To solve the degradation of the BER performance of Space-Time Block Code (STBC)/MC-CDMA system when MC-CDMA system has large number of users, we propose Unitary Space-Time Modulation (USTM)/MC-CDMA system. USTM combines STBC and baseband modulation by employing unitary matrix. USTM is designed in order not to receive signals from different transmit antennas simultaneously at the receiver. In th...

Tryptase, a 135kDa tetrameric serine protease, was originally isolated from lung mast cells (MC). This enzyme is stored in and released from MC granules upon activation. Tryptase is an exquisite marker in heterogeneous populations of MC, allowing for their differentiation from basophils. Because tryptase is the principal protein mediator component of mast cell granules, accounting for 23% of th...

OBJECTIVES Methylcellulose (MC) is a chemical compound derived from cellulose. MTA mixed with MC reduces setting time and increases plasticity. This study assessed the influence of MC as an anti-washout ingredient and CaCl2 as a setting time accelerator on the physical and biological properties of MTA. MATERIAL AND METHODS Test materials were divided into 3 groups; Group 1(control): distilled...

BACKGROUND Maputo, the Mozambique capital, contrasts with the rest of the country with regard to its sociodemographic characteristics and patterns of tobacco exposure. We conducted a migrant study to compare the prevalence of manufactured-cigarette smoking and traditional forms of tobacco use among dwellers in the capital who were also born in Maputo City (MC/MC) with those born in southern (SP...

Inflorescence development is a key factor of plant productivity, as it determines flower number. Therefore, understanding the mechanisms that regulate inflorescence architecture is critical for reproductive success and crop yield. In this study, a new mutant, vegetative inflorescence (mc-vin), was isolated from the screening of a tomato (Solanum lycopersicum L.) T-DNA mutant collection. The mc-...

Mitomycin C induces both MC-mono-dG and cross-linked dG-adducts in vivo. Interstrand cross-linked (ICL) dG-MC-dG-DNA adducts can prevent strand separation. In Escherichia coli cells, UvrABC repairs ICL lesions that cause DNA bending. The mechanisms and consequences of NER of ICL dG-MC-dG lesions that do not induce DNA bending remain unclear. Using DNA fragments containing a MC-mono-dG or an ICL...

Highly stable sulfur/microporous carbon (S/MC) composites are prepared by vacuum infusion of sulfur vapor into microporous carbon at 600 °C, and lithium sulfide/microporous carbon (Li2S/MC) cathodes are fabricated via a novel and facile in situ lithiation strategy, i.e., spraying commercial stabilized lithium metal powder (SLMP) onto a prepared S/MC film cathode prior to the routine compressing...

Mitomycin C (MC) activation to a reactive species was studied in nuclei isolated from rat liver and EMT6 tumor cells. Both preparations were similar in the rate of 4-(p-nitrobenzyl)pyridine (NBP) alkylation by MC and the levels of NADPH-cytochrome P-450 reductase. MC activation by both hepatic and EMT6 cell nuclei was inhibited by the presence of O2 and by heat inactivation. NADPH was preferred...

Monte Carlo (MC) is rarely used for IMRT plan optimization outside of research centres due to the extensive computational resources or long computation times required to complete the process. Time can be reduced by degrading the statistical precision of the MC dose calculation used within the optimization loop. However, this eventually introduces optimization convergence errors (OCEs). This stu...
