A gazelle optimization expedition for key term separated fractional nonlinear systems with application to electrically stimulated muscle modeling

Various real-time processes are effectively represented with a fractional nonlinear autoregressive exogenous (F-NARX) model where estimation of model parameters is considered as an essential task. In this study, a population-based gazelle optimization algorithm (GOA) inspired by the evolutionary characteristics of gazelle's is exploited for the parameter estimation of the key term-separated F-NARX system. The Grünwald-Letnikov derivative, a fractional order calculus operator is integrated to develop the F-NARX system from a conventional non-linear autoregressive system. The mean square error-based merit function is developed and the effectiveness of the GOA for the F-NARX system is analyzed in terms of speedy convergence, estimation accuracy, complexity and robustness for different noise scenarios. The extendibility of the GOA is assessed through the estimation of stiff parameters of the electrically stimulated muscle model (ESMM) required for rehabilitation of paralyzed muscles. The efficacy of the GOA is endorsed through Wilcoxon signed rank statistical test in comparison with recent counterparts of Runge Kutta optimization algorithm, Whale optimization algorithm, and Harris Hawks optimization algorithm.

The analysis of chasing returns strategy in equity funds

Most of the new investors, who are dominated by millennial investors, do not understand the basics of the capital market, so they have to suffer losses. Therefore, a strategy for investing in mutual funds is needed. This study aims to compare the performance of return-chasing investments with the buy-and-hold strategy in providing the best return to stock mutual fund investors. Beers (2020) states that “buy-and-hold” is a strategy in which investors buy stocks (or other types of securities, such as exchange-traded funds) and hold them for a long time regardless of market fluctuations. The data used is the net asset value of mutual funds which is then processed to obtain rank one based on annual returns. Simulations will be carried out to see the investment results of the two strategies and then the Wilcoxon signed-rank statistical test will be carried out on the profit/loss percentage to see the significance of the difference. The results of statistical tests show that there is no significant difference in investment returns between the chase return and buy and hold strategies. This result indicates the chasing return strategy provides much better investment returns than the buy-and-hold strategy for five periods on mutual fund instruments. The implication of this research for investors in using a chasing return strategy is that investors must use technical analysis, namely analyzing and finding out which mutual funds have the best prospects in that year.

After being given education, there was a significant increase in the respondents knowledge about self-medication with analgetic drugs, rising from 19.04% having good knowledge previously to 90.47% after the video education session, with the Wilcoxon test results indicating a significant difference between the pretest and post-test scores; the relatively low z-score (-3.794) and very low p-value (0.00) indicate that the ranking for the group with post-test scores is higher, signifying a significant improvement, thus post-test scores are better than pretest scores.

Assessing Variability in Reporting Severity of the Same Symptom (Fatigue) in the Context of Different Psychiatric Syndromes.

Objective The objective of this study is to examine the variability in the self-reported fatigue symptom severity in major depressive disorder (MDD) compared to generalized anxiety disorder (GAD). Methods A retrospective chart review was conducted of 100 patients evaluated for fatigue using depression and anxiety questionnaires. The study examined whether ratings of fatigue varied based on whether fatigue was being rated by the patient in the context of MDD vs. when fatigue was being rated by the same patient in the context of GAD. A related-sampleWilcoxon signed-rank test and Mann-Whitney U test were used to compare the median differences between depression and anxiety fatigue scores. The significance level used was 0.05. Results This study found a statistically significant difference in the median difference of the paired depression fatigue and anxiety fatigue scores (depression score - anxiety score) regardless of the order of administration (Wilcoxon signed-rank test statistic = 135.500, p-value =.008, N = 100 paired scores). Conclusion The study's conclusions show that although the symptom of fatigue is listed in the Diagnostic Statistical Manual 5 (DSM-5) criteria for MDD as well as GAD, it may be perceived by patients differently based on the context of the syndrome. This emphasizes the importance of considering the context of symptom reporting in patients with MDD and GAD to improve diagnostic methodologies and treatment strategies.

Health Education Effected Public Knowledge To Prevention Of Dengue Hemorrhagic Fever (DHF)

Problems The government's present approach to the challenges the DHF disease faces in Indonesia is insufficient. Though, in order to regulate the DHF condition, public support is essential. The fact that the general public does not participate in Mosquito Nest Eradication (PSN) initiatives shows how poorly understood and known DHF illness prevention is by the general population. Examine the impact of health education on the community's awareness of DHF prevention. Pretest-posttest design with a single group, pre-experimental investigation. The population of Village Sumberwuluh Subdistrict Dawarblandong Regency Mojokerto, which consists of 289 homes and is entirely under inquiry, was represented by one responder who was between the ages of 18 and 35 in each of the 289 households. This is a simple random sampling technique. 44 people comprise the huge sample. questionnaire-based instrument study using SAP. The results showed that 32 respondents (72.7%) had sufficient knowledge of DHF prevention before obtaining health education, and 23 respondents (52.3%), after getting health education, had sufficient knowledge of DHF prevention. Based on the Wilcoxon Signed Rank statistical test results, H1 is accepted and H0 is denied, which indicates that health education has an impact on community understanding on DHF prevention. When more data is acquired and health education is observed, a better understanding of DHF prevention is attained.

