Published: November 2021

Background. COVID-19 showed similar and overlapping symptoms compared with seasonal influenza. It is difficult to distinguish them, especially in the early stage of the outbreak. The confluence of the two diseases might result in considerable morbidity, it is doubtful that whether COVID-19 had already affected the morbidity of influenza earlier than the first report.Methods. We conducted Kolmogorov-Smirnov Test and Kruskal Wallis Test to discover seasonal and regional distributions of influenza and COVID-19. Cluster analysis was utilized to explore possible influence factors. Spearman Test was carried out for analyzing correlations between the two diseases. We employed Arima Model to predict time series of WMI. We proved differences between the forecasted and the original time series of influenza from 2019 to 2021 by Mann-Whitney U Test. Then we observed first abnormal peaks on the time series, tracing back to the onset of COVID-19 affecting influenza compared with the first-report time.Results. WMI and WMC varied significantly in four seasons, five continents and the ten selected countries. Cluster analysis divided the data into two groups according to country, continent, population and morbidity. WMI of China, Israel, Honduras, Morocco and Nigeria were correlated with WMC. The forecasted and the original time series of influenza from 2019 to 2021 were significantly different. Compared with the forecasted one, some abnormal peaks firstly appeared on the original time series of influenza around Dec.31st, 2018 on Austria, Norway, Morocco and Nigeria, Jan.28th, 2019 on South Africa, Apr.8th, 2019 on Marshall Islands, Jul.7th, 2019 on America, Sep.30th, 2019 on China and Israel, Mar.11th, 2020 on Honduras.Conclusions. Winter and autumn were the high incidence season for influenza and COVID-19, respectively. Oceania and Americas owned the highest incidence rate for these two diseases. Human immunity, continents, countries’ policies and population were possible influence factors. Only in Honduras, the first reported COVID-19 case happened concurrently with the abnormal value of the ILI. And in the rest of the included countries, COVID-19 might happen earlier than its first reports. Among these regions, COVID-19 might firstly affect Africa in the first week of 2019.

Published: November 2021

The copula-based joint distribution can construct a fire risk model to improve forest fires' early warning system, especially in Kalimantan. In this study, we model and analyze the copula-based joint distribution between climate conditions and hotspots. We used several climate conditions, such as total precipitation, dry spells, and El Nino-Southern Oscillation (ENSO). We used copula functions with sample size reduction to construct the joint distributions and the copula regression model to estimate the fire size. The results show that the probability of extreme hotspots number during normal ENSO conditions is very rare and almost near zero during La Nina. Other than that, extreme hotspot event (more severe than in 2019) during El Nino is more sensitive to total precipitation than dry spells based on the conditional survival function. However, the copula regression model found that the model used dry spells as a climate condition better than total precipitation. In this model, the 95% confidence interval of the expected hotspots can cover all actual hotspots data.

Published: November 2021

Purpose

Around three quarters of individuals undergoing chemotherapy self-report multiple symptoms. There is clinical trial evidence of effectiveness for acupuncture for commonly experienced symptoms, and emerging evidence for reflexology, but little is known about the effects of these therapies on multiple symptoms when implemented in a real world setting during active chemotherapy treatment.
Methods

This was a single-arm observational study of participants receiving reflexology and/or acupuncture while attending chemotherapy. Participants received a 20 minute reflexology treatment or a 20 minute acupuncture treatment or a combination of both. Patient reported outcome measures were administered before and after the treatment using the Edmonton Symptom Assessment Scale (ESAS).
Results

During the study period, 330 unique participants with cancer received acupuncture and/or reflexology treatments. Participants had, on average, 5.3 symptoms each which they reported as moderate to severe (≥4/10) using the ESAS at baseline. Following treatment, participants reported 3.2 symptoms as moderate to severe. The symptom change for all participant encounters receiving any therapy was statistically significant for all symptoms, and clinically significant (a reduction of more than 1) for all symptoms except financial distress, appetite and memory. Clinically significant levels of global distress (<3) were reduced in 72% of all participants receiving either therapy. No adverse events were recorded.
Conclusions

The results indicate that acupuncture and reflexology administered alongside chemotherapy may reduce patient reported symptom burden and patient global symptom related distress. Future research would include an active control group, and consider confounding factors such as chemotherapy stage and medication.

