Published: August 2020

Evaluating road safety is an enduring research topic in Infrastructure and Transportation Engineering. The prediction of crash risk is very important for avoiding other crashes and safeguarding road users. According to this task, awareness of the number of vehicles involved in an accident contributes greatly to safety analysis, hence, it is necessary to predict it. In this study, the main aim is to develop a binary model for predicting the number of vehicles involved in an accident using Neural Networks and the Group Method of Data Handling (GMDH). For this purpose, 775 accident cases were accurately recorded and evaluated from the urban and rural areas of Cosenza in southern Italy and some notable parameters were considered as input data including Daylight, Weekday, Type of accident, Location, Speed limit and Average speed; and the number of vehicles involved in an accident was considered as output. In this study, 581 cases were selected randomly from the dataset to train and the rest were used to test the developed binary model. A confusion matrix and a Receiver Operating Characteristic curve were used to investigate the performance of the proposed model. According to the obtained results, the accuracy values of the prediction model were 83.5% and 85.7% for testing and training, respectively. Finally, it can be concluded that the developed binary model can be applied as a reliable tool for predicting the number of vehicles involved in an accident.
Recent Developments in the Energy Harvesting Systems from Road Infrastructures
Authors: Zabihi Niloufar , Saafi Mohamed
Published: August 2020

The rapid increase in energy demand has resulted in more dependence on fossil fuels, which leads to higher CO2 emissions every year. To overcome this problem, shifting from fossil fuel-based energy resources to renewable and sustainable ones is essential. One of the new research areas developed in this context is the harvesting of energy from urban infrastructures and, in particular, roads. A large amount of energy in the form of heat or kinetic energy is wasted annually on roads. Recovering these local forms of energy as electricity would improve the energy efficiency of cities. In this review paper, recent developments in the field of energy recovery from roads using solar panels, piezoelectric, thermoelectric and electromagnetic harvesters are discussed along with their efficiency, cost and field implementation. Moreover, new advancements in developing compatible energy storage systems are also discussed and summarised. Based on the review, although all of these systems have the potential of recovering at least a part of the wasted energy, only one of them (the electromagnetic converters) is capable of generating a considerable energy level. In addition, based on the evaluation of the maturity of the technologies, and their cost analyses, more studies are required in order to fill the gap between the current state of the technologies and their full operational form.

Authors: Li Yi , Xu Xiuxiu , Song Bo , He Hong
Published: August 2020

Taking Chengdu as an example, based on the destination image theory and employing the content analysis methodology, this paper conducts data mining on the online comment texts of TikTok short food videos, and analyzes the impact of short food videos on the destination image (cognitive image, affective image and conative image). The results show that: (1) in terms of cognitive image, short food videos have increased potential tourists’ attention to the destination image, especially their attention to the flavor characteristics of food in the destination and the local social environment; (2) in terms of affective image, the comments of short food videos are mainly neutral and positive, and the contents about the flavor characteristics of food and the local social environment are more likely to affect the affective image of the destination; and (3) in terms of conative image, the appearance description of food in short food videos brings about an obvious effect of intention, and it also creates the demand to travel together and obtain information. This paper is inspiring for city managers and tourism marketers to use TikTok short videos to establish and disseminate food-based city brands and destination images.
Carbon Footprint of Dwelling Construction in Romania and Spain. A Comparative Analysis with the OERCO2 Tool
Authors: González-Vallejo Patricia , Muntean Radu , Solís-Guzmán Jaime , Marrero Madelyn
Published: August 2020

CO2 emissions due to the construction sector represent 40% of the total, either directly by the use of the building or indirectly by the emissions incorporated in construction materials and products. It is important to achieve a change in this sector to introduce these concepts in a simple way. There are various tools for evaluating emissions in construction projects. In the present work, the OERCO2 tool is used. This work studies housing projects in two European countries belonging to significantly different regions, Spain (Andalusia) and Romania (Bucharest and Transylvania). Although concrete or masonry structures are mainly used in Romania, due to an increased demand for residential buildings in recent years, a new niche has appeared in the construction sector: metallic and mixed (metal–concrete) structures for multi-storied buildings. For these reasons, a comparison between concrete and metallic buildings can be made in order to highlight their environmental impact. Twenty-four projects are selected from Romanian projects with metallic structures, and Spanish projects with concrete structures. They are also differentiated according to the type of foundation used. As expected, buildings with a metallic structure have more economic and environmental impact than reinforced concrete. The materials with greater impact are metal, concrete, cement, and ceramic products. The potential of the tool for the evaluation of various construction solutions, materials, and project phases is demonstrated.
Has China’s Belt and Road Initiative Intensified Bilateral Trade Links between China and the Involved Countries?
Authors: Yu Chunjiao , Zhang Ren , An Lian , Yu Zhixing
Published: August 2020

