In studies of subjective well-being, economists and other researchers typically use a fixed or random effect estimation to control for unobservable heterogeneity across individuals. Such individual heterogeneity, although substantially reducing the estimated effect of many characteristics, is little understood. This paper shows that personality measures can account for 20% of this heterogeneity...

Superoxide generated adventitiously by the mitochondrial respiratory chain can give rise to much more reactive radicals, resulting in random oxidation of all classes of macromolecules. Harman's 1956 suggestion that this process might drive aging has been a leading strand of biogerontological thinking since the discovery of superoxide dismutase. However, it has become apparent that the many down...

In the case of the process e+e− → μ+μ−, we study the sensitivity to either Z ′ or anomalous gauge coupling effects of two new observables, σ+ and σ−, conveniently defined for such kind of analysis. We discuss general properties of the deviations of these observables from the Standard Model predictions, and derive the model-independent bounds on the relevant parameters allowed by present and for...

The number of qubits used by a quantum algorithm will be a crucial computational resource for the foreseeable future. We show how to obtain the classical query complexity for continuous problems. We then establish a simple formula for a lower bound on the qubit complexity in terms of the classical query complexity.

In reality, we need an emergency response plan for all foreseeable emergencies. One pattern of viewing emergency response plans is as a continuum, from the least complex emergency to the most complex. The sudden cardiac arrest (SCA) emergency is the least complex; followed by all medical emergencies; then non-medical emergencies, such as fire, bombs, active shooters; and finally the most comple...

General considerations of the requirements for a high energy linear collider (here, to be specific, taken to be 1 TeV on 1 TeV) are applied to free-space laser and laser/plasma accelerators. It is shown that the requirements impose very severe constraints upon the new accelerators-so severe, that it seems unlikely that these necessary criteria can be met in the foreseeable future.

While there has been much discussion about how people, tasks, and organizational and social context should shape the interactions in ubiquitous computing environments, little has been said about what effect technical constraints have. In this paper, we identify four essential technological challenges in ubicomp, that is ones that are unlikely to be overcome in the foreseeable future, and discus...
