Submucosal Tunnelling Techniques for Zenker’S Diverticulum: A Systematic Review of Early Outcomes With Pooled Analysis

Supplemental Digital Content is available in the text. In the last decade, flexible endoscopic septotomy has been reported as a well-tolerated and effective treatment for Zenker’s diverticulum. More recently, novel endoscopic submucosal tunneling techniques, namely Zenker-PerOral Endoscopic Myotomy (Z-POEM) and PerOral Endoscopic Septotomy (POES) have been proposed to obtain complete muscular septum exposure and deeper myotomy. The aim of this study is to provide a systematic review with a meta-analysis of the first experiences of third space approaches for Zenker’s diverticulum. Electronic databases (Medline, Scopus, EMBASE) were searched up to October 2020. Studies including patients with symptomatic Zenker’s diverticulum who underwent endoscopic treatment by submucosal tunneling technique were eligible. Procedural, clinical and safety outcomes were assessed by pooling data with a random-effect model to obtain a proportion with a 95% confidence interval. Nine retrospective studies were eligible for inclusion (196 patients). Five studies were performed in the USA, two in Europe and two in Asia. Endoscopic treatment was feasible in 96.9% (I2 = 0%) of patients. The mean procedure duration was 36.4 ± 14.3 minutes. Clinical success was achieved after 93.4% (I2 = 0%) of procedures. The overall adverse events rate was 4.9% (I2 = 0%). No differences between the two approaches (Z-POEM vs POES) have been shown in terms of both efficacy and safety. Submucosal tunneling techniques appear to be feasible for symptomatic Zenker’s diverticulum, with promising results in terms of efficacy and safety outcomes.
PowerPoint as a multimodal retelling tool: students’ slide design, collaboration, and goal-setting

ABSTRACT This study engaged a group of Taiwanese English-as-a-Foreign-Language (EFL) adolescent learners as multimodal composers who used PPT slides to retell important elements of Roald Dahl’s classic novel, Matilda (1988). A total of 158 slides were made by 9 groups of students, and a detailed analysis of the slides revealed that text was often accompanied by visual design and gestural design. The end-of-semester group interviews indicated that 8 out of 9 groups followed a composing in pieces model to finish their group slideshows. Only one group of students met in person to decide together what to put on each slide. Completing the PPT slides and presenting on stage propelled students to set various learning goals, ranging from practicing voice projection to managing time better. A few pedagogical implications and future research directions are offered to conclude the article.
Assessment of Midpalatal Suture Maturation by Skeletal Maturity on Hand Wrist Radiographs

The aim of this retrospective study was to evaluate the correlation between the midpalatal suture maturation and skeletal maturation in growing children aged 7 - 15 years and predict the maturational stages of the midpalatal suture corresponding to skeletal maturity assessed by the skeletal maturation indicators (SMI) and middle phalanx of the third finger (MP3) stages. The group of this retrospective study was consisted of randomly selected 132 male and 135 female in age from 7 - 15 years. The maturation of the midpalatal suture was evaluated by using images from cone-beam computed tomography (CBCT) while the skeletal age was assessed by hand-wrist radiography. CBCT images and hand-wrist radiographs used in this study were obtained from all subjects for orthodontic diagnosis before orthodontic treatment. The maturational stages of the midpalatal suture showed strong correlations with both SMI and MP3 stages. The correlation between the midpalatal suture maturation and SMI (Spearman’s correlation coefficient, ϒS = 0.905, p < 0.05) was slightly greater than that of MP3 stages (ϒS = 0.830, p < 0.05). There was a positive significant correlation between the midpalatal suture maturation and chronological age (ϒS = 0.868,p < 0.05). CBCT for evaluation of the midpalatal suture maturational stages may be unnecessary in every pediatric patients because SMI and MP3 stages were both replaceable useful methods for assessing maturation of the midpalatal suture before orthopedic treatment. In this retrospective study, the diagnostic reliability of the SMI method for estimating midpalatal suture maturation showed better reliability than the MP3 method.
Reexamination of the “uneven route” account of loss aversion