The Belt and Road Initiative (BRI) is designed to intensify reciprocal trade preferentiality between China and the Belt-Road countries. However, there has been little research empirically examining the policy effects on the trade links between China and the involved countries. This paper attempts to evaluate the BRI effects quantitatively by constructing a new bilateral revealed trade preference index to measure the bilateral trade preferentiality between China and its 114 trading partners. Using a difference in differences model, we show that the trade of China with the Belt-Road countries has become more preferentially linked since the implementation of the BRI. In particular, the bilateral revealed trade preference index between China and the Belt-Road countries has grown approximately 8% faster than has that with the non-Belt-Road countries. We further show that the BRI effects are heterogeneous across different regions. The bilateral trade links have been more significantly intensified in the regions of the China–Indochina Peninsula Economic Corridor, the China–Pakistan Economic Corridor, the China–Central Asia–West Asia Economic Corridor and the Bangladesh–China–India–Myanmar Economic Corridor. The findings strongly indicate that BRI has been acting as a catalyst for intensifying bilateral trade preferentiality between China and the Belt-Road countries.

Authors: Parzinger Michael , Hanfstaengl Lucia , Sigg Ferdinand , Spindler Uli , Wellisch Ulrich , Wirnsberger Markus
Published: August 2020

Faults in Heating, Ventilation and Air Conditioning (HVAC) systems affect the energy efficiency of buildings. To date, there rarely exist methods to detect and diagnose faults during the operation of buildings that are both cost-effective and sufficient accurate. This study presents a method that uses artificial intelligence to automate the detection of faults in HVAC systems. The automated fault detection is based on a residual analysis of the predicted total heating power and the actual total heating power using an algorithm that aims to find an optimal decision rule for the determination of faults. The data for this study was provided by a detailed simulation of a residential case study house. A machine learning model and an ARX model predict the building operation. The model for fault detection is trained on a fault-free data set and then tested with a faulty operation. The algorithm for an optimal decision rule uses various statistical tests of residual properties such as the Sign Test, the Turning Point Test, the Box-Pierce Test and the Bartels-Rank Test. The results show that it is possible to predict faults for both known faults and unknown faults. The challenge is to find the optimal algorithm to determine the best decision rules. In the outlook of this study, further methods are presented that aim to solve this challenge.

Published: August 2020

In this paper, we mainly put the Lie symmetry analysis method on the Gibbons-Tsarev equation (GTe) to obtain some new results, including some Lie symmetries, one-parameter transformation groups, explicit invariant solutions in the form of power series. Subsequently, the self-adjointness of the GTe is singled out. It follows that the conservation laws associated with symmetries of GTe are constructed with the aid of Ibragimov’ method. Finally, we present the Bäcklund transformations so that more abundant solutions can be worked out.

The rabies virus strain Komatsugawa (Koma), which was isolated from a dog in Tokyo in the 1940s before eradication of rabies in Japan in 1957, is known as the only existent Japanese field strain (street strain). Although this strain potentially provides a useful model to study rabies pathogenesis, little is known about its genetic and phenotypic properties. Notably, this strain underwent serial passages in rodents after isolation, indicating the possibility that it may have lost biological characteristics as a street strain. In this study, to evaluate the utility of the Koma strain for studying rabies pathogenesis, we examined the genetic properties and in vitro and in vivo phenotypes. Genome-wide genetic analyses showed that, consistent with previous findings from partial sequence analyses, the Koma strain is closely related to a Russian street strain within the Arctic-related phylogenetic clade. Phenotypic examinations in vitro revealed that the Koma strain and the representative street strains are less neurotropic than the laboratory strains. Examination by using a mouse model demonstrated that the Koma strain and the street strains are more neuroinvasive than the laboratory strains. These findings indicate that the Koma strain retains phenotypes similar to those of street strains, and is therefore useful for studying rabies pathogenesis.

