We implement a computational algorithm to study the pattern formation and transition of slime mould. Inspired by shape-shifting feature in growth of slime mould the nutrient-induced, we then translate the learned principles into the design and characterization of cellular materials, with particular focus on the issue of spatial heterogeneity due to the nature of the non-uniform, asymmetric pattern. Guided by clustering analysis, compression tests on 3D-printed samples, and numerical simulations by finite element models, we were able to categorize patterns with certain geometric features (such as layout and symmetry) and found similar mechanical response features, indicating high tailorability of non-uniform architected materials. This study paves the road for the advanced computer-aided design of architected materials and its potential in the development of innovative engineering mechanical devices and structural systems.

Response evaluation criteria in solid tumours (RECIST) is widely used to assess tumour response but is limited by not considering disease site or radiological heterogeneity (RH).
Purpose of this study was to evaluate the association of the spatial heterogeneity (asphericity, ASP) in intra-therapeutic SPECT/ CT imaging of somatostatin receptor (SSR) positive metastatic gastroen...
This study is designed to see if doing regular training on a spatial imagery task leads to improvements in the ability to do the trained spatial imagery task and in the ability to get arou...
Building on previous work of the Myotonic Dystrophy Clinical Research Network (DMCRN), the present study seeks to overcome insufficient data on natural history; lack of reliable biomarkers...
This study is designed to develop and test the use of Interactive Voice Response (IVR) technology to deliver pain management treatment. IVR allows individuals to receive and provide inform...
Cardiovascular disease (CVD) is the leading cause of death worldwide. Most individuals with CVD show no evidence of disease for decades as the disease progresses before the first onset of ...
The purpose of this study is to determine whether intensive slackline training improves spatial orientation abilities, balancing skills and causes neuroplasticity in related brain cortical...
Methods used to take into account and incorporate spatial autocorrelation and regional variation into regression analysis models of data that has spatial dependency, and also to provide information on the spatial relationships among the variables.
Works consisting of bibliographic records, created according to specific and uniform principles of construction and under the control of an authority file, which describe the materials contained in a collection, library, or group of libraries. Catalogs include also lists of materials prepared for a particular purpose, such as exhibition catalogs, sales catalogs, garden catalogs, medical supply catalogs.
