Chiari I Malformation: Review and Update of Current Treatment Options

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The pathophysiology of Chiari malformation type I (CM‐I) is complex, involving structural abnormalities at the craniovertebral junction that result in herniation of the cerebellar tonsils through the foramen magnum. In this study, we aim to present and evaluate current treatment options for CM‐I, with a focus on evidence‐based clinical ...

Multi species turing patterns in three dimensions

open access: yes, 2023
In 1952, Alan M. Turing presented a reaction-diffusion model that described formation of skin patterns. The patterns he predicted have later been found in various natural phenomena, such as in skins of fish or even in vegetation around termite hills. His

Dynamic‐FLPs Enabled by Orbital Hybridization Tuning: Boosting 100% CO Selectivity for Dilute CO2‐to‐CO Conversion

open access: yesCarbon Energy, EarlyView.
This study, for the first time, constructs photostructured dynamic frustrated Lewis pairs (DFLPs) via a p‐p orbital hybridization regulation strategy, achieving the 100% reduction of low‐concentration CO₂ to CO and breaking the stability‐activity trade‐off.

Neimark-Sacker-Turing Instability and Pattern Formation in a Spatiotemporal Discrete Predator-Prey System with Allee Effect

open access: yesDiscrete Dynamics in Nature and Society, 2018
A spatiotemporal discrete predator-prey system with Allee effect is investigated to learn its Neimark-Sacker-Turing instability and pattern formation.

Turing Patterning Using Gene Circuits with Gas-Induced Degradation of Quorum Sensing Molecules. [PDF]

open access: yesPLoS ONE, 2016
The Turing instability was proposed more than six decades ago as a mechanism leading to spatial patterning, but it has yet to be exploited in a synthetic biology setting.

Mass Transport Mechanisms in 2D Laminar Nanofluidic Membranes for Separation and Energy Conversion

open access: yesCarbon Innovation, EarlyView.
This review explores how two‐dimensional laminar membranes govern the transport of ions and molecules in confinement for advanced separation and energy conversion. By discussing how nanochannel architecture shapes membrane performance, this work highlights cation intercalation and functional modifications to improve osmotic energy harvesting ...

Globally Stable Microresonator Turing Pattern Formation for Coherent High-Power THz Radiation On-Chip

open access: yesPhysical Review X, 2017
In nonlinear microresonators driven by continuous-wave (cw) lasers, Turing patterns have been studied in the formalism of the Lugiato-Lefever equation with emphasis on their high coherence and exceptional robustness against perturbations. Destabilization

Coupled Effects of Turing and Neimark-Sacker Bifurcations on Vegetation Pattern Self-Organization in a Discrete Vegetation-Sand Model

open access: yesEntropy, 2017
Wind-induced vegetation patterns were proposed a long time ago but only recently a dynamic vegetation-sand relationship has been established. In this research, we transformed the continuous vegetation-sand model into a discrete model.

Adversarial Turing Patterns from Cellular Automata

open access: yes, 2021
State-of-the-art deep classifiers are intriguingly vulnerable to universal adversarial perturbations: single disturbances of small magnitude that lead to misclassification of most inputs.

Safeguarding Online Research in Eating Disorders Against Fraud: Increasing Risks and Practical Recommendations

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Recent growth of online research has been accompanied by an increase in reports of fraudulent participants, which can significantly comprise research validity. Drawing from our experience using Qualtrics with open recruitment, existing literature, and emerging studies in eating disorders (ED), we outline the risk and provide simple ...