The last seven years have seen the greatest surge of Ebola virus disease (EVD) cases in equatorial Africa, including the 2013–2016 epidemic in West Africa and the recent epidemics in the Democratic Republic of Congo (DRC). The vaccine clinical trials that took place in West Africa and the DRC, as well as follow-up studies in collaboration with EVD survivor communities, have for the first time allowed researchers to compare immune memory induced by natural infection and vaccination. These comparisons may be relevant to evaluate the putative effectiveness of vaccines and candidate medical countermeasures such as convalescent plasma transfer. In this study, we compared the long-term functionality of anti-EBOV glycoprotein (GP) antibodies from EVD survivors with that from volunteers who received the recombinant vesicular stomatitis virus vectored vaccine (rVSV-ZEBOV) during the Phase I clinical trial in Hamburg. Our study highlights important differences between EBOV vaccination and natural infection and provides a framework for comparison with other vaccine candidates.
Regional Groundwater Modeling of the Guarani Aquifer System
Authors: Gonçalves Roger D. , Teramoto Elias H. , Chang Hung K.
Published: August 2020

The Guarani Aquifer System (GAS) is a strategic transboundary aquifer system shared by Brazil, Argentina, Paraguay and Uruguay. This article presents a groundwater flow model to assess the GAS system in terms of regional flow patterns, water balance and overall recharge. Despite the continental dimension of GAS, groundwater recharge is restricted to narrow outcrop zones. An important part is discharged into local watersheds, whereas a minor amount reaches the confined part. A three-dimensional finite element groundwater-flow model of the entire GAS system was constructed to obtain a better understanding of the prevailing flow dynamics and more reliable estimates of groundwater recharge. Our results show that recharge rates effectively contributing to the regional GAS water balance are only approximately 0.6 km3/year (about 4.9 mm/year). These rates are much smaller than previous estimates, including of deep recharge approximations commonly used for water resources management. Higher recharge rates were also not compatible with known 81Kr groundwater age estimates, as well as with calculated residence times using a particle tracking algorithm.

Many mountainous regions of the humid tropics experience serious soil erosion following rapid changes in land use. In northern Lao People’s Democratic Republic (PDR), the replacement of traditional crops by tree plantations, such as teak trees, has led to a dramatic increase in floods and soil loss and to the degradation of basic soil ecosystem services such as water filtration by soil, fertility maintenance, etc. In this study, we hypothesized that conserving understory under teak trees would protect soil, limit surface runoff, and help reduce soil erosion. Using 1 m2 microplots installed in four teak tree plantations in northern Lao PDR over the rainy season of 2017, this study aimed to: (1) assess the effects on surface runoff and soil loss of four understory management practices, namely teak with no understory (TNU; control treatment), teak with low density of understory (TLU), teak with high density of understory (THU), and teak with broom grass, Thysanolaena latifolia (TBG); (2) suggest soil erosion mitigation management practices; and (3) identify a field visual indicator allowing a rapid appraisal of soil erosion intensity. We monitored surface runoff and soil loss, and measured teak tree and understory characteristics (height and percentage of cover) and soil surface features. We estimated the relationships among these variables through statistics and regression analyses. THU and TBG had the smallest runoff coefficient (23% for both) and soil loss (465 and 381 g·m−2, respectively). The runoff coefficient and soil loss in TLU were 35% and 1115 g·m−2, respectively. TNU had the highest runoff coefficient and soil loss (60%, 5455 g·m−2) associated to the highest crusting rate (82%). Hence, the soil loss in TBG was 14-times less than in TNU and teak tree plantation owners could divide soil loss by 14 by keeping understory, such as broom grass, within teak tree plantations. Indeed, a high runoff coefficient and soil loss in TNU was explained by the kinetic energy of rain drops falling from the broad leaves of the tall teak trees down to bare soil, devoid of plant residues, thus leading to severe soil surface crusting and soil detachment. The areal percentage of pedestal features was a reliable indicator of soil erosion intensity. Overall, promoting understory, such as broom grass, in teak tree plantations would: (1) limit surface runoff and improve soil infiltrability, thus increase soil water stock available for both root absorption and groundwater recharge; and (2) mitigate soil loss while favoring soil fertility conservation.
Measurement of Apparent Electrical Impedance of Soil with Water Flow Inside
Authors: Talapessy Ronaldo , Ikegami Tomoaki , Yoshida Hiroaki
Published: August 2020

