Globally Anisotropic High Porosity Silica Aerogels
, 2007 We discuss two methods by which high porosity silica aerogels can be engineered to exhibit global anisotropy. First, anisotropy can be introduced with axial strain.

Advanced Science, EarlyView.We report, for the first time, an external electric field (EEF) strategy to achieve co‐aggregation of conjugated polymer blends (i.e., poly(3‐butylthiophene) and poly[3,3'''‐dialkyl‐quaterthiophene]s) in the solution and thus their cocrystals in thin films, demonstrating cocrystal‐improved charge mobilities due to the synergy of two components ...

Fractal image compression [PDF]
Fractals are geometric or data structures which do not simplify under magnification. Fractal Image Compression is a technique which associates a fractal to an image. On the one hand, the fractal can be described in terms of a few succinct rules, while on

A statistical reduced-reference method for color image quality assessment
, 2014 Although color is a fundamental feature of human visual perception, it has been largely unexplored in the reduced-reference (RR) image quality assessment (IQA) schemes.

Reconfigurable Acoustofluidic Microvortices for Selective Microcargo Delivery
Advanced Science, EarlyView.This work introduces a frequency‐encoded, reconfigurable acoustofluidic system that overcomes the low throughput and poor selectivity of conventional micro‐delivery methods. By exploiting discrete microbubble resonances to program adaptive microvortex modes, the platform enables real‐time switching and selective guidance of microscale payloads through ...

A Fast Fractal Image Compression Method Based Entropy
ELCVIA Electronic Letters on Computer Vision and Image Analysis, 2005 Fractal image compression gives some desirable properties like resolution independence, fast decoding, and very competitive rate-distortion curves. But still suffers from a (sometimes very) high encoding time, depending on the approach being used.

Advanced Intelligent Discovery, EarlyView.CrossMatAgent is a multi‐agent framework that combines large language models and diffusion‐based generative AI to automate metamaterial design. By coordinating task‐specific agents—such as describer, architect, and builder—it transforms user‐provided image prompts into high‐fidelity, printable lattice patterns.

Myocardial Perfusion Defects in Hypertrophic Cardiomyopathy Mutation Carriers
Journal of the American Heart Association, EarlyView., 2021 Background Impaired myocardial blood flow (MBF) in the absence of epicardial coronary disease is a feature of hypertrophic cardiomyopathy (HCM). Although most evident in hypertrophied or scarred segments, reduced MBF can occur in apparently normal segments.
