Personalized advertising has grown drastically as new tracking technologies allow advertisers to monitor consumers’ online behavior and distribute advertisements accordingly, which has given rise to privacy concerns. The present study investigates the role of personality traits and data source in social media behavioral advertising’s value perception. Two online studies were conducted to examine how plasticity (shared variance of openness and extraversion) and data source (first party vs third-party) affect consumers’ privacy calculus and purchase intention respectively. The participants, all active social media users from the United States, were hired from Prolific.co. For the first study,... 

Currently, the HIFU (High Intensity Focused Ultrasound) therapy method is known as one of the most advanced surgical techniques in tumor ablation therapy. Simulation of the HIFU therapy in the case of appearance of bon barrier is essential in HIFU planning to improve the usefulness and efficiency of treatment in brain tumor cases. In this work, linear, thermoviscous equations are applied for simulation of phase correction array and steering method, after analysis of performance, these methods are used in a 3D human brain and skull model to estimate thermal ablation in case of using these methods. Results indicate that the maximum focal pressure of 1.42 and 1.65 MPa can be achieved for... 

Recently, nanotechnology has promised to create and/ or improve therapeutic methods which in turn remain minimum side effects by employing synergistic effects of nanostructures. However, a comprehensive understanding of the interactions between nanostructures and building blocks of the biological systems (cells) is essential to create innovative therapeutic methods and compound and also predict their behavior for upcoming applications. In this thesis for the first time, synergistic effects of graphene-nanobubbles in interactions with bacterial (as the simplest model) cells were investigated. Therefore, at the first step, production of nanobubbles (NBs) in the presence of two-dimensional...
