Population Structure, Genetic Diversity and Molecular Marker-Trait Association Analysis for High Temperature Stress Tolerance in Rice. [PDF]

open access: yesPLoS ONE, 2016
Rice exhibits enormous genetic diversity, population structure and molecular marker-traits associated with abiotic stress tolerance to high temperature stress. A set of breeding lines and landraces representing 240 germplasm lines were studied.

Allometric Individual Leaf Area Estimation in Chrysanthemum

open access: yesAgronomy, 2021
A model for estimating the area of individual leaves (LA) by employing their dimensions was developed for chrysanthemum. Further hypotheses were tested: (a) LA estimation is improved by considering blade length (Lb) rather than leaf length (L), and (b) a

New in situ aerosol hyperspectral optical measurements over 300–700 nm – Part 1: Spectral Aerosol Extinction (SpEx) instrument field validation during the KORUS-OC cruise [PDF]

open access: yesAtmospheric Measurement Techniques, 2021
In situ observations of spectrally resolved aerosol extinction coefficients (300–700 nm at ∼ 0.8 nm resolution) from the May–June 2016 Korea–United States Ocean Color (KORUS-OC) oceanographic field campaign are reported.

Auxiliary Variable-Aided Hybrid Message Passing for Joint Channel, Phase Noise Estimation and Detection for Multi-User MIMO Systems

open access: yesIEEE Open Journal of the Communications Society, 2023
This paper considers a multi-user multiple-input multiple-output (MU-MIMO) system with independent phase noise (PN) at user terminals (UTs) due to non-synchronous noisy local oscillators.

An AMP-Based Low Complexity Generalized Sparse Bayesian Learning Algorithm

open access: yesIEEE Access, 2019
In this paper, an approximate message passing-based generalized sparse Bayesian learning (AMP-Gr-SBL) algorithm is proposed to reduce the computation complexity of the Gr-SBL algorithm, meanwhile improving the robustness of the GAMP algorithm against the

Cross Assessment of Twenty-One Different Methods for Missing Precipitation Data Estimation

open access: yesAtmosphere, 2020
The results of metrological, hydrological, and environmental data analyses are mainly dependent on the reliable estimation of missing data. In this study, 21 classical methods were evaluated to determine the best method for infilling the missing ...

I-V-T Characteristics and Temperature Sensor Performance of a Fully 2-D WSe2/MoS2 Heterojunction Diode at Cryogenic Temperatures

open access: yesIEEE Journal of the Electron Devices Society, 2023
In this work, we demonstrate the usability of a fully-2D-material based device consisting of MoS2/WSe2 heterojunction encapsulated by hBN and contacted by graphene as temperature sensor for linear temperature measurement at cryogenic temperatures.

Data inversion methods to determine sub-3 nm aerosol size distributions using the particle size magnifier [PDF]

open access: yesAtmospheric Measurement Techniques, 2018
Measuring particle size distribution accurately down to approximately 1 nm is needed for studying atmospheric new particle formation. The scanning particle size magnifier (PSM) using diethylene glycol as a working fluid has been used for ...

A statistical mechanical approach for the computation of the climatic response to general forcings [PDF]

open access: yesNonlinear Processes in Geophysics, 2011
The climate belongs to the class of non-equilibrium forced and dissipative systems, for which most results of quasi-equilibrium statistical mechanics, including the fluctuation-dissipation theorem, do not apply.
