Optimality for Multi-Objective Programming Involving Arcwise Connected d-Type-I Functions  [PDF]
Guolin Yu, Min Wang
American Journal of Operations Research (AJOR) , 2011, DOI: 10.4236/ajor.2011.14028
Abstract: This paper deals with the optimality conditions and dual theory of multi-objective programming problems involving generalized convexity. New classes of generalized type-I functions are introduced for arcwise connected functions, and examples are given to show the existence of these functions. By utilizing the new concepts, several sufficient optimality conditions and Mond-Weir type duality results are proposed for non-differentiable multi-objective programming problem.
Blunt Traumatic Pericardial Rupture
—Case Report and Literature Review
 [PDF]

Hongbin Wang, Min Li
Surgical Science (SS) , 2013, DOI: 10.4236/ss.2013.410086
Abstract:

Pericardial rupture following blunt chest trauma is rare and associated with high mortality rate ranging from 30% to 64%. We review 42 cases which have been reported in the literature in last 17 years and report a case of our own. We have found that 83% of the cases were men with a mean age of 49 years. The most frequent cause was traffic accidents (79%). Preoperative diagnosis of traumatic rupture of the pericardium has been improved in recent 17 years, and the result is satisfactory. Early detection, timely treatment is the key. Pneumopericardium may be a valuable radiographic clue for diagnosis. The management of pericardial rupture is mainly to avoid the risk of cardiac strangulation or acute tamponade. If the injury is recognized timely, treatment is simple and effective.

Expression of Telomerase Reverse Transcriptase during the Malignant Transformation of Cadmium-Induced Cells  [PDF]
Min Wang, Yixiong Lei
Journal of Geoscience and Environment Protection (GEP) , 2014, DOI: 10.4236/gep.2014.22018
Abstract: The objective of the present study was to investigate human telomerase reverse transcriptase (hTERT) mRNA and protein expressions during the cadmium chloride-induced malignant transformation of human bronchial epithelial (16HBE) cells. Fluorescence quantitative PCR (FQ-PCR) and Western blot analyses were performed to detect the hTERT mRNA and protein expressions in normal 16HBE cells, cadmium chloride-transformed 16HBE cells, and tumorigenic cells from nude mice inoculated with cadmium chloride-transformed 16HBE cells. Under the inner standard of GAPDH, the hTERT mRNA expression was significantly higher at different stages of malignant transformation (cadmium chloride-transformed 16HBE cells at passages 15 and 35 and tumorigenic cells from nude mice) than in normal 16HBE cells, and increased with the development of malignancy (P < 0.01). In addition, hTERT protein expression increased with the development of malignancy. These findings demonstrate that hTERT expression is related to cadmium chlorideinduced malignant transformation. Cadmium chloride-induced malignant transformation is involved in changes in the hTERT activity, and might be an early event in cadmium chloride-induced malignant transformation.

Breeding of NHase hyper-producing Rhodococcus ruber strain LUV30-06 and verification of mutants by RAPD  [PDF]
Shiwei Wang, Min Wang, Qinghui Wang
American Journal of Molecular Biology (AJMB) , 2013, DOI: 10.4236/ajmb.2013.32015
Abstract:

A nitrile hydratase (NHase) hyper-producing Rhodococcus ruber strain LUV30-06 was bred by mutagenization on the starting strain CGMCC3090 with ultraviolet irradiation and lithium chloride. The NHase activity of the strain LUV30-06 was increased by 21.99% (3881.3 U/ml), as compared with that of R. ruber CGMCC3090 (3181.4 U/ml). The mutant strain UV30-06 has been proved genetically stable with higher NHase activity in seven successive subcultures as well as random amplified polymorphic DNA analysis (RAPD).

