BERT-RCNN: an Automatic Classification of App Reviews using Transfer Learning based RCNN Deep Model
Authors: Kaur Kamaljit , Kaur Parminder 
Published: January 2023

Abstract
App reviews considered as the major concern over the internet. It influences the user’s mind before purchasing the app. However, such user reviews might contain technical information about the app that can be valuable for the developers and software companies. Due to pervasive use of mobile apps, large amount of data is created by users on daily basis. Manual identification and classification of such reviews is very time-consuming and laborious task. Hence, automating this process is essential for helping developers in managing these reviews efficiently. Recently, traditional machine learning and deep learning oriented approaches have been exploited for classification of app review into software requirements. Most of the machine learning techniques utilizes traditional word techniques to extract the features from the textual reviews. In addition, deep learning techniques with efficient word embedding technique also improve the classification performance of the model. However, it is found that these techniques suffer from polysemic problem. To address aforementioned problem, this research paper presents novel neural language based framework, BERT-RCNN to classify app reviews into specified categories of functional requirements such as Bug report, Feature Request and Relevant etc. The presented framework has two main modules: Bidirectional Encoder Representation for Transformer (BERT) module and Recurrent-Convolutional Neural Network (RCNN) module. BERT module extracts the contextual relationship between the textual reviews. Then, these features are input to RCNN module to capture more important features with deep semantic information. The output of RCNN is fed to fully connected layer for classification purpose. Extensive experiments are conducted on five datasets to investigate the effectiveness of the presented BERT-RCNN model. For evaluation purpose, standard performance measures are used to obtain the results. Moreover, hyperparameter such as BiLSTM memory unit, CNN filters and CNN kernel size are tuned to ensure the quality of prediction. Comparative analysis of proposed model is conducted with existing state-of-the-art models. It shows that BERT-RCNN outperforms other state-of-the-art models with respect to precision, recall, f-measure and accuracy.

Abstract
Purpose
Normal pressure hydrocephalus (NPH) following cranial radiotherapy (RT) has a deleterious effect on patient’s daily functioning. However, there is no consensus on its management in cancer population. The aim of our study is to examine cognitive, brain MRI and lumbar infusion test (LIT) features and to identify predictors of response to ventricular shunting (VPS) in long-term cancer survivors.
Methods
Patients who completed cranial RT at least 2 years before, with clinically suspected NPH and an Evans’ index (EI) ≥ 0.30, undergo a cognitive and a cerebrospinal fluid (CSF) volumetric (MRI) analysis (n = 36). For those in whom VPS was placed (n = 14), we explore whether adding a CSF volumetric analysis to classical MRI and LIT (Tap Test) features would better identify VPS responders.
Results
Nearly 80% of our cohort exhibited cognitive impairment, especially focused on executive functioning. There were no differences regarding clinical, LIT or MRI classical features between those who improved or were not following VPS. In contrast, CSF volume at NPH diagnoses resulted significantly larger in the group of VPS responders (p = 0.04). The addition of CSF volume to NPH diagnoses increased accuracy to 93%, with a PPV of 91% and NPV of 100%, resulting in a predictive factor of response to VPS.
Conclusion
The addition of a quantitative MRI analysis of CSF volume to classical MRI and LIT NPH criteria, together with a high clinical suspicion of NPH in long-term survivors following cranial RT, may help to identify VPS responders, thus improving the clinical management and prognosis of this population.
A micro-econometric analysis of the determinants of Households Saving Behavior in Uganda- A Multinomial logit modelling approach
Authors: Ssebulime Kurayish , Sebukeera Hennery , Wasswa Francis 
Published: January 2023

Abstract
Households have a number of saving choices to make and each of their choices has profound implications for the economy and for their standards of living. To investigate the determinants of household choice of saving mechanism, the multinomial logit model is applied. The main conclusion of this paper is that, employment status, household size, household monthly expenditure, education level, age of the household head, residence of the household, and marital status are significant determinants of household saving behavior in Uganda. It is thus recommended that, policy measures for ensuring financial inclusion should take cognizant of the differences in socioeconomic household characteristics like residence of households with regard to rural and urban based households. Further, increasing the level of education is critical for enhancing financial knowledge and is critical for enhancing adoption of formal saving mechanisms. Targeted policy actions to enhance financial knowledge should be critical in enhancing financial inclusion.

