Healthy aging is associated with brain volume reductions that involve the frontal cortex, but also affect other brain regions. We sought to identify an age-related network pattern of MRI gray matter using a multivariate statistical model of regional covariance, the Scaled Subprofile Model (SSM) with voxel based morphometry (VBM) in 29 healthy adults, 23-84 years of age (Group 1). In addition, w...

The intermolecular interactions in concentrated solutions of pig submaxillary mucin (PSM) and sheep submaxillary mucin (SSM) were studied by mechanical spectroscopy. PSM and SSM were purified from detectable protein and nucleic acid by equilibrium centrifugation in a CsCl density gradient. PSM and SSM isolated in the presence of proteinase inhibitors showed distinct differences from preparation...

Abstract. The current intensive use of agricultural land is affecting the quality and contributes to climate change. Feeding world's growing population under changing climatic conditions demands a global transition more sustainable systems. This requires efficient models data monitor cultivation practices at field scale. study outlines spatially distributed version field-scale crop model AquaCr...

Soft systems methodology (SSM) is a well-known Problem Structuring Methods that has proven effective when tackling problematic situations. To model different perceptions of situation, SSM encourage stakeholders to propose possible transformation likely improve the situation. The more transformations compiled richer process become; but in practice, managing higher number presents challenge. Valu...

Construction projects are faced with a challenge that must not be underestimated. These projects are increasingly becoming highly competitive, more complex, and difficult to manage. They become ‘wicked problems’, which are difficult to solve using traditional approaches. Soft Systems Methodology (SSM) is a systems approach that is used for analysis and problem solving in such complex and messy ...

Semisolid metal (SSM) processing or thixoforming is widely known as a technology that involves the formation of metal alloys between solidus and liquidus temperatures. For the procedure to operate successfully, the microstructure of the starting material must consist of solid near-globular grains surrounded by a liquid matrix and a wide solidus-to-liquidus transition area. Currently, this proce...

The asymmetries Ak ≡ [Γ(t → Wdk)−Γ(t̄ → Wd̄k)]/[Γ(t → Wdk)+Γ(t̄ → Wd̄k)] in the partial widths of the top quark decays are discussed within the Standard Model (SM), the Two-Higgs-Doublet Model (2HDM) and supersymmetric extensions of the SM (SSM). The leading contributions to these asymmetries in the SM and in the 2HDM are induced by the up-type quark self-energy diagrams and are found to be very sm...

Many inference methods have been proposed to reconstruct unknown Gene Regulatory Networks (GRN) using microarray datasets. State Space Model (SSM) is a method that can be used to infer GRNs from a time series dataset. However, there exist two difficulties in SSM when it is applied for GRN reconstruction: how to estimate initial values of parameters and how to learn the genegene interactions in ...

BACKGROUND Axillary lymph node (AN) status is the primary prognostic discriminant in patients with breast cancer (BC). Although axillary dissection represents the method of choice for obtaining such information, less invasive procedures have been suggested. The aim of this study was to evaluate the usefulness of 99mTc-sestamibi scintimammography (SSM) in detecting AN involvement in patients wit...

To support the operational use of Synthetic Aperture Radar (SAR) earth observation systems, the European Space Agency (ESA) is developing Sentinel-1 radar satellites operating in C-band. Much like its SAR predecessors (Earth Resource Satellite, ENVISAT, and RADARSAT), the Sentinel-1 will operate at a medium spatial resolution (ranging from 5 to 40 m), but with a greatly improved revisit period,...