Understanding the flow of groundwater is very important, not only for water management but also for the prevention and mitigation of natural disasters. The electrical resistivity method has been established as an effective groundwater exploration method in geological surveys. The purpose of this study is to develop an accurate investigation method for groundwater flow using soil impedance fluctuations. As a preliminary experiment, the apparent soil impedance was measured by applying a low-frequency current through a soil column with water flow inside. The apparent impedance showed fluctuations due to water flow at frequencies above 20 Hz, and the fluctuation range increased with the flow rate of water. It has been proposed that groundwater flow can be detected by measuring impedance fluctuations, and it is considered that this method can be applied to groundwater surveys and embankment and reservoir leak surveys.

Internal Medicine Residents’ Perceptions of Nephrology as a Career: A Focus Group Study
Authors: Beck Natalie , Furgeson Seth , Chonchol Michel , Kendrick Jessica
Published: August 2020

Background

Interest in nephrology as a career has declined dramatically over the past several years. Only 62% of nephrology fellowship positions are filled for the upcoming 2020 appointment year. The purpose of this study was to identify perceptions, attitudes, motivators, and barriers to a career in nephrology among internal medicine residents.

Methods

We recruited focus groups of internal medicine residents (N=25) from the University of Colorado, and asked questions aimed at exploring perceptions, attitudes, and barriers to a career in nephrology, and ways to increase interest in nephrology. All focus groups were conducted on the University of Colorado Denver Anschutz Medical Campus. Focus group sessions were recorded and transcribed. Thematic analysis was used to identify key concepts and themes.

Results

Residents described many barriers to a career in nephrology, including lack of exposure, lack of advances in the field, low monetary compensation, high complexity, lack of role models/mentors, and low-prestige/noncompetitive nature of the field. Most residents had no exposure to outpatient nephrology. Lack of new therapeutics was a significant deterrent to nephrology. Nephrology teaching in medical school was described as not clinically relevant and too complicated. Several residents felt they were not smart enough for nephrology. Only three residents had a role model within nephrology. Residents used the word “stigmatized” to describe nephrology, and discussed how low prestige decreased their interest in a field. Participants expressed suggestions to increase interest in nephrology through earlier and more outpatient nephrology exposure, enhanced interactions with nephrologists, and research and advancements in the field.

Conclusions

Residents identified several modifiable barriers to a career in nephrology. Changing how nephrology is taught in medical school, enhancing interactions with nephrologists through increased exposure, and highlighting research and advancements in nephrology may change the perception of nephrology and increase the number of residents entering the field.

Published: August 2020

Acute Appendicitis is a surgical emergency. Patients present with pain in right lower abdomen, with other symptoms like nausea/vomiting, fever, diarrhoea, urinary symptoms. Diagnosis is based on a multimodality approach that includes, clinical, radiological and pathological findings. Alvarado Score helps determine the severity of infection, confirm diagnosis and guide further management. Management is either conservative with antibiotics or surgical depending on severity. However approach to surgical management has changed with the ongoing Covid-19 pandemic. It has necessitated categorisation of surgical procedures into essential and non essential to limit risk to both patient and surgical team and also for prioritization of resources to the rising, continued spread of Covid-19. We present a prospective study of 25 cases of appendicitis presenting during the Covid Pandemic between 15th March and 30th May to our hospital, with an intent to try conservative management for all patients except in the presentations with complications like perforation, abscess or the presence of fecolith or poor response to conservative management.Patients not amenable to conservative management were treated by Open appendicectomy.

