Induced Cycles and Chromatic Number

Journal of Combinatorial Theory, Series B, 1999
The author proves that for any pair of positive integers \(r\) and \(s\), there exists an integer \(N(r,s)\) such that every graph with chromatic number at least \(N(r,s)\) contains either the complete graph \(K_r\) or an induced odd cycle of length at least 5 or an induced cycle of length at least \(s\).

VALIANT: A Vision‐Authenticity Language Framework Through Integrated Experts and Aligned Numerical‐Textual Descriptors for Citri Reticulatae Pericarpium

Advanced Intelligent Systems, EarlyView.
Visual features, numerical descriptors, and controlled textual attributes extracted from smartphone images of Chenpi are integrated by VALIANT, a tailored multimodal framework for simultaneous storage‐age classification and authenticity verification. The workflow distinguishes genuine products from suspicious standard operating procedure mimics while ...

Dissecting Pirtobrutinib Resistance in Mantle Cell Lymphoma Through Single‐Cell Multi‐Omics

American Journal of Hematology, EarlyView.
ABSTRACT Pirtobrutinib (PBN), a non‐covalent BTK inhibitor, has been approved by the FDA for relapsed/refractory mantle cell lymphoma (MCL); however, resistance to PBN has been observed. To dissect the molecular dynamics driving PBN resistance, we performed integrative single‐cell multi‐omic profiling (scRNA‐seq, scATAC‐seq, and scDNA‐seq) on ...

Light‐Responsive Carbon Dots with Photochromism and Excitation‐Dependent Room Temperature Phosphorescence

Advanced Physics Research, EarlyView.
A light‐responsive system with photochromism and excitation‐dependent phosphorescence was constructed by microwave synthesis of nitrogen‐doped carbon dots(N‐CDs), which provides insights into the design and synthesis of CDs with multifunctional optical properties, promoting the application expansion of intelligent responsive materials in the fields of ...

Metalens‐Enabled Twisted Chromatic Dispersion

Advanced Physics Research, EarlyView.
We successfully demonstrate visible broadband twisted dispersion metalenses. As a proof of concept, we realized two distinct devices: the conical helical and the spring‐like dispersion‐controlled metalenses. These results rigorously validate the universality of our approach in customizing arbitrary continuous 3D dispersion trajectories, thereby ...

Design of experiments‐driven optimization of Porphyridium marinum cultivation: impact of operational variables on phycoerythrin and exopolysaccharide production

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Among the Porphyridium genus, Porphyridium marinum exhibits the highest phycoerythrin (PE) content. In this study, the metabolic trade‐off between biomass, PE, and sulfated exopolysaccharide (EPS) production was assessed under varying nitrogen and sulfur availability, light intensity, residence time, and cultivation mode.

2D copper nanozyme patches facilitate bone regeneration via interfacial modulation of osteoclast‐osteoblast dynamics

BMEMat, EarlyView.
This study develops a nano‐enzyme patch (ezPatch) targeting bone interfaces. Utilizing ligand‐to‐metal charge transfer (LMCT) catalysis and bone‐targeting ligands on copper nanosheets, ezPatch simultaneously scavenges reactive oxygen species (ROS) and generates oxygen in situ at bone‐losing sites.

Productivity and Emissions in Italian Agriculture: A Farm‐Level Efficiency Analysis

Business Strategy and the Environment, EarlyView.
ABSTRACT Achieving the European Union climate‐neutrality objectives requires metrics that jointly assess farm productivity and greenhouse gas emissions at a granular level. However, harmonized evidence for benchmarking the productivity–emissions nexus of Italian farms remains limited.

Design of a Fluorescent Boronic Acid‐Functionalized Pyranoflavylium Receptor to Host and Release Diol‐Rich Bioactive Analytes in a pH‐Dependent Manner

ChemFoodChem, EarlyView.
This work presents a pH‐responsive ON–OFF fluorescent system based on a novel pyranoflavylium dye functionalized with a boronic acid receptor. The receptor exhibits a markedly higher affinity for the catechol‐containing polyphenol (+)‐catechin than for conventional diol‐rich molecules such as glucose and lactic acid.
