Customer reviews online and rating in this study are expected to affect purchasing decisions of online product on the marketplace. By using analytical tools AMOS 21, we found that customer reviews online has a positive and significant effect on the customer perception. Rating is also has positive and significant effect on the customer perception. The results of this study also revealed that the customer perception has positive and significant effect on purchasing decisions.
Importance of maintaining body weight for prevention of distant metastasis of nasopharyngeal carcinoma: An alternative workflow for cancer-risk assessment

Purpose: To design an alternative workflow for cancer-risk assessment to predict distant metastasis (DM) of nasopharyngeal carcinoma (NPC). Methods: We enrolled 234 patients with non-disseminated NPC and a family history of cancer who underwent intensity-modulated radiotherapy and concurrent chemo-radiotherapy with/without induction chemotherapy in our primary cohort. We conducted univariate and multivariate analyses of the associated prognostic factors, built a nomogram model for distant-metastasis-free survival (DMFS), and confirmed the prognostic value of weight-loss ratio (WTratio). The secondary cohort included 97 patients with available pre-DNA levels who were treated at our cancer center. We performed internal validation with the primary cohort and external validation with the secondary cohort, and compared the new DMFS model with the current 7th TNM staging system. Results: In the primary cohort, 95.9% patients experienced weight loss. The N group (N2-3 vs. N0-1, P = 0.037) and pre-DNA level (P = 0.02) were independent prognostic factors for DMFS in NPC patients. Smoking (P = 0.051) and WTratio (P = 0.052) showed a significant trend for DMFS. WTratio was an independent prognostic factor for DMFS (P = 0.03). Smoking, WTratio, N group, and pre-DNA level were merged to build a risk-score model for DMFS using a nomogram, which could predict survival after internal and external validation. Conclusions: Maintaining body weight during treatment is essential to prevent DM of NPC. Compared with the current 7th TNM staging system, the new DMFS model might better predict DM of NPC. The alternative workflow designed could be applied for prognostic analysis of other cancers.
Price discrimination and market power in the international fertiliser market: empirical evidence for exports from Russia

Purpose. In 2012, Russia became the world’s second-largest exporter increasing its potash exports from 1996 to 2012 more than two times. The top five countries control more than 50 % of the world’s exports, particularly 53.4 % (38.0 mln MT) for nitrogen, 73.4 % (3.5 mln MT) for phosphate and 90.8 % (35.5 mln MT) for potash. The objective of this study is to analyse the market structure and market concentration of the Russian export company in the international fertiliser market, and to develop hypotheses about the oligopolistic market behaviour. The empirical part of this study tests the hypotheses by employing econometric models to provide evidence for market power and price discrimination in the international fertiliser market. Methodology / approach. The empirical analysis in this study relies on the theoretical framework of pricing-to-market (PTM) pioneered by Krugman (1986, 1987). Following Krugman’s groundbreaking approach, Knetter (1989) developed an empirical model testing the PTM hypothesis. The major advantages of the Knetter’s model are that the pricing behaviour of the export country towards the import countries can be estimated with public statistical data for the export statistics of the export country and bilateral exchange rates between the currencies of the export and import countries. Results. This study presents empirical evidence for the behaviour of Russian exporters in the international fertiliser market. The estimation results indicate that market power in the export market for nitrogen fertilisers is exercised by Russian exporters in more than two-thirds of the destination countries and in the export market for potash fertilisers in eight out of nine countries. The exercising market power in the export market for potash fertilisers is much more pronounced than in the nitrogen fertiliser export market. Originality / scientific novelty. Primarily against the background of increased market concentration by the companies in the fertiliser markets and regarding the aforementioned cartel dispute, this study constitutes a first attempt to close the research gap in the empirical literature and to promote empirical research on the market behaviour of export companies in the international markets for nitrogen and potash fertilisers. Practical value / implications. This study uses econometric techniques to examine the collapse of the potash cartel on the use of price discrimination and the exercising of market power in the international fertiliser market by Russia. The descriptive analysis shows that Russia plays an important role in the export of nitrogen and potash on the world market and many importing destinations. Often Russia in addition to the high market share also has no or few competitors in the various destinations, which supports speculation of exercising market power.
Compression and the wheel of fortune

