The interaction between standards development and economic growth of China
Authors: Zhang Hao , Jiang Jiadong , Zheng Liwei , Li Xiangzhen 
Published: November 2019

AbstractChina has been participating in the international standards activities since the reform and opening up period. China’s standards action has not only brought about significant changes in the way of international trade, but also changed the connotation and manifestation of economic growth, which has further affected China’s position in the world standards development. On the basis of qualitative analysis of the interaction between standards development and economic growth, this paper quantitatively analyzes the degree of interaction between them. The results indicate that the higher standards in a country, the stronger its economic strength and the higher its position in world standards development. This conclusion is helpful for the government, industry authorities, and enterprises to pay more attention to standards in quality management and improve the standards level.
Spatio-temporal silhouette sequence reconstruction for gait recognition against occlusion

Published: November 2019

Abstract
Gait-based features provide the potential for a subject to be recognized even from a low-resolution image sequence, and they can be captured at a distance without the subject’s cooperation. Person recognition using gait-based features (gait recognition) is a promising real-life application. However, several body parts of the subjects are often occluded because of beams, pillars, cars and trees, or another walking person. Therefore, gait-based features are not applicable to approaches that require an unoccluded gait image sequence. Occlusion handling is a challenging but important issue for gait recognition. In this paper, we propose silhouette sequence reconstruction from an occluded sequence (sVideo) based on a conditional deep generative adversarial network (GAN). From the reconstructed sequence, we estimate the gait cycle and extract the gait features from a one gait cycle image sequence. To regularize the training of the proposed generative network, we use adversarial loss based on triplet hinge loss incorporating Wasserstein GAN (WGAN-hinge). To the best of our knowledge, WGAN-hinge is the first adversarial loss that supervises the generator network during training by incorporating pairwise similarity ranking information. The proposed approach was evaluated on multiple challenging occlusion patterns. The experimental results demonstrate that the proposed approach outperforms the existing state-of-the-art benchmarks.
Designing Pricing Strategy for Operational and Technological Transformation
Authors: Kumar Vineet , Sun Yacheng 
Published: November 2019

We examine how operational or technological transformation impacts consumer value, as well as the effectiveness of a firm’s pricing strategies. We develop a model of multidimensional screening featuring forward-looking consumers who make short-run consumption and long-run purchase decisions. Using a detailed panel of consumer data from a rental-by-mail firm, we estimate consumer utility for current consumption, obtaining heterogeneous preferences for bunching and smoothing consumption. Using counterfactual analysis, we evaluate the impact of improving service time. We find that the firm with improved service time might create more value for all consumers, but its profits and even revenues could diminish because value extraction becomes more difficult. We find a novel mechanism that causes this effect, which is driven by increased consumer heterogeneity in the valuation for each product and reduced differentiation across products. This result persists even when the firm can reoptimize its price levels based on the service time. We find that a change in the pricing strategy might be required for the firm to obtain higher revenue with improved service time. This paper was accepted by Matthew Shum, marketing.

Los niños, por su parte, dieron muestras de haber evolucionado en la construcción de sus modelos explicativos en torno al fenómeno de caída libre y de equilibrio, abordando conceptos como masa, peso, volumen, equilibrio, fuerza de fricción y empuje.
Effective segmentation and classification of tumor on liver MRI and CT images using multi-kernel K-means clustering
Authors: Krishan Abhay , Mittal Deepti 
Published: November 2019

Abstract
Our proposed research technique intends to provide an effective liver magnetic resonance imaging (MRI) and computed tomography (CT) scan image classification which would play a significant role in medical dataset especially in feature selection and classification. There are a number of existing research works classifying the liver tumor disease. Early detection of liver tumor will help the patients to get cured rapidly. Our proposed research focuses on the classification of medical images with respect to the classification technique artificial neural network (ANN) to classify an image as normal or abnormal. In the pre-processing step, the input image is selected from the database and adaptive median filtering is used for noise removal. For better enhancement, histogram equalization (HE) is done in the noise-removed images. In the pre-processed images, the texture feature such as gray-level co-occurrence matrix (GLCM) and statistical features are extracted. From the extensive feature set, optimal features are selected using the optimal kernel K-means (OKK-means) clustering algorithm along with the oppositional firefly algorithm (OFA). The proposed method obtained 97.5% accuracy in the classification when compared to the existing method.
Clouded reality: News representations of culturally close and distant ethnic outgroups
Authors: Kroon Anne C. , Trilling Damian , Meer Toni G. L. A. van der , Jonkman Jeroen G. F. 
Published: November 2019

