TEHRAN, Iran (AP) -- Millions of Iranians voted late into the night Friday to decide whether incumbent President Hassan Rouhani deserves another four years in office after securing a landmark nuclear deal, or if the sluggish economy demands a new hard-line leader who could return the country to a more confrontational path with the West. The Islamic Republic's first presidential election since the 2015 nuclear accord drew surprisingly large numbers of voters to polling stations, with some reporting waiting in line for hours to cast their votes. Election officials extended voting hours at least three times at the more than 63,000 polling places to accommodate the crowds. Four candidates remain in the race. But for most voters only two mattered, both of them clerics with very different views for the country's future: Rouhani and hard-line law professor and former prosecutor Ebrahim Raisi. Rouhani is a political moderate by Iranian standards, but the 68-year-old has come to embody more liberal and reform-minded Iranians' hopes for greater political freedom at home and better relations with the outside world. His supporters are also hoping he can make better progress on improving the economy, a key issue on the minds of the country's 56 million eligible voters. Many say they are yet to see the benefits of the nuclear deal, which saw Iran limit its contested nuclear program over the objection of hard-liners in exchange for the lifting of some sanctions. Supreme Leader Ayatollah Ali Khamenei, the most powerful man in Iran, symbolically cast the election's first vote. He called for a large turnout, saying "the country is in the hands of all people." In Tehran, whose liberal and affluent voters form the bedrock of support for Rouhani, lines at some precincts were much longer than those in his 2013 win. Analysts have suggested a high turnout will aid Rouhani in securing a second four-year term. "I am happy I could vote for Rouhani," said Zohreh Amini, a 21-year-old woman studying painting at Tehran Azad University. "He kept the shadow of war far from our country." Voters who spoke to The Associated Press from the cities of Bandar Abbas, Hamadan, Isfahan, Rashat, Shiraz and Tabriz also described crowded polling places. The turnout may have spooked Raisi's camp, who filed a complaint to authorities over what they called "election violations" even before the polls closed, according to a report by the semi-official Tasnim news agency. Tehran Friday prayer leader Ayatollah Mohammad Ali Movahedi Kermani urged voters to elect someone who won't be a "hostage" to Western governments and their culture. "The next president should not be someone who makes the enemies happy when he is elected," said Kermani, who is an adviser to Khamenei. Rouhani has history on his side in the election. No incumbent president has failed to win re-election since 1981, when Khamenei himself became president. The 56-year-old Raisi, who heads an influential religious charitable foundation with vast business holdings, is seen by many as close to Khamenei. Raisi has even been discussed as a possible successor, though Khamenei has stopped short of endorsing anyone. Raisi won the support of two major clerical bodies and promised to boost welfare payments to the poor. His populist posture, anti-corruption rhetoric and get-tough reputation — bolstered by his alleged role condemning inmates to death during Iran's 1988 mass execution of thousands of political prisoners — hold appeal for conservative rural and working-class voters. "Rouhani has turned our foreign policies into a mess and damaged our religion," said Sedigheh Davoodabadi, a 59-year-old housewife in Iran's holy city of Qom who voted for Raisi. "Rouhani gave everything to the U.S. outright" in the nuclear deal. Both candidates urged voters to respect the outcome of the vote. Mostafa Hashemitaba, a pro-reform figure who previously ran for president in 2001, and Mostafa Mirsalim, a former culture minister, also remain in the race. Iranians overseas were also voting in over 300 locations, including 55 in the U.S., where more than 1 million Iranians live. Hard-liners remain suspicious of America, decades after the 1953 U.S.-engineered coup that toppled Iran's prime minister and the 1979 U.S. Embassy takeover and hostage crisis in Tehran. President Donald Trump's tougher stance on Iran has stoked concern as well, though his administration this week took a key step toward preserving the Obama-era nuclear deal. Iran's political system combines conservative clerical oversight and state control over large parts of the economy with tightly regulated but still hotly contested elections for key government posts. All candidates for elected office must be vetted, a process that excludes anyone calling for radical change, along with most reformists. No woman has ever been approved to run for president. The president of the Islamic Republic oversees a vast state bureaucracy employing more than 2 million people, is charged with naming Cabinet members and other officials to key posts, and plays a significant role in shaping both domestic and foreign policy. But he remains subordinate to the supreme leader, who is chosen by a clerical panel and has the ultimate say over all matters of state. The race has heated emotions and pushed public discourse in Iran into areas typically untouched in the tightly controlled state media. That includes Rouhani openly criticizing hard-liners and Iran's powerful Revolutionary Guard, a paramilitary force now involved in the war in Syria and the fight against Islamic State militants in neighboring Iraq. Rouhani also found his vehicle besieged by angry coal miners during a visit to a northern mine struck by a deadly explosion earlier this month. But authorities worry about tempers rising too high, especially after the 2009 disputed re-election of former hard-line President Mahmoud Ahmadinejad that saw unrest, mass arrests and killings. Authorities barred Ahmadinejad from running in Friday's election, and Khamenei warned this week that anyone fomenting unrest "will definitely be slapped in the face." That hasn't stopped those at Rouhani rallies from shouting for the release of the house-arrested leaders of the 2009 Green Movement. Opposition websites have said Green Movement leaders Mir Hossein Mousavi and Mahdi Karroubi both have endorsed Rouhani against Raisi. Rouhani promised in his 2013 campaign to free the men, but that pledge so far remains unfulfilled. Mohammad Khatami, another reformist who served as Iran's president from 1997 to 2005, also has endorsed Rouhani and received a raucous welcome when he voted, according to a clip shared on social media. Iranian authorities say they believe the vote will exceed a 70 percent turnout. Associated Press journalists Amir Vahdat in Tehran, Iran, Ebrahim Noroozi in Qom, Iran, and Jon Gambrell in Dubai, United Arab Emirates, contributed to this report.

