Investigation and Comparison Between Radiation Center and Phase Center for Canonical Antennas

Radiation center, corresponding to minimized angular momentum, and traditional phase center calculations are compared for a set of canonical antenna elements. By using simulation results, the exact phase reference position of the complex-valued far-field pattern is considered exactly known. Influence of user inputs, e.g. angular truncation, on traditional phase center results are investigated. In addition, an analytic method by Muehldorf is used. Adherence of radiation center to traditional phase center behavior is discussed. For the first time the ability of the radiation center algorithm to minimize the phase variations in the main lobe is demonstrated.

Department of Gynecology, Tongde Hospital of Zhejiang Province, Hangzhou, Zhejiang Province, People’s Republic of China Background: LncRNA cancer susceptibility candidate 15 (CASC15) has been demonstrated to act as an oncogene in different cancers; however, its role in ovarian cancer remains elusive. Methods: Quantitative real-time PCR (qRT-PCR) was performed to examine the expression of lncRNA CASC15. Kaplan–Meier survival analysis was performed to evaluate the prognostic significance of lncRNACASC15. CCK-8, soft-agar colony-formation, flow cytometry, transwell migration and invasion assays were used to analyze the biological behavior of lncRNA CASC5 in ovarian cancer. Furthermore, the potential mechanism of lncRNACAC15 was investigated by bioinformatics analysis, luciferase reporter assay, and biotin pull-down assay. Results: In this study, we found that the expression of CASC15 was lower in ovarian cancer tissues and cells by qRT-PCR. In addition, low expression of CASC15 was closely correlated with advanced TNM stage, moderate/poor differentiation, and larger size. Moreover, Kaplan–Meier survival analysis showed that patients with low CASC15 expression level had poorer overall survival and progression-free survival than those with high CASC15 expression. Meanwhile, ROC analysis found that CASC15 had diagnostic values to distinguish tumor tissues from nontumorous tissues. Overexpression of CASC15 prohibited the malignancy of ovarian cancer cells, including proliferation, colony formation, cell cycle, migration, and invasion, and promoted cell apoptosis. In addition, bioinformatics analysis, luciferase reporter assay, and biotin pull-down assay confirmed that CASC15 straightly interacted with miR-221. We also observed that ARID1A was a downstream target of miR-221 and CASC15 subsequently exerted its tumor-suppressive effects by regulating the expression of ARID1A in ovarian cancer cells. Conclusion: Overall, this study firstly elucidated that CASC15 could play a tumor-suppressive role in ovarian cancer by the regulation of CASC15/miR-221/ARID1A axis, which may provide a ponderable prognostic biomarker and promising therapeutic target for treatment of patients with ovarian cancer.
The Effect of Smileys as Motivational Incentives on Children’s Food Choices: A Field Experiment in European Schools

To assess whether school authorities can use smiley stamps as a motivational incentive to promote fruit and vegetable eating among children, we conducted a field experiment in ten primary schools in five European countries using one control and one treatment school per country. The six-week experiment was split into three two-week phases before, during and after the smiley was implemented. During the smiley phase, the children received a smiley stamp for choosing a portion of fruits or vegetables. We find an increase attributed to the smiley stamp on children’s fruit and vegetable choice and consumption, but also waste. Comparing the effects across countries, we observe significant variations in the smiley effect. This study thus demonstrates, in general, that a low-cost, easy-to-implement incentive such as a smiley stamp can be used to motivate school children to increase their fruit and vegetable consumption; the study simultaneously underscores the high relevance of context for the effects of incentives.
Years of life lost due to colorectal cancer in Iran

Aim : The aim of this study was to provide quantitative estimations of the burden of death in term of years of life lost (YLL) due to colorectal cancer (CRC) in Iran and a temporal trend analysis. Background : Colorectal cancer is the third most common cause of cancer-related deaths in the world. YLL is a tool for quantifying the burden of disease according to mortality rates. The aim of this study was to provide quantitative estimations of the burden of death in term of YLL due to colorectal cancer in Iran and a trend analysis. Patients and methods : National death Statistic Reported by the Ministry of Health and Medical Education (MOH&ME) from 1995 to 2003, stratified by age group, sex, and cause of death were included in this analysis. YLL for CRC were expressed as the annual rates per 100,000 of the general population, gender and age group. Results : The general rate of YLL for CRC increased during the years under study from 4.52 to 32.20 per 100,000 of the general population and YLL mortality was higher for older aged males. Conclusion : Our study confirms a temporal trend of increasing YLL due to CRC. Currently there is a low rate of CRC screening in Iran. We recommend that in Iran screening be started, at least in families with a history of CRC, in order to reduce the mortality and burden of CRC in the future.
Procesamiento atencional y recuerdo de palabras emocionales

