Testing for unit roots based on sample autocovariances [PDF]
Biometrika, 2021 SummaryWe propose a new unit-root test for a stationary null hypothesis $H_0$ against a unit-root alternative $H_1$. Our approach is nonparametric as $H_0$ assumes only that the process concerned is $I(0)$, without specifying any parametric forms.

Improvement of an existing method of asynchronous sampling for determining RMS value [PDF]
Serbian Journal of Electrical Engineering, 2018 Measuring a value by definition seems to be the best solution for getting the most precise results. In this paper, it is shown that by changing the general definition of root mean square (RMS) and average value of a periodic signal, their ...

Root sampling and RNA extraction methods for field-based gene expression analysis of soybeans
Plant Production Science, 2021 Isolation of an adequate quantity of high-quality RNA is a crucial step in gene expression analysis. Difficulties in sampling and RNA extraction of field-grown crops, especially from roots, are substantial obstacles to understanding actual gene ...

Noisy low-rank matrix completion with general sampling distribution [PDF]
, 2014 In the present paper, we consider the problem of matrix completion with noise. Unlike previous works, we consider quite general sampling distribution and we do not need to know or to estimate the variance of the noise.

Phaseless Sampling on Square-Root Lattices
Foundations of Computational MathematicsAbstract Due to its appearance in a remarkably wide field of applications, such as audio processing and coherent diffraction imaging, the short-time Fourier transform (STFT) phase retrieval problem has seen a great deal of attention in recent years. A central problem in STFT phase retrieval concerns the question for which window functions
