Authors: Ogwo Grace N. , Izuchukwu Chinedu , Aremu Kazeem O. , Mewomo Oluwatosin T. 
Published: July 2020

AbstractOur main interest in this article is to introduce and study the class of θ-generalized demimetric mappings in Hadamard spaces. Also, a Halpern-type proximal point algorithm comprising this class of mappings and resolvents of monotone operators is proposed, and we prove that it converges strongly to a fixed point of a θ-generalized demimetric mapping and a common zero of a finite family of monotone operators in a Hadamard space. Furthermore, we apply the obtained results to solve a finite family of convex minimization problems, variational inequality problems and convex feasibility problems in Hadamard spaces.

Published: July 2020

Abstract

Objectives
Using case review to determine whether a patient experienced a delayed diagnosis is challenging. Measurement would be more accurate if case reviewers had access to multi-expert consensus on grading the likelihood of delayed diagnosis. Our objective was to use expert consensus to create a guide for objectively grading the likelihood of delayed diagnosis of appendicitis, new-onset diabetic ketoacidosis (DKA), and sepsis.

Methods
Case vignettes were constructed for each condition. In each vignette, a patient has the condition and had a previous emergency department (ED) visit within 7 days. Condition-specific multi-specialty expert Delphi panels reviewed the case vignettes and graded the likelihood of a delayed diagnosis on a five-point scale. Delayed diagnosis was defined as the condition being present during the previous ED visit. Consensus was defined as ≥75% agreement. In each Delphi round, panelists were given the scores from the previous round and asked to rescore. A case scoring guide was created from the consensus scores.

Results
Eighteen expert panelists participated. Consensus was achieved within three Delphi rounds for all appendicitis and sepsis vignettes. We reached consensus on 23/30 (77%) DKA vignettes. A case review guide was created from the consensus scores.

Conclusions
Multi-specialty expert reviewers can agree on the likelihood of a delayed diagnosis for cases of appendicitis and sepsis, and for most cases of DKA. We created a guide that can be used by researchers and quality improvement specialists to allow for objective case review to determine when delayed diagnoses have occurred for appendicitis, DKA, and sepsis.
Character mediation of plot structure: Toward an embodied model of narrative
Authors: Tu Carmen , Brown Steven 
Published: July 2020

AbstractThe classic view of narrative since the time of Aristotle is that plot structure is prioritized over characters in defining the nature of stories. According to this view, plot is an abstract structure external to the protagonist, and the protagonist’s actions are determined by the thematic goals of the plot. The current analysis calls for a reversal in the prioritization of these elements in creating a story. We present an Embodied Plot model in which character not only drives plot, but embodies plot as well. According to this model, the dramatic arc of plots is attributable to psychological processes occurring in the protagonist’s mind. Plot structure is thus isomorphic with the psychological and problem-solving experience of the protagonist inside the storyworld. We apply this model to a number of fairy tales to demonstrate how the dramatic arc of these stories can be explained in each case by the protagonist’s experientiality.
Enhancing E-Commerce through Blockchain (DLTs): The Regulatory Paradox for Digital Governance
Authors: Guarín Duque Gustavo , Zuluaga Torres Julián David 
Published: July 2020

Abstract
Nowadays, the emergence of Distributed Ledger Technologies (DLTs) and the rapidly developing of the digital economy have the potential to transform the current international regulatory framework. Thus, the current developments of DLTs in e-commerce demand a closer analysis of the implications for global governance and international trade. While the Internet has enhanced the development of new platforms for international trade, DLTs may be instruments to unleash the potential of e-commerce. In this scenario, DLTs could drive, strength and promote e-commerce transactions by diminishing inefficiencies. For instance, it could significantly reduce intermediation costs, facilitating the use and interoperability of smart contracts and single window systems. Indeed, customs operations are very complex and involve different types of intermediaries across borders, creating unnecessary obstacles to trade that could be reduced by the application of DLTs. There is where the regulatory paradox enters into place. The operability of DLTs in e-commerce raises significant regulatory challenges posing new policy questions. For this reason, it is crucial to achieving common understandings among relevant stakeholders to identify a set of principles that guide a country’s regulatory frameworks to facilitate the interoperability of e-commerce. One of the main pieces of the puzzle of proposing a set of principles is how to deal with an appropriate level of intervention from regulators in order to promote trust in international transactions, transparency, efficiency, security and operability among regulatory frameworks. This paper will examine current developments, initiatives, and proposals from different approaches: It will start with an overview of the opportunities that DLTs will create to promote e-commerce. Then, it will explore the current international economic legal framework in light of the application of DLTs in e-commerce, taking into consideration policy recommendations from international institutions and initiatives in some specific jurisdictions. From those views, a set of principles will be identified.
Influence of Al deoxidation on the formation of acicular ferrite in steel containing La