Analyzing The Effect Of BRICS On The Economic Growth Of Its Member

This study aims to analyze the effect of BRICS membership on the economic growth of its countries, specifically its impact on GDP growth rate and international trade. This study uses data on the GDP growth rate, exports, and imports from 1997 to 2021 for BRIC countries and from 2001 to 2021 for South Africa.

Cross Entropy Covariance Matrix Adaptation Evolution Strategy for Solving the Bi-Level Bidding Optimization Problem in Local Energy Markets

The increased penetration of renewables in power distribution networks has motivated significant interest in local energy systems. One of the main goals of local energy markets is to promote the participation of small consumers in energy transactions. Such transactions in local energy markets can be modeled as a bi-level optimization problem in which players (e.g., consumers, prosumers, or producers) at the upper level try to maximize their profits, whereas a market mechanism at the lower level maximizes the energy transacted. However, the strategic bidding in local energy markets is a complex NP-hard problem, due to its inherently nonlinear and discontinued characteristics. Thus, this article proposes the application of a hybridized Cross Entropy Covariance Matrix Adaptation Evolution Strategy (CE-CMAES) to tackle such a complex bi-level problem. The proposed CE-CMAES uses cross entropy for global exploration of search space and covariance matrix adaptation evolution strategy for local exploitation. The CE-CMAES prevents premature convergence while efficiently exploring the search space, thanks to its adaptive step-size mechanism. The performance of the algorithm is tested through simulation in a practical distribution system with renewable energy penetration. The comparative analysis shows that CE-CMAES achieves superior results concerning overall cost, mean fitness, and Ranking Index (i.e., a metric used in the competition for evaluation) compared with state-of-the-art algorithms. Wilcoxon Signed-Rank Statistical test is also applied, demonstrating that CE-CMAES results are statistically different and superior from the other tested algorithms.

Multi-Label Classification Using Binary Tree of Classifiers

This article proposes a binary tree of classifiers for multi-label classification that preserves label dependencies and handles class imbalance. At each node, the input data is strategically split into two subsets for its subsequent child nodes, keeping the label correlations intact. A novel approach of partitioning the data based on label-set proximity has also been proposed. Various data appropriate classifiers are trained to learn the binary partition at every internal node. The tree of classifiers grows iteratively depending on two parameters – multi-label entropy and sample cardinality, computed on the data at the current node. During training, the decision at any node is based on these parameters and the branching out is restricted, if deemed unnecessary. Specific classifiers at the leaf nodes perform the final classification task and assign appropriate label-sets to the unlabelled data. The proposed system aims to appropriately split the data and build the hierarchical structure such that the training and classification tasks become simpler. Also, the problem of class imbalance leads to the irregular splitting of data and excessive branching out of the tree which is handled through the novel use of suitable classifiers and parameters at the intermediate and leaf nodes. The proposed method has shown significant performance improvement on fourteen datasets against fourteen existing multi-label classifiers. Two-tailed Wilcoxon signed rank test statistics show that for <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$T_{Wilcoxon}(14,0.2)=31$</tex-math></inline-formula> the proposed method outperforms all the other comparison models.

Impact of COVID-19 on Consumption of Fish and Other Meats in NE Region of India

The COVID-19 pandemic has caused unprecedented stresses on food supply chain in the country, with bottlenecks in processing, transportation and logistics, as well as momentous shifts in consumption pattern and demand for fish and other meat. In this study, the impact of COVID-19 pandemic on consumption pattern of fish, chicken, egg, mutton, beef and pork, market availability and as well as prices in North Eastern Region of India was analysed in this study. The study based on primary data collected through online survey method for which a questionnaire framed in Google Form. The sample comprises of total 104 respondents. The Wilcoxon signed-rank test for repeated measure differences between before COVID-19 and during COVID-19 levels of consumption of fish and other non vegetarian food items and quality of fishes supplied during two periods were analysed. It was found that the reduction in consumption of fishes, chicken and beef, during COVID-19 pandemic, were statistically significant. Whereas, the Wilcoxon signed rank test statistics for mutton and pork turned out to be insignificant. During COVID-19 the consumption of local fishes increased due non availability and distortion of fish supply chain. The quality of fishes in terms of freshness, size and odour were also impacted. Due poor availability of fishes, prices of fish increased during COVID-19. The increase in fish prices and poor availability of fishes resulted to shift in purchase of processed fish products in the North Eastern Region in India. The disruption in transportation, logistics, lockdown, etc during COVID-19 impacted trade of fishes as well as its consumption in the region. Hence, efforts for increasing of local supply of fishes as well as the development of resilient supply chain with sufficient storage facilities is needed to cope up under such unprecedented situation.
