  In this paper, the sensitivity of a plasmonic nanodipole antenna array for different materials of the metal nanodipole and substrate is calculated by changing the refractive index of the surrounding medium. The performance of our proposed array is studied at two wavelengths of 1310 and 1550 nm, the wavelengths of the second and third telecommunications windows. It is shown that by using the silver (Ag) nanodipole instead of the gold (Au) one, the bulk sensitivity of the nanostructure is improved. By replacing the substrate material from Si to SiO2, the sensitivity increases up to 1220 and 1150 nm/RIU at the wavelengths of 1310 and 1550 nm, respectively, that is very suitable for sensing applications. Moreover, the figure of merit (FoM) of the plasmonic sensor is calculated for both substrates and nanodipole materials. The maximum value of the FoM is obtained for the nanoantenna array with SiO2 substrate and Ag nanodipole and it is equal to 14.35. Furthermore, it is shown that by increasing the thickness of the nanodipole, the nanostructure sensitivity and FoM are enhanced Manuscript profile

  Applying a proper management on water resources by identifying vulnerable areas as the first solution can be useful. The purpose of this study was to assess the vulnerability in the central plain of Guilan with drastic model. To identify the vulnerable areas of the central plain of the Guilan plain to pollution, drastic model was used and an aquifer vulnerability map was developed. The principles of the drastic model are based on the combination of seven components, depth to static level, net nutrition, aquifer environment, soil environment, topography, unsaturated environment, and hydraulic conductivity, which after ranking and applying weight impact on each component and algebraic composition of seven components, the final result will indicate the aquifer vulnerability. For this purpose, first, the information of the seven components in the central aquifer of Guilan was collected, and after entering in the GIS software, the layers needed for the model were finally prepared. Then, by using overlapping techniques after applying the required weight coefficients for each layer, a final vulnerability map was prepared. The profile of the drastic model varied from 82 to 182 for the vulnerability of the central aquifer of Guilan. The final drastic model map showed that 48.64% of the area had a high vulnerability and 50.55% had moderate vulnerability and only a small area of the plain (0.81%) had a low vulnerability. Based on the sensitivity method of map removal and single component and using the Monte Carlo technique, the depth distance to the station level was identified as the most effective component and saturation zone as the second most effective component in the central plain of Guilan.

  In this study, the optimized DRASTIC model parameters and land use layer (LU) were used to assess specific vulnerability in Kashan aquifer using statistical methods. Information layers were prepared, rated (deterministic and fuzzy-statistical), weighted (original and statistical) and combined (by Index-Overlay method) in GIS environment. For optimization of DRASTIC model, nonlinear regression for fuzzy-statistical rating (scaling) and Pearson correlation coefficients between nitrate concentrations and scaling parameters of DRASTIC model and sensitivity analysis (removal and single-parameter) were performed to determine and modify weighted parameters. As a result, RASIC-LU model with statistical rating and weighting, single-parameter sensitivity analysis, determined the best selection model based on correlation coefficient = 61.1%, P-Value= 0.001 and with parameters of net recharge, aquifer media, soil media, impact of vadose zone, hydraulic conductivity and land use with weight values of 2.50, 4.63, 4.15, 3.03, 1.96 and 2.00 respectively. According to this model, western and southern parts of the aquifer has a high and very high pollution risk due to high net recharge, pollutant land use and coarse-grain material in the impact of vadose zone, soil and aquifer media. In addition, sensitivity analysis based on mean squares error (MSE) indicated that this model is more sensitive to removal and increase of parameters weight of land use, soil media, impact of vadose zone, aquifer media, net recharge and hydraulic conductivity, and shows a decreasing ternd, respectivily.

  Writing of present research aims to investigate strategies in the course of reducing black record of crimes against children and to discover and reveal such offences in terms of their vulnerability. This study has been conducted using descriptive- analytical method and by means of librarian references. The conducted studies about this topic may interpret that due to some various reasons, the victimized children may not report the offences perpetrated against their own and as a consequence not only have not they been supported by what anticipated in law, but also they are undergone double injuries by secondary and repeated victimization. The child victims, who are called as ‘silent victims’ and or ‘suffering in silence’, should have potential to reflect the offences perpetrated on them and led to breach their rights in order to enjoy criminal supports and otherwise. Thus, it has been tried in this paper to display image of requisite for culture-building and public sensitivity to recognize basic rights for children and to report the infringement cases of such rights as well as their right of expression of victimization and right of hearing (in the court) in order to break silence in children and also to acquire trust from the victimized children in criminal justice system through providing some facilities in proceeding process. Such measures result in further discovery and revealing of crimes against children Manuscript profile

  Child labor is one of the social ills of today's society. This study aimed to investigate a structural model of unconditional self-acceptance, rejection sensitivity, future expectations, and childhood experience care in working children. A correlational design using structural equation modeling was conducted. The statistical population of this study include the working child who lived in Yazd and Isfahan cities in 2020. A total of 160 children was selected using available sampling methid and answered to Chamberlin and Haaga’s unconditional self acceptance cale, Downey and Feldman’s sensitivity to rejection scale, Mcwhirter’s future expectations scale, and Bifulco, Brown and Harris’s childhood experience of care questionnaire. The findings showed that unconditional acceptance had a negative and significant effect on sensitivity to rejection (P<0.05). Childhood experience of care had a negative and significant relationship with future expectations while being positively and significantly related to sensitivity to rejection. Likewise, rejection sensitivity had a significant and negative effect on future expectations (P<0.05). The results did not support the direct effect of unconditional acceptance on future expectations. Regarding the results, it can be concluded that improving childhood care, reducing sensitivity to rejection, and working on the unconditional acceptance of these children, helped to improve their lives.

