Building a Federated Catalog for CyberTraining Materials: The HPC-ED Pilot Project
To improve the sharing and discovery of CyberTraining materials, the HPC-ED Pilot project team is building a platform for the community to better share and find training materials through a federated catalog. The platform, currently in early test mode, is focused on a flexible platform, informative metadata, and community participation. By creating a framework for identifying, sharing, and including content broadly, HPC-ED will: allow providers of training materials to reach new groups of learners; extend the breadth and depth of training materials; and enable local sites to add or extend local portals
Topological Metal MoP Nanowire for Interconnect
The increasing resistance of Cu interconnects for decreasing dimensions is a
major challenge in continued downscaling of integrated circuits beyond the 7-nm
technology node as it leads to unacceptable signal delays and power consumption
in computing. The resistivity of Cu increases due to electron scattering at
surfaces and grain boundaries of the interconnects at the nanoscale.
Topological semimetals, owing to their topologically protected surface states
and suppressed electron backscattering, are promising material candidates to
potentially replace current Cu interconnects as low-resistance interconnects.
Here, we report the attractive resistivity scaling of topological metal MoP
nanowires and show that the resistivity values are comparable to those of Cu
interconnects below 500 nm cross-section areas. More importantly, we
demonstrate that the dimensional scaling of MoP nanowires, in terms of line
resistance versus total cross-sectional area, is superior to those of effective
Cu and barrier-less Ru interconnects, suggesting MoP is an attractive solution
to the current scaling challenge of Cu interconnects.Comment: 4 figure
pi-pi scattering in a QCD based model field theory
A model field theory, in which the interaction between quarks is mediated by
dressed vector boson exchange, is used to analyse the pionic sector of QCD. It
is shown that this model, which incorporates dynamical chiral symmetry
breaking, asymptotic freedom and quark confinement, allows one to calculate
, , and the partial wave amplitudes in -
scattering and obtain good agreement with the experimental data, with the
latter being well described up to energies \mbox{ MeV}.Comment: 23 Pages, 4 figures in PostScript format, PHY-7512-TH-93, REVTEX

Mosaic Amplification of Multiple Receptor Tyrosine Kinase Genes in Glioblastoma
SummaryTumor heterogeneity has been implicated in tumor growth and progression as well as resistance to therapy. We present an example of genetic heterogeneity in human malignant brain tumors in which multiple closely related driver genes are amplified and activated simultaneously in adjacent intermingled cells. We have observed up to three different receptor tyrosine kinases (EGFR, MET, PDGFRA) amplified in single tumors in different cells in a mutually exclusive fashion. Each subpopulation was actively dividing, and the genetic changes resulted in protein production, and coexisting subpopulations shared common early genetic mutations indicating their derivation from a single precursor cell. The stable coexistence of different clones within the same tumor will have important clinical implications for tumor resistance to targeted therapies
