        Optimal Control of Steel Structures by Improved Particle Swarm

        Saeid Aghajanian,Hadi Baghi,Fereidoun Amini,Masoud Zabihi Samani 한국강구조학회 2014 International Journal of Steel Structures Vol.14 No.2

        Active control is one of the modern approaches in seismic design of steel structures. Recently, induced by economicconsiderations, especially high expenses of control systems, optimality has become an important issue. In this paper an activesystem is used to control a steel structure’s displacements by a simplified pole assignment method. To optimize the number,the locations, and the total driving force of the required actuators, an improved particle swarm algorithm is presented focusingon the parameters of the velocity equation. A Geographical neighborhood topology and an adaptive inertia weight are used toimprove the standard PSO algorithm. In addition to the local and global best solutions, the positions of the best particles inthe geographical neighborhood are mathematically represented in an additional term. The performance of the proposedalgorithm is compared with the traditional Genetic Algorithm (GA) and the standard particle swarm considering the optimalcontrol of a 12-story steel structure as a numerical example. High capabilities of the proposed method in terms of the controltarget, convergence rate, and accuracy are simultaneously clarified by the results.

        Bacteriophages: cancer diagnosis, treatment, and future prospects

        Abbaszadeh Faezeh,Leylabadlo Hamed Ebrahimzadeh,Alinezhad Farbod,Feizi Hadi,Mobed Ahmad,Baghbanijavid Shabnam,Baghi Hossein Bannazadeh 한국약제학회 2021 Journal of Pharmaceutical Investigation Vol.51 No.1

        Background Early diagnosis is one of the most important factors in cancer treatment. Unfortunately, despite remarkable advances in the diagnosis and treatment methods of cancers in recent years, these methods are far from being perfect and have significant limitations and disadvantages. High costs and unwanted damage to healthy cells are some of the most important challenges. Area covered With the advent of novel technologies, potentially advantageous methods are being studied actively. The use of bacteriophages is one of the modern methods for cancer diagnosis and treatment. In the present article, we will discuss the potential advantages and limitations regarding the use of bacteriophages in the diagnosis and treatment of malignancies. Expert opinion The use of bacteriophages is one of the more recent methods for cancer diagnosis and treatment. Due to the non-pathogenic nature of bacteriophages, their genetic engineering capability makes them a great option for therapeutic purposes. The exact potential of phages to be used in the diagnosis and treatment of cancer, will be determined with further research in the future.
