Through statistical process controlling the quality characteristic of bearings’ diameters and multi-vary analysis is applied to find the key variation factors which have an influence on the quality characteristic of the bearings, the quality level of the bearings of this company is improved.

Novel Understanding of Electron States Architecture and Its Dimensionality in Semiconductors  [PDF]
Xiaomin Ren
Optics and Photonics Journal (OPJ) , 2013, DOI: 10.4236/opj.2013.32B075

Some important insights into the electron-states-architecture (ESA) and its dimensionality (from 3 to 0) in a semiconductor (or generally crystalline) material are obtained. The self-consistency of the set of density of states (DOS) expressions with different dimensionalities is remediated through the clarification and rearrangement of the wave-function boundary conditions for working out the eigenvalues in the wave vector space. The actually too roughly observed and theoretically unpredicted critical points for the dimensionality transitions referring to the integer ones are revealed upon an unusual assumption of the intrinsic energy-level dispersion (ELD). The ELD based quantitative physical model had been established on an immediate instinct at the very beginning and has been properly modified afterwards. The uncertainty regarding the relationship between the de Broglie wavelength of electrons and the dimensionality transitions, seeming somewhat mysterious before, is consequentially eliminated. The effect of the material dimensions on the ELD width is also predicted and has been included in the model. The continuous evolution of the ESA dimensionality is convincingly and comprehensively interpreted and thus the area of the fractional ESA dimensionalities is opened. Another new assumption of the spatial extension shrinkage (SES) closely related to the ELD has also been made and thus the understanding of the behavior of an electron or, in a general sense, a particle has become more comprehensive. This work would manifest itself a new basis for further development of nanoheterostructures (or low dimensional heterostructures including the quantum wells, quantum wires, quantum dots and especially the hetero-dimensional structures).

When “Parents Privilege Competition” Will Not Be an Exclusive Resource?  [PDF]
Xiaomin Guo
Open Journal of Social Sciences (JSS) , 2018, DOI: 10.4236/jss.2018.64004
We describe a common social phenomenon in this article. It is that when children grow up, in addition to their talents and efforts in comparison with their peers, the parental background between children is also an important stake in their competition. Parents’ social status and superior power will result in more social resources and opportunities for children. We call this phenomenon “parents privilege competition”. The root cause of this phenomenon is the serious hardening of the stratum and the poor social mobility in vertical society, which makes it difficult for children to have an equal competitive environment. After analyzing the phenomenon, this article discusses the causes of this phenomenon and the solutions.
Antioxidant Properties of Cap and Stipe from Coprinus comatus

Molecules , 2010, DOI: 10.3390/molecules15031473
Abstract: Coprinus comatus, also called chicken drumstick mushroom, is currently commercially available in China. Hot water and ethanolic extracts were prepared from cap and stipe of C. comatus fruit bodies and their antioxidant properties were studied. Ethanolic extract from stipe showed high antioxidant activity (80.6%) at 1 mg/mL. Reducing power of hot water extracts from cap was 1.653 at 10 mg/mL. Extracts from cap showed better scavenging ability on DPPH (57.9% at 1 mg/mL) than stipe ones. Ethanolic extracts were more effective in scavenging ability on hydroxyl radicals (57.4–61.3% at 5 mg/mL) than hot water extracts. Ethanolic extracts showed moderate scavenging ability on superoxide radicals (46.3–47.0% at 20 mg/mL). Naturally occurring antioxidant components including total phenols (3.60–20.00 mg/g), tocopherols (0.58–11.93 mg/g), flavonoids (0.19–3.52 mg/g) and polysaccharides (58.52–547.86 mg/g) were found in the extracts. Overall, extracts from cap were more effective for the antioxidant properties assayed.
Development of a pediment on western slopes of Liupan Mountain related to the Neotectonic Uplift
Dong Yang,Xiaomin Fang,Yougui Song,Lianqing Lu,Jijun Li
Chinese Science Bulletin , 2001, DOI: 10.1007/BF03187229
Abstract: The late Cenozoic uplift of Qinghai-Xizang Plateau plays an important role in adjacent geomorphic evolution and depositional environments. Liupan Mountain, located at the northeast margin of Qinghai-Xizang Plateau, has different landforms on the east and west sides. Recently, a pediment, which lies above the highest terrace of the Yellow River at the northeast edge of Longzhong Basin, has been described. The paleomagnetic measurements indicate that the pediment had developed at least 1.8 MaBP and its age is in accordance with that of the peneplains near Lanzhou and Linxia, in the southwest of Longzhong Basin. The results suggest that the Longzhong Basin lying to the west of Liupan Mountain had been subject to erosion and developed an extensive pediment; this pediment is named the Gansu Period Peneplain. It also indicates that Qinghai-Xizang Plateau and Liupan Mountain were uplifted strongly at that time, which caused not only the end of pediplanation but also Yellow River appearance and loess accumulation.

AFM and LSCM Studies of Choriocarcinoma Cell Line JAR Infected by Hepatitis B Virus
Lu Gan,Ming Wei,Caiping Ke,Zhao Zhang,Xiaomin Xiao
Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.2923.2925
Abstract: Choriocarcinoma cell line JAR was used as a model to study trophoblast. In this study, the morphological changes and three-dimensional reconstruction of JAR infected by Hepatitis B Virus (HBV) were detected with the use of Atomic Force Microscope (AFM) and Laser Scanning Confocal Microscope (LSCM). It was clearly shown that the HBsAg located in the cytoplasm or at the edge of the nucleus of JAR cells infected by HBV, the membrane of JAR cells infected by HBV were depressed, boundaries of cytoplasm and nucleus were unclear. The membrane of JAR were covered by particles and the histogram of particles in the negative group distributed from 400-800 nm in diameter, most of paticles were 800 nm while the particles of JAR cells infected by HBV ranged from 200-600 nm, most of paticles were 400 nm. HBV serum can infect JAR cells in vitro, the changes of the morphology of JAR cells infected by HBV were related to the damage of the particles on the membrane of JAR cells. AFM can be useful for studying cell pathology.
Construction and Validation of Self-Management Scale for Undergraduate Students  [PDF]
Gang Xue, Xiaomin Sun
Creative Education (CE) , 2011, DOI: 10.4236/ce.2011.22020
Abstract: This study developed a scale to assess undergraduate students’ self-management ability in daily life. Forty items about self-management on time, goal, emotions and personal relationships were generated for the draft scale. Content review panel deleted seven items. In Study 1, 522 Chinese undergraduate students took the test. Exploratory factor analysis and item analysis on the first half 261 cases deleted 6 items. Confirmatory factor analysis further revised the model and resulted in a two-factor Self-Management Scale, consisting of 21 items. Cross-validation on the second half 261 cases also verified the scale’s structural validity. In Study 2, responses from 374 undergraduate students were used to examine the reliability and criterion-related validity of the scale. The internal consistency reliability of the scale was 0.86. Relationship management showed good criterion-related validity, while the validity of performance management needs further examination.
