Computer Vision to the Rescue: Infant Postural Symmetry Estimation from Incongruent Annotations [PDF]

open access: yesarXiv, 2022
Bilateral postural symmetry plays a key role as a potential risk marker for autism spectrum disorder (ASD) and as a symptom of congenital muscular torticollis (CMT) in infants, but current methods of assessing symmetry require laborious clinical expert assessments.

Single Pair of Weyl Points Evolve From Spin Group‐Protected Nodal Line in Half‐Metallic Ferromagnet V3S4

open access: yesAdvanced Functional Materials, EarlyView.
A spin group (SG)‐based mechanism is proposed to realize a single pair of Weyl points. PT‐symmetric nodal lines (NLs) persist under T‐breaking, protected by the combination of SG and P symmetry. When considering spin‐orbit coupling, the SG‐protected NL will split into Weyl points, which will also induce anomalous transport phenomena arising from ...

“Therapies Through Gut:” Targeted Drug Delivery for Non‐Gastrointestinal Diseases by Oral Administration

open access: yesAdvanced Healthcare Materials, EarlyView.
Schematic illustration of the mechanism of targeted delivery of nanoparticles including 1) paracellular, 2) endolysosomal escape, 3) receptor mediated endocytosis, and 4) M cell mediated transport for non‐GI diseases by oral administration such as atherosclerosis, cancer, diabetes, and brain diseases. Abstract Oral drug delivery is a promising approach

Engineered Chitosan‐Derived Nanocarrier for Efficient siRNA Delivery to Peripheral and Central Neurons

open access: yesAdvanced Healthcare Materials, EarlyView.
This study introduces a novel chitosan‐based nanocarrier functionalized with a neurotropic protein for efficient siRNA delivery to neurons. The polyplexes demonstrate enhanced neuronal binding, retrograde transport, and PTEN silencing, promoting axonal outgrowth.

Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose

open access: yesAdvanced Materials, EarlyView.
Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...

A model of infant speech perception and learning [PDF]

open access: yesarXiv, 2016
Infant speech perception and learning is modeled using Echo State Network classification and Reinforcement Learning. Ambient speech for the modeled infant learner is created using the speech synthesizer Vocaltractlab. An auditory system is trained to recognize vowel sounds from a series of speakers of different anatomies in Vocaltractlab. Having formed

Polyphenol‐Derived Carbonaceous Frameworks with Multiscale Porosity for High‐Power Electrochemical Applications

open access: yesAdvanced Materials, EarlyView.
This review examines the fluid dynamic behavior within carbonaceous porous structures, linking structural characteristics to electrolyte transport and electrochemical performance. Specifically, it quantitatively assesses the effect of polyphenol derivatives‐harnessed multiscale pore structures on active surface utilization and electrochemical activity ...

Log-Contrast Regression with Functional Compositional Predictors: Linking Preterm Infant's Gut Microbiome Trajectories to Neurobehavioral Outcome [PDF]

open access: yesarXiv, 2018
The neonatal intensive care unit (NICU) experience is known to be one of the most crucial factors that drive preterm infant's neurodevelopmental and health outcomes. It is hypothesized that stressful early life experience of very preterm neonate is imprinting gut microbiome by the regulation of the so-called brain-gut axis, and consequently, certain ...
