We review the basic steps leading to the construction of a Sinai-Ruelle-Bowen (SRB) measure for an innnite lattice of weakly coupled expanding circle maps, and we show that this measure has exponential decay of space-time correlations. First, using the Perron-Frobenius operator, one connects the dynamical system of coupled maps on a d-dimensional lattice to an equilibrium statistical mechanical...

BACKGROUND Arsenic (As) toxicity is primarily based on its chemical speciation. Although inorganic and methylated As species are well characterized in terms of metabolism and formation in the human body, the origin of thiolated methylarsenicals is still unclear. OBJECTIVES We sought to determine whether sulfate-reducing bacteria (SRB) from the human gut are actively involved in the thiolation...

In this article we give the detailed proof of the entropy formula for SRB-measures of coupled hyperbolic map lattices. We show that the topological pressure for the potential function of the SRB-measure is zero.

Thirteen novel cinnamamide-chalcone derivatives were synthesized and tested for their antiproliferative activity against MCF-7, K562, U-373MG, HT-29 cell lines using SRB assay. Eight compounds the in vitro CDK2 inhibition. Compounds 2g, 2h, 2k, 2l found to have IC50 < 10 µM CDK2. These four evaluated on EGFR kinase be two times more selective docked into Glide software. The docking studies reve...

OBJECTIVE The accuracy of a population-based sex ratio at birth (SRB) in China has long been questioned. To depict a more accurate profile, the present study used data from a national surveillance system for health facility births to explore the characteristics of SRB in China. METHODS Data from China's National Maternal Near Miss Surveillance System between 2012 and 2015 were used. We restri...

Sulfate-reducing bacteria (SRB) in anoxic waters and sediments are the major producers of methylmercury in aquatic systems. Although a considerable amount of work has addressed the environmental factors that control methylmercury formation and the conditions that control bioavailability of inorganic mercury to SRB, little work has been undertaken analyzing the biochemical mechanism of methylmer...

Abstract The potential for crevice corrosion of UNS30400 stainless steel in the presence sulfate-reducing bacteria (SRB) was studied different media. Immersion studies found to occur test media supplemented with high chloride levels and SRB present gaps ~3 μm. Electrochemical measurements showed susceptibility this particular medium, demonstrated by a negative shift open circuit potential, incr...

euphorbia wallichii a perennial herb growing mainly in himalayas has been widely used in folk medicines for its medicinal properties. in the present study, the crude methanolic root extract (cme) and its fractions; n-hexane fraction (nhf), n-butanol fraction (nbf), chloroform fraction (chf), ethyl acetate fraction (eaf) and aqueous fraction (aqf) of this plant specie were investigated for antio...

We find that AGB stars separate in the 25-12 vs. 12-K color-color diagram according to their chemistry (O, S vs. C) and variability type (Miras vs. SRb/Lb). While discrimination according to the chemical composition is not surprising, the separation of Miras from SRb/Lb variables is unexpected. We show that “standard” steady-state radiatively driven models provide excellent fits to the color di...
