PURPOSE The severity of a stroke cannot be described by widely used prehospital stroke scales. We investigated the usefulness of the Kurashiki Prehospital Stroke Scale (KPSS) for assessing the severity of stroke, compared to the National Institutes of Health Stroke Scale (NIHSS), in candidate patients for intravenous or intra-arterial thrombolysis who arrived at the hospital within 6 hours of s...

We show that the power of the KPSS-test against integration, as measured by divergence rates of the test statistic under the alternative, remains the same when residuals from an OLS-regression rather than true observations are used. This is in stark contrast to residual based tests of the null of integration in a cointegration setting, where power is drastically reduced when residuals are used....

Mitochondria are morphologically dynamic organelles which undergo fission and fusion processes. Our previous study found that arterial constriction was always accompanied by increased mitochondrial fission in smooth muscle cells, whereas inhibition of mitochondrial fission in smooth muscle cells was associated with arterial relaxation. Here, we used the typical vasorelaxants, verapamil and phen...

The paper introduces order of integration test (OIT) which serves as a simple alternative to unit root built generally using auxiliary autoregressive AAR(3) model. parametric boundary conditions necessary and sufficient for testing the null hypothesis that non-stationary variable under is integrated zero I(0) were estimated via generalized least squares (GLS). decision on evaluated t-statistic....

The study at hand concentrates on existing stationarity tests as well as some of their variants and generalizations. It also focuses on the results of applying time series methods to univariate non-stationary data in order to stress the importance that stationarity plays in generating accurate and reliable estimates and forecast models to describe the data. Part A of the study focuses on variou...

Collusion susceptible key predistribution schemes (KPS) are trade-offs between complexity and security. Measures of complexity include storage, computation and bandwidth overhead; a measure of security is their collusion resistance. Probabilistic KPSs (P-KPS) have some unique advantages in application scenarios where hardware assisted protection of secrets is mandatory. To facilitate a quantita...

Marketing research has identified several benefits of dynamic pricing strategies in the retail industry. However, today’s retailers are limited to apply them in real-time to customer needs as corresponding pricing services provided by smart product infrastructures have not been adopted so far. In addition, dynamic pricing strategies rely on a business service ecosystem of retailers, suppliers, ...

We propose a formal method to test stationarity for spatial point processes. The proposed test statistic is based on the integrated squared deviations of observed counts of events from their means estimated under stationarity. We show that the resulting test statistic converges in distribution to a functional of a two-dimensional Brownian motion. To conduct the test, we compare the calculated s...

This paper proposes a new stationarity test based on the KPSS test with less size distortion. We extend the boundary rule proposed by Sul, Phillips and Choi (2005) to the autoregressive spectral density estimator and parametrically estimate the long-run variance. We also derive the finite sample bias of the numerator of the test statistic up to the 1/T order and propose a correction to the bias...
