In the present study Iran’s rice imports trend is forecasted, using artificial neural networks and econometric methods, during 2009 to 2013, and their results are compared. The results showed that feet forward neural network leading with less forecast error and had better performance in comparison to econometric techniques and also, other methods of neural networks, such as Recurrent networks a...

In this research, the DCC model is estimated to calculate dynamic correlation series between crude oil price and growth of Industry and Mine sector during 1367:1-1392:4. Then, Macroeconomic variables which can explain the dynamic correlation are analyzed as variables of contagion. So, the import, as an effective and affected variable from crude oil price, is separated to real import of consumpt...

The TIM23 complex mediates translocation of proteins across, and their lateral insertion into, the mitochondrial inner membrane. Translocation of proteins requires both the membrane-embedded core of the complex and its ATP-dependent import motor. Insertion of some proteins, however, occurs in the absence of ATP, questioning the need for the import motor during lateral insertion. We show here th...

The Saccharomyces cerevisiae F1-ATPase beta subunit precursor contains redundant mitochondrial protein import information at its NH2 terminus (D. M. Bedwell, D. J. Klionsky, and S. D. Emr, Mol. Cell. Biol. 7:4038-4047, 1987). To define the critical sequence and structural features contained within this topogenic signal, one of the redundant regions (representing a minimal targeting sequence) wa...

Although much is known about the mechanisms of signal-mediated protein and RNA nuclear import and export, little is understood concerning the nuclear import of plasmid DNA. Plasmids between 4.2 and 14.4 kilobases were specifically labeled using a fluorescein-conjugated peptide nucleic acid clamp. The resulting substrates were capable of gene expression and nuclear localization in microinjected ...

Infection of non-dividing cells is a biological property of HIV-1 crucial for virus transmission and AIDS pathogenesis. This property depends on nuclear import of the intracellular reverse transcription and pre-integration complexes (RTCs/PICs). To identify cellular factors involved in nuclear import of HIV-1 RTCs, cytosolic extracts were fractionated by chromatography and import activity exami...

The United States and Brazil both have many local consumer markets which imported cement can access by waterway. Despite this similarity, the degree of import penetration is strikingly di¤erent. While imports from around the world account for as much as 30% of U.S. cement consumption, Brazil hardly imports cement. U.S. cement producers, facing lower inbound trade costs and higher marginal costs...
