A MODELLING OF ELBOW FLEXION AND CALCULATION OF MUSCLE MOMENT AND THE REACTION FORCE ON ELBOW USING ADAMS SOFTWARE

In this research elbow flexion has been analysed and the moment of muscles and the reaction force exerted on the elbow is calculated in the range of motion. The moment of muscles indicate the performance of movement and the reaction force of the joint is believed to be one of the most important causes of damage, something which hasn’t been studied thoroughly enough in previous researches. To that end, we use ADAMS software which is one of the most powerful ones available in dynamics analyses. The results indicate that the maximum torque of the arm occurs at 96 degrees and it decreases in the beginning and the end of flexion. The reaction force of the elbow in the beginning of motion is at maximum amount and then decreases to 107 degrees, and from that point on it increases up to the end of the motion. These results indicate that the optimum range of elbow flexion occurs in the mid-range of flexion, approximately at 58-140 degrees

Joint Inference of Structure and Diffusion in Partially Observed Social Networks

Access to complete data in large scale networks is often infeasible. Therefore, the problem of missing data is a crucial and unavoidable issue in analysis and modeling of real-world social networks. However, most of the research on different aspects of social networks do not consider this limitation. One effective way to solve this problem is to recover the missing data as a pre-processing step. The present paper tries to infer the unobserved data from both diffusion network and network structure by learning a model from the partially observed data. We develop a probabilistic generative model called "DiffStru" to jointly discover the hidden links of network structure and the omitted diffusion activities. The interrelations among links of nodes and cascade processes are utilized in the proposed method via learning coupled low dimensional latent factors. In addition to inferring the unseen data, the learned latent factors may also help network classification problems such as community detection. Simulation results on synthetic and real-world datasets show the excellent performance of the proposed method in terms of link prediction and discovering the identity and infection time of invisible social behaviors

Perfect Secrecy Using Compressed Sensing

In this paper we consider the compressed sensing-based encryption and proposed the conditions in which the perfect secrecy is obtained. We prove when the Restricted Isometery Property (RIP) is hold and the number of measurements is more than two times of sparsity level i.e. M \geq 2k, the perfect secrecy condition introduced by Shannon is achievable if message block is not equal to zero or we have infinite block lengthComment: 3 page

Evaluation of Leptin and Adiponectin Levels in Patients with Stable Angina Pectoris

<p class="abstract"><strong>BACKGROUND:</strong> Leptin and adiponectin are two adipose tissue hormones and their association with the incidence of cardiovascular diseases is under evaluation. The aim of this study was to determine the relationship of leptin and adiponectin with coronary artery diseases.</p> <p class="abstract"><strong>&nbsp;&nbsp; METHODS:</strong><strong> </strong>One hundred and seventy patients with angina pectoris and indications of coronary angiography underwent angiography. Serum levels of blood lipids, leptin, and adiponectin were measured. The gathered data was evaluated using SPSS software, V. 15, by multivariate variance analysis.</p> <p class="abstract"><strong>&nbsp;&nbsp; RESULTS:</strong> Analysis of the data demonstrated that 45.1% of the patients had positive angiographic findings. The serum levels of leptin and adiponectin were significantly lower than the minimum levels specified by the kit. However, the two groups, i.e., patients with positive angiographic findings and those with negative findings were not significantly different according to the serum levels of the hormones. Moreover, no significant correlation between the serum levels of the hormones and serum lipids was observed.<strong>&nbsp;</strong></p> <p class="abstract"><strong>&nbsp;&nbsp; </strong><strong>CONCLUSION:</strong> Various studies have demonstrated that high serum level of leptin and the incidence of coronary artery diseases are correlated. On the other hand, they have reported that adiponectin has cardioprotective role. Confirmation of these findings requires more detailed studies.</p> <p class="abstract">&nbsp;</p><table cellspacing="0" cellpadding="0" align="left"><tbody><tr><td width="35" height="12"><br /></td></tr> <tr><td><br /></td> <td>&nbsp;</td></tr></tbody></table><strong>Keywords:</strong> Leptin, Adiponectin, Coronary artery disease<br /

Comparing the Quality of Iodine in Edible Salt in Iranian Households Living in the Southern Province of Khorasan-e-Razavi Using WHO Standards (Years 2010–2015)

Iodine deficiency disorder among Iranians is a major health-related issue. The aim of this study was to determine iodine concentration in household salt. To sample the iodized salt products, the authors visited all wholesale warehouses of two cities of Bajestan and Gonabad in Khorasan-Razavi, Iran, and randomly purchased three packages of each brand of factory salt distributed through those centers. The sampling procedure was continued over the course of five years (2010–2015). In the 5-year study period, 82 samples of 23 different brands of factory salt were sampled. The most frequent samples were classified into three groups based on their iodine content (ppm = mg iodine per kg of salt): under standard limit (<20 ppm); allowable standard limit (20–50 ppm); over standard limit (>50 ppm). The tests showed that 67% of samples maintained a good level, 26.8% possessed an acceptable level, and 6% had unacceptable levels of iodine. Mean and standard deviation of the salt iodine content were 24.7 and 13.7, respectively. According to the results, the iodine content of samples showed significant differences with international standards (40 ppm), and this highlights the necessity of stricter monitoring of the salt production