  Load shedding is the last line of defense for controlling and stabilizing of the power system in the occurrence of a disturbance. Determining the amount and location of the load shedding are issues that the power system operators always have faced In this paper, a new method is proposed for determining the location of under voltage load shedding (UVLS). The proposed method, unlike the previous UVLS methods, uses two different factors to determine the effective location of UVLS. Considering the load reactive power in the process of determination of the UVLS location leads to disconnecting more reactive power during the initial steps of UVLS. Therefore, less active power sheds by the UVLS. To verify the accuracy of the proposed method, the proposed UVLS method accompanied with the method which uses the sensitivity of voltage with respect to the active power are implemented in IEEE 118-bus test system and New England 39 bus system. The obtained results show the superiority of the proposed method. Manuscript profile

  Estimation of formation water saturation (Sw) using log data is an important approach in the oil exploration and characterization of a hydrocarbon reservoir. Therefore, it seems that the proper prediction/simulation of Sw is essential. The first objective of this study was to develop a predictive model for Sw estimation based on hybrid cluster analysis with piecewise nonlinear regression, and after that, using the developed model, Sw was simulated by the Monte Carlo simulation (MCS). In order to achieve objectives of this study, a group of 909 data points was used for model construction and 302 data points were employed for assessment of model. The obtained results of MCS modeling indicated that this approach is capable of simulating Sw ranges with a good level of accuracy. The mean of simulated Sw by MCS was obtained as 0.28 m, while this value was achieved as 0.29 m for the measured one. Furthermore, a sensitivity analysis was also conducted to investigate the effects of model inputs on the output of the system. The analysis demonstrated that RHOB is the most influential parameter on Sw among all model inputs. It is noticeable that the proposed hybrid cluster analysis with piecewise nonlinear regression and MCS models should be utilized only in the studied area and the direct use of them in the other conditions is not recommended.

  The purpose of this research was to determine the mediating role of metacognitive beliefs between anxiety sensitivity, responsibility and obsessive-compulsive symptoms in the general population living in Tehran. The descriptive research method was correlation type (path analysis). 300 people from among the general population living in Tehran city were selected through an internet call, according to the entry criteria in the accessible sampling method. The tools used in this research include the Revised Obsession Scale (OCI-R); (Foua et al., 2002), Anxiety Sensitivity Inventory (ASI) (Rice et al., 1986), Responsibility Attitude Scale (RAS); (Salkovskis et al., 2000) and metacognitive beliefs questionnaire (MCQ-30); (Wells, 1997). The data showed that anxiety sensitivity and responsibility have a direct and significant relationship with obsessive-compulsive symptoms, and metacognitive beliefs have a mediating role in the relationship between anxiety sensitivity and responsibility with obsessive-compulsive symptoms, and the indirect effect of metacognitive beliefs in the relationship between anxiety sensitivity, Responsibility and obsessive-compulsive symptoms were significant.In general it can be concluded that anxiety sensitivity and responsibility can cause the emergence and continuation of obsessive-compulsive symptoms by increasing metacognitive beliefs. According to the research results and the mediating role of metacognitive beliefs in relation to obsessive-compulsive symptoms, planning to improve people's education in the field of anxiety sensitivity and responsibility can play an important role in reducing obsessive-compulsive symptoms through metacognitive beliefs.

  Screening tests are a special type of diagnostic tests that are performed in an apparently healthy population. The purpose of performing diagnostic tests is to correctly diagnose patients, distinguish affected animals from healthy animals, distinguish between cases and controls, and distinguish between normal and abnormal cases. Screening tests should be simple, cheap, rapid and valid. Diagnostic and screening tests are mainly used in the monitoring of diseases. Related terms to the evaluation of these tests, including sensitivity, specificity, positive and negative predictive value, accuracy and precision, as well as concepts such as the golden standard, because they are often used interchangeably or misinterpreted, it is especially important to learn them. Also, due to the fact that gold standard tests are often more expensive and time-consuming, incomplete diagnostic tests are used, which can be calculated by calculating the sensitivity and specificity of the actual and apparent prevalence obtained by the diagnostic test. However, if the golden standard test is not available, other methods are used to evaluate the tests, including the Kappa index test. The interpretation results of these tests provide a comprehensive and evidence-based approach to clinicians and experts, which ultimately leads to more accurate, comprehensive, cheaper and faster monitoring. In this review article, with a complete and comprehensive review of the conventional concepts in the evaluation of diagnostic tests, along with the solution of practical examples, we will expand and provide a comprehensive presentation of these concepts. Also, the latest original studies that have been done in the field of evaluation of diagnostic tests will also be reviewed in this article. Manuscript profile
