过去的几十年里,尽管对互惠合作系统稳定性的理解取得了较大的进展,但在解释互惠关系如何保持稳定方面仍然存在两个基本问题。(i)如何解决互惠合作双方之间的资源冲突?(ii)当存在不怎么合作和/或完全不合作的共生体时,为什么合作的共生体没有被不合作的个体竞争排斥掉?过去许多关于互惠稳定性的解释都假设互惠合作双方的相互作用是对称的。然而,在大多数共生关系中,宿主和共生体之间的相互作用在不同水平上表现出不同程度的非对称性。本文我们回顾了互惠合作系统中的三种主要的非对称相互作用:(i)收益非对称,也就是合作双方的实力非对称性;(ii)潜在进化速率非对称性;(iii)宿主和共生体之间的信息非对称性。我们认为,互惠合作系统非对称性有助于解释合作和冲突行为的不确定性(合作与竞争的内生不确定性),以及为什么宿主和共生体都呈现出多样化的表型特征,而合作仍可占主导地位。

The aim of this research paper is to model the effects of misidentification in the transmissiondynamics of the super yeast, Candida auris (or C. auris), among patients receivingtreatment in the Intensive Care units (ICus). The mathematical analysis is carried outby obtaining the reproduction number of the C. auris model using the next generationmatrix and utilizing it as a threshold value to establish the local and global stabilityproperties at the points of equilibria. The numerical investigations carried out in thispaper establish the outcomes of the effect of variations in the values of important parameterson the dynamics of C. auris colonization and infections in the health care *** corresponding results from the numerical simulations are illustrated graphically.

How the Flat Space Cosmology Model Correlates the recombination CMB Temperature of 3000 k with a redshift of 1100

引用

Journal of Modern Physics 2024年第2期15卷 174-178页

作者： Eugene Terry Tatum u. V. S. Seshavatharam Independent researcher Bowling Green Kentucky USA I-SErVE Hitech City Hyderabad India

This paper shows how the Flat Space Cosmology model correlates the recom-bination epoch CMB temperature of 3000 k with a cosmological redshift of 1100. This proof is given in support of the recent publication that the Tatum and Seshavatharam Hubble temperature for.u.ae can be derived using the Stephan-Boltzmann dispersion law. Thus, as explained herein, the era of high precision Planck scale quantum cosmology has arrived.
