Probing the Reasons Why the Goals of the Fifth Economic, Social and Cultural Development Plan Have not Been Realized in the Cooperative Sector in Iran

The cooperative sector is one of the three main components of the Islamic Republic of Iran’s economic system. Based on the top policies of Article 44 of the Constitution, its share of the national economy is expected to reach 25% by the end of the Fifth Development Plan. However, only 7% of this share has so far been realized. This study aims at discovering the reasons, backgrounds, processes a...

Simple explanation on why QKD keys have not been proved secure

A simple counter-example is given on the prevalent interpretation of the trace distance criterion as failure probability in quantum key distribution protocols. A summary of its ramifications is listed. Quantum key distribution (QKD) is widely perceived to have been proved “secure” in various protocols, in contrast to conventional encryption methods. In particular, perfect security is taken to h...

Why have parasites promoting mating success been observed so rarely?

Host manipulation by sexually transmitted parasites which increases host mating rate and thus parasite transmission rate has long been viewed as a plausible parasite adaptation. However, empirical evidence for it is rare. Here, using an adaptive dynamics approach to evolution, we explore conditions under which such disease-induced mating enhancement is (or is not) likely to occur. We find that ...

Why has Not There been More Research of Concern?

Amid the renewed concern in the last several years about the potential for life science research to facilitate the spread of disease, a central plank of the policy response has been to enact processes for assessing the risks and benefits of "research of concern." The recent controversy regarding a proposed redaction of work on the modification of a H5N1 avian influenza virus is perhaps the most...
