Global solvability and boundedness to a attraction–repulsion model with logistic source

Boundary Value Problems
In this paper, we deal with an attraction–repulsion model with a logistic source as follows: { u t = Δ u − χ ∇ ⋅ ( u ∇ v ) + ξ ∇ ⋅ ( u ∇ w ) + μ u q ( 1 − u ) in  Q , v t = Δ v − α 1 v + β 1 u in  Q , w t = Δ w − α 2 w + β 2 u in  Q , $$\begin{aligned ...

Virtual reality vitrectomy simulator [PDF]

, 1998
With the advent of Virtual Reality, surgical simulators have been proposed as a supplement to the education and training of medical residents and post doctoral fellows. A virtual reality simulator can convey the three dimensional anatomical space, provide a means to fine tune surgical skills, and present a variety of pathologies ranging from rare to ...

Recent Progress in the Phase‐Controlled Synthesis of Ruthenium Nanocrystals for Catalytic Applications

Advanced Materials, EarlyView.
Template effect and kinetic control enable crystal‐phase engineering of Ru nanocrystals, granting access to either metastable fcc‐Ru or stable hcp‐Ru with distinct surface structures, thermal stabilities, and catalytic behaviors. Moreover, the hcp‐Ru can further serve as an epitaxial template to direct Pd and Rh nanocrystals into the metastable hcp ...
