We show that for lazy simple random walks on finite spherically symmetric trees, the ratio of mixing time and relaxation is bounded by a universal constant. Consequently, any sequence trees do not exhibit pre-cutoff; this conclusion also holds continuous-time walks. This answers question recently proposed Gantert, Nestoridi, Schmid. hitting times vertices are (uniformly) non concentrated. Final...

Recently a conformally invariant action describing the Wilson-Fisher fixed point in D=4−ϵ dimensions presence of finite UV cutoff was constructed [44]. In present paper we construct two composite operator perturbations this with definite scaling dimension also cutoff. Thus (as well as action) is defined at all momenta 0≤p≤∞ and low energies they reduce to ∫xϕ2 ∫xϕ4 respectively. The constructio...

the effects of aflatoxin (af) (0.0 and 0.5m g kg-1) and high grade sodium bentonite (hgsb) (5, 7.5 and 10 g kg-1) were tested in an in vivo study including 8 dietary treatments with three replicates of 14 birds per diet per replicate, using a total of 336 broiler chicks up to five weeks. results showed that chicks receiving af contaminated feed had significantly (p≤ 0.05) suppressed body weight...

background & aim: the most common primary brain tumors of the central nervous system are gliomas. among a number of different biomolecular events, a strong relation between oxidative stress pathways and the development of this cancer has been proved. oxidative stress (os) is the consequence of an imbalance between pro-oxidants and antioxidants towards pro-oxidants. the pro-oxidants cause lipid ...

The independent influences of aging and schooling on the development of phonological awareness were assessed using a between-grades quasie.xperimental design. Both schooling (first grade) and aging (5-7 years] significantly improved children's performance on tests of phonemic segmentation, hut the schooling effect was four times larger than the aging effect. The schooling ^.ff^ct »'«-y attribut...

The East process is a 1D kinetically constrained interacting particle system, introduced in the physics literature in the early 90’s to model liquid-glass transitions. Spectral gap estimates of Aldous and Diaconis in 2002 imply that its mixing time on L sites has order L. We complement that result and show cutoff with an O( √ L)-window. The main ingredient is an analysis of the front of the pro...

decreased immune response and dysregulated coordination between inflammatory and inflammation-neutralizing processes. The decline in immune competence is invariably seen with aging. As a consequence, viral or bacterial infections, chronic inflammatory disorders, autoimmune diseases, and cancers are more prevalent in elderly. In addition to genomic and epigenomic instability with age, decreased ...

OBJECTIVE The clinical behavior of meningiomas is not entirely captured by its designated WHO grade, therefore other factors must be elucidated that portend increased tumor aggressiveness and associated risk recurrence. In this study, the authors identify multiparametric MRI radiomic signatures using Ki-67 as a prognostic marker outcomes independent grade. METHODS A retrospective analysis was c...
