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.

On the k-gamma q-distribution

open access: yesOpen Mathematics, 2010
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.

The distribution of $k$-free numbers [PDF]

open access: yesMathematics of Computation, 2020
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

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+

Distributed k-core decomposition [PDF]

open access: yesProceedings of the 30th annual ACM SIGACT-SIGOPS symposium on Principles of distributed computing, 2011
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]

open access: yesStatistical Analysis and Data Mining: The ASA Data Science Journal, 2018
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]

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 $P(k) \propto k^{-\gamma} \text{ for } k > k_{min} > 0$.

Distributed top-k monitoring [PDF]

open access: yesProceedings of the 2003 ACM SIGMOD international conference on on Management of data - SIGMOD '03, 2003
The querying and analysis of data streams has been a topic of much recent interest, motivated by applications from the fields of networking, web usage analysis, sensor instrumentation, telecommunications, and others. Many of these applications involve monitoring answers to continuous queries over data streams produced at physically distributed ...

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
