Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry

open access: yesAdvanced Functional Materials, EarlyView.
In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...

Young people’s experiences of fashion modelling: An exploratory phenomenological study [PDF]

open access: yes, 2017
Research about fashion modelling within Psychology remains sparse. Rare empirical studies which do exist exhibit a tendency to pathologise models, and provide only a superficial insight into this career.

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies

open access: yesAdvanced Functional Materials, EarlyView.
The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

The benefits of diligence: how precise are predicted gravitational wave spectra in models with phase transitions?

open access: yesJournal of High Energy Physics, 2021
Models of particle physics that feature phase transitions typically provide predictions for stochastic gravitational wave signals at future detectors and such predictions are used to delineate portions of the model parameter space that can be constrained.

On Parameter Interpretability of Phenomenological-Based Semiphysical Models

open access: yes, 2018
Empirical and phenomenological based models are used to represent biological and physiological processes. Phenomenological models are derived from the knowledge of the mechanisms that underlie the behaviour of the system under study, while empirical ...

Atomized Oxidative Polymerization as a 3D Printing Platform for Binder‐Free, Bulk Conductive Polymer Architectures

open access: yesAdvanced Functional Materials, EarlyView.
Co‐delivery of electrosprayed EDOT and oxidant enables bulk oxidative polymerization during layer‐by‐layer fabrication, creating stable, highly conductive 3D PEDOT structures. This Atomized Oxidative Polymerization (AOP) overcomes the surface deposition‐only and matrix‐limited conductivity of conventional Vapor Phase Polymerization (VPP) and PEDOT:PSS ...

Serendipity in dark photon searches

open access: yesJournal of High Energy Physics, 2018
Searches for dark photons provide serendipitous discovery potential for other types of vector particles. We develop a framework for recasting dark photon searches to obtain constraints on more general theories, which includes a data-driven method for ...

Bayesian fit analysis to full distribution data of B ¯ → D ∗ ℓ ν ¯ : V cb $$ \overline{\mathrm{B}}\to {\mathrm{D}}^{\left(\ast \right)}\mathrm{\ell}\overline{\nu }:\left|{\mathrm{V}}_{\mathrm{cb}}\right| $$ determination and new physics constraints

open access: yesJournal of High Energy Physics, 2020
We investigate the semi-leptonic decays of B → D ∗ ℓ ν ¯ $$ B\to {D}^{\left(\ast \right)}\mathrm{\ell}\overline{\nu } $$ in terms of the Heavy-Quark-Effective-Theory (HQET) parameterization for the form factors, which is described with the heavy quark ...

Flavor SU(3) in Cabibbo-favored D-meson decays

open access: yesJournal of High Energy Physics, 2021
Model-independent description of nonleptonic decays of charmed mesons is a challenging task due to large nonperturbative effects of strong interactions on the transition amplitudes.
