Scan-time reduction using noise-matched images in 2- and 3-dimensional bismuth germanate PET/CT : clinical study in head and neck cancer
(2009)We quantitatively and qualitatively investigated 2-dimensional (2D) and 3-dimensional (3D) imaging with scan-time reduction in 14 patients with 17 lesions, who had known or suspected head and neck cancer, using a bismuth ... -
Scanning 6-wavelength 11-channel aerosol lidar
(2000-11)A transportable multiple-wavelength lidar is presented, which is used for the profiling of optical and physical aerosol properties. Two Nd:YAG and two dye lasers in combination with frequency-doubling crystals emit ... -
Scanning diffractometer for the rapid analysis of microparticles and biological cells
(1979-05-01)A laser diffractometer is described which employs a novel scanned array of optical light guides to record the angular intensity variation of light scattered radially by a particle throughout an arc of 180° in approximately ... -
SCATTER: A New Common Envelope Formalism
(2023-02-14)One of the most mysterious astrophysical states is the common envelope (CE) phase of binary evolution, in which two stars are enshrouded by the envelope shed by one of them. Interactions between the stars and the envelope ... -
Scattered broad optical lines in the polarized flux spectrum of the FR II galaxy 3C 321
(1996)The authors present optical/infrared broad-band filter polarimetry and optical spectropolarimetry of the powerful FR II galaxy 3C 321. The latter observations reveal a scattered broad component to the Hα emission line, ... -
Scattering from long prisms : a comparison between ray tracing combined with diffraction on facets and SVM
(University of Bremen, 2003)A new model suitable for rapid computation of scattering on faceted dielectric objects such as ice crystals, which combines ray tracing with diffraction on flat facets, is tested against SVM. Phase functions and asymmetry ... -
Scattering from long prisms using ray tracing combined with diffraction on facets
(2003)A new model suitable for rapid computation of scattering on faceted dielectric objects such as ice crystals is presented. It combines ray tracing with diffraction on flat facets. The model allows retaining the ray nature ... -
Scattering of non-uniform incident fields by long cylinders
(University of Bremen, 2003)We investigate experimentally far-field scattering from cylinders with illumination non-uniform along the axis of the cylinder. Scattered intensity as a function of angle in two orthogonal directions is examined. Variation ... -
Scenario analysis report with policy recommendations: An assessment of sustainability, resilience, efficiency and fairness and effective chain relationships in VALUMICS case studies : Deliverable 8.4
(University of Iceland, 2021-10-15)The functioning of food value chains entails a complex organisation from farm to fork which is characterised by various governance forms and externalities which have shaped the overall food system. VALUMICS food value chain ... -
Scenario Archetypes: Converging Rather than Diverging Themes
(2012-04-20)Future scenarios provide challenging, plausible and relevant stories about how the future could unfold. Urban Futures (UF) research has identified a substantial set (>450) of seemingly disparate scenarios published over ... -
Scenario-Based Meta-Scheduling for Energy-Efficient, Robust and Adaptive Time-Triggered Multi-Core Architectures
(Institute of Electrical and Electronics Engineers (IEEE), 2020-05-18)Complex electronic systems are used in safety-critical applications (e.g., aerospace, nuclear stations), for which the certification standards demand the use of assured design methods and tools. Meta-scheduling is a way ... -
Scenarios of robot-assisted play for children with cognitive and physical disabilities.
(2012)This article presents a novel set of ten play scenarios for robot-assisted play for children with special needs. This set of scenarios is one of the key outcomes of the IROMEC project that investigated how robotic toys can ... -
Schistosome cercarial interactions with human keratinocytes and langerhans cells
(2006-08)The human parasite, Schistosoma mansoni is known to modulate host immune responses in order to promote its own survival. However, studies investigating the interaction between the skin-invading cercarial stage and cells ... -
Schizophrenia is associated with dysregulation of a Cdk5 activator that regulates synaptic protein expression and cognition
(2011-08)Cyclin-dependent kinase 5 is activated by small subunits, of which p35 is the most abundant. The functions of cyclin-dependent kinase 5 signalling in cognition and cognitive disorders remains unclear. Here, we show that ... -
Schizophrenia: helping patients adhere to long-term management plans
(2010-04)Schizophrenia affects around one in every 100 people during their lifetime. First symptoms are typically experienced between the ages of 15 and 35, and the disease affects men and women equally. Incidence is higher in ... -
The School Attachment Monitor—A novel computational tool for assessment of attachment in middle childhood
(2021-07-22)Background Attachment research has been limited by the lack of quick and easy measures. We report development and validation of the School Attachment Monitor (SAM), a novel measure for largescale assessment of attachment ...
