Equivalent Substitution of Stress Balanced Tooth Profile based on Eccentricity Modification

open access: yesJixie chuandong, 2018
By the theory of equivalent substitution,the FT455 model with high precision FT pin-cycloid is used as the carrier,and based on the way of eccentricity modification,the equivalent substitution of stress balanced tooth profile is carried out.

Nonlinear vibration of the bevel gear with teeth profile modification

open access: yes, 2016
The prediction of gear vibration and noise has always been a major concern in gear design. Noise and vibration are inevitable problems that are involved in transmission systems; they have intensified when some nonlinear phenomena such as jump phenomenon,

Proteomic profiling of Elp1‐deficient trigeminal ganglia reveals disruption of neurotrophic and metabolic pathways in a familial dysautonomia mouse model

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Elp1, a subunit of the Elongator complex, is essential for tRNA modification and neuronal development. Mutations in ELP1 underlie familial dysautonomia (FD), a disorder marked by sensory and autonomic neuropathy. While loss of Elp1 disrupts trigeminal ganglion formation and survival, the downstream molecular consequences remain ...

Jaw‐specific stem cell dynamics are associated with distinct enamel architecture in mouse incisors

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The continuously growing mouse incisor serves as a model for stem cell‐driven tooth renewal. Although mice possess maxillary and mandibular incisors, most studies have focused on the mandible. Potential differences in structure and renewal between these serially homologous organs remain insufficiently characterized.

Orthodentine‐osteodentine and osteocytic‐anosteocytic transition inferred from Silurian stem chondrichthyan dermal jawbones with ever‐white teeth overgrown by brown denticles

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...

Research on evaluation of tooth profile modification effect of locomotive traction

open access: yes
At present, the evaluation of the tooth profile modification effect of locomotive traction gears is plagued by the drawbacks of a single evaluation index and a lack of systematic evaluation methods.

All‐in‐One Intelligent Hemostatic Sponge: Rapid Hemostasis for Non‐Compressive Wounds With Synergetic Enhanced Antibacterial Efficacy and Self‐Reporting Biodegradation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Clinicians often concurrently tackle critical challenges including emergency hemorrhage, secondary infection, and the elusive tracking of biodegradation of conventional hemostatic agents for complex wounds. Here, we report an intelligent hemostatic sponge (spCS@AIE) by incorporating aggregation‐induced emission (AIE) nanoparticles with short‐wave ...

Laser‐Textured Field‐Engineered Interface for Robust Dry‐Processed Cathodes in Lithium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Laser‐patterned dry electrodes applied to current collectors could serve as a promising alternative to the limitations of conventional dry electrodes. Laser technology provides a fast and simple method to enhance the surface roughness of current collectors, improving the adhesion at the electrode–current collector interface.
