The Longitudinal and Transverse Piezoelectric Effects of the Ferroelectric Polymer P(VDF‐TrFE)

open access: yesMacromolecular Materials and Engineering, EarlyView.
The ordered amorphous (OA) domains play a crucial role in shaping the polymer behavior, both in terms of its structure and its functional properties. After the first electric field application, even small nanostructural changes lead to measurable effects yielding the longitudinal and transverse piezoelectric coefficients.

From Darboux-Egorov system to bi-flat $F$-manifolds

open access: yes, 2012
Motivated by the theory of integrable PDEs of hydrodynamic type and by the generalization of Dubrovin's duality in the framework of $F$-manifolds due to Manin [22], we consider a special class of $F$-manifolds, called bi-flat $F$-manifolds. A bi-flat $F$-

Optimal performance design of bat algorithm: An adaptive multi‐stage structure

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
Abstract The bat algorithm (BA) is a metaheuristic algorithm for global optimisation that simulates the echolocation behaviour of bats with varying pulse rates of emission and loudness, which can be used to find the globally optimal solutions for various optimisation problems. Knowing the recent criticises of the originality of equations, the principle

Identifying family environment profiles in families of children with prenatal alcohol exposure

open access: yesAlcohol, Clinical and Experimental Research, EarlyView.
This study provides novel information about patterns in the family environment in children with prenatal alcohol exposure (PAE). Latent profile analysis identified four distinct patterns of family environments in children with PAE characterized by cohesion, conflict, and organization: (1) low cohesion, (2) low organization, (3) high cohesion and ...

Relation Between Brain Morphological Features and Psychiatric Hospitalization Risk in Major Depressive and Bipolar Disorders

open access: yesActa Psychiatrica Scandinavica, EarlyView.
ABSTRACT Introduction Patients with mood disorders, especially, major depressive disorder (MDD) and bipolar disorder (BD), are at heightened risk of relapse and psychiatric rehospitalizations. Therefore, there is an urgent need to identify modifiable biomarkers to inform personalized and intensified prevention strategies for those at the greatest risk ...