Personalized neoantigen vaccines have shown strong immunogenicity in clinical trial, but still face various challenges in facilitating an efficient antitumour immune response. Here we prepared a personalized neoantigen nanovaccine (PNVAC) platform for adjuvant cancer immunotherapy. PNVAC triggered superior protective efficacy against tumor recurrence and promoted longer survival than free neoantigens, especially when combined with anti-PD-1 treatment in a murine tumor model. A phase I clinical trial (ChiCTR1800017319) was initiated to study the safety, immunogenicity, and prophylactic effect of PNVAC on preventing tumor recurrence in patients with high-risk gastric/gastroesophageal junction cancer after adjuvant chemotherapy post-surgical resection. The 1- and 2-year disease-free survival rates were significantly higher than historical control. PNVAC induced both CD4+ and CD8+ T cell responses as well as antigen-experienced memory T cell phenotype. Furthermore, the immune response was persistent and remained evident one year after the vaccination. Our work provides a safe and feasible strategy for development of neoantigen vaccines to delay gastric cancer recurrence after surgery.
Molecular Cloning, Expression and Insilco Analysis of Drought Stress Inducible MYB Transcription Factor Encoding Gene From C4 Plant Eleusine Coracana
Authors: BHATT MEGHA
Published: November 2021

Drought is one of the key abiotic stresses that critically influences the crops by restraining their growth and yield potential. Being sessile, plant tackle the detrimental effects of drought stress via modulating the cellular state by changing the gene expression. Such alteration of gene expression is essentially driven by the transcriptional syndicate. Transcription factors (TF) are the key regulatory protein that controls the expression of their target gene by binding to the cis-regulatory elements present in the promoter region. Myb-TF subiquitously present in all eukaryotes belong to one of the largest TF family, and play wide array of biological functions in plants including anthocyanin biosynthesis, vasculature system, cell signaling, seed maturation and abiotc stress responses. In the present study, isolation, and molecular cloning of full length Myb TF from Eleusine corocana has been performed. The isolated full-length coding sequence has 1053 bp and 350 aa was submitted to NCBI (Accession number MT312253). The transcript level of EcMYB increases under different abiotic stress treatment including dehydration, salinity, and high temperature stress. The promoter region of EcMyb1 was found to be enriched in stress-responsive cis-regulatory elements such as DRE, HSE, ABRE etc. In phylogenetic analysis, EcMyb1 appeared to have high homology with its monocot orthologs particularly Sateria italica, Hordeum vulgare, Saccharum barberi and Oryza sativa. The three-dimension protein structure was generated based on homology modeling and structural aspects were discussed. Further, Insilco analysis was conducted to explore the physiological properties, subcellular localization, potential post-translational modification sites (phosphorylation and glycosylation sites), and molecular and biological function of full-length protein. Overall, the expression profiling and Insilco analysis of EcMyb1 strongly indicated its potential role in abiotic stress response in Eleusine corocana.

