Bioprinted Organoids: An Innovative Engine in Biomedicine

open access: yesAdvanced Science, EarlyView.
Bioprinted organoids refer to either the printing of stem cells into tissue shape and subsequent differentiate into organoids, or assembling induced organoids as bioinks to replicate native organ. It enables the creation of miniaturized organs with complex architectures and physiological functions, potentially enhancing reproducibility, throughput, and

Theoretical analysis for critical fluctuations of relaxation trajectory near a saddle-node bifurcation

open access: yes, 2010
A Langevin equation whose deterministic part undergoes a saddle-node bifurcation is investigated theoretically. It is found that statistical properties of relaxation trajectories in this system exhibit divergent behaviors near a saddle-node bifurcation ...

Programmable and Reversible 3D‐to‐3D Shape Transformation: Hierarchical Multimodal Morphing Based on Liquid Crystal Elastomers

open access: yesAdvanced Science, EarlyView.
Hierarchical multimodal 3D‐to‐3D shape morphing is achieved in liquid crystal elastomer‐elastomer bilayers via programmable mismatch strains. Combining pre‐stretch and thermal actuation enables reversible transformations with non‐zero Gaussian curvature, empowering over 30 complex configurations for biomimetic camouflage, adaptive robotics, and dynamic

Efficient approaches for escaping higher order saddle points in non-convex optimization [PDF]

open access: yes, 2016
Local search heuristics for non-convex optimizations are popular in applied machine learning. However, in general it is hard to guarantee that such algorithms even converge to a local minimum, due to the existence of complicated saddle point structures ...

Diffusion Characteristics of Ru and Oxygen Vacancies in Ta2O5 for Resistive Random Access Memory Devices: A Density Functional Theory Investigation

open access: yesAdvanced Electronic Materials, EarlyView.
Atomistic analysis of ruthenium (Ru) and oxygen vacancy (OV) diffusion in Ta₂O₅‐based memristors is performed. DFT calculations demonstrate interstitial Ru in Ta₂O₅ has lower diffusion barriers and formation energies than OVs, enhancing mobility and stability.

Insights on SEI Growth and Properties in Na‐Ion Batteries via Physically Driven Kinetic Monte Carlo Model

open access: yesAdvanced Energy Materials, EarlyView.
The novel kinetic Monte Carlo model presented here incorporates spatially‐ and time‐dependent electrical potential, which enables the precise study of the solid electrolyte interphase formation in Na‐ion batteries. The effects of electrolyte composition and charging conditions on the growth and behavior of the solid electrolyte interphase during the ...