Este artículo se propone transmitir la experiencia de trabajo realizada en un dispositivo interdisciplinario de salud en una institución carcelaria. Con el propósito de analizar cómo incide la cárcel, entendida como institución total en procesos de desubjetivación, se analizarán dos tiempos de trabajo distinto. Por un lado, un momento en el que los sujetos se encuentran sumergidos en la dinámica institucional. Allí se situarán tres vías que la institución propone y que inciden en la obturación de la emergencia del sujeto del inconsciente. Por otro lado, se situarán efectos que aparecen en el discurso de los sujetos en los momentos en los que la puerta se abre y con ello aparece la posibilidad de apertura de lo psíquico.

Majlis Ta’lim: Institution for Strengthening Islamic Moderation
Authors: Hafidz Muh.
Published: August 2020

This article aims at answering the questions on how the strategy used by majlis ta’lim developed in the Nahdliyyin community in strengthening Islamic moderation in this globalization era, and what are its advantages as a non-formal institution. In terms of answering these questions, the writer used the technique of collecting the data through interviews and observation. Considering that this study tends to be traditional, there is no need for written documents. The interview was conducted with the Muslim figures as activists of majlis ta’lim, and the observation was carried out through joining the recitation held by Muslimat. The collected data show that majlis ta’lim is a strategic place for strengthening and building Islamic moderation. Its strategy is carried out in several ways. First, inviting Islamic moderation figures to majlis ta’lim. Second, determining moderate themes as the main focus of the recitation. Third, optimizing majlis ta’lim as a massive movement. The advantages of majlis ta’lim as one of the public forums for Muslim community are: First, majlis ta’lim is a forum for education and teaching followed by its members. Second, the emotional relation among those members is stronger as compared to those in other forums. Third, the recitation in majlis ta’lim makes no difference in the profession, occupation, and position of the members.
Social Finance and Sustainable Development Goals: A Literature Synthesis, Current Approaches and Research Agenda
Authors: Rizzello Alessandro , Kabli Abdellah
Published: August 2020

The debate, especially in policy circles, around the emergence of Social and Sustainable Finance (SSF), depict as ‘paradoxical’ the contrast between SSF as a relatively under-developed field of knowledge and thought, and yet as an area of practice with ‘vast potential’ that is experiencing an ‘explosion’ in practitioner numbers. Such potential, in term of economic and social value that SSF can deliver, is reflected in the increasing of interest within the public policy-making arena in the achievement of Sustainable Development Goals (SDGs). More in detail, it is also underlined by the raising of public and private investment into promoting and supporting them. Within such evolving arena, the exact scale and scope of SSF’s contribution to the improvement of SDGs worldwide is difficult to delineate and measure accurately, but there seems to be universal agreement that SDGs represent an ideal and widespread area where SSF can register a significant growth. However, limited research addressed the marriage of these two fields. The purpose of this research are: i) to shed light on existing academic literature embracing both Social and Sustainable Finance and SDGs issues, ii) explore emerging trends deriving from international policy-making actors, market builders, managers, senior academics and, iii) to identify the main areas for further research focusing on SSF and SDGs. In order to derive a research agenda about such emerging research topic, the study adapts a triangulated approach based on qualitative mixed methods. With such objectives in mind, the study provides an extensive literature review in order to depict a comprehensive overview of existing knowledge considering both SSF and SDGs topics. The analysis is therefore enhanced by the trends identified from literature deriving from public policy-making actors and market-builders as well as from invited commentaries on SSF from senior scholars and managers. Thus, a holistic perspective on SSF experience, useful to identify the main areas for further research on SSF in the sustainability industry, was derived. The study, therefore, aims to provide, through a triangulated analysis of the concepts, frameworks and trends, a detailed understanding of the mechanisms for managing the interplay between SSF and SDGs, by highlight future avenues of research in this field.

The key to success in patients with difficult airway is effective airway assessment and meticulous planning. Making use of simple and time-tested equipment and modifying these methods accordingly enable successful airway control avoiding perioperative morbidity and mortality . We report a case of 75 year old male with posterior urethral stricture planned for perineal urethroplasty with anticipated difficult airway. The airway was managed using video laryngoscopy and the procedure was uneventful with good postoperative recovery. This case report insists on making use of other conventional methods in the effective management of an anticipated difficult airway during a pandemic.
RATIO OF SERUM CA125 TO RADIOLOGICAL PERITONEAL CARCINOMATOUS INDEX AS A NOVEL MARKER OF RESPONSE TO NEO ADJUVANT CHEMOTHERAPY AND PREDICTIVE MODEL OF SURGICAL OUTCOME IN ADVANCED EPITHELIAL OVARIAN CANCER- A SINGLE INSTITUITIONAL STUDY.

