In this article, we investigate the interference alignment (IA) solution for a K-user MIMO interference channel. Proper users’ precoders and decoders are designed through a desired signal power maximization model with IA conditions as constraints, which forms a complex matrix optimization problem. We propose two low complexity algorithms, both of which apply the Courant penalty function techniq...

Objective: To compare the prognosis estimated by standard prognostic criteria versus the prognosis estimated by the Oncotype DX. Methods: A retrospective study was performed on 22 patients with positive estrogen receptor, early-stage breast cancer who had an Oncotype DX recurrence score available. Results: Kappa value between Oncotype DX and standard prognostic criteria was: Adjuvant! (K = 0.09...

The paper reports on experiments with acoustic recordings of a self-built replica of the historic speaking machine of Wolfgang von Kempelen. Several possibilities of the reed as the glottal excitation mechanism were tested. Perception tests with naïve listeners revealed that the machinegenerated words 'mama' and 'papa' were partially recognised as an authentic child voice – as it was also the c...

BACKGROUND Few women in Uganda access intermittent preventive treatment of malaria in pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP). Previous studies have shown that high costs, frequent stock-out of drugs, supplies and poor quality of care are the greatest hindrance for women to access health services. In order to increase adherence to IPTp, we conceptualised an intervention that offset...

The aim of this study was to investigate the resistance to quinolones and tetracycline of 200 C. jejuni and C. coli strains isolated from poultry and poultry meat. Among the strains tested, a high-level of resistance, ranging from 78% to 82% for nalidixid acid and ciprofloxacin, as well as from 44%-56% for tetracycline was observed. Moreover, all Campylobacter strains were examined for the mole...

ated in each group, TST and SST Z-scores of HBeAg-positive patients were significantly higher than those in anti-HBe positive patients in group 1 ( p < 0.05). No statistically significant differences were observed in the other Z-scores ( p > 0.05). When HBeAg-positive patients and antiHBe-positive patients were compared in group 2, TST, SST, MAC, and MAMA Z-scores were not found to be statistic...

Two hundred seventy-seven position angle and separation measures of 154 double stars are presented. Three of the systems were previously unknown to be double, and 16 other systems were discovered earlier this decade by the Hipparcos satellite. Measures are derived from speckle observations taken with the Wisconsin-Indiana-Yale-NOAO (WIYN) 3.5 m telescope located at Kitt Peak, Arizona. Speckle i...

Superparamagnetic iron oxide nanoparticles (SPIO NPs) have a wide range of biomedical applications such as in magnetic resonance imaging, targeting, and hyperthermia therapy. Aggregation of SPIO NPs can occur because of the hydrophobic surface and high surface energy of SPIO NPs. Here, we developed a facile method to encapsulate SPIO NPs in amphiphilic biodegradable polymer. Anionic biodegradab...

O câncer foi, por muito tempo, considerado um problema de saúde em países desen volvidos. Segundo levantamento de dados atuais e perspectivas futuras, os países em desen volvimento concentram agora a maior parte da população mundial com a doença. No entanto, os sistemas de saúde nessas áreas são reconhecidamente mal estruturados para absorver esse problema emergente. O aumento progressivo na pr...
