Embedded Ferroelectric Nanoclusters Can Drive Polarization Reversal in a Non‐Ferroelectric Polar Film via the Proximity Effect

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectric nanoclusters create local internal fields in a normally non‐switchable polar film because of polarization mismatch at their interfaces. That field opposes polarization in the regions with larger polarization and reinforces polarization in the regions with smaller polarization.

Monolithic Oxidation Enables Ultrathin Vertically Graded Tantalum Oxide for Low‐Voltage, Low‐Variability Memristive Switching

open access: yesAdvanced Functional Materials, EarlyView.
Monolithic UV‐ozone oxidation of Ta forms an ultrathin Ta2O5/TaOx bilayer enabling resistive switching with a vertical defect gradient. A stoichiometric surface layer over an oxygen‐deficient sublayer promotes localized filament nucleation near the top interface, enabling low‐voltage operation, and reduced cycle‐to‐cycle variability.

On sum of monotone operator of type (FPV) and a maximal monotone operator

open access: yesNew Trends in Mathematical Science, 2016
In the setting of a general real Banach space, we prove that the sum of a monotone operator A of type (FPV) and a maximal monotone operator B is maximal with domA∩ int domB6 φ and either domB is open or for any x ∈ domA∩ int domB, kx ∗ k ≤ |B(x)|, x ∗ ∈ A(x).

To the theory of operator monotone and operator convex functions

open access: yes, 2020
We prove that a real function is operator monotone (operator convex) if the corresponding monotonicity (convexity) inequalities are valid for some normal state on the algebra of all bounded operators in an infinite-dimensional Hilbert space.

Characterizations of Positive Operator-Monotone Functions and Monotone Riemannian Metrics via Borel Measures

open access: yes, 2019
We show that there is a one-to-one correspondence between positive operator-monotone functions on the positive reals, monotone Riemannian metrics, and finite positive Borel measures on the unit interval.

Semiconducting Polymers Post‐Functionalized With Ureido‐Pyrimidinone for Robust Stretchable Transistors

open access: yesAdvanced Functional Materials, EarlyView.
The design of intrinsically robust stretchable semiconducting polymers was achieved through OTBS‐mediated post‐functionalization of PDPP2T side chains with UPy units, generating dual hydrogen‐bonding motifs comprising weaker urethane linkages and strong quadruple UPy interactions along the long alkyl side chain, which is crucial for achieving desirable

A Hybrid Iterative Scheme for a Maximal Monotone Operator and Two Countable Families of Relatively Quasi-Nonexpansive Mappings for Generalized Mixed Equilibrium and Variational Inequality Problems

open access: yesAbstract and Applied Analysis, 2010
We introduce a new hybrid iterative scheme for finding a common element of the set of common fixed points of two countable families of relatively quasi-nonexpansive mappings, the set of the variational inequality for an α-inverse-strongly monotone ...

Convergence theorems for split feasibility problems on a finite sum of monotone operators and a family of nonexpansive mappings

open access: yesJournal of Inequalities and Applications, 2018
In this paper, we present two iterative algorithms for approximating a solution of the split feasibility problem on zeros of a sum of monotone operators and fixed points of a finite family of nonexpansive mappings.

A note on quasi‐monotone operators

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1987
The treatment of nonlinear problems using a general framework is often a delicate issue. This is illustrated by the fact that the quasi‐monotone operators of M. A. Noor are constant operators.
