The Fractal Calculus for Fractal Materials

Fractal and Fractional, 2019
The major problem in the process of mixing fluids (for instance liquid-liquid mixers) is turbulence, which is the outcome of the function of the equipment (engine). Fractal mixing is an alternative method that has symmetry and is predictable.

Minkowski dimension and explicit tube formulas for $p$-adic fractal strings

, 2018
The local theory of complex dimensions describes the oscillations in the geometry (spectra and dynamics) of fractal strings. Such geometric oscillations can be seen most clearly in the explicit volume formula for the tubular neighborhoods of a $p$-adic ...

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

Aggregate, 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

Computational identification of antibody-binding epitopes from mimotope datasets

Frontiers in Bioinformatics
Introduction: A fundamental challenge in computational vaccinology is that most B-cell epitopes are conformational and therefore hard to predict from sequence alone. Another significant challenge is that a great deal of the amino acid sequence of a viral

A Smooth Curve as a Fractal Under the Third Definition

, 2018
It is commonly believed in the literature that smooth curves, such as circles, are not fractal, and only non-smooth curves, such as coastlines, are fractal.

In Situ Graph Reasoning and Knowledge Expansion Using Graph‐PRefLexOR

Advanced 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.

The Fractal Dimension of Projected Clouds

, 2005
The interstellar medium seems to have an underlying fractal structure which can be characterized through its fractal dimension. However, interstellar clouds are observed as projected two-dimensional images, and the projection of a tri-dimensional fractal

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

Advanced 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

Looking under the lamp-post: quantifying the performance of contact tracing in the United States during the SARS-CoV-2 pandemic

BMC Public Health
Contact tracing forms a crucial part of the public-health toolbox in mitigating and understanding emergent pathogens and nascent disease outbreaks. Contact tracing in the United States was conducted during the pre-Omicron phase of the ongoing COVID-19 ...

The role of right-lateral shear zone and folding-related fractures in development of Zarshuran gold deposit, Takht-e-Soleyman complex, northern Takab

Journal of Economic Geology, 2020
Introduction The Zarshuran gold deposit is located in the Takht-e-Soleyman complex, NW Iran. It is formed in the Iman Khan NW-trending anticline (Mehrabi et al., 1999; Samimi, 1992).
