Electronic Journal of Qualitative Theory of Differential Equations, 2016 We study the half-linear neutral differential equation \begin{equation*} \Bigl[r(t)\Phi(z'(t))\Bigr]'+c(t)\Phi(x(\sigma(t)))=0, \qquad z(t)=x(t)+b(t)x(\tau(t)), \end{equation*} where $\Phi(t)=|t|^{p-2}t$.

Structural Porosity and Low Mineral Density in Enamel Rods Drive Molar Incisor Hypomineralisation
Advanced Functional Materials, EarlyView.This study uses advanced imaging modalities on multiple length scales to show that molar‐incisor hypomineralization does not present as a locally homogeneous pathology. Instead, microstructural defects, characterized through non‐mineralized, protein‐rich sheaths and an altered mineral structure in between prism rods, resulting in local differences in ...

Oscillation Criteria for Odd Order Neutral Equations
Journal of Mathematical Analysis and Applications, 1994 Some results are obtained for oscillation of all solutions of the odd order neutral differential equation \[ (x(t)- px(t- \tau))^{(n)}+ \sum^ m_{i= 1} p_ i(t) f_ i(x(t- \sigma_ i))= 0,\tag{1} \] where \(p_ i(t)\geq 0\), \(\sigma_ i\in (0, \infty)\), \(f_ i: \mathbb{R}\to \mathbb{R}\) \((i= 1,2,\dots, m)\), \(p, \tau\in [0, \infty)\).

Advanced Functional Materials, EarlyView.MagPiezo enables wireless activation of endogenous Piezo1 channels without genetic modification using 19 nm magnetic nanoparticles and low‐intensity magnetic fields. It generates torque forces at the piconewton scale to trigger mechanotransduction in endothelial cells, standing as a novel platform to interrogate and manipulate Piezo1 activity in vitro.

Electroweak stability and non-minimal coupling
, 2017 The measured values of the Higgs and top quark mass indicate that the electroweak vacuum is metastable if there is no new physics below the Planck scale. This is at odds with a period of high scale inflation.

Stability criteria for negative-resistance oscillators
Electronics Letters, 1975 The stability criterion for a free-running negative-resistance oscillator is shown to be invariant to transformation through a wide class of 2-port networks connecting the device terminals to a convenient reference plane in the external circuit. In this way, the experimental application of the criterion to a given circuit is greatly simplified.

Mechanically Stable and Tunable Photoactivated Peptide‐Based Hydrogels for Soft Tissue Adhesion
Advanced Functional Materials, EarlyView.A collagen‐like peptide hydrogel platform is developed using supramolecular self‐assembly and light‐triggered crosslinking. It creates mechanically stable, tunable hydrogels with cytocompatibility and biodegradability, making them potential soft tissue adhesives.
