Recent studies of mammalian transcriptomes have identified numerous RNA transcripts that do not code for proteins; their identity, however, is largely unknown. Here we explore an approach based on sequence randomness patterns to discern different RNA classes. The relative z-score we use helps identify the known ncRNA class from the genome, intergene and intron classes. This leads us to a fracti...
OBJECTIVE To investigate associations of family-related factors with children's breakfast consumption and BMI-z-score and to examine whether children's breakfast consumption mediates associations between family-related factors and children's BMI-z-score. SUBJECTS Ten- to twelve-year-old children (n = 6374; mean age = 11.6 ± 0.7 years, 53.2% girls, mean BMI-z-score = 0.4 ± 1.2) and one of thei...
BACKGROUND Inappropriate feeding practices during infancy may lead to overweight. The aims of this study are to investigate the growth of children in the first 18 months of life; to evaluate the feeding practices of caregivers using developed Young Child Feeding Questionnaire; and to investigate caregivers' feeding attitudes and behaviors associated with infants' weight status. METHODS Six mo...
یکی از مهمترین پدیده های دینامیکی سیستم قدرت که در محدوده زمانی یک تا چند ثانیه اتفاق می افتد و عموما" منجر به عملکرد اشتباه رله های حفاظتی می شود، نوسان توان است . این پدیده با وقوع خطایی در سیستم قدرت و نوسانی شدن متغیرهای ولتاژ و جریان اتفاق می افتد. در این حالت امپدانس دیده شده توسط رله های دیستاس موجود در شبکه (z v/i) نوسانی شده و ممکن است وارد یکی از نواحی عملکرد حفاظتی رله ها شود و در نه...
OBJECTIVE To determine whether previously identified adult obesity susceptibility loci were associated uniformly with childhood BMI across the BMI distribution. DESIGN AND METHODS Children were recruited through the Children's Hospital of Philadelphia (n = 7,225). Associations between the following loci and BMI were assessed using quantile regression: FTO (rs3751812), MC4R (rs12970134), TMEM1...
let x ,..., xn 1 be a random sample from a distribution with sample mean x and samplevariance s 2. in this paper we consider certain very general properties of the so-called “z-scores”x x s i n i ( − )/ : = 1,...., . a representation theorem is then given for z-scores obtained from an underlyingnormal population, together with a theorem for their limiting distribution as the sample size tends t...
in this paper we consider the group algebra $r(c_2times d_infty)$. it is shown that $r(c_2times d_infty)$ can be represented by a $4times 4$ block circulant matrix. it is also shown that $mathcal{u}(mathbb{z}_2(c_2times d_infty))$ is infinitely generated.
