Operationalising Circular Economy Through Social Innovation: A Systems Thinking‐Based Model for Sustainability Transitions

open access: yesSustainable Development, EarlyView.
ABSTRACT Social innovation (SI) is increasingly recognised as an important enabler of circular economy (CE) transitions. However, existing research offers limited explanation of the processes through which SI operationalises CE principles, as SI and CE have largely evolved in parallel and existing conceptualisations remain predominantly descriptive ...

Enhancing Coherence Length in Tailored Chiral Hybrid Polymer‐Wrapped Single‐Walled Carbon Nanotube Superstructures

open access: yesSmall, EarlyView.
Conductance measurements demonstrate a fivefold enhancement in phase coherence length in a specially designed chiral polymer‐wrapped metallic single‐walled carbon nanotube (m‐SWNT) superstructure, relative to the corresponding achiral m‐SWNT benchmark.

Sustainability of Cash Waqf Development in Indonesia: A Quintuple Helix Perspective

open access: yesSains Humanika, 2016
The objective of this paper is to analyze the sustainability of cash waqf (endowment) development in Indonesia from a quintuple perspective. Waqf can be in the form of productive assets (either current or fixed) or non-productive fixed assets. The method of this research uses qualitative research based on a literature review and in-depth interview with

Position Over Composition: Positional Isomerism Enables Encapsulation‐Independent Intrinsic Stability in a Conjugated Polymer

open access: yesSmall, EarlyView.
Repositioning side chains (para→meta) provides a composition‐invariant handle to program conjugated‐polymer chain geometry. The resulting worm‐like, kink‐suppressed conformation delivers >5× higher intrinsic photostability and enhanced resistance to energetic particle damage.

The Sextuple Helix Innovation Model: Positioning Generative AI as an Epistemic Agent in Creative and Sustainable Knowledge Economies

open access: yesSocial Sciences
This paper introduces the Sextuple Helix Innovation Model as an extension of the Quintuple Helix Innovation Model by Carayannis and Campbell. The epistemic perspective considers the understanding of generative AI (GenAI) as a sixth helix of knowledge ...

Multi‐Sequence Fusion MRI Deep Learning Models for Discrimination of Recurrent Nasopharyngeal Carcinoma and Osteoradionecrosis

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objectives To develop a multi‐sequence fusion model based on MRI images to differentiate between recurrent nasopharyngeal carcinoma (rNPC) and osteoradionecrosis (ORN) in patients with nasopharyngeal carcinoma (NPC) after radiotherapy, and to evaluate its diagnostic performance.

use of modified quintuple helix innovation model

open access: yes, 2020
Life Cycle Assessment (LCA) is identified as a systematic analytical tool used to assess the total environmental burdens related to any product, process, or activity by assessing all upstream flows and all downstream flows throughout the whole value ...

Determination of the interaction impedance of helix slow-wave structures. [PDF]

open access: yes, 2000
The computer simulation of helix travelling-wave tubes requires accurate information about the phase velocity, interaction impedance and attenuation of the helix slow wave structure at each frequency.

Comparative Analysis of Stress Adaptation in the Yeast Microbiome of Cactus

open access: yesYeast, EarlyView.
Yeasts and related fungi isolated from cacti or nearby non‐cactus plants were characterized phenotypically and genomically, revealing differences that hint at modes of adaptation to the cactus host. ABSTRACT Together with other fungi, yeasts make up a significant component of the plant microbiome. As the planet warms, cacti expand their range.
