In the first part, we determine conditions on spectra X and Y under which either every map from X to Y is phantom, or no nonzero maps are. We also address the question of whether such all or nothing behaviour is preserved when X is replaced with V ∧ X for V finite. In the second part, we introduce chromatic phantom maps. A map is n-phantom if it is null when restricted to finite spectra of type...

OBJECTIVE Patients who misperceive that they are moving their paralysed arm (phantom movements) may not recognise its weakness. Therefore, the relation between phantom limb movements and anosognosia for hemiplegia during selective right hemispheric anaesthesia (the Wada test) was examined. METHODS Nine patients with intractable epilepsy underwent the Wada test. During the right hemispheric in...

We determined the crystal structure of ${\mathrm{Cs}}_{2}{\mathrm{LiRuCl}}_{6}$, which was synthesized in this work, and investigated its magnetic properties. ${\mathrm{Cs}}_{2}{\mathrm{LiRuCl}}_{6}$ has a hexagonal composed linear chains face-sharing ${\mathrm{RuCl}}_{6}$ ${\mathrm{LiCl}}_{6}$ octahedra. In two thirds structural chains, ${\mathrm{Ru}}^{3+}$ ${\mathrm{Li}}^{+}$ sites are almost...

We investigated the appropriateness of four different mammography phantoms for image quality evaluation in Digital Breast Tomosynthesis (DBT). We tested the CIRS BR3D phantom, the ACR Prototype FFDM Accreditation Phantom, the Penn anthropomorphic breast phantom and the Quart mam/digi EPQC phantom. This work discusses the advantages and shortcomings of each phantom and concludes that none of the...

Abstract a low-profile modified elliptical structure ultra-wide-band monopole antenna for skin cancer detection is presented in this paper. The developed over an FR-4 lossy substrate with permittivity 4.3 and height of 1.6 mm. dimensions 20 × 28 mm 3 it covers frequency range 2.82-12.56 GHz. proposed consists circular shaped radiators partial ground plane, to achieve optimized low profile ultra...

Echo-planar spectroscopic imaging (EPSI) can be used for fast spectroscopic imaging of water and fat resonances at high resolution to improve structural and functional imaging. Because of the use of oscillating gradients during the free induction decay (FID), spectra obtained with EPSI are often degraded by Nyquist ghost artifacts arising from the inconsistency between the odd and even echoes. ...

OBJECTIVE To provide a better understanding of the prevalence, correlates and quality of phantom sensations and phantom pain in child and adolescent amputees. DESIGN Retrospective survey study. SETTING Recruitment through the War Amputations of Canada. PARTICIPANTS Sixty child and adolescent amputees aged 8-18 years who were missing a limb due to a congenital limb deficiency (n = 27) or s...
