Previous study and our laboratory have reported that short-wavelength (blue and green) light and combination stimulate broiler growth. However, short-wavelength stimuli could have negative effects on poultry husbandry workers. The present study was conducted to evaluate the effects of human-friendly yellow LED light, which is acceptable to humans and close to green light, on broiler growth. We ...

known in traditional Chinese herbal medicine. They have been widely used in many recipes. Modern pharmacological study has showed that they possess diversified effects, such as inhibition of NO and PGE2 synthesis, immuno-modulation, hepatoprotective, anti-hepatitis, and anti-HSV-II. It had been reported that the alcohol extract of the root of Inula racemosa lowered blood glucose and enhanced li...

Brain-derived neurotrophic factor (BDNF) plays a key role in learning and memory, but its effects on the fiber architecture of the living brain are unknown. We genotyped 455 healthy adult twins and their non-twin siblings (188 males/267 females; age: 23.7±2.1 years, mean±SD) and scanned them with high angular resolution diffusion tensor imaging (DTI), to assess how the BDNF Val66Met polymorphis...

(a) Write down the probability distribution of x. Solution: p(x = 0|μ) = 1− μ, so p(x|μ) = μx(1− μ)1−x, this is known as the Bernoulli distribution. (b) Show that this is a proper probability distribution, i.e. the probability sum up to 1. What is the expectation and variance of this distribution? Solution: ∑ x∈{0,1} p(x|μ) = p(x = 0|μ) + p(x = 1|μ) = 1− μ+ μ = 1 E(x) = ∑ x∈{0,1} xp(x|μ) = 0× p...

We observe coherent, cw, 455 nm blue-beam production via frequency upconversion in cesium vapor. Two IR lasers induce strong double excitation in a heated cesium vapor cell, allowing the atoms to undergo a double cascade and produce a coherent, collimated, blue beam copropagating with the two IR pump lasers.
