Integer-Magic Spectra of Sun Graphs

open access: yes, 2013
國科會研究計畫:NSC 98-2115-M-032-005-MY3Let N be the set of all positive integers, and Zn={0, 1, 2, …, n-1}. For any h ∈ N, a graph G=(V,E) is said to be Zh-magic if there exists a labeling f : E → Zh\{0} such that induced vertex labeling f+ : V → Zh, defined ...

On magic joins of graphs [PDF]

open access: yes, 2010
summary:A graph is called magic (supermagic) if it admits a labeling of the edges by pairwise different (and consecutive) integers such that the sum of the labels of the edges incident with a vertex is independent of the particular vertex.

Make Social Media Social Again: How Platform Interoperability Can Fix Social Media and Future‐Proof Democracy

open access: yesJournal of Management Studies, EarlyView.
Abstract This essay argues that social media document (rather than fuel) the decline of political democracy while helping revive organizational democracy, including through ‘decentralized autonomous organizations’ (DAOs). Yet, despite giving everyone a voice and the ability to organize across borders, social media could over‐concentrate power if, in ...

Local inclusive distance antimagic coloring of graphs

open access: yesIndonesian Journal of Combinatorics
For a simple graph G, a bijection f : V(G) → [1,|V (G)|] is called as a local inclusive distance antimagic (LIDA) labeling of G if w(u) ≠ w(v) for every two adjacent vertices u,v ∈ V(G) with w(u) = ∑x∈N [u] f(x).

The MexMAGIC population reveals the genetic architecture of traits exhibiting clinal variation in Mexican native maize

open access: yesNew Phytologist, EarlyView.
The MexMAGIC population mixes native maize varieties from across Mexico to study functional genetic diversity. Summary Defining the genetic basis of local adaptation is a key goal of evolutionary biology and crop improvement. Theory predicts that when selective pressures follow differences in the environment, a cline will be established.

On local distance antimagic labeling of graphs

open access: yesAKCE International Journal of Graphs and Combinatorics
Let [Formula: see text] be a graph of order n and let [Formula: see text] be a bijection. For every vertex [Formula: see text], we define the weight of the vertex v as [Formula: see text] where N(v) is the open neighborhood of the vertex v. The bijection

Unexpected Suppression of Tomato Fruit Cuticle Formation by Overexpression of a Key Cutin Biosynthetic Enzyme

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Fruit cuticles regulate the diffusion of water, gases and solutes, functioning as essential protective interfaces against environmental and biotic stresses. Engineering cuticle structure and mechanics therefore represents a promising strategy for improving fruit quality and resilience.

Infinite Ends From Finite Samples: Open‐Ended Goal Inference as Top‐Down Bayesian Filtering of Bottom‐Up Proposals

open access: yesTopics in Cognitive Science, EarlyView.
Abstract The space of human goals is tremendously vast; and yet, from just a few moments of watching a scene or reading a story, we seem to spontaneously infer a range of plausible motivations for the people and characters involved. What explains this remarkable capacity for intuiting other agents' goals, despite the infinitude of ends they might ...

On Structural and Spectral Properties of Distance Magic Graphs

open access: yes, 2023
A graph $G=(V,E)$ is said to be distance magic if there is a bijection $f$ from a vertex set of $G$ to the first $|V(G)|$ natural numbers such that for each vertex $v$, its weight given by $\sum_{u \in N(v)}f(u)$ is constant, where $N(v)$ is an open neighborhood of a vertex $v$. In this paper, we introduce the concept of $p$-distance magic labeling and
