short-selling prohibition has been one of the primary assumptions of markowitz mean-variance model. solving markowitz quadratic model creates investment efficient frontier by considering only two return and budget constraints. in order to develop a more realistic portfolio selection model, in this paper, a new mathematical model is developed to allow short-selling under some practical constrain...

Introduction: The precision and time required for analysis of data in next-generation sequencing (NGS) depends on many factors including the tools utilized for alignment, variant calling, annotation and filtering of variants, personnel expertise in data analysis and interpretation, and computational capacity of the lab and its optimization is a challenging task.  Method: An application software...

Primary cilia extend like antennae from the surface of most eukaryotic cells into the environment, where they function in a variety of sensory roles. Recent studies reveal an intimate interplay between structural proteins of the centrosome and the formation of primary cilia, and provide new insight into the complex function of these fascinating organelles.
