Schizophrenia is a highly clinical and genetic heterogeneous disorder with complex background. Our previous study found chromodomain helicase DNA binding domain 5 (CHD5) rs1534997 contributes to paranoid schizophrenia risk. In this study, we examine whether this locus is also associated with schizophrenia with negative symptoms. To evaluate this correlation, we conducted a case-control study in 375 cases and 424 controls. Our study showed that rs1534997 does not play a crucial role in schizophrenia with negative symptoms. This study indicates that the rs1534997 polymorphism of the CHD5 gene is not involved in susceptibility to negative schizophrenia in Chinese.

In this article, an implementation of an ecient numerical method for solving the system of\ncoupled non-linear fractional diusion equations (NFDEs) is introduced. The proposed system\nhas many applications such as porous media and plasma transport and others. The fractional\nderivative is described in the Caputo sense. The method is based upon a combination between the\nproperties of the Chebyshev approximations and nite dierence method (FDM). The proposed\nmethod reduces NFDEs to a system of ODEs, which solved using FDM. Special attention is given\nto study the convergence analysis and deduce an error upper bound of the used approximate\nformula. Numerical example is given to show the validity and the accuracy of the proposed

In this paper, interval valued (or i-v) and bipolar fuzzy matrices are considered as matrices over a special type of semiring which is called path algebra. Some properties and characterizations for asymmetric and strongly complete(or s-complete) fuzzy matrices are established in a dual way. Also, we construct an idempotent i-v or bipolar fuzzy matrix from an s-complete fuzzy one through its adjoint matrix. Moreover, we show that this adjoint matrix is a generalized inverse of the originally i-v or bipolar fuzzy matrix.

This paper presents a structural analysis method for statically indeterminate beams under three different approaches: The first approach (Model 1) considers the bending deformations and shear in the methodology and in the fixed-end moments, this is the innovative part of this paper; The second approach (Model 2) takes into account the bending deformations and shear in the methodology, and considers the bending deformations in the fixed-end moments; The third approach (Model 3) is the slope-deflection classical method, which considers the bending deformations in the methodology and in the fixed-end moments. Also a comparison is made between the three approaches through three different problems for lengths of 5.00, 7.50, 10.00 m to observe differences. The results showed that differences between the three models, when members tend to be shorter, the differences are increased in proposed model (Model 1) with respect to the other two models. Therefore, the normal practice of using the Model 2 and Model 3, this is not a recommended solution, when lengths are short between supports. Then, the model 1 (proposed model) pass to be the more appropriate model for structural analysis of continuous beams and also is adjusted to the real conditions, since the shear forces and moments are present in any analysis of continuous beams and therefore the bending deformations and shear are produced.

This research studies the existence of the Fisher Effect in Europe with a very easy test, to verify if the most part of nominal interest rates changes are caused by inflation rate movements, remaining constant the real interest rate. Also, we split our sample into two subsamples. Thus, we distinguish two different periods: a first “expansion” period (1997-2007) and a second “crisis” period (2008-2012). Finally, we emphasize the main differences between two subsamples.

Considering the effects of transportation systems on citizens’ lives and the large amounts of funds required for their operation, it is essential to accuratly prioritize decisions for the development of urban transportation systems. Any misjudgement on this stage may cause a non-optimum decision and consequently impose considerable costs on the public. In this research, the Analytic Network Process (ANP) is selected for evaluation and prioritization of urban public transportation development scenarios. \nA new approach named “3-stages algorithm” is introduced in order to overcome some potential computational errors associated with network analysis process. \nA set of criteria were developed based on a brainstorming session and experts’ responses. The methodology is then applied to actual conditions of the public transportation in the city of Mashhad. Results show that 30% improvement is gained over conventional budget planning methoeds, which means increased benefit to cost ratios for the citizens. \nThe modified network analysis process is suggested for the assessment and prioritization of urban public transportation development scenarios as the result of this research.

In this paper, an energy efficient hybrid code combining technique is proposed for a cluster based cooperative wireless networks. Our scheme uses hybrid of selective repeat ARQ and low density parity check (LDPC) for code combining techniques. In the existing cluster based code combining techniques, energy consumption is more in the cluster heads and hence the energy level of the cluster head is drained before the data reaches the destination. In order to overcome this, a clustering technique is proposed in which the selection of cluster heads is based on the connectivity and the residual energy of each node. The clustering architecture consists of source cluster, destination cluster and relay clusters. Initially the ARQ technique is used as the code combining technique when the energy level of the nodes in cluster is more. The encoding and the decoding are done at each cluster using the LDPC codes until the data reaches the destination cluster. Using this technique, we can obtain immediate error recovery with less energy consumption and also better delivery ratio and minimum packet drop

Given the shortages of available water, specially for agricultural purposes, wastewater reuse prevents contamination of water as well as partially solving the current water shortage problems.This study aimed to determine the quality of wastewater effluent from the wastewater treatment plants (WTP) at Kashan University of Medical Sciences using the relationship between Total Suspended Solids )TSS( with Total Coliform )TC(, and Fecal Coliform )FC) for agricultural use.All samples were taken from thesanitary WTP effluent at Kashan University of Medical Sciences. Standardmethode were used for physiochemical and biological analysis of TSS,TC and FC.Results indicated that the value of R2 between TSS–FC and TSS–TC, regressions were; 0.78 and 0.79, respectively also, P-value was found less than 0.001 for the regressions in both cases.Therefore values of TC and FC could be estimated based on TSS parameter.Based on the results of present study a significant correlation between TSS, TC and FC parameters was observed in WTP effluent.

An effective method to avoid the electric power system from instability, frequency collapse and blackout is an under-frequency load shedding scheme. It is applied in order to maintain stability of the system, when the power system generation fails to supply the increase of load. Under-frequency load shedding scheme is a common technique to maintain the power system stability by curtailment of partial loads in some part of the system. This paper presents an under-frequency load shedding scheme by capturing the system frequency and rate of change of frequency for an islanded distribution network. The scheme is based on an adaptive under-frequency load shedding scheme. The disturbance magnitude is estimated by utilization of the transient behaviour of the system frequency. Dynamic simulation on an intentional islanding operation is performed on an existing Malaysia network. From simulation results, it can be clearly observe that the scheme reduces the power deficiency in islanded system, successfully