Three experiments were carried out in order to evaluate the attention paid to words of different emotional value. A dual-task experimental paradigm was employed, registering response times to acoustic tones which were presented during the reading of words. The recall was also evaluated by means of an intentional immediate recall test. The results reveal that neither the emotional valence nor the arousal of words on their own affected the attention paid by participants. Only in the third experiment, in which words belonging to two specific semantic categories (sexual and threatening) were used, did females show significantly higher RTS for threatening words. Nonetheless, significant differences were observed in the immediate subsequent recall for the different types of words in all three experiments. Future studies should take into account: a) the differential status of words and pictures to capture attention, b) the differential influence of valence, as well as arousal, on recall of emotional words, and c) the differential effects of the semantic category on the attention paid to these words by males and females.
VITAMIN E SUPPLEMENT BLOCKS THE RESPONSE OF HDL TO LOVASTATIN THERAPY IN HYPERCHOLESTROLEMIC PATIENTS

HDL can prevent LDL-c oxidation. The low HDL-c State also may benefit clinically from supplemented antioxidant. This study was designed to evaluate the combination therapy of statin and vitamin E in hypercholesterolemic patients. The patients were randomized in a clinical trial aimed to avaluate the effect of vitamin E and/or statin.The life style of patients didn't alter during intervention. The subjects were randomized to two treatment groups A and B: (1) lovastatin 20mg daily at bedtime. (group A); (2) vitamin E 400 iu daily plus lovastatin 20 mg daily (group B). The lipid values of each patients at baseline and after 8 weeks of treatment were compared by paired t test. The mean baseline lipid levels for 60 subjects were as follows: plasma cholesterol, triglyceride, LDL-c and HDL-c 285 ± 68, 268 ± 121, 158 ± 32, 49 ± 11 mg/dl respectively. Serum lipid levels changes in group A (statin only) and in group B (statin and vitamin E) were statistically significant. In comparison of lipid profiles changes between two groups we observed that HDL-c changes in group B were significantly lower than in group A. Vitamin E supplement blocks the respons of HDL-c to lovastatin therapy in hypercholestrolemic patients.
Retrospective Medical Record Research: Reflections of A Unsponsored Researcher

This article is a reflective narrative by the author following the successful completion of a doctoral thesis involving the analysis of primary care data. The aim of the study was to identify patterns in signs and symptoms preceding a clinical diagnosis of Alzheimer’s Disease (AD). Here, we discuss the challenges of conducting research using the patient medical health records as a non-sponsored researcher. The narrative explores the experiences of undertaking practice recruitment, issues that arose around access to data and the requirement for stakeholder commitment, with proposals for other similar projects that attempt to undertake research using patients’ data. The Gibbs reflective cycle was adopted in this narrative. This model encourages a clear description of events, analysis of personal feelings, evaluation of the experience, conclusions as to the options that were considered and actions to take if faced with the same study methods (involving primary care practitioners and/or the review of patient records). It also allows a structured reflection while simultaneously discussing the barriers and facilitators to undertaking a retrospective medical record research. The researcher also proposes some recommendation(s) to overcoming barriers to recruitment in primary care.
Anti‐Aging Effects of Schisandrae chinensis Fructus Extract: Improvement of Insulin Sensitivity and Muscle Function in Aged Mice

