Current‐Limiting Control Strategies in Variable Capacitance Electrostatic Energy Harvesters

Advanced Intelligent Systems, EarlyView.
This work introduces control strategies for electrostatic energy harvesters that balance energy yield with current limitations. Two approaches are explored: traditional peak‐triggered controls, and newly developed quadrature controls, which use smooth voltage profiles.

“You're this person who's providing light”: Embodied responses to information loss and transition within LGBTQIA+ communities

Journal of the Association for Information Science and Technology, EarlyView.
Abstract This paper reports on findings from 15 semi‐structured interviews with LGBTQIA+ individuals within the United States who have experienced the loss of one or more LGBTQIA+ information spaces. The paper specifically focuses on how such losses occurred and the information transitions experienced by the participants in response to this loss ...

Maximum and antimaximum principles for the $p$-Laplacian with weighted Steklov boundary conditions

Electronic Journal of Differential Equations, 2020
We study the maximum and antimaximum principles for the p-Laplacian operator under Steklov boundary conditions with an indefinite weight $$\displaylines{ -\Delta_p u + |u|^{p-2}u = 0 \quad \text{in }\Omega, \cr |\nabla u|^{p-2}\frac{\partial u ...

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

British 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 ...

Singular Sturm?Liouville problems with nonnegative and indefinite weights

Monatshefte 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).

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

Clinical 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

International 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.

Market Expansion and Business Stealing With Differentiated Products Using a Nested Logit

Journal of Applied Econometrics, EarlyView.
ABSTRACT In this paper, we use the widely adopted nested logit model to examine how introducing a new product into a market of highly substitutable, differentiated goods affects both market expansion and business stealing. Central to our analysis is the nesting parameter σ$$ \sigma $$, which captures the correlation in consumers' unobserved utilities ...
