Multiplicity Results for a Perturbed Elliptic Neumann Problem

open access: yesAbstract and Applied Analysis, 2010
The existence of three solutions for elliptic Neumann problems with a perturbed nonlinear term depending on two real parameters is investigated. Our approach is based on variational methods.

Pharmaceutical Pricing and R&D as a Global Public Good

open access: yesHealth Economics, EarlyView.
ABSTRACT This paper examines the international variation in the prices of branded pharmaceuticals. We consider short‐run profits, or quasi‐rents, as representing each country's contribution toward the global public good of therapeutic information embodied in new pharmaceuticals.

Bio‐inspired inorganic/organic semiconductor heterostructure synapses with UV–visible–NIR wavelength‐dependent responses for image recognition

open access: yesInfoMat, EarlyView.
This study presents a SnSe2/DNTT heterostructure photonic synaptic transistor that exhibits wavelength‐dependent photoresponses and synaptic plasticity. Operating with low energy consumption, the device extends spectral sensitivity from ultraviolet (UV) to near‐infrared (NIR) wavelengths, significantly enhancing neuromorphic computing performance.

New Drain Spacing Formulas Using the Variational Iteration Method

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT In this study, the drain spacing is computed using the variational iteration method (VIM) to the linearized Boussinesq equation. By applying at most two iterations of the VIM method under three different initial condition scenarios, three equations for drain spacing calculation were derived. These equations predict values of drain spacing that

Between Dependence and Alienation: Understanding the Digital Minimalist Behavior of Chinese Millennials—An Analysis Based on SEM and fsQCA

open access: yesJournal of Adolescence, EarlyView.
ABSTRACT Introduction Following rapid iterations in media technologies, Chinese millennials (born between 1980 and 1995) find themselves in a paradoxical state where digital saturation exists alongside fatigue, making them central practitioners of digital minimalist behavior.

A Variational Approach for the Neumann Problem in Some FLRW Spacetimes

open access: yesAdvanced Nonlinear Studies, 2019
In this paper, we study, using critical point theory for strongly indefinite functionals, the Neumann problem associated to some prescribed mean curvature problems in a FLRW spacetime with one spatial dimension.

An inverse Neumann problem

open access: yes
We prove that the only domains \(\Omega\) in \({\mathbb{R}}^ n\) (resp. \({\mathbb{N}}^ n)\) (n\(\geq 2)\) such that \(\partial \Omega\) is Lipschitz, connected and one of the following overdetermined boundary value problems (D) or (N) has infinitely many solutions. Are the balls in \({\mathbb{R}}^ n\) (resp.

Sequelae of child maltreatment: Umbrella synthesis of 148 meta‐analyses on the mental health correlates

open access: yesJCPP Advances, EarlyView.
Our umbrella synthesis found strong, often equivalent, associations between child maltreatment and all examined mental health difficulties. Different types of maltreatment appear to have comparably negative effects on mental health. If replicated, these findings may cause us to reconsider conventional wisdom that suggests some forms of CM are less ...

Psychological Contracts With Purpose: A Review and Path Forward

open access: yesJournal of Organizational Behavior, EarlyView.
ABSTRACT This review advances the understanding of psychological contracts (PCs) that include third‐party beneficiaries and transcend self‐interested goals, which we term “PCs with purpose.” PC theory has challenged the assumption that social exchange relies solely on balanced rewards and inducements, highlighting that individuals may wish to ...

Fritz Scheffer Under National Socialism: Assessing His Political Involvement

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Aims This article examines the role of soil scientist Fritz Scheffer (1899–1979) under National Socialism and offers a critical assessment of his scientific, institutional, and political positioning between 1933 and 1945. It asks how Scheffer shaped his career within the tension between disciplinary specialization, political expectations, and ...
