1 Forecasting client retention — A machine-learning approach
پیش بینی حفظ مشتری - یک رویکرد یادگیری ماشین-2020
In the age of big data, companies store practically all data on any client transaction. Making use of this data is commonly done with machine-learning techniques so as to turn it into information that can be used to drive business decisions. Our interest lies in using data on prepaid unitary services in a business-to-business setting to forecast client retention: whether a particular client is at risk of being lost before they cease being clients. The purpose of such a forecast is to provide the company with an opportunity to reach out to such clients as an effort to ensure their retention. We work with monthly records of client transactions: each client is represented as a series of purchases and consumptions. We vary (1) the length of the time period used to make the forecast, (2) the length of a period of inactivity after which a client is assumed to be lost, and (3) how far in advance the forecast is made. Our experimental work finds that current machine-learning techniques able to adequately predict, well in advance, which clients will be lost. This knowledge permits a company to focus marketing efforts on such clients as early as three months in advance.

2 The use of space-splitting RBF-FD technique to simulate thecontrolled synchronization of neural networks arising from brainactivity modeling in epileptic seizures
استفاده از روش تقسیم فضا RBF-FD برای شبیه سازی هماهنگ سازی کنترل شده شبکه های عصبی ناشی از مدل سازی میزان مغز در تشنج های صرع-2020
This paper investigates the behavior and synchronization of a network of reaction–diffusion neuraldynamics models using a highly efficient numerical method. In fact, the dynamical modeling, behav-ior analysis and controlled synchronization of a network of FitzHugh–Nagumo (FHN) neurons whichpromising the understanding of cognitive processing are studied by considering the unidirectional gapjunctions in the medium between two distant neurons. In this study, radial basis function generatedfinite differences (RBF-FD) technique is employed in conjunction with a suitable operator splitting tech-nique, which allows us to decouple the nonlinear partial differential equations of neural network modelsinto independent linear algebraic equations of very small dimensions. The most important advantagesof the proposed method can be high accuracy and high speed, very low computational complexity, andthe sparsity property of the matrix of the coefficients derived from its linear systems, which distinguishthe proposed method from other methods. The analyses and numerical results presented totally confirmthese claims.

3 Egocentric social network correlates of physical activity
شبکه اجتماعی خود محور وابسته به فعالیت فیزیکی-2017
Background: The social environment might play an important role in explaining people’s physical activity (PA) behavior. However, little is known regarding whether personal networks differ between physically active and physically inactive people. This study aimed to examine the relationship between personal network characteristics and adults’ physical (in)activity. Methods: An egocentric social network study was conducted in a random sample in Switzerland (n = 529, mean age of 53 years, 54% females). Individual and personal network measures were compared between regular exercisers and non-exercisers. The extent of these factors’ association with PA levels was also examined. Results: Non-exercisers (n = 183) had 70% non-exercising individuals in their personal networks, indicating homogeneity, whereas regular exercisers (n = 346) had 57% regularly exercising individuals in their networks, meaning more heterogeneous personal networks. Additionally, having more regular exercisers in personal networks was associated with higher PA levels, over and above individual factors. Respondents with an entirely active personal network reported, on average, 1 day of PA more per week than respondents who had a completely inactive personal network. Other personal network characteristics, such as network size or gender composition, were not associated with PA. Conclusion: Non-exercisers seem to be clustered in inactive networks that provide fewer opportunities and resources, as well as less social support, for PA. To effectively promote PA, both individuals and personal networks need to be addressed, particularly the networks of inactive people (e.g., by promoting group activities).

