in this paper, we have examined abrupt changes in volatility of tepix index in tehran stock exchange during august 23, 2010 to june 12, 2014. applying the iterated cumulative sum of squares (icss) algorithm proposed by inclan and tiao (1994) and the modified version of this algorithm consisting kappa 1 and kappa 2 test statistics developed by sansó et al. (2004), we have specified that the dete...

A paradigm shift is underway within the methodology of heterologous protein expression. Specifically, researchers are moving away from conventional techniques of cloning genes from cDNA libraries and moving toward the rational design and de novo synthesis of entire protein-coding sequences from pre-annealed oligonucleotides (Libertini and Di Donato, 1992; Gustafsson et al, 2004). It was the inv...

Obstructive sleep apnoea (OSA) is a prevalent sleep disorder characterized by upper airway obstruction during sleep, resulting in intermittent breathing pauses despite effort, reduced blood oxygen saturation, hypoxia and arousals. With prevalence in the general population estimated at 17–24% of men and 5–9% of women (Young et al. 1993; Bixler et al. 1998, 2001), OSA has been linked to the key c...

The American Clinical Magnetoencephalography Society (ACMEGS) is a professional society of physicians and other professionals with doctoral degrees “involved in clinical use of magnetoencephalography (MEG), electroencephalography (EEG), magnetic resonance imaging, or computerized axial tomography” (ACMEGS, Inc, Bylaws, 2006). The ACMEGS is primarily focused on advancing clinical applications of...

Photonic crystals (PCs) are actually implemented as biosensors [Ganesh et al., 2007], optical resonators [Karnutsch et al., 2007] and wavelength filters [D’Orazio et al., 2008; Pierantoni et al., 2006]. Other kinds of photonic crystals can be implemented by considering a periodic structure with defect line and/or central cavities. Several architectures of micro-cavities (see examples in Fig. 1 ...

Recent years have seen progress in isolation and expansion of mesenchymal cells (MSCs) from human umbilical cord tissue, namely the Wharton’s jelly. Situated between the subamnion and the perivascular zone that surrounds the blood vessels (Troyer & Weiss, 2008), Wharton’s jelly is a matrix of mucous connective tissue, composed of fibroblast-like stromal cells, collagen fibers and proteoglycans,...

Three new species of the spider genus Philoponella Mello-Leitão, 1917 are described: Philoponella opelli n. sp. from Brazil and Ecuador, and Philoponella fluviidulcifis n. sp. , and Philoponella duopunctata n. sp. from Brazil. New records for Philoponella vittata (Keyserling, 1881), P. republicana (Simon, 1891), P. fasciata (Mello-Leitão, 1917) and P. divisa Opell, 1979 are provided for Brazil ...
