Mountain pass solutions for nonlocal equations

open access: yesAnnales Academiae Scientiarum Fennicae Mathematica, 2014
In this paper, the authors study the following nonlocal Dirichlet problem: \[ \left\{\begin{aligned} &\left[M\Big(\int_{\Omega} |\nabla u(x)|^p\,dx\Big)\right]^{p-1}\Delta_pu = f(x,u) \quad \text{in } \Omega, \\ &u|_{\partial\Omega} =0, \end{aligned}\right.

Ratoon Season Rice Reduces Methane Emissions by Limiting Acetic Acid Transport to the Rhizosphere and Inhibiting Methanogens

open access: yesAdvanced Science, EarlyView.
This study finds that the interaction between ABA‐OsCIPK2‐OsSWEET1A reduces the allocation of methane producing bacteria carbon source (acetic acid) content to the rhizosphere soil of ratoon season rice, thereby reducing methane emissions. Abstract Rice paddies are a major, persistent source of atmospheric methane (CH4), emission rates depend on the ...

Retracted: Can the chemical industry solve the climate change?On the role of human energy production, renewable energies, and the potential of chemistry as a solution provider

open access: yesChemie Ingenieur Technik, EarlyView., 2023
Let us consider an alternative perspective on climate change: The sum of solar radiation and heat generated by human activity result in a net energy input of 1.96 times that of the Sun on the Earth's surface. The expanding global population is expected to exacerbate this issue. Potential solutions are proposed, including replacement and heat recycling.

Needle‐free, Liquid Metal‐embedded Electrospray Deposition System for Controlled Microdroplet Printing

open access: yesAdvanced Science, EarlyView.
The liquid metal‐embedded electrospray deposition (LM‐ESD) system combines stable droplet spray, clog‐free and recoverable operation, and simplified fabrication in a single polydimethylsiloxane (PDMS) microfluidic platform. By eliminating external electrodes, it offers needle‐free, robust, and scalable droplet array printing, ensuring reproducibility ...

Periodic solutions for second-order Hamiltonian systems with the p-Laplacian

open access: yesElectronic Journal of Differential Equations, 2006
In this paper, we investigate the periodic solutions of Hamiltonian system with the p-Laplacian. By using Mountain Pass Theorem the existence of at least one periodic solution is obtained, Furthermore, under suitable assumptions, we obtain the ...

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 ...

Acute mountain sickness: the "poison of the pass" [PDF]

open access: yesWestern Journal of Medicine, 2000
Few sights are more breathtaking and inspirational than a mountain peak. Yet, behind the innocence and majesty of one of nature's wonders lies a sleeping evil, acute mountain sickness (AMS). The constellation of symptoms that characterizes AMS is a frequent cause of morbidity and occasionally mortality and affects 25% of travelers sojourning to ...
