Mindfulness skills, psychological flexibility and psychological symptoms were compared among 58 physically less active and 50 physically active adults who were recruited and classified based on their self-reported physical activity. Additionally, this study evaluated the association of objectively measured physical activity with psychological variables. Methods: Participants completed questionn...

One of the first steps to initiate a technology-related business is perceive factors that would help users accept technology. In this regard, different models have been introduced explain technology acceptance and determine users’ needs. These theories psychological origins involve comprehensively cognitive backgrounds which deal with components predict user’s behavior. Prediction behavior majo...

starting from two-dimensional (2d) equations of motion, discretized formulations for transient behavior of soil-structure interaction problems have been derived. two different dynamic infinite elements taking into account single and two-wave types are presented in transformed space. by coupling the infinite elements with standard finite elements, an ordinary finite element procedure is used for...

Background: Dental students who are at clinical or educational stage, are under environmental stress. The cumulative effect of clinical and educational stressors may also have negatively impact performance of clinical education in the long term and lead to mental and physical disorders. Our aim was to recognize and compare the stressful factors of dental environment among the students of clinic...

Sequential decision making from experience, or reinforcement learning (RL), is a paradigm that is well-suited for agents seeking to optimize longterm gain as they carry out sensing, decision, and action in an unknown environment. RL tasks are commonly formulated as Markov Decision Problems (MDPs). Learning in finite MDPs enjoys several desirable properties, such as convergence, sample-efficienc...

Abstract—Punching shear failure is usually the governing failure mode of flat plate structures. Punching failure is brittle in nature which induces more vulnerability to this type of structure. In the present study, a 3D finite element model of a flat plate with low reinforcement ratio and without any transverse reinforcement has been developed. Punching shear stress and the deflection data wer...
