type="main" xml:id="jtsa12070-abs-0001"A two-step estimation method is proposed for periodic autoregressive parameters via residuals when the observations contain trend and periodic autoregressive time series. The oracle efficiency of the proposed Yule–Walker-type estimator is established. The...

A class of local correlation functions is obtained from B-spline bases and the corresponding stationary processes are constructed through local integration. Then a local Bayes estimate (LBE) is proposed using this process as a prior in a signal estimation problem. Mean square convergence of this...

High-pressure deuterium solid state NMR techniques have been used to study pyridine-d5 intercalated CdPS3. The effect of host compression on the dynamics of the intercalated molecule was observed. Deuterium powder pattern lineshapes were collected at four isotherms (270 K, 300 K, 330 K, 360 K)...

Energy intensity has gone through different stages across Chinese regions. In this paper, we investigate the stochastic electricity-intensity convergence across the Chinese provinces. Unlike previous work, this paper highlights the relevance of the level of technology of each province and takes...

In this paper, the authors propose an algorithm that increases and decreases the transmission speed according to a user-specified function. The design objective is to regulate baud as efficiently as possible and ensure that in each transmission interval, transmitter and receiver bauds are equal...
