Exponential localization of odd, even, and multi-pulse discrete breathers in Fermi–Pasta–Ulam–Tsingou lattices

AIP Advances
Discrete breathers are spatially localized periodic solutions in nonlinear lattices. The existence of odd and even symmetric single-pulse and multi-pulse discrete breathers has been proved in the one-dimensional Fermi–Pasta–Ulam–Tsingou lattices with ...

Emergent Spin‐Glass Behavior in an Iron(II)‐Based Metal–Organic Framework Glass

Advanced Functional Materials, EarlyView.
A one‐pot, solvent‐free synthesis yields an Fe2+‐based metal‐organic framework (MOF) glass featuring a continuous random network structure. The material exhibits spin‐glass freezing at 14 K, driven by topological‐disorder and short‐range magnetic frustration, showcasing the potential of MOF glasses as a plattform for cooperative magnetic phenomena in ...

Dynamics of localized waves and interaction solutions for the ( 3 + 1 ) $(3+1)$ -dimensional B-type Kadomtsev–Petviashvili–Boussinesq equation

Advances in Difference Equations, 2020
In this work, we investigate the ( 3 + 1 ) $(3+1)$ -dimensional B-type Kadomtsev–Petviashvili–Boussinesq equation, which can be used to describe the processes of interaction of exponentially localized structures.

Selenium‐Incorporated Polymerized Nonfullerene Acceptors/SWCNT Composites with Polymer‐Assisted n‐Doping for High‐Performance Organic Thermoelectrics

Advanced Functional Materials, EarlyView.
Selenium‐incorporated polymerized nonfullerene acceptor PCB2Se forms a strong supramolecular complex with SWCNTs, enabling a record‐high zT of 0.29. Sequential N‐DMBI doping, mediated through a polymer‐assisted electron‐transfer pathway, successfully converts the PCB2Se/SWCNT composite into an efficient n‐type material with an impressive power factor ...

q-breathers in Discrete Nonlinear Schroedinger lattices

, 2008
$q$-breathers are exact time-periodic solutions of extended nonlinear systems continued from the normal modes of the corresponding linearized system. They are localized in the space of normal modes. The existence of these solutions in a weakly anharmonic

Discrete Breathers with Dissipation [PDF]

, 2008
The interplay between discreteness and nonlinearity leads to the emergence of a new class of nonlinear excitations, viz. discrete breathers. These time-periodic and spatially localized excitations correspond to generic exact solutions of the underlying nonlinear lattice models.

Dentofacial morphology of mouth breathing children

Brazilian Dental Journal, 2002
The relationship between dentofacial morphology and respiration has been debated and investigated from various approaches. The aim of this study was to verify the skeletal and dental relationship of mouth and nose breathing children. Thirty-five children,
