	1. Microstructure evolution mechanism in adiabatic shear band in TA2

	Abstract:The microstructure evolution mechanism in adiabatic shear band in commercial pure titanium (TA2) at high strain rate ( ≈105~106/s) were studied. The nanosized recrystallized grains (about 50 nm in diameter) within the center of adiabatic shear band (ASB) were observed by means of transmission electronic microscope (TEM). A Rotational Dynamic Recrystallization (RDR) mechanism can explain the microstructure evolution (ie. nanosized grains was formed within 5-10μs) in ASB. Kinetics calculations indicated that the recrystallized small grains were formed during the deformation and didn’t undergo significant growth by grain boundary migration after deformation.

	3. On the Complexity of a Combined Homotopy Interior Point Method for Convex Programming
	Bo Yu,Qing Xu,Guochen Feng
	Mathematics 27 February 2004
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:In [1],[2] and [8], a combined homotopy was constructed for solving non-convex programming and convex programming with weaker conditions, without assuming the logarithmic barrier function to be strictly convex and the solution set to be bounded. It was proven that a smooth interior path from an interior point of the feasible set to a K-K-T point of the problem exists. This shows that combined homotopy interior point methods can solve the problem that commonly used interior point methods can't solve. However, so far, there is no result on its complexity, even for linear programming. The main difficulty is that the objective function is not monotonically decrease on the combined homotopy path. In this paper, by taking a piecewise technique, under commonly used conditions, polynomiality of a combined homotopy interior point method is given for convex nonlinear programming.

	Abstract:The transaction creation that counteracted by the endogenetic transaction cost can be partly eliminated by the reputation of enterprises through the way of signaling, mortagaging and assuring. Chinese listed company’s reputation and the situation of governance has tight relations. This paper selects the data of 249 companies out of 406 investigated samples. It performs an empirical study on the reputations of enterprises and the governance of stakeholders, in order to give some ideas on the construction of reputations of Chinese listed companies.

	6. Study on Influence of Cyclodextrins on the Photolysis of Dissolved Anthracene by Fluorescence Spectroscopy

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract: In this paper, a simple, fast and effective fluorescent method for studying the photolysis of dissolved anthracene (An) in cyclodextrins (CDs) aqueous solutions was developed. With this method the influences of five kinds of CDs on the photolysis of dissolved An were investigated. It was found that all five CDs have promotive effects on the photolysis of An. It was due to the incorporation of An into the CDs cavities which inhibited self-quenching of triplet-state An and prolonged the lifetime of singlet-state An. These enhanced the possibility of attack of oxygen to An and more singlet-state oxygens were produced. The effects of cavity sizes and steric hindrance of substituents of CDs on photolysis of An were explored. The order of capacity for promotion of various CDs was as follows：hydroxypropyl-β-CD （HPCD）> heptakis(2,6-di-O-methyl)-β-CD (DMCD)>β-CD>γ-CD>α-CD.

	Abstract:A series of extended-conjugation N-Aryl pyrrolo [3,4-d] annulated tetrathiafulvalene derivatives (3a-d)were synthesized via cross coupling of 4,5-diethyl- thio-1,3-dithiole-2- one with N-aryl-(1,3)-dithiolo[4,5-c]pyrrole-2- thiones (10a-d), the later were obtained by the ring closing reaction of 4,5-bis(bromomethyl)-1,3-dithiole-2- thione (7) and aromatic amines(8a-d). We also studied electrochemical behavior of 3a-d by means of Cyclic Voltammetry. All these compounds have comparable or lower half-wave potentials than those of N-alkyl-pyrrolo[3,4-d] annulated tetrathiafulvalene derivatives (2a-c) which have been reported previously .

	8. Multiple solutions to a Caffarelli-Kohn-Nirenberg type equation with asymptotically linear term

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:In this paper, we study the existence of multiple solutions to a Caffarelli-Kohn-Nirenberg type equation with asymptotically linear term at infinity. In this case, the well-known Ambrosetti-Rabinowtz type condition doesn't hold, hence it is difficult to verify the classical (PS)$_c$ condition. To overcome this difficulty, we use an equivalent version of Cerami's condition, which allows the more general existence result.

	10. The eigenvalue problem of a singular quasilinear elliptic equation

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:In this paper, we shall study the eigenvalue problem of a singular quasilinear elliptic equation. We will show that many results about the eigenvalues and eigenfunctions in the non-singular case can be extended to the more general singular case, e.g., the first eigenvalue $\lambda_1$ is associated to a $C^{1,\alpha}(\Omega)$ eigenfunction which is positive in $\Omega$ and unique (up to a multiplicative constant), that is, $\lambda_1$ is simple. Moreover $\lambda_1$ is isolated, and is the unique positive eigenvalue associated to a non-negative eigenfunction. Finally, we should prove some variational properties of the second eigenvalue $\lambda_2$.