Abstract
The current study explores how the cultural distance of ethnic outgroups relative to the ethnic ingroup is related to stereotypical news representations. It does so by drawing on a sample of more than three million Dutch newspaper articles and uses advanced methods of automated content analysis, namely word embeddings. The results show that distant ethnic outgroup members (i. e., Moroccans) are associated with negative characteristics and issues, while this is not the case for close ethnic outgroup members (i. e., Belgians). The current study demonstrates the usefulness of word embeddings as a tool to study subtle aspects of ethnic bias in mass-mediated content.

CircRNA-UCK2 increased TET1 inhibits proliferation and invasion of prostate cancer cells via sponge miRNA-767-5p
Authors: Xiang Zhendong , Xu Chengdang , Wu Gang , Liu Bo , Wu Denglong 
Published: November 2019

Abstract
A majority of the patients with advanced prostate cancer initially respond to androgen deprivation therapy and enzalutamide therapy, but eventually enter the castration-resistant prostate cancer (CRPC) phase. Some studies have shown that the activation of other signalling pathways in CRPC cells replaces the function of the androgen receptor, as well as promotes cell metastasis and progression. However, the mechanisms underlying this side effect remain unclear. The present study aims to explore the continued progression of cells after enzalutamide resistance. Low expression of circRNA-UCK2 (circUCK2) was detected in enzalutamide-resistant (EnzR) cells. Moreover, miR-767-5p was found to be resistant to EnzR cells when the level of circUCK2 is increased. The decrease in free miR-767-5p increases the expression of TET1 protein through the post-transcriptional regulation of mRNA, thereby inhibiting cell invasion and proliferation. Knocking down circUCK2 in enzalutamide-sensitive cells reduces the concentration of TET1, thereby increasing cell invasion and proliferation. A preclinical study using in vivo mouse models also showed that a high expression of circUCK2 inhibited the EnzR cell growth. Thus, this study might aid in developing a novel therapy to better suppress the CRPC progression.
Entwaffnung, Demobilisierung und Reintegration: Ein unzureichend genutztes Instrument der Diplomatie im Jemen
Authors: Jachnik Clive 
Published: November 2019

Zusammenfassung
Entwaffnung, Demobilisierung und Reintegration (DD&R) ist der Prozess der Abgabe von Waffen durch Mitglieder bewaffneter Gruppen, der Herausnahme der Ex-Kombattanten aus ihren Gruppen und der Unterstützung bei ihrer Rückkehr in ein normales Leben. DD&R kann in Gemeinschaften, die von Konflikten betroffen sind, einen erheblichen Beitrag zur Wiederherstellung des Friedens leisten. Im Lauf der Zeit hat das UN-DD&R sein Aktivitätsfeld erweitert; zu seinen strategischen Prioritäten gehört mittlerweile auch das Bemühen, Verzahnungen mit politischen Prozessen sicherzustellen. Im Hinblick auf die Situation im Jemen hat das UN Yemen DD&R Forum allerding die Breite der UN-DD&R-Programme völlig missverstanden und sich sogar dafür ausgesprochen, vor der Unterzeichnung eines Friedensabkommens sämtliche DD&R-Initiativen im Jemen einzustellen. Überdies hat das Forum es unterlassen, andere UN-Organisationen oder wichtige Stakeholder für die Möglichkeiten von Prä-DD&R oder Kommunaler Gewaltreduzierung (CVR) zu sensibilisieren. Dies hat dazu geführt, dass die Planungen sowohl für DD&R- als auch für Stabilisierungsbemühungen im Jemen unzureichend gewesen sind bzw. praktisch gar nicht erfolgten.