Published: July 2020

AbstractThe formation of acicular ferrite (AF) in steel containing Lanthanum (La) with different contents of Aluminum (Al) has been investigated. It has been found that the amount of AF in La treated steel killed by Al is less than the one with little content of Al. The reasons are as follows: first, Al can change the type of La-containing inclusions and may reduce the effectiveness of La inclusion to induce the nucleation of AF. second, Al can make the cooling rate range of AF nucleation narrower in La treated steel. What’s more, Al can increase the decomposition temperature of austenite, and all these make AF formation difficult. In this study, the content of Al should be controlled to less than 0.018 wt% to obtain a more effective inclusion to induce the formation of AF.
The role of pain, disability and perceived social support in psychological and academic functioning of university students with pain: an observational study
Authors: Serbic Danijela , Zhao Jun , He Jiafan 
Published: July 2020

Abstract

Objectives
University students with pain face unique physical, psychological, social and academic challenges, but research on this is limited. The main aim of this study was to examine how pain, disability and perceived social support relate to psychological and academic outcomes in students with pain. It also compared students with pain and students without pain on measures of depression, anxiety and perceived social support.

Methods
Three hundred and eleven students enrolled in Chinese universities took part in the study, 198 with pain (102 reported acute pain and 96 chronic pain) and 113 without pain. They completed measures of perceived social support, depression, anxiety, pain (intensity, frequency, duration), disability and pain interference with academic functioning.

Results
Students with chronic pain reported higher levels of anxiety and depression and lower levels of perceived social support than students without pain. There were no significant differences between students with acute and chronic pain, and between students with acute pain and those without pain. In the pain sample (containing both acute and chronic pain group), greater interference with academic functioning was predicted by higher levels of pain and disability, and disability also predicted higher levels of depression. After controlling for effects of pain and disability, lower levels of perceived social support predicted higher levels of both anxiety and depression.

Conclusions
These results highlight the role of pain and disability in academic functioning and the role of perceived social support in psychological functioning of students with pain.
Lie symmetry analysis and similarity solutions for the Jimbo – Miwa equation and generalisations
Authors: Halder Amlan K. , Paliathanasis Andronikos , Seshadri Rajeswari , Leach Peter G. L. 
Published: July 2020

Abstract
We study the Jimbo – Miwa equation and two of its extended forms, as proposed by Wazwaz et al., using Lie’s group approach. Interestingly, the travelling – wave solutions for all the three equations are similar. Moreover, we obtain certain new reductions which are completely different for each of the three equations. For example, for one of the extended forms of the Jimbo – Miwa equation, the subsequent reductions leads to a second – order equation with Hypergeometric solutions. In certain reductions, we obtain simpler first – order and linearisable second – order equations, which helps us to construct the analytic solution as a closed – form function. The variation in the nonzero Lie brackets for each of the different forms of the Jimbo – Miwa also presents a different perspective. Finally, singularity analysis is applied in order to determine the integrability of the reduced equations and of the different forms of the Jimbo – Miwa equation.

Published: July 2020

Abstract

Objectives
Blend of seeds and leaves of Picralima nitida herein referred to as West African Durand powder (WDP) was investigated for antinociceptive and anti-inflammatory properties.

Methods
Acute toxic effect of the aqueous extract was evaluated in mice of both sexes. Antinociceptive effect of WDP (100–400 mg/kg) was evaluated in models of acetic acid-induced writhing and thermal nociception on hot plate in mice. Carrageenan-induced paw oedema and air pouch rat models were used to evaluate the anti-inflammatory activity of the extract.

Results
WDP (2,000 mg/kg) showed no toxic effect in mice. WDP at 100, 200 and 400 mg/kg inhibited abdominal writhings by 59.9, 66.0 and 79.0%, respectively. There was a significant increase in reaction time on the hot plate tests in mice treated with WDP (400 mg/kg). The paw oedema was reduced by WDP (100, 200 and 400 mg/kg) 5 h post-carrageeenan. Exudate volume was significantly reduced to 39.8 and 44.8% by 200 and 400 mg/kg WDP, respectively. WDP reduced Leucocytes counts (23.3 and 57.1%, respectively) and neutrophil counts (28.1 and 60.0%, as well as reduced nitrites, malondialdehyde levels and increased glutathione concentrations in the air pouch.