Schisandrae chinensis Fructus has a long history of medicinal use as a tonic, a sedative, and an antitussive drug. In this study, we investigated the beneficial effects of Schisandrae chinensis Fructus ethanol extract (SFe) on metabolism in an aged mouse model. Sixteen-month-old C57BL/6J mice were fed with a diet supplemented with SFe for 4 months. Insulin sensitivity was lower at 20 months of age than at 16 months of age; however, the decrease in insulin sensitivity was less in SFe-fed mice. SFe supplementation also appeared to improve glucose tolerance. Body weight gain was lower in SFe-fed mice than in mice fed the control diet. Body fat mass was lower and the lean mass was higher in SFe-fed mice. In addition, the grip strength was enhanced in SFe-fed mice. Histological analysis of the tibialis anterior muscle showed that the size of myofiber and slow-twitch red muscle was increased by SFe supplementation. The expression of proteins related to muscle protein synthesis such as phospho-Erk1 and phospho-S6K1 was increased by SFe supplementation. The mRNA expression of genes related to myogenesis and their encoded proteins such as MyoD, Myf5, MRF4, myogenin, and myosin heavy chain, was increased, whereas that of genes related to muscle degradation, such as atrogin-1, MuRF-1, and myostatin, were decreased relative to control mice. These results suggest that SFe supplementation might have beneficial effects for the improvement of insulin sensitivity and inhibition of muscle loss that occur with aging.
Dependent of Reaction Time on Cu-Doped ZnO Nanostructures Prepared by Chemical Bath Method

Cu-doped ZnO powders were prepared by chemical bath method varying the reaction time at constant synthesis temperature of 80oC and annealed at room temperature. The effect of reaction time on the thermal stability, structure, morphology, optical and luminescence properties of Cu-doped ZnO nanostructures were investigated. The thermogravimetric analysis (TGA) and differential thermogravimetric (DTGA) analysis showed that the best thermal stability is obtained for the sample synthesized for 15 min. The X-ray diffraction (XRD) patterns of the Cu-doped ZnO nanostructures correspond to the various planes of a single hexagonal ZnO phase. The XRD results show that the Zn(OH)2 peaks progressively disappear with increasing the reaction time. An increase in reaction time the XRD peaks changed to the pure hexagonal ZnO structure. The diffraction peaks intensity increasewith an increase in reaction time. The estimated average crystallite sizes calculated using the XRD spectra were found to be42 ± 1 and 50 ± 1 nm for samples synthesized at 5 and 15 minutes respectively. It was observed that the estimated average grain sizes increases with an increase in reaction time. The surface morphology study revealed that the grains are irregular at low reaction time but flower-like at high reaction time. The UV-Vis spectra and the band gap energy showed a red shift with an increase in reaction time. The highest luminescence intensity was found for the Cu-doped samples synthesized at 5 min and further increase in reaction time the was decrease in luminescence intensity. Keywords— Reaction Time, Cu-doped ZnO, thermal stability, surface morphology and Luminescence.
Corporate Debt Maturity and the Financing of Investments in Latin America: Evidence from the 2007-2009 Global Financial Crisis

The financial crisis of 2007-2009 provides a credible exogenous shock to estimate the causal effect of financial contracting on real firm behavior. I analyze the impact of the 2007-2009 global credit supply shock on corporate investment decisions in Latin America. Using data from the Economatica database, I estimate a difference-in-differences model where treated firms are those having a large fraction of their long-term debt maturing at the time of the crisis. The main finding from this analysis is that treated firms cut their investment rates significantly more than other firms whose debt was due well after the crisis. The magnitude of the impact of the global financial crisis on corporate investment in Latin America was firm-specific, depending on each firm’s need for external finance, at the time of the crisis. The evidence in this paper suggests that debt maturity composition is an important variable in understanding how the global credit supply shock of 2007-2009 spread throughout the Latin American corporate sector and highlights the impact of debt maturity structure for corporate financial flexibility.
Particle Sizes of Standard Humic Substances Calculated as Radii of Gyration, Maximum Diameter and Hydrodynamic Radii

Average particle size and particle size distribution of humic substances under solution conditions is useful physicochemical information for investigating the role of humic substances in geochemical processes. In this study, the average particle sizes of standard humic acid (HA) and fulvic acid (FA) samples from the Japanese Humic Substance Society (JHSS) were evaluated by small angle X-ray scattering (SAXS). The scattering intensity in the observed range of scattering angles was higher in the HAs than in the FAs. The distance distribution functions, p(r), involved in the structural characteristics of the particles when dispersed in solution were obtained by a Fourier inverse transform of the scattering intensity. The radii of gyration, RG, calculated from the p(r) were 10.1, 7.3 and 1.4 nm for the Dando HA, Inogashira HA and the two FAs, respectively. Concurrently the hydrodynamic radii (RH) of these standard samples were calculated from Einstein’s equation using already-known molecular weights and intrinsic viscosity for comparison with RG values. The values of RG in the HAs were considerably larger than RH values, probably due to higher sample concentrations in the SAXS measurement. Larger ratios of RG to RH (RG/RH) in the HAs than in the FAs indicate a relatively elongate shape of the HAs as compared to the FAs. This was also confirmed by a ratio of maximum diameter of averaged particles (Dmax) and RG (Dmax/RG) obtained by the SAXS analysis. Smaller particle HAs, which were confirmed in a dilute solution system by high performance size exclusion chromatography (HPSEC), can aggregate in the more concentrated system used for the SAXS measurement. The elongate shape of the larger HA particles may result from hydrophobic interaction between smaller HA particles. In contrast, FAs with low ratios of Dmax/RG and RG/RH were dispersed as stable single small particles in the solution. Larger contents of acidic functional groups in the FA chemical structure allow single FA particles to disperse by electrostatic repulsion. The different dispersion behavior of HAs and FAs in solution can be attributed to their chemical structures.

