Exact Solutions to the Sine-Gordon Equation [PDF]

, 2010
A systematic method is presented to provide various equivalent solution formulas for exact solutions to the sine-Gordon equation. Such solutions are analytic in the spatial variable $x$ and the temporal variable $t,$ and they are exponentially asymptotic

Rotor-System Log-Decrement Identification Using Short-Time Fourier-Transform Filter

International Journal of Rotating Machinery, 2015
With the increase of the centrifugal compressor capability, such as large scale LNG and CO2 reinjection, the stability margin evaluation is crucial to assure the compressor work in the designed operating conditions in field.

New single-carrier transceiver scheme based on the discrete sine transform

The Journal of Engineering, 2014
A discrete sine transform (DST)-based single-carrier transceiver scheme for broadband wireless communications is proposed and investigated. The proposed scheme uses a DST rather than the conventional discrete Fourier transform (DFT) as a basis function ...

XPO1-dependent nuclear export as a target for cancer therapy

Journal of Hematology & Oncology, 2020
Cellular homeostasis requires the proper nuclear-cytoplasmic partitioning of large molecules, which is often deregulated in cancer. XPO1 is an export receptor responsible for the nuclear-cytoplasmic transport of hundreds of proteins and multiple RNA ...

Molecular regulatory mechanism of LILRB4 in the immune response

Central European Journal of Immunology, 2023
Immune diseases are caused by the imbalance of immune regulation. This imbalance is regulated by many factors, both negative and positive. Leukocyte immunoglobulin-like receptor B4 (LILRB4) is a member of leukocyte immunoglobulin-like receptors (LILRs ...

An Accelerated Double-Integral ZNN with Resisting Linear Noise for Dynamic Sylvester Equation Solving and Its Application to the Control of the SFM Chaotic System

Axioms, 2023
The dynamic Sylvester equation (DSE) is frequently encountered in engineering and mathematics fields. The original zeroing neural network (OZNN) can work well to handle DSE under a noise-free environment, but may not work in noise.

Frequency Recognition in SSVEP-based BCI using Multiset Canonical Correlation Analysis [PDF]

, 2014
Canonical correlation analysis (CCA) has been one of the most popular methods for frequency recognition in steady-state visual evoked potential (SSVEP)-based brain-computer interfaces (BCIs).

Impacting T-cell fitness in multiple myeloma: potential roles for selinexor and XPO1 inhibitors

Frontiers in Immunology, 2023
Competent T-cells with sufficient levels of fitness combat cancer formation and progression. In multiple myeloma (MM), T-cell exhaustion is caused by several factors including tumor burden, constant immune activation due to chronic disease, age ...

On the transition from parabolicity to hyperbolicity for a nonlinear equation under Neumann boundary conditions

, 2018
An integro differential equation which is able to describe the evolution of a large class of dissipative models, is considered. By means of an equivalence, the focus shifts to the perturbed sine- Gordon equation that in superconductivity finds ...

Enhanced Chaotic Pseudorandom Number Generation Using Multiple Bernoulli Maps with Field Programmable Gate Array Optimizations

Information
Certain methods for implementing chaotic maps can lead to dynamic degradation of the generated number sequences. To solve such a problem, we develop a method for generating pseudorandom number sequences based on multiple one-dimensional chaotic maps.
