Publication A Vibrational Spectroscopic Investigation of 2,2'-Bithiophene Using Experimental and DFT Methods(2023)Organic compounds like 2,2’-Bithiophene (with a synonym. 2,2'-bithienyl, 2,2'-dithienyl)- containing bis(dioxaborin) have drawn significant concern in the area of materials science because of their electron affinity and luminescent properties. With this motivation, we have been concentrating on the properties and functions of 2,2'-Bithiophene.Publication Multi-objective location-distribution optimization in blood supply chain: an application in Turkiye(2024-11-15) Altunoğlu, Burcu; Batur Sir, Gül DidemPurpose Blood donors are crucial in maintaining the blood supply chain. This study aims to improve the location and distribution of blood donation centers by focusing on two main objectives: minimizing costs and maximizing quality. Minimizing costs includes setting up and transporting blood efficiently while maximizing quality to ensure that blood products are delivered to hospitals promptly and in the right quantities. Methods A multi-objective mathematical model is proposed to address the placement of both fixed and mobile blood donation centers. The first objective focuses on minimizing the costs of setting up centers and transporting blood. The second objective aims to maximize quality by ensuring timely deliveries and meeting hospitals’ blood demand. The model utilizes real-world traffic and blood donation data from urban settings to simulate its effectiveness and applicability in practice. The model uses the epsilon constraint method to optimize both objectives simultaneously. Results The model was tested in various scenarios, optimizing cost and quality separately. The algorithm determined the ideal locations for blood donation centers to meet demand by exploring different options. It also accounted for factors that reduce quality, such as delayed deliveries and product returns, and showed that these issues could be minimized. Conclusion This study highlights the need to balance cost and quality when determining the locations of blood donation centers. Using the epsilon constraint method, the model successfully optimized both objectives, offering valuable insights for improving the efficiency and effectiveness of blood donation operations.Publication The Use of Machine Learning Approaches for the Diagnosis of Acute Appendicitis(2020) Akmese OF; Akmese OF, Dogan G, Kor H, Erbay H, Demir E.Publication A new triphenylphosphonium-conjugated amphipathic cationic peptide with improved cell-penetrating and ROS-targeting properties(2022) Ishkaeva RA; Ishkaeva RA, Salakhieva DV, Garifullin R, Alshadidi R, Laikov AV, Yergeshov AA, Kamalov MI, Abdullin TI.Publication End-To-End Computerized Diagnosis of Spondylolisthesis Using Only Lumbar X-rays(2021) Varçýn F; Varçýn F, Erbay H, Çetin E, Çetin Ý, Kültür T.Publication Fractal-Fractional Mathematical Model Addressing the Situation of Corona Virus in Pakistan(2020) Shah K; Shah K, Arfan M, Mahariq I, Ahmadian A, Salahshour S, Ferrara M.
