What Makes A Business Ecosystem Circular? A Multilevel Review

Business Strategy and the Environment, EarlyView.
ABSTRACT Drawing on multilevel and complexity theories, this research identifies new and reframed core principles of circular business ecosystems (CBEs), thereby clarifying what makes a business ecosystem circular. Although CBEs are increasingly recognised as adaptive systems shaped by interdependencies and non‐linear interactions, how circularity ...

The fractal cosmological model

, 2011
The fractal cosmological model which accounts for observable fractal properties of the Universe's large-scale structure is constructed. In this framework these properties are consequences of the rotary symmetry of charged scalar meson matter field (complex field). They may be explained through a conception of the Universe as an assembly of self-similar

Durability Degradation and Fractal Strength Prediction of Bentonite-Slurry/Steel-Slag Foamed Concrete Under Corrosive Wetting–Drying Exposure

Buildings
Bentonite slurry (BS) and steel slag powder (SS) were co-utilized to develop bentonite-slurry/steel-slag foamed concrete (BS-SSFC). The evolution of compressive strength and the associated deterioration mechanisms were examined after repeated wetting ...

VERMONT μQFR: Diagnostic Accuracy of Murray Law‐Based 2D‐μQFR Compared to 3D‐μQFR and vFFR

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Murray law‐based quantitative flow ratio (μQFR) is an angiography‐derived physiological index that utilizes a single angiographic projection with artificial intelligence‐guided vessel segmentation. Aims To evaluate the diagnostic accuracy and time efficacy of 2D‐μQFR against wire‐based fractional flow reserve (FFR ≤ 0.80), compare ...

Fractal Based Procedural Modelling [PDF]

, 1994
Two different methods for procedurally based modelling are presented as an alternative to the interactive modelling. Fractal and graftal techniques are shown to be the possibilities for modelling of natural phenomena as terrain shapes and trees. Different issues of consistency for fractal based terrain modelling are discussed.

Modeling of Color and Degradation of C‐Phycocyanin Extracted From Arthrospira platensis and Chlorogloeopsis HTF

Chemie Ingenieur Technik, EarlyView.
A nonlinear kinetic model was developed and successfully implemented, which describes the degradation of the protein C‐phycocyanin depending on temperature and pH value. C‐phycocyanin had been extracted from two different cyanobacteria. In addition to protein degradation, the fading of the typical blue color of this protein was included in the model ...