Data compression techniques hinged on the notion of a motif are presented, interpreted here as a string of intermittently solid and wild characters that recurs more or less frequently in an input sequence or family of sequences. Correspondingly, motif discovery techniques and tools have been devised. This task is made difficult by the circumstance that the number of motifs identifiable in general in a sequence can be exponential in the size of that sequence. A significant gain in the direction of reducing the number of motifs is achieved through the introduction of irredundant motifs, which in intuitive terms are a combination of other motif occurrences. The number of abundant motifs in a sequence is at worst linear in the sequence. It is shown that irredundant motifs can be usefully exploited in lossy compression methods based on textual substitution and suitable for signals as well as text. Preliminary experiments with these fungible strategies at the crossroads of lossless and lossy data compression show performances that improve over popular methods by more than 20% in lossy and 10% in lossless implementations.
An Efficient Approach to Hide Compressed Voice Data in Arabic Text using Kashida and "La"

In this research, we propose a new approach to increase the capacity and enhance the reliability of hiding voice data in Arabic text. Using Kashida to hide bits in Arabic text is one of the most promising approaches in steganography. Unfortunately, ignoring the original Kashida in the cover text may affect the results significantly and produce inaccurate results in the extraction process. In this study, we propose tremendous improvements to the Kashida method by considering original Kashida(-) in the cover text, error-detection using Cyclic Redundancy Check (CRC) and hiding bit using the "La" word. Moreover, hiding voice files within Arabic text is considered. The proposed approach is compared with the most related approaches in terms of capacity, security and reliability. Not only are the findings of the paper promising, they also overcome the limitations of other approaches.
Validity of pneumonia severity index and CURB-65 severity scoring systems in community acquired pneumonia in an Indian setting.

BACKGROUND Little information is available from India regarding prognostic factors in patients with community acquired pneumonia (CAP). METHODS Hospital-based prospective study to test the validity of pneumonia severity index (PSI) and the confusion, urea, respiratory rate, blood pressure, age over 65 years (CURB-65) risk scoring systems in patients with CAP (n=150). RESULTS Although both CURB-65 class > or = III and PSI class > or = IV were 100% sensitive in predicting death, CURB-65 class > or = III had a higher specificity (74.6%) than PSI class > or = IV (52.2%) when used to predict death. In both PSI and CURB-65 risk scoring systems, mortality rate, need for intensive care unit (ICU) admission, prolonged need for intravenous (I.V.) antibiotics, prolonged duration of hospital stay and need for admission to ICU increased progressively with increasing scores. The PSI class > or = IV was more sensitive in predicting ICU admission than CURB-65. The duration of hospital stay was found to have a weak but significant correlation with PSI and CURB-65 criteria. Defervescence time also had a very weak but significant correlation with PSI and CURB-65 criteria. Duration of I.V. antibiotics had a moderately strong correlation with CURB-65 criteria but a weak correlation with PSI criteria. CONCLUSIONS Both PSI and CURB-65 were found to have equal sensitivity to predict death from CAP. Specificity of CURB-65 was higher than that of PSI. However, PSI was more sensitive in predicting ICU admission than CURB-65.
Efficient Proximal Mapping of the 1-path-norm of Shallow Networks

We demonstrate two new important properties of the 1-path-norm of shallow neural networks. First, despite its non-smoothness and non-convexity it allows a closed form proximal operator which can be efficiently computed, allowing the use of stochastic proximal-gradient-type methods for regularized empirical risk minimization. Second, when the activation functions is differentiable, it provides an upper bound on the Lipschitz constant of the network. Such bound is tighter than the trivial layer-wise product of Lipschitz constants, motivating its use for training networks robust to adversarial perturbations. In practical experiments we illustrate the advantages of using the proximal mapping and we compare the robustness-accuracy trade-off induced by the 1-path-norm, L1-norm and layer-wise constraints on the Lipschitz constant (Parseval networks).
Unsolved issues of mixed treatment comparison meta‐analysis: network size and inconsistency

