Length of a curve is quasi-convex along a Teichmuller geodesic

open access: yes, 2010
We show that for every simple closed curve \alpha, the extremal length and the hyperbolic length of \alpha are quasi-convex functions along any Teichmuller geodesic.

Flexible Polypyrrole‐Based pH Sensors via Oxidative Chemical Vapor Deposition

open access: yesAdvanced Healthcare Materials, EarlyView.
Oxidative chemical vapor deposition (oCVD) of polypyrrole (PPy) thin films yields flexible, electrically conductive, and biocompatible pH sensors for monitoring on‐skin biological events. The highly sensitive, oCVD PPy skin‐conformal sensors enable real‐time, spatially resolved sensing of dynamic pH changes within physiologically relevant ranges (4–9 ...

Unveiling the Role of Curvature in Carbon for Improved Energy Release of Ammonium Perchlorate

open access: yesAdvanced Materials, EarlyView.
High‐curvature carbon materials identified via machine learning and simulation can enhance the heat release and combustion performance of ammonium perchlorate. ABSTRACT The catalytic role of carbon curvature in the thermal decomposition of ammonium perchlorate (AP) remains largely unexplored. To address this gap, this study employs machine learning and

On ω-Interpolative Berinde Weak Contraction in Quasi-Partial b-Metric Space

open access: yesInternational Journal of Analysis and Applications, 2021
The aim of this paper is to introduce interpolative weak contraction in the notion of Berinde weak operator in quasi-partial b-metric space and to extend and generalize fixed point results by adopting the condition of ω-admissibility.

Remorphable Architectures: Reprogramming Global Bistability through Locally Bistable Metamaterials

open access: yesAdvanced Materials, EarlyView.
Local bistable reconfiguration in mechanical metamaterials is leveraged in globally bistable architectures to enable in situ reprogrammable transition pathways through state flip of individual building blocks. The local‐to‐global correspondence of instabilities empowers soft robotic systems with on‐demand morphing traits, as well as aerospace ...

BERGMANN AND HARDY SPACES AND CONJUGATE OF THEM

open access: yesAdvanced Engineering Research, 2012
It is proved that  space is strongly notmed, and  is neither strongly notmed, nor uniformly convex. A standard form of the linear functionals over  space and over metric spaces of  0 < p £ 1, is determined.

Enriched rational type contractions in quasi-Banach spaces and generalized convex b-metric spaces

open access: yesApplied General Topology
In this paper, we define enriched rational type contraction in the setting of quasi-Banach spaces and prove the existence and uniqueness of fixed point of the enriched contraction by using Krasnselskii iteration procedure.

Excited State Opto‐Ionic Reservoir Computing in Hybrid Perovskite Electrochemically‐Gated Luminescent Cells

open access: yesAdvanced Materials, EarlyView.
A neuromorphic computing system exploiting opto‐ionic modulation in lead halide perovskite microcrystals demonstrates high‐dimensional reservoir dynamics with diffraction‐limited node resolution. Leveraging ultrafast excited‐state interactions, it achieves efficient computation (800 pJ/node‐operation), robustly distinguishing 4‐bit pulse sequences ...