Rationale: Sesamol, a natural compound with anti-inflammatory, antioxidant and neuroprotective properties, has shown promising antidepressant-like effects. However, its molecular target(s) have not been well defined, which merits further investigation. Objectives: Based on the interaction between the neurotrophin and endocannabinoid (eCB) systems and their contribution to emotional reactivity and antidepressant action, we aimed to investigate the involvement of nerve growth factor (NGF) and eCB signalling in the mechanism of action of sesamol. Methods: Following acute and 4-week intraperitoneal (i.p.) administration of sesamol (40, 80 and 100 mg/kg), the classical antidepressant amitriptyline (2.5, 5 and 10 mg/kg) or the benzodiazepine flurazepam (5, 10 and 20 mg/kg), brain regional levels of NGF and eCB contents were quantified in rats by Bio-Rad protein assay and isotope-dilution liquid chromatography/mass spectrometry, respectively. In the case of any significant change, the cannabinoid CB1 and CB2 receptor antagonists (AM251 and SR144528) were administered i.p. 30 min prior to the injection of sesamol, amitriptyline or flurazepam. Results: Following the chronic treatment, sesamol, similar to amitriptyline, resulted in the sustained elevation of NGF and eCB contents in dose-dependent and brain region-specific fashion. Neither acute nor chronic treatment with flurazepam altered brain NGF or eCB contents. Pretreatment with 3 mg/kg AM251, but not SR144528, prevented the elevation of NGF protein levels. AM251 exerted no effect by itself. Conclusions: Sesamol, similar to amitriptyline, is able to affect brain NGF and eCB signalling under the regulatory drive of the CB1 receptors. © 2013 Springer-Verlag Berlin Heidelberg.

Diagnosing pain mechanisms is one of the main approaches to improve clinical treatments. Especially, the detection of existence and/or level of pain can be vital when verbal information is not present for instant for neonates, disabled persons, anesthetized patients and also animals. Various researches have been performed to locate and classify pain, however, no consistent result has been achieved. The aim of this study is to show a strict relation between electroencephalogram (EEG) signal features and perceptual pain levels and to clarify the relation of classified signal to pain origin. Cortical regions on scalp were assigned based on an evolutional method for optimized alignment of electrodes that improve the clinical monitoring results. The EEG signals were recorded during relax condition and variety of pain conditions. Specific spectral features which are studied to show consistency with dynamical characteristic of EEG signals were combined with non-linear features including approximate entropy and Lyapunov exponent to provide the feature vector. Evolutionary optimization method was used to reduce the features space dimension and computational costs. A hybrid adaptive network fuzzy inference system (ANFIS) and support vector machine (SVM) scheme was used for classification of pain levels. ANFIS optimizer is used to fine tune the non-linear alignment of kernels of SVM. The results show that pain levels can be differentiated with high accuracy and robustness even for few recording electrodes. This research verifies the hypothesis that electrical variations of brain patterns can be used for determination of pain levels. The proposed classification method provided up to 95% accuracy. © 2012 Elsevier B.V. All rights reserved.

Energy Policy | Year: 2014

This paper attempts to explore the determinants of CO2 emissions using the STIRPAT model and data from 1980 to 2011 for OECD countries. The empirical results show that non-renewable energy consumption increases CO2 emissions, whereas renewable energy consumption decreases CO2 emissions. Further, the results support the existence of an environmental Kuznets curve between urbanisation and CO2 emissions, implying that at higher levels of urbanisation, the environmental impact decreases. Therefore, the overall evidence suggests that policy makers should focus on urban planning as well as clean energy development to make substantial contributions to both reducing non-renewable energy use and mitigating climate change. © 2013.