Indirect comparisons and mixed treatment comparison (MTC) meta‐analyses are increasingly used in medical research. These methods allow a simultaneous analysis of all relevant interventions in a connected network even if direct evidence regarding two interventions is missing. The framework of MTC meta‐analysis provides a flexible approach for complex networks. However, this method has yet some unsolved problems, in particular the choice of the network size and the assessment of inconsistency. In this paper, we describe the practical application of MTC meta‐analysis by using a data set on antidepressants. We focus on the impact of the size of the chosen network and the assumption of consistency. A larger network is based on more evidence but may show inconsistencies, whereas a smaller network contains less evidence but may show no clear inconsistencies. A choice is required which network should be used in practice. In summary, MTC meta‐analysis represents a promising approach; however, clear application standards are still lacking. Especially, standards for the identification of inconsistency and the way to deal with potential inconsistency are required. Copyright © 2012 John Wiley & Sons, Ltd.
The Anatomic Reconstruction of Acromioclavicular Joint Dislocations Using 2 TightRope Devices

Background For the reconstruction of acromioclavicular (AC) joint separation, several operative procedures have been described; however, the anatomic reconstruction of both coracoclavicular ligaments has rarely been reported. Purpose The aim of this biomechanical study is to describe a new procedure for anatomic reconstruction of the AC joint. Study Design Controlled laboratory study. Materials and Methods Forty fresh-frozen cadaveric shoulders were tested. Cyclic loading and a load-to-failure protocol was performed in vertical (native, n = 10; reconstructed, n = 10) and anterior directions (native, n = 10; reconstructed, n = 10) on 20 AC joints and repeated after anatomic reconstruction. Reconstruction of conoid and trapezoid ligaments was achieved by 2 TightRope devices (Arthrex, Naples, Florida). Dynamic, cyclic, and static loading until failure in vertical (n = 5) and horizontal (n = 5) directions were tested in native as well as reconstructed joints in a standardized setting. Results The native coracoclavicular ligaments in static load for vertical force measured 598 N (range, 409–687), elongation 10 mm (range, 6–14), and stiffness 99 N/mm (range, 67–130); static load for anterior force was 338 N (range, 186–561), elongation 4 mm (range, 3–7), and stiffness 140 N/mm (range, 70–210). The mean maximum static load until failure in reconstruction for vertical force was 982 N (range, 584–1330) (P = .001), elongation 4 mm (range, 3–6) (P < .001), and stiffness 80 N/mm (range, 66.6–105) (P = .091); and for anterior static force 627 N (range, 364–973) (P < .001), elongation 6.5 mm (range, 4–10) (P = .023), and stiffness 78 N/mm (range, 46–120) (P = .009). During dynamic testing of the native coracoclavicular ligaments, the mean amount of repetitions (100 repetitions per stage, stage 0–100 N, 100–200 N, 200–300 N, etc, and a frequency of 1.5 Hz) in native vertical direction was 593 repetitions (range, 426–683) and an average of 552 N (range, 452–683) load until failure. In vertical reconstructed testing, there were 742 repetitions (range, 488–893) (P = .222; with a load until failure of 768 N (range, 486–900) (P = .095). In the anterior direction load, the native ligament failed after an average of 365 repetitions (range, 330–475) and an average load of 360 N (range, 307–411), while reconstructed joints ended in 549 repetitions (range, 498–566) (P = .008J with a load until failure of 547 N (range, 490–585) (P = .008). In all testing procedures, a preload of 5 N was performed. Conclusion The anatomic reconstruction of the AC joint using TightRope is a stable and functional anatomic reconstruction procedure. The reconstruction technique led to favorable in vitro results with equal or even higher forces than native ligaments. Clinical Relevance Through anatomic repair, stable function of the AC joint can be achieved in an anatomic manner.
“Nudging” Islamic Banks’ customers: Using behavioral insights to boost savings