Conclusions
These results suggest that aqueous extract of blend of seeds and leaves of P. nitida possesses antinociceptive and anti-inflammatory properties.
Open modeling and exchange (OMEX) metadata specification version 1.0
Authors: Neal Maxwell L. , Gennari John H. , Waltemath Dagmar , Nickerson David P. , König Matthias 
Published: July 2020

Abstract
A standardized approach to annotating computational biomedical models and their associated files can facilitate model reuse and reproducibility among research groups, enhance search and retrieval of models and data, and enable semantic comparisons between models. Motivated by these potential benefits and guided by consensus across the COmputational Modeling in BIology NEtwork (COMBINE) community, we have developed a specification for encoding annotations in Open Modeling and EXchange (OMEX)-formatted archives. Distributing modeling projects within these archives is a best practice established by COMBINE, and the OMEX metadata specification presented here provides a harmonized, community-driven approach for annotating a variety of standardized model and data representation formats within an archive. The specification primarily includes technical guidelines for encoding archive metadata, so that software tools can more easily utilize and exchange it, thereby spurring broad advancements in model reuse, discovery, and semantic analyses.
The Feminist Strike as Threshold
Authors: Gago Verónica , Gutiérrez Aguilar Raquel 
Published: July 2020

Abstract
This is the transcript of a conversation between Verónica Gago and Raquel Gutiérrez Aguilar. The two authors speak of the “constellation” as a methodology for approaching the process of the “feminist strike.” They discuss a kind of mourning-struggle, a feminist embodying, that by placing itself singularly in all places, becomes irreducible to attempts to limit it via localization/dispersion. The authors ask: what happens with struggles that are able to project themselves on a massive scale without losing their minoritarian vector? It is precisely here that the feminist strike emerges as a threshold, which is to say, as an instance of actuality in the direction of a new political technology of social struggle that also generates a change in the “riot” as a political concept.
Navicula dermochelycola sp. nov., presumably an exclusively epizoic diatom on sea turtles Dermochelys coriacea and Lepidochelys olivacea from French Guiana
Authors: Riaux-Gobin Catherine , Witkowski Andrzej , Kociolek John Patrick , Chevallier Damien 
Published: July 2020

Abstract
Epizoic diatom communities were studied on four turtle species (Chelonia mydas L., Eretmochelys imbricata L., Lepidochelys olivacea Eschscholtz and Dermochelys coriacea Vandelli) from the Eastern Caribbean, the Equatorial West Atlantic and the South Pacific. In the present study, we focused on one taxon of Navicula Bory de Saint-Vincent, described here as a new taxon, which was found on seven individuals of Dermochelys coriacea and one individual of Lepidochelys olivacea in French Guiana. The new Navicula taxon was found neither on Chelonia mydas (83 specimens examined) nor Eretmochelys imbricata (13 specimens examined). Furthermore, the new taxon appears to have a restricted biogeography, as so far it has only been reported from French Guiana. A species of Navicula is reported for the first time as a supposedly exclusive epizoic taxon. Navicula dermochelycola sp. nov. is characterized in detail; its ultrastructure is described and compared with other members of Navicula.

Published: July 2020

AbstractGlobally, weeds have been considered as a major threat and act as a hindrance to crop production, even though the farmers put tremendous efforts to eliminate the weeds to get a better yield. Weeds stayed a steady threat to productivity and manageability of soil and environment, regardless of many years of research and advances in management practices.Parthenium hysterophorusis widely studied all around the world including India as a noxious and an unsafe weed responsible for many health risks in humans and animals. Many experts employed different biological methods using insects, beetle, microorganisms, and certain pathogens, which caused a broad dispersal damage toP. hysterophorus.Biorational weed control is also offered by allelopathy through the production of allelochemicals from the leaf, blossoms, grains, nuts, bud, berry, trunk, and organization of living or decaying plant substance. Allelopathy is the most realistic method to control the weeds as well as different plants. Lately, there has been a proliferation of curiosity to research on plant allelopathy to control weeds in agro-ecosystems. The successful management of this weed can only be achieved by an integrated approach with allelochemicals as a crucial aspect.
Effects of ethanol content on the properties of silicone rubber foam
Authors: Tan Yu , Yao Jin , Zhu He-Ping 
Published: July 2020

Abstract
In this study, silicone rubber foam (SF) was prepared through cross-linking and foaming. The effects of ethanol content on the SF were investigated in terms of the physical properties, static cushioning properties, dynamic thermomechanical properties, and dynamic fatigue properties. The cell structure was characterized using scanning electron microscopy and its relationship with the SF properties was analyzed. With increasing ethanol content, the cell diameter increases gradually and its uniformity deteriorates. Moreover, the density, tensile strength, and elongation at breaking of the SF samples gradually decrease. In addition, with the increase of strain and stress, the cushioning coefficient of SF decreases initially and then increases, and the fatigue times worsens with increasing ethanol content. However, fatigue process has little effect on the cushioning performance of SF, which means the SF can be used as reusable packaging materials and thereby reduce environmental pollution.

