Research ArticleOpen accessIn the keywordsHoax Classification Corona Virus (COVID-19) News in Indonesian using the Support Vector Machine (SVM) MethodWiranto Herry Utomo, Karno Juni PrayogaThe development of information technology more widely, rapidly and quickly provide convenience to the public in access information. Internet is a container or online media makes the information hasn’t been verified or proved to be true which is rapidly spreading in the community. The purpose of this study is to facilitate in determining the hoax news or facts about corona … …Journal of Computer Science, Vol. 17, Issue 8 · 13 Oct 2021 · 6,795 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsTHE VOCALIZATION MECHANISM OF THE FLORIDA MANATEE (TRICHECHUS MANATUS LATIROSTRIS)Charles J. Grossman, Richard E. Hamilton, Martine De Wit et al.The mechanism by which Florida manatees produce vocalizations is unknown. Anatomically, the laryngeal region in manatees lacks clearly defined vocal folds. Initially we developed a method to visualize the entire manatee upper respiratory system. We then forced air through fresh necropsied manatee larynxes and generated artificial vocalizations which closely duplicated the normal vocalizations produced by live manatees, both in fundamental … …OnLine Journal of Biological Sciences, Vol. 14, Issue 2 · 25 Jun 2014 · 8,457 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsAnatomy of the Gross Intestine of the Capybara (Hydrochoerus Hydrochaeris)Noelia Vazquez, Rafael Senos, William PérezProblem statement: The anatomy of the gross intestine and its mesentery of the capybara (Hydrochoerus hydrochaeris) have not been described completely. Approach: In the present study, eight adult capybaras were studied using gross dissection. Results: The cecum was the largest part of the intestine and was divided into base, body and apex. The cecocolic fold joined the cecum to the … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 2 · 28 Jul 2012 · 9,202 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAdaptive Cross-Validation Under Concept Drift for Time Series ForecastingKunjira Kingphai, Prapakorn Kanjina, Kamol Sanittham, Wacharong WongsanurakTime-series forecasting often involves non-stationary data, making i.i.d. validation unreliable and fixed-window protocols vulnerable to leakage and biased error estimates. We propose Adaptive Time-Series Cross-Validation (ATSCV), a drift-aware evaluation framework that uses statistical change-point detection to partition each series into contiguous, approximately stationary regimes, followed by forward-chaining folds that respect those boundaries. By aligning train–validation splits with distributional changes (with … …Journal of Computer Science, Vol. 22, Issue 7 · 7 Jul 2026 · 1,488 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparative Analysis of Fraud Detection Methods in Banking Using Machine Learning TechniquesYoussef Tounsi, Ennouri TaziFraud detection in banking requires algorithms that balance classification performance, computational efficiency, and regulatory interpretability, criteria that are rarely benchmarked together. We present a comprehensive evaluation of nine machine learning approaches (Logistic Regression, Decision Tree, Random Forest, SVM, SGD, XGBoost, CatBoost, LightGBM, and MLP) across three datasets differing in size, imbalance severity, and feature type (synthetic, real-world PCA-anonymized, and large-scale … …Journal of Computer Science, Vol. 22, Issue 6 · 22 Jun 2026 · 1,341 accessesView PDF Cite

Review ArticleOpen accessIn the abstractCardiolipin in Pathology: Implications in AtherosclerosisAnastasia Vladimirovna Poznyak, Vasily Nikolaevich Sukhorukov, Anton Yuvenalievich Postnov et al.Mitochondria are cell organelles whose main role is to generate the energy needed for cell biochemical reactions via oxidative phosphorylation. Cardiolipin is a phospholipid that is present in the inner mitochondrial membrane and other energy-transducing membranes. Mitochondrial structure largely depends on cardiolipin, as it is involved in the biogenesis of mitochondrial cristae, folds in the inner mitochondrial membrane designed to … …OnLine Journal of Biological Sciences, Vol. 23, Issue 4 · 23 Sep 2023 · 4,792 accessesView PDF Cite

Research ArticleOpen accessIn the abstractProtective Role of Chichorium intybus Extract Against Renal Toxicity Induced by Magnetite Silver Nanoparticles in Male RatsDoha M. Beltagy, Ehab Tousson, Nabiha I Abdo, Batoul M. IzzularabMagnetite silver nanoparticles (Fe3O4/AgNPs) symbolize a new candidate in several industrial and biological products for their activities, simple preparation and low synthesis costs. Many studies recommended the usage of Fe3O4/AgNPs to overcome lacking biocompatibility of AgNPs inside the body. However, Fe3O4/AgNPs also has toxic effects on kidney tissues. In this study, AgNPs was synthesized on the surface of magnetic nanoparticles … …OnLine Journal of Biological Sciences, Vol. 21, Issue 3 · 15 Sep 2021 · 6,318 accessesView PDF Cite

EditorialOpen accessIn the abstractEditorial Commentary: Challenge of Non–AIDS-Defining Cancers (NADCs), Focusing on Trans Activation Response Element (TAR) RNA Embedding ExosomesLechuang Chen, Ge JinGlobally, 37.9 million people were living with HIV at the end of 2018 (Organization, 2018). Cancer is a major cause of mortality and morbidity in AIDS patients and chronically HIV-infected people. With the aid of combination Antiretroviral Therapy (ART), people living with HIV (PLWH) have a longer life span. However, because the virus is not completely eradicated, PLWH under antiretroviral … …American Journal of Immunology, Vol. 15, Issue 1 · 28 Nov 2019 · 6,657 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEnhanced Fatty Acid Production in Escherichia coli by Over-Expression of NADPH Generating EnzymesYuanda Song, Yong Q. Chen, Haiqin Chen et al.NADPH is an essential factor for Fatty Acid (FA) biosynthesis. The effect of NADPH generating enzymes [NADP+-dependent malic enzyme (NADP-ME), NADP+-dependent isocitrate dehydrogenase (NADP-IDH), Glucose 6-Phosphate Dehydrogenase (GPD) and 6-Phosphogluconate Dehydrogenase (PGD)] on FA biosynthesis was investigated in an engineered Escherichia coli BL21 △fadE/pTE.