Published: August 2020

Objective:
The objective of this retrospective study is to develop a novel marker- ratio of serum CA 125 to peritoneal carcinomatous index(PCI) - to predict the response in women receiving neoadjuvant chemotherapy for newly diagnosed advanced epithelial ovarian cancer at our centre.
Methods:
Medical records of women who were newly diagnosed with inoperable advanced ovarian cancer stages III and IV at our centre were selected. Only people with completely documented records in the years 2017 & 2018 were selected. Only patietns with serous histology were chosen. Pre chemotherapy serum CA125 value was noted. Radiological PCI was calculated by reviewing the CECT films & reports of the patients.
Patients were compared with the ratio of CA125 to radiological PCI and clinical & pathological response to neo adjuvant chemotherapy. All patients received standard doses of three weekly Paclitaxel and Carboplatin based chemotherapy. Based on the ratio of CA125 to PCI patients were divided into 2 groups – ratio more than 100 and less than 100.
Results:
A total of 34 were patients were found to meet the eligible criteria. Response assessment was done after 3 to 4 cycles of neoadjuvant chemotherapy. The overall response rate to neoadjuvant chemotherapy in patients in group 1 ( CA125/PCI ratio > 100) was significantly higher as compared to patients in group 2 (CA125/PCI ratio <100).
Conclusion:
In summary, CA 125 to PCI ratio is novel method to predict response to chemotherapy in advanced epithelial ovarian cancers. This value is a helpful measurement that allows the clinicians to measure the degree of chemosensitivity prior to cytoreductive surgery. This measures the inherent tumor biology and to aids in surgical decision making regarding the role and extent of cytoreduction as well as alternate systemic/local therapies.

The three factors which aid for success of a prosthesis are stability, retention and support which have physiological effect, psychological effect, longevity to the prosthesis respectively. Adhesives are the chemical retentive aids which may also give psychological confidence for the patient as it supplements retention and stability especially during occasions of public interaction. Adhesive Dentistry is a, relatively, new field that has totally revolutionized the face of dentistry. It is based on the concept of adhesion. Innovations in dentistry have always been related to the development of new materials, techniques &equipment’s and thus, were always subject to changing and disappearing with the evolution of newer ones. For the first time, the innovation related to adhesion is concept related, whereas the materials & techniques are revolving and changing around this concept to satisfy it and improve it without changing it.1,2

Star Topology Convolution for Graph Representation Learning
Authors: Wu Chong , Feng Zhenan , Zheng Jiangbin , Zhang Houwang , Cao Jiawang , YAN Hong
Published: August 2020

We present a novel graph convolutional method called star topology convolution (STC). This method makes graph convolution more similar to conventional convolutional neural networks (CNNs) in Euclidean feature spaces. STC learns subgraphs which have a star topology rather than learning a fixed graph like most spectral methods. Due to the properties of a star topology, STC is graph-scale free (without a fixed graph size constraint). It has fewer parameters in its convolutional filter and is inductive, so it is more flexible and can be applied to large and evolving graphs. The convolutional filter is learnable and localized, similar to CNNs in Euclidean feature spaces, and can share weights across graphs. To test the method, STC was compared with state-of-the-art graph convolutional methods in a supervised learning setting on nine node properties prediction benchmark datasets: Cora, Citeseer, Pubmed, PPI, Arxiv, MAG, ACM, DBLP, and IMDB. The experimental results showed that STC achieved state-of-the-art performance on all these datasets and maintained good robustness. In an essential protein identification task, STC outperformed state-of-the-art essential protein identification methods. An application of using pretrained STC as the embedding for feature extraction of some downstream classification tasks was introduced. The experimental results showed that STC can share weights across different graphs and be used as the embedding to improve the performance of downstream tasks.
