Nonparametric Detection of a Time‐Varying Mean

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT We propose a nonparametric portmanteau test for detecting changes in the unconditional mean of a univariate time series which may display either long or short memory. Our approach is designed to have power against, among other things, cases where the mean component of the series displays abrupt level shifts, deterministic trending behaviour ...

CitPH4 Confers Resistance to Citrus Canker by Activating Papain‐Like Cysteine Protease

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Citrus canker, a devastating disease caused by Xanthomonas citri subsp. citri (Xcc), poses a significant threat to global citrus production due to the high susceptibility of nearly all commercial citrus cultivars to it. Although transcription factor Citrus PH4 (CitPH4) is well known for regulating fruit acidity, its potential role in plant ...

New medicine for soil restoration: biological soil crust capsules facilitate native plant and soil microbe establishment

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Restoration in drylands is challenging because of harsh climates, requiring creative methods and organisms like biocrusts for restoration of degraded lands. Biocrusts are thin, coherent soil surface layers prevalent in drylands, engineered, and inhabited by communities of organisms including mosses, lichens, and cyanobacteria ...

Determination of efficiencies, loss mechanisms, and performance degradation factors in chopper controlled dc vehical motors. Section 2: The time dependent finite element modeling of the electromagnetic field in electrical machines: Methods and applications [PDF]

open access: yes
The time dependent solution of the magnetic field is introduced as a method for accounting for the variation, in time, of the machine parameters in predicting and analyzing the performance of the electrical machines.
