Abstract Study question Does genomic instability contribute to common mechanisms underlying variable defects of gonadal differentiation and susceptibility germ cells cancer? Summary answer Genomic DNA damage associated phenotypes in leukocytes tissue indicate systemic dependence on repair mechanisms, connected cell tumorigenesis when defective. What is known already Variabilities related dysfun...
In many machine learning task, we have data Z from some distribution p and the task is to minimize the risk: R(f) = EZ∼p[`(f(Z), Z)] (11.1) where ` is a loss function of interest, e.g. in classification Z = (X,Y ) and we use 0/1 loss `(f(Z), Z) = 1f(X)6=Y , in regression Z = (X,Y ) and we use squared error `(f(Z), Z) = (f(X) − Y ) and in density estimation Z = X and we use negative log likeliho...
We describe a method for simultaneously determining albumin, by using bromcresol purple, and calcium, by using Arsenazo III, in the same analytical cuvette on the Hitachi 704. Both assays agree well with accepted procedures. The standard curves for the albumin and calcium assays are linear from 0 to 60 g/L and 0 to 5.0 mmol/L, respectively. Calibration is stable for 7 days with use of open reag...
The selective multitest Boehringer Mannheim/Hitachi 704 analysis system was examined according to the ECCLS guidelines in a multicentre evaluation involving four laboratories. Ten routine parameters, covering most of the application settings of the instrument, were measured in the respective laboratory at temperatures 25, 30 or 37 degrees C. The trial lasted four months and gave more than 40,00...
1. Integral Estimate: Ĥ(x) = − ∫ p̂(x) log p̂(x)dx 2. Re-substitution Estimate: Ĥ(x) = − 1 n ∑n i=1 log p̂(Xi) where p̂ is obtained using the samples {X1, ..., Xn}. 3. Splitting Data Estimate: Ĥ(x) = − 1 m ∑m i=1 log p̂(Xi) where p̂ is obtained using the samples {Xm+1, ..., Xn}. A cross-validation estimate can be defined similarly, e.g. the leave-one-out estimate is given as Ĥ(x) = − 1 n ∑n i=1 log p̂...
An experiment was conducted to study the effects of plant density and cultivars on seed yield and yield components of corn (Zea mays L.) under the climatic conditions of Khorramabad at the Agriculture Research Station of Sarab Changaei. This experiment was a factorial on the basis of a randomized complete block design (RCBD) with four plant densities (6.5, 7.5, 8.5 and 9.5 plant/m2), three cor...
