Pteris madhusoodananii (Pteridaceae), a new fern species from India

Nordic Journal of Botany, EarlyView.
Pteris madhusoodananii sp. nov. (Pteridaceae), from the Kolli hills of Eastern Ghats, India, is described. The new taxon is morphologically distinct, characterized by a unique lamina texture and coloration, specific pinna‐pinnule architecture and distinct spore micromorphology.

Circumference, Minimum Degree and Clique Number

The Electronic Journal of Combinatorics
The circumference and the clique number of a graph is the length of a longest cycle and the largest order of a clique in it respectively. We show that the circumference of a 2-connected non-Hamiltonian graph $G$ is at least the sum of its clique number and minimum degree unless $G$ is one of two specific graphs.

Sources of Strength for School‐Based Suicide Prevention: Key Implementation Strategies Based on School Professional Perspectives

Psychology in the Schools, EarlyView.
ABSTRACT As concerns for rising rates of youth suicide and suicidal thoughts and behaviors continue to grow, there is a need to prioritize school‐based suicide prevention programs. Despite evidence documenting the effectiveness of school‐based prevention programs for reducing suicide‐related risk in adolescents, schools face numerous barriers to ...

Protosappanin A Alleviates Atherosclerosis by Regulating the MDM2/GPX4 Axis‐Mediated Endothelial Ferroptosis

Phytotherapy Research, EarlyView.
PTA alleviates atherosclerosis by regulating the MDM2/GPX4 axis‐mediated endothelial ferroptosis. ABSTRACT Endothelial ferroptosis is a crucial pathogenic driver of atherosclerosis (AS) progression. Protosappanin A (PTA), a bioactive compound from Caesalpinia sappan L., protects cardiovascular vessels by regulating ferroptosis.

Dynamic Cell Division for Interference Management in Satellite Direct‐to‐Cell Systems

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Direct‐to‐cell (D2C) connectivity enables future non‐terrestrial networks to provide service directly to standard terrestrial user equipment (UE) when terrestrial networks (TN) are unavailable. In this work, the satellite system is considered as a secondary network that supplements existing TN coverage while minimizing interference to the ...

Characterizing Large Clique Number in Tournaments

CoRR
Aboulker, Aubian, Charbit, and Lopes (2023) defined the clique number of a tournament to be the minimum clique number of one of its backedge graphs. Here we show that if $T$ is a tournament of sufficiently large clique number, then $T$ contains a subtournament of large clique number from one of two simple families of tournaments.

Fragmentation Across Scales, Geography, and Climate Challenges in European Urban Climate Change Adaptation and Mitigation Research: A Bibliometric and Systematic Review

Sustainable Development, EarlyView.
ABSTRACT European urban climate change research lacks integration across scales, geography, and climate challenges, despite Europe's coordinated policy frameworks. Through a hybrid bibliometric and systematic review of 1528 studies (2010–2025) using Cortext Manager and PRISMA 2020 guidelines, this study maps the conceptual patterns, knowledge gaps, and

Complexity Results on Graphs with Few Cliques

Discrete Mathematics & Theoretical Computer Science, 2007
A graph class has few cliques if there is a polynomial bound on the number of maximal cliques contained in any member of the class. This restriction is equivalent to the requirement that any graph in the class has a polynomial sized intersection ...

Empowering Consumer Participation in Energy Systems: A Comprehensive Analysis of Consumer Archetypes and Their Satisfaction Metrics in Germany

Sustainable Development, EarlyView.
ABSTRACT Active consumer participation is widely regarded as a key enabler of the energy transition, with emerging digital technologies creating new opportunities for engagement. However, these technologies only contribute to sustainable development if they are perceived as beneficial by diverse consumer groups.
