Complexity and Behind the Horizon Cut Off

Motivated by $T{\overline T}$ deformation of a conformal field theory we compute holographic complexity for a black brane solution with a cut off using "complexity=action" proposal. In order to have a late time behavior consistent with Lloyd's bound one is forced to have a cut off behind the horizon whose value is fixed by the boundary cut off. Using this result we compute holographic complexity for two dimensional AdS solutions where we get expected late times linear growth. It is in contrast with the naively computation which is done without assuming the cut off where the complexity approaches a constant at the late time.Comment: 14 pages, 2 figures, refs added, contribution of a counter term is added, minor correction, the final conclusion is not change

Robot localization in symmetric environment

The robot localization problem is a key problem in making truly autonomous robots. If a robot does not know where it is, it can be difficult to determine what to do next. Monte Carlo Localization as a well known localization algorithm represents a robot\u27s belief by a set of weighted samples. This set of samples approximates the posterior probability of where the robot is located. Our method presents an extension to the MCL algorithm when localizing in highly symmetrical environments; a situation where MCL is often unable to correctly track equally probable poses for the robot. The sample sets in MCL often become impoverished when samples are generated in several locations. Our approach incorporates the idea of clustering the samples and organizes them considering to their orientation. Experimental results show our method is able to successfully determine the position of the robot in symmetric environment, while ordinary MCL often fails

The Impact of Television and Short Message Service Advertising on Customer Behaviour and Brand Attitude

Marketing, advertising, and communications processes have changed to strategically capitalize on an increasingly digitally transformed, technologically empowered, globally interconnected consumer, or what service-dominant logic refers to as actors that are resource integrators. Customers are co-creators of value in the collaborative or sharing economy, and seek to actively reap the benefits of new knowledge growing at an exponential rate. However, developing models of customer behavior, especially the influence of a new kind of advertising based on the integrated use of television, web, and social networks, is a challenge. Our study starts from a preliminary empirical observation of the impact of television cooking shows on the variations of potential demand (queries on Google) and the purchase of branded/unbranded culinary products used on the show. Neural networks were used to determine significant correlations, which resulted in an operative Marketing 3.0 model. This model clearly explicates this impact factor on the consumer-purchasing process generated by a new mode of creating information and communications technology–based communication.

Fermions in non-relativistic AdS/CFT correspondence

We extend the non-relativistic AdS/CFT correspondence to the fermionic fields. In particular we study the two point function of a fermionic operator in non-relativistic CFTs by making use of a massive fermion propagating in geometries with Schrodinger group isometry. Although the boundary of the geometries with Schrodinger group isometry differ from that in AdS geometries where the dictionary of AdS/CFT is established, using the general procedure of AdS/CFT correspondence, we see that the resultant two point function has the expected form for fermionic operators in non-relativistic CFTs, though a non-trivial regularization may be needed.Comment: 12 pages,Latex file; V2: typos corrected, refs adde

The Impact of Electronic Advertising on the Cereal Importers' Decision to Buy

The purpose of this study was to investigate the effect of electronic advertising on the cereal importers' decision to buy. The present research is a causal descriptive-survey study and an applied study regarding the purpose. The statistical population of the present study is comprised of cereals importers in the first six months of the year 2016, which consist of 202 companies. Sample size was obtained through Cochran formula as 132, and then the questionnaire is distributed through random and classical sampling. The data was collected using two questionnaires: the pre-designed questionnaires was for evaluating electronic advertisement including 4 components and 20 questions, and a researcher-made questionnaire based on Philip Cutler's purchase decision theory to assess purchasing decision and consisted of 4 components, with 47 items. Both of the questionnaires were based on the five-degree Likert spectrum and their reliability was measured using the Cronbach's Alpha coefficient. The data collected through the questionnaire was entered into the spss19 software system. For the inferential statistics of variables to statistically analyze the data, different statistical tests including Kolmogorov-Smirnov test and Pearson correlation test and linear regression were used. The results of the research indicated that electronic advertising has a positive and significant effect on the decision making of cereal importers' purchase. Also, the dimensions of electronic advertising including banner, e-mail, web site, and search engines have a positive and significant effect on shoppers' e-shopping decision.

Assessment of the Preventive Effect of Pilocarpine on Radiotherapy-Induced Xerostomia in Patients with Head and Neck Cancers

Introduction Xerostomia is one of side-effects of radiotherapy for head and neck cancers. No definitive method has been proposed for the treatment of this condition. However, pilocarpine is considered effective for the management of chronic xerostomia. The purpose of the present study was to assess the preventive effect of pilocarpine. Materials and Methods This study was performed on 34 patients with head and neck cancers, undergoing radiation therapy (5000 cGy). The patients were randomly divided into two groups. The case group was administered 16 drops of pilocarpine (2%) eye drops per day, while the control group received normal saline; the treatment plan continued for four weeks. Unstimulated whole saliva flow rate was measured at four stages: two weeks before radiotherapy (baseline), the first day of radiotherapy, and two and four weeks after the initiation of radiotherapy. Results At baseline and the first day of radiotherapy, no significant differences were observed in the amount of saliva between the case and control groups (P<0.76 and P<0.054, respectively). However, by starting radiotherapy, a statistically significant improvement was reported in saliva production in the case group, compared to the control group (P<0.00); this trend continued during the next four weeks of radiotherapy (P<0.003). Generally, a significant difference was observed between the two groups at all stages of data evaluation (P<0.00). Conclusion According to the findings, pilocarpine was found to be effective for the prevention of xerostomia. Moreover, it could restrain the decline in the amount of saliva and reduce the rate of xerostomia

Expression of E-cadherin in primary breast cancer and its correlation with prognostic factors

Background and aim: Breast cancer is the most common malignancy in women and after lung cancer it is the second cause of death in women. Different biological markers are being used for determination of prognosis and patients’ responses to the therapy regimes. E-cadherin is one of these markers. The purpose of this study was to determine the frequency of E-cadherin expression in primary breast cancer and its correlation with the grade size of tumor and axillary lymph nodes involved. Methods: This cross –sectional study was performed on 85 patients with primary breast cancer who were admitted in Mostafa Khomeini Hospital in Tehran Iran (2003-2007). One section was prepared from the tumoral tissue and lymph nodes sections from all patients and they were stained with H & E. In another tissue section E-cadherin was evaluated by a immunohistochemical method and then the tumor size its grade and the number of lymph nodes involved were determined. The data were analyzed with SPSS software 11.5 using Chi-square Mann –Whitney and Spearman correlation tests. Results: Our data showed that 95.3% of the samples were positive for E-cadherin and 67.1% of the patients had lymph nodes involvement. The average size of the tumor was found 3.09±1.33 cm. In this study 41% of the tissue samples were stained with E-caherin more than 75% (3+). No significant relationship was found between E-cadherin expression and related variables but a significantly reverse relationship was found between E-cadherin expression and the grade tumor size and the number of lymph nodes involved (
