The aim of this study was to compare mean glandular dose (MGD) in all full-field digital mammography (FFDM) and screen film mammography (SFM) systems used in a national mammography screening program. MGD from 31 screening units (7 FFDM and 24 SFM), based on an average of 50 women at each screening unit, representing 12 X-ray models (6 FFDM and 6 SFM) from five different manufacturers were calcu...

Remotely sensing recent growth, herbivory, or disturbance of herbaceous and woody vegetation in dryland ecosystems requires high spatial resolution and multi-temporal depth. Three dimensional (3D) remote sensing technologies like lidar, and techniques like structure from motion (SfM) photogrammetry, each have strengths and weaknesses at detecting vegetation volume and extent, given the instrume...

Kurzfassung. Das Active Shape Model (ASM) ist ein Segmentierungsverfahren, das statistische Formmodelle (SFM) verwendet, um Organe in Bilddaten trotz geringen Kontrastes zu benachbarten Strukturen robust und effizient zu segmentieren. Da das ASM ein lokales Suchverfahren ist, muss vor der Segmentierung zunächst das gesuchte Organ im Bild detektiert werden, um dann das SFM initial möglichst gena...

The last two decades of forest policy discussions have been dominated by calls for sustainable management of forest resources. Consequently, multiple international and domestic policies, supporting sustainable forest management (SFM), have evolved in numerous jurisdictions. Policies in developing countries often rely on foreign donors’ projects, which supplement domestic SFM policy. These polic...

Matrix factorization in the presence of missing data is at the core of many computer vision problems such as structure from motion (SfM), non-rigid SfM and photometric stereo. We formulate the problem of matrix factorization with missing data as a low-rank semidefinite program (LRSDP) with the advantage that: 1) an efficient quasi-Newton implementation of the LRSDP enables us to solve large-sca...

It would be of great value when available databases of screen-film mammography (SFM) images can be used to train full-field digital mammography (FFDM) computer-aided detection (CAD) systems, as compilation of new databases is costly. In this paper, we investigate this possibility. Firstly, we develop a method that converts an FFDM image into an SFM-like representation. In this conversion method...

Attaining high quality from manufacturing systems requires utilizing appropriate system-level quality performance modeling and analysis tools. This paper describes the application of the stochastic-flow-modeling (SFM) approach to represent the quality output behavior of a manufacturing system. To do this, a basic one-product type SFM is extended to that of a multiple-product manufacturing syste...

Saframycin A (SFM-A), produced by Streptomyces lavendulae NRRL 11002, belongs to the tetrahydroisoquinoline family of antibiotics, and its core is structurally similar to the core of ecteinascidin 743, which is a highly potent antitumor drug isolated from a marine tunicate. In this study, the biosynthetic gene cluster for SFM-A was cloned and localized to a 62-kb contiguous DNA region. Sequence...

Our objective was to determine the standardized ileal digestibility (SID) of CP and AA in soybean meal (SBM) and canola, cotton, and sunflower products fed to finishing pigs. Each of 8 barrows (average initial BW = 106.6 ± 5.5 kg) were surgically fitted with a T-cannula in the distal ileum. Pigs were allotted to an 8 × 8 Latin square design with 8 diets and 8 periods. The 7 protein ingredients ...

We compared three-dimensional structure-from-motion (3D-SFM) processing in awake monkeys and humans using functional magnetic resonance imaging. Occipital and midlevel extrastriate visual areas showed similar activation by 3D-SFM stimuli in both species. In contrast, intraparietal areas showed significant 3D-SFM activation in humans but not in monkeys. This suggests that human intraparietal cor...
