Potassium transporter KUP9 participates in K+ distribution in roots and leaves under low K+ stress [PDF]

open access: yesStress Biology, 2022
Potassium (K) is a major essential element in plant cells, and KUP/HAK/KT-type K+ transporters participate in the absorption of K+ into roots and in the long-distance transport to above-ground parts.

A method for estimating the parameters of the K distribution

open access: yesIEEE Transactions on Signal Processing, 1999
A method that combines the maximum likelihood and the method of moments for estimating the parameters of the K distribution is proposed. The method results in the lowest variance of parameter estimates when compared with existing non-ML techniques.

Impact of Finite-Sized Aperture on the Performance of Differential Multihop DF-FSO Network [PDF]

open access: yesInternational Journal of Electronics and Telecommunications, 2022
This paper investigates the differential binary modulation for decode-and-forward (DF) based relay-assisted free space optical (FSO) network under the effect of strong atmospheric turbulence together with misalignment error (ME).

Xylem K+ loading modulates K+ and Cs+ absorption and distribution in Arabidopsis under K+-limited conditions

open access: yesFrontiers in Plant Science, 2023
Potassium (K+) is an essential macronutrient for plant growth. The transcriptional regulation of K+ transporter genes is one of the key mechanisms by which plants respond to K+ deficiency. Among the HAK/KUP/KT transporter family, HAK5, a high-affinity K+

Minimum K-S estimator using PH-transform technique [PDF]

open access: yesSuan Sunandha Rajabhat University Journal of Science and Technology, 2016
In this paper, we propose an improvement of the Minimum Kolmogorov-Smirnov (K-S) estimator using proportional hazards transform (PH-transform) technique. The data of experiment is 47 fire accidents data of an insurance company in Thailand.

Analysis of a Model for Generating Weakly Scale-free Networks [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
It is commonly believed that real networks are scale-free and fraction of nodes $P(k)$ with degree $k$ satisfies the power law $P(k) \propto k^{-\gamma} \text{ for } k > k_{min} > 0$.

Multi-radar fusion technique for high-resolution ISAR imaging in sea-cluttered environment

open access: yesThe Journal of Engineering, 2019
Radar imaging of the ship is one of the important means for surveillance and reconnaissance of targets. Here, the K-distribution is used for the statistical characterisation of echo model in sea-clutter environment.

Sampling Distribution for the K-Th Order Statistics from the Generalized Gumbel Distribution [PDF]

open access: yesThe Egyptian Statistical Journal, 2004
This article is concerned with the sampling distribution of the k-th order statistics of the generalized Gumbel distribution with one shape parameter 2 suggested by Adeyemi (2002). Focusing on the moments for the k-th order statistics numerical solutions

Angular analysis of the low K+K− invariant mass enhancement in B+→K+K−π+ decays

open access: yes, 2023
We study the decay B+→K+K−π+ and investigate the angular distribution of K+K− pairs with invariant mass below 1.1 GeV/c2. This region exhibits both a strong enhancement in signal and very large direct CP violation.

Pharmacokinetics of Two Chlorine-Substituted Bis-Pyridinium Mono-Aldoximes with Regenerating Effect on Butyrylcholinesterase

open access: yesMolecules, 2020
Our aim was to find chlorine-substituted antidotes against organophosphate poisoning and compare their pharmacokinetics to their parent compound, K-203. White male Wistar rats were intramuscularly injected with K-203, K-867 or K-870.
