Eigencurves of the p-Laplacian with weights and their asymptotic behavior

open access: yesElectronic Journal of Differential Equations, 2007
In this paper we study the existence of the eigencurves of the p-Laplacian with indefinite weights. We obtain also their variational formulations and asymptotic behavior.

‘A completely different space’: Teachers' perspectives on disadvantage, access to nature and outdoor learning

open access: yesBritish Educational Research Journal, EarlyView.
Abstract This study examined teachers' perspectives on how children benefit from time in nature, how disadvantage shapes access and the role of schools in facilitating such access. Drawing on interviews conducted in 2022 with 25 UK primary school teachers who participated in Generation Wild, a nature connection programme for schools in economically ...

On solvability of an indefinite Riccati equation [PDF]

open access: yes, 2013
This note concerns a class of matrix Riccati equations associated with stochastic linear-quadratic optimal control problems with indefinite state and control weighting costs. A novel sufficient condition of solvability of such equations is derived, based

Singular Sturm?Liouville problems with nonnegative and indefinite weights

open access: yesMonatshefte f�r Mathematik, 1984
This article is concerned with the oscillatory properties of the eigenfunctions of a class of singular Sturm-Liouville problems \(- (py')'+qy=\lambda wy\) on (a,b), where the weight function w vanishes on a subinterval of positive measure, or where the weight function w changes sign on (a,b).

Multiplicity of solutions for gradient systems

open access: yesElectronic Journal of Differential Equations, 2010
We establish the existence of nontrivial solutions for an elliptic system which is resonant both at the origin and at infinity. The resonance is given by an eigenvalue problem with indefinite weight, and the nonlinear term is permitted to be unbounded.

Variability in UK Body Donation Information: A Comparison of Bequeathal Information and Consent Forms With Recommendations for Standardization

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The use of human donor bodies for anatomical examination in the United Kingdom is regulated by the Human Tissue Authority (England, Wales, and Northern Ireland) and His Majesty's Inspector of Anatomy for Scotland. This study aimed to assess the variability of information provided to body donors and the associated consent forms across UK ...

Alternative Price Dynamics and Valuation of Flexible Strategies

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT In this article, we study the optimal operational strategy of production projects. We investigate different underlying price models and determine the optimal barriers of transition to suspension, recovery, or irreversible abandonment of productive activity.

t-Exponential Memory Networks for Question-Answering Machines

open access: yes, 2018
Recent advances in deep learning have brought to the fore models that can make multiple computational steps in the service of completing a task; these are capable of describ- ing long-term dependencies in sequential data. Novel recurrent attention models
