We examine a recent claim that Debye screening will affect the charge transport mechanism of anomalous electroweak baryogenesis, and show that the effects of gauge charge screening do not affect the baryon number produced during a first order electroweak phase transition.

We argue that the linear static potential is built in into the common procedure of extracting it from lattice Wilson loop measurements. To illustrate the point, we extract the potential by the standard lattice method in a model vacuum made of instantons. A beautiful innnitely rising linear potential is obtained in the case where the true potential is actually attening. We argue that the ux tube...

An increased sensitivity of airport detectors, a growing number of isotopic tests, and globalization of the society have raised a number of false positive radioactive alarms at airports and public places. This paper presents two new cases of patients who triggered airport security alarms after receiving 740MBq of (131)I for non-toxic goitre and attempts to compare surprisingly limited literatur...

Do firms have adequate incentives to invest in anti-terrorism mechanisms? This paper develops a framework for addressing this issue when the security choices by one agent affect the risks faced by others. We utilize the airline security problem to illustrate how the incentive by one airline to invest in baggage checking is affected by the decisions made by others. Specifically if an airline bel...

The discoveries and open questions in neutrino physics, as reported at Neutrino 2002 and more recently, are reviewed from a theoretical perspective. During the last several years, stunning experimental results have established that neutrinos almost certainly have nonzero masses and mix. This development opens a whole new world for us to explore. What have we already learned about the neutrinos,...

Border control is vital to the security of a nation and its citizens. All countries look at measures to improve the security of their borders. But increasing security can bring a substantial financial burden. In this study, we analyze the border security problem of Turkey using a simulation approach. Our main objective is to find more efficient ways of improving border control and security alon...

This paper reports on the results of two studies involving the development and construct validation of a short form of the Career Orientations Inventory. The short form was factor analytically derived and tested in two separate field studies of IS employees. The short form measures nine career orientations: technical, managerial, autonomy, job security, geographic security, service, pure challe...

We propose a system to automatically measure the body temperature of persons as they pass. In contrast to exisitng systems, the persons do not need to stop and look into a camera one-by-one. Instead, their eye corners are automatically detected and the temperatures therein measured using a thermal camera. The system handles multiple simultaneous persons and can thus be used where a flow of peop...
