With the expansion and spread of the Internet of Things, the ineffectiveness of the old encryption methods was proven. PUF was introduced as a hardware solution and is currently the best choice for securing IoT devices. The PUF structure based on the ring oscillator (RO-PUF) is one of the most well-known and desirable PUFs. It is also the best structure for the implementation of FPGA. Compared to other schemes, the responses generated by RO-PUF are the most reliable. This paper introduces an RO-PUF that provides maximum reliability, has a vast challenge-response pair (CRP) space, and is resistant to modeling attacks. A new comparator block is added to the CRO-PUF structure to evaluate the response bits and, when the value difference of the two counters is significant enough, to determine the stable response bits at the output. The proposed structure was implemented on the Xilinx FPGA board. The experiment shows that the proposed structure has ideal reliability, uniqueness, and uniformity close to the ideal value. This structure is resistant to modeling attacks due to its reconfigurability. Due to its maximum reliability and CRP, this structure can be the best choice for lightweight cryptographic applications.

Estimation of gaze direction is used in many fields such as psychology, criminology, advertising and market, computer games, human-machine interface and meta space. Each of the researches carried out in this field have somehow taken a step forward to fulfill this demand. We tried to fulfill the goal of estimating the gaze direction in a practical way for many domains. In this research, our goal is to estimate the user's gaze direction without the need for special and expensive hardware such as infrared sensors, high-quality cameras, and high-end processors on small display screens such as mobile phones, tablets, and laptops. In order to design the gaze direction estimator, different convolutional networks were used in a gaze direction estimator structure and then the results were obtained by training and comparison. Therefore, at this stage of the research, GazeCapture has been used as the dataset. The proposed model has an error of 1.12 cm without calibration. Finally, by grouping the data in the data set into two categories of data with bright ambient light and dark ambient light, the performance of the model in both lighting conditions has been checked and a method for improvement has been presented.

The aim of the present study was to examine the effect of group spiritual therapy on resilience in women with breast cancer.

The study method was quasi-experimental based on pre-test and post-test design with control group. The statistical population of this study was breast cancer patients referred to Taleghani Hospital in Tehran in 2016. Twenty-four subjects were selected randomly according to the inclusion criteria and were assigned to two groups of 12 randomly (experimental and control). Then, the experimental group was exposed to group spirituality with the protocol of therapy proposed by Richards and Berger (2005) for a period of 60 to 90 minutes weekly. Before and after 12 sessions of group therapy, both groups were tested by research instruments. Measured instruments included Structured Clinical Interviews for Axis I and II Disorders based on DSM-IV, and the Kunner & Davison Resiliency Questionnaire (CD-RISC, 2003). Covariance analysis was used to analyze the collected data.

Findings of this study showed that spirituality therapy had a positive effect on mental status and disease control in different samples.

The results showed that spiritual therapy group increased the resilience of the experimental group in comparison with the mean of the control group. Also the difference between the scores of experimental group and control group or the effect of spiritual therapy group (η2 = 0.763), ie 76% difference in post-test resiliency scores, was related to spiritual therapy group.

This research is the question of Turkey’s Justice and Development Party dynamics in external fields for the region is based on the fundamental principles, to conclude that Turkey through ideological attitudes of the Cold War, a new attitude in politics its exterior is defined. Turkey can also view it in the context of a dynamic and significant part of what it is to achieve its elite imagination, already an important and integral part of the foreign policy, has become a. Turkey’s foreign policy is also shown as evidence of, the result of this attitude in foreign policy, and pursuing the creation of efficient and effective strategies for dealing with equations and how to deal with the great powers of the Middle East. Helped the country’s geopolitical position. Indeed, the AKP to power in Turkey creates changes in the foreign policy  principles, including the promotion of regional issues in the Middle East for her and out of the West used to. On the other hand, due to the failure of Europe to join the union tries Prrngkrdn with emphasis on the region and its regional role of Western  governments to take more points. In this paper an attempt has been made to the analytical - descriptive and based on the documents and resources to investigate the dynamics Turkish foreign policy towards the Middle East region, Erdogan’s government discussed with emphasis on the period and place of this region after to explain the rise of the AKP.

In this paper, a new current mode four-quadrant analog multiplier circuit is proposed. The circuit structure is based on dual trans-linear loops. The new structure used in the circuit shows more promising features for the purposes of lower power consumption, wider bandwidth (BW), and lower Total Harmonic Distortion (THD). The structure of the circuit is such that it is almost independent of process, temperature, and supply-voltage, PVT, variations. In addition, the circuit was optimized using Multi-Objective Genetic Algorithm (MOGA) and the results demonstrate the power of this tool in the optimization of electronic circuits. The designed circuit with 1.8 V supply voltage and 53 μW power consumption, results in 1.503 GHz BW, 0.53% THD (in 1 MHz frequency) and also 0.84% maximum nonlinearity error.
