Study on the Relationship between Postgraduate Student’s Emotion Regulation and Commit Suicide Attitude  [PDF]
Tingting Luo, Lin Lu, Xintian Zhu
Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.611122
Abstract: Aim: The high degree of group commit suicide phenomenon had been a social concern. The purpose of this paper was to try to understand how emotion regulation affected suicide attitude in graduate students. Method: 406 postgraduates in three universities of Chongqing were tested with Emotion Regulation Questionnaire (ERQ) and Suicide Attitude Questionnaire (QSA). Results: On the emotion regulation side, there were significant gender differences in revealing, and significant grade differences in rumination. When encountered with negative emotion, avoidance and suppression happened much more frequently than rumination and revealing. The latter two happened more frequently when postgraduates encountered positive emotions. On the suicidal attitude side, there were significant grade and professional differences in attitudes towards the suicide victims’ families and significant grade differences in euthanasia attitudes. Correlation analysis and regression analysis showed that suppressing negative emotion and avoiding positive emotion were important variables to affect graduate suicide attitude. Conclusion: Inappropriate emotional regulation might be an important reason for the postgraduates who approved of suicide.
Efficient algortihms for the two dimensional Ising model with a surface field

Physics , 2014, DOI: 10.1007/s10955-014-1109-5
Abstract: Bond propagation and site propagation algorithm are extended to the two dimensional Ising model with a surface field. With these algorithms we can calculate the free energy, internal energy, specific heat, magnetization, correlation function, surface magnetization, surface susceptibility and surface correlation. To test these algorithms, we study the Ising model for wetting transition, which is solved exactly by Abraham. We can locate the transition point accurately to $10^{-8}$. We carry out the calculation of the specific heat, surface susceptibility on the lattices with the sizes are up to $200^2 \times 200$. The results show that finite jump develops in the specific heat and surface susceptibility at the transition point as the lattice size increases. On the lattice with size $320^2 \times 320$ the parallel correlation length exponent is $1.88$, while in the Abraham's exact result it is $2.0$. The perpendicular correlation length exponent on the lattice with size $160^2\times 160$ is $1.04$, where its exact value is $1.0$.

Abstract: Stability conditions play an important role in the study of representations of a quiver. In the present paper, we study semistable representations of quivers. In particular, we describe the slopes of semistable representations of a tame quiver for a fixed stability condition.
Configural processing of different topologically structured figures: an ERP Study
JunJun Zhang,WeiNa Zhu,XiaoJun Ding,ChangLe Zhou,XinTian Hu,YuanYe Ma
Science China Life Sciences , 2009, DOI: 10.1007/s11427-009-0150-0
Abstract: According to Chen’s theory, topological differences are perceived faster than feature differences in early visual perception. We hypothesized that topological perception is caused by the sensitivity in discriminating figures with and without “holes”. An ERP experiment was conducted utilizing a passive paradigm to investigate the differences in perceiving figures with “hole” and with “no-hole”. The results showed differences in N170 components between figures with “holes” and with “no-holes”. The inversion of the “hole” could influence the latency of N170, but the inversion of the “no-hole” could not, which indicated that global features are processed first in the “hole” perception whilst local features are given priority to the “no-hole” perception. This result was similar to studies concerning face and non-face objects, suggesting a configural processing of the “hole”.

Numerical Simulation for General Rosenau-RLW Equation: An Average Linearized Conservative Scheme
Xintian Pan,Luming Zhang
Mathematical Problems in Engineering , 2012, DOI: 10.1155/2012/517818
Abstract: Numerical solutions for the general Rosenau-RLW equation are considered and an energy conservative linearized finite difference scheme is proposed. Existence of the solutions for the difference scheme has been shown. Stability, convergence, and a priori error estimate of the scheme are proved using energy method. Numerical results demonstrate that the scheme is efficient and reliable.
The critical 2-dimensional Ising model with fixed boundaries
Xintian Wu,Nickolay Izmailyan
Physics , 2014,
Abstract: The critical 2-dimensional Ising model is studied with four types boundary conditions: free, fixed ferromagnetic, fixed antiferromagnetic, fixed double antiferromagnetic. Using Bond Propagation algorithms with surface fields, we obtained the free energy, internal energy and specific heat numerically on square lattices with square shape and various combinations of the four types boundary conditions. The numerical data are analyzed with finite size scaling. The bulk, edge and corner terms are extracted very accurately. The exact results are conjectured for the corner logarithmic term in the free energy, the edge and corner logarithmic terms in the internal energy and specific heat. The corner logarithmic terms in the free energy agree with the conformal field theory very well.
The critical phenomena of a single defect
Xintian Wu,Yangyang Zhang
Physics , 2015, DOI: 10.1103/PhysRevE.92.032108
Abstract: We consider the critical system with a point defect and study the variation of thermodynamic quantities, which are the differences between those with and without the defect. Within renormalization group theory, we show generally that the critical exponent of the internal energy variation is the specific heat exponent of a pure system, and the critical exponent of the heat capacity variation is that for the temperature derivative of specific heat of a pure system. This conclusion is valid for the isotropic systems with a short-range interaction. As an example we solve the two dimensional Ising model with a point defect numerically. The variations of the free energy, internal energy and specific heat are calculated with bond propagation algorithm. At the critical point, the internal energy variation diverges with the lattice size logarithmically and the heat capacity variation diverges with size linearly. Near the critical point, the internal energy variation behaves as $\ln |t|$ and the heat capacity variation behaves as $|t|^{-1}$, where $t$ is the reduced temperature.

Convergence Theorems for Equilibrium Problems and Fixed-Point Problems of an Infinite Family of -Strictly Pseudocontractive Mapping in Hilbert Spaces
Haitao Che,Meixia Li,Xintian Pan
Journal of Applied Mathematics , 2012, DOI: 10.1155/2012/416476
Abstract: We first extend the definition of Wn from an infinite family of nonexpansive mappings to an infinite family of strictly pseudocontractive mappings, and then propose an iterative scheme by the viscosity approximation method for finding a common element of the set of solutions of an equilibrium problem and the set of fixed points of an infinite family of -strictly pseudocontractive mappings in Hilbert spaces. The results obtained in this paper extend and improve the recent ones announced by many others. Furthermore, a numerical example is presented to illustrate the effectiveness of the proposed scheme.