Published: January 2023

Abstract
Background:
Fractures of the hip are common injuries. Approximately 50% of hip fractures occur in the intertrochanteric region, the prevalence of which increases exponentially with age. It is also associated with a high rate of morbidity and mortality. Beyond preventing avoidable deaths, the goal of the treatment is to restore patients to their pre-injury level of mobility. (5) Achieving stable reduction and fixation of the fracture, permitting immediate mobilization, is key to these goals.
Methods:
This is a descriptive cross-sectional hospital-based design study to evaluate the early Functional outcome of proximal femoral nail anti-rotation in the treatment of unstable intertrochanteric fractures conducted in 3 centers, and the total number in our study was 40 cases. Data were collected through a questionnaire that included patient data and analyzed using SPSS software (IBM Version-26).
Results:
Out of the Forty patients with an unstable intertrochanteric femur fracture (fractures A2.2 through A3.3), operated with PFNA enrolled in this study, 22 were males and the remaining were females. 24 patients had right hip fractures while 16 had left hip fractures. . Modified Harris Hip Score was used to assess postoperative pain, function, and functional activities.
There is a statistically significant difference between the mHHS and the age group, the functional outcome was excellent in young patient and the more patient’s age the less functional outcome and gender, and most of our patients score were fair and good. 17 female patients are fallen in this category while 12 male patients. All excellent patients are male group.
Conclusion:
Unstable intertrochanteric fracture is common in the elderly due to osteoporosis and in the young due to high-velocity trauma. As the fracture is more common in the elderly (80% of our study group), early reduction and internal fixation increases patient comfort, facilitates nursing care, and helps in the early mobilization of the patient. We believed our study had shown that the PFNA works well in the treatment of unstable intertrochanteric fractures, post-operative pain was ignored in most of our patients, 60% had slight limping not compromised their daily activity, most of them used a cane for walking 2-3 blocks, 52.5% climbed the stairs with banister, 72.5% put on socks/shoes with ease, 95.0% sitting in any chair for a long time and 62.5% entered public transportation. The overall functional outcome of our patients falls between good and fair.

Abstract
Thyroid papillary carcinoma (PTC) is the most common endocrine tumor, Hashimoto's thyroiditis (HT) is considered to be closely related to PTC pathogenesis, but their relationship still needs verification and exploration. Aim of the study. To analyze the differences and similarities of the metabolic mechanism of thyroid papillary carcinoma in normal and HT background, and to explore the relationship between HT and PTC. The Ultra performance liquid chromatography-quadrupole-time of flight-mass spectrometry (UPLC-Q-TOF/MS) technology was used to analyze 61 PTC patient tissues (31 HT background and 30 normal tissue (NC) background). Potential biomarkers were screened from principal component analysis (PCA) to orthogonal partial least square (OPLS) discriminant analysis and further evaluated by ROC analysis. The HMDB was searched to identify potential differential metabolites and the final metabolic pathway analysis was performed by MetaboAnalyst 5.0. The HT and NC group had common metabolic pathways, such as taurine and hypo-taurine metabolism, arginine biosynthesis, alanine, aspartate and glutamate metabolism, arginine and proline metabolism and D-glutamine and D-glutamate metabolism. Furthermore, arginine, glutamic acid, cysteine, citric acid, malic acid, uracil and taurine showed statistical significance in PTC diagnosis (the area under the curve values of HT group and NC group were 0.867 and 0.973 respectively). The HT group had specific metabolic pathways, including aminoacyl-tRNA biosynthesis, glycine, serine and threonine metabolism. The metabolic profiles of the NC and HT groups had important similarities and differences in thyroid cancer. The correlation of PTC with HT may be related to aminoacyl-tRNA biosynthesis, serine and threonine metabolism.

