A novel molecular dynamics approach to simulate micromechanical behavior in characteristic crystallographic planes of transparent alumina ceramics

Journal of Materials Research and Technology
To investigate the anisotropic properties of brittle-prone transparent alumina ceramics (TACs) and guide the optimized design of material modification, this study employed a novel molecular dynamics (MD) approach to reproduce and analyze the anisotropic ...

Biotic carbon feedbacks in a materially-closed soil-vegetation-atmosphere system [PDF]

, 2012
The magnitude and direction of the coupled feedbacks between the biotic and abiotic components of the terrestrial carbon cycle is a major source of uncertainty in coupled climate–carbon-cycle models1, 2, 3.

i‐Tac: Inverse Design of 3D‐Printed Tactile Elastomers with Tuneable Optical and Mechanical Properties

Advanced Intelligent Systems, EarlyView.
Inspired by the multi‐tissue architecture of the human fingertip dermis (A), this work introduces a mixture design using three PolyJet materials (AC/TM/GM) to expand the achievable elastomer property space (B). An inverse design pipeline (i‐Tac) is developed to map target optical/mechanical requirements to optimal material compositions (C), enabling ...

Exploring the classical and numerical Delboeuf illusion: the impact of transcranial alternating current stimulation on magnitude processing [PDF]

PeerJ
Understanding cognitive and neural mechanisms underlying quantity processing is crucial for unraveling human cognition. The existence of a single magnitude system, encompassing non-symbolic number estimation alongside other magnitudes like time and space,

Lasting effects of transcranial alternating current stimulation (tACS): which mechanisms?

Brain Stimulation
The growing use of non-invasive brain stimulation techniques in general, and of transcranial direct / alternating current stimulation (tDCS / tACS) in particular, has led to identifying physiological effects that outlast the cessation of stimulation (i.e. lasting effects).

Porcine kidney xenotransplantation: From primate models to clinical reality

Animal Models and Experimental Medicine, EarlyView.
In the face of a critical shortage of human donor kidneys for end‐stage renal disease patients, porcine kidney xenotransplantation has emerged as a viable solution. This field has navigated major hurdles, including immune rejection, physiological incompatibilities, potential biomechanical differences and the risk of cross‐species infection. To overcome

Human Sensation of Transcranial Electric Stimulation. [PDF]

, 2019
Noninvasive transcranial electric stimulation is increasingly being used as an advantageous therapy alternative that may activate deep tissues while avoiding drug side-effects. However, not only is there limited evidence for activation of deep tissues by

Energy‐Efficient and Sustainable Design Optimization for Ternary Mixture Separation: A Comparative Analysis of Sequential Iterative Optimization and Non‐Dominated Sorting Genetic Algorithm II

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study presents a comparative analysis of two optimization approaches: Sequential Iterative Optimization (SIO) and Non‐dominated Sorting Genetic Algorithm II (NSGA‐II) applied to the separation of ternary mixtures (1‐butanol, isobutanol, and 2‐butanol) using Dual‐Column Distillation (DCD) and Dividing‐Wall Column (DWC) processes. Through a

Integration bile acid metabolomics and gut microbiome to study the anti-liver fibrosis effects of total alkaloids of Corydalis saxicola Bunting

Chinese Medicine
Background Bile acids and gut microbiota participate in the pathogenesis of liver fibrosis (LF). The total alkaloids of Corydalis saxicola Bunting (TACS) is a traditional Chinese medicine extract that has been used to treat LF, but the underlying ...