Finding optimal algal/bacterial inoculation ratio to improve algal biomass growth with wastewater as nutrient source

Algal growth, nutrient removal and settling efficiency were quantified while inoculating sequencing batch reactors with a mixture of microalgae and bacteria (activated sludge). Three algae/bacteria inoculation ratios (5:1, 1:1 and 1:5) as well as pure algal biomass (control) were assessed. Algal biomass production increased with the addition of activated sludge. However, the addition of too much activated sludge can cause disturbance to the Al-Bac biomass growth and algal bacterial processes. All reactors including the control with only algae showed similar settling and nutrient removal efficiencies. Good settling was observed in all reactors with only 5% of total biomass found in supernatant after 1 h of settling. Removal efficiencies of COD, TN and PO4-P in all reactors were 79–82%, 61–65% and 15–37%, respectively, with the lowest phosphorus removal efficiency belonging to 1:5 algae/activated sludge ratio. These results may be due to both long hydraulic (7 days) and solids retention times (up to 30 days). Finally, Al-Bac biomass with 1:1 inoculation ratio showed the best enhancement in terms of biomass growth and algal activities.
Evaluating Preference for and Effectiveness of Telehealth and In-Person Parent Training

Telehealth provides an alternative delivery form of parent training that allows practitioners to disseminate information and feedback at a distance. Telehealth can be as effective as in-person training (Wacker et al., 2013a; Wacker et al., 2013b; Vismara et al., 2009). Despite most telehealth studies indicating high satisfaction, research on patient satisfaction using telehealth has depended mostly on survey instruments, which limits definitive conclusions and may not translate into actual use or selection (Whitten & Love, 2005). The primary purpose of this study was to evaluate a procedure for identifying parent preference of in-person or telehealth training modalities. Secondary purposes were to evaluate and compare correspondence between preference as measured in a choice format and a social validity measure, determine if the procedures can be used to detect differences in acquisition from each modality, and to evaluate effects of parent training on child appropriate and inappropriate behavior. The results support previous research that telehealth can be as effective as in-person training. Participants overall chose telehealth 40.93% of the time. Parent choice on any particular occasion was jointly influenced by other variables. Reported preference results at the end of the study differed from the choice data, which suggests satisfaction may differ from preference or actual use. Future studies could use this method to evaluate preference on a larger scale, or for different kinds of interventions and training modalities.

Objective User Visual Experience Evaluation When Working with Virtual Pixel-Based 3D System and Real Voxel-Based 3D System

Volumetric display shows promising implications for healthcare related applications as an innovative technology that creates real three-dimensional (3D) image by illuminating points in three-dimensional space to generate volumetric images without image separation. We used eccentric photorefractometry to objectively study ocular performance in a practical environment by evaluating near work-induced refraction shift, accommodative microfluctuations, and pupil size for 38 young adults after viewing anaglyph, and volumetric 3D content for prolonged time. The results of our study demonstrate that participants who performed relative depth estimation task on volumetric 3D content were less likely to experience task-induced myopic refraction shift. For both 3D content types, we observed pupil constriction, that is possibly related to visual fatigue. For anaglyph 3D pupil constriction, onset was observed significantly sooner, compared to volumetric 3D. Overall, sustained work with 3D content, and small disparities or the fully eliminated possibility of accommodation-vergence conflict, not only minimizes near work-induced myopic shift, but also provide beneficial accommodation relaxation that was demonstrated in this study as hypermetropic shift for nearly half of participants.