Forced vibrations of current-carrying nanowires in the presence of a longitudinal magnetic field are of interest. By considering the surface energy and size effects, the coupled equations of motion describing transverse motions of the nanostructure are derived. By employing Galerkin and Newmark-β approaches, the deflections of the nanowire subjected to transverse dynamic loads are evaluated. The effects of the magnetic field, electric current, pre-tension force, frequency of the applied load, surface and size effects on the maximum transverse displacements are discussed. The obtained results display that for the frequency of the applied load lower than the nanowire's fundamental frequency, by increasing the magnetic field or electric current, the maximum transverse displacements would increase. However, for exciting frequencies greater than that of the nanowire, maximum transverse displacements would increase or decrease with the magnetic field strength or electric current. Additionally, the pre-tension force results in decreasing of the maximum transverse displacements. Such a reduction is more apparent for higher values of the magnetic field strength and electric current. The present study would be useful in the design of the micro- and nano-electro-mechanical systems expected to be one of the most wanted technologies in the near future. © 2014 Elsevier B.V.

Voltage instability and collapse has been the subject of an increasing body of research over the past few years. In this paper, we proposed a new method of assessing static voltage stability in transmission and distribution networks. The proposed method (PM) is fast, accurate and robust. The expanded Newton-Raphson-Seydel (NRS) and Down-Hill (DH) algorithms are used in PM. Moreover, the elimination of the trigonometric terms in power flow equations and Jacobian matrix, will improve the convergence of PM algorithm. Standard CPF, CPF-GMRES and expanded NRS methods are compared to PM. These algorithms are tested on 350 bus transmission and 1316 bus distribution networks. © 2010 Praise Worthy Prize S.r.l. - All rights reserved.

Cloud computing is one of today's most exciting technology because of its cost-reducing, flexibility, and scalability. With the fast growing of cloud computing technology, Data security becomes more and more important in it. In evaluating whether to move to cloud computing, it is important to compare benefits and also risks of it. Thus, security and other existed issues in the cloud cause cloud clients need more time to think about moving to cloud environments. But Security-related topics is one of the most arguable issues in the cloud computing which caused several enterprises looks to this technology uncertainly and move toward it warily. In this paper I try to summarize cloud computing RAS (Reliability, Availability, and Security) issues and also clarify available solution for some of them. In this paper I try to summarize virtualization level of cloud computing security in detailed view. © 2011 IEEE.

Vehicular Adhoc network (VANET) is a new form of Mobile Adhoc Network (MANET). It integrates mobile connectivity protocols to expedite data transfer between vehicles as well as between roadside equipment and available traffic in network. In VANET, Wireless device sends information to nearby vehicles, and messages can be transmit from one vehicle to another vehicle. Therefore, using VANET can increase safety and traffic optimization. Similar to other technology, in VANET there are some important and noticeable issues. One of the most important of them is Security. Since the network is open and accessible from everywhere in the VANET radio range, it is expected to be an easy target for malicious users. In this paper, I try to discuss security issues as one of the most important problems in Vehicular Adhoc network. © 2011 IEEE.

Spherical involute surface topography for straight bevel gears including surface coordinates and normals are calculated. The significance of calculation of normal to the surface is mainly because it is needed for ease-off construction, tooth contact analysis and CMM measurement. The calculated surface and normals are then used to establish ease-off topography and the so-called surface of roll angle. The resultant surface of roll angle is used to allocate potential contact lines and contact ratio. The developed approach is applied to an example automotive differential straight bevel gear to calculate tooth surface, ease-off topography and surface of roll angle.

Cloud computing is one of today's most exciting technologies due to its ability to reduce costs associated with computing while increasing flexibility and scalability for computer processes. During the past few years, cloud computing has grown from being a promising business idea to one of the fastest growing parts of the IT industry. IT organizations have expresses concern about critical issues (such as security) that exist with the widespread implementation of cloud computing. These types of concerns originate from the fact that data is stored remotely from the customer's location; in fact, it can be stored at any location. Security, in particular, is one of the most argued-about issues in the cloud computing field; several enterprises look at cloud computing warily due to projected security risks. The risks of compromised security and privacy may be lower overall, however, with cloud computing than they would be if the data were to be stored on individual machines instead of in a so called cloud (the network of computers used for remote storage and maintenance). Comparison of the benefits and risks of cloud computing with those of the status quo are necessary for a full evaluation of the viability of cloud computing. Consequently, some issues arise that clients need to consider as they contemplate moving to cloud computing for their businesses. In this paper I summarize reliability, availability, and security issues for cloud computing (RAS issues), and propose feasible and available solutions for some of them. © 2011 IEEE.
