Low-frequency scattering on a half-space filled with periodic fluid-solid medium with dipped layers

open access: yesГеофизический журнал, 2017
A low-frequency effective model has been developed for a medium with periodical liquid and solid layers with the slip between layers. It is shown that for an effective periodically n-layered medium with solid dipped layers with slip there exist n+1 ...

Passage of electromagnetic wave through a rectangular wave guide with an active rectangular film

open access: yesФизика волновых процессов и радиотехнические системы, 2020
The proposed work examines the passage of the electromagnetic wave through a rectangular wave guide with active film and magnetized ferritic layers. Ferrimagnetic layers are located between metal planes with perfect conductivity. Adispersion equation has

Shallow Water Waves and Conservation Laws with Dispersion Triplet

open access: yesApplied Sciences, 2022
This paper secures solitary waves and conservation laws to the familiar Korteweg–de Vries equation and Gardner’s equation with three dispersion sources. The traveling wave hypothesis leads to the emergence of such waves.

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.

Propagation of SH waves in a regular non-homogeneous monoclinic crustal layer lying over a non-homogeneous semi-infinite medium

open access: yesJournal of the Mechanical Behavior of Materials, 2016
This study discusses the dispersion equation for SH waves in a non-homogeneous monoclinic layer over a semi-infinite isotropic medium. The wave velocity equation has been obtained. In the isotropic case, when the non-homogeneity is absent, the dispersion

Bone Mineral Density After Contemporary Treatment for Acute Lymphoblastic Leukaemia: A Matched Cross‐Sectional Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Reduced bone mineral density (BMD) has been reported in survivors of childhood and young adult acute lymphoblastic leukaemia (ALL); however, data from cohorts treated with contemporary protocols and including matched controls remain limited.

Shear wave propagation in piezoelectric-piezoelectric composite layered structure

open access: yesLatin American Journal of Solids and Structures
The propagation behavior of shear wave in piezoelectric composite structure is investigated by two layer model presented in this approach. The composite structure comprises of piezoelectric layers of two different materials bonded alternatively ...
