Explicit criteria for the oscillation of second-order differential equations with several sub-linear neutral coefficients

Advances in Difference Equations, 2020
In this work, we present sufficient conditions for oscillation of all solutions of a second-order functional differential equation. We consider two special cases when γ > β $\gamma >\beta $ and γ < β $\gamma

A Systematic Study of GelMA‐Carbopol Bioinks for High‐Fidelity Extrusion 3D Bioprinting at Physiological Temperatures

Advanced Healthcare Materials, EarlyView.
Gonzalez Martinez and collaborators develop a strategy to formulate high performance GelMA‐based bioinks with low solids contents. The resulting bioinks enable 3D bioprinting at 37 °C of high‐fidelity structures with tunable mechanical properties that support high cell viability and function.

Beta oscillation is an indicator for two patterns of sensorimotor synchronization

PsyCh Journal, 2023
AbstractPrevious study indicates that there are two distinct behavioral patterns in the sensory‐motor synchronization task with short stimulus onset asynchrony (SOA; 2–3 s) or long SOA (beyond 4 s). However, the underlying neural indicators and mechanisms have not been elucidated.

An Intrinsic Role of Beta Oscillations in Memory for Time Estimation [PDF]

Scientific Reports, 2018
Abstract The neural mechanisms underlying time perception are of vital importance to a comprehensive understanding of behavior and cognition. Recent work has suggested a supramodal role for beta oscillations in measuring temporal intervals. However, the precise function of beta oscillations and whether their manipulation alters timing

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Gapless Superconductivity From Extremely Dilute Magnetic Disorder in 2H‐NbSe2‐xSx

Advanced Materials, EarlyView.
We demonstrate that 2H‐NbSe2‐xSx hosts gapless superconductivity at unexpectedly low magnetic impurity concentrations. Combining STM, Bogoliubovde Gennes simulations, DFT, and quasiparticle interference, we comprehensively study the development of gapless behavior and show that SeS substitution reshapes the band structure, enhances nesting, and drives ...
