Using a variety of different definitions of “neutrality,” this study presents significant evidence against the neutrality to market risk of hedge funds in a range of style categories. I generalize standard definitions of “market neutrality,” and propose five different neutrality concepts. I suggest statistical tests for each neutrality concept, and apply these tests to a database of monthly ret...

Introduction: Emotional words in comparison with neutral words have different hemispheric specialization. It is assumed that the right hemisphere has a role in processing every kind of emotional word. The objective of the present study was the development of a Persian version of the dichotic emotional word test and evaluate its validation among adult Persian speakers.   Materials and Methods: ...

In this research we have developed a treatment method for textile wastewater by TiO2/SiO2-based magnetic nanocomposite. Textile wastewater includes a large variety of dyes and chemicals and needs treatments. This manuscript presents a facile method for removing dyes from the textile wastewater by using TiO2/SiO2-based nanocomposite (Fe3O<su...

Consumers’ prior experiences shape an episodic memory which largely influences their decision-making process. This episodic memory is mainly linked to cognitive and emotional perception and we know that a brand image influences our cognitive and emotional perception. Nevertheless, it has not been well described how autobiographical memories of brand images differ from those of other types of im...

keto-enol tautomerism was investigated for ionized pyruvic acid using the dft(b3lyp) method and the larger basis sets [6-31++g(d,p), 6-311++g(3df, 3pd) and aug-cc-pvdz]. change of the tautomeric preference was observed when going from the neutral to ionized tautomeric mixture. ionization favors the enolization process (ketoenol) of pyruvic acid, whereas the ketonization (ketoenol) is preferred ...

Molecular evolutionary biologists usually assess the underlying spectrum of mutations within a bacterial genome by examining substitutions that occur at sites believed to be under no selective constraints. Alternatively, bacterial mutation rates can also be estimated in a variety of experimental systems. The two classes of changes occurring in DNA sequences-i.e., mutations and neutral substitut...

This study derives kinematic admissible bending moment – axial force (M-P) interaction relations for mild steel by considering elastic-plastic idealizations. The interaction relations can predict strains, which is not possible in a rigid perfectly plastic idealization. The relations are obtained for all possible cases pertaining to the locations of neutral axis. One commercial rolled steel T-se...
