It is a cause of death of many women across the world. As a part of treatment, a woman might have to go through painful surgery and chemotherapy that may further lead to severe side effects. However, it is possible to cure it if it is diagnosed in the initial stage. Recently, many researchers have leveraged machine learning (ML) techniques to classify breast cancer. However, these methods are computationally expensive and prone to the overfitting problem. A simple single-layer neural network, i.e., functional link artificial neural network (FLANN), is proposed to overcome this problem. Further, the F-score is used to reduce the issue of overfitting by selecting features having a higher significance level. In this paper, FLANN is proposed to classify breast cancer using Wisconsin Breast Cancer Dataset (WBCD) (with 699 samples) and Wisconsin Diagnostic Breast Cancer (WDBC) (with 569 samples) datasets.

Numerous researches till now shows that the efficiency of wave energy extraction depends highly on the shape and design of the device and also its interaction with the energy resource. This paper proposes a particular design of a floating buoy point absorber wave energy converter considering its feasibility in the geographical condition of the coastal region in Bangladesh. After discussing the design algorithm and its functionality, a procedure has been given to evaluate the wave energy converter energy production quantitatively with the help of WEC-Sim library on MATLAB software. As the ocean waves are irregular and the wave height and period varies significantly from wave to wave, the generated power is highly variable which imposes a big challenge in harnessing ocean wave energy for electricity generation. In this study, a method has been proposed to generate steady sinusoidal voltage from the variable electrical power produced from irregular ocean waves. Next, the available data on wave characteristics of several coastal regions have been examined and checked against the proposed design. Finally, analyzing the simulation results and considering the possibilities and limitations of energy production, some recommendations have been given on where such devices can be installed.

We found that macroeconomic and institutional variables are valuable indicators for forecasting crises. Our results show that a low level of export growth, current account surplus/GDP, GDP growth, a high level of real exchange rate growth, import growth, and short-term debt/reserves can explain the advent of a possible currency crisis. We found that a poor law and order scenario and high external conflict can lead to a currency crisis. Additional findings include high government stability and the absence of internal conflict, which contribute to an absence of democracy, ultimately leading to a currency crisis. The policy-makers can consider taking the effective pre-emptive actions to prevent the currency crises occurring in the future.

This study aims to quantify the association of dietary, behavioural and lifestyle risk factors and comorbidities on the magnitude and distribution of disability burden among cancer patients in Australia. METHODS This study comprised a sample of 2283 cancer patients drawn from the latest nationwide Australian National Health Survey conducted in 2017-18. Negative binomial regression models were used to estimate the incidence rate ratio (IRR) of the number of disabilities and its associations. RESULTS Forty-five percent of cancer patients experienced at least one disability. The magnitude of disability was significantly associated with sugar-sweetened drink consumption ≥ 3 days per week (IRR= 1.12, 95% CI: 1.02-1.26), a lack of physical activity (IRR = 1.69, 1.38-2.07), frequent or regular alcohol consumption (IRR = 1.95, 1.84-2.08), poor health status (IRR = 1.99, 1.78-2.24) and the presence of five or more chronic comorbid conditions (IRR = 3.59, 2.90-4.46). Cancer patients who consumed vegetables at least two or more times per day had a 10% lower risk of disability burden (IRR = 0.90, 0.82-0.99). CONCLUSIONS This study shows the association of diet, behavioural, and lifestyle risk factors on the degree of disability burden among cancer patients, highlighting the need for bold and effective policies. The findings will inform the implementation of evidence-based lifestyle interventions and offer a foundation for evaluating their influence on cancer survivors' health.

The contribution of Treg deficiency in the etiology of systemic lupus erythematosus (SLE) is still being debated. The aim of the present study is to evaluate the percentage of circulating CD4+CD25+Foxp3+ Treg cells in a cohort of Egyptian SLE patients and to correlate this value with the activity and damage index of these patients. Methods 50 female patients with SLE together with an equal number of age- and sex-matched healthy controls were enrolled in the study. Flow cytometric determination of peripheral Treg cells was carried out for all participants by detecting the percentage of CD4+CD25+Foxp3+ cells to compare cases with the control group. Disease activity was assessed using the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K), while disease damage was assesse...

