The existence and multiplicity of L 2-normalized solutions to nonlinear Schrödinger equations with variable coefficients

open access: yesAdvanced Nonlinear Studies
The existence of L 2–normalized solutions is studied for the equation −Δu+μu=f(x,u)  inRN,∫RNu2dx=m. $-{\Delta}u+\mu u=f\left(x,u\right)\quad \quad \text{in} {\mathbf{R}}^{N},\quad {\int }_{{\mathbf{R}}^{N}}{u}^{2} \mathrm{d}x=m.$ Here m > 0 and f(x, s)

Existence and Multiplicity of Fast Homoclinic Solutions for a Class of Nonlinear Second-Order Nonautonomous Systems in a Weighted Sobolev Space

open access: yesJournal of Function Spaces, 2015
This paper is concerned with the following nonlinear second-order nonautonomous problem: ü(t)+q(t)u̇(t)-∇K(t,u(t))+∇W(t,u(t))=0, where t∈R, u∈RN, and K, W∈C1(R×RN,R) are not periodic in t and q:R→R is a continuous function and Q(t)=∫0t‍q(s)ds with lim|t|

Ground state solutions for a class of generalized quasilinear Schrödinger–Poisson systems

open access: yesBoundary Value Problems, 2018
This paper is concerned with the existence of ground state solutions for a class of generalized quasilinear Schrödinger–Poisson systems in R3 $\mathbb {R}^{3}$ which have appeared in plasma physics, as well as in the description of high-power ultrashort ...

The Role of Coordination Mechanisms and Transaction Costs Promoting Sustainability Performance in Agri‐Food Supply Chains: Evidence From Ecuador

open access: yesAgribusiness, EarlyView.
ABSTRACT Social tensions and resource depletion pose significant challenges to the agri‐food sector, highlighting the need for coordinated strategies to ensure sustainability in supply chains. Despite its critical importance, the relationship between coordination mechanisms and sustainability performance remains underexplored.

Mountain Passes and Saddle Points

open access: yesSIAM Review, 2015
Summary: Variational methods find solutions of equations by considering a solution as a critical point of an appropriately chosen function. Local minima and maxima are well-known types of critical points. We explore methods for finding critical points that are neither local maxima or minima, but instead are mountain passes or saddle points.

The Cost of the National Disability Insurance Scheme: Australia's Print‐Media Discourse

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT This paper examines the way that Australian newspapers have framed the cost of the National Disability Insurance Scheme (NDIS). Introduced in 2013, the NDIS represented a major change in Australia's disability support policy, moving for the first time to a nationwide universal insurance model.

The mountain pass alternative

open access: yesAdvances in Applied Mathematics, 1991
The paper develops variational methods allowing to find the critical points of a continuously differentiable functional on a real Banach space. A modification of the mountain pass lemma concerning sequences that tend to the studied critical points is given.

Cost Utility Analysis of Fluticasone Exhalation Delivery System Versus Budesonide Nasal Irrigation for Chronic Rhinosinusitis With Nasal Polyps

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis with nasal polyps (CRSwNP) is managed after sinus surgery with topical corticosteroids. Given limited distribution of nasal steroid sprays, patients have the option of either steroid nasal irrigation (SNI) or exhalation delivery system with fluticasone (EDS‐FLU).

Lysyl Oxidase Reduces Neutrophil Extravasation in Response to P. aeruginosa in an Infection‐on‐a‐Chip Model

open access: yesAdvanced NanoBiomed Research, EarlyView.
Lysyl oxidase crosslinking of type I collagen decreases neutrophil extravasation through an endothelium during the initial response to P. aeruginosa. This decrease in extravasation is likely due to the increase in VE‐cadherin expression between endothelial cells seeded on LOX‐crosslinked collagen hydrogels.

ГОРНЫЙ УДАР – ПРИЧИНА ВЫБРОСА МЕТАНА В УГОЛЬНОЙ ШАХТЕ?

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2015
Предложена модель, в которой горный удар (техногенное землетрясение) – представлен как выход ударной волны на внутреннюю стенку шахты. При этом возникает волна разгрузки, растяжения, двигающаяся в обратном (вглубь стенки) направлении.
