Sign-changing solutions of variational inequality [PDF]

In this paper, we are concerned with the sign-changing solutions of variational inequality problems. In order to give the existence results of the sign-changing solutions for variational inequality problems, we first construct a suitable penalty problem ...

Sign-Changing Solutions of Fractional 𝑝-Laplacian Problems

Advanced Nonlinear Studies, 2019
In this paper, we obtain the existence and multiplicity of sign-changing solutions of the fractional p-Laplacian problems by applying the method of invariant sets of descending flow and minimax theory.

The fundamental solution of a 1D evolution equation with a sign changing diffusion coefficient [PDF]

, 2022
In this work we investigate a 1D evolution equation involving a divergence form operator where the diffusion coefficient inside the divergence is sign changing. Equivalently the evolution equation of interest can be interpreted as behaving locally like a

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Sign-changing solutions of a fourth-order elliptic equation with supercritical exponent

Electronic Journal of Differential Equations, 2014
In this article we study the nonlinear elliptic problem involving nearly critical exponent $$\displaylines{ \Delta^2 u = |u|^{8/(n-4)+\varepsilon}u\quad\text{in } \Omega, \cr \Delta u=u = 0\quad \text{on } \partial \Omega, }$$ where $\Omega $ is a

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Existence of infinitely many sign-changing solutions for elliptic problems with critical exponential growth

Electronic Journal of Differential Equations, 2015
In this work we prove the existence of infinitely many nonradial solutions, that change sign, to the problem $$\displaylines{ -\Delta u=f(u)\quad\text{in }B\cr u=0\quad\text{on }\partial B, }$$ where B is the unit ball in $\mathbb{R}^2$ and f is a

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Hand in hand: automatic sign Language to English translation [PDF]

, 2007
In this paper, we describe the first data-driven automatic sign-language-to- speech translation system. While both sign language (SL) recognition and translation techniques exist, both use an intermediate notation system not directly intelligible for ...
