Rare K+ Decays from Experiment E787 (open access)

Rare K+ Decays from Experiment E787

This paper presents the latest results from experiment E787, at Brookhaven National Laboratory, on K{sup +} {r_arrow} {pi}{sup +} {nu}{bar {nu}} and radiative K{sup +} decays. The result for K{sup +} {r_arrow} {pi}{sup +} {nu}{bar {nu}} uses data collected in runs taken during 1995, 1996 and 1997. In addition, they discuss plans for future measurements of K{sup +} {r_arrow} {pi}{sup +} {nu}{bar {nu}}.

National Needs Drivers for Nanotechnology (open access)

National Needs Drivers for Nanotechnology

Societal needs related to demographics, resources, and human behavior will drive technological advances over the next 20 years. Nanotechnology is anticipated to be an important enabler of these advances, and thus maybe anticipated to have significant influence on new systems approaches to solving societal problems as well as on extending current science and technology-based applications. To examine the potential implications of nanotechnology a societal needs-driven approach is taken. Thus the methodology is to present the definition of the problem, and then examine system concepts, technology issues, and promising future directions. We approach the problem definition from a national and global security perspective and identify three key areas involving the condition of the planet, the human condition, and global security. In anticipating societal issues in the context of revolutionary technologies, such as maybe enabled by nanoscience, the importance of working on the entire life cycle of any technological solution is stressed.

Digitally Marking RSA Moduli (open access)

Digitally Marking RSA Moduli

The moduli used in RSA (see [5]) can be generated by many different sources. The generator of that modulus (assuming a single entity generates the modulus) knows its factorization. They would have the ability to forge signatures or break any system based on this moduli. If a moduli and the RSA parameters associated with it were generated by a reputable source, the system would have higher value than if the parameters were generated by an unknown entity. So for tracking, security, confidence and financial reasons it would be beneficial to know who the generator of the RSA modulus was. This is where digital marking comes in. An RSA modulus ia digitally marked, or digitally trade marked, if the generator and other identifying features of the modulus (such as its intended user, the version number, etc.) can be identified and possibly verified by the modulus itself. The basic concept of digitally marking an RSA modulus would be to fix the upper bits of the modulus to this tag. Thus anyone who sees the public modulus can tell who generated the modulus and who the generator believes the intended user/owner of the modulus is.

Multiparticle Production at Rhic and Lhc: A Classical Point of View. (open access)

Multiparticle Production at Rhic and Lhc: A Classical Point of View.

We report results of our ongoing nonperturbative numerical study of a classical effective theory describing low-x partons in the central region of a heavy-ion collision. In particular, we give estimates of the initial transverse energies and multiplicities for a wide range of collision regimes, including those at RHIC and at LHC.

Experimental Testbed for the Study of Hydrodynamic Issues in Supernovae (open access)

Experimental Testbed for the Study of Hydrodynamic Issues in Supernovae

More than a decade after the explosion of SN 1987A, unresolved discrepancies still remain in attempts to numerically simulate the mixing processes initiated by the passage of a very strong shock through the layered structure of the progenitor star. Numerically computed velocities of the radioactive {sup 56}Ni and {sup 56}CO, produced by shock-induced explosive burning within the silicon layer for example, are still more than 50% too low as compared with the measured velocities. In order to resolve such discrepancies between observation and simulation, an experimental testbed has been designed on the Omega Laser for the study of hydrodynamic issues of importance to supernovae (SNe). In this paper, we present results from a series of scaled laboratory experiments designed to isolate and explore several issues in the hydrodynamics of SN explosions. The results of the experiments are compared with numerical simulations and are generally found to be in reasonable agreement.
