BACKGROUND Synthetic genomic approaches offer unique opportunities to use powerful yeast and Escherichia coli genetic systems to assemble and modify chromosome-sized molecules before returning the modified DNA to the target host. For example, the entire 1 Mb Mycoplasma mycoides chromosome can be stably maintained and manipulated in yeast before being transplanted back into recipient cells. We h...
Introduction: Cloning technology has been strengthened a long human desire for eternal life. The possibility of human cloning is the new challenges in medical education and medical ethics. The present study discussed the different perspectives in this field. Methods: This study is a review article. Related books and some database such as SID, Irandoc, Elsevier, PubMed, Magiran were searched us...
We investigate the role of symmetric quantum cloning machines (QCMs) in quantifying mutual incompatibility observables. Specifically, we identify a cloning-based measure whereby set observables maybe quantified terms how well uniform ensemble their eigenstates can be cloned via QCM. show that this new $\mathcal{Q}_{c}$ is {\it faithful} since it vanishes only for commuting prove an upper bound ...
We consider the problem of determining achievable region parameters for universal $1 \to 2$ asymmetric quantum cloning. Measuring cloning performance with figure merit singlet fraction, we show that physical is a union ellipses in plane. Equivalently, characterize parameter state compatibility two possibly different isotropic states, considering, first time, negative fractions.
In 1997, there was a report in Nature that announced the birth of Dolly the first cloned mammal in the world using nuclear transfer. After it, a lot of ethical and religious reactions were claimed against human cloning while no absolute opposition was presented against animal cloning. European :union: (EUROPA) as one of the most important and effective international organizations, has been play...
Human cloning is one of the latest and most complicated developments in the field of medical and genetic sciences that could fulfill man’s dream of eternal life. Scientists’ achievements in this respect, however, have brought about many concerns for thinkers, particularly ethics scholars. Human and animal cloning have been examined from different angles, but one basic aspect of human cloning ...
Cloning of the maize rough dwarf virus genome: molecular confirmation of the plant-reovirus classification scheme and identification of two large nonoverlapping coding domains within a single genomic segment.

We address the problem of imitation learning with multi-modal demonstrations. Instead attempting to learn all modes, we argue that in many tasks it is sufficient imitate any one them. show state-of-the-art methods such as GAIL and behavior cloning, due their choice loss function, often incorrectly interpolate between modes. Our key insight minimize right divergence learner expert state-action d...