The electronic absorption and fluorescence emission spectra of N-(2,5-dimethyl-pyrrol-1-yl)-2-(5-methoxybenzofuran-3-yl)acetamide (DPMA) molecule were recorded in various solvents at room temperature with the aim of estimation of ground state (\({\mu }_{g}\)) and excited states (\({\mu }_{e}\)) dipole moments using Lippert’s, Bakshiev’s and Kawski-Chamma-Viallete’s equations. The results were signified that, the excited state dipole moment is greater than the ground state dipole moment, which indicates the excited state dipole moment is more polar than the ground state dipole moment. Ecofriendly green synthesis of silver nanoparticles (Ag NPs) were synthesized using catharanthus roseus (C.R) leaf extract was done. These synthesized Ag NPs were used as fluorescence quenchers. Fluorescence lifetime measurement is carried out using time correlated single photon counting technique of DPMA molecule with various concentrations of Ag NPs. A linear Stern-Volmer (S-V) plot was obtained in steady state and transient state method. Furthermore we have estimated computational calculations such as ground state optimized geometry, molecular electrostatic potential (MEP), highest occupied molecular orbital (HOMO), lowest unoccupied molecular orbital (LUMO), experimental and theoretical energy band gap, solvent polarity and normalized solvent polarity values. Morphology and sizes of green synthesized silver NPs were characterized by transmission electron microscopy (TEM) with energy dispersive X-ray spectroscopy (EDX) and also characterized by UV-Visible absorption.
Accuracy and Reliability of the Optoelectronic Plethysmography and the Heart Rate Systems for Measuring Breathing Rates Compared with the Spirometer.
Authors: Stubbe Laurent , Houel Nicolas , Cottin François
Published: November 2021

Measuring breathing rates without a mouthpiece is of interest in clinical settings. Electrocardiogram devices and, more recently, optoelectronic plethysmography (OEP) methods can estimate breathing rates with only a few electrodes or motion-capture markers placed on the patient. This study estimated and compared the accuracy and reliability of three non-invasive devices: an OEP system with 12 markers, an electrocardiogram device and the conventional spirometer. Using the three devices simultaneously, we recorded 72 six-minute epochs on supine subjects. Our results show that the OEP system has a very low limit of agreement and a bias lower than 0.4% compared with the spirometer, indicating that these devices can be used interchangeably. We observed comparable results for electrocardiogram devices. The OEP system facilitates breathing rate measurements and offers a more complete chest-lung volume analysis that can be easily associated with heart rate analysis without any synchronisation process, for useful features for clinical applications and intensive care.

Authors: E Dragomir
Published: November 2021

The power analysis of the entire three-phase electrical system provides brief indications due to the compensation between the phases of the system of active and reactive powers. Only analysis of the electrical phases characteristics (currents, voltages, powers) of the three-phase system has theoretical and practical particular importance for balancing systems as well as analyzing the currents and powers that load the phases of the system. Akagi's "imaginary reactive power" method offers low efficiency and is polluting, introducing three order parasitic harmonics (compensating currents containing only half of the currents to be compensated) for three-phase unsymmetrical systems.

Published: November 2021

Social relations regarding economic transport activity in maritime ports require a clear, concise and coherent body of legislation to support the transport community and the representatives of related industries, so that they can pursue their proposed business objectives, a fair, competitive and safe public order environment. We believe that piloting and sea towing must be circumscribed by this desideratum, a poor legal regulation making it difficult for ships to enter and exit from and to the Port of Constanta and, moreover, be able to cause a real economic or environmental disaster. In this respect, we have proposed in the present paper to analyze from the perspective of legal regulations, as a case study, the most important piloting accident that occurred in the Romanian ports on November 1st 2015 between two commercial ships flag Malta and Turkey, showing the consequences, as well as the potential dangers that could have occurred.

Authors: Handika Rangga
Published: November 2021

This paper offers a new measurement of risk, Value-at-Risk (VaR) for LQ-45 index in Indonesian Stock Exchange (ISX). Basic finance uses standard deviation in measuring and quantifying the risks. This paper uses VaR as a risk measure by using historical and analytical methods. This study uses the data containing all LQ-45 weekly data from January 1st, 2005 to December, 31st 2010. Moreover, this paper also calculates VaR of three indices (IHSG, Dow Jones, and S&P 500) for benchmarking purpose. This study finds that LQ-45 companies have VaR ranging from -5.30 to -41.05 percent with 95 percent level of confidence. It means that we can expect to suffer a minimum weekly loss between 5.30 to 41.05 percent in 5 percent probability when we invest in the LQ-45 companies stocks individually. Furthermore, this study finds that individual LQ-45 stock is riskier than indices based on VaR measure. This paper also concludes that individual LQ-45 stock tends not to follow normal distribution while index tends to follow by comparing their historical and analytical VaR calculation.