Islamic banks are important players in Islamic capital markets. Consequently, improving savings both from a balance and duration standpoints should have a positive effect on Islamic capital markets, which face depth and broadness issues. Given that saving behavior is subject to several biases at the individual investor level, this paper surveys the use of behavioral insights or “nudges” as effective tools to increase savings in conventional finance. We readapt these insights to the context of Islamic banks' consumers and make suggestions on how to apply "nudging" to increase saving in Islamic banking
Establishment of a tet-on gene expression system in glucose-responsive and -unresponsive MIN6 cells.

The tetracycline (or doxycycline)-inducible gene expression (Tet-On) system developed by Gossen and Bujard (1) is useful for controlling the expression of targeted genes and for determining the roles of the gene products in cellular functions. The Tet-On system has recently been applied to the rat insulinoma cell line INS-1 to study the roles of wild-type and mutant genes in insulin secretion (2,3). We have recently established two cell lines, MIN6-m9, and MIN6-m14, derived from the mouse insulinoma-derived cell line MIN6. MIN6-m9 and MIN6-m14 cells are glucose-responsive and glucose-unresponsive, respectively. To study the roles of newly identified genes in pancreatic � -cell functions, we have established a Tet-On system in these MIN6 sublines.
Concentrations of eNOS, VEGF, ACE and PlGF in maternal blood as predictors of impaired fetal growth in pregnancy complicated by gestational hypertension/preeclampsia

Objectives: To investigate into an association between circulating levels of vascular factors (VF: ACE, eNOS, PlGF and VEGF) and impaired fetal growth measured as a small for gestational age newborn (SGA) in women with gestational hypertension/preeclampsia. Methods: A prospective observational trial in 46 patients in singleton pregnancies. Concentrations of VF were compared between participants who delivered SGA versus non-SGA newborns. Results: only low levels of ACE were associated with significantly increased risk for SGA (for a cut-off value, LR: 1.4–3.6). Conclusions: Circulating levels of VF are not sufficient predictors of SGA in pregnancies complicated by gestational hypertension/preeclampsia.
Morbidity following intravenous injections

Tt is common anaesthetic practice to give an intravenous injection to induce unconsciousness because it is usually more pleasant for the patient to go to sleep with an injected than with an inhaled anaesthetic. It is, however, important to remember that intravenous injection may be painful and that it is sometimes followed by haematomata, scarring or by pain which may last for months. ’ This study was designed to analyse these troubles and to see whether they are more likely to occur when the injection is made into the back of the hand or the antecubital fossa, and whether the use of indwelling needles increases or decreases their incidence. In addition, an attempt was made to identify the groups of patients most likely to complain about painful injections.
Evolutionary aspects of autotrophy.

The commencement of the writing of this review coincided with the first microbiological experiments conducted on the surface of Mars, within the Viking spacecraft. Thus, on the one hand scientists speculate on the sequence of events which led to the development of life on this planet a few thousand million years ago, while on the other hand, a man-made scoop measures out Martian soil into culture vessels in order to see whether life has ever developed or is likely to develop on another planet of the solar system more than 35 million miles away. The fascination of this arching of the intellect is
Childhood infection and endothelial dysfunction: a potential link in atherosclerosis?

