Push technologies are rapidly moving toward autonomous and evolutionary intelligent agents for seeking, organizing, and creating information via the Web and other pervasive and innovative information technologies. We describe and define autonomous and evolutionary agents designed for push technologies. Memes, which are messages one agent broadcasts to another, causing the agent to evolve are in...

The profiles of narrow lattice solitons are calculated analytically using perturbation analysis. A stability analysis shows that solitons centered at a lattice (potential) maximum are unstable, as they drift toward the nearest lattice minimum. This instability can, however, be so weak that the soliton is “mathematically unstable” but “physically stable”. Stability of solitons centered at a latt...

humanities is the oldest area of study that revolves around the study of human beings, what makes us human and our historical development, and what we are expected to do. this discipline deals with human behavior, human nature, social and political values. humanities comprise of various disciplines that include art, history, law, linguistics, philosophy, religious and ethics among others. all t...

Background: Nowadays, cardiovascular diseases (CVDs) are among the most common causes of mortalities worldwide. Parathyroid hormone (PTH) has an important role in the pathogenesis of CVDs. The aim of the current study was to compare serum PTH levels between patients with acute myocardial infarction (MI), unstable angina, and normal coronary function. Methods: This descriptive and analytic stud...

nowadays, hidden markov models are extensively utilized for modeling stochastic processes. these models help researchers establish and implement the desired theoretical foundations using markov algorithms such as forward one. however, using stability hypothesis and the mean statistic for determining the values of markov functions on unstable statistical data set has led to a significant reducti...

[Purpose] The purpose of this study was to determine the effect of hand position changes on electromyographic activity of shoulder stabilizers during push-up plus exercise (PUPE) performed on both stable and unstable surfaces. [Subjects] This study was performed on a cohort of 20 normal adults divided into an unstable surface group (USG) (n=10) and a stable surface group (SSG) (n=10). [Methods]...
