Predicting the dose absorbed by organs at risk during intensity modulated radiation therapy for nasopharyngeal carcinoma
Authors: Pang Haowen , Sun Xiaoyang , Yang Bo , Wu Jingbo 
Published: July 2018

Objective:
To develop a model for predicting the dose absorbed by organ at risk (OAR) during intensity modulated radiation therapy for nasopharyngeal carcinoma (NPC).

Methods:
55 patients underwent intensity modulated radiation therapy for NPC. The OARs were divided into several suborgans, and SPSS software was used to evaluate multiple linear method for fitting the normalized volume for each suborgan, normalized mean dose (Dmean) Dnm (Dnm = Dmean/Dprescription), and normalized D10%−D100% values Dn10% − n100%(Dn10%−n100% = D10%−D100%/Dprescription) for each OAR. Based on the Matlab software, the predicted Dn10%−n100% value was fitted to obtain the predicted DVH curve.

Results:
The multiple linear fitting formulas revealed significant results for the oral cavity Dn100% (p = 0.017), the parotid gland Dn100% (p = 0.001), and the remaining OAR (all p &lt; 0.0001). The correlation coefficients and p values indicated that the fitting formula was a good fit. The p values for the White test show that the prediction model is robust. This method was successfully used for verification cases.

Conclusion:
The present study provided a simple and effective model for predicting the dose absorbed by OAR for NPC.

Advances in knowledge:
This method is a relatively simple mathematical model, just use prescription dose and V0–Vn to predict the Dmean and D10%−100%, which predict does not require buying new modules of treatment planning software or extracting the distance of each sampling point of the OAR with the dose information.
When Discounts Hurt Sales: The Case of Daily-Deal Markets
Authors: Cao Zike , Hui Kai-Lung , Xu Hong 
Published: July 2018

We investigate whether the discounts offered by online daily deals help attract consumer purchases. By tracking the sales of 19,978 deals on Groupon.com and conducting a battery of identification and falsification tests, we find that deep discounts reduce sales. A 1% increase in a deal’s discount decreases sales by 0.035%–0.256%. If a merchant offers an additional 10% discount from the sample mean of 55.6%, sales could decrease by 0.63%–4.60%, or 0.80–5.24 units and $42–$275 in revenue. This negative effect of discount is more prominent among credence goods and deals with low sales, and when the deals are offered in cities with higher income and better education. Our findings suggest that consumers are concerned about product quality, and excessive discounts may reduce sales immediately. A follow-up lab experiment provides further support to this quality-concern explanation. Furthermore, it suggests the existence of a “threshold” effect: the negative effect on sales is present only when the discount is sufficiently high. Additional empirical analysis shows that deals displaying favorable third-party support, such as Facebook fans and online reviews, are more susceptible to this adverse discount effect. We draw related managerial implications. The online appendix is available at https://doi.org/10.1287/isre.2017.0772 .
Measurement of the Uniformity of Thermally Bonded Points in Polypropylene Spunbonded Non-Wovens Using Image Processing and its Relationship With Their Tensile Properties
Authors: Emadi Mina , Tavanaie Mohammad Ali , Payvandy Pedram 
Published: July 2018

Abstract
This article aims at the image processing of surface uniformity and thermally bonded points uniformity in polypropylene spunbonded non-wovens. The investigated samples were at two different weights and three levels of non-uniformity. An image processing method based on the k-means clustering algorithm was applied to produce clustered images. The best clustering procedure was selected by using the lowest Davies-Bouldin index. The peak signal-to-noise ratio (PSNR) image quality evaluation method was used to choose the best binary image. Then, the non-woven surface uniformity was calculated using the quadrant method. The uniformity of thermally bonded points was calculated through an image processing method based on morphological operators. The relationships between the numerical outcomes and the empirical results of tensile tests were investigated. The results of image processing and tensile behavior showed that the surface uniformity and the uniformity of thermally bonded points have great impacts on tensile properties at the selected weights and non-uniformity levels. Thus, a sample with a higher level of uniformity and, consequently, more regular bonding points with further bonding percentage depicts the best tensile properties.

Published: July 2018

Abstract
A newly self-developed electronic nose (E-nose) system for the detection of “Hongyan” strawberry freshness at different storage periods was studied. The system consisted of six metal oxide semiconductor sensors connected to a data acquisition system and a computer with pattern recognition software. The aroma emitted by “Hongyan” strawberry samples was detected during post-harvesting storage, and stable E-nose response values were used to develop cluster analysis and classification models. The successive projections algorithm was employed to optimize the sensors array, and the results obtained by gas chromatography–mass spectrometry analysis proved that the optimized sensor array was feasible to differentiate decayed strawberries from fresh ones. Partial least squares discriminant analysis and support vector machine (SVM) models were built. Accuracy of 94.9 % on the testing set was obtained based on the optimized sensor array, and this result was satisfactory compared to that of commercial PEN3 E-nose.

