the United States' cold war experience was reopened when Energy Secretary Hazel O'Leary responded to news media reports about government-sponsored radiation research involving hundreds of human subjects, often without their informed consent. At a December 7 press conference on her initiative to declassify some of the U.S. Department of Energy's (DOE) nuclear research records, O'Leary commented ...

; The Pade approximant problem is related to a (not necessarily orthogonal) projection of a linear functional equation of the Fredholni type. If the kernel is of trace class and its upper Hessenberg form is tridiagonal (this class includes Hermitian operators), then we prove that not only do the diagonal Pade' appioximants converge, but so do their numerators and denominators separately. The ge...

For an optimal functionality and a high durability of the planned SIS18 beam loss collimators a low ion-induced desorption yield of the collimator material is required. Gold coated copper was found to be the material of choice: copper has a high thermal conductivity, a high specific heat and can be produced with high purity for reasonable prizes. The gold layer prevents the copper from oxidatio...

A new criterion for driving a recursive partitioning decision rule for nonparametric classification is presented. The criterion is both conceptually and computationally simple, and can be shown to have strong statistical merit. The resulting decision rule is asymptotically Bayes risk efficient. The notion of adaptively generated features is introduced and methods are presented for dealing with ...

means, patience, management, and technical skills they are likely to have." First, neither plutonium nor uranium, the materials from which bombs are made, is "highly radioactive." They are alpha emitters and as long as they are not breathed in or absorbed through a cut they can be safely handled for hours without any significant radiological hazard. Is it really so difficult to make a crude bom...

Ion heating at the fundamental of the cyclotron resonance (1 M H z s 3 MHz) in a toroidal octupole magnetic field is found to be in good agreement with single particle, cold plasma theory at power levels PabrS 100 kW (E 5 100 Vlm) and ion temperatures kT, S 600 eV. Good penetration of the electric field is observed in the densest available plasmas (n7 x lo'* cmA3) with no evidence of parametric...

The high and middle intertidal zones of the northeastern portion ("barren") of the limestone bench on the windward side of Enewetak Island, Enewetak Atoll, Marshall Islands, have a significantly higher number of herbivorous fishes grazing at high tide than the same intertidal zones of the reef flat 300 m to the southwest ("algae-covered"). This portion of the reef flat in the barren, heavily gr...

Ag thin films with a nominal thickness of 80 nm were vacuum evaporated onto a Si substrate. The thin Ag2S layers were grown by depositing sulfur onto the Ag surfaces in a clean environment. First, analytic grade sulfur powder was loaded in a quartz tube, melted and cooled back in order to ensure a homogenous source. The thin film sample was then loaded in the tube to a distance of 2 cm from the...