4 Using 3D vision camera system to automatically assess the level of inactivity in broiler chickens
استفاده از سیستم دید دوربین 3D به دسترسی اتوماتیک سطح عدم فعالیت در جوجه های گوشتی-2017
In this study, a new and non-invasive method was developed to automatically assess the lameness of broilers. For this aim, images of broiler chickens were recorded by a 3D vision camera, which has a depth sensor as they walked along a test corridor. Afterwards, the image-processing algorithm was applied to detect the number of lying events (NOL) based on the information of the distance between animal and the depth sensor of 3D camera. In addition to that, latency to lie down (LTL) of broilers was detected by 3D camera. Later on, the data obtained by proposed system were compared with visually assessed manual labelling data (reference method) and the relation between these measures and lameness was investi- gated. 93% of NOL were correctly classified by the proposed 3D vision camera system when compared to manual labelling using a data set collected from 250 broiler chickens. Furthermore, the results showed a significant correlation between NOL and gait score (R2 = 0.934) and a significant negative correlation between LTL and gait score level of broiler chickens (R2 = —0.949). Because of the strong correlations werefound between NOL, LTL and gait score level of broilers on the one hand and between the results obtainedby 3D system and manual labelling on the other hand, the results indicate that this 3D vision monitoring method can be used as a tool for assessing lameness of broiler chickens.© 2017 Elsevier B.V.

5 Health impacts of urban transport policy measures: A guidance note for practice
تاثیرات سلامتی از اقدامات سیاست حمل ونقل شهری: یک یادداشت راهنمایی برای تمرین-2017
Background: Urban transport related exposures and practices are associated with a significant burden of morbidity and premature mortality, which could be prevented by changing current practices. Cities now have access to an increasingly wide range of transport policy measures which continue to expand. However, the health impacts of these measures are not always ex plicitly defined or well understood and therefore may not be sufficiently considered when se lecting policy measures. Aims: The aim of this paper is to qualitatively review 64 different transport policy measures indexed in the Knowledgebase on Sustainable Urban Land use and Transport (KonSULT), and provide an indication of their potential health impacts, based on expert judgment. Results: We report that key health impacts of transport occur via pathways of motor vehicle crashes, traffic-related air pollution, noise, heat islands, lack of green space, physical inactivity, climate change and social exclusion and community severance. We systematically describe the expected health impacts of transport policy measures sourced from KonSULT and find that many, but not all, can have a positive impact on health. The magnitude of both the positive and negative impacts remains largely unknown and warrants further research and synthesis. Conclusions: Urban transport is responsible for a large mortality and morbidity burden and policy measures that are beneficial to health need to be implemented to reduce this burden. There are considerable differences between these policy measures in terms of potential health impacts and this should be considered in any transport planning. It is important to monitor the health impacts of all policy measures to provide further evidence on whether they work as expected or not, to ensure that the most cost-effective solutions, with the largest benefits and the smallest health risks, are being adopted.

6 Barriers to patient participation in a self-management and education website Renal PatientView: A questionnaire-based study of inactive users
موانع مشارکت بیمار در یک وب سایت خود مدیریتی و آموزشی مشاهده بیمار کلیوی: یک مطالعه مبتنی بر پرسشنامه از کاربران غیر فعال-2016
Objectives: The Renal PatientView (RPV) website is an information and education tool aimed at increasing patient involvement in their care. We have conducted this study to elucidate why some users remain inactive on RPV despite initially signing up for the service.
Methods: Patients at a teaching hospital in United Kingdom, who originally signed up for RPV but are no longer active (no logins during previous 6 months), were sent paper questionnaires. Responses were collected for up to 6 months.
Results: Of the 190 questionnaires, 69 (39%) were returned partially or fully completed. Majority of respondents could access computer (94%) and internet (91%) from home. Reasons for inactivity among
survey respondents included: loss of login credentials (45%), perception that it did not add anything to existing care (37%), being too busy (13%) and anxiety of viewing results from home (10%). Thirty-seven respondents provided free-text comments. Thematic analysis of these reinforced above findings and also indicated that despite infrequent use, some patients valued RPV availability. Patients made very little reference to using sections of the website other than test results.
Conclusions: Patients find RPV a valuable resource. It is, however, mainly seen as a portal to check blood test results; other sections of the website aimed at promoting self-management remain underutilized. Several local and central level changes, such as a robust system of user accounts handling, improved promotion, and emphasis on further development of self-management sections of RPV may help improve participation.
