Superelastic Fire‐Safe Aerogel with Hierarchical Structures via Dual Templates Aided by Microbubble Engineering

open access: yesAdvanced Science, EarlyView.
Here, a dual‐template strategy (ice and bubble template) is used to prepare fire‐safe aerogels with hierarchical structures. When the foam expansion ratio exceeds the jamming transition value in the foam system, the aerogels demonstrate superelasticity and extreme shape adaptability.

A General Strategy to Fine‐Tune Group 14 Rhodamines for Ultrahigh Signal‐to‐Noise Ratio Labeling In Vivo by Nano‐Aggregation

open access: yesAggregate, EarlyView.
Group 14 rhodamines are one of the most widely explored fluorogenic probes with high signal‐to‐noise ratio (SNR). We have boosted the SNR of group 14 rhodamines by nano‐aggregation via a novel strategy by manipulating their dynamic physical and chemical states for the first time. The ultrahigh SNR fluorescence imaging offers a fundamental understanding

Review of Fractal and Fractal Derivatives in relation to the Physics of Fractals

open access: yes, 2013
Fractional and fractal derivatives are both generalizations of the usual derivatives that consider derivatives of non-integer orders. Interest in these generalizations has been triggered by a resurgence of clamor to develop a mathematical tool to describe “roughness” in the spirit of Mandelbrot’s (1967) Fractal Geometry. Fractional derivatives take the

In Situ Graph Reasoning and Knowledge Expansion Using Graph‐PRefLexOR

open access: yesAdvanced Intelligent Discovery, EarlyView.
Graph‐PRefLexOR is a novel framework that enhances language models with in situ graph reasoning, symbolic abstraction, and recursive refinement. By integrating graph‐based representations into generative tasks, the approach enables interpretable, multistep reasoning.

Fractal Surfaces

open access: yesJournal of Mathematical Analysis and Applications, 1990
Publisher Summary This chapter discusses IRm -valued multivariate continuous fractal functions and some of their properties. It presents tensor product fractal surfaces and the way tensor product can be used to obtain fractal-like surfaces from univariate IR-valued continuous fractal functions.

Machine‐Learning‐Guided Analysis of Breast Tumor Malignancy Based on Nuclear Morphological Features

open access: yesAdvanced Intelligent Discovery, EarlyView.
Through statistical and machine learning approaches, we evaluate a clinically relevant dataset comprising more than 500 instances of patient breast tumor nuclei with 10 size and shape features. Our study underscores the significance of nuclear morphological features as potential breast tumor malignancy biomarkers and their combined use with statistical

Fractales

open access: yesTecnología en Marcha, 2016
Una forma de modelar muchos objetos de la naturaleza, con características irregulares, fragmentadas y con una variedad infinita de detalle es logrado utilizando la geometría utilizada por Benoit B. Mandelbrot, quien la designó con el nombre de geometría fractal.

Fractal statistics [PDF]

open access: yesChaos, Solitons & Fractals, 2001
We consider the recent description of elementary particles in terms of Quantum Mechanical Kerr-Newman Black Holes, a description which provides a rationale for and at the same time reconciles the Bohm-hydrodynamical formulation on the one hand and the Nelsonian stochastiic formulation on the other.

Liquid Metal Reversible Contacts for Flexible Tactile Sensor with High Sensitivity and Wide Detection Range

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents a novel flexible tactile sensor based on the unconventional reversible contact behavior between liquid metal droplets (LMDs), with high‐pressure sensitivity and a broad working range. The 2‐LMD‐based sensor is capable of monitoring human motion and physiological signals, while electrical impedance tomography enables precise shape and

Perceptual and physiological responses to Jackson Pollock’s fractals

open access: yesFrontiers in Human Neuroscience, 2011
Fractals have been very successful in quantifying the visual complexity exhibited by many natural patterns, and have captured the imagination of scientists and artists alike.
