Continuous spectrum of a fourth order nonhomogeneous differential operators with variable exponent

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2013
In this article, we consider the nonlinear eigenvalue problem: $$\left\{ \begin{array}{ll} \Delta(|\Delta u|^{p_1(x)-2}\Delta u)+\Delta(|\Delta u|^{p_2(x)-2}\Delta u)=\lambda|u|^{q(x)-2}u,\ {\rm in}\ \Omega, & \\ u=\Delta u=0,\ {\rm on ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Critical Point Theorems and Ekeland Type Variational Principle with Applications

open access: yes, 2011
[[abstract]]We introduce the notion of  λ-spaces which is much weaker than cone metric spaces defined by Huang and X. Zhang (2007). We establish some critical point theorems in the setting of  λ-spaces and, in particular, in the setting of complete cone ...

Nematic quantum critical point without magnetism in FeSe1−xSx superconductors

open access: yes, 2016
In most unconventional superconductors, the importance of antifer- romagnetic fluctuations is widely acknowledged. In addition, cuprate and iron-pnictide high-temperature superconductors often exhibit unidirectional (nematic) electronic correlations ...

Existence of solutions to fractional Hamiltonian systems with combined nonlinearities

open access: yesElectronic Journal of Differential Equations, 2016
This article concerns the existence of solutions for the fractional Hamiltonian system $$\displaylines{ - _tD^{\alpha}_{\infty}\big(_{-\infty}D^{\alpha}_{t}u(t)\big) -L(t)u(t)+\nabla W(t,u(t))=0,\cr u\in H^{\alpha}(\mathbb{R},\mathbb{R}^n ...

Estimation of bulk modulus of DME on the basis of the sound speed measurement in a wide range of pressures and temperatures including the critical point

open access: yesNihon Kikai Gakkai ronbunshu, 2018
Sound speed is one of the most important thermodynamic properties for developing a fuel injection system and it is often used to validate the equation of state.

The human gut microbiome across the life course

open access: yesFEBS 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.

Critical-point model dielectric function analysis of WO$_3$ thin films deposited by atomic layer deposition techniques

open access: yes, 2018
WO3 thin films were grown by atomic layer deposition and spectroscopic ellipsometry data gathered in the photon energy range of 0.72-8.5 eV and from multiple samples was utilized to determine the frequency dependent complex-valued isotropic dielectric ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...