Asian Social Science , 2012, DOI: 10.5539/ass.v8n15p108
Abstract: This study aims to: 1) describe the effects of cooperative learning (CL ) on achievement motivation of female college students, and 2) compare the difference in the achievement motivation between the female college students learning through cooperative learning and those learning through the traditional learning pattern. In this study , an intervention program was devised as part of a new learning style to encourage the performance of physical education and achievement motivation in which students (mean age =21.2years, N= 67) were invited to participate as part of physical classes. The questionnaire were completed as pre-test at the beginning of the intervention for overall the treated and control groups and as post-tests at the end of week twelve. T test measures were used to examine whether there were significant differences of achievement motivation within the two groups. The results showed that the cooperative learning classes to improve the achievement motivation among the female college students.
Quantum Mechanics in the general quantum systems (VI): exact series solution of stationary Schr?dinger's equation
An Min Wang
Physics , 2009,
Abstract: We obtain a complete series solution of stationary Schr\"odinger's equation in the general quantum systems. It is exact in the sense that any approximation means is not used, or that the whole corrections or contributions from all order perturbations are involved if the perturbation concept is introduced. Furthermore, the useful forms of our exact solution and a new expression the complete Green operator are given out. As a universal and analytical solution, it is helpful for the theoretical derivations and practical calculations in quantum theory.
Quantum mechanics in general quantum systems (II): Perturbation theory
An Min Wang
Physics , 2006,
Abstract: We propose an improved scheme of perturbation theory based on our exact solution [An Min Wang, quant-ph/0611216] in general quantum systems independent of time. Our elementary start-point is to introduce the perturbing parameter as late as possible. Our main skills are Hamiltonian redivision so as to overcome a flaw of the usual perturbation theory, and the perturbing Hamiltonian matrix product decomposition in order to separate the contraction and anti-contraction terms. Our calculational technology is the limit process for eliminating apparent divergences. Our central idea is ``dynamical rearrangement and summation" for the sake of the partial contributions from the high order even all order approximations absorbed in our perturbed solution. Consequently, we obtain the improved forms of the zeroth, first, second and third order perturbed solutions absorbing the partial contributions from the high order even all order approximations of perturbation. Then we deduce the improved transition probability. In special, we propose the revised Fermi's golden rule. Moreover, we apply our scheme to obtain the improved forms of perturbed energy and perturbed state. In addition, we study an easy understanding example of two-state system to illustrate our scheme and show its advantages. All of this implies the physical reasons and evidences why our improved scheme of perturbation theory are actually calculable, operationally efficient, conclusively more accurate. Our improved scheme is the further development and interesting application of our exact solution, and it has been successfully used to study on open system dynamics [An Min Wang, quant-ph/0601051].
Quantum mechanics in general quantum systems (I): Exact solution
An Min Wang
Physics , 2006,
Abstract: Starting from our idea of combining the Feynman path integral spirit and the Dyson series kernel, we find an explicit and general form of time evolution operator that is a $c$-number function and a power series of perturbation including all order approximations in the unperturbed Hamiltonian representation. Based on it, we obtain an exact solution of the Schr\"{o}dinger equation in general quantum systems independent of time. Comparison of our exact solution with the existed perturbation theory makes some features and significance of our exact solution clear. The conclusions expressly indicate that our exact solution is obviously consistent with the usual time-independent perturbation theory at any order approximation, it explicitly calculates out the expanding coefficients of the unperturbed state in the non-perturbation method, and it fully solves the recurrence equation of the expansion coefficients of final state in the unperturbed Hamiltonian representation from a view of time-dependent perturbation theory. At the same time, the exact solution of the von Neumann equation is also given. Our results can be thought of as theoretical developments of quantum dynamics, and are helpful for understanding the dynamical behavior and related subjects of general quantum systems in both theory and application. Our exact solution, together with its sequence studies on perturbation theory [An Min Wang, quant-ph/0611217] and open system dynamics [An Min Wang, quant-ph/0601051] can be used to establish the foundation of theoretical formulism of quantum mechanics in general quantum systems. Further applications of our exact solution to quantum theory can be expected.
