Both cleavage-stage and blastocyst-stage embryo transfer policieshave advantages and drawbacks.Potential advantages of blastocyst culture and transfer in human IVF include: i. synchronization of the embryo with the female tract leading to increasedimplantation rates; thereby, reducing the need for multipleembryo transfers, ii. assessment of viability of an embryobefore transfer. This can be ach...

In automated negotiation systems consisting of self-interested agents, contracts have traditionally been binding. Such contracts do not allow agents to eeciently accommodate future events. Game theory has proposed contingency contracts to solve this problem. Among computational agents, contingency contracts are often impractical due to large numbers of interdependent and unanticipated future ev...

Despite an impressive amount of effort and extensive research, our knowledge of parturition remains limited. Scientists have exhaustively investigated ‘‘the timing of birth’’; yet, we still have a limited understanding of the biologic mechanisms that control the events initiating delivery, and consequently, we lack tools to prevent these mechanisms from acting inappropriately. A multitude of fa...

Power dissipation of chips has been raising faster than the technology needed to economically cool them. Especially in the high performance arena. To get high efficiency heatsinks presently, extrusions are machined or entire heatsinks are machined with strategically arranged fins. These methods are not as effective in high component densities or cost sensitive units compared to newer, porosity ...

To the assessment of satellite’s capabilities during their progress can be added indices as mass, size and cost. At the final stages of their life-cycle development, owing to the progress in current space technologies, the idea for using small satellites is approved. The small satellites are specified as workefficient, productive and promising. The estimation and the choice ensue from economic ...

Electronic communications have become the most important kind of communications in business. However, trust, privacy and security have become the great challenges for business and governments around the globe. The Public Key Infrastructure (PKI) model tries to solve these issues and make the Internet more secure. This paper explains the main purposes of PKI and addresses some of the major issue...

in this study, the situation of iran, u.s and turkey's pistachio export is investigated. to this purpose, revealed comparative advantage (rca) index is calculated based on agricultural and total economy export, separately, then forecasted by using auto- regressive integrated moving average (arima) approached, for 2008-2013. the results show that considering both commodity baskets, turkey and ir...
