A Representative of the New Female Image—Analyzing Hester Prynne’s Feminist Consciousness in The Scarlet Letter
Yamin Wang
Journal of Language Teaching and Research , 2010, DOI: 10.4304/jltr.1.6.893-897
Abstract: The Scarlet Letter is generally considered to be Nathaniel Hawthorne’s best work and one of the indubitable masterpieces of American literature. The heroine of the novel—Hester Prynne, though on a binary position as a woman in Puritan society, defies power and puts up a tenacious fight against the colonial rule combined by church and state. From her rebellious actions, we can see Hester’s feminist consciousness. With this noble character, she becomes totally different from the traditional women who are always obedient to the unfair rules enacted by men. It can be sensed that a new female image is born. This paper tries to analyze Hester’s feminist consciousness at the respect of her rebellious spirit, self-reliance and strong mind, in this way to evaluate Hester Prynne as a representative of the new female image. Through this kind of analysis, we can better dig in the figure of Hester, and regarding her as a new woman also has a positive social meaning in encouraging women today to strive after the lofty ideal— an equal status between men and women.

Yamin Wang, Xiaozhou Yin, Yong Liu
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.36067
Abstract: In this paper, by utilizing the fractional calculus theory and computer simulations, dynamics of the fractional order system is studied. Further, we have extended the nonlinear feedback control in ODE systems to fractional order systems, in order to eliminate the chaotic behavior. The results are proved analytically by stability condition for fractional order system. Moreover numerical simulations are shown to verify the effectiveness of the proposed control scheme.

Jacobus Leo, Hao Tan, Yinzhe Ma, Shreyas M. Parab, Yamin Huang, Dandan Wang, Lei Zhu, Jeffrey Lam, Zhihong Mai
Journal of Applied Mathematics and Physics (JAMP) , 2017, DOI: 10.4236/jamp.2017.59139
“Industry 4.0” has become the future direction of manufacturing industry. To prepare for this upgrade, it is important to study the automation of semiconductor failure analysis. In this paper, the sample polishing activity was studied for upgrading to a smart polishing process. Two major issues were identified in implementing the smart polishing process: the optimization of current polishing recipes and the capability of making decisions based on live feedback. With the help of Solver add-in, the current polishing recipes were optimized. To make decisions based on live images captured during polishing, strategies were explored based on finger polishing process study. Our investigation showed that a grey scale line profile analysis on images can be used to build the vision capability of our smart polishing system, on which a decision- making capability can be developed.
Application of Improved Analysis of Variance to Ionospheric TEC Short-Term Forecast  [PDF]
Yan Gong, Yamin Dang
Positioning (POS) , 2011, DOI: 10.4236/pos.2011.21005
Abstract: An improved superposition analysis of periodical wave variance is used for short-term forecast of the ionosphere TEC in this study. Using the ionospheric TEC data provided by IGS as the real value, the forecasting precision of this me-thod at different locations in China with 40 days data is evaluated. The result shows that the improved method has a better forecasting precision which could reach 1.1 TECU. But the forecasting precision still relates to geographical position, it is proportional to longitude and inversely proportional to latitude. Compared with the current-used methods, the improved method has many advantages as higher precision, using fewer parameters and easier to calculate. So, it applied to ionosphere short-term prediction in China very well.
Protoplasmic Astrocytes Enhance the Ability of Neural Stem Cells to Differentiate into Neurons In Vitro

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0038243
Abstract: Protoplasmic astrocytes have been reported to exhibit neuroprotective effects on neurons, but there has been no direct evidence for a functional relationship between protoplasmic astrocytes and neural stem cells (NSCs). In this study, we examined neuronal differentiation of NSCs induced by protoplasmic astrocytes in a co-culture model. Protoplasmic astrocytes were isolated from new-born and NSCs from the E13-15 cortex of rats respectively. The differentiated cells labeled with neuron-specific marker β-tubulin III, were dramatically increased at 7 days in the co-culture condition. Blocking the effects of brain-derived neurotrophic factor (BDNF) with an anti-BDNF antibody reduced the number of neurons differentiated from NSCs when co-cultured with protoplasmic astrocytes. In fact, the content of BDNF in the supernatant obtained from protoplasmic astrocytes and NSCs co-culture media was significantly greater than that from control media conditions. These results indicate that protoplasmic astrocytes promote neuronal differentiation of NSCs, which is driven, at least in part, by BDNF.

