    Fine-grained traffic flow measurement, which provides useful information for network management tasks and security analysis, can be challenging to obtain due to monitoring resource constraints. The alternate approach of inferring flow statistics from partial measurement data has to be robust against dynamic temporal/spatial fluctuations of network traffic. In this paper, we propose an intelligent Traffic Aggregation and Measurement Paradigm, which partitions TCAM entries of switches/routers into…Read more

    We present new results on the Hubble diagram of distant type Ia supernovae segregated according to the type of host galaxy. This makes it possible to check earlier evidence for a cosmological constant by explicitly comparing SNe residing in galaxies likely to contain negligible dust with the larger sample. The cosmological parameters derived from these SNe Ia hosted by presumed dust-free early-type galaxies support earlier claims for a cosmological constant, which we demonstrate at ≃5σ significa…Read more

    Measurement of Ω m, Ω Λ from a blind analysis of Type Ia supernovae with CMAGIC: Using color information to verify the acceleration of the universe
    with A. Conley, G. Goldhaber, G. Aldering, R. Amanullah, E. D. Commins, V. Fadeyev, G. Folatelli, G. Garavini, R. Gibbons, A. Goobar, I. de GroomHook, A. G. da HowellKim, R. A. Knop, M.

    We present measurements of Ωm and Ω Λ from a blind analysis of 21 high-redshift supemovae using a new technique for fitting the multicolor light curves of Type la supernovae, first introduced by Wang and coworkers. CMAGIC takes advantage of the remarkably simple behavior of Type la supernovae on color-magnitude diagrams and has several advantages over current techniques based on maximum magnitudes. Among these are a reduced sensitivity to host galaxy dust extinction, a shallower luminosity-width…Read more

    A shed NKG2D ligand that promotes natural killer cell activation and tumor rejection
    with W. Deng, B. G. Gowen, L. Zhang, S. Lau, A. Iannello, J. Xu, T. L. Rovis, N. Xiong, and D. H. Raulet
    Immune cells, including natural killer cells, recognize transformed cells and eliminate them in a process termed immunosurveillance. It is thought that tumor cells evade immunosurveillance by shedding membrane ligands that bind to the NKG2D-activating receptor on NK cells and/or Tcells, and desensitize these cells. In contrast, we show that in mice, a shed form of MULT1, a high-affinity NKG2D ligand, causes NK cell activation and tumor rejection. Recombinant soluble MULT1 stimulated tumor reject…Read more
  • Spectral models for early time SN 2011fe observations
    with E. Baron, P. Hoeflich, B. Friesen, M. Sullivan, E. Hsiao, R. S. Ellis, A. Gal-Yam, P. E. da HowellNugent, I. Dominguez, K. Krisciunas, M. M. Phillips, N. Suntzeff, and R. C. Thomas
    © 2015 The Authors. Published by Oxford University Press on behalf of the Royal Astronomical Society.We use observedUVthrough near-IR spectra to examine whether SN 2011fe can be understood in the framework of Branch-normal Type Ia supernovae and to examine its individual peculiarities. As a benchmark, we use a delayed-detonationmodel with a progenitormetallicity of Z⊙/20. We study the sensitivity of features to variations in progenitor metallicity, the outer density profile, and the distribution…Read more

    Recognition of tumors by the innate immune system and natural killer cells
    with Marcus A., B. G. Gowen, T. W. Thompson, A. Iannello, M. Ardolino, W. Deng, N. Shifrin, and D. H. Raulet
    In recent years, roles of the immune system in immune surveillance of cancer have been explored using a variety of approaches. The roles of the adaptive immune system have been a major emphasis, but increasing evidence supports a role for innate immune effector cells such as natural killer cells in tumor surveillance. Here, we discuss some of the evidence for roles in tumor surveillance of innate immune cells. In particular, we focus on NK cells and other immune cells that express germline-encod…Read more

    A selective role of NKG2D in inflammatory and autoimmune diseases
    with N. Guerra, K. Pestal, T. Juarez, J. Beck, K. Tkach, and D. H. Raulet
    The NKG2D activating receptor has been implicated in numerous autoimmune diseases. We tested the role of NKG2D in models of autoimmunity and inflammation using NKG2D knockout mice and antibody blockade experiments. The severity of experimental autoimmune encephalitis was decreased in NKG2D-deficient mice when the disease was induced with a limiting antigen dose, but unchanged with an optimal antigen dose. Surprisingly, however, NKG2D deficiency had no detectable effect in several other models, i…Read more

Genome-wide gene expression measurements have enabled comprehensive studies that integrate the changes of gene expression and phenotypic information to uncover their novel associations. Here we reported the association analysis between psychophysical phenotypes and genome-wide gene expression changes in human adaptation to one of the most extreme climates on Earth, the Antarctic Dome Argus. Dome A is the highest ice feature in Antarctica, …Read more
