Characterization of Graphs Without Even F $F$‐Orientations

Journal of Graph Theory, EarlyView.
ABSTRACT A graph G $G$ is 1‐extendable if every edge belongs to at least one 1‐factor of G $G$. Let G $G$ be a graph with a 1‐factor F $F$. Then an even (odd) F $F$ ‐orientation of G $G$ is an orientation in which each F $F$‐alternating cycle has exactly an even (odd) number of edges directed in the same fixed direction around the cycle.

Even Vertex Odd Mean Labeling of Graphs [PDF]

A graph with ???? vertices and ???? edges is said to have an even vertex odd mean labeling if there exits an injective function ????: ????(????) ⟶ { 0,2,4, … . , 2???? − 2,2????} such that the induced map ????∗: ????(????) ⟶ {1,3,5, … 2????

Liberation Through Narration: A Novel Humanistic Framework to Address Body Dissatisfaction

The Journal of Humanistic Counseling, EarlyView.
ABSTRACT Though body dissatisfaction is nuanced and pervasive, the magnitude of body dissatisfaction is undercut by essentialist conceptualizations of the body and medicalized metrics of wellness tied to disordered eating. Hence, there is a need for a contextualized and sustaining framework to address and promote healing from body dissatisfaction ...

Perspectives of High‐Resolution Mass Spectrometry in Soil Science

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Soil biogeochemical research requires specific, sensitive, and accurate methods to identify and quantify organic molecules in order to trace biochemical processes and assess element cycling in complex, heterogenous systems. High‐resolution mass spectrometry (HRMS) has evolved into a transformative tool for unraveling the complex chemical ...

Analytic odd mean labeling of union and identification of some graphs

, 2023
A graph G is analytic odd mean if there exist an injective function f  : V → {0, 1, 3, . . . , 2q − 1} with an induced edge labeling f∗ : E → Z such that for each edge uv with f(u) < f(v), is injective. Clearly the values of f∗ are odd. We say that f

Revealing the Resonant Physics of Open Photonic Time Crystals

Laser &Photonics Reviews, EarlyView.
ABSTRACT Photonic time crystals (PTCs) are media whose permittivity is modulated periodically in time, enabling momentum bandgaps and parametric amplification of light. Their realization at the nanoscale can revolutionize the study of light‐matter interactions.

Deuterium Quadrupolar Coupling Constants for Characterization of Hydrogen Ligands in Transition Metal Hydride Complexes: A Review

Magnetic Resonance in Chemistry, EarlyView.
An overview of the 2H NMR application shows how to use the DQCC values in metal–hydrogen systems for characterization of metal–hydrogen bonding modes in transition metal hydride complexes, metal–hydrogen alloys, metal nanoparticles, and immobilized metal hydrides.

Odd vertex equitable even labeling of graphs

, 2017
In this paper, we introduce a new labeling called odd vertex equitable even labeling. Let G be a graph with p vertices and q edges and A = {1, 3,..., q} if q is odd or A = {1, 3,..., q + 1} if q is even. A graph G is said to admit an odd vertex equitable

The role of identification in data‐driven policy iteration: A system theoretic study

International Journal of Robust and Nonlinear Control, EarlyView.
Abstract The goal of this article is to study fundamental mechanisms behind so‐called indirect and direct data‐driven control for unknown systems. Specifically, we consider policy iteration applied to the linear quadratic regulator problem. Two iterative procedures, where data collected from the system are repeatedly used to compute new estimates of ...

Discovery and Fine‐Scale Mapping of Hadal Xenophyophore Habitat in the Nova Canton Trough, Central Pacific Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
Discovery and fine‐scale mapping of a hadal xenophyophore field: submersible video transects and photogrammetry enable semi‐automated delineation of xenophyophores, revealing their abundance, spatial organisation, structural complexity and contribution to habitat heterogeneity at ~8000 m depth.