In this study, we examined the impact of child marriage on MHCS utilisation among the prime reproductive aged women of five South Asian countries Afghanistan, Bangladesh, India, Nepal and Pakistan. Data for this study are extracted from the most recent Demographic and Health Surveys. The effect of child marriage on the use of MHCS was assessed by the multivariate logistic regression analysis. Findings reveal that in the South Asian region, the prevalence of child marriage is more common in Bangladesh, followed by Afghanistan, Nepal, India and Pakistan. Child marriage significantly (p< .01) deters the usage of MHCS - at least once antenatal care (ANC) visit, at least four ANC visit, Institutional delivery and seeking assistance from skilled birth assistance (SBA), though the effect size was somewhat different across the countries. Findings stipulate to remain girls in schooling more and the marriage acts of the countries should be enacted properly to diminish child marriage not only for increasing MHCS use, also for individual wellbeing and overall development of each country.Impact StatementWhat is already known on this subject? Child marriage in South Asian countries is commonplace despite substantial improvements of socioeconomic status. Although child marriage have many adverse reproductive and health outcomes, empirical evidence and systematic studies, particularly the association of child marriage with the usage of Maternal Health Care Services (MHCS) in the South Asian women are few.What do the results of this study add? Findings of this study affirm that prevalence of child marriage in South Asian region is still common. Although every country has set out minimum age at first marriage by acts, the acts are poorly followed, which adversely impacts the usage of MHCS among married women.What are the implications of these findings for clinical practice and/or future research? The study findings provide important insights of the consequence of child marriage on the skilled MHCS utilisation. The marriage acts of the countries should be enacted properly to restrict child marriage not only for increasing MHCS, also for individual wellbeing and overall development of each country. Study has important implications for planners, organisation managers and policy makers.

The Forced Vital Capacity (FVC) of the patient is an interesting measure to investigate this disease to have the prognosis of the disease. This paper proposes a deep learning-based FVC-Net architecture to predict the progression of the disease from the patient’s computed tomography (CT) scan and the patient’s metadata. The input to the model combines the image score generated based on the degree of honeycombing for a patient identified based on segmented lung images and the metadata. This input is then fed to a 3-layer net to obtain the final output. The performance of the proposed FVC-Net model is compared with various contemporary state-of-the-art deep learning-based models, which are available on a cohort from the pulmonary fibrosis progression dataset. The model showcased significant improvement in the performance over oth...

This study is based on the assumptions that there is the rationality of Bangladesh to join in BRICS for adapting the global economic Insurgency. The type of the study is descriptive and the sources of data are secondary. In this paper we have analyzed and compared the main economic indicators of Bangladesh and BRICS countries – like GDP, FDI, Inflation rate, unemployment rate, Export and Import etc. The result of the study concludes the dominant role of BRICS countries in global economy and the position of Bangladesh to be a member of BRICS for adapting the global economic insurgency.

Museums in Bangladesh may also contribute positively to the country's economic development. This study investigates individuals' visit behavior to museums in Bangladesh and tries to identify dominant influential factors. Total fifty four (54) attributes have been taken into consideration in designing questionnaire for the study. A questionnaire survey method has been used with 220 visitors and response rate of 91 percent. Initially an exploratory factor analysis has been directed using SPSS (version 18.0). The key consequence of the analysis presents total seven (7) explanatory factors. The factors are cultural values, archeological, motivational, aesthetic, services, learning and promotional. One of the most dominant factors is cultural values. We have identified service factor as a new one and also provided strategies for museum marketing. The museum marketing strategies which have three parts namely promotional, service operation and service delivery strategies that ultimately help to understand and inform the visitors, satisfy visitors' motivational, psychological needs, facilitate learning and ensure how the services and experiences can be provided in more enjoyable manner to visitors. The findings of the study will help to ensure visitors' satisfaction efficiently for sustainable development of the museums as well as tourism sector of Bangladesh.

Bus service is the mostly used transport service for most of the people in Dhaka. Unfortunately the bus service is yet to be automated. For the citizen of Dhaka and particularly for the new comers, it becomes very difficult to select the right transport (bus) to travel from one place to another place. Sometimes, some routes are suddenly become blocked due to some unavoidable reasons. Hence, developing an intelligent transport system is a time-demanding issue for Dhaka City. In this paper, we propose and design an intelligent transport system targeting the public buses (useable for other transports as well) of Dhaka city. Our system provides dynamic route for the passengers or drivers as well as for the administrators. The traffic control people or the Bangladesh Road Transport Authority (BRTA) can work as the administrators. We have developed an android based application for our proposed transport system. The application has two modules: one for the passengers or drivers and one for the administrators. By using the first module the passengers can see including others name of the buses, travel distance, travel cost, and rout map. The second module is used by the administrators for adding, removing or diverting routes whenever needed.
