceeds the threshold, a vibrating device like a watch style will alert the patient to relax the masticatory muscles and nervous system to stop the abnormal grinding or clenching. Data were recorded during 8 hours’ sleep and analyzed after the 12 weeks’ treatment and 24 weeks’ treatment. Results: The average episodes of bruxism have declined from (10.60 ± 1.23) to (6.60 ± 0.75) after 12 weeks’ treatment (p < 0.05), and the average duration of bruxism events was reduced from (13.2 ± 0.74) s to (6.50 ± 0.40) s (p < 0.05). The average episodes of bruxism have declined to (3.80 ± 0.64) after 24 weeks’ treatment, and the average duration of bruxism events was reduced to (3.37 ± 0.34) s (p < 0.05). Conclusions: The results suggest that biofeedback therapy can be effective for bruxism treatment.

Xuntao Xu,Fengchun Tian,Simon X. Yang,Qi Li,Jia Yan,Jianwei Machacek
Sensors , 2008, DOI: 10.3390/s8116885
Abstract: In this paper, a solid trap/thermal desorption-based odorant gas condensation system has been designed and implemented for measuring low concentration odorant gas. The technique was successfully applied to a medical electronic nose system. The developed system consists of a flow control unit, a temperature control unit and a sorbent tube. The theoretical analysis and experimental results indicate that gas condensation, together with the medical electronic nose system can significantly reduce the detection limit of the nose system and increase the system’s ability to distinguish low concentration gas samples. In addition, the integrated system can remove the influence of background components and fluctuation of operational environment. Even with strong disturbances such as water vapour and ethanol gas, the developed system can classify the test samples accurately.
