Response to the U.S. Securities and Exchange’s Proposed Rule: Roadmap for the Potential Use of Financial Statements Prepared in Accordance with International Financial Reporting Standards by U.S. Issuers

Abstract: This paper is a response to the U.S. Securities and Exchange Commission’s request for comments on its proposed rule concerning a “Roadmap” for the use of financial statements prepared in accordance with International Financial Reporting Standards (IFRS) by U.S. issuers. The paper addresses only a few of the 70 multipart questions contained in the Roadmap. We find that while there are widely divergent opinions, little empirical evidence directly bears on the question of whether U.S. issuers should be required or permitted to adopt IFRS. We conclude that further analysis of the costs and benefits of a mandated transition to IFRS should be done. Notwithstanding the need for further analysis, we question whether it is justified to withhold from U.S. issuers the option to use IFRS for financial reports based on industry membership or size, when all non-U.S. issuers have the option to do so. While IFRS might marginally increase the concentration among audit firms, research suggests that concentration of audit services may be driven primarily by the litigious environment in the U.S. This suggests that concentration would be relatively unaffected by a change in accounting standards.

Performance of differential modulation with wireless relays in Rayleigh fading channels

Abstract: We propose a new amplify-and-forward scheme amenable to differential modulation for cooperative systems with wireless relays. We derive closed-form expressions of the probability density function (PDF) of the signal-to-noise ratio (SNR) and average bit-error rate (BER) for the proposed scheme and the analytical results are confirmed with numerical simulations. An asymptotic analysis reveals that the proposed cooperative scheme with one relay offers a diversity order approaching two in Rayleigh fading channels as the average SNR increases.

Ab initio relativistic effective potentials with spin-orbit operators. VII. Am through element 118

Abstract: Ab initio averaged relativistic effective core potentials (AREP) and spin-orbit (SO) operators are reported for the elements Am through element 118. Two sets have been calculated for certain elements to provide AREPs with varying core/valence space definition, thereby permitting the treatment of core/valence correlation interactions. The AREPs and SO operators are tabulated as expansions in Gaussian-type functions (GTF). GTF valence basis sets are derived for the lowest energy state of each atom. The reliability of the AREPs and SO operators is gauged by comparing calculated atomic orbital eigenvalues and SO splitting energies with all-electron relativistic values.

Fabrication and mechanical property of nano piezoelectric fibres

Abstract: Aligned piezoelectric (PZT) nanofibres were fabricated by electrospinning using PZT sol?gel as precursor. A pure perovskite phase with an average grain size of 10?nm was obtained at 650??C. The average diameter of these fibres could be controlled to range from 52 to 150?nm by varying the concentration of poly(vinyl pyrrolidone) (PVP) in the precursor. Special samples of PZT nanofibres were deposited across the microfabricated trenches on a silicon wafer. Atomic force microscopy (AFM) was used to measure the mechanical properties of a single nanofibre. The elastic modulus of an individual PZT nanofibre that was obtained was 42.99?GPa, which was smaller than that of a thin-film PZT. The possible reasons for the reduction in elastic modulus of the nanofibres were discussed.
