This paper is presented in the context of sensitivity analysis (SA) of large-scale data assimilation (DA) models.We studied consistency, convergence, stability and roundoff error propagation of the reduced-space optimization technique arising in parallel 4D Variational DA problems.The results are helpful to understand the reliability of DA, to asse
Detection of dust canons and Physico-chemical analysis of its particles in Dezful area
To identify the physicochemical and atmospheric conditions of a dust storm at the Dezful station (As Dezful Regional Representative), at first the frequency of the dust storm phenomena was investigated at the Dezful station in Twenty years (1994 -2013).During three events on June 24, July 21, and July 28, 2018, dust samples were collected with sedi
Gut Microbial Influences on the Mammalian Intestinal Stem Cell Niche
The mammalian intestinal epithelial stem cell (IESC) niche is comprised of diverse epithelial, immune, and stromal cells, which together respond to environmental changes within the lumen and exert coordinated regulation of IESC behavior.There is growing appreciation for the role of the gut microbiota in modulating intestinal proliferation and diffe
Adaptive Traffic-Aware PSM Mechanism for IEEE 802.11 WLANs
Wireless devices consume large amounts of energy during wireless communication.As the energy storage of battery is limited, improving energy efficiency has become an important Bubbles approach to prolong the lifetime of devices.The IEEE 802.11 protocol supports the power save mode (PSM) in wireless local area networks (WLANs).However, the standard
