A review of the hadron electromagnetic form factors obtained in a light-front constituent quark model, based on the eigenfunctions of a mass operator, is presented. The relevance of different components in the q-q interaction for the description of hadron experimental form factors is analysed.

Besides the fundamental challenge of creating a good problem, educators are faced with the task of deciding how to evaluate the technique’s effectiveness and how to assess whether...

The need for biologically based, quantitative risk assessment procedures for noncancer endpoints such as neurotoxicity has been discussed in reports by the United States Congress (Office of Technology Assessment, OTA), National Research Council (NRC), and a federal coordinating council. According to OTA, current attention and resources allocated to health risk assessment research are inadequate...

Industrial Control Systems (ICS) which control our critical infrastructures, including capabilities like bulk power generation, are unusually vulnerable to cyber attacks. The National Research Council (NRC) has reported that such an attack on the bulk power system “could deny large regions of the country access to bulk system power for weeks or even months. An event of this magnitude and durati...
