bis(2-r-ind)zrcl2 (r: h or phenyl) was supported on different types of silica by in situ impregnation method and used for ethylene polymerization. in this method, the step of catalyst loading on support was eliminated and common alkyl aluminum (triisobutylaluminum, tiba) cocatalyst was used instead of expensive methyl aluminiumoxane (mao) cocatalyst in the polymerization. the effect of surface ...
Data from high-energy physics (HEP) experiments are collected with significant financial and human effort and are mostly unique. An inter-experimental study group on HEP data preservation and long-term analysis was convened as a panel of the International Committee for Future Accelerators (ICFA). The group was formed by large collider-based experiments and investigated the technical and organis...
To understand in detail duality between heterotic string and F theory compactifications, it is important to understand the construction of holomorphic G bundles over elliptic Calabi-Yau manifolds, for various groups G. In this paper, we develop techniques to describe these bundles, and make several detailed comparisons between the heterotic string and F theory.
We show that inflation can occur in the core of a Q-ball.
Extending the Minimal Supersymmetric Standard Model with three righthanded neutrino superfields is one of the best motivated scenarios for physics beyond the Standard Model. However, very little is known from observations about the high energy parameters of this model. In this paper we show, under the plausible assumptions that the neutrino Yukawa eigenvalues are hierarchical and the absence of...
Nuisance parameters are common in high energy physics (HEP), and various methods are used for incorporating their effects into measurements of physics interest. A survey of some of the professional statistics literature provides justification for and insight into most of the methods commonly used in HEP. There are extensions and refinements whose usefulness could still be explored, especially i...
We present our vision for Altocumulus, a new model for heterogeneous computing that establishes an intermediate layer between cloud computing and the devices at the edge of the network by harvesting their resources and coordinating their use. We discuss this idea by illustrating examples of potential applications and summarizing the results of our prior work that provide some base frameworks fo...
This white paper is sent by INFN network team, the Italian National Institute for nuclear physics, whose network, named INFNet, is a nationwide network founded to provide the access to existing national and international HEP laboratory and to facilitate communications between the researchers. With this paper we would like to emphasize the key points that we would to consider if charged with IPn...
This paper introduces an framework for adaptivity for a class of heterogeneous multiscale finite element methods for elliptic problems, which is suitable for a posteriori error estimation with separated quantification of the model error as well as the macroscopic and microscopic discretization errors. The method is derived within a general framework for “goal-oriented” adaptivity, the so-called...
In this paper we address a class of heterogeneous multi-vehicle task assignment and routing problem. We propose two distributed algorithms based on gossip communication: the first algorithm is based on a local exact optimization and the second is based on a local approximate greedy heuristic. We consider the case where a set of heterogeneous tasks arbitrarily distributed in a plane has to be se...
