Targeted high mean arterial pressure aggravates cerebral hemodynamics after extracorporeal resuscitation in swine

open access: yesCritical Care, 2021
Background Extracorporeal cardiopulmonary resuscitation (E-CPR) is used for the treatment of refractory cardiac arrest. However, the optimal target to reach for mean arterial pressure (MAP) remains to be determined.

Proof of the Transversality for the Standard Map [PDF]

open access: yesForma, 2021
Summary: We consider the standard map. The stable and unstable manifolds of the saddle fixed point are proved to intersect transversely at the primary homoclinic point \(u\) for any parameter value. For the proof, we use the particular objects called the dominant axis (DA) and subdominant axis (SD), and symmetric periodic orbits that have orbital ...

On the Complex and Chaotic Dynamics of Standard Logistic Sine Square Map

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021
In this article, we set up a new nonlinear dynamical system which is derived by combining logistic map and sine square map in Mann orbit (a two step feedback process) for ameliorating the stability performance of chaotic system and name it Standard ...

Matching Standard and Secant Parallels in Cylindrical Projections

open access: yesISPRS International Journal of Geo-Information, 2023
Map projections are usually interpreted by mapping a sphere onto an auxiliary surface, and then the surface is developed into a plane. It is taken as a fact without proof that the parallels in which the auxiliary surface intersects the sphere are mapped ...

Quantum Chaos and Quantum Randomness—Paradigms of Entropy Production on the Smallest Scales

open access: yesEntropy, 2019
Quantum chaos is presented as a paradigm of information processing by dynamical systems at the bottom of the range of phase-space scales. Starting with a brief review of classical chaos as entropy flow from micro- to macro-scales, I argue that quantum ...

Analysis of Low Probability of Detection Capability for Chaotic Standard Map-Based FH-OFDMA System

open access: yesApplied Sciences, 2021
A frequency hopping orthogonal frequency division multiple access (FH-OFDMA) can provide low probability of detection (LPD) and anti-jamming capabilities to users against adversary detectors. To obtain an extreme LPD capability that cannot be provided by

Research on Path Planning for Robot Based on Improved Design of Non-Standard Environment Map With Ant Colony Algorithm

open access: yesIEEE Access, 2023
The maps used for the path planning of mobile robots are mostly grid maps, which are generated through independent design or sensor measurement to obtain relevant information and then modeling.

A Novel Image Encryption Scheme Based on PWLCM and Standard Map

open access: yesComplexity, 2020
In the past decades, considerable attention has been paid to the chaos-based image encryption schemes owing to their characteristics such as extreme sensitivity to initial conditions and parameters, pseudo-randomness, and unpredictability.