The “ uneven route ” accountpredicts how and why loss aversion appears in human behavior. The account assumes that loss aversion occurs when the routes (the number of transitions of the same possession) for losses are greater than those for gains. The present study manipulated the uneven route account and then reexamined the account by using more harsh and unfavorable experimental conditions. Results of four experiments and a mini meta-analysis consistently showed that the modal choice supporting the uneven route account was robust to variations in the experimental design to the magnitude of payoffs and to the index of measuring loss aversion. That is, loss aversion disappeared in the tax refund versus tax paid scenario compared with the win money versus lose money scenario. These results are expected to enrich the underlying mechanism of loss aversion and attract the interest of fellow researchers to conduct further research to see which account can better explain the loss aversion.
The path to 1Tb/s and beyond datacenter interconnect networks: technologies, components, and subsystems

Modern IoT and 5G applications are driving the growth of Internet traffic and impose stringent requirements to datacenter operators for keeping pace with the increasing bandwidth and low-latency demands. At the same time, datacenters suffer from increasing number of interconnections dictating the deployment of novel architectures and high-radix switches. The ratification of 400 GbE standard is driving the market of optical transceivers nevertheless, a technology upgrade will be soon necessary to meet the tremendous traffic growth. In this paper, we present the development of 800 Gb/s and 1Tb/s optical transceivers migrating to 100 Gbaud per lane and employing wafer-scale bonding of InP membranes and InP-DHBT electronics as well as advanced co-packaging schemes. The InP membrane platform is also exploited for the development of novel ultra-fast optical space switches based on a modular architecture design for scaling to large number of I/O ports.
Practical Approach for Elements within Incorporated Charged Zinc Particles in an Anode Zinc Reactor of a Fabricated Zinc Bromine Battery Cell System (ZnBr2) with Fitting Materials

Batteries with different chemistries and designs encounter various (redox reactions) to store energy through applying charges and discharges rates. Redox flow batteries systems such as zinc bromine batteries cells systems (ZnBr2) can be enclosed with high surface area anode electrodes (reactors) and charged with some amount of added carbon particles for zinc deposition. The electrochemical reactions within a fabricated ZnBr2 battery cell system have been investigated with the coupled inlets and outlets brass fitting materials (15mm and 30mm) of different anode and cathode electrolyte compositions. SEM analysis was explored on some charged particles collected from the anode reactor to identify all the existing elements within the deposited charged zinc particles after several charges. The investigated zinc particles were between 254 microns to 354 microns. The electrolyte composition includes 3 moles of KBr (535.51 grams), 1 mole of KCl (111.89 grams) as the cathode side electrolyte and 3 moles of ZnBr2 (649 grams), 1 mole of ZnCl2 (205 grams), and 1M of KCl (111.826 grams) as the anode electrolyte solution. Originally, this journal paper has discovered the importance of coupling chemically resistance materials to ZnBr2 cells as investigated on the fabricated ZnBr2 cell that was initially converted to a CuZn2 battery cell system and reverted to the ideal ZnBr2 cell system before using an SEM technique to identify separately the present elements.
News Organizations in Colombia Building Consensus through Social Media: A Case of Digital-Native La Silla Vacía

Correlation of different segments of society is a major function of mass media and works by broadening individual’s perspectives and creating common ground between these different segments Little is known about how consensus building works in the networked, digital environment or how it works in Latin America. This study explores the premise on a social media page from a digital-native news organization in Colombia, La Silla Vacía, on the salient issue of Venezuela. It found that the news organization did provide a common ground within its comments, bringing men and women closer together in consensus (rs = 0.76, n = 10, p < 0.05) of the priorities of topics relating to Venezuela (substantive attributes). The study did not find a significant correlation between the topics prioritized by the posts and the topics prioritized by the comments. Audiences focus on Venezuela in relation to the local Colombian presidential election while the news organization focused on the country in relation to refugees and the political transition happening in Venezuela.
Financial Transactions Using FINTECH during the Covid-19 Crisis in Bulgaria

