Wavelets unit root test vs DF test : A further investigation based on monte carlo experiments [PDF]
Test for unit root based in wavelets theory is recently defined (Genay and Fan, 2007). While the new test is supposed to be robust to the initial value, we bring out by contrast the significant effects of the initial value in the size and the power.

Five‐year evaluation of linear accelerator‐based SRS platform isocentricity
Journal of Applied Clinical Medical Physics, Volume 26, Issue 4, April 2025.Abstract Linear accelerator (LINAC)‐based stereotactic radiosurgery (SRS) has become a mainstay in the management of intracranial tumors. However, the high fractional doses and sharp gradients used in SRS place heavy demands on geometric accuracy.

Is there Really a Unit Root in the Inflation Rate? More Evidence from Panel Data Models [PDF]
Time series unit root evidence suggests that inflation is nonstationary. By contrast, when using more powerful panel unit root tests, Culver and Papell (1997) find that inflation is stationary.

Non-Sationarity in the Consumption-Income Ratio: Further Evidence from Panel and Assymetric Unit Root Tests [PDF]
In this paper we test the stationarity properties of the consumption-income ratio for a sample of 14 European Union countries over the period 1960-1999 utilizing recent advances in panel unit root and asymmetric unit root tests. We find that a failure to

Hypoxia‐guided treatment planning for lung cancer with dose painting by numbers
Journal of Applied Clinical Medical Physics, Volume 26, Issue 4, April 2025.Abstract Tumor hypoxia significantly impacts the efficacy of radiotherapy. Recent developments in the technique of dose painting by numbers (DPBN) promise to improve the tumor control probability (TCP) in conventional radiotherapy for hypoxic cancer.

Panel Data Unit Roots Tests: The Role of Serial Correlation and the Time Dimension [PDF]
We investigate the influence of residual serial correlation and of the time dimension on statistical inference for a unit root in dynamic longitudinal data, known as panel data in econometrics.