Published: July 2020

Abstract
This paper reports volatilization behavior of RuO4 from nitric acid medium using UV–Vis spectroscopy. Ruthenium (III) solution was oxidized to Ru (VIII) using potassium metaperiodate. The absorption peak of RuO4 at 385 nm was used to measure Ru(VIII) concentration in solution. The volatilization kinetics has been studied at different temperature and used to derive rate constant and activation energy values. Almost 82% Ruthenium (VIII) has been volatilized from nitric acid medium at 70 °C whereas it is only 15% at 25 °C. Effect of different parameters like temperature, potassium metaperiodate concentration and nitric acid concentration on volatilization has been studied in depth and reported in this paper.

Authors: Wang Yao , Feng Jianqing , Jin Lihua , Li Chengshan 
Published: July 2020

Abstract
We have grown Cu2O films by different routes including self-oxidation and metal-organic deposition (MOD). The reduction efficiency of Cu2O films on graphene oxide (GO) synthesized by modified Hummer’s method has been studied. Surface morphology and chemical state of as-prepared Cu2O film and GO sheets reduced at different conditions have also been investigated using atomic force microscopy (AFM) and x-ray photoelectron spectroscopy (XPS). Results show that self-oxidation Cu2O film is more effective on phtocatalytic reduction of GO than MOD-Cu2O film. Moreover, reduction effect of self-oxidation Cu2O film to GO is comparable to that of environmental-friendly reducing agent of vitamin C. The present results offer a potentially eco-friendly and low-cost approach for the manufacture of reduced graphene oxide (RGO) by photocatalytic reduction.

Published: July 2020

Abstract
The use of liquid hydrocarbons, such as FCC naphtha, having olefin components makes an adverse impact on our environment. To deal with the problem, one could convert those lethal components, including olefin and paraffin structures, into aromatic compounds under aromatization processes. To this aim, generally zeolite catalysts, especially the ZSM-5 sample, are utilized to facilitate the aromatization processes. According to the general knowledge in this field, such parameters as the metal promoter and the amount of acidity of catalyst affect the performance of zeolite catalysts. In this paper, with the aim of getting acquainted with the conditions to form the desirable products under the best performance of the zeolites, numerous published papers were reviewed.

Accounting for informative sampling in estimation of associations between sexually transmitted infections and hormonal contraceptive methods

Published: July 2020

Abstract
The relationship between hormonal contraceptive method use and sexually transmitted infections is not well understood. Studies that implement routine screening for STIs among different contraceptive users, such as the ASPIRE HIV-1 prevention trial, can be useful for identifying potential risk factors of STIs. However, the complex nature of non-random data can lead to challenges in estimation of associations for potential risk factors. In particular, if screening for the disease is not random (i. e. it is driven by symptoms or other clinical indicators), estimates of association can suffer from bias, often referred to as informative sampling bias. Time-varying predictors and potential stratification variables can further contribute to difficulty in obtaining unbiased estimates. In this paper, we estimate the association between time- varying contraceptive use and Sexually transmitted infections acquisition, in the presence of informative sampling, by extending the work Buzkova (2010). We use a two-step procedure to jointly model the non-random screening process and sexually transmitted infection risk. In the first step, inverse intensity rate ratios (IIRR) weights are estimated. In the second step, a weighted proportional rate model is fit to estimate the IIRR weighted hazard ratio. We apply the method to evaluate the relationship between hormonal contraception and risk of sexually transmitted infections among women participating in a biomedical HIV-1 prevention trial. We compare our results using the proposed weighted method to those generated using conventional approaches that do not account for potential informative sampling bias or do not use the full potential of the data. Using the IIRR weighted approach we found depot medroxyprogesterone acetate users have a significantly decreased hazard of Trichomonas vaginalis acquisition compared to IUD users (hazard ratio: 0.44, 95% CI: (0.25, 0.83)), which is consistent with the literature. We did not find significant increased or decreased hazard of other STIs for hormonal contraceptive users compared to non-hormonal IUD users.
