Finding a needle in a haystack: toward a psychologically informed method for aviation security screening.

Finding a Needle in a Haystack

Current aviation security systems identify behavioral indicators of deception to assess risks to flights, but they lack a strong psychological basis or empirical validation. We present a new method that tests the veracity of passenger accounts. In an in vivo double-blind randomized-control trial conducted in international airports, security agents detected 66% of deceptive passengers using the ...

Phage display: selecting straws instead of a needle from a haystack.

An increasing number of peptides with specific binding affinity to various protein and even non-protein targets are being discovered from phage display libraries. The power of this method lies in its ability to efficiently and rapidly identify ligands with a desired target property from a large population of phage clones displaying diverse surface peptides. However, the search for the needle in...

Visual analysis for a sense-and-respond enterprise

A Sense-and-Respond enterprise is one that is constantly evolving to keep up with the rapidly a changing business environment. While these enterprises are "data rich," they are often at the same time "information poor." There is a critical need to: • Display large amounts of data – to see the both the "needle" and the "hay." • Make complex patterns stand out – to focus on relationships that are...

Presenting a New Method Based on Branch Placement for Optimal Placement of Phasor Measurement Units

In this paper, a new method based on branch placement for the optimal positioning of Phasor Measurement Units (PMUs) in power systems is proposed. In this method, the PMUs are in type of single-channel and are installed at the beginning of the branches. Therefore, they are able to measure the bus voltages. Also, the installation of the PMUs on the branches increases the security of observabilit...