In the context of current crises following COVID-19 and growing global economic uncertainties, the issues regarding financial transactions with FINTECH are increasingly apparent. Consequently, in our opinion, the utilization of FINTECH financial transactions leads to a risk-reduction approach when in contact with other people. Moreover, financial transactions with FINTECH can save up customers’ pecuniary funds. Therefore, during crises, FINTECH applications can be perceived as more competitive than the traditional banking system. All the above have provoked us to conduct research related to the utilization of financial transactions with FINTECH before and after the COVID-19 crisis outbreak. The aim of the article is to present a survey analysis of FINTECH utilization of individual customers before and after the crisis in Bulgaria. The methodology includes a questionnaire survey of 242 individual respondents. For the data processing, we implemented statistical measures and quantitative methods, including two-sample paired t-tests, Levene’s test, and ANOVAs performed through the computer language Python in a web-based interactive computing environment for creating documents, Jupyter Notebook. The findings bring out the main issues related to the implementation of financial transactions with FINTECH under the conditions of the crisis. The findings include the identification of problems related to FINTECH transactions during the COVID-19 crisis in Bulgaria.

Analyzing the root of regional innovation performance in the European territory

Purpose Regional innovation performance is an important indicator for decision-making regarding the implementation of policies intended for regional development. However, regional development policies have led economies to very different competitive positions in matters of innovation. To address these issues, this paper aims to identify the variables that most contribute to the positioning of economies in terms of performance innovation in Europe. Design/methodology/approach The data for this study were collected at the regional innovation scoreboard. This paper uses a quantitative methodology through a multivariate statistical technique (discriminant analysis). Findings The results suggest that specific innovation strategies explain the competitive positioning of economies within each group of countries. It was possible to demonstrate that economies with leader classification show greater comparative robustness in the variables “Small and medium enterprise (SMEs) with product or process innovations,” “SMEs with product or process innovations,” “research and development (R&D) expenditure public sector” and “population with tertiary education,” constituting an effective instrument of innovation policy. Furthermore, it was possible to show that the economies belonging to the modest group do not have a competitive advantage in any of the variables under study, thus providing a reflection opportunity for policymakers at this level. Originality/value The present research identifies which variables are most relevant to the classification considering the regional innovation performance in leader, strong, moderate and modest. Several suggestions were given to companies, policymakers and higher education institutions in the sense that the regions where they operate can improve their innovative performance, which may help to a change in their current classification.
Coalitional Game-Based Cooperative Computation Offloading in MEC for Reusable Tasks

Mobile-edge computing (MEC) has been a promising solution for Internet-of-Things (IoT) applications to obtain latency reduction and energy savings. In view of the loosely coupled application, multiple devices can use the same task code and different input parameters to obtain diverse results. This motivates us to study the cooperation between devices for eliminating the repeated data transmission. Leveraging coalitional game theory, we formalize the cooperative offloading process of a reusable task into a coalitional game to maximize the cost savings. In particular, we first propose an efficient coalitional game-based cooperative offloading (CGCO) algorithm for the single-task model, and then expand it into a CGCO-M algorithm for the multiple-task model with jointly applying a two-stage flow shop scheduling approach, which helps to obtain an optimal task schedule. It is proved that our CGCO and CGCO-M can achieve the Nash-stable solution with convergence guarantee, and CGCO can obtain an optimal solution. The simulations show that CGCO is equal to the optimal exhaustive search (ES) method and CGCO-M is close to ES in terms of cost ratios. Cost ratios of CGCO and CGCO-M are significantly down by 41.08% and 83.70% compared to local executions, respectively. Meanwhile, CGCO-M obtains 41.46% and 89.74% reductions when reuse factors are 0.1 and 1, which means CGCO-M can save more cost with higher reuse density.
The Negative Impact of Uncertainty on R&D Investment: International Evidence

