This paper provides a critical assessment of the austerity measures that are being implemented in the crisis-stricken countries of the Eurozone, and in particular, the implications of internal devaluation for the Greek economy. The theoretical underpinnings and phases of internal devaluation are explored. A detailed statistical analysis of key macroeconomic indicators pertaining to the Greek economy is carried out. Alternatives to internal devaluation are proposed in this paper, laying the foundations for a reassessment of the policy of austerity and the implications for recovery and sustainability of economic activity in Greece and other countries of the Eurozone.

Background Limited evidence exists to support very early intensive aphasia rehabilitation after stroke. VERSE is a PROBE trial designed to determine whether two types of intensive aphasia therapy, beginning within 14 days of acute stroke, provide greater therapeutic and cost-effectiveness than usual care. Objective To publish the detailed statistical analysis plan for the VERSE trial prior to unblinding. This statistical analysis plan was based on the published and registered VERSE trial protocol and was developed by the blinded steering committee and management team, led by the trial statistician. This plan was developed using outcome measures and trial data collection forms. Results The VERSE statistical analysis plan is consistent with reporting standards for clinical trials and provides for clear and open reporting. Conclusions Publication of a statistical analysis plan serves to reduce potential trial reporting bias and outlines transparent pre-specified analyses. Australian New Zealand Clinical Trials Registry (ANZCTR) Registration number: ACTRN12613000776707; Universal Trial Number (UTN) is U1111-1145-4130.

This article presents the first detailed statistical analysis of the volatilities of various commonly encountered financial metrics used in contingent consideration (and earn-out) agreements. The valuation of contingent consideration using an option-based methodology and non-equity volatilities is becoming more common in business valuation. We provide clear evidence that the volatility of five financial metrics—revenue; earnings before interest, taxes, depreciation, and amortization (EBITDA); EBIT, net income, and total assets—is strongly, negatively related to firm size and profitability. However, contrary to common belief, the volatility of these metrics is not related to a firm's financial leverage. We also calculated the volatilities using four different methodologies that are employed in practice. Although no theory guides the selection of methodologies, based upon our work, we have found that the year-over-year growth rate, using a quarterly frequency, provides the most reasonable results.

For a stream cipher to be secure, the keystream generated by it should be uniformly random with parameter 1/2.Statistical tests check whether the given sequence follow a certain probability distribution. In this paper, we perform a detailed statistical analysis of various stream ciphers used in GSM 2G,3G, 4G and 5G communications. The sequences output by these ciphers are checked for randomness using the statistical tests defined by the NIST Test Suite. It should also be not possible to derive any information about secret key and the initial state ofthe cipher from the keystream. Therefore, additional statisticaltests based on properties like Correlation between Keystreamand Key, and Correlation between Keystream and IV are also performed. Performance analysis of the ciphers also has been done and the results tabulated. Almost all the ciphers pass thetests in the NIST test suite with 99% confidence level. For A5/3stream cipher, the correlation between the keystream and key is high and correlation between the keystream and IV is low when compared to other ciphers in the A5 family.

The association between plasma cholesterol levels and the development of dementia continues to be an important topic of discussion in the scientific community, while the results in the literature vary significantly. We study the effect of reducing oxidized neuronal cholesterol on the lipid raft structure of plasma membrane. The levels of plasma membrane cholesterol were reduced by treating the intact cells with methyl-ß-cyclodextrin (MßCD). The relationship between the cell viability with varying levels of MßCD was then examined. The viability curves are well described by a modified form of the empirical Gompertz law of mortality. A detailed statistical analysis is performed on the fitting results, showing that increasing MßCD concentration has a minor, rather than significant, effect on the cellular viability. In particular, the dependence of viability on MßCD concentration was found to be characterized by a ~25% increase per 1 μM of MßCD concentration.

The paper is focused on the determination of the course and change of the surface quality parameters obtained by the laser engraving of the material known under commercial name polymethyl methacrylate. The paper aims to find mathematical relations based on regression analysis for amplitudes parameters Ra and Rz. For this purpose, a sample of variable technology parameters will be machined followed by the surface measuring and evaluation using the Talysurf CLI 500 3D Surface Scanner. Thus the data obtained will be subjected to the detailed statistical analysis to check homoscedasticity, the presence of outliers, and multidimensional normality testing.
