On 14-regular distance magic graphs
Electronic Journal of Graph Theory and ApplicationsLet G be a graph with n vertices. By N(v) we denote the set of all vertices adjacent to v. A bijection f : V(G)→{1, 2, …, n} is a distance magic labeling of G if there exists an integer k such that the sum of labels of all vertices adjacent to v is k for

Magic labelings of distance at most 2
, 2013 For an arbitrary set of distances $D\subseteq \{0,1, \ldots, d\}$, a graph $G$ is said to be $D$-distance magic if there exists a bijection $f:V\rightarrow \{1,2, \ldots , v\}$ and a constant {\sf k} such that for any vertex $x$, $\sum_{y\in N_D(x)} f(y) ={\sf k}$, where $N_D(x) = \{y \in V| d(x,y) \in D\}$.

Advanced Science, EarlyView.ABSTRACT Brown and beige adipocytes dissipate energy as heat, yet effective strategies to enhance their mitochondrial efficiency remain limited. Here, we identify Agnuside (AGN) as a selective stabilizer of the complex I assembly factor NDUFAF6. AGN directly binds cytosolic NDUFAF6, suppresses its ubiquitination, prolongs its half‐life, and facilitates

Children &Society, EarlyView., 2023 Abstract As a primary source for the early ages, picture books guide preschool children's gender perception through stories and illustrations. However, previous studies have criticised an overall gender inequality in children's picture books. Compared to the increasing attention on gender diversity in the UK picture book industry, there has been little

Tetravalent distance magic graphs of small order and an infinite family of examples [PDF]
, 2023 A graph of order $n$ is distance magic if it admits a bijective labeling of its vertices with integers from $1$ to $n$ such that each vertex has the same sum of the labels of its neighbors.

Electrohydraulic Folding Ring Actuators for Radially Contracting Applications
Advanced Science, EarlyView.This work presents an Electrohydraulic Folding Ring Actuator that combines high‐performance electrohydraulic actuation with origami‐inspired folding geometry to achieve constricting radial actuation. This integration yields significant inner lumen constriction, alongside a gripping force capable of holding objects exceeding four times the actuator's ...

Distance magic labelings of graphs [PDF]
, 2013 Razdaljno magično označevanje grafa je bijekcija f : V -> {1, 2,...,n}, z lastnostjo, da obstaja taka konstanta k, da za vsako vozlišče x grafa velja, f(x_1)+f(x_2)+...+f(x_j)= k, kjer je y_i (i = 1,...,j) iz odprte okolice vozlišča x.

Tailored D‐π Conjugation Boosts Piezocatalytic CO2 Reduction in a Platinum(II)‐Acetylide Framework
Advanced Science, EarlyView.The highly conjugated metalII‐acetylide framework demonstrates efficient ultrasound‐driven conversion of CO2 to CO. The piezoelectric field generated by ultrasound facilitates electron transfer from the tetraphenylene π‐column to the MII‐bis(acetylide) moiety, enabling CO2 activation. Compared to PdII‐ and NiII‐based analogues, the stronger d–π orbital

Advanced Science, EarlyView.This study presents a surfaceome‐reprogramming strategy for mutation‐independent lung cancer therapy by repurposing dexamethasone to prime mesenchymal stem cell‐derived nanovesicles. The engineered vesicles leverage multi‐valent interactions mediated by upregulated adhesion proteins, EPHA2, and NOTCH3.