Uncovered Interest Rate Parity: The Turkish Evidence
Authors: Öge Güney Pelin 
Published: July 2018

AbstractThis paper presents an empirical investigation of the uncovered interest parity (UIP) between the Turkish Lira (TRY)/US Dollar (USD) and Turkish Lira/Euro (EUR). Our results do not provide evidence supporting the UIP hypothesis for either case. Moreover, the estimates imply causality from the TRY/USD exchange rate return to the interest rate differential. Accordingly, the Turkish Central Bank (CBRT) may respond by increasing the domestic interest rate to a depreciation of the TRY against the USD . By taking this type of action, it can be concluded that the CBRT tried to control capital movements. This result supports (McCallum, Bennett T. 1994. “A Reconsideration of the Uncovered Interest Parity Relationship.”Journal of Monetary Economics33 (1): 105–132.)’s argument, which advances the behavior of the monetary policy as a reason for the failure of the UIP condition.
Investment on human capital in a dynamic contest model
Authors: Keskin Kerim , Sağlam Çağrı 
Published: July 2018

AbstractAlthough most contest games are modeled in such a way that the outcome depends only on the efforts exerted by the contestants, what is arguably more important is the contestants’ effective efforts which may be influenced also by their ability, human capital, strength, etc. In this paper, we investigate an extensive model including such an effectiveness parameter and analyze the optimal investment behavior in a dynamic conflict framework. At each period, two contestants compete for a common prize by choosing contest efforts and investment levels. Each contestant’s investment accumulates as his/her human capital which depreciates through time. Who wins the component contest at a particular period is determined by the contestants’ effective efforts, defined as increasing functions of their efforts and human capitals. Following the analysis of subgame perfect Nash equilibrium in a two-period model and of open-loop equilibrium in an infinite-horizon model, we provide intuitive comparative static results.

Pareja-Blanco, F, Rodríguez-Rosell, D, Aagaard, P, Sánchez-Medina, L, Ribas-Serna, J, Mora-Custodio, R, Otero-Esquina, C, Yáñez-García, JM, and González-Badillo, JJ. Time course of recovery from resistance exercise with different set configurations. J Strength Cond Res 34(10): 2867–2876, 2020—This study analyzed the response to 10 resistance exercise protocols differing in the number of repetitions performed in each set (R) with respect to the maximum predicted number (P). Ten males performed 10 protocols (R(P): 6(12), 12(12), 5(10), 10(10), 4(8), 8(8), 3(6), 6(6), 2(4), and 4(4)). Three sets with 5-minute interset rests were performed in each protocol in bench press and squat. Mechanical muscle function (countermovement jump height and velocity against a 1 m·s−1 load, V1-load) and biochemical plasma profile (testosterone, cortisol, growth hormone, prolactin, IGF-1, and creatine kinase) were assessed at several time points from 24-hour pre-exercise to 48-hour post-exercise. Protocols to failure, especially those in which the number of repetitions performed was high, resulted in larger reductions in mechanical muscle function, which remained reduced up to 48-hour post-exercise. Protocols to failure also showed greater increments in plasma growth hormone, IGF-1, prolactin, and creatine kinase concentrations. In conclusion, resistance exercise to failure resulted in greater fatigue accumulation and slower rates of neuromuscular recovery, as well as higher hormonal responses and greater muscle damage, especially when the maximal number of repetitions in the set was high.

Abstract
Buskard, AN, Oh, J, Eltoukhy, M, Brounstein, SR, and Signorile, JF. A novel method to determine optimal load in elastic-based power training. J Strength Cond Res 32(9): 2401–2408, 2018—The benefits of muscular power on sport performance and older adults' abilities to live independently and resist falls is well documented. Consequently, a substantial volume of research has focused on establishing the optimal loading patterns for improving muscular power using resistance exercise; however, to date, this research has only targeted optimal loading during training with free weights or selectorized exercise machines. Conversely, no approach has been developed to establish optimal loads for elastic modalities, such as tubes and bands, commonly used for sports rehabilitation, injury prevention, and training older adults. Therefore, the purpose of this study was to evaluate a new method for determining the optimal tubes to use in power training performed with elastic resistance. Thirty-eight recreationally active college students (age, 23.7 ± 4.5 years) were recruited to perform 3 single-arm bicep curls at a maximum intended velocity using 6 elastic tubes of varying resistance. Testing was performed in a 3-dimensional (3D) motion analysis laboratory using a specially constructed platform with an integrated strain gauge to which each tube was anchored. Force data from the strain gauge and velocity data from the 3D motion capture system were then used to compute power for each tube. An analysis based on individual’s cable arm curl 1-repetition maximum (1RM) was then used to generate general guidelines for the most appropriate tube to use for arm curl power training based on upper arm 1RM. Our results demonstrate the feasibility of using this methodology for other exercises, thereby establishing optimal tube use for power training based on each exercise's 1RM.
Tandem Duplicate Genes in Maize Are Abundant and Date to Two Distinct Periods of Time
Authors: Kono Thomas J Y , Brohammer Alex B , McGaugh Suzanne E , Hirsch Candice N 
Published: July 2018

