BACKGROUND: Associations of higher indoor carbon dioxide (CO2) concentrations with impaired work performance, increased health symptoms, and poorer perceived air quality have been attributed to correlation of indoor CO2 with concentrations of other indoor air pollutants that are also influenced by rates of outdoor-air ventilation. OBJECTIVES: We assessed direct effects of increased CO2, within the range of indoor concentrations, on decision making. METHODS: Twenty-two participants were exposed to CO2 at 600, 1,000, and 2,500 ppm in an office-like chamber, in six groups. Each group was exposed

Real-world networks are often claimed to be scale free, meaning that the fraction of nodes with degree k follows a power law k-α, a pattern with broad implications for the structure and dynamics of complex systems. However, the universality of scale-free networks remains controversial. Here, we organize different definitions of scale-free networks and construct a severe test of their empirical prevalence using state-of-the-art statistical tools applied to nearly 1000 social, biological, technological, transportation, and information networks. Across these networks, we find robust evidence that

Here, we organize different definitions of scale-free networks and construct a severe test of their empirical prevalence using state-of-the-art statistical tools applied to nearly 1000 social, biological, technological, transportation, and information networks. Across these networks, we find robust evidence that strongly scale-free structure is empirically rare, while for most networks, log-normal distributions fit the data as well or be

BACKGROUND: Viability staining with SYTO9 and propidium iodide (PI) is a frequently used tool in microbiological studies. However, data generated by such routinely used method are often not critically evaluated for their accuracy. In this study we aim to investigate the critical aspects of this staining method using Staphylococcus aureus and Pseudomonas aeruginosa as the model microorganisms for high throughput studies in microtiter plates. SYTO9 or PI was added alone or consecutively together to cells and the fluorescence intensities were measured using microplate reader and confocal laser sc

BACKGROUND: Students in need of mental health care face many barriers including cost, location, availability, and stigma. Studies show that computer-assisted therapy and 1 conversational chatbot delivering cognitive behavioral therapy (CBT) offer a less-intensive and more cost-effective alternative for treating depression and anxiety. Although CBT is one of the most effective treatment methods, applying an integrative approach has been linked to equally effective posttreatment improvement.
