Современная математика: Фундаментальные направленияWe consider strongly elliptic differential-difference equations with mixed boundary conditions in a bounded domain. There are homogeneous Dirichlet conditions on a part of the boundary, and boundary conditions of the third kind on the other part of the ...

On a fractional q-differential inclusion on a time scale via endpoints and numerical calculations
Advances in Difference Equations, 2020 By using an endpoint result for set-valued maps, we study the existence of solutions for a fractional q-differential inclusion with sum and integral boundary value conditions on the time scale T t 0 = { t 0 q , t 0 q 2 , … } ∪ { 0 } $\mathbb{T}_{t_{0}}= \

Boundary conditions in supergravity on a manifold with boundary [PDF]
Journal of High Energy Physics, 2006 We explain why it is necessary to use boundary conditions in the proof of supersymmetry of a supergravity action on a manifold with boundary. Working in both boundary (``downstairs'') and orbifold (``upstairs'') pictures, we present a bulk-plus-boundary/brane action for the five-dimensional (on-shell) supergravity which is supersymmetric with the use ...

A comparison of impedance boundary conditions for flow acoustics [PDF]
, 2013 Acoustic liners remain a key technology for reducing community noise from aircraft engines. The choice of optimal impedance relies heavily on the modeling of sound absorption by liners under grazing flows.

Control of lateral boundary conditions in four-dimensional variational data assimilation for a limited area model [PDF]
Tellus: Series A, Dynamic Meteorology and Oceanography, 2012 The limited area model forecasting problem is a lateral boundary condition (LBC) problem in addition to the initial condition problem. The data assimilation has traditionally been considered as a process for estimation of the initial condition only ...

Perturbations of periodic boundary conditions [PDF]
SIAM Journal on Mathematical Analysis, 1982 We consider perturbations of the problem (*) \(-x''+bx=\lambda ax,x(0)- x(1)=0, x'(0)-x'(1)=0\) both by changes of the boundary conditions and by addition of nonlinear terms. We assume that at \(\lambda =\lambda_ 0\) there are two linearly independent solutions of (*) and that a is bounded away from zero. When only the boundary conditions are perturbed

"Missing" boundary conditions? Discretize first, substitute next, and combine later [PDF]
, 1990 A simple approach exists to prevent the need for constructing boundary conditions in situations where they are not explicitly supplied by the original analytical formulation of the problem.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.
