Existence and uniqueness of positive solutions to a quasilinear elliptic problem in $R^N$

Electronic Journal of Differential Equations, 2005
We prove the existence of a unique positive solution to the problem $$ -Delta _{p}u=a(x)f(u) $$ in $mathbb{R}^{N}$, $N>2$. Our result extended previous works by Cirstea-Radulescu and Dinu, while the proofs are based on two theorems on bounded ...

Nucleophile Exchange Mechanistic Paths in Chalcogenolate‐Dichalcogenide Systems: Insight From Computational Chemistry

European Journal of Organic Chemistry, EarlyView.
The change of the chalcogen! This computational study explores trends in Group 16 nucleophile exchange model reactions, providing mechanistic insight in gas phase and in solvent as well as biological implications, which can guide the design of improved biomimetic catalysts.

Nonexistence of global solutions for differential inequalities of Sobolev type

Electronic Journal of Differential Equations, 2014
In this article we study three differential inequalities of Sobolev type. Using Pokhozhaev's nonlinear capacity method, we provide sufficient conditions for the nonexistence of global nontrivial weak solutions to these problems.

Cytotoxicity of 19 Pesticides in Rainbow Trout Gill, Liver, and Intestinal Cell Lines

Environmental Toxicology and Chemistry, EarlyView.
Abstract The rainbow trout gill cell line (RTgill‐W1), via test guideline 249 of the Organisation for Economic Co‐operation and Development, has been established as a promising New Approach Methodology, although to advance confidence in the method more case studies are needed that: 1) expand our understanding of applicability domains (chemicals with ...

Threshold Asymmetric Conditional Autoregressive Range (TACARR) Model

Journal of Forecasting, EarlyView.
ABSTRACT This paper introduces a Threshold Asymmetric Conditional Autoregressive Range (TACARR) model for analyzing the daily price ranges of financial assets. The proposed formulation assumes that the conditional expected range switches between two regimes, representing upward and downward market states, with the disturbance distribution also allowed ...

Nonexistence of solutions for quasilinear elliptic equations with p-growth in the gradient

Electronic Journal of Differential Equations, 2002
We study the nonexistence of weak solutions in $W^{1,p}_{{ m loc}}(Omega)$ for a class of quasilinear elliptic boundary-value problems with natural growth in the gradient.

On the Existence of Nonexistence Commitments

Grazer Philosophische Studien
Abstract In this article, I introduce a new kind of ontological commitment, according to which one is committed to the nonexistence of some entity. I start with an analysis of ontological commitment which gives prominence to Putnam’s notion of “intellectual honesty” and proceed to argue that whatever the correct view of ontological commitment is, there

Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

Food Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Health and Economic Impacts of an Early Labor Induction Policy for High‐BMI Mothers

Health Economics, EarlyView.
ABSTRACT We expand the literature on marginal returns to birth interventions by studying a common intervention: early induction of labor for a growing share of pregnancies, high‐Body Mass Index (BMI) women. We exploit Danish guidelines which recommend routine induction at 7 days after the expected due date instead of 10–13 days after for mothers with a

Nonexistence results for weighted p-Laplace equations with singular nonlinearities

Electronic Journal of Differential Equations, 2019
In this article we present some nonexistence results concerning stable solutions to the equation $$ \hbox{div}\big(w(x)|\nabla u|^{p-2}\nabla u\big) =g(x)f(u)\quad \text{in }\mathbb{R}^N,\;p\geq 2 $$ when f(u) is either $u^{-\delta}+u^{-\gamma ...
