The observation of chiral-induced spin selectivity (CISS) in biological molecules still awaits a full theoretical explanation. In recent Rapid Communication, Varela et al. [Phys. Rev. B 101, 241410(R) (2020)] presented model for electron transport by tunneling the presence spin-orbit interactions. They then claimed that their produces strong asymmetry due to intrinsic atomic strength. As Hamilt...

Introduction: Due to the complexity of facial asy-mmetry, the diagnosis of different aspects of asymmetry via conventional radiographs is not precise. In this study, we investigated findings of facial asymmetry by using cone- beam computed tomography (CBCT) images. Materials and Methods: In this descriptive study, we evaluated CBCT findings of 18 patients i.e. a group of 14 females and 4 males ...

background and objectives: scapular stabilization and neuromuscular control provide an important parameter to characterize shoulder function during dynamic activities. many studies have confirmed the effect of the loading on scapular position and scapulohumeral rhythm. therefore, the evaluation of stabilizer muscles involvement in scapular asymmetry may assist in the development of clinical exa...

holding cash is a matter of managerial discretion. theaim of this paper is to contrast the effect of accruals quality on cashholding for a sample of 120 firms listed in the tehran stock exchangeduring 2001-2011.the results show that firms with good accruals quality hold lower cashlevels than firms with poor accruals quality. this result conform thefindings of teruel & solano (2009), which state...

introduction: analysis of smile is one of the esthetic evaluations in dentistry. in the present study, gla, lid, the long axis position and the oblique axial angle of each tooth were evaluated. materials and methods: in this cross-sectional analytical study, 80 subjects with properly-aligned teeth and healthy periodontium were selected. a digital camera was to take photos of lip areas in unifor...

Much effort has been devoted to the synthesis of gold nanoparticles with different shapes, including the zero-dimensional nanospheres, one dimensional nanorods, and two-dimensional nanoplates. Compared to zero or one dimensional nanostructures, the synthesis of two-dimensional nanostructures in high yield has always been more involved, often requiring complex and timeconsuming steps such as mor...

This paper presents the results of an experimental investigation into collective effects in the transient plasma formed by multiphoton ionization of atomic deuterium with a pulsed laser. The laser wavelength is varied in a narrow range around 243 nm, so that the photoionization is resonant with the metastable 2S(1/2) state. The ion yield, the ion time-of-flight spectra, and the yield of Lyman-a...

the aim of this study is to investigate the relationship between dividend policy with stock liquidity and information asymmetry considering the characteristics of the company as controlling variables in tehran stock exchange. for this purpose, all listed companies in tehran stock exchange as the statistical population was considered during the period 2009 to 2014, that after screening by simple...

the current study aims to review the cross sectional variation in cash flow asymmetric timeliness and its effect on conditional conservatism. in this study, data from 120 firms in tehran stock exchange for the period spanning 1384- 1390 were examined. the regression model used in this research is panel data method with fixed effects approach. the most common measure of conditional conservatism ...
