Atmospheric neutrinos produced by cosmic-ray interactions in the atmosphere are of interest for several reasons. As a beam for studies of neutrino oscillations they cover a range of parameter space hitherto unexplored by accelerator neutrino beams. The atmospheric neutrinos also constitute an important background and calibration beam for neutrino astronomy and for the search for proton decay an...

Methodical approaches used in the computational model “PROLOG” are given in the paper. This model is intended for assessing radiological situations and an efficiency of counter measures after short term radioactive releases. Basic local Gaussian dispersion algorithm is supplemented with modules for assessing a plume rise, dry deposition velocities, effect of buildings and complex terrain, etc. ...

Multidisciplinary research into statistical and soft computing models is detailed that analyses data on inmissions of atmospheric pollution in urban areas. The research analyzes the impact on atmospheric pollution of an extended bank holiday weekend in Spain. Levels of atmospheric pollution are classified in relation to the days of the week, seeking to differentiate between working days and non...

This paper focuses on the differences in earnings and labor force status of low-skilled prime age men in France, the United Kingdom, and the United States at the end of the 20th century, and their relation to the differences in wage dispersion. In the UK and the US, where the bottom of the wage distribution is more dispersed, the inactivity rate (sometimes called the not-in-labor force rate) am...

]Komogeneous wave guide theory is used to derive dispersion curves, vertical pressure distributions, and synthetic baregrams for atmospheric waves. A complicated mode structure is found involving both gravity and acoustic waves. Various models of the atmosphere are studied to explore seasonal and geographic effects on pulse propagation. The influence of different zones in the atmosphere on the ...

Recent Royal Aircraft Establishment research on gusts has been particularly concerned with severe gusts and the situations in which they occur. In the stratosphere, mountain wave conditions and the vicinity of thunderstorm tops have been investigated. A t lower altitudes, gusts in and near thunderstorms have also been studied, as have wind and gust effects likely t o be significant during takeo...

We analyze non-cooperative environmental policy when the only strategic interaction between countries is through bilateral transboundary pollution, i.e., countries are closed or small open economies. When countries set pollution taxes simultaneously, there is no carbon leakage. However, in the sequential-move game, the leader sets its pollution tax lower than the marginal damage from own pollut...

We have previously presented 5.7 σ evidence for a smaller α at redshifts 0.2 < zabs < 3.7 from a sample of 128 Keck/HIRES quasar absorption systems: α/α = (−0.57 ± 0.10) × 10−5. A non-zero α/α manifests itself as a distinct pattern of shifts in the measured absorption line wavelengths. The statistical error is now small: we do detect small line shifts in the HIRES data. Whether these shifts are...

Standard search and matching models of equilibrium unemployment, once properly calibrated, can generate only a small amount of frictional wage dispersion, i.e., wage differentials among ex-ante similar workers induced purely by search frictions. We derive this result for a specific measure of wage dispersion—the ratio between the average wage and the lowest (reservation) wage paid. We show that...
