Adaptive Modulation and Coding (AMC) is combined with Multiple Input Multiple Output (MIMO) multiplexing to improve the throughput performance of AMC. In addition, Selection Transmit Diversity (STD) is considered in MIMO multiplexing to achieve higher diversity gain. AMC-STD-MIMO multiplexing system is proposed. STD in our simulation selects 2 transmission antennas from 4 antennas and AMC-MIMO ...

Mandibular hypomobility results from various disorders affecting the stomatognathic system. Arthrogryposis multiplex congenita (AMC) is an uncommon systemic disorder with mandibular hypomobility involved. Notably few cases of AMC with limited mouth opening and reduced range of jaw movement have been described in which this restriction has been attributed to involvement of the coronoid process. ...

Although the proteasome plays a critical role in the controlled degradation of proteins involved in cell cycle control, the direct modulation of proteasomal function by growth regulatory signaling has not yet been demonstrated. We assessed the effect of transforming growth factor (TGF)-beta, a potent inhibitor of cell growth, on proteasomal function. TGF-beta selectively decreased hydrolysis of...

BACKGROUND To evaluate the knowledge, attitudes and beliefs about adult male circumcision (AMC), assess the association of AMC with HIV incidence and prevalence, and estimate AMC uptake in a Southern African community. METHODS A cross-sectional biomedical survey (ANRS-12126) conducted in 2007-2008 among a random sample of 1198 men aged 15 to 49 from Orange Farm (South Africa). Face-to-face in...

The current research aims to further investigate the application of Automated Machine Control/Guidance (AMC/G) in construction projects and proposes an integrated approach for: (1) Improving the administrative infrastructure required for the optimal application of AMC/G; and (2) Orchestrating the machine-level AMC/G technologies into a coherent project-level system committed to the coordination...

BACKGROUND The prognostic significance of the circulating absolute monocyte count (AMC) in patients with locally advanced hepatocellular carcinoma (HCC) is uncertain. This study was designed to assess the association of circulating AMC with survival outcomes in patients diagnosed with locally advanced or metastatic HCC receiving systemic chemotherapy. MATERIALS AND METHODS Between January 1, ...

Although LTE-Advanced system is targeted at enhancing the users’ throughput and increasing connection reliability, however user’s mobility tends to degrade the efficiency of the services and applications in terms of throughput degradation and outage probability reduction. Particularly this is during the handover from the source to the target eNBs. Therefore, the Carrier Aggregation (CA) techniq...

Affinity monolith chromatography (AMC) is a type of liquid chromatography that uses a monolithic support and a biologically related binding agent as a stationary phase. AMC is a powerful method for the selective separation, analysis, or study of specific target compounds in a sample. This review discusses the basic principles of AMC and recent developments and applications of this method, with ...

In this paper, we propose a Double-Space Time Transmit Diversity (D-STTD) communication system with Adaptive Modulation and Coding (AMC) scheme and analyze its performance using simulation experiments. The simulation results show that the probability of selecting a high Modulation and Coding Scheme (MCS) level increased as the Signal to Noise Ratio (SNR) improved. Furthermore, the D-STTD commun...

Background: We have reported that arterial micro-calcification (AMC) of vascular access has a negative impact on access patency and cardiovascular mortality in hemodialysis (HD) patients. Because AMC is diagnosed by histologic examination, it cannot be commonly performed. Coronary artery calcification (CAC) is quite common and known risk factors of cardiovascular mortality in HD patients. It ca...
