Structure Design and Magnetic Field Simulation of Non-contact Nutation Reduction Motor

Jixie chuandong, 2019
In order to solve the problem of weak stiffness of flexible wheels and more mechanical friction in existing robot harmonic reducer motors, a new type of nutation reducer motor is proposed by combining nutation deceleration motion with magnetic meshing ...

The Electronic Spin State of Diradicals Obtained from the Nuclear Perspective: The Strange Case of Chichibabin Radicals. [PDF]

Chemphyschem
The electronic spin state of two Chichibabin radicals is investigated using 2‐dimensional hyperfine correlated Electron Nuclear Double Resonance. The protons (I=1/2) act as a reference for the electronic spin quantum number (S) via their hyperfine interactions.

Novel Monoclonal Antibody Detects Small Aβ Oligomers More Sensitively Than Lecanemab in Alzheimer's Disease CSF, Serum and Culture Media

Annals of Neurology, EarlyView.
Objective Aqueously diffusible oligomers of the amyloid β‐protein (oAβ) are neurotoxic and play a role in neuronal dysfunction in Alzheimer's disease (AD). Accurate quantification of oAβ in brains and biofluids could be valuable for understanding and monitoring AD.

Multimaterial Triphasic Scaffold Replicates Enthesis Microenvironment to Modulate Early Cell Responses

Advanced NanoBiomed Research, EarlyView.
A bioinspired triphasic scaffold integrating 3D printed polycaprolactone and electrospun poly(lactic‐co‐glycolic acid) is developed to replicate the organization of the tendon‐to‐bone enthesis. Cyclic mechanical stimulation induces spatially defined cell morphology and lineage‐related gene expression in human mesenchymal stem cells, highlighting the ...

Observation model and parameter partials for the JPL VLBI parameter estimation software MASTERFIT-1987 [PDF]

This report is a revision of the document of the same title (1986), dated August 1, which it supersedes. Model changes during 1986 and 1987 included corrections for antenna feed rotation, refraction in modelling antenna axis offsets, and an option to ...

Harnessing the Interfacial Activity of Soluble Faba Protein‐Tannic Acid Conjugates for Enhanced Lipid Oxidative Stability of Oil‐in‐Water Emulsions

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT In oil‐in‐water emulsions, lipid oxidation begins at the interface between the two phases. One strategy to slow down this process is to place antioxidants at the interface, where they can directly block oxidative reactions. This study explored that idea by conjugating soluble faba bean protein with tannic acid using the free‐radical grafting ...

Nonlinear response of magnetization obeying inertial dynamics to superimposed dc and ac fields and dynamic magnetic hysteresis

AIP Advances
The nonlinear ac stationary responses of magnetization and the dynamic magnetic hysteresis of ferromagnetic particles with uniaxial anisotropy acted on by both external dc and ac magnetic fields are evaluated by employing the inertial Landau–Lifshitz ...

Compositional Characterization, Quality Parameters, and Physicochemical and Bioactive Properties of Pequi (Caryocar brasiliense) Oils From Xingu and Cerrado in Mato Grosso, Brazil

Journal of the American Oil Chemists' Society, EarlyView.
Cerrado oil is richer in MUFA and antioxidant compounds, while Xingu oil shows higher SFA and enhanced oxidative stability, reinforcing the potential of pequi oil as a sustainable bioactive ingredient. ABSTRACT Pequi (Caryocar brasiliense) is a native fruit widely distributed in Brazilian biomes, specially in Cerrado, known for its high oil yield and ...

Optimization design of radial meshing nutation magnetic gear system based on D-APSO algorithm

Advances in Mechanical Engineering
To combine the high transmission ratio of nutation drives with the non-contact power transfer of permanent-magnet gears, this paper proposes a novel radial meshing nutation magnetic drive system (RMNMD) and investigates its magnetic coupling mechanism ...

Finite element analysis of feeding in red and gray squirrels (Sciurus vulgaris and Sciurus carolinensis)

The Anatomical Record, EarlyView.
Abstract Invasive gray squirrels (Sciurus carolinensis) have replaced the native red squirrel (Sciurus vulgaris) across much of Great Britain over the last century. Several factors have been proposed to underlie this replacement, but here we investigated the potential for dietary competition in which gray squirrels have better feeding performance than ...
