In this report, we describe three encodings of the multiple constant multiplication (MCM) problem to pseudo-boolean satisfiability (PBS), and introduce an algorithm to solve the MCM problem optimally. To the best of our knowledge, the proposed encodings and the optimization algorithm are the first formalization of the MCM problem in a PBS manner. This report evaluates the complexity of the prob...

In this paper a demonstrator oscillator circuit integrated in a MCM-D on glass technology is presented. The active device of the oscillator is a thin-film Ge (germanium) -based MHEMT. The MHEMT is embedded in the bottom dielectric layer of the MCM-D. The combination of passive MCM-D technology and MHEMTs on Ge allows for efficient semi-monolithic integration of active devices and realisation of...

INTRODUCTION Synovial macrophages, which can release proinflammatory factors, are responsible for the upregulation of cartilage-breakdown proteases and play critical roles in cartilage degradation during the progression of osteoarthritis (OA). In addition, shear stress exerts multifunctional effects on chondrocytes by inducing the synthesis of catabolic or anabolic genes. However, the interplay...

chemical vapor deposition was employed to synthesize carbon nanotubes with ni-loaded mcm-41 and mcm-48 as catalysts and acetylene as precursor at 750°c. mesoporous ni mcm-41 and ni mcm-48 molecular sieves were synthesized by a hydrothermal method and were characterized by xrd and n2 adsorption isotherm. the catalytically synthesized carbon materials were characterized with raman spectroscopy, n...

Prostate cancer is one of the most frequent cancers among men in the United States. In the current study, we examined the susceptibility of the human LNCaP prostate cancer cells to the apoptotic effect of marina crystal minerals (MCM), a crystallized mixture of minerals and trace elements from sea water, in vitro. Cancer cells were cultured with MCM at different concentrations (0-1000 microg/ml...

The catalytic performance of incorporated V-MCM-41 catalysts for the partial direct oxidation of methane to formaldehyde with molecular oxygen has been investigated. V-MCM-41 catalysts containing 0.56–1.86 wt.% V have been prepared by incorporating the vanadium ions into the framework of mesoporous siliceous MCM-41, resulting in a highly ordered structure with large BET surface area and high su...

BACKGROUND Minichromosome maintenance proteins (MCM), due to their involvement in DNA replication in the course of mitosis, may provide sensitive markers of cell proliferation. Localization of MCM-3 and the extent of its expression were evaluated in mammary adenocarcinomas and soft tissue fibrosarcomas in dogs. The obtained results were compared to grades of malignancy (G) of the studied tumour...

In eukaryotic cells, MCM, the minichromosome maintenance proteins, form a heterohexamer during G(1) phase in the cell cycle and constitute a DNA helicase activity at the onset of replication. MCM proteins are downregulated and dissociated from chromatin when cells exit the cell cycle. MCM proteins are upregulated frequently in a variety of dysplastic and cancer cells. To delineate the role of M...