Previous studies have not provided consistent conclusions regarding the impact of uncertainty on research and development (R&D) investment. While most of the previous literature has focused only on one or a small group of countries, this study examines the effect of uncertainty on R&D on the basis of a sample covering 109 countries from 1996 to 2018. The country-level uncertainty is measured using the “World Uncertainty Index”, which has recently been developed by Ahir et al. (2018). By estimating a panel data fixed-effects regression model, it is found that uncertainty has a significantly negative impact on R&D investment at the country-level aggregate scale. We also find that uncertainty depresses the number of R&D personnel and patent applications, although the effect on R&D personnel is not statistically significant. These findings imply that high uncertainty poses a considerable threat to global innovation and technological progress. Heterogeneity analyses across different country groups demonstrate that, although the impact of uncertainty on R&D is not statistically significant in some country groups, its effect is always negative and no positive effect is observed.

Endocrine potential of genistein, resveratrol and 8-prenylnaringenin in gonadal and thyroid axes and related organs

Three phytoestrogens belonging to different structural classes - the isoflavonoid genistein, the stilbene resveratrol and the flavanone 8-prenylnaringenin - were investigated for their endocrine disrupting potential. The substances were tested for their effects on LH and TSH release in pituitary cell culture, and for the response of the HPG- and HPT-axes in ovariectomized rats after a single dose challenge or after long term treatment for three months. Changes in related organs like the reproductive tract, metabolic activity of the liver and bone condition were investigated, too. All three compounds displayed significant and varying changes in the different test systems. Caution is advisable regarding the long term consumption of these naturally occuring compounds as nutritional supplements or herbal preparations at high concentrations without thorough risk-benefit assessment.
Diachronous subduction of the Proto-Tethys Ocean along the northern margin of East Gondwana: Insights from SHRIMP and LA-ICP-MS zircon geochronology in the West Kunlun Orogenic Belt, Northwestern China

ABSTRACT The geological evolution of the Proto-Tethys Ocean remains vague. The Tianshuihai Terrane (TSHT), a subterrane of the West Kunlun, distributed to the south of the Proto-Tethys Ocean during the Early Palaeozoic, records abundant information on the geological evolution of the Proto-Tethys Ocean. In this study, we reported SHRIMP and LA-ICP-MS zircon U–Pb ages, whole-rock major and trace element composition data, and Sr-Nd-Hf isotopes of a suite of monzogranites and the monzonitic-syenitic enclaves in Zankan and syenogranites in Laobing regions of the TSHT, West Kunlun Orogenic Belt. The syenogranites in the Laobing region yielded SHRIMP zircon U-Pb ages of 550.4 ± 6.4 Ma to 547.5 ± 5.3 Ma, which were the earliest age records of subduction-related magmatism in the TSHT during the Late Neoproterozoic-Early Palaeozoic. The host monzogranites in the Zankan area yielded SHRIMP and LA-ICP-MS zircon U-Pb ages of 542.6 ± 8.4 Ma to 540.5 ± 2.8 Ma, which is coeval with the monzonitic-syenitic enclaves ages of 533.8 ± 3.4 Ma to 534.7 ± 3.0 Ma. We speculated that an active margin developed along the TSHT during the Cambrian and the initial subduction of the Proto-Tethys oceanic slab must have occurred prior to the Early Cambrian (>550 Ma). The TSHT and the Southern Kunlun Terrane were distributed between the northern margin of the East Gondwana continent and the Tarim Block. Additionally, the coexistence of two branches of the Proto-Tethys Ocean represented by the Kangxiwa Fault and Kudi Ophiolite Belt during the Early Palaeozoic. Based on the chronological statistics of micro-continental blocks in the northern margin of the East Gondwana continent, subduction of the Proto-Tethys Ocean could be diachronous, initially originating in the northwestern part of the East Gondwana continent, and gradually propagating to the east of the East Gondwana continent.
