Roman Domination in Weighted Graphs

Mathematics
A Roman dominating function for a (non-weighted) graph G=(V,E) is a function f:V→{0,1,2} such that every vertex u∈V with f(u)=0 has at least one neighbor v∈V such that f(v)=2.

Jewelled Byzantine and Medieval Reliquaries of the True Cross: Peridots and Other Gemstones in Material and Symbolic Perspective

Journal of Raman Spectroscopy, EarlyView.
An interdisciplinary in situ study of jewelled reliquaries of the True Cross integrates gemmology and portable analytical techniques, revealing new evidence on the identification and symbolic role of peridots and other gemstones. ABSTRACT Jewelled crosses containing relics of the True Cross occupy a central position in the devotional, artistic and ...

The Past, Present, and Future of Customer Knowledge Management: A Review and Research Agenda

Knowledge and Process Management, EarlyView.
ABSTRACT We develop and present a framework for research in customer knowledge management (CKM) that synthesizes insights from a comprehensive literature review spanning 2000 to 2024. This framework highlights the determinants, impacts, and moderators shaping CKM and its role in contemporary organizations.

Shaping Manager Well‐Being and Functioning in Declining Nonprofit Organizations: The Critical Role of Strategy Implementation

Nonprofit Management and Leadership, EarlyView.
ABSTRACT Under the roof of Christian churches in Central Europe, some nonprofit organizations (NPOs) grow, while others are in marked decline. Our study in this context extends a previous focus on financial indicators to NPO managers' experiences, their role clarity and job satisfaction, during phases of organizational growth and decline. Specifically,

Conflict-Free Colouring of Graphs [PDF]

, 2013
We study the conflict-free chromatic number χ CF of graphs from extremal and probabilistic points of view. We resolve a question of Pach and Tardos about the maximum conflict-free chromatic number an n-vertex graph can have.

The evaluation of boundary‐layer turbulence in high‐resolution numerical weather prediction simulations using Doppler lidar

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A new method compares both kilometer and sub‐kilometre weather model simulations with Doppler lidar observations to assess the representation of boundary‐layer turbulence. While bulk boundary‐layer properties are well represented, vertical velocity variance is strongly underestimated in both simulations.

Exploring the Use and Impact of Composite Materials in Robotics: A Systematic Review

Journal of Field Robotics, EarlyView.
ABSTRACT Lightweight and high‐strength materials are important in robotics, as structural design impacts efficiency, payload capacity, and energy consumption. Composite materials, with their superior stiffness‐to‐weight ratios and multifunctional properties, offer clear advantages over conventional metals and polymers.

Evaluating land–sea linkages using land cover change and coral reef monitoring data: A case study from northeastern Puerto Rico

Remote Sensing in Ecology and Conservation, EarlyView.
Land cover change that leads to increased nutrient and sediment runoff is an important driver of change in coral reef ecosystems. In this study, we combined satellite remote sensing and field monitoring to assess concomitant changes in watershed land cover and coral cover in northeastern Puerto Rico in 2000–2015.

Mapping Scytonemin Pigment Content and Biocrust Functional Indicators Using High‐Resolution Multispectral Imagery

Remote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution multispectral imagery combined with machine learning can accurately predict key biocrust functional indicators, particularly the UV‐protective pigment scytonemin, across dryland ecosystems. Using fine‐scale imagery acquired in the Chihuahuan Desert and Colorado Plateau, we identified spectral bands strongly ...

Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis

Structural Concrete, EarlyView.
Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.
