A mathematical definit on of an information network is constructed with the purpose of developing a theory useful in answering practical questions concerning information transfer. An information network inCludes: (1) use,-s, (2) inf rmation resources, (3) information centers, and (4) the total information transfer structure linking (1), (2), and (3). Emphasis is placed on the message transfer s...

Mitochondrial diseases are severe and largely untreatable. Owing to the many essential processes carried out by mitochondria and the complex cellular systems that support these processes, these diseases are diverse, pleiotropic, and challenging to study. Much of our current understanding of mitochondrial function and dysfunction comes from studies in the baker’s yeast Saccharomyces cerevisiae. ...

Ageing is a complex multifactorial process, reflecting the progression of all degenerative pathways within an organism. Due to the increase of life expectancy, in recent years, there is a pressing need to identify early-life events and risk factors that determine health outcomes in later life. So far, genetic variation only explains ∼20–25% of the variability of human survival to age 80+. This ...

Social isolation can exacerbate the negative consequences of stress and increase the risk of developing psychopathology. However, the influence of living alone on experiences generally considered to be beneficial to the brain, such as physical exercise, remains unknown. We report here that individual housing precludes the positive influence of short-term running on adult neurogenesis in the hip...
متن کاملMath 526: Brownian Motion Notes
Theorem 1. If (Xt) is a Brownian motion, then there exist constants μ, σ 2 such that Xt − Xs ∼ N ((t− s)/μ, (t− s)σ). Proof. Without loss of generality take s = 0 and pick some n ∈ Z and write Xt −X0 = (Xt/n −X0) + (X2t/n −Xt/n) + . . .+ (Xt −X(n−1)t/n). Each term on the right hand side is independent and identically distributed. Letting n→∞, by the central limit theorem, the right hand side mu...
