A Novel Anatomical Description of the Normal Terminal Fibular Artery and the Terminal Fibular Window: Radiological Findings and Surgical Implications

Clinical Anatomy, EarlyView.
ABSTRACT A novel anatomical description and radiological finding, related to the anatomical course of the terminal fibular artery (FibA) was recently reported. In the article, the authors found the terminal FibA to change its course, from being posterior and medial to the fibula to surface anteriorly and laterally before residing below the tibiofibular

Guided Toward Equity: Communities of Practice and Organizational Change in Community Colleges

New Directions for Community Colleges, EarlyView.
ABSTRACT Although community colleges advance equity by providing opportunities for marginalized students to pursue higher education, barriers to earning credentials remain, particularly for students of color. Higher education stakeholders are investing in “equity work” as organizations take responsibility for ensuring equitable outcomes.

Some notes on the Roman domination number and Italian domination number in graphs

Journal of Physics: Conference Series, 2017
An Italian dominating function (or simply, IDF) on a graph G = (V, E) is a function f : V → {0, 1, 2} that satisfies the property that for every vertex v ∈ V, with f(v) = 0, Σ u∈N(v) f(u) ≥ 2. The weight of an Italian dominating function f is defined as w(f) = f(V ) = Σ u∈V f(u).

Roman domination in graphs [PDF]

, 2003
A Roman dominating function on a graph G=(V,E) is a function f:V→{0,1,2} satisfying the condition that every vertex u for which f(u)=0 is adjacent to at least one vertex v for which f(v)=2.

Syntheses and Properties of Pentafluoroethylplumbanes in the Oxidation States +II, +III, and +IV

Chemistry – A European Journal, EarlyView.
Syntheses of pentafluoroethyl substituted plumbanes in the formal oxidation states +II, +III, and +IV are reported. The compounds were characterized by multinuclear NMR spectroscopy, including 207Pb NMR spectroscopy, mass spectrometry and single‐crystal x‐ray diffraction experiments. ABSTRACT Mono‐, bis‐, and tris(pentafluoroethyl)plumbanes of the type

Varieties of Roman domination IV

AKCE International Journal of Graphs and Combinatorics
Roman domination was introduced in 2004 by Cockayne, Dreyer, Hedetniemi, and Hedetniemi. If [Formula: see text] is the vertex set of a graph G, then a function [Formula: see text] is a Roman dominating function if every vertex [Formula: see text] for ...

Photoinduced ROS Production by Poly(3‐hexylthiophene) (P3HT) is due to Autoxidation Rather Than Catalysis

Chemistry – A European Journal, EarlyView.
P3HT is widely treated as a photocatalyst that generates ROS under light. We show otherwise: ROS production comes at the expense of the polymer itself. Photoexcited P3HT acts as a self‐sacrificial photosubstrate, undergoing irreversible autoxidation during light‐driven oxygen reduction—a distinction critical for interpreting its behavior in emerging ...

Bounds on the global double Roman domination number in graphs [PDF]

Let $G$ be a simple graph of order $n$ and let $\gamma_{gdR}(G)$ be the global double Roman domination number of $G$. In this paper, we give some upper bounds on the global double Roman domination number of $G$.

Development of a Mechanically Regenerating Desublimator for Freeze‐Drying Systems in the Food Industry

Chemie Ingenieur Technik, EarlyView.
Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.
