Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Inhaled Angiopoietin‐Like 4 Antisense Oligonucleotide Therapy for Lung Injury and Fibrosis

Advanced Science, EarlyView.
Inhaled antisense oligonucleotides targeting ANGPTL4 attenuate inflammation, preserve barrier integrity, and reduce fibrosis in both infectious and sterile lung injury models. Integrated transcriptomic analysis reveals a conserved ANGPTL4‐regulated gene network coordinating hypoxic, inflammatory, apoptotic, and stress‐response pathways.

DRD2 Deficiency Underlies Pituitary Adenoma Dependent on Escherichia coli Translocation from the Gut

Advanced Science, EarlyView.
Dopamine receptor D2 (DRD2) deficiency disrupts epithelial barrier integrity in both the gut and pituitary gland, facilitating translocation of gut‐derived Escherichia coli into pituitary tissue. Intratumoral E. coli are phagocytosed by microglia, triggering GSDMD‐dependent pyroptosis and HMGB1 release, which subsequently activates MAPK signaling to ...

Asymmetric tent map expansions II. Purely periodic points

Illinois Journal of Mathematics, 1994
This paper is a continuation of the first part [J. Lond. Math. Soc. 47, 542-556 (1993)] reviewed above. In the present paper the authors consider again the \(T_ \alpha\)-expansion of numbers \(x\in [0,1]\), where \(T_ \alpha\) is an asymmetric tent map \((\alpha>1)\).

Gut Microbiota‐Derived Anandamide Mediates the Therapeutic Effects of Urolithin A on Alcohol‐Induced Cognitive and Social Dysfunction via CB1R‐DRD2‐RAP1 Signaling Axis

Advanced Science, EarlyView.
This study reveals that Urolithin A (UA) counteracts alcohol‐induced cognitive and social dysfunction (AICSD) via a gut microbiome‐dependent mechanism. UA‐enriched Bacteroids sartorii and Parabacteroids distasonis elevate anandamide (AEA), which activates the CB1R‐DRD2‐Rap1 signaling cascade to drive synaptic repair and reduce neuroinflammation ...

A Novel Chaotic Map and an Improved Chaos-Based Image Encryption Scheme

The Scientific World Journal, 2014
In this paper, we present a novel approach to create the new chaotic map and propose an improved image encryption scheme based on it. Compared with traditional classic one-dimensional chaotic maps like Logistic Map and Tent Map, this newly created ...

A Novel Function of Nonadecanoic Acid in Regulating Glucose Homeostasis

Advanced Science, EarlyView.
This study identifies the odd‐chain fatty acid C19:0 as an endogenous ligand of GPR120 that promotes glucose homeostasis via Gαq signaling. In obesity, elevated palmitic acid suppresses endogenous C19:0 production through a miRNA–PPARα–HACL1 pathway, offering a promising direction for understanding the role of OCFAs in human health.

Image encryption scheme based on compressed sensing and fractional quantum logistic-tent map

Cybersecurity
In this paper, we construct a quantum logistic-tent map and extend it to the fractional order. Using bifurcation portrait, Lyapunov exponent spectrum, and spectral entropy, its nonlinear characteristics are investigated.
