PURPOSE Apoptosis is the final common pathway for photoreceptors in several forms of retinitis pigmentosa. Recent study has shown that continuous light exposure upregulates low-affinity neurotrophin receptor p75 (p75NTR), which is involved in light-induced photoreceptor apoptosis in rat retina. However, the function of p75NTR in inherited forms of photoreceptor degeneration has not yet been exa...

Voronoi and related diagrams have technological applications, for example, in motion planning and surface reconstruction, and also find significant use in materials science, molecular biology, and crystallography. Apollonius diagrams arguably provide the most natural division of space for many materials and technology problems, but compared to Voronoi and power diagrams, their use has been limi...

Rate-Delay (RD) Network Services constitute a promising differentiated-services architecture for multi-provider networks, by offering users a choice between high throughput or low queuing delay at bottleneck links. An RD router provides service differentiation via transmission scheduling and by managing two FIFO queues. To ensure strict delay bounds, an RD router tracks arrival times of packets...

This work is concerned with the existence and uniqueness of generalized (mild or distributional) solutions to (possibly degenerate) Fokker–Planck equations ρt−Δβ(ρ)+div(Db(ρ)ρ)=0 in (0,∞)×Rd, ρ(0,x)≡ρ0(x). Under suitable assumptions on β:R→R,b:R→R D:Rd→Rd, d≥1, this equation generates a unique flow ρ(t)=S(t)ρ0:[0,∞)→L1(Rd) as mild solution sense nonlinear semigroup theory. also class L∞((0,T)×R...
