Connected graph searching in chordal graphs

Discrete Applied Mathematics, 2009
Graph searching was introduced by Parson [T. Parson, Pursuit-evasion in a graph, in: Theory and Applications of Graphs, in: Lecture Notes in Mathematics, Springer-Verlag, 1976, pp. 426--441]: given a “contaminated†graph G (e.g., a network containing a hostile intruder), the search number View the MathML source of the graph G is the minimum number ...

Structural behavior of deteriorated Gerber half‐joints in highway overpasses by nonlinear finite element analysis combined with a simplified uniform‐corrosion model

Structural Concrete, EarlyView.
Abstract Gerber half‐joints, broadly used in the last century as elements of concrete bridges, are prone to corrosion‐induced deterioration, which may lead to brittle shear collapse. It is of paramount importance to develop advanced numerical models for simulating the collapse behavior of Gerber half‐joints, taking material deterioration into account ...

Precipitation and female experience are major determinants of the breeding performance of Canarian houbara bustards

Wildlife Biology, EarlyView.
Precipitation is one of the main triggers of reproduction in desert‐breeding birds. The unpredictability of rainfall patterns in arid environments has led species to adapt their breeding effort to episodes of abundant food after rainfall. The response is not the same for all individuals in a population, and may vary especially with the age and ...

Hedgehogs and Angiostrongylus cantonensis: Uncovering the Role of Atelerix albiventris in the Parasite Life Cycle

Integrative Zoology, EarlyView.
ABSTRACT The ongoing invasion of the zoonotic parasite Angiostrongylus cantonensis threatens humans, other mammals, and birds. In Mallorca, neurological disorders associated with this parasite are increasingly reported in free‐living Algerian hedgehogs, Atelerix algirus, raising public health concerns.

Intermittent Fasting Enhances Motor Coordination Through Myelin Preservation in Aged Mice

Aging Cell, Volume 24, Issue 5, May 2025.
Over a 10‐week regimen, IMF significantly improved locomotor activity, motor coordination, and muscle strength compared to controls (p < 0.01). Resting‐state fMRI (rsfMRI) demonstrated that IMF modulates brain‐wide functional connectivity, enhancing communication between key brain regions.

Deciphering Novel Communication Patterns in T Regulatory Cells From Very Old Adults

Aging Cell, EarlyView.
Graphical summary depicting the changes in the co‐receptor landscape (a), migratory potential (b), differentiation program (c) and communication networks (d) in Tregs from the ‐< 66‐year‐old cohort versus the 85‐year‐olds. ABSTRACT Regulatory T cells (Tregs) are important in maintaining tolerance and are key players in immunity.

Deciphering Immunosenescence From Child to Frailty: Transcriptional Changes, Inflammation Dynamics, and Adaptive Immune Alterations

Aging Cell, EarlyView.
Integrated analysis of bulk‐cell and single‐cell RNA‐seq data from childhood to frailty revealed nonlinear transcriptomic changes in peripheral blood mononuclear cells, marked by dramatic early‐life shifts in inflammation, myeloid cells, and lymphocyte features, followed by stability in healthy elderly individuals.

Hippo pathway effectors are associated with glioma patient survival, control cell proliferation and sterol metabolism through TEAD3

Brain Pathology, EarlyView.
The Hippo pathway transcription factor TEAD3 represents an independent prognostic biomarker of tumor recurrence and a potential therapeutic vulnerability through its regulation of cholesterol metabolism in glioma. Abstract Glioblastomas represent the most common and lethal primary brain tumors in the world.

New graph classes characterized by weak vertex separators and two-pairs

AKCE International Journal of Graphs and Combinatorics, 2017
A set of vertices whose deletion from a graph would increase the distance between two remaining vertices is called a weak vertex separator of the graph. Two vertices form a two-pair if all chordless paths between them have length .
