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

Abstract We provide combinatorial as well as probabilistic interpretations for the q-analogue of the Pochhammer k-symbol introduced by Díaz and Teruel. We introduce q-analogues of the Mellin transform in order to study the q-analogue of the k-gamma distribution.

A method for estimating the parameters of the K distribution
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.

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+

The distribution of $k$-free numbers [PDF]
Let $R_k(x)$ denote the error incurred by approximating the number of $k$-free integers less than $x$ by $x/ζ(k)$. It is well known that $R_k(x)=Ω(x^{\frac{1}{2k}})$, and widely conjectured that $R_k(x)=O(x^{\frac{1}{2k}+ε})$. By establishing weak linear independence of some subsets of zeros of the Riemann zeta function, we establish an effective proof

A Tool for Generating Fast k‐Distribution Gas‐Optics Models for Weather and Climate Applications
One of the most important components of an atmospheric radiation scheme is its treatment of gas optical properties, which determines not only the accuracy of its radiative forcing calculations fundamental to climate prediction, but also its computational

Distributed k-core decomposition [PDF]
Among the novel metrics used to study the relative importance of nodes in complex networks, k-core decomposition has found a number of applications in areas as diverse as sociology, proteinomics, graph visualization, and distributed system analysis and design.

Distribution‐preserving k‐anonymity [PDF]
Preserving the privacy of individuals by protecting their sensitive attributes is an important consideration during microdata release. However, it is equally important to preserve the quality or utility of the data for at least some targeted workloads. We propose a novel framework for privacy preservation based on the k‐anonymity model that is ideally ...

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