Universal Conductance Fluctuations in Quantum Anomalous Hall Insulators

open access: yesAdvanced Materials, EarlyView.
Universal conductance fluctuations are observed in mesoscopic quantum anomalous Hall insulators. Two distinct fluctuation patterns are identified, arising from different interference processes of bulk and chiral edge states, respectively. These findings unveil rich quantum interference phenomena in quantum anomalous Hall insulators and provide insights

Dynamic Optical Lattices Through Conducting Polymer‐Gated Confinement

open access: yesAdvanced Materials, EarlyView.
The conducting polymer gate is incorporated into organic dielectric lattices to control the dynamic switching of nonlocal Mie resonances in the visible/NIR regions. The “closed gate” from oxidized PEDOT confines the light within dielectric nanocylinders and activates nonlocal Mie resonances, while the “opened gate” from reduced PEDOT facilitates ...

On the Complexity of Optimization over the Standard Simplex [PDF]

open access: yes
We review complexity results for minimizing polynomials over the standard simplex and unit hypercube.In addition, we show that there exists a polynomial time approximation scheme (PTAS) for minimizing Lipschitz continuous functions and functions with ...

Influence of Micropillar Height Modulation on Droplet Evaporation and Wetting State Transitions

open access: yesAdvanced Materials Interfaces, EarlyView.
Controlling droplet evaporation dynamics is crucial across many fields. Here, it demonstrates laser‐fabricated polymer micropillar arrays with tailored height variations to regulate evaporation behavior. While all arrays exhibit superhydrophobic wetting, their distinct height profiles effectively slow evaporation and alter evaporation modes ...

Approximation of Signals (Functions) by Trigonometric Polynomials in Lp-Norm

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2014
Mittal and Rhoades (1999, 2000) and Mittal et al. (2011) have initiated a study of error estimates En(f) through trigonometric-Fourier approximation (tfa) for the situations in which the summability matrix T does not have monotone rows.

A Sleeve Alters the Pressure‐Stretch Curve of a Hyperelastic Balloon to Enable Pre‐Programmed Sequencing

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This article demonstrates that encasing a hyperelastic balloon in an inextensible sleeve greatly increases its burst pressure. This simple mechanical behavior can be used to produce an asymmetric inflation‐deflation sequence for coupled balloons with different thicknesses so they could serve as a soft robot's rear and front anchors when driven from a ...

Finding exact minimal polynomial by approximations

open access: yesProceedings of the 2009 conference on Symbolic numeric computation, 2009
We present a new algorithm for reconstructing an exact algebraic number from its approximate value using an improved parameterized integer relation construction method. Our result is consistent with the existence of error controlling on obtaining an exact rational number from its approximation.

Printed 2.5D‐Microstructures with Material‐Specific Functionalization for Tunable Biosensing

open access: yesAdvanced Materials Technologies, EarlyView.
The 2.5D‐MiSENSE platform integrates a microstructured biosensor with an in‐line milking pipeline to enable real‐time detection of mastitis biomarkers during active milk flow. The system uses a 2.5D microengineered surface and patterned electrodes to enhance milk–sensor interaction.
