The 1111-type iron-based superconductor LnFeAsO(1-x)Fx (Ln stands for lanthanide) is the first material with a Tc above 50 K, other than cuprate superconductors. Electron doping into LaFeAsO by H, rather than F, revealed a double-dome-shaped Tc-x diagram, with a first dome (SC1, 0.05<x<0.20) and a second dome (SC2, 0.2<x<0.5). Here, we report the Tc for the whole hydrogen-doping range in LaFeAs...

BACKGROUND Relapsing fever (RF) spirochetes are notable for multiphasic antigenic variation of polymorphic outer membrane lipoproteins, a phenomenon responsible for immune evasion. An additional role in tissue localization is suggested by the finding that isogenic serotypes 1 (Bt1) and 2 (Bt2) of the RF spirochete Borrelia turicatae, which differ only in the Vsp they express, exhibit marked dif...

In this article we extend the definition of wavelet variance to wavelet packets. We also adapt to wavelet packets an iterated cumulative sum of squares algorithm for the location of variance change points. Wavelet packets have greater decorrelation properties than standard wavelets in that they induce a finer partitioning of the frequency domain of the process generating the data. This allows o...

This paper presents the design and development of a carbon fiber reinforced plastic dome, including a description of the dome fabrication, method for sealing penetrations in the dome, and a summary of the planned test series. This dome will be used for the experimental permeability characterization and leakage validation of composite vessels pressurized using liquid hydrogen and liquid nitrogen...

The design of future large optical telescopes must take into account the wind-induced vibration of the telescope structure that is caused by large-scale flow structures and turbulence inside the telescope enclosure when the aperture in the enclosure dome is open. However, estimating the resulting degradation in image quality is difficult due to our relatively poor understanding of the flow insi...

Dome is an object based parallel programming environment for heterogeneous distributed networks of machines. This paper gives a brief overview of Dome. We show that Dome programs are easy to write. A description of the load balancing performed in Dome is presented along with performance measurements on a cluster of DEC Alpha workstations connected by a DEC Gigaswitch. A Dome program is compared...

Since the literature lacks an effective analysis method of collapse mechanisms and optimisation design theory for progressive resistance cable dome structure, a structural performance-based approach was proposed to improve structures in this study. First, dynamic response model structure were analysed after its members removed using Ansys LS-DYNA full equivalent load-based instantaneous unloadi...

A structural shape optimization problem, with respect to the structural aspect ratio is developed in the context of an axisymmetric structural-acoustic system, consisting of an elastic dome coupled with an internal acoustic cavity, is analyzed in the lowand medium-frequency ranges. The dome is a thin shell considered as a three-dimensional continuum with a dissipative constitutive equation. The...
