To imitate or differentiate: Cross-level identity work in an innovation network
Survival in global high-tech industries requires many organizations to participate in specialized innovation networks. However, sustained participation in these networks often proves more challenging than expected for organizations and their representatives, due to complex cross-level identity tensions that are indiscernible when only one level of analysis is considered. The purpose of this study is to analyze cross-level identity tensions at the interface of personal and organizational identities in an innovation network. We identify three key cross-level identity tensions related to intellectual property, communication and market definition, which together contribute to an overall organizational-personal identity tension opposing differentiation and imitation. These tensions are indicative of a complex process of “partial isomorphism” in identity work, which can facilitate collaboration while simultaneously fostering innovation among personal and organizational network members
Search for the Standard Model Higgs Boson in the Two-Electron and Two-Muon Final State with CMS
The decay of the Standard Model Higgs boson to ZZ(*), with both Zs decaying to leptons is one of the most important potential discovery channels for the Higgs boson at the LHC. The four lepton state with the highest branching ratio is the two-electron two-muon final state. This note presents the discovery potential of the Higgs boson using this channel at CMS for Higgs boson masses between 115 and 600 GeV. It is found that a Higgs boson with mass in the range 130 to 500 GeV, excluding a narrow region close to 170 GeV is expected to be observable at CMS with a significance exceeding 5 sigma with 30 fb^-1 of integrated luminosity
A sequential regularization method for time-dependent incompressible Navier--Stokes equations
The objective of the paper is to present a method, called sequential regularization method (SRM), for the nonstationary incompressible Navier-Stokes equations from the viewpoint of regularization of differential-algebraic equations (DAEs) , and to provide a way to apply a DAE method to partial differential-algebraic equations (PDAEs). The SRM is a functional iterative procedure. It is proved that its convergence rate is O(ffl m ), where m is the number of the SRM iterations and ffl is the regularization parameter. The discretization and implementation issues of the method are considered. In particular, a simple explicit difference scheme is analyzed and its stability is proved under the usual step size condition of explicit schemes. It appears that the SRM formulation is new in the Navier-Stokes context. Unlike other regularizations or pseudo-compressibility methods in the Navier-Stokes context, the regularization parameter ffl in the SRM need not be very small, and the regularized..
Thermo-mechanical sensitivity calibration of nanotorsional magnetometers
We report on the fabrication of sensitive nanotorsional resonators, which can
be utilized as magnetometers for investigating the magnetization dynamics in
small magnetic elements. The thermo-mechanical noise is calibrated with the
resonator displacement in order to determine the ultimate mechanical torque
sensitivity of the magnetometer.Comment: 56th Annual Conference on Magnetism and Magnetic Material
De Haas-van Alphen oscillations in the compensated organic metal alpha-'pseudo-kappa'-(ET)4H3O[Fe(C2O4)3].(C6H4Br2)
Field-, temperature- and angle-dependent Fourier amplitude of de Haas-van
Alphen (dHvA) oscillations are calculated for compensated two-dimensional (2D)
metals with textbook Fermi surface (FS) composed of one hole and two electron
orbits connected by magnetic breakdown. It is demonstrated that, taking into
account the opposite sign of electron and hole orbits, a given Fourier
component involves combination of several orbits, the contribution of which
must be included in the calculations. Such FS is observed in the strongly 2D
organic metal alpha-'pseudo-kappa'-(ET)4H3O[Fe(C2O4)3].(C6H4Br2), dHvA
oscillations of which have been studied up to 55 T for various directions of
the magnetic field with respect to the conducting plane. Calculations are in
good quantitative agreement with the data.Comment: European Physical Journal B (2014
Onsager phase factor of quantum oscillations in the organic metal theta-(BEDT-TTF)4CoBr4(C6H4Cl2)
De Haas-van Alphen oscillations are studied for Fermi surfaces illustrating
the Pippard's model, commonly observed in multiband organic metals. Field- and
temperature-dependent amplitude of the various Fourier components, linked to
frequency combinations arising from magnetic breakdown between different bands,
are considered. Emphasis is put on the Onsager phase factor of these
components. It is demonstrated that, in addition to the usual Maslov index,
field-dependent phase factors must be considered to precisely account for the
data at high magnetic field. We present compelling evidence of the existence of
such contributions for the organic metal theta-(BEDT-TTF)4CoBr4(C6H4Cl2)
