the purpose of this ex-post facto research is study about relationship between executive function and cognitive distortion on delinquent juveniles and non-delinquent juveniles in tehran. statistical sample are 62 delinquent juveniles selected by purposeful selection from “the center of modification and training” and 82 people of non-delinquent juveniles selected by method of random sampling fro...

Introduction Echo-planar imaging (EPI) is a group of fast data acquisition methods commonly used in fMRI studies. It acquires multiple image lines in k-space after a single excitation, which leads to a very short scan time. A well-known problem with EPI is that it is more sensitive to distortions due to the used encoding scheme. Source of distortion is inhomogeneity in the static B0 field that ...

Introduction: Geometric distortion, an important parameter in neurology and oncology. The current study aimed to design and construct a new three-dimensional (3D) phantom using a 3D printer in order to measure geometric distortion and its 3D reproducibility. Material and Methods: In this study, a new phantom ...

Features in the zero sound attenuation near the pair-breaking edge in superfluid 3He-B have been observed in large magnetic fields. Schopohl and Tewordt [J. Low Temp. Phys. 57, 601 (1984)] claim that the J = 1−,M = ±1 order-parameter collective modes couple to zero sound as a result of the distortion of the equilibrium order parameter by a magnetic field; they identify the new features with the...

The phase diagram of (Tb,, Dyl-,) V04 was studied by crystal optical methods. The low-temperature properties of the mixed crystals are found to depend on the different distorted structures of the pure substances. In (Tb0.4, Dyo.6) VOr, two phase transitions are observed, resulting in a superposition of the two distortion types. DyV04 and TbV04 are well-known examples of a structural phase trans...

We apply a spherical harmonic analysis to the Point Source Redshift Survey (PSCz), to compute the real-space galaxy power spectrum and the degree of redshift distortion caused by peculiar velocities. We employ new parameter eigenvector and hierarchical data compression techniques, allowing a much larger number of harmonic modes to be included, and correspondingly smaller error bars. Using 4644 ...

We propose a three-dimensional holographic reconstruction procedure applicable with no a priori knowledge about the recording conditions enabling distortion-free three-dimensional object reconstruction. This scheme is illustrated through reconstruction of gold nano beads in Brownian motion. OCIS codes: (090.1995) Digital Holography; (070.0070) Fourier Optics; (170.0180) Microscopy Conference Pa...

The title compound α-ammonium iron(III) bis-[hydro-gen arsenate(V)], α-NH4Fe(HAsO4)2 (or poly[ammonium bis-(μ-hydro-gen arsenato)ferrate(III)], {NH4[Fe(HAsO4)2]} n ), syn-the-sized hydro-thermally, is isostructural with NH4Fe(HPO4)2. Condensation of the hydro-gen arsenate groups with FeO6 coordination octa-hedra via common corners results in an overall three-dimensional framework containing int...

This paper examines the impact of …rm heterogeneities on equilibrium pricing behavior in an online market where an information gatekeeper charges click-through fees. As opposed to the assumption of Baye and Morgan (2001) that …rms pay the gatekeeper a …xed fee regardless of the number of clicks they receive, under a click-through regime, a …rm pays a listing fee only if it is clicked. This di¤e...
