Two experiments were conducted to determine effects of feeding corncobs of various mean particle size (MPS) on ruminal, digestive and metabolic characteristics of early-weaned lambs fed pelleted 74.9% concentrate:25.1% corncob diets. The MPS of corncobs in diets was 6.5, 5.4, 1.4 and .8 mm, respectively. As particle size decreased, percentage starch decreased and percentage neutral detergent fi...

Huxley equation is a core mathematical framework for modern biophysically based neural modeling. It is often useful to obtain a generalized solitary solution for fully understanding its physical meanings. There are many methods to solve the equation, but each method can only lead to a special solution. This paper suggests a relatively new method called the Exp-function method for this purpose. ...

Abstract. This paper discusses a method based on Laguerre polynomials combined with a Filtered Conjugate Residual (FCR) framework to compute the product of the exponential of a matrix by a vector. The method implicitly uses an expansion of the exponential function in a series of orthogonal Laguerre polynomials, much like existing methods based on Chebyshev polynomials do. Owing to the fact that...

Two commercial feedlot experiments were conducted to determine the effects of feeding melengestrol acetate (MGA) or MGA plus ractopamine (MGA+OPT) on the performance and carcass characteristics of finishing heifers. In Nebraska (Exp. 1), 1,807 heifers (337.3 ± 20.0 kg) and in Texas (Exp. 2), 1,964 heifers (331.5 ± 6.1 kg) were fed 0.4 mg of MGA daily. For heifers fed MGA+OPT, 200 mg of ractopam...

The purpose of this paper is to explore the relationship between I∆0+exp and its weaker subtheories. We give a method of translating certain classes of I∆0+exp proofs into weaker systems of arithmetic such as Buss’ systems S2. We show if IEi(exp) ` A with a proof P of expindrank(P ) ≤ n + 1 where all (∀ ≤: right) or (∃ ≤: left) have bounding terms not containing function symbols then Si 2 ⊇ IEi...

When feedlot pens are scraped in the spring and summer, manure is often stored before land application can occur in the fall. Manure stockpiled or composted was evaluated for nutrient losses in 2 experiments for 104 (Exp. 1) and 111 d (Exp. 2). Stockpiles (n = 2 in Exp. 1 and n = 3 in Exp. 2) and compost windrows (n = 6 in Exp. 1 and n = 4 in Exp. 2) were constructed with feedlot manure scraped...

Background: Aflatoxins are fungal secondary metabolites negatively affecting ruminant performance; however, little information is available on their impact on rumen fermentation. Aims: This study aimed at determining the effects of different concentrations of aflatoxin B1 (AFB1) from Aspergillus flavus on in vitro gas production and ruminal fe...

The Gaussian kernel encourages similarity between inputs based on their Euclidean distance. Because we’re not dealing with probabilities which must sum to 1, we can omit the normalization constant found in the Gaussian distribution. But the shape is the same: we strongly encourage similarity among nearby inputs, while as inputs get further away, we encourage similarity by an amount that decreas...

(L1) ∣∣∣∣ ẏ = by, y(0) = x0, ẋ = ax, x(0) = y(t), (L2) ∣∣∣∣ ẏ = ay, y(0) = x0, ẋ = bx, x(0) = y(t). Pour le système (L1), on a clairement x(t) = exp(at)x(0) = exp(at)y(t) = exp(at) exp(bt)y(0) = exp(at) exp(bt)x. Le calcul pour (L2) se fait de la même manière et donne le même résultat. On appelle splitting de Lie les deux méthodes (L1) et (L2). Pour une équation scalaire, ces deux méthodes sont...
