The recent rise in atmospheric methane (CH4) concentrations accelerates climate change and offsets mitigation efforts. Although wetlands are the largest natural CH4 source, estimates of global wetland CH4 emissions vary widely among approaches taken by bottom-up (BU) process-based biogeochemical models and top-down (TD) atmospheric inversion methods. Here, we integrate in situ measurements, multi-
Aeolian sand significantly affects permafrost degradation, but the effect of the aeolian sand on the permafrost on the Qinghai-Tibet Plateau remains unknown. The sand layer thickness is critical to its role. However, little quantitative research has been conducted on the effect of the sand layer thickness on its role. In this study, using CoupModel, we investigated the differences in the impact of
The aim of this paper is to find appropriate approximate expressions of the coherent electromagnetic field scattered by a particulate slab.The exact solution of the coherent electric field to the multiple scattering problem in the slab is determined by the solution of a set of integral equations. By iterating the integral equations, an approximate solution is obtained, which approximates the solutThe aim of this paper is to find appropriate approximate expressions of thecoherent electromagnetic field scattered by a particulate slab.

Iran has witnessed an increase in cohabitation relationships, or so-called white marriages (izdiwāj-i sifīd), which has caused wide political and religious efforts in cultivating religious selves based on an Islamically defined moral order. This article examines the symbolic re-enactment of the wedding of Fatima, the daughter of the Prophet Muhammad, and Ali, the Prophet’s cousin and the first Shi
Coronavirus Disease 2019 (COVID-19) poses an enormous challenge to health care systems throughout the world, but it doesn’t affect every individual to the same extent. There is great variability in disease outcomes. Therefore, identifying the main prognostic risk factors is of paramount importance. These include increased age, skin pigmentation, obesity, pre-existing illness, and vitamin D deficie
Hepato-pulmonary shunts might develop in some patients with severe liver disease, usually when cirrhosis has developed. At this stage, a dilatation of intra-pulmonary vessels might develop causing defects in blood oxygenation. Shortness of breath is a common symptom. The disease might be asymptomatic but it has an impact of patient's quality of life. The identification of shunt dysfunction is base
