we prove a strong convergence result for a sequence generated by halpern's type iteration for approximating a common fixed point of a countable family of quasi-lipschitzian mappings in a real hilbert space. consequently, we apply our results to the problem of finding a common fixed point of asymptotically nonexpansive mappings, an equilibrium problem, and a variational inequality problem for co...

BACKGROUND Neuroimaging studies of ultra-high risk (UHR) and first-episode psychosis (FEP) have revealed widespread alterations in brain structure and function. Recent evidence suggests there is an intrinsic relationship between these 2 types of alterations; however, there is very little research linking these 2 modalities in the early stages of psychosis. METHODS To test the hypothesis that ...

background: evaluation on the toxicity of two mainly contaminant heavy metals, cadmium (cd) and lead (pb) through the food chain was the aim of this study. methods: a total number of 270 healthy common carp (4±1.14 g) in april, 2015 transported to the khatam alanbia university of technology, behbahan, iran. fishes were divided into three groups and transferred to the 20 l aquaria each containin...

taknar deposit is located about 28 km to the north-west of bardaskan in the khorasan-e-razavi province, which is situated in the north-eastern part of iran. this deposit is unique, formed within the taknar formation in the ordovician time. as a result, it is of much interest to many researchers working in this field. by choosing the lithogeochemical study performed to recognize new exploration ...

one of the major strengths of a geographic information system (gis) in geosciences is the ability to integrate and combine multiple layers into mineral potential maps showing areas which are favorable for mineral exploration. these capabilities make gis an extremely useful tool for mineral exploration. several spatial modeling techniques can be employed to produce potential maps. however, these...

Most geoscientists are familiar with the colorful LandSat imagery we have been provided with for almost 30 years. These multispectral data sets have allowed us to see the earth in colors not accessible to the human eye and hence allowed discrimination of previous, not distinguishable geological features. Technology has progressed and it is now possible to view the earth not only in a few, but h...

A scalable laser-based timing analysis technique we call laser assisted device alteration (LADA) is introduced for the rapid isolation and analysis of defect-free performance limiting circuits in advanced flip-chip packaged microprocessors and other complex IC’s. The technique, which has been demonstrated to be widely applicable to production level as well as motherboard/system level testing, u...

A mucopolysaccharide inhibitor of Theiler's GDVII virus has been purified from intestinal tissue of adult mice. The purified material has been shown to consist chiefly of carbohydrate. Following acid hydrolysis of the inhibitor, several amino adds were found to be present. The carbohydrate components shown to be present thus far are galactose, hexosamine, N-acetylhexosamine, methylpentose, hexu...

the present study was conducted to determine the relative contribution of initial quality and compositional parameters to the rate of changes (rctpc) in the content of total polar compounds (tpc), which is considered to be one of the most reliable indicators of heated oils quality, of olive oil during continuous heating at 180 ºc. the ratio between monounsaturated and polyunsaturated fatty acid...