The prodromal stage of atherosclerotic lesions (known as lipidotic fatty streak accumulation) is already formed during human fetal development.1 Fatty streaks containing characteristic accumulations of lipids, lipid peroxidation products, and macrophages occur in the aorta of premature fetuses. Intimal thickening is also observed in fetal coronary arteries.2,3 During infancy, fatty streaks become increasingly prevalent, and some of them progress to advanced stages of atherosclerotic lesions.4–7 Once initiated, the progression of atherosclerosis is influenced by classic risk factors that promote vascular inflammation and plaque rupture. The observation that maternal hypercholesterolemia is associated with greatly enhanced fatty streak formation in fetal arteries1 indicates that hypercholesterolemia may play a pathogenic role in early fetal atherosclerotic lesions. Maternal hypercholesterolemia is also able to influence fetal sterol metabolism during pregnancy in animal models.8,9 Consistently, direct evidence for a causal role of maternal hypercholesterolemia and the involvement of oxidative stress has been obtained in a rabbit model10,11 and in LDL receptor–deficient mice.12 From a molecular standpoint, many signaling pathways are affected by increased oxidation of LDL or the intracellular formation of reactive oxygen species, and this phenomenon can be exacerbated by concomitant hypercholesterolemia.13 Interestingly, deletion of the p66 shc longevity gene reduces systemic and tissue oxidative stress, vascular cell apoptosis, and early atherogenesis in mice fed a very highly hypercholesterolemic diet.14 Finally, growing evidence in the literature suggests that vascular damage occurs early and is mediated by …
The effect of smartphone use on trends in European adolescents’ excessive Internet use

ABSTRACT Despite growing public health concerns data on excessive Internet use (EIU) allowing for comparison between countries and over time are scarce. Our study is the first attempt to evaluate the changes and the impact of mobile access on EIU in Europe. It is based on data from 2 surveys of adolescents implemented in 2010 and 2013 in 7 European countries that used identical methodology; a total of 7663 adolescents were recruited by random stratified sampling. The levels of EIU were compared and a regression model was used to assess the impact of smart devices, the number of activities performed online, and the specific online applications. A small but significant increase of EIU levels was observed in Belgium, Denmark, Romania, the UK, and overall. Although smartphone use is a positive predictor of EIU, it is moderated by the increasing number of activities performed online. The increase in levels of EIU is also associated with the daily use of online games and social networking sites.
p-Refinement for large-domain waveguide structures analyzed by FEM-MM technique

Coupling of a mode matching (MM) method with a higher order large-domain finite element method (FEM) is presented in analysis of three-dimensional waveguide structures with discontinuities. The new FEM-MM technique enables very effective higher order hexahedral meshes constructed from a very small number of large curved conformal finite elements (large domains) and p-refined high-order field expansions. This results in solutions with minimal total numbers of unknowns.
[Experimental study of anti-vascular endothelial growth factor hairpin ribozyme gene inhibiting growth of xenografted tumor of ovarian cancer cells].

OBJECTIVE We propose to block the autocrine and (or) paracrine pathway of vascular endothelial growth factor (VEGF) in ovarian cancer by using anti-VEGF hairpin ribozyme gene to see whether the growth of tumor cells could be inhibited and to further exploit its mechanisms. METHODS Anti-VEGF hairpin ribozyme gene eukaryotic expression vector was introduced into ovarian cancer cells SKOV(3) by using lipofectin mediation and positive clones were screened by genticin (G418); ribozyme (RZ) expression was confirmed by RNA dot blot; the VEGF expression of SKOV(3) cells before or after transfection were detected by reverse transcription polymerase chain reaction (RT-PCR) method, transmission electron microscopy demonstrated the morphologic changes of ribozyme-generating SKOV(3) cells; the growth of transfected cells in nude mice were detected. RESULTS VEGF expression was decreased distinctly in SKOV(3) cells transfected by RZ (SKOV(3)-RZ) cells. Apoptosis cells were observed; the formation rate and growth speed of xenografted tumor slowed down. CONCLUSIONS Anti-VEGF hairpin ribozyme gene can inhibit the expression of VEGF mRNA and VEGF in SKOV(3) cells. The growth of xenografted tumor in nude mice was inhibited by reduced angiogenesis. This provides an experimental basis for curing human ovarian cancer with antiangiogenesis method.