Authors: Lingga Doan Siscus Kaldianto , Tirok Junius
Published: November 2021

This research analyzes the influence of Economic Value Added (EVA) and profitability ratios measurement on Indonesian public companies stock returns. The companies are firms that are listed in the Indonesia Stock Exchange (IDX) and that take part in the LQ45 group. The profitability ratios that are used in this research are profit margin (PM), return on sales (ROS), return on equity (ROE), and return on assets (ROA). The aim of this research is to prove the claim that EVA is associated more with company annual stock return rather than profitability ratios. The methodology that is used in this research is a multiple regression test to measure the significance between EVA, profit margin (PM), return on sales (ROS), return on equity (ROE), and return on assets (ROA) with the company annual stock returns. The research result shows that in the end the research prove that EVA does not influence profitability ratios in association with company stock returns. The evidence indicates that profitability ratios are closely associated with company stock returns with the highest significance. More specificly, return on equity (ROE) is the most associated profitability ratio with stock returns followed by return on assets (ROA).

Published: November 2021

This research investigates the significant influence of family ownership on firm performance in order to provide information to decision makers and other interested parties. The analysis includes comparisons between family and non-family firm performance in Indonesia. The samples are taken from 31 consumer goods companies, listed on the Indonesian Stock Exchange, ranging from 2005 to 2009. The results show that non-family firms perform better than family firms and no significant influence between family ownership and firms’ profitability. On the other hand, family ownership has negative contribution to firm market valuation. The study suggests that family firms have lower financial performance than that of non-family.  Family members within the top position have major control rights and contribute a negative influence to firm performance. The evidence raises concerns about possible profit manipulation and weak governance law in Indonesia, and as a result there is an expropriation of wealth to the majority and family related shareholders.
DO INDONESIAN MANAGERS TIME THEIR CORPORATE BONDS?
Authors: Andreani Christine , Tamara Dewi
Published: November 2021

Corporate bonds are becoming popular in Indonesian capital market due to the ongoing decline in interest rates and the increase in credit rating. Debt Market Timing Theory argues that managers try to time their bonds issuance according to the market interest rate, relatively. This paper aims to analyze the debt issuance timing profile of Indonesian public listed companies. The samples are 24 bonds issuances, which have maturity period between 3 to 7, and companies already issued more than 1 bond issued within year 2009 and 2011. The manager’s behavior to time government bond rates is observed in the 5 working days window, whether the corporate bonds being issued at the lowest market interest rate (i.e., government bond rates) on the window. Bootstrap method is utilized to construct counterfactual data. The research finds that 7 out of 24 bonds issuance were issued at the lowest government bond yield within the window. Indonesian public listed companies had no ability to time their bond issuances during period 2009 until 2011. This paper reveals that the frequency of bond issuances made by each Indonesian company does not necessarily determine their capability to time government bond rates. However, bootstrap is a useful and more robust tool to help assessing the debt market timing ability when the samples taken are small in numbers.

Sales forecasting is essential for decision-making and are crucial in many areas of a firm, such as planning and scheduling, resource management, marketing, logistics, and supply chain. Due to the fluctuations in retail sales, prediction with high accuracy is a challenging task. In this context, this study proposes a framework that combines ensemble empirical mode decomposition (EEMD) based on artificial intelligence models to forecast the retail sales of a Rossmann Store, using a multi-step-ahead forecasting strategy, in the task of time series forecasting with one, seven, and fourteen-days-ahead. The forecasting models of the retail sales time series are Bayesian Regularization of Artificial Neural Networks, Cubist Regression, and Support Vector Regression. The performance of the proposed forecasting models were evaluated by using two performance metrics: mean absolute percentage error and root mean squared percentage error. The EEMD models outperform the single models in all forecasting horizons, with a performance improvement that ranges 1.30% – 76.25%. Indeed, EEMD models are efficient and accurate models for retail sales forecasting.

