Study-level meta-analyses of ABM have produced conflicting findings and leave critical questions unresolved regarding ABM's mechanisms of action and clinical potential. We pooled patient-level datasets from randomized controlled trials of children and adults with high-anxiety. Attentional bias (AB) towards threat, the target mechanism of ABM, was tested as an outcome and a mechanistic mediator and moderator of anxiety reduction. Diagnostic remission and Liebowitz Social Anxiety Scale (LSAS) were clinical outcomes available in enough studies to enable pooling. Per-patient data were obtained on at least one outcome from 13/16 eligible studies [86% of eligible participants; n=778]. Significant main effects of ABM on diagnostic remission (ABM-22.6%, control-10.8%; OR=2.57; p=0.006) and AB (β* (95%CI)=-0.63 (-0.83, -0.42); p<0.00005) were observed. There was no main...

For this investigation we prepared a tungsten substitution on the barium hexaferrite Ba0.5W0.5Fe12O19 using sol–gel self-combustion technology. The powder was treated for 30 min, without atmosphere precautions, at 850 �C, 900 �C, 950 �C, 1000 �C and 1050 �C. Scanning electron microscopy has revealed the crystallite size and shape, and the X-ray diffraction was provided information related to the phase compositions. The investigation was focused on the variation of permittivity and electrical resistivity, in relation to the treatment temperature, frequency and humidity. We have also investigated the influence of thermal treatment on to Curie temperature and frequency characteristics of the relative permeability. Because barium–tungsten ferrite shows a porous structure, the measurements are strongly influen...
