Food system regulators often decide whether to ban existing practices or approve new technologies without conclusive scientific evidence on possible damage and knowing that resolution is likely in the future. In a model with three decision points and stochastic resolution of uncertainty, we study interactions between expected losses due to regulation and information availability when a regulato...

Wireless sensor network has undergone tremendous development in the last one decade. The reduced size of the sensors coupled with enhanced capability made the dream of unobtrusive monitoring closer to reality. Sensors are cheaper and readily available in the market in these days. These sensors, when deployed on the human body, forms a Body Area Network (BAN) that can detect and forward various ...

How does the CITES trade ban on international trade in elephant ivory affect the incentives to poach African elephants? In this commentary, the major effects of a trade ban on poaching incentives are captured in a simple static model of world ivory supply and demand. It is shown that a trade ban has ambiguous effects on poaching incentives. Although the ban reduces international ivory demand, o...

Advanced metering infrastructure (AMI) is a key part of the smart grid; thus, one of the most important concerns is to offer a secure mutual authentication.  This study focuses on communication between a smart meter and a server on the utility side. Hence, a mutual authentication mechanism in AMI is presented based on the elliptic curve cryptography (ECC) and one time signature (OTS) consists o...

Smart grid concept is introduced to modify the power grid by utilizing new information and communication technology. Smart grid needs live power consumption monitoring to provide required services and for this issue, bi-directional communication is essential. Security and privacy are the most important requirements that should be provided in the communication. Because of the complex design of s...

QUESTION UNDER STUDY In the first year after implementation of a public smoking ban a significant decrease in the incidence of acute myocardial infarction (AMI) was observed in Graubünden. In the present study we analyzed the incidence of AMI in the second year of the ban. In addition, we investigated the contribution of smoking ban-unrelated factors to the reduced incidence of AMI incidence ob...
