A simple solution to mixing problems in micro fluidic systems was presented in this paper. A T-form microfluidic mixer was designed and tested utilizing pressure disturbances. The performance of the mixer was studied through both numerical simulation and experimentation. Based on results of numerical simulation, more than 75% mixing can be finished within a mixing distance of less than 1.5mm fr...

Regulatory T (Treg) cells are essential for normal immune surveillance systems, and their dysfunction leads to development of diseases, such as autoimmune disorders. CD4(+)CD25(+) Treg cells are well-known suppressive cells, which express the transcription factor Foxp3, are indispensable for the maintenance of immune self-tolerance and homeostasis by suppressing aberrant or excessive immune res...

This paper deals with a new Bayesian approach to the one-sample test for proportion. More specifically, let x=(x1,…,xn) be an independent random sample of size n from Bernoulli distribution unknown parameter θ. For fixed value θ0, goal is null hypothesis H0:θ=θ0 against all possible alternatives. The proposed based on using well-known formula Kullback–Leibler divergence between two binomial dis...

OBJECTIVE To provide a practical guidance for the analysis of N-of-1 trials by comparing four commonly used models. METHODS The four models, paired t-test, mixed effects model of difference, mixed effects model and meta-analysis of summary data were compared using a simulation study. The assumed 3-cycles and 4-cycles N-of-1 trials were set with sample sizes of 1, 3, 5, 10, 20 and 30 respectiv...

The Kids and Communities Count Farm Safety Lesson is a follow-up to our Kids Count Lesson that used the North American Guidelines for Children's Agricultural Tasks (NAGCAT) and was previously delivered to nearly 2,000 fifth-grade students in Hillsborough County, Florida. This year, the lesson was administered in two migrant schools and included a parent survey and a presentation of the lesson i...