Published: January 2023

Abstract
Pollinators are declining worldwide as a result of land anthropization. However, several species have shown to be not affected or even benefited, since their responses depend on their functional traits that modulate their adaptability to particular environmental conditions. Pollinator responses may have important consequences on the structure of interaction networks, as the interacting species are sensitive to their counterparts. Despite the great importance that mangrove ecosystems have for human welfare, little is known about what is happening with pollinators' diversity and their interactions with mangrove species. This study investigates landscape effects on pollinator functional composition and their interactions with four dominant mangrove species in the Caribbean coast of Colombia. Pollinators of mangrove species Avicennia germinans, Conocarpus erectus, Laguncularia racemosa, and Rhizophora mangle were classified according to different functional traits and plant-pollinator interaction networks were created, with the aim to explore general patterns and to evaluate the effects of mangrove patch size and the surrounding land uses on pollinator functional composition and plant-pollinator interactions. Pollinator communities were mainly represented by wasps, flies, and bees, with the predominance of small and medium-sized predators, saprophagous, florivorous, no-social, and no-nesting species. Plant-pollinator interactions demonstrated a trend to niche differentiation in C. erectus and R. mangle, high number of interactions and pollinator species, as well as high values of interaction diversity and interaction evenness. Mangrove patch size decreased the richness of ground nesting wasps whereas increased network specialization, and urban size decreased the richness of predators, large-sized species, and ground-nesting wasps.
Intrinsic Friction Behaviour Originating from Molecular Structure of Lubricant in Nanoscale Gap Fabricated by Microelectromechanical Systems
Authors: Yagi Wataru , Xia Yuanlin , Tsuchiya Toshiyuki , Hirayama Tomoko 
Published: January 2023

Abstract
The purpose of this study was to obtain the friction properties reflecting the molecular structure of lubricant with a film-like specimen fabricated by MEMS technology. A bias voltage is applied to a film-like specimen to create a load between two surfaces by electrostatic force. This causes the specimen to deform. The two surfaces should then become parallel. A friction test was carried out by sandwiching n-hexadecane or toluene between the specimens. The friction property with n-hexadecane was a typical slip behaviour: transition from static to kinetic friction at a sliding velocity of 0.05–0.80 µm/s. The friction property with toluene was a characteristic slip behaviour depending on the sliding velocity: at 0.05–0.20 µm/s, a clear stick-slip motion was observed.

Authors: L Vimal Raj , S Amilan , K Aparna 
Published: January 2023

Abstract
This research intends to develop and validate a research model for the adoption of cashless transactions. For this purpose, this study was carried out using a two-stage approach. The first step in developing the conceptual framework for this study was undertaking an extensive evaluation of the prior research. Second, an empirical validation of the conceptual framework that was constructed in this research to investigate the use of cashless transactions was obtained. The study results reveal that twelve independent variables explained 84.7 percent of the variation in behavioural intention to adopt cashless transactions. In addition, performance expectancy is the strongest predictor of users' intentions to embrace cashless transactions, followed by perceptions of the economy's security and economic offence reduction, social influence, perceived trustworthiness, expected level of effort, and innovativeness. Further, in terms of impediments, perceived risk and cost are the negative influence factors influencing behavioral intention to adopt cashless transactions. Furthermore, this study's findings indicate that perceived economy's security (β = 0.279) was the second, and perceived economic offence reduction (β = 0.224) was the third most influential factor in adopting cashless transactions. These findings come from an evaluation of three new independent variables. Therefore, the CTAM has contributed to the literature by comprehensively explaining the user acceptability of cashless transactions. Consequently, this CTAM offers a more in-depth explanation than any other research for why individuals embrace cashless transaction systems.

