In this paper, we study the challenge of feature selection based on a relatively small collection of sample pairs {(xi , yi)}1≤i≤m. The observations yi ∈ R are thereby supposed to follow a noisy single-index model, depending on a certain set of signal variables. A major difficulty is that these variables usually cannot be observed directly, but rather arise as hidden factors in the actual data ...

Maternal yolk androgens in avian eggs have been shown to affect numerous offspring traits. These changes in offspring phenotype represent examples of maternal effects and are thought to adjust offspring development to the posthatching environment. When studying the functional consequences of yolk hormones it is, therefore, crucial to manipulate the yolk androgen concentrations as well as the en...

The objective of this study was to evaluate the internal quality and lipid oxidation eggs coated with a carnauba wax-based product at different concentrations stored for up 28 days under two temperatures. For analysis quality, were assigned completely randomized 3 x 4 factorial design (uncoated (control); wax 12% concentration (Aruá®); 15% four storage periods - 7, 14, 21, days). Fifteen from e...

of yours truly; but now the CV of a successful applicant looks like that of a newly minted full Professor from olden times. Notwithstanding these demands, and the associated high quality of a fledgling facultylevel type, the job starts with some ‘setup’ money for equipping the lab; but next to no means are provided to initiate that ‘research program’ and to sustain it during the years to come. ...

The purpose of the study was to examine impact adding Fennel seeds (Foeniculum vulgare L.) into diets laying hens on egg quality. This conducted in poultry fields belonging Department Animal Production, College Agriculture, and University Anbar for 12 weeks. A total 72 (Lohman Brown) were used this experiment, at age 43 Hens randomly distributed six treatments groups with four replicates per tr...

in this study, the effects of coating with whey protein concentrate (7.5% w/v) alone and/or in combination with rice bran oil (0.2, 0.4, 0.6 g in 100 ml coating solution) and zataria multiflora extract (1 and 2 μl in 100 ml coating solution) on the quality attributes and egg shelf life were carefully observed and analyzed. weight loss, haugh index, yolk index, ph, air cell depth, shell strength...

The size |Y | of the output space Y is exponential and optimization over the entire space Y is computationally expensive. Hence in the sequential dual optimization method, the optimization of (A.6) is restricted to the set Yi = {y : αiy > 0} maintained for each example. For clarity, we present the sequential dual optimization method to solve (A.2) in Algorithm 3. The algorithm starts with Yi = ...

This reseacrh aims to find out the effect of probiotic administration Bacillus subtilis BN Strain on shell thickness, white index and chicken yolk index. research used 38-week-old layer laying hens as many 24 heads, randomized into four treatments with eight replays. Treatment consists P0 without addition probiotics, P1 0.005 grams / kg feed, P2 0.01 feed P3 0.02 feed. Based analysis statistica...

Background and Objectives: Increased environmental concerns about synthetic packaging have promoted developments of novel, environmentally-friendly edible films. In the present study, the quality parameters of chicken egg coated with pectin or pectin incorporated cinnamon hydrosol was assessed. Materials and Methods: Egg chicken were coated with pectin and pectin prepared with cinnamon hydroso...
