Abbas Sadeghi, Seyed Hamed Mousavian
Advances in Physical Education (APE) , 2018, DOI: 10.4236/ape.2018.81007
Abstract: The main objective?of?this?study was to compare learning styles, resiliency and problem solving skills in Iranian chess players. The approach?of?this?study was a description of cohesion kind. The statistical population included all active chess players with an international rating under chess federation supervision of Islamic Republic of Iran. The sample was based on Morgan table, and the sampling was done by simple method and the number of 306 players was?chosen who answered the learning style questionnaire of Clop in2005,Kaner& Davidson’s Resiliency in 2003, and Kasidi& Long’s problem solving?guideline in 1996. The data obtained by Chi-square Test, Kolmogorov-Smirnov Test (KS test), Kruskal-Wallis Test & Spearman correlation Test analyzed by SPSS21. The findings showed that there wasn’t a significant relationship between learning styles with the amount of resiliency and chess players’ problem solving skills. Also there was a positive and powerful relation between the amount of resiliency and chess players solving problem skills. It seems that chess players learning style doesn’t have any effect on the ability of problem-solving skill. In other word,?having learning style and different thinking?isn’t an advantage
Effective Factors in Green Supply Chain Management and Natural Environment Developed in Iran Tourism Industry:The Case of Small and Medium Tour Operators
Shahram Gilaninia,Seyed Yahya Seyed Danesh,Seyyed Javad Mousavian
International Journal of Business Administration , 2011, DOI: 10.5430/ijba.v2n2p155
Abstract: Tourism for all citizens of the world and the vital is to provide sustainable employment. In this regard, most attention of governments and their management resources to the tourism and pristine natural environment or green has been focused on other aspects of the industry, although also Country managers see gone away, but to protect and maintain environmental capacity most important challenges the countries in this field covers. Although the structure of the tourism sector crumbled a key challenge in order to reach a consensus on coherent development theory sustainability left is involved. But evidence from theoretical studies indicate that supply chain strategies as a logical time for nature online tourism industry in all its dimensions seem appropriate, limited debate in tourism research related to the acceptance there. Present paper advance knowledge of how sustainable tourism can be more public acceptance in practice of supply chain management in the tourism environment (ESCMT) by medium and small brokers in small and medium-sized tour operating in Iran deals. The results show that in the absence of regulatory pressures and cost savings, acceptance (ESCMT) in small and medium tourist enterprises will be very effective. Result of research for government executives and managers tourism agencies appropriate guidelines to be drawn.
Finite size scaling approach to dynamic storage allocation problem
Hamed Seyed-allaei
Computer Science , 2003, DOI: 10.1016/S0378-4371(03)00509-0
Abstract: It is demonstrated how dynamic storage allocation algorithms can be analyzed in terms of finite size scaling. The method is illustrated in the three simple cases of the it first-fit, next-fit and it best-fit algorithms, and the system works at full capacity. The analysis is done from two different points of view - running speed and employed memory. In both cases, and for all algorithms, it is shown that a simple scaling function exists and the relevant exponents are calculated. The method can be applied on similar problems as well.
Three Bead Rotating Chain model shows universality in the stretching of proteins
Hamed Seyed-allaei
Quantitative Biology , 2004, DOI: 10.1103/PhysRevE.72.041908
Abstract: We introduce a model of proteins in which all of the key atoms in the protein backbone are accounted for, thus extending the Freely Rotating Chain model. We use average bond lengths and average angles from the Protein Databank as input parameters, leaving the number of residues as a single variable. The model is used to study the stretching of proteins in the entropic regime. The results of our Monte Carlo simulations are found to agree well with experimental data, suggesting that the force extension plot is universal and does not depend on the side chains or primary structure of proteins.
Phase Diagram of Spiking Neural Networks
Hamed Seyed-allaei
Quantitative Biology , 2013, DOI: 10.3389/fncom.2015.00019
Abstract: In computer simulations of spiking neural networks, often it is assumed that every two neurons of the network are connected by a probability of 2\%, 20\% of neurons are inhibitory and 80\% are excitatory. These common values are based on experiments, observations, and trials and errors, but here, I take a different perspective, inspired by evolution, I systematically simulate many networks, each with a different set of parameters, and then I try to figure out what makes the common values desirable. I stimulate networks with pulses and then measure their: dynamic range, dominant frequency of population activities, total duration of activities, maximum rate of population and the occurrence time of maximum rate. The results are organized in phase diagram. This phase diagram gives an insight into the space of parameters -- excitatory to inhibitory ratio, sparseness of connections and synaptic weights. This phase diagram can be used to decide the parameters of a model. The phase diagrams show that networks which are configured according to the common values, have a good dynamic range in response to an impulse and their dynamic range is robust in respect to synaptic weights, and for some synaptic weights they oscillate in $\alpha$ or $\beta$ frequencies, even in absence of external stimuli.

Australian Journal of Business and Management Research , 2011,
Abstract: The main objective of this research was to investigate the relationship between employee creativity and organizational effectiveness in educational organizations of East Azerbaijan and Ardabil provinces. This investigation was an applied research using a descriptive methodology with correlation tests. The statistical population for this research included all employees of East Azerbaijan and Ardabil provinces in 2010, comprising 45 and 19 departments, respectively, or a total of 64 departments. Using Morgan table for estimation of sample size, and according to random sampling method, 56 departments (29 and 17 departments, respectively) with 297 employees (179 and 118 employees, respectively) were selected, and were tested using simple random technique. Data collection was performed using two questionnaires, for which validity and reliability testing had been performed previously. The creativity questionnaire was filled by organizational employees, while the organizational effectiveness questionnaire was filled by executives of educational departments. In this research, according to the objectives of the research, descriptive statistics was used for creation of frequency tables and charts and computation of suitable central indices, while the study hypothesis was tested using Pearson’s correlation test. The results of this investigation showed that there is a statistically significant relationship between employee creativity and organizational effectiveness in educational departments of East Azerbaijan and Ardabil provinces (p < 0.05).

Lysosome: As a Proposed Target for Rose Bengal in Inducing Cell Death in Melanoma Cells
Seyed Hadi Mousavi,Seyed Hamed Moosavi
Iranian Journal of Medical Hypotheses & Ideas , 2008,
Abstract: We have previously shown that rose bengal (RB) itself and not as a photosensitiser could induces dual modes of cell death in melanoma cells and has clinical activity against melanoma. But the mechanisms of RB-induced cell death are unclear. Recently lysosome was reported to initiate different kinds of cell death including necrosis, caspase-dependent and -independent apoptosis. The hypothesis of this study is to investigate the role of lysosome in mediating RB-induced cell death in melanoma cells focusing on lysosomal protease cathepsin B (CB). We present two lines of evidence indicating a central role for the CB in mediating cell death. First, inhibition of CB would result in a strong protection against drug-induced cell death and apoptosis in melanoma cells. Simultaneous inhibition of caspases would determine that CB acts upstream or downstream the caspase cascade. Second, we show RB triggers disruption of lysosomes leading to release and activation of CB using an engineered yellow fluorescent protein-tagged CB. It is hypothesized that RB-induced cell death in melanoma cells is mediated through lysosomal CB in this novel cell death pathway. This idea points to a new tumor-suppressive role for lysosomes which may be less affected by chemotherapy-induced resistance mechanisms.
