The Cryogenic Dark Matter Search experiment (CDMS) employs low-temperature Ge and Si detectors to detect WIMPs via their elastic scattering interaction with the target nuclei. The current analysis of 397.8 kg-days Ge exposure resulted in zero observed candidate events, setting an upper limit on the spin-independent WIMP-nucleon cross-section of 6.6× 10 cm (4.6× 10 cm, when previous CDMS Soudan ...

The ground state of Sn/Si(111) and Sn/Ge(111) surface alpha phases is reexamined theoretically, based on ab initio calculations where correlations are approximately included through the orbital dependence of the Coulomb interaction (in the local density+Hubbard U approximation). The effect of correlations is to destabilize the vertical buckling in Sn/Ge(111) and to make the surface magnetic, wi...

This paper describes a study concerning the interaction of oxygen with clean Ge(O01)2 x 1 surfaces in ultrahigh vacuum at 300 K. Surface conductance measurements, differential ellipsometry in the photon energy range of 1.5-4 eV and Auger electron spectroscopy have been used to monitor this solid-gas reaction. We observed in the joint density of states. as derived from ellipsometry. a peak at ab...

In Ge et al. (2001) the authors consider an interesting question. They assemble gene expression data from a yeast cell-cycle experiment (Cho et al., 1998), literature proteinprotein interaction (PPI) data and yeast two-hybrid data. We have curated the data slightly to make it simpler to carry out the analyses reported in Ge et al. (2001). In particular we reduced the data to the 2885 genes that...

Reaction of the PEt3 adduct of a disilylated five-membered cyclic germylene with group 4 metallocene dichlorides in the presence of magnesium led to the formation of the respective germylene metallocene phosphine complexes of titanium, zirconium, and hafnium. Attempts to react the related NHC adduct of a disilylated four-membered cyclic germylene under the same conditions with Cp2TiCl2 did not ...

The purpose was to examine adapted physical education (APE) specialists' perceptions about consultation as a delivery model for individuals with disabilities. Six APE specialists (4 female, 2 male) from California participated in this phenomenological study. Data came from in-depth individual interviews, field observations, researcher notes, and focus group interactions. Analysis revealed disti...

The utilization of polarized targets in scattering experiments has become a common practice in many major accelerator laboratories. Noble gases are especially suitable for such applications, since they can be easily hyper-polarized using spin exchange or metastable pumping techniques. Polarized helium-3 is a very popular target because it often serves as an effective polarized neutron due to it...

Conventional Polaroid time-of-flight (TOF) sonars provide object range measurements, but their wide beam widths limit the object bearing accuracy. We describe a first-order model that predicts the TOF readings from an object at given range, bearing, and reflecting strength produced by the Polaroid 6500 series sonar ranging module connected to a 600 series electrostatic transducer. The model pro...

We study binding corrections to the gyromagnetic factor ge of an electron in hydrogen-like ions. We argue that the leading order binding effects in radiative corrections ∆grad are universal to all orders in α/π and the complete result reads ∆grad = (gfree − 2) · [1 + (Zα) 2/6] + O ( α π · (Zα)4 ) . The theoretical uncertainty in the prediction for the experimentally interesting carbon ion is de...

Weak ferromagnetism of quasi-one-dimensional S = 1/2 antiferromagnet BaCu 2 Ge 2 O 7 is studied by the magnetization measurement. The spontaneous magnetization appears along the b axis below 8.8 K. The local symmetry between the intra-chain nearest neighbor spins allows the presence of Dzyaloshinskii-Moriya interaction, and the only possible spatial configuration of the weak ferromagnetic momen...
