Anti-periodic solutions for high-order cellular neural networks with time-varying delays

Electronic Journal of Differential Equations, 2010
In this article, we study anti-periodic solutions for high-order cellular neural networks with time-varying delays. Sufficient conditions for the existence and exponential stability of anti-periodic solutions are presented.

Sensorless anti-control and synchronization of chaos of brushless DC motor driver

Scientific Reports
Anti-control and synchronization of period doubling and chaos is a method for bifurcation control. It can be used to detect the occurrence or periodic behavior of a bifurcation at the specified position to meet the requirements of brushless direct ...

Twisted Heisenberg chain and the six-vertex model with DWBC

, 2013
In this work we establish a relation between the six-vertex model with Domain Wall Boundary Conditions (DWBC) and the $XXZ$ spin chain with anti-periodic twisted boundaries.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Anti-periodic solutions for recurrent neural networks without assuming global Lipschitz conditions

Electronic Journal of Differential Equations, 2010
In this paper we study recurrent neural networks with time-varying delays and continuously distributed delays. Without assuming global Lipschitz conditions on the activation functions, we establish the existence and local exponential stability of ...

$(\omega,c)$-periodic functions and mild solutions to abstract fractional integro-differential equations

Electronic Journal of Qualitative Theory of Differential Equations, 2018
In this paper we study a new class of functions, which we call $(\omega,c)$-periodic functions. This collection includes periodic, anti-periodic, Bloch and unbounded functions.

The energy spectrum of complex periodic potentials of the Kronig-Penney type

, 1999
We consider a complex periodic PT-symmetric potential of the Kronig-Penney type, in order to elucidate the peculiar properties found by Bender et al.

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Reduction of Surface Reflection on Dielectric Lens Antenna by Matching Periodic Square-Pillars in 300-GHz Band

IEEE Access, 2023
This study proposes a dielectric lens antenna that implements an impedance matching layer comprising square-pillar periodic structures on the lens surface to reduce the surface reflection formed in the lens from a high-permittivity dielectric material ...
