The 1 3 $\frac{1}{3}$‐Conjectures for Domination in Cubic Graphs

Journal of Graph Theory, EarlyView.
ABSTRACT A set S $S$ of vertices in a graph G $G$ is a dominating set of G $G$ if every vertex not in S $S$ is adjacent to a vertex in S $S$. The domination number of G $G$, denoted by γ ( G ) $\gamma (G)$, is the minimum cardinality among all dominating sets in G $G$. In a breakthrough paper in 2008, Löwenstein and Rautenbach proved that if G $G$ is a

The Minimal Nonplanar Strong Digraphs

Journal of Graph Theory, EarlyView.
ABSTRACT Kuratowski's theorem says that the minimal (under subgraph containment) graphs that are not planar are the subdivisions of K 5 ${K}_{5}$ and of K 3 , 3 ${K}_{3,3}$. Here we study the minimal (under subdigraph containment) strongly‐connected digraphs that are not planar.

A Structural Description of Zykov and Blanche Descartes Graphs

Journal of Graph Theory, EarlyView.
ABSTRACT Around 1950, Zykov and Blanche Descartes proposed the two first explicit constructions of triangle‐free graphs with arbitrarily large chromatic number. We define a Zykov (resp. Blanche Descartes) graph as any induced subgraph of a graph created using Zykov's construction (resp. Blanche Descartes's).

SubDIVIDE: Efficient tensor‐valued diffusion magnetic resonance imaging via joint diffusional variance decomposition modeling and subspace reconstruction

Journal of Intelligent Medicine, EarlyView.
SubDIVIDE integrates a physics‐consistent DIVIDE subspace directly into MRI reconstruction. By embedding a low‐rank basis derived from a large DIVIDE signal dictionary into a joint ADMM optimization—together with composite sensitivity maps that absorb inter‐b‐value phase errors—the framework recovers quantitative microstructural maps from highly ...

Food Security Versus Environmental Health: The Nitrogen Dilemma

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

Optical Stimulation and Monitoring of the Peripheral Nervous System: Perspectives and Challenges Toward Clinical Translation

Laser &Photonics Reviews, EarlyView.
Optical neuromodulation with IR light allows stimulation of the PNS without the need for physical contact with the target nerve or without requiring any genetic modification. The clinical translation of this technique will pave the way to the development of neural interfaces for restoring sensory feedback in individuals with limb amputation.

Development and Characterization of Liposomes Containing a Zn(II) Porphyrin Derivative for the Application of Photodynamic Therapy in the Treatment of Breast Cancer

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Objectives This study aims to synthesize and characterize lipid nanosystems (liposomes) for the incorporation of a Zn(II) porphyrin derivative, Zn(II) meso‐tetrakis(N‐n‐hexylpyridinium‐2‐yl)porphyrin (ZnTnHex‐2‐PyP4+, ZnPH), intending to employ an alternative method of treatment, such as photodynamic therapy (PDT), for breast cancer (BC ...

Boronic Acid Inhibitors of β‐Lactamases: A Promising Strategy Against Antimicrobial Resistance

Medicinal Research Reviews, EarlyView.
ABSTRACT The rise of antimicrobial resistance (AMR) poses a critical threat to global health, mostly due to the proliferation of β‐lactamases, a class of enzymes responsible for the inactivation of β‐lactam antibiotics. Among the most promising strategies to restore β‐lactam efficacy is the use of β‐lactamase inhibitors (BLIs), with boronic acid ...