Saudi Medical Journal , 2012,
Abstract: Objective: To conduct a meta-analysis of observational studies to explore the relationships between cholecystectomy and the risk of esophageal and gastric cancer (GC). Methods: The study design was retrospective, and carried out in the First People’s Hospital of Nantong, Jiangsu, China from January 2012 to April 2012. Studies were identified by a literature search of MEDLINE and EMBASE through March 31, 2012, and by manually searching the reference lists of pertinent articles. The summary relative risks (SRRs) with their 95% confidence intervals (CIs) were calculated with a random-effects model. Results: A total of 12 estimates from 6 independent studies (including 1,622 esophageal cancer [EC] cases and 2,314 GC cases) were included in this meta-analysis. We found that cholecystectomy was not associated with risk of EC and GC (EC: SRRs - 1.03; 95% CI: 0.94-1.13; heterogeneity: p=0.496; I2=0; n=4 studies; [GC: SRRs - 1.03; 95% CI: 0.93-1.13; heterogeneity: p=0.652; I2=0; n=5 studies]). Sub-grouped analyses revealed that these null associations were independent of geographic location and study design. Based on 2 studies, we found patients undergoing cholecystectomy at least 10 years before had an elevated risk of esophageal adenocarcinoma (EAC). Conclusion: The results of this meta-analysis suggest that cholecystectomy does not increase the risk of esophageal squamous cell carcinoma and GC development, but may increase EAC risk. More epidemiological research of a prospective design is needed to further clarify these associations in the future.
Effects of Acupuncture at GV20 and ST36 on the Expression of Matrix Metalloproteinase 2, Aquaporin 4, and Aquaporin 9 in Rats Subjected to Cerebral Ischemia/Reperfusion Injury

PLOS ONE , 2014, DOI: 10.1371/journal.pone.0097488
Abstract: Background/Purpose Ischemic stroke is characterized by high morbidity and mortality worldwide. Matrix metalloproteinase 2 (MMP2), aquaporin (AQP) 4, and AQP9 are linked to permeabilization of the blood-brain barrier (BBB) in cerebral ischemia/reperfusion injury (CIRI). BBB disruption, tissue inflammation, and MMP/AQP upregulation jointly provoke brain edema/swelling after CIRI, while acupuncture and electroacupuncture can alleviate CIRI symptoms. This study evaluated the hypothesis that acupuncture and electroacupuncture can similarly exert neuroprotective actions in a rat model of middle cerebral artery occlusion (MCAO) by modulating MMP2/AQP4/APQ9 expression and inflammatory cell infiltration. Methods Eighty 8-week-old Sprague-Dawley rats were randomly divided into sham group S, MCAO model group M, acupuncture group A, electroacupuncture group EA, and edaravone group ED. The MCAO model was established by placement of a suture to block the middle carotid artery, and reperfusion was triggered by suture removal in all groups except group S. Acupuncture and electroacupuncture were administered at acupoints GV20 (governing vessel-20) and ST36 (stomach-36). Rats in groups A, EA, and ED received acupuncture, electroacupuncture, or edaravone, respectively, immediately after MCAO. Neurological function (assessed using the Modified Neurological Severity Score), infarct volume, MMP2/AQP4/AQP9 mRNA and protein expression, and inflammatory cell infiltration were all evaluated at 24 h post-reperfusion. Results Acupuncture and electroacupuncture significantly decreased infarct size and improved neurological function. Furthermore, target mRNA and protein levels and inflammatory cell infiltration were significantly reduced in groups A, EA, and ED vs. group M. However, MMP2/AQP levels and inflammatory cell infiltration were generally higher in groups A and EA than in group ED except MMP2 mRNA levels. Conclusions Acupuncture and electroacupuncture at GV20 and ST36 both exercised neuroprotective actions in a rat model of MCAO, with no clear differences between groups A and EA. Therefore, acupuncture and electroacupuncture might find utility as adjunctive and complementary treatments to supplement conventional therapy for ischemic stroke.
Group Action on Fuzzy Modules  [PDF]
Mohammad Yamin, Poonam Kumar Sharma
Applied Mathematics (AM) , 2016, DOI: 10.4236/am.2016.75038
Abstract: In this article, we introduce the notion of fuzzy G-module by defining the group action of G on a fuzzy set of a Z-module M. We establish the cases in which fuzzy submodules also become fuzzy G-submodules. Notions of a fuzzy prime submodule, fuzzy prime G-submodule, fuzzy semi prime submodule, fuzzy G-semi prime submodule, G-invariant fuzzy submodule and G-invariant fuzzy prime submodule of M are introduced and their properties are described. The homomorphic image and pre-image of fuzzy G-submodules, G-invariant fuzzy submodules and G-invariant fuzzy prime submodules of M are also established.
