The proposed upgrades to both the LIGO and Virgo gravitational wave observatories will seek to improve detector sensitivity by reducing thermal noise. Based on technologies first implemented at the GEO600 detector, the test mass mirrors will be suspended using fused silica fibres of either circular or rectangular cross section to form monolithic suspensions. In GEO600 cylindrical fused silica f...

The interpretation of the optical Appell transformation, as previously elaborated in relation to the free-space paraxial propagation under both a rectangular and a circular cylindrical symmetry, is reviewed. Then, the caloric Appell transformation, well known in the theory of heat equation, is shown to be amenable for a similar interpretation involving the Laplace transform rather than the Four...

The application of ionizing radiations in different fields requires the use of equipment capable of detecting their presence or quantifying them. Detectors of the most different shapes, composition and characteristics are required to cover the full range of application of ionizing radiations. At present, thermoluminescent detectors (TLD) are the most widely employed for individual gamma monitor...

We measured the nondipole parameters for the spin-orbit doublets Xe 4d5/2 and Xe 4d3/2 over a photon-energy range from 100 eV to 250 eV at beamline 8.0.1.3 of the Advanced Light Source at the Lawrence Berkeley National Laboratory. Significant nondipole effects are found at relatively low energies as a result of Cooper minima in dipole channels and interchannel coupling in quadrupole channels. M...

OBJECTIVE This paper examined neurophysiological correlates of speech in children with language impairment (LI) and typical language development (TLD) across four experiments using different speech stimuli and tasks. METHODS The T-complex event-related potential (ERP) components and other ERP components (e.g., mismatch negativity [MMN]; N400) were examined. A subset of the children participat...

Given a graph G that admits a perfect matching, we investigate the parameter η(G) (originally motivated by computer graphics applications) which is defined as follows. Among all nonnegative edge weight assignments, η(G) is the minimum ratio between (i) the maximum weight of a perfect matching and (ii) the maximum weight of a general matching. In this paper, we determine the exact value of η for...
