Research NotesOpen accessIn the abstractTime-Resolution of Climate Change Monitoring Volcanic Cycles, Stromboli, Ocean Floor Biota and Pandemics (?)Giovanni Pietro Gregori, Gabriele PaparoClimate change is an ongoing, poorly understood and disquieting challenge. The primary drivers are debated. Clear evidence is however suggestive of a time variation of the planetary release of endogenous energy. In fact, soil exhalation is an unprecedented challenge for humankind, as a phenomenon of this kind happens only every 27.40.05 Ma, while human history spans only the last 30,0000 … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 7 Sep 2021 · 6,258 accessesView PDFCite
Literature ReviewOpen accessIn the abstractDiagnostic Imaging of Gastrointestinal Tumours in Dogs and Cats: A ReviewFrancesco Simeoni, Francesca Del Signore, Rossella Terragni et al.Gastrointestinal tract tumours in dogs and cats are characterized by non-specific clinical presentation and laboratory abnormalities, but require fast identification, characterization and staging. Imaging techniques play a key role in the diagnostic process of these diseases in routine veterinary practice. Survey and contrast radiography may indicate primary or secondary signs of gastric or intestinal neoplasia such as a wall mass, … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 2 · 15 Apr 2020 · 9,839 accessesView PDFCite
Case ReportOpen accessIn the abstractAn Unusual Case of Acute Abdomen: Intestinal Ascariasis: Case Report and Literature ReviewAshaur Azhar, Rebecca Ann LillisAscariasis is uncommon in United States of America but can be seen in immigrants and travelers. It can present with intestinal complications. We present a case of acute suppurative appendicitis with bowel perforation. Interestingly and unexpected, worms were palpated in the intestine in the operating room. Later, an adult Ascaris worm was identified in nasogastric tube canister. During hospitalization, a … …American Journal of Infectious Diseases, Vol. 15, Issue 4 · 14 Nov 2019 · 6,962 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of an Intelligent Electronic Prescription Ontology Using Open Source Tools: A Botswana Case StudyTshiamo Sigwele, Eunice Okon, Tshepiso Mokgetse, Onkemetse TshenyegoHealthcare interoperability in Botswana is hindered by fragmented information exchange across public and private providers, resulting in prescription conflicts, duplicated treatment, and delayed care. In prior work, we developed the Intelligent Electronic Prescription Ontology (IEPO), an open-source OWL 2 ontology for semantically standardized prescription data exchange. Although IEPO was previously validated using competency question-driven metrics (recall, precision, and F1-score), those … …Journal of Computer Science, Vol. 22, Issue 10 · 29 Sep 2026 · 513 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Adaptive Detail Preserving Modified Progressive Pca Thresholding Based Image DenoisingN. Anilkumar, S. Radhakrishnan, Shaik Syed Basha et al.Radiologists use medical imaging tools to assess the anatomy and function of interior organs. However, medical images are frequently distorted by various types of noise generated during the capture, transmission, and reconstruction operations, which can dramatically reduce image quality and hide critical diagnostic features. As a result, developing effective denoising algorithms that suppress noise while maintaining structural information remains a … …Journal of Computer Science, Vol. 22, Issue 8 · 8 Sep 2026 · 536 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing Supervised Classification Algorithms for Mangrove Detection and Differentiation from Other Forest Types in Paiton District, Probolinggo RegencyKaruniawan Puji Wicaksono, Fathor Rohman, Yasushi MitsudaRemote sensing provides an effective approach for monitoring forest cover dynamics, yet distinguishing mangroves from other forest types remains challenging in heterogeneous coastal landscapes. This study compares six supervised classification algorithms: Linear Discriminant Analysis (LDA), Quadratic Discriminant Analysis (QDA), Mixture Discriminant Analysis (MDA), Support Vector Machine (SVM), Random Forest (RF), and eXtreme Gradient Boosting (XGBoost) for mangrove detection in Paiton, … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 1 Sep 2026 · 849 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Aspiration for Becoming a Celebrity or Hero: A Comparative Study Across the United States, Iran, and AfghanistanJeremy Grabbe, Amir Mostafa AhadiThe present study examined cross-cultural differences in the desire to become a celebrity or a hero across samples from the United States, Iran, and Afghanistan. Building on prior findings that individuals in the United States may prefer heroism over celebrity status, the current study explored whether this pattern generalizes across differing cultural contexts. Participants completed the Celebrity Attitude Scale Brief … …Current Research in Psychology, Vol. 12, Issue 1 · 15 Aug 2026 · 1,213 accessesView PDFCite
Research ArticleOpen accessIn the abstractMechanical Scarification and Sucrose Priming Overcome Physical Dormancy in Caesalpinia spinosa (Tara) Seeds from the Peruvian HighlandsWilfredo Ruiz-Camacho, Ítalo Maldonado Ramirez, Juan Eduardo Suarez Rivadeneira et al.Caesalpinia spinose (tara) is a leguminous tree native to the Peruvian Andes-Amazon region, valued for soil restoration and high tannin content. However, its large-scale propagation is constrained by physical seed dormancy caused by a hard and impermeable seed coat. This study evaluated six pre-germination treatments to break dormancy and enhance early seedling development under local agroclimatic conditions in Magdalena District, … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 12 Aug 2026 · 1,211 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Zein-Fucoidan Nanoparticles Loaded with Curcumin on the Maillard Reaction Between Casein and LactoseShiyang Li, Yufan Liu, Yuanda Song et al.The influence of curcumin-encapsulated Zein-Fucoidan Nanoparticles (CZFNPs) on the formation of Maillard reaction products (MRP) at the early, intermediate, and advanced stages in a casein-lactose (CN-Le) reaction system was systematically studied. As controls, the effects of Zein-Fucoidan Nanoparticles (ZFNPs) and free Curcumin (Cur) were also evaluated. The results showed that CZFNPs effectively inhibited the formation of fructosamine, Glyoxal (GO), as … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 30 Jul 2026 · 612 accessesView PDFCite
Research ArticleOpen accessIn the abstractCA-LIME: A Collinearity-Aware LIME Framework for Reliable and Interpretable Explanations in Healthcare AIIdris Khan, Sachin BhoiteIn clinical tabular models, correlated biomarkers can make local explanations unstable even when predictive performance appears acceptable. This paper presents CA-LIME, a collinearity-aware extension of LIME built to address that failure mode directly. Five variations of CA-LIME Vanilla reference, VIF, PCA back projection, Ridge, and ElasticNet allow us to investigate how various correlation-control strategies alter explanation behavior.
