Aggregation operators of complex fuzzy Z-number sets and their applications in multi-criteria decision making
(Springer, 2024)Fuzzy sets (FSs) are a flexible and powerful tool for reasoning about uncertain situations that cannot be adequately expressed by classical sets. However, these sets fall short in two areas. The first is the reliability ... -
Alloying and phase transformation in CdS/CdSe bilayers annealed with or without CdCl2
(Elsevier Sci Ltd, 2019)The present paper studies the structural, compositional, morphological and optical properties of thin CdS/CdSe stacks annealed in an inert atmosphere or subjected to a CdCl2 treatment. the bilayer stacks were fabricated ... -
An almost orthosymmetric bilinear map
(2019)In this paper, as a generalization of the concept of pseudo-almost f-algebra, we deÖne a new concept of almost orthosymmetric bilinear map on a vector lattice and prove that the Arens triadjoint of a positive almost ... -
Altitude impacts body size but not age in the Asia Minor Thin-toed Gecko (Mediodactylus heterocercus)
(Canadian Science Publishing, 2022)Age and size-related life-history traits of animals are influenced by a variety of factors. In connection with climate, the effect of altitude on demographic parameters may differ among different populations of the same ... -
Altitude variation in the composition of essential oils, fatty acid methyl esters, and antimicrobial activities of two subspecies of primula vulgaris grown in Turkey
(Natural Product Incorporation, 2016)In this study, the changes caused by variation of altitude to the essential oils (EOs), fatty acid methyl esters (FAMEs), and antimicrobial activities of Primula vulgaris Huds. subsp. vulgaris (Pvv) and P. vulgaris Huds. ... -
Altitudinal effects on the life history of the Anatolian lizard (Apathya cappadocica, Werner 1902) from southeastern Anatolia, Turkey
(Tubitak Scientific & Technical Research Council Turkey, 2015)Altitudinal gradients are an important variable in testing the life history traits (e.g., longevity, age at maturity, and body size) of organisms. in this study, the life history traits of the Anatolian lizard Apathya ... -
Analysis of CeO2/SiO2 double-layer thin film stack with antireflection effect for silicon solar cells
(Springer, 2024)This study introduces CeO2/SiO2 double-layer film stacks and its antireflection coating effect. Optical properties were analyzed by spectrophotometer measurements; surface morphology and cross-sections were observed by ... -
Analysis of codon usage bias of exonuclease genes in invertebrate iridescent viruses
(Elsevier, 2024)Invertebrate iridescent viruses (IIVs) are double-stranded DNA viruses that belong to the Iridoviridae family. IIVs result diseases that vary in severity from subclinical to lethal in invertebrate hosts. Codon usage bias ... -
