Motivated by brane cosmology we solve the Einstein equations with a time dependent cosmological constant. Assuming that at an early epoch the vacuum energy scales as 1/logt, we show that the universe passes from a fast growing phase (inflation) to an expanding phase in a natural way.

Background: Nowadays long non-coding RNAs are known as interesting functional part of the transcriptome. LncRNA SNHG6 was reported to be expressed more in breast cancer tissues than non-tumor ones. As a frequent cancer among women, breast cancer treatment needs applied biomarkers for fast prognosis and diagnosis. SNHG6 RNA and its splice variants could be considered as molecula...

Objective(s): Stroke is known as a main cause of mortality and prolonged disability in adults. Both transient receptor potential V1 (TRPV1) channels and toll-like receptors (TLRs) are involved in mediating the inflammatory responses. In the present study, the effects of TRPV1 receptor activation and blockade on stroke outcome and gene expression of TLR2 and TLR4 were assessed following permanen...

Immunohistochemical demonstration of tumor-associated markers may be valuable as an adjunct to conventional histology for determination of malignancy development in oral mucosal diseases. Accordingly, the present study determined the distribution of some important tumor markers such as heat shock proteins (HSP), fibroblast growth factors (FGF) and transferrin receptors (TF-R) in 22 samples ...

Investment projects and businesses can be entered or exited at a cost, and the theory of real option teaches us how to find optimal activity levels that should trigger entry or exit. However, in practice, different managers or owners operate under different constraints and might apply different thresholds to the same business. We are interested in the hedging of the risk related to the cost of ...

Humans are equipped with some universal or language-specific abilities to recognize emotions. However, because of the different emotional contents in diverse languages and the relevant cultural differences, humans with different cultural backgrounds own different metapragmatical abilities to recognize and express emotions. A hypothesis concerning emotional effects about intonation and particle ...

due to the abundance of the non-coking coal and limitations as well as the high costs of the natural gas, the presentstudy examined the direct reduction of hematite (iron oxide) ore in the temperature range of 800-1000 °c by thenon-coking coal volatiles. approximately, 74.9% of the total amounts of volatiles and gases exit the coal up to800°c. the onset temperature to exit volatiles from the no...