The purpose of the study was to analyze the effect of using lipid e-books using the STEM approach on student learning outcomes. The method uses pre-experimental research with one group pretest posttest design. This research was conducted at one of the State Universities in Bengkulu with the subject consisting of 26 students who took the Organic Chemistry 2 course. The instrument used in this study was a multiple choice test with 4 meetings in the form of pretest and posttest questions. Data analysis techniques include the average value (mean), normality test, and hypothesis testing using a t-test using the SPPS for windows version 23 computer program. The results showed the average score of the learning outcomes before using the lipid organic chemistry e-book was 54.90, while after using the e-book the average value is 79.81. The learning outcomes data were normally distributed and the t-test value showed Significant (2-tailed) 0.00. These results indicate that the developed STEM-based teaching materials can improve student learning outcomes in particular and are able to improve the quality of learning for organic chemistry 2 courses in general.
Waste to resource: Utilization of waste bagasse as an alternative adsorbent to remove heavy metals from wastewaters in sub-Saharan Africa: A review
Authors: Lemessa Gemechu , Gabbiye Nigus , Alemayehu Esayas 
Published: January 2023

AbstractHeavy metals pollution of both surface and groundwater sources of sub-Saharan Africa is alarmingly increased due to unplanned urban populations. Inadequate policies for water management, political commitment, and financial resources forced 65% of rural communities of sub-Saharan Africa to live in economic water stress areas. Sugarcane bagasse (SCB) shows high heavy metals (HMs) adsorption capacity (20–700 mg/g) through chemical entrapments to carbon-oxygen containing functional group and interior pore filling of porous surface. Various modifications like a physical/thermal, chemical, and composite form of bagasse show better adsorption performance for HMs removal. Kinetic and isotherm studies of HMs adsorption equilibrium data over SCB show that both Langmuir and Freundlich adsorption isotherms (cooperative adsorption) as the main adsorption mechanism. In addition, SCB shows potential bio-adsorbent properties for the selective adsorption of target HMs based on their physicochemical properties and shows good repeatability in acid environments. It is believed that information on this review will shed light on the current and future prospects of raw and modified SCB for HMs adsorption removal capacity. Sugarcane bagasse shows a remarkable selectivity for HMs adsorption removals based on their physicochemical properties and shows good potential capability for future utilizations in real wastewaters of developing countries.

Published: January 2023

Abstract
The imbalance between water supply and demand highlights the vulnerability of many people and the prospect of an uncertain future for water supply. This work aims to compare the Urban Water Security Index (UWSI) with three other methodologies (percentage flow duration curve, Urban Water Sustainability Indicator, and accumulated data from the Drought Monitor) for the municipality of Guarabira, Paraíba, Brazil. The results show water security based on the amount of water in the study area. However, there is a need for proposals for assessing urban water security to be based on local sustainability. Water-sensitive planning is the solution to maintaining and conserving natural resources for future generations in the face of impacts, particularly climate change and population growth. The methodology applied in this work can contribute to the investigation of probable and specific causes of water insecurity and gives evidence of improvement in the concept of water security based on the urban metabolism of water.

Published: January 2023

Abstract:Viral diseases have a significant impact on human health, and three novel coronaviruses (CoV) have emerged during the 21st century. In this review, we have emphasized the potential of herbal substances with antiviral effects. Our investigation focused on the features and prospects of viral disease treatment, with a particular emphasis on proinflammatory cytokines. We conducted comprehensive searches of various databases, including Science Direct, CABI Direct, Web of Science, PubMed, and Scopus. Cytokine storm mechanisms play a crucial role in inducing a pro-inflammatory response by triggering the expression of cytokines and chemokines. This response leads to the recruitment of leukocytes and promotes antiviral effects, forming the first line of defense against viruses. Numerous studies have investigated the use of herbal medicine candidates as immunomodulators or antivirals. However, cytokine-storm-targeted therapy is recommended for patients with acute respiratory distress syndrome caused by SARS-CoV to survive severe pulmonary failure. Our reviews have demonstrated that herbal formulations could serve as alternative medicines and significantly reduce complicated viral infections. Furthermore, they hold promising potential as specific antiviral agents in experimental animal models.
