BACKGROUND There is little consensus on how many hours of accelerometer wear time is needed to reflect a usual day. This study identifies the bias in daily physical activity (PA) estimates caused by accelerometer wear time. METHODS 124 adults (age = 41 ± 11 years; BMI = 27 ± 7 kg·m⁻²) contributed approximately 1,200 days accelerometer wear time. Five 40 day samples were randomly selected with...

Cells must coordinate adjustments in genome expression to accommodate changes in their environment. We hypothesized that the amount of transcriptome change is proportional to the amount of environmental change. To capture the effects of environmental changes on the transcriptome, we compared transcriptome diversities (defined as the Shannon entropy of frequency distribution) of silkworm fat-bod...

In this study, Ti6Al4V (Grade 5) alloys were first dissoluted at 850?C for 120 min. and then aged 250?C, 350?C, 450?C, 550?C, 650?C 750?C respectively. After each aging duration (by looking hardness ratios between 9 to 54 hours), the of samples was measured. Depending on temperature time increase, increased upon formation ?' phases. phases, started decrease. The highest value measured in sample...
