Research ArticleOpen accessEvery word in the titleModified U-Net With VGG11-BN Encoder and Frost Filter Based Pre-Processing for Copy Move Forgery LocalizationAshutosh Pandey, Niranjan Lal, Ashish Kumar ChakravertiCopy-move forgery is a widely used forgery method in digital image forensics, which involves copying and pasting a part of an image into another part of the image to hide or duplicate the visual information. This makes it difficult to detect such manipulations, particularly when the regions are subjected to geometric and photometric transformations. A Frost Filter-Enhanced Encoder-Decoder U-Net is … …Journal of Computer Science, Vol. 22, Issue 10 · 6 Oct 2026 · 457 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffectual Deep Learning Based Digital Image Forgery Detection Model Using Ameliorate CNN, VGG 16 and VGG 19 for Copy Move and Image Splicing Classification With Enhanced PerformancePreeti Dhiman, Usha ChauhanIn this research, a pioneer passive approach for detecting and localizing tampering in images is proposed. In the past, image forgeries have created a huge impact in the world. Developments of various image processing technologies made it easier to tamper images with the objective to cover up or hide a significant feature in an image. In some situation, such as … …Journal of Computer Science, Vol. 22, Issue 10 · 3 Oct 2026 · 568 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCulture and Religion Meaning-Making Coping Strategies in Wartime: Insights from a Qualitative Study on the Coping Experiences of UkrainiansFereshteh Ahmadi, Nataliia Melnyk et al.This study explores how Ukrainians use religious and spiritual meaning-making coping strategies during the ongoing war, shaped by cultural traditions, historical experiences, and personal circumstances. Its aim is to deepen understanding of culturally relevant resilience mechanisms in extreme adversity. Using a qualitative design, 67 semi-structured interviews were conducted across diverse Ukrainian regions between January 2024 and June 2025. Participants varied … …Journal of Social Sciences, Vol. 22, Issue 1 · 8 May 2026 · 2,435 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBiosynthesis and Evaluation of Zinc, Copper, and Methionine Feed Supplements Using Saccharomyces cerevisiae on Duck Performance in Minimal Water SystemsHendi Setiyatwan, Muhammad Rifqi IsmirajOptimizing duck performance under minimal water conditions is essential for sustainable poultry farming. Biosynthesizing essential feed supplements like Zinc (Zn), Copper (Cu), and methionine using Saccharomyces cerevisiae presents a promising method to enhance growth and meat quality. This study developed a biosynthesis method for Zn, Cu, and methionine supplements using S. cerevisiae and evaluated their effects on duck performance. In … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 1 · 11 Feb 2025 · 4,405 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMultivariate Option Pricing with Gaussian Mixture Distributions and Mixed CopulasJimbo Henri Claver, Tatanfack Emerson, Shu FelixRecently, it has been reported that the hypothesis proposed by the classical black scholes model to price multivariate options in finance were unrealistic, as such, several other methods have been introduced over the last decades including the copulas methods which uses copulas functions to model the dependence structure of underlying assets. However, the previous work did not take into account … …Journal of Mathematics and Statistics, Vol. 19, Issue 1 · 3 Apr 2023 · 6,511 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExpression of Metallothionein-Like Protein 2B Gene Induced by Different Concentrations of Copper in White Spruce (Picea glauca)Megan McKergow, Kabwe NkongoloThe alterations to the expressions of metal transporter genes can induce metal ion uptake to maintain cell homeostasis when metal concentrations are low. Metallothioneins (MTs) are a class of low molecular mass (4-8 kDa), cysteine (Cys)-rich proteins that can bind metals via the thiol groups of their Cys residues. Studies on MT gene expressions in higher plants, such as conifers, … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 4 · 25 Dec 2022 · 5,118 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGeochemical and Petrology Properties of Zafarghand Index and Kahang Deposit of Porphyry Copper-MolybdenumMohsen Dehghanipoodeh, Hooshang Asadi Haroni, Mahin Mansouri Esfahani et al.The probability of the occurrence of porphyry copper ore associated with subduction zone of the Neo-Tethys ocean and volcanic arc of Iran (Urumieh-Dokhtar) justifies the necessity of exploration and prospection of this type of ore in Iran. Zafarghand index and Kahang deposit of porphyry copper-molybdenum located in Isfahan province, center of Iran using Satellite data interpretations were discovered in the … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 19 Nov 2020 · 6,796 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEnhancing of Copper (II) Adsorption Efficiency by Mixing Plantain and Orange Peelings as Bio-Sorbent SupportSamomssa Inna, Ebelle Epoi Charlotte Alvine, Adjia Zangue Henriette, Sieliechi JosephThe present study focuses on the valorization of plantain and orange peels in the field of water treatment contaminated by heavy metals, especially copper (II). To carry out this study, simplex centroid mixture design was used to determine best mixture from plantain and orange peelings through iodine number, specific surface area and point of zero charge.

Research ArticleOpen accessEvery word in the titleCopper (I)-Nicotinate Promotes Gene Expression of CYPs that Produce M1 and Q1 in Aflatoxicosed RatsMohammed Salah, Laila Mostafa, Tahia H. Saleem et al.Aflatoxin-contaminated food poses a serious risk to both human and animal health. Copper (1)-nicotinate (Cu+-nicotinate) complex potentiated the prophylactic effect against chronic aflatoxicosis in the experimental animals through the synthesis of less toxic metabolites M1 and Q1 which are easily excreted in urine. To investigate the action of the safety Cu+-nicotinate complex on gene expression of Cytochrome 450 (CYP450) system, … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 28 Jan 2020 · 8,152 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReprocess of Copper from Worn Printed Circuit BoardsSwarnambiga A.K., M. Vidya Kalaivani, Sarah Sathyawathi, T.S. Ramyaa LakshmiThe objective of the study is to reuse printed circuit boards which are mainly made of copper. Most top down and bottom up approaches for the synthesis of Copper nanoparticles (CuNPs) needs pure copper (II) sulfate or any other copper salts as a raw material.
