Researchers at Penn State have created innovative design methods for a new class of antennas composed of fractal-shaped tiles, offering improved bandwidth and radiation patterns. The fractile arrays are generated recursively and offer advantages over conventional square boundaries.
A study by Dr. Emilie Phillips Smith found that family, school, and community factors play a significant role in shaping children's racial-ethnic attitudes and academic achievement. The research used interviews and questionnaires to assess the attitudes of African American child and parent pairs in South Carolina.
Researchers studied 99 adults with mild hypertension, finding reduced heart function during exercise and at rest if they delivered less oxygen per beat. This study suggests oxygen pulse during exercise could be a useful screening tool for identifying heart issues in these individuals.
Cystic fibrosis patients with inhaled antibiotics show improved lung function and reduced bacterial growth. Effective antibiotic therapy is essential for managing CF lung disease.
A study found that teenagers face challenges in accessing relevant health information online, with common barriers including poorly designed websites, lack of targeted content, and ineffective search strategies. To improve access, researchers suggest teaching better search skills and designing websites more tailored to users' needs.
A study analyzing data from 2,016 congregation members found that altruistic actions are associated with improved mental health. People who give help to others may be less likely to focus on their own anxieties and depression, leading to better mental well-being.
A study by Joslin Diabetes Center shows that care ambassadors can significantly improve blood sugar levels and reduce complications in children with type 1 diabetes. The program helps families establish patterns of lifelong diabetes management, leading to fewer hospitalizations and emergency room visits.
A study of 83 heart attack patients found that 12% did not exercise at all over the next year, despite completing a cardiac rehabilitation program. The number of people exercising decreased significantly, with most sessions lasting only 35-45 minutes and averaging only 28.2% time spent in the targeted heart rate zone.
Nitric oxide inhibits endothelial cell release of inflammatory substances by targeting a specific protein, thereby regulating exocytosis and preventing inflammation. Researchers have developed a novel drug that blocks this process, showing promise as an anti-clotting agent for various diseases.
