Availability of accurate and objective landslide susceptibility maps depicting zones defined on the basis of probability of occurrence of landslides is one of the critical inputs in assessing risk to property and lives in any mountainous region, particularly in the Himalayas. The aim of this study is to assess the utility of soft computing tools, namely, neural network, fuzzy and neuro-fuzzy ap...
Environmental hazards are considered as one of the factors threatening human societies. Identification areas susceptible landslides risk assessment of natural hazards and management of are the essential steps in the city's watershed. The purpose of this study is landslides hazard zonation in Izeh urban watersheds of East Khuzestan. In this research First, eight layers effective in landslid...
Hepatocytes are functionally heterogeneous and are divided into two distinct populations based on their metabolic zonation: the periportal and pericentral hepatocytes. During liver injury and regeneration, the cellular dynamics of these two distinct populations remain largely elusive. Here we show that major facilitator super family domain containing 2a (Mfsd2a), previously known to maintain bl...
Increasingly, spatial geochemical zonation, present as geographically distinct, subparallel trends, is observed along hotspot tracks, such as Hawaii and the Galapagos. The origin of this zonation is currently unclear. Recently zonation was found along the last ∼70 Myr of the Tristan-Gough hotspot track. Here we present new Sr-Nd-Pb-Hf isotope data from the older parts of this hotspot track (Wal...
In this paper the geological structure and earthquake activity nearby Kunming Basin, Yunnan, China, have been studied. Different ground motion attenuation models used in Japan and in Yunnan, China, have been reviewed, and quantitative comparisons between the models have been made. The zonation of peak horizontal acceleration corresponding to a seldom happened earthquake and the zonation of the ...
Today, urban and regional issues related to sustainable development is a key challenge for policy-makers, planners and specialists in various disciplines. Geomorphologic studies can be useful and effective in analyzing and deriving acceptable means to assess the growth and development of the city, and to set criteria to determine the directions of urban development. Landslides ran...
The most widespread reserve selection strategy is target-based planning, as specified under the framework of systematic conservation planning. Targets are given for the representation levels of biodiversity features, and site selection algorithms are employed to either meet the targets with least cost (the minimum set formulation) or to maximize the number of targets met with a given resource (...
Concomitant steatosis in chronic hepatitis C is associated with fibrosis and unfavorable treatment outcome. Central zone injury in nonalcoholic steatohepatitis (NASH) manifests as central portalization, with centrizonal microvessels and ductular reaction. We investigated whether central portalization in steatotic HCV biopsies would identify patients with metabolic risk factors for NASH. Liver b...
Using game theory and reinforcement learning, we created and analyzed generalized agent-based and compartmental models of hepatic toxin elimination processes to explore plausible causes of hepatic functional zonation. We considered a general situation in which a group of protective agents (analogous to liver cells) cooperate and self-organize their efforts to minimize optimally the negative eff...