Published: November 2019

Abstract

Background and aims
Previous systematic reviews have considered that providing patient information is ineffective for patients with whiplash-associated disorders (WAD), with the exception of interventional educational videos. The aim of this randomised controlled clinical trial was to determine if use of an educational video as an intervention in the acute stage after a whiplash injury might improve self-reported recovery at 6 months after the injury.

Methods
In total, 289 consecutive patients with a whiplash injury following a motor vehicle collision were randomised to an intervention group (educational video) or to a control group (written information sheet). The video focused on information about pain mechanisms, deep flexor physiotherapy and reassurance. Emailed questionnaires were used to collect baseline data within 2 weeks after the accident and then to collect outcome data at 6 months post-injury. Non-responders were followed up with a brief telephone interview regarding the outcome. The primary outcome measure was self-reported recovery (yes/no) at 6 months post-injury. The secondary outcomes measures were pain level according to a numeric rating scale (NRS) and the whiplash disability questionnaire (WDQ) score at the same time point.

Results
The response rate for the baseline questionnaire was 70% (203/289). The follow-up rate was 97% (196/203). The non-recovery rates were similar between the intervention group, at 37.9% (39/103), and the control group, at 33.3% (31/93) (p = 0.55). No differences between the groups were noted in pain levels, NRS scores (1.9 vs. 2.2, p = 0.35) or the mean WDQ scores (17.5 vs. 21.2, p = 0.42).

Conclusions
The intervention with the educational video used in this study had no effect on the non-recovery rate when compared to a basic written information sheet.

Implications
The results of this trial add knowledge to the area of patient education for patients with acute WAD. Further studies are needed before the current recommendations for patient information are modified.

<p>The growth and development of sago palm naturally interact with the organism such as insects. The symptoms of damage to the plant canopy sago indicate a relationship between insects and plants. This study aims to identify phytophagous insects, symptoms of damage and attack rates on sago plants. The study was conducted in the village of Rutong and Tulehu in Maluku, starting in June until September 2016. There are 10 plants/sago clump in each observations in each location determined by purposive sampling. Each sago clump in the growth phase (seedlings, tillers, a trunk stage, and stems / trees), observed symptoms of damage to leaflets and leaf midribs. The results showed four symptoms of attack on the sago canopy with an average intensity of mild attacks. The highest incidence of attack was 37.5% in the phase of a trunk stage with the symptoms of cutout attacks on the leaves. Then seven species phytophag insects were obtained which were associated with sago canopy.

The objective of this study was to determine the major weeds and their controls for soybean grown after rice in lowland. The study was conducted in two stages. The first stage was a survey to observe the major weeds in soybean crops grown after rice in the farmers’ fields at three </span>central soybean production areas in Banyuwangi, namely Gambiran, Purwoharjo, and Tegal Dlimo subdistricts. The second stage was a trial conducted in lowland after rice in Genteng Research station, Banyuwangi during the dry season of 2013. The treatments were arranged in a randomized completely block design with three replications. The treatments consisted of: 1) without weed control, 2) weeding twice, 3) preemergence herbicide oxyfluorfen,(4) oxyfluorfen + postemergence 2,4-D dimethylamide, (5) oxyfluorfen + once hand weeding, and (6) once hand weeding. The results indicated that the major weeds were Oryza sativa, Cyperus rotundus, Ageratum sp., Echinochloa crusgalli, and Pilantus niruri consecutively. The weeds were effectively controlled by applying preemergence herbicide oxyfluorfen. This control method reduced the major weeds significantly and showed the same increase in seed yield as in other treatments (one and twice hand weeding) compared to the control treatment (without weeding).The soybean yield obtained from the treatment of without weeding,one hand weeding,and using oxyfluorfen herbicide was 0.60 t/ ha, 1.87 t/ha, and 1.93 t/ha, respectively.The use of oxyfluorfen herbicide is more efficient in terms of labor use than that of hand weeding. </p></div></div></div><p> </p>
