The transition from conventional screen-film radiography (SFR) to computed radiography (CR) or digital radiography (DR) can involve an increase in patient radiation doses due to the wide dynamic range of the digital imaging systems, which allows overexposure with no adverse effect on image quality. The current study intends to measure and compare the radiation dose to adult patients during (i) ...
Many genomes are incorrectly identified at GenBank. We developed a plan to find and correct misidentified genomes using genomic comparison statistics together with a scaffold of reliably identified genomes from type. A workshop was organized with broad representation from the bacterial taxonomic community to review the proposal, the GenBank Microbial Genomic Taxonomy Workshop, Bethesda MD, May ...
The first official day of the conference, 14 May, opened with parallel sessions held in no less than 7 rooms, on acute stroke, stroke and infections, risk factors and their management, and ditto for diabetes. These sessions were finished in time for general attendance at the highlights of the meeting. First, after an elegant introduction by J. van Gijn, M.G. Bousser, the Johann Jacob Wepfer awa...
In this paper a ring of calibrated and synchronized cameras is used for achieving robot and obstacle localization inside a common observed area. To avoid complex appearance matching derived from the wide-baseline arrangement of cameras, a metric occupancy grid is obtained by intersection of silhouettes projected onto the floor. A particle filter is proposed for tracking multiple objects by usin...

نیتروین-13 یک رادیوایزوتوپ پوزیترون دهنده با نیمه عمر 10 دقیقه از اعضای خانواده ی pet استاندارد است. یکی از وییگیهای این رادیوایزوتوپ این است که امکان آزمایشهای مکرر را بر روی موجود زنده ممکن می سازد. نیتروین-13 معمولا به شکل آمونیاک نشاندارشده با نیتروین-13 مورد استفاده قرار می گیرد. یکی از روشهای مناسب برای تولید آمونیاک پرتودهی پروتون به آب خالص توسط شتابدهنده ی سیکلوترون است. به این معنی که...
implicit and unobserved errors and vulnerabilities issues usually arise in cryptographic protocols and especially in authentication protocols. this may enable an attacker to make serious damages to the desired system, such as having the access to or changing secret documents, interfering in bank transactions, having access to users’ accounts, or may be having the control all over the syste...
• Cardiac MRI must assess morphology, function, blood supply, and tissue status • Cardiac MRI scans must be gated to the heart cycle • Gated scans also typically require some form of respiratory correction • Morphology and function are often assessed simultaneously with a cine scan • Blood supply to the heart is assessed by monitoring the passage of contrast agent through the myocardium • Myoca...
Let H and G be graph classes. We say that H has the Erdős-Pósa property for G if for any graph G ∈ G, the minimum vertex covering of all H-subgraphs of G is bounded by a function f of the maximum packing of H-subgraphs in G (by H-subgraph of G we mean any subgraph of G that belongs to H). In his monograph “Graph Theory”, R. Diestel proves that if H is the class of all graphs that can be contrac...
