We provide a general framework to study differentiability of SRB measures for one dimensional non-uniformly expanding maps. Our work covers systems that admit a finite SRB measure and it also covers systems that admit an infinite SRB measure. In particular, we obtain a linear response formula for both finite and infinite SRB measures. We apply our results to interval maps with a neutral fixed p...

A new phenolic amide 8, together with the nine known phenolic compounds 1-7, 9 and 10 were isolated from the MeOH extract of the roots of Paris verticillata. The structure of the new compound 8 was determined to be 1-N-feruloylaminobutyl-4-rho-hydroxybenzamide by spectroscopic methods. The isolated compounds were tested for cytotoxicity against four human tumor cell lines using the SRB assay.

OBJECTIVE This study aimed to evaluate the influence of different laser therapy energy densities on SHED viability and proliferation. MATERIAL AND METHODS SHED were irradiated according to the groups: I (1.2 J/cm2 - 0.5 mW - 10 s), II (2.5 J/cm2 - 10 mW - 10 s), III (3.7 J/cm2 - 15 mW - 10 s), IV (5.0 J/cm2 - 20 mW - 10 s), V (6.2 J/cm2 - 25 mW - 10 s), and VI (not irradiated - control group)...

AIMS To develop and evaluate primer sets targeted to the dissimilatory sulfite reductase gene (dsrA) for use in quantitative real-time PCR detection of sulfate-reducing bacteria (SRB) in stored swine manure. METHODS AND RESULTS Degenerate primer sets were developed to detect SRB in stored swine manure. These were compared with a previously reported primer set, DSR1F+ and DSR-R, for their cove...

The current study utilized a sample of 123 inner-city drug users in residential treatment, comparing sexual risk behavior (SRB) across primary users of (a) heroin and not crack/cocaine, (b) crack/cocaine and not heroin, and (c) both heroin and crack/cocaine. Additional analyses also examined impulsivity as a mediator of drug choice and SRB. Results indicated that SRB was higher in primary crack...

I n industrial countries sex ratio at birth (SRB) (male/ female) varies between 1.07 and 1.03, with a decreasing trend in the past few decades. Population statistics of the past 20 years report that SRB in China is constantly and considerably increasing. According to official census data, the SRB of Chinese newborn babies was 1.168 in 2000 but in some provinces it exceeded 1.3. The increase of ...

Large-scale parallel scientific applications are generating huge amounts of data that tertiary storage systems emerge as a popular place to hold them. SRB, a uniform interface to various storage systems including tertiary storage systems such as HPSS, UniTree etc., becomes an important and convenient way to access tertiary data across networks in a distributed environment. But SRB is not optimi...

For any continuous map f : M → M on a compact manifold M , we define the SRB-like probabilities as a generalization of Sinai-Ruelle-Bowen (i.e. physical) measures. We prove that f has SRB-like measures, even if SRB measures do not exist. We prove that the definition of SRB-like measures is optimal, provided that the purpose of the researcher is to describe the asymptotic statistics for Lebesgue...

Sulfate-reducing bacteria (SRB) have been studied extensively in the petroleum industry due to their role in corrosion, but very little is known about sulfur-oxidizing bacteria (SOB), which drive the oxidization of sulfur-compounds produced by the activity of SRB in petroleum reservoirs. Here, we surveyed the community structure, diversity and abundance of SRB and SOB simultaneously based on 16...

The membrane biofilm reactor (MBfR) is a novel technology that safely delivers hydrogen to the base of a denitrifying biofilm via gas-supplying membranes. While hydrogen is an effective electron donor for denitrifying bacteria (DNB), it also supports sulfate-reducing bacteria (SRB) and methanogens (MET), which consume hydrogen and create undesirable by-products. SRB and MET are only competitive...
