THE RELATIVISTIC COVARIANCE OF ONNES EQUATION

Liu Ze-wen,Zhu Zhen-long,Meng Xiang-jun,

中国物理 B , 2000,
Abstract: On the assumption that Onnes equations meet the requirements of the relativistic covariance, virial coefficients as functions of temperature are derived by using the transformations between thermodynamic variables provided by the vector theory of relativistic thermodynamics, and result in agreement with those obtained from cluster expansions in statistics. This breaks, to some extent, the traditional ideas that the thermodynamic theory is not able to derive equations of state at all and presents a possibly simple and new way of finding theoretically the equation of state.

Abstract: 最近,Dai和Wang分别给出了一种基于Schnorr签名体制的指定签名验证者的代理签名方案,但是,在Dai的文献中所采用的代理签名方案并不安全;Wang在文献中所采用的代理签名方案虽然克服了Dai方案中的缺点,但该方案中代理签名人和授权者在产生代理签名密钥时交互过多,因而效率比Dai的方案低。因此通过利用Schnorr签名体制生成代理签名人的私有参数和公开参数,给出了一种新的代理签名方案,该方案不仅克服了Dai和Wang方案的缺点,而且更为安全、简单和有效

Abstract: We in this paper strictly prove that some block diagonalizable two qubit entangled state with six none zero elements reaches its quantum relative entropy entanglement by the a separable state having the same matrix structure. The entangled state comprises local filtering result state as a special case.

Abstract: There are two singularities in atmospheric governing equations under spherical coordinate system,and hence,velocity at the north and south poles can not be defined and predicted directly by grid-point atmospheric model. To solve this problem,a simple approach is presented,and an explicit square conservation scheme in A-grid for shallow water model is chosen as an example. The new approach defines pole velocity and sets up a difference equation. The new model can predict pole velocity directly,and the numeri...

Abstract: The traffic signal control schemes are put in the form of rule-sets into use through fuzzy classifying the arrived cars in this paper. Genetic algorithm is applied to improve the rule-sets according to the effect of actual controlling. These procedures form a new machining-learning traffic signal control approach for isolated intersection. After simulating, the control effect of this new approach with fixed-time control method and actuated control method are compared. The result of simulating illustrates that the effect of the new approach is obviously better than the traditional ones.
Anti-N-methyl-D-aspartate receptor encephalitis: a new autoimmune encephalitis
CHEN Xiang-jun,LI Xiang
Chinese Journal of Contemporary Neurology and Neurosurgery , 2013, DOI: 10.3969/j.issn.1672-6731.2013.01.005
Abstract: Anti-N-methyl-D-aspartate (anti-NMDA ) receptor encephalitis is a new category of treatable encephalitis associated with anti-NMDA receptor antibody, which attracts more and more attention recently. It is clinically characterized by prodromal fever, schizophrenia-like psychiatric symptoms, seizures, disturbance of consciousness, dyskinesia (particularly orofacial), and autonomic dysfunction, which often occur in young females with ovarian teratomas. Autoantibodies to the anti-NMDA receptor in serum and cerebrospinal fluid are positive. Electroencephalogram (EEG) often reveals diffuse δ slowing without paroxysmal discharges, on which " δ rush" is considered as specific characteristic in some patients. Combined therapy including tumor resection and immunotherapy is recommended. The updates in mechanisms, clinical manifestations and diagnostic examinations associated with anti-NMDA receptor encephalitis will be discussed in this review.
Calculating adiabatic evolution of the perturbed DNLS/MNLS solitons
Xiang-Jun Chen,Wa Kun Lam
Physics , 2004, DOI: 10.1016/j.physleta.2005.02.030
Abstract: A symbolic computation technique is developed to calculate adiabatic evolution equations for parameters of the perturbed DNLS/MNLS solitons obtained by the recently developed direct perturbation theory [X.-J. Chen and J. Yang, Phys. Rev. E {\bf 65}, 066608(2002)]. Effects of the intrapulse Raman scattering, third-order group velocity dispersion, and narrow-banded filters with nonlinear gain on the MNLS solitons are studied as examples.

Abstract: The calcium-tolerant rat ventricular myocytes were isolated by enzyme digestion. Action potentials and Ito of epicardial, mid-cardial and endocardial ventricular myocytes were recorded by whole-cell patch clamp technique.1. Action potential durations (APDs) were prolonged from epicardial to endocardial ventricular myocytes (P < 0.05). 2. Ito current densities were decreased from epicardial to endocardial ventricular myocytes, which were 59.50 ± 15.99 pA/pF, 29.15 ± 5.53 pA/pF, and 12.29 ± 3.62 pA/pF, respectively at +70 mV test potential (P < 0.05). 3. APDs were gradually prolonged with the increase of DHA concentrations from 1 μmol/L to 100 μmol/L, however, APDs changes were not significant as DHA concentrations were in the range of 0 μmol/L to 1 μmol/L. 4. Ito currents were gradually reduced with the increase of DHA concentrations from 1 μmol/L to 100 μmol/L, and its half-inhibited concentration was 5.3 μmol/L. The results showed that there were regional differences in the distribution of action potentials and Ito in rat epicardial, mid-cardial and endocardial ventricular myocytes. APDs were prolonged and Ito current densities were gradually reduced with the increase of DHA concentrations.The anti-arrhythmia mechanisms of DHA are complex, however, the effects of DHA on action potentials and Ito may be one of the important causes.Fatty acids, especially polyunsaturated fatty acids (PUFAs), play an important role in life and death of cardiac cells. Reasons are as follow: 1. they are essential fuels for mechanical, electrical, and synthetic activities of the heart; 2. their levels are abnormally high in an ischemia followed by a reperfusion; and 3. dietary fish oil is apparently beneficial for heart function [1,2]. Therefore, the beneficial effects of PUFAs on cardiovascular diseases, such as fish oil, have been reported, and the effects of PUFAs on anti-arrhythmias and prevention of sudden death have been highlights [3-6]. It has been reported that PUFAs have the ro

Abstract: Through the analysis of related literatures at home and abroad about the measurement of urbanization level and its dynamic changes,we found that China's urbanization has entered a rapid development stage and the motive forces for the development of urbanization have changed enormously.Therefore,the scientific measurement of urbanization development level and quantitative comparative analysis of its ideal powers will be particularly important to promote the level and quantity of regional urbanization.Based on the urbanized connotation,the paper constructs the appraisal index system of the synthesis level of the regional urbanization embarking population urbanization,economic urbanization,life-style urbanization and regional landscape urbanization.With the method of entropy,the generalized analyses to the evolution of the urbanization level of Jiangsu Province from 1991 to 2005 are carried out.The result shows that the urbanization of Jiangsu Province has been enhanced continuously.At the same time,the urbanization mainly represents the fast development of the economic urbanization and the regional landscape urbanization.But the population urbanization is becoming weak to the overall contribution of the regional urbanization and lagging behind other urbanizations.Economic urbanization,life-style urbanization and regional landscape urbanization have improved constantly.Meanwhile,they are turning harmonious gradually.On this basis,the multiple linear regression models are linked to the comparative analysis of the main urbanized impetus of Jiangsu Province from 1991 to 2005.Then the result is that the market forces,the intrinsic forces,the exterior forces and the administrative forces are the main powers of the urbanization development of Jiangsu Province.And the market forces and administrative forces are the ideal powers that promote the urbanization and the economic development of Jiangsu Province.
