Noisy One-Way Quantum Computations: The Role of Correlations

A scheme to evaluate computation fidelities within the one-way model is developed and explored to understand the role of correlations in the quality of noisy quantum computations. The formalism is promptly applied to many computation instances, and unveils that a higher amount of entanglement in the noisy resource state does not necessarily imply a better computation.Comment: 10 pages, 6 figures, extension of a previous versio

Maintenance of Gains, Morbidity, and Mortality at 1 Year Following Cardiac Rehabilitation in a Middle‐Income Country: A Wait‐List Control Crossover Trial

Background-—Despite the epidemic of cardiovascular diseases in middle-income countries, few trials are testing the benefits of cardiac rehabilitation (CR). This trial assessed (1) maintenance of functional capacity, risk factor control, knowledge, and hearthealth behaviors and (2) mortality and morbidity at 6 months following CR in a middle-income country. Methods and Results-—Eligible Brazilian coronary patients were initially randomized (1:1:1 concealed) to 1 of 3 parallel arms (comprehensive CR [exercise plus education], exercise-only CR, or wait-list control). The CR programs were 6 months in duration, at which point follow-up assessments were performed. Mortality and morbidity were ascertained from chart and patient or family report (blinded). Controls were then offered CR (crossover). Outcomes were again assessed 6 months later (blinded). ANCOVA was performed for each outcome at 12 months. Overall, 115 (88.5%) patients were randomized, and 62 (53.9%) were retained at 1 year. At 6 months, 23 (58.9%) of those 39 initially randomized to the wait-list control elected to attend CR. Functional capacity, risk factors, knowledge, and heart-health behaviors were maintained from 6 to 12 months in participants from both CR arms (all P>0.05). At 1 year, knowledge was significantly greater with comprehensive CR at either time point (P<0.001). There were 2 deaths. Hospitalizations (P=0.03), nonfatal myocardial infarctions (P=0.04), and percutaneous coronary interventions (P=0.03) were significantly fewer with CR than control at 6 months. Conclusions-—CR participation is associated with lower morbidity, long-term maintenance of functional capacity, risk factors, and heart-health behaviors, as well as with greater cardiovascular knowledge compared with no CR.

O vôo da águia: a decisão popular e a execução pública do orçamento participativo em dourados – MS

No começo da década de 1970, houve uma ascensão dos estudos de cunho político e social acerca da participação, mais relacionadas à interação do indivíduo, o Estado e a teoria da democracia. Qualquer que seja a maneira de manifestação coletiva, haverá um traço comum entre elas, as mesmas são expressões públicas entre os descontentes e as autoridades, na lacuna existente entre política institucional e divergência do interesse coletivo. A participação coletiva em decisões nas administrações públicas apresenta dificuldades, devido à atuação dos agentes políticos, que contrariam as populações, pela condução antidemocrática e corrupção da agenda pública. Este trabalho objetiva-se a priori, analisar a aproximação da sociedade civil ao poder público municipal através do Orçamento Participativo em Dourados-MS, possibilitando à participação na elaboração dos planos de interesses coletivos. A experiência de Dourados-MS é bastante válida, no que se diz respeito ao desenho da gestão pública, sendo amparada nas determinações legais segundo o Estatuto das Cidades, discutindo e aprovando o Plano com participação da sociedade. A peça de planejamento urbano tem características essenciais ao combinar o planejamento, a participação popular, com as diretrizes legais conforme as necessidades estabelecidas.Peer Reviewe
