Coronal Mass Ejections (CMEs) are large, energetic expulsions of mass and magnetic fields from the Sun; they can significantly affect large volumes of the heliosphere and appear to be a key cause of geomagnetic storms. The present study deals with the influence of Asymmetric 'Full' Halo CMEs, Partial Halo CMEs, Asymmetric and Complex 'Full' Halo CMEs and 'Full' Halo CMEs on cosmic ray intensity...

We study the effects of halo substructure and a distribution in the concentration parameter of haloes on large-scale structure statistics. The effects on the power spectrum and bispectrum are studied on the smallest scales accessible from future surveys. We compare halo-model predictions with results based on N -body simulations, but also extend our predictions to 10kpc scales which will be pro...

Recent high-profile corporate scandals are reminiscent of the corporate raider scandals of the 1980s, suggesting that ethical scandals may occur in waves. This article provides a framework for analysis of this question by suggesting that ethical attitudes may be cyclical about long-term secular trends. We provide some empirical evidence from previously published work for the existence of cycles...

The nature of the Massive Compact Halo objects seen in microlensing experiments and interpreted as dark matter in the Halo of our Galaxy remains a mystery. Arguments are presented that these events are probably not ordinary stellar or substellar objects, i.e., they are probably not faint stars, brown dwarfs, white dwarfs, or neutron stars. On theoretical grounds one is then pushed to either exo...

We present in detail a theoretical model for fragmentation reactions of three–body halo nuclei. The different reaction mechanisms corresponding to the different processes are described and discussed. Coulomb and nuclear interactions are simultaneously included and the method is therefore applicable for any target, light, intermediate and heavy. Absolute values of many differential cross section...

A sudden depletion or intensity “dimming” of the X-ray corona sometimes accompanies a solar eruptive flare or coronal mass ejection (CME). We have identified a dimming that occurred just prior to a “halo” CME, observed on 1997 April 7 using the Soft X-ray Telescope (SXT) on Yohkoh. Halo CMEs are prime candidates for “space weather” effects. The dimming occurred in compact regions near a flare o...

T he Computers, Software, and Applications Conference (COMPSAC), a Signature Conference of the IEEE Computer Society (CS), celebrated its 40th anniversary this year in Atlanta, Georgia, from June 10–14. This year also marks the 70th anniversary of the CS. As a signature CS conference, sponsored directly by the CS Board of Governors, COMPSAC’s mission is to serve the professional interests of al...
