      Univariate and multivariate feature selection methods can be used for biomarker discovery in analysis of toxicant exposure. Among the univariate methods, differential expression analysis (DEA) is often applied for its ...
    • Comparison of Discrete and Continuous Models for the Pooling Problem 

      Alfaki, Mohammed; Haugland, Dag (Chapter; Peer reviewed, 2011)
      The pooling problem is an important global optimization problem which is encountered in many industrial settings. It is traditionally modeled as a bilinear, nonconvex optimization problem, and solved by branch-and-bound ...
    • Computational Science in the 17th Century. Numerical Solution of Algebraic Equations: Digit–by–Digit Computation 

      Steihaug, Trond (Chapter, 2022)
      In this paper we give a complete overview of test–problems by Viète from 1600, Harriot from 1631 and Oughtred from 1647. The original material is not easily accessible due to archaic language and lack of conciseness. Viéte’s ...
    • A Continuous Max-Flow Approach to Minimal Partitions with Label Cost Prior 

      Yuan, Jing; Bae, Egil; Boykov, Yuri; Tai, Xue-Cheng (Chapter; Peer reviewed, 2011)
      This paper investigates a convex relaxation approach for minimum description length (MDL) based image partitioning or labeling, which proposes an energy functional regularized by the spatial smoothness prior joint with a ...
    • Convective chimneys and plumes in the Northern Greenland Sea 

      Johannessen, Ola M.; Lygre, Kjetil; Eldevik, Tor (Geophysical Monograph Series;30, Chapter, 2005)
      In the Boreas Basin in the northern Greenland Sea, convection has been observed to be localized as narrow structures - chimneys - in which the water masses may be homogeneous from the surface through great depths. An ...
    • Coring of unconsolidated permafrost deposits: methodological successes and challenges 

      Gilbert, Graham Lewis; Christiansen, Hanne H; Neumann, Ulrich (Chapter; Peer reviewed, 2015)

    • Cyclic homology in a special world 

      Dundas, Bjørn Ian (Chapter, 2020)
      In work of Connes and Consani, Γ-spaces have taken a new importance. Segal introduced Γ-spaces in order to study stable homotopy theory, but the new perspective makes it apparent that also information about the unstable ...
