Maximum margin principle has been successfully applied to many supervised and semi-supervised problems in machine learning. Recently, this principle was extended for clustering, referred to as Maximum Margin Clustering (MMC) and achieved promising performance in recent studies. To avoid the problem of local minima, MMC can be solved globally via convex semi-definite programming (SDP) relaxation...

Background: The aim of this study was to assess the changes in plasma levels of antioxidant enzymes and melano-macrophage centers (MMCs) in immune tissues as biomarkers of yellowfin seabream (Acanthopagrus latus) exposed to phenanthrene (Phe) for 14 days. Methods: The research was carried out at Khorramshahr University of Marine Science and Technology, Khorramshahr, Iran in Jan 2016. Thirty-si...

Silver chloride containing particles of irregular form of the order of 1 ktm in diameter is used as a model material for particle-reinforced metal matrix composites (MMCs). Matrix dislocations due to the mismatch of the coefficients of thermal expansion of the two phases are made visible to transmission optical microscopy through bulk decoration performed at room temperature. The plastic zone a...

The interdigestive antroduodenal motor activity was studied in 15 patients with bile reflux without gastritis (group A), 17 with bile reflux and chronic antral superficial gastritis (group B) and in nine healthy controls (group C), by manometric recording of phases of the interdigestive motility complex (IDMC) over 240 minutes, or until two consecutive migrating motor complexes (MMCs) had been ...

Submodule (SM) capacitor voltage ripples in modular multilevel converters (MMCs) can be suppressed by harmonic injection strategy, which reduce the volume and cost of MMCs. The existing methods using dual strategy for hybrid MMCs only consider steady-state conditions. Harmonic strategies unbalanced grid conditions use single applied single-phase faults. To address above issues, this paper propo...

Aluminium—boron carbide metal matrix composites (Al-B4C MMCs) belong to the class of materials extensively used in nuclear industry as a thermal neutron absorber spent fuel casks. This article investigates novel production method Al-B4C MMCs—Friction Stir Additive Processing (FSAP)—as an alternative casting or sintering. FSAP is derived from friction stir welding, which can be local modificatio...

We previously showed that atRA (all-trans Retinoic Acid, atRA) inhibites chondrogenesis by downregulation of TGF-beta/Smad signaling. However, the molecular link between RA and TGF-beta signaling is unknown. Using a mouse embryo palate mesenchyme micomass cultures (MMCs) system, we explored interactions of RA and TGF-beta signaling during chondrogenesis. We found that atRA suppressed chondrogen...

To determine the effects of glucose on insulin-like growth factor I (IGF-I)-induced mesangial cell (MC) proliferation, we have examined the relationships between IGF binding protein 2 (IGFBP-2) secretion and proliferation in murine MCs (MMCs). MMCs incubated in high glucose (HG, 25 mM) exhibited a 25-30% reduction in IGFBP-2 secretion compared with cells in normal glucose (NG, 5.6 mM). This los...