AbstractTandem duplicate genes are proximally duplicated and as such occur in similar genomic neighborhoods. Using the maize B73 and PH207 de novo genome assemblies, we identified thousands of tandem gene duplicates that account for ∼10% of the annotated genes. These tandem duplicates have a bimodal distribution of ages, which coincide with ancient allopolyploidization and more recent domestication. Tandem duplicates are smaller on average and have a higher probability of containing LTR elements than other genes, suggesting origins in nonhomologous recombination. Within relatively recent tandem duplicate genes, ∼26% appear to be undergoing degeneration or divergence in function from the ancestral copy. Our results show that tandem duplicates are abundant in maize, arose in bursts throughout maize evolutionary history under multiple potential mechanisms, and may provide a substrate for novel phenotypic variation.

Authors: Yuknis Matthew L. , Weinstein Elizabeth , Maxey Hannah , Price Lori , Vaughn Sierra X. , Arkins Tom , Benneyworth Brian D. 
Published: July 2018

BACKGROUND:
Management of pediatric emergencies is challenging for ambulatory providers because these rare events require preparation and planning tailored to the expected emergencies. The current recommendations for pediatric emergencies in ambulatory settings are based on 20-year-old survey data. We aimed to objectively identify the frequency and etiology of pediatric emergencies in ambulatory practices.

METHODS:
We examined pediatric emergency medical services (EMS) runs originating from ambulatory practices in the greater Indianapolis metropolitan area between January 1, 2012, and December 31, 2014. Probabilistic matching of pickup location addresses and practice location data from the Indiana Professional Licensing Agency were used to identify EMS runs from ambulatory settings. A manual review of EMS records was conducted to validate the matching, categorize illnesses types, and categorize interventions performed by EMS. Demographic data related to both patients who required treatment and practices where these events occurred were also described.

RESULTS:
Of the 38 841 pediatric EMS transports that occurred during the 3-year period, 332 (0.85%) originated from ambulatory practices at a rate of 42 per 100 000 children per year. The most common illness types were respiratory distress, psychiatric and/or behavioral emergencies, and seizures. Supplemental oxygen and albuterol were the most common intervention, with few critical care level interventions. Community measures of low socioeconomic status were associated with increased number of pediatric emergencies in ambulatory settings.

CONCLUSIONS:
Pediatric emergencies in ambulatory settings are most likely due to respiratory distress, psychiatric and/or behavioral emergencies, or seizures. They usually require only basic interventions. EMS data are a valuable tool for identifying emergencies in ambulatory settings when validated with external data.
Contemporary Catholic Studies in a Secular University: Friend or Foe?
Authors: Briliute Birute 
Published: July 2018

Through the introduction of a new hermeneutical model of communication in RE, this article intends to explore an innovative approach to developing Christian identity in a secular university. The author holds a joint lectureship in religious education, catechesis and pastoral theological education. Religious education and catechesis are concerned with all aspects of the teaching of religion in schools, within the parish and any other pastoral setting. pastoral theological education is concerned with the place of learning within religious communities and the larger society. This distinction has resulted in this research proceeding along two parallel routes: the institutional educational environment, religious communities and society as a background influencing our value change as well as the way we do RE in schools. The main concern of the author is to develop practical ways of enhancing the Catholic religious identity and theological literacy of students in the state secondary schools and universities in the UK, on the basis of contemporary theological anthropology and educational theoretical foundations. This article is an investigation into a new understanding of the development of Catholic identity and new models of RE used in a contemporary secular university.
Il pensiero pedagogico italiano nei manuali polacchi di storia dell’educazione
Authors: Wnęk Jan 
Published: July 2018

This paper describes the popularization of the Italian pedagogical thought in Polish textbooks about the history of education in general. It has shown that the authors of the textbooks gave a lot of information about the Italian school system and education and presented profiles of outstanding Italian educationalists, e.g. St John Bosco or Maria Montessori. This paper indicates that in the past centuries Poles were open to Italian intellectual currents, academic trips to the Italian Peninsula, and education at local universities. Polish textbooks about the history of education were popular (in the 20th c.) and still are an important source of knowledge about the history of Italian education. For the purposes of this paper, the contents of the most representative and popular textbooks have been analysed.
Mary is a Model of Faith and Moral Life for the Contemporary Disciples of Christ
Authors: Kluz Marek 
Published: July 2018

Observing the transformations taking place in the world, it is important to note the need for continuous reference in various areas of human life to Mary, whose example is always relevant. Therefore, the purpose of this article is to present Mary as a model of faith and moral life for the contemporary disciples of Christ. Mary – with her example – teaches one how to be a disciple of Christ in an authentic way, not superficial one. She is an example of understanding the Christian life as a commitment. Looking to Mary as an example, the individual learns to obey God in the path of faith and finds the values that lead him or her through the paths of the Christian moral life. Life permeated with the Marian spirit becomes an inspiration for the contemporary disciples of Christ to grow in faith, to do good and radically reject everything which is in contrary to the Christian ideal.