Time series forecasting has become an important task for several industrial processes. The employment of machine learning techniques also contributed to reduce costs and increase profits. In order to achieve accurate forecasts, it is important to perform a proper selection of parameters for the forecasting models. Hybrid sequential systems reduces model uncertainty through the employment of different models in the time series and residual series. In this work, an ensemble based hybrid sequential system is proposed, where a heterogeneous ensemble is used to perform residual forecasts. In this way, a pool of four models used in the industrial scenario are employed in order to achieve accurate forecasts. The experiments were conducted on real datasets from the industry in hourly averages and daily averages. The results show that the proposed system achieved promising results, and was able to improve the accuracy of the models in the pool in several cases.

Dengue is considered a public health problem in tropical regions, periodically affecting an increasing number of citizens. Consequently, the development of efficient models is essentials to short and long-term forecasting, supporting health care officials to optimally disseminate available resources in the dengue-prone areas. Hybridization of two or more models is a common solution to this problem where one can take advantage of diversity among models to reduce both the bias and variances of the prediction error obtained using single models. Fortunately, the use of ensemble approaches becomes attractive. In this paper, we propose a novel ensemble learning approach combining the eXtreme Gradient Boosting (XGBoost) and Coyote Optimization Algorithm (COA) to capture the nonlinearity in a dataset and perform dengue cases forecasting. The performance of the XGBoost model depends upon the appropriate choice of its hyperparameters. In this study, COA has been employed to tune the XGBoost hyperparameters. The proposed hybrid COA-XGBoost model is applied to predicting dengue time-series dataset from Parana, Brazil. Averages of precipitation, temperature, thermal amplitude, relative humidity, and previous dengue cases are considered as input variables as well as dengue cases are used as output variables. The performance of the proposed COA-XGBoost model has been compared with XGBoost when hyperparameters are obtained using other optimization techniques like Differential Evolution, Genetic Algorithm, Cuckoo Search Optimization, Grey Wolf Optimizer, and Firefly Algorithm. The results indicate that the proposed COA–XGBoost can be competitive model when compared to other classical techniques.

Published: November 2021

A hydrodynamic model is developed for rainfall–runoff on asphalt pavement using two-dimensional shallow water equations. A simple yet precise expression is presented to compute flow velocity in order to alleviate the problems associated with numerical instabilities due to small water depths of thin sheet flow. The developed model performed well against measured data and numerical results in two segments. Then, the model was applied to study the influence of highway horizontal alignment, drainage manner, rainfall pattern, surface roughness and geometric parameters on pavement runoff. The results demonstrate that: (i) the influence of highway horizontal alignment on pavement runoff is nonsignificant, while that of drainage manner and the pavement surface roughness is significant. Great differences are observed in flow depth under concentrated drainage and overflow drainage conditions, especially in the area beyond 6 m away from the highway center axis; (ii) remarkable differences in maximum flow depth and peak runoff are presented under uneven and even rainfall conditions, while no great differences are found under three uneven rainfall conditions (front type, center front type and back front type); (iii) the sensitivity of the geometric parameters to the maximum flow depth from strong to weak is cross slope, width, slope length, and longitudinal slope under overflow drainage condition; while that is width, slope length, longitudinal slope and cross slope under concentrated drainage condition.

There have always been different methods of teaching and learning of English language and throughout the years these methods have changed and improved. The Grammar Translation Method is one of the first and the main methods in teaching and learning of English language. This method enables the learning through the translation of various texts and the study of grammatical rules, which is its main activity. Moreover, in a class where Grammar Translation Method is used the target language is used less while the students are mainly taught in their national language, i.e. L1. Therefore, since this method was less effective in preparing the learners to use the target language communicatively, a new method was introduced. Thus, the Direct Method became used and popular among learners and teachers.
